Abstract: اجريت الدراسة الحالية على نوعين من المياه العادمة الصناعية المطروحة من مصنع نسيج الديوانية والمياه العادمة البلدية من محطة معالجة الديوانية، وللمدة من ربيع 2011 الى ربيع 2012 وهدفت الى اجراء مراقبة فصلية لنوعية المياه الداخلة لمحطتي المعالجة والخارجة منها | The current study has been conducted on two types of waste water, industrial wastewater from Al - Dewaniyah textile factory station1, station 2 and municipal wastewater from Al - Dewaniyah wastewater treatment plant station 3, station 4 in the City of Al - Dewaniyah - Iraq., for the period from Spring2011 to Spring 2012 and targeted monitoring quarterly the quality of water entering and leaving the stations.The study also includes the evaluation of the efficiency of some algae and aquatic plants to improve water quality via bioremediation of some pollutants in the water. The evaluation of water quality includes18 parameters as confirmed on spatial and temporal changes of these parameters, as well as the algal contents of these four stations(S1, S2, S3and S4). The results of physical and chemical analysis show the following ranges of : temperature (12.5 - 41.5°C), total dissolved solids TDS(692 - 1384.6 mg/l), total suspended solids TSS(58 - 277.4 mg/l), electrical conductivity EC(1225 - 2045µS/cm2), pH(7.0 - 7.8), dissolved oxygen DO(0.7 - 8.51mg/l), biological oxygen demand BOD(48.82 - 205 mg/l), total alkalinity (170.7 - 428 mg/l), total hardness TH (412 - 1623.3 mg/l), calcium (89.7 - 204.14 mg/l), magnesium (37.7 - 332.5 mg/l), nitrite (0.43 - 12.25 mg/l), nitrate(6.18 - 63.75 mg/l), phosphate (0.813 - 20.24 mg/l), lead (0.0983 - 1.076 mg/l), chromium (0.007 - 0.045mg/l), cadmium (0.0374 - 0.326 mg/l) and the total algal number(17.00 - 14202 individual/l).The spatial and temporal variations show significant differences at(P?0.05) among studied factors in the different stations.The qualitative study of algae reports that the dominance is to the blue green algae(Cyanophyta)by 46%, then is followed by diatoms(Bacillariophyta) by 26% down with Dinophyta3%, according to Shannon - Wiener index of diversity (H), the fall and winter classified as severely polluted all around the stations 0.377 and 0.669, respectively, while summer and spring are moderate pollution of a category (II) and the values of (H) is1.374 and 1.395 respectively, in situ has been observed that the stations are classified as highly polluted and have been ranked within the category(I) and the stations arranged according to the pollution as S3 <S4< S2< S1.According to Species richness index the first station S1 is the best, follows by S4, S3 while S2 comes the last in order, but in the terms of total abundance has topped the third station S3 among the others, then followed by S4, S2 and finally S1. on the other hand the current study includs laboratory investigation to demonstrate the efficiency of algae and aquatic plants to improve water quality as it has been experimenting with immobilization of algae technique, a new method has been used for the first time at the local level in the current study. The results show that the immobilized algae Stigonema sp.and Cladophora glomerata have lowered the pH of the treated wastewater which began relatively high, as well as increasing dissolved oxygen concentrations at the end of the experiment all transactions free and immobilized treatments , on the other side TSS has been reduced about 61.8% when treated with immobilized algae C.glomerata, nitrite has also been reduced at about 96.7% and 85.5% by Stigonema sp.and C.glomerata respectively, nitrate also has been reduced by 99.9% and 95.2% when treated with Scendesmus dimorphus and C.glomerata respectively, while the removal of phosphate reaches its peak when it has been treated with free Stigonema sp. and immobilized S.dimorphus by 99.92% and 98.35% respectively.The tested algae shows a great ability to reduce heavy metals, when immobilized alga Oscillatoria sp. removes about 94.27% of Lead, while free Stigonema sp. and C.glomerata are the best in Chromium removal about 92.42% and 92.35% respectively, and the C.glomerata is the best in Cadmium processing, a reduced rate of 99.21% followed by immobilized S.dimorphus of 97.13%. The current study also involves a laboratory experiment to evaluate the potential of two aquatic plants duckweed (Lemna minor L.)and water hyacinth Eichhornia crassipes Mart.(Solms.) in improving the quality of wastewater the tested plants have been worked at increasing the aeration of treated water by raising dissolved oxygen concentration about 85.26% and 84.4% for duckweed and water hyacinth, on the other hand the relative efficiency to reduce the pollutants by aquatic plants as follows : EC, NO2, NO3(31.66% and 28.45%, 55.7% and 50.01%, 55.7% and 13.3%)for duckweed and water hyacinth respectively, from another side water hyacinth is the most efficient in phosphate reducing at rate of 90.5% comparing with duckweed 49.78%.On the of heavy metals treatment the tested plants show a remarkable removal of lead 88.23% and 80.4% , chromium 97.84% and 95.18% for duckweed and water hyacinth respectively, with respect to cadmium, water hyacinth shows high efficiency in the removal of this metal by 98.14%, while duckweed is the least in the treatment of Cd by 81.8%. From the above results, the current study demonstrates that there are a spatial and temporal variations regarding the factors examined in the stations of wastewater treatment units and confirms that the efficiency of studied wastewater treatment stations is below the required level, which contributes in increasing the pollution of Al - Dewaniyah River, which is the unique source to supply the city with freshwater for all purposes, that receives large loads of pollutants.The study also confirms that the evaluation of the presence of algae in the studied stations.Thus the knowledge of algal composition could give an early warning and accurate assessment about the quality of sewage before dumping into river. In addition to the forgoing, it is concluded that the biological treatment (bioremediation) of wastewater using free and immobilized algae and aquatic plants have improved dramatically and tangibly the benefits of the quality of that water being a promising approach of the wastewater treatment as well as being low cost economically.

Abstract: جمعت (500) عينة من المرضى المصابين بالحروق من ثلاث مستشفيات في مدينة بغداد للمدة من 1/6/2007 ولغاية 1/11/2007. زرعت هذه المسحات على الاوساط الزرعية للعزل الاولى وتم تشخيصها بالفحوصات المظهرية والبايوكيميائية. اظهرت (489) عينة ملوثة بالبكتريا وبنسبة | • Five hundreds swabs were collected from patients suffered from burns in three hospitals of Baghdad city, for the period from 1st June 2006 to 1st November 2007. The swabs were implanted in order to be isolated and diagnosed by morphological and biochemical tests. • The results showed that 489 swabs were contaminated with bacteria (97.8%), while 11 swabs were not (2.2%). The identification and prevalence of the bacteria was as follow Pseudomonas aeruginosa was found in 148 swabs (30.27%), Klebsiella pneumoniae in 102 (20.26%), Staphylococcus aureus in 79 (16.16%), Escherichia coli in 70 (14.31%), Proteus mirabilis in 52 (10.63%) and Enterobacter cloacae in 38 (7.77%). • Information card for each patient was assigned included age, sex, time of suffering from burns, social status and address.• The degrees of suffering were as follow : - First degree of burns, 201 cases (40.2%). - Second degree, 187 cases (37.4%). - Third degree, 112 cases (22.4). Sensivity test to antibiotic and was done for all the isolated bacteria, and it was found, that, they were sensitive to Vancomycin, Ciprofloxacin, Amikacin, Tetracyclin and Fusidic acid within the percentage ratio of 0.0, 59.1, 3.7, 58.5 and 11.6%, respectively. Also it was found that the investigated bacteria showed high Vesistance to Penicillin G (87.9%), Erythromycin (93.9%), Trimethoprim (100%), Carbencillin (83.9), Cefotaxime (63.4%), Ampicillin (75.9%), Gentamycin (67.9%), Streptomycin (83.6%), Nalidix acid (89.4%) and Linomycin (83.2%). o Searching for the active compounds in the extracts of investigated plants (Linum usitatissimum, Nigella sativa and Eruca sativa) was conducted. It was found, that, the seeds of the three plants contained Glycosides, Alkalis, Flavonoids, Soapiness and Resins, which are not water soluble, but could be detected by the alcoholic extraction. Cumarin was noticed in the seeds of N. sativa and E. sativa only. o Different concentrations of water and alcohol extracts were prepared in addition to the isolation of oils, soapiness and Flavonids. The effectiveness of the extracts was tested at the concentration of 16, 32, 64, 128, 256 mg/ml for all the plants, against the bacteria.o The Phenol, water and alcohol extracts of L. usitatissimum and E. sativa showed high effect against the bacterial species, while that of N. sativa was less affective.o The Minimum inhibition concentration (MIC), was found to be different according to the type of extract and the species of bacteria.o The effects of the organic acids (Acetic, Citric, and Lactic) were tested at concentrations of 0.5, 1, 1.5, 2, 3 and 4% of each acid. An increase in the diameter of inhibition area, related with the increase in the acid concentrations, was detected. It was found that the acetic acid was more affective against the microorganisms, followed by the Citric acid and then the Lactic acid.o on the base of ratios of inhibition area diameters (in vitro), the results illustrated that E. coli was more affected by Acetic acid when the diameters reached 18.75, 21.75, 30.75, 38.25, 40.00 and 44.75 mm, respectively. The concentration of 1.5% was the effective enough against E. coli as diameters rates for P. mirabilis were 19.25, 18.25, 18.0, 22.56, 27.75 and 31.0 mm, respectively, followed by Ps. aeruginosa, S. aurues and En. cloacae when exposed to the optimum concentrations of Acetic, Citric, Lactic acids. The diameters at concentration of 4% were 23.50 and 23.66 mm. o The water extracts from all the involved plants, in addition to the organic acids showed good levels of effectiveness against the different studied bacterial species, when suffered by burns rats were exposed to them. A clear decrease in bacteria numbers in these rats in comparison with non - treated animals, in the swabs removed from the treated and non - treated rats, in addition to the absence of any histophathalogical changes in livers and skins of the treated animals. o Biochemical tests of serums from animals treated with the water extracts and organic acids at concentration of 16 mg/Kg and 18 mg/Kg for seven days and the microscope investigation, proved that these compounds were not toxic.o The effects of the water extracts and the organic acids were studied too from the point of the immunity point of view. An increase in the Levels of IgG and IgA of the supplementary systems C3 and C4 was noticed in the suffered from burns in general. The levels of IgG and IgA tended to be normal after the treatments with the water extract from the studied plants and with the organic acids.o The L D50 of N. sativa and E. sativa was 18 mg/kg while it was 16 mg/Kg of L. usitatissimum.

Abstract: اجريت هذه الدراسة في حقل خاص لمنطقة البركة (30) كم شمال شرق مدينة كربلاء اثناء موسم النمو 2012للعروتين الربيعية والخريفية باستعمال الاصص البلاستيكية. هدفت الدراسة معرفة تاثير الاجهاد المائي والرش بحامض البرولين وتداخلاتها في المؤشرات المظهرية والفسلجية و| This study was conducted in a private field at Albargah district (30Kms) northern east of Karbala city during spring and fall of 2012 growing season using plastic pots. The goal was assess the effect of water stress, foliar application of proline and their interactions on characteristics morphological, physiological and nutritional status of three genotypes of maize namely : Serour, 5018, and Baghdad - 3.The characteristics included root's volume, root's length, root's diameter, root's dry weight, plant height, leaves number, leaf area, shoot dry weight, root/shoot ratio, absolute and relative growth rates and content of chlorophyll and proline in the leaves. The nutritional status included, the concentration, the contents and the rates of absorption and transport of N, P, K, Ca and Mg.In addition to the molecular study which included the technique of Random Amplified Polymorphic DNA (RAPD) DNA. A Factional experiment within Completely Randomized Design (C.R.D.) was adopted i.e. three genotypes of maize namely : Serour, 5018, and Baghdad - 3, proline (0, 50, 100 and 150) mg. L - 1 and two levels of field capacity (50 and 100) % with three replicates in a total of 72 experimental units.Means were compared using the least significant difference (LSD) at 0.05 probability level. Results could be summarized as follow : 1 - Genotypes significantly differed in the studied traits.The cultivar 5018 gave the highest values of root's volume, root's length, root's diameter, root's dry weight, plant height, and root/shoot ratio for spring and fall cultivations.The same cultivar gave higher values of P%, Ca%, Mg% in roots and the content of N, P, K, Ca and Mg in roots, rates of absorption and transport of N, P and Ca in spring and fall cultivations.Leaves P%, Ca% and Mg %, leaves Mg content and absorption and transport of Mg in fall cultivation. on the other hand, Serour cultivar give higher values of leaves number, leaf area, shoot dry weight, absolute and relative growth rates, content of chlorophyll and N% in root in spring and fall cultivation. P% in leaves in fall cultivation, leaves K% in both cultivation, content of N, P, K and Ca of shoot in both cultivations, shoot's Mg content of shoot in fall cultivation, content of N, P, K and Ca of shoot in both cultivation and Mg content of shoot in fall cultivations. Baghdad - 3 cultivar give higher values of proline content, Mg% in roots in both cultivations, shoot Mg% in fall cultivations, absorption and transport rates of K in fall cultivation, transport rate of Ca in spring and fall cultivations and absorption and transport rates of Mg in fall cultivation. 2 - Apart from Ca% of root in spring and fall cultivation, the proline markedly influenced all the rest traits where 100 mg. L - 1 proline gave the highest values compared to control treatment (i.e. 0 proline) that gave the lowest values. The proline at 50 and 150 mg. L - 1 gave intermediate values for all studied traits. 3 - Apart from some cases, 100% field capacity treatment gave higher values of most studied parameters. The field capacity of 50% gave higher values of N% and K% in roots and leaves, the content of N and K of roots and shoots and rates of absorption and transport rates of K in spring and fall cultivations. on the other hand, there was no effect of field capacity on Ca% of roots and shoots in spring and fall cultivation and Mg% of roots in spring cultivations. 4 - Bi and Tri interactions effect was profound on most studied characteristics. 5 - Through molecular study that including isolation of DNA in leaves of maize , a quantity of DNA ranging between 150 - 290 nano - gram / ?l with 1.8 - 1.9 purity was obtained. The differentiation of (RAPD) DNA was analyzed in order to prepare the finger print of maize genotypes. Six primers were tested (OPA - 09, OPA - 11, OPA - 13, OPC - 12, OPD - 20 and OPN - 16). The primers revealed different multiplication products between genotypes.The least value of genetic distance was 0.4103 between 5018 and Baghdad - 3genotypes, while the highest value of genetic distance was 0.7932 between Serour and 5018 genotypes.Data analysis revealed that these genotypes are divided into two main groups namely : group included 5018 and Baghdad - 3 genotypes, and group included Serour genotype only.

Abstract: Two hundred and thirty clinical specimens were collected from two different hospitals in Baghdad during the period (December 2012 to April 2013). These specimens were collected from visitors, hospitalized patients and the health care workers in these hospitals. The specimens included nasal swab, wound swab, burn swab, abscess and pus, sputum, ear swab, urine and blood culture diagnostic results show that 150 out of the (230) specimens gave positive bacterial cultures and (100) isolates are characterized as Staphylococcus aureus depending on the cultural and biochemical examinations.the coagulase test was performed and the results showed that from total 150 isolates of Staphylococci, 100 isolates (61%) were coagulase - positive (COPS), while only 50 isolates (39%) were coagulase negative (CONS). In addition, the distribution of methicillin resistance among Staphylococcus spp. was investigated.The use of the antibiotic susceptibility profile for these isolates was examined against methicillin resistance. Using disk diffusion method revealed that (13) isolates were proved to be methicillin resistant Staphylococcus aureus (MRSA), While (87) isolates of S. aureus showed sensitivity to methicillin (MSSA) and there was no intermediate resistance among these isolates.The ability of MRSA isolates to produce some virulence factors were investigated and the results showed that MRSA isolates produce many enzymes and toxins that contributed in their virulence such as protease, urease, dnase and gelatinase, and also produce a beta types of haemolysins.The ability to produce slime layer by MRSA isolates was also investigated and the results showed that all isolates of MRSA were produced slime layer when theytested by Congo red agar method and the results showed that all of MRSA isolates produced strong slime layer.One of the aims of this study was to adopted a accurate diagnostic method to detect S.aureus by its genetic material contents through extracting of DNA and gel electrophoresis of the PCR product for the specific gene.Detection of methicilline - resistance gene represented by A confirmatory test was carried out for the selected isolates using Polymerase chain reaction (PCR) technique for further characterization up to the species level by the amplification of (mecA) gene.This is Staphylococcus aureus specific gene that encodes the extra Penicillin Binding Protein, which is unique to methicillin - resistant staphylococci. All the (13) positive isolates by disk diffusion test are found to be positive for the presence of (mecA) gene as their agarose gel revealed the presence of DNA band of mecA gene with a molecular size about (200 bp.).Results of the detecting (femB) gene showed that it was positive in all of MRSA isolates as they appear to have a band with a molecular size of about (651 bp). The genetic determinants of methicillin resistance mecA and femB genes were amplified using multiplex PCR technique in order to identify methicillin resistant (mecA+) and susceptible (lacking mecA) staphylococci and to differentiate S. aureus (femB+) from coagulase negative staphylococci (lacking femB). All of the S. aureus isolates (100%) were found to harbor femA gene, it is species specific marker for S. aureus.

Abstract: The present study had been carried out to elucidate the toxic effects of sodium fluoride on local rabbit males, this study involved determination of the histological Changes of some organs include (Testes, Liver and Kidney) , moreover study the changes in body weight of the animals and the percentage of organs weight and some blood parameters and biochemistry which include packed cell blood volume (PCV), Hemoglobin (Hb), Total white blood cells, Testosterone hormone, T3, T4 hormones, Glucose concentration, Cholesterol, Urea, Transaminase enzymes and Bilirubin - level in blood. Twenty local adult male rabbits were included this experiment their ages ranged between 10 - 14 months.The animals were treated with oral swallow for 12 weeks. The animals were divided into four groups : control group is treated orally with (0.9%) normal saline; First group was treated orally with 10 mg/kg of body weight sodium fluoride, second group was treated orally with 20 mg/kg of body weight sodium fluoride and third group was treated orally with 30 mg/kg of body weight sodium fluoride. The results of present study showed a significant decreased (P<0.05) in body weight of treated animals with dose of sodium fluoride 20 and 30 mg/kg of body weight, while there is no significant differences in the body weights of treated animals with sodium fluoride dosage of 10 mg/kg of body weight when to compared with control group. The percentage of organ weight to body weight showed a significant decrease in testis weights and liver weight, while there was no significant differences in kidney weight in treated group with sodium fluoride when to compared with control group. Concerning histological changes showed a reduction or freezed stages in spermatogenesis processes which timed with decrease in number of primary spermatocytes and secondary spermatocytes in addition to infiltration of lymphocytes, also found that NaF cause disorganization, denudation, and reduction in germinal epithelial cells of the seminiferous tubules and associated with absence of sperm in the lumina, also showed a decrease in radius of epididymus ducts and decrease in number of sterocilia and decrease number of mature sperms. Histological sections of kidney showed that there was a clear shrinkage of glumeruli.Histological section of kidney of animals that treated with sodium fluoride showed a mild blood vessels congestion, shrinkage in glumeruli, distributed in renal tubules and erode its epithelium with some apoptotic areas. The liver sections appeared appreciable effect with fluoride include dilation in central vein and erode to its epithelium, congestion in hepatic sinusoids with apoptosis and erode to general structure of liver with some of inflammatory cells and death in some cells which lead to erode of typical ray arrangement. Regarding blood parameters the present study showed a significant decrease (P<0.01) in percentage of (PCV) and (Hb) of the animals treated with sodium fluoride, while showed (WBCs) count significant increased compared with control group. Hormonal analysis (Testosterone, T3 and T4) showed a significant decrease, while significant increase of glucose, cholesterol, urea, transaminases enzymes for (AST, ALT) and bilirubin levels. Results obtained from this study and mentioned above may be attributed essentially to that of Naf administration results in sever lesion of male reproductive system wich may be aggravated with increase administration concentration of Naf.

It is followed by AL - Shafiya for 10 cases in 18.18% and the lowerest was AL - Mhannawiya for one case in 1.8%. It has been clear that the number of the multiple epidemics is more than the individual ones in 70.5% while the latter in 29.98% respectively. It was focused on hands and legs in 50.35% and 24.46 %. The tissue test showed thick perspiration in the big infected pharynx and lymphatic cell in addition to the existence of abscess to the smash of the infected cell. Forty nine positive cases were found in 89.09% for the genetic material DNA which is connected with Leishmaniasis by mean of NestedPCR to identify the type results showed 47 samples which is L. major in 95.91% and to get sure by investigating the virulence factor lipophosphoglycan, proteophosphoglycan and cysteine protease it was found that all sample were positive in 100% as Leishmania. major. To know the affect of treatment pentostam on these samples, the standard proportion for the genetic patterns was calculated factor lipophosphoglycan, proteophosphoglycan and cysteine protease during five week. Results showed that there was a big difference for each gene in a solation during the period of treatment in a level of the possibility of (P?0.05) when used test LSD. and by comparing the three genes it was found that there was a meaningful between cysteine protease and the other two factor lipophosphoglycan, proteophosphoglycan and there wasn’t difference between lipophosphoglycan, proteophosphoglycan. Hence, it has been clear that the treatment pentostam has a big affect in parasite by its affect on the virulence factors and this explains that possibility of infection may happen again after having the treatment. The skin disease cutaneous Leishmaniasis is considered as one of the endemic parasitic diseases in Iraq. This study aims at identifying its prevalence and specifying the virulence factors in Cutaneous Leishmaniasis in order to define the type of disease reason and the affect of the treatment of Pentostam on the virulence factors lipophosphoglycan, Cysteine protease, proteophosphoglycans by means Real time - PCR

Abstract: قدر التنوع الوراثي لـ 19 من الانماط الوراثية للطماطة (المحدودة وغير المحدودة النمو) المستزرعة في العراق باستخدام اثنين من واسمات الدنا (DNA Markers) المعتمدة على تفاعلات البلمرة المتسلسلة Polymerase Chain Reaction (PCR) وهما واسمات التفاعل التضاعفي العشوا | Genetic diversity of 19 tomato genotypes (determinate and indeterminate) cultivated in Iraq using two polymerase chain reaction based DNA markers (PCR based DNA markers); Random Amplified Polymorphic DNA (RAPDs) and Simple Sequence Repeats (SSRs).Variation of some growth criteria and morphological traits for each genotype were recorded in the growing season of 2012 - 2013.High variability was observed in plant height, leaf area, number of inflorescence, number of flowers and fruit weight among genotypes To achieve PCR reactions, total genomic DNA was isolated from fresh leaves (2 weeks old). The average yields of DNA were in the range of 100 - 295 ng/?l with a purity ranging between 1.8 - 1.9.RAPDs amplifications were performed for genotypes fingerprinting by testing 27 Operon primers. DNA polymorphisms among genotypes were scored within detectable amplified fragments (their numbers and molecular weight) after agarose gel electrophoresis and staining with ethidium bromide. The 27 primers produced 442 of main bands, out of which 312 were polymorphic bands (70.5%) and 70 were monomorphic (15.8%) across all tested genotypes.Each selected primer produced between 60 bands (OPA - 14) to 290 bands (OPD - 13). DNA amplification products ranged in their size from 250 bp (OPA - 01, OPU - 14, OPX - 15, OPX - 19, OPT - 08 ( to 2755 bp (OPX - 18). The highest number of polymorphic bands (21 bands) was produced by primer OPU - 03, while the lowest number of polymorphic bands (3 band) was produced by both primers OPA - 14 and OPB - 17.The primers varied in their capacity in producing polymorphic amplified profiles among tomato genotypes which individually reflected genotype specific DNA profiles (fingerprints). The most important primers for this purpose were primers that produced more variety specific DNA profiles, such as OPD - 13, OPT - 08, OPW - 04, OPA - 04, OPA - 15, OPB - 18, OPU - 03, OPC - 09.The highest value of discrimination among genotypes in this study was obtained by primer OPU - 03, while the lowest discrimination value was produced by both primers OPA - 14 and OPB - 17. The primer efficiency ranged from 0.13 in (primer OPC - 09) to 0.02 in (primer OPB - 17). The lowest genetic distance was 0.2294 between genotypes Oula and Shady lady, while the highest genetic distance was 0.9459 between genotypes Fotton and Special pack. Cluster analysis (Phylogenetic tree) by un weighted pair - group method of arithmetic means (UPGMA) based dendrogram revealed that they were two main genetic groups (major clusters).The first small major clusters included four (four genotypes) while the second large major cluster included (15 genotypes). A total of 21 alleles were detected among the tested genotypes using five SSRs loci distributed on four chromosomes of tomato. The molecular size of bands obtained from amplification of SSR products ranged from 121 to 247 bp. Alleles ranged from one in (Tom 8 - 9, Tom 41 - 42 and Tom 67 - 68 loci) to twelve in Tom 49 - 50 locus. The values of heterozygosity for each locus ranged between 0.63 for Tom 31 - 32 and 0.89 for Tom 49 - 50 with a mean value of 0.30. The polymorphic information content (PIC) values for the SSR loci ranged from 0.45 in Tom 31 - 32 to 0.58 in Tom 49 - 50 loci with an average of 0.21. Each one of (Tom 8 - 9, Tom 41 - 42 and Tom 67 - 68 loci) produce 0.0 value for both heterozygosity and PIC. The study revealed that, The lowest genetic distance was 0.3244 between varieties Tamara and W arda, while, the highest genetic distance was 0.9177between varieties Helam and Super marimond. The genetic similarity values ranging from 0.0823 to 0.6756 depending upon the genetic distance values that ranging from 0.3244 to 0.9177, indicating the largest diversity with percentage of 32 to 91% among the tested genotypes. The analysis of the results obtained from genetic distances and Neighbor - joining dendrogram (unrooted tree) revealed that, the 19 tested tomato genotypes can be grouped into two major groups : first cluster included nine varieties distributed in two subgroups. The second major cluster included 10 genotypes which in turn divided into two subgroups.The relationship among genotypes was not concern to their morphological characters and geographical origins. The overall analysis of the results show that both SSRs and RAPDs markers are powerful tools in fingerprinting and revealing the genetic relationships among tomato genotypes.

Three taxa of aquatic plants were selected (Phragmites australis Trin ex stand, Ceratophyllum demersum L. and Typha domengensis Pers) in three sites within Al - Auda Marsh; these sites were Al - Adleh, Al - Auda and Um - Almashahef. Also, the study included measuring physical and chemical factors of all the study sites, such as : temperature (air and water), power of hydrogen (pH), total hardness(TH), Calcium (Ca), Magnesium (Mg), turbidity (Tur.), light penetration(LP), depth of water (D), total dissolved suspend material (TDS), total suspended solids (TSS), total alkalinity (TA), dissolved oxygen (DO), total nitrogen (TN) and total phosphorus (TP) and reactive Silicate (SiO3). The mean ranges of the studied factors were recorded : air temperature (10 - 38 C°), water temperature (13 - 34 C°), pH (7.1 - 8.6), TH (672 - 3800mg/l), Ca (97.8 - 264.5 mg/l), Mg (125.1 - 896.13mg/l), Tur.(7.62 - 30.7NTU), LP(46 - 113cm), D (190 - 413cm), TDS (1170 - 3075 mg/l), TSS (0.02 - 0.08 mg/l). while TA (207.5 - 300mg/l), DO (6.4 - 13.5 mg/l), TN (2.41 - 8.58µg/l), TP (0.013 - 0.23 µg/l) and SiO3(101 - 776.77 µg/l).Results of the study indicated presence of 111 taxa of epiphytic diatoms, which belonged to 13 families and 26 genus (one family and two genus of centric diatoms, 12 families and 26 genus of pennate diatoms).The present study recorded 21 species that were found only on one host plant, 20 species that were found on two host plants and 70 species that were found on all host plants, nine of diatoms taxa were present in all host plants among all study seasons which are Achnanthes minutissima, Cocconeis placentula var. euglypta, Cyclotella meneghiniana, Synedra affinis, Syneda ulna , Gomphonem parvulum, Mastogloia smithii var. amphicephala, E. zebra var. porcellus, Rhopalodia gibba.One of the diatoms taxa was recorded in the present study is new to Iraqi flora, the new record of diatom include one taxa of Achnanthidiaceae family (Achnanthes exigua var. constricta). The results of this study included description of the basic characteristics of this taxa with complete photographic documentation.It was evident, from the results, that the morphological form of host plants influenced the number of the attached epiphytic diatoms. C. demersum had attracted 92 diatoms taxa(35%) while the lowest number was 82 taxa (31%) attached by Typha domengensis. The seasonal variation of diatoms growth was evident. Spring 2014 was characterized by the highest number of attached taxa (69 on P. australis - 11%) whereas the lowest number was observed on C. demersum (32 taxa - 5.4%) in autumn 2013.Numbers of epiphytic diatoms fluctuated among study sites, seasons and aquatic plants. The total number of epiphytic diatoms on P. australis ranged between 0.73×104 cell/gm wet weight in summer 2014 at Al - Auda and 406.89104 cell/gm wet weight in spring 2014 at Um - Almashahef. C. demersum recorded highest total number 513.9 ×104 cell/gm wet weight in winter2014 at Al - Adleh, while the lowest total number was 0.1×104 cell/gm of wet weight was recorded in the spring 2014 at Um - Almashahef. While total number of taxa on T. domengensis ranged (0.84 - 427.89) ×104 cell/gm wet weight in summer and winter 2014 at Um - Almashahef.Fluctuations in the total number of main epiphytic diatoms families were observed on all aquatic host plants throughout the study period. The higher total number(92.59×104 cell/gm of wet weight) of diatoms recorded in Achnanthidiaceae family in summer 2014 on P. australis and lower total number (0.28×104 cell/gm of wet weight) on same plant observed in Rhoicospheniaceae family in spring 2014. C. demersum showed highest total number (95.15 ×104 cell/gm of wet weight) in Fragilariaceae family in spring2014, while the lower total number (0.3×104 cell/gm of wet weight) was in family Rhoicospheniaceae in autumn 2013. Individual of Achnanthidiaceae family were recorded as highest total number (168.57×104 cell/gm of wet weight) on T. domengensis in Achnanthidiaceae family in the winter of 2014, but lower total number (0.28×104 cell/gm of wet weight) recorded in Coscinodiscaceae family in the same season. The study showed highest values for richness index (3.77) in the spring of 2014 for epiphytic diatom on C. demersum in Al - Auda site, while lower richness index recorded was (0.6) on T. domengensis in theautumn of 2013 at Um - Almashahef. Shannon - Weaver index ranged (0.24 - 2.45) for epiphytic diatom on P. australis during winter of 2014 at Um - Almashahef and autamn 2013 at Al - Auda, respectively. Highest values for Evenness index were recorded (0.28) for epiphytic diatom on C. demersum in the spring of 2014 at Um - Almashahef site, while for the same site lower values recorded was (0.03) on T. domengensis in winter 2014. Higher percentage for Jaccard similarity index (63.2%) obtained between epiphytic diatoms hosted on T. domengensis and lower percentage of similarity (28.9%) found among the common taxa of epiphytic diatoms on C. demersum, and highest percentage for Jaccard similarity index between host plants was (70%) between P. australis and C. demersum while lower percentage of similarity(67%) was obtained between T. domengensis and C. demersum.

In this study five hundreds thirty four samples of urine and wounds from patients with diabetes and healthy were collected from both sexes and all ages to isolation and identification of pathogenic bacteria by morphological, cultural and biochemical characteristics then determination of virulence factors and genetic variation between dominant type depending on the isolating source and the type of infection in diabetic patients. The counts of urinary tract infections and wound infection in non _diabetic patients were 118 and 52 respectively.The percentage of positive isolation of bacteria for both of them were 44, and 38.4% respectively and from the same patients with urinary tract Infections and wounds and Insulin Depended Diabetes (IDD) patients were 158 and 68 samples respectively and the percentage of bacterial isolation were at 78.5 and 67.6% respectively. The patients with Insulin Non - dependent Diabetes (INDD) were 69 and 42 samples, where positive isolates from bacteria were 75 and 71.4% respectively. The infections females from the Healthy and Diabetes Patients that (IDD) or (INDD) were larger than that of the males patients and with the same state with the wounds infections state for (IDD) patients, whereas the rate was smaller than of males for wounds infections to patients with the other diabetes infections type. The age group between 41 - 60 years was the larger percentage with all infections, except with wounds infections to (INDD) patients, while the age group between 16 - 40 years was the larger, and the infections were the largest means in the Winter and Autumn compare the other seasons.The higher rate of bacteria that isolated from patients with Urinary Tract Infections was Escherichia coli then other types like Citrobacter diversus , Proteus mirabilis, Morganella morganii, and Enterobacter aerogenes. The larger rate of bacteria in patients with diabetes and wounds Infections was Escherichia coli then Citrobacter diversus, Proteus mirabilis, Enterobacter aerogenes, Morganella morganii and Staphylococcus aureus. The rate of diabetes infections with urinary tract infections and wounds increased in winter and autumn seasons more than of summer and spring seasons, Most bacterial isolates where sensitive for chloramphenicol.Other antibiotics were highly variable in their ability to inhibit bacterial isolates.the bacterial isolates were different in their ability to produce virulence factors, the diabetes infections was the reason of increase the variation in their ability to produce that virulence factor and the bacteria that isolated from diabetes patients produced haemolysine factor and capsule.PCR technique was used to show the genetic variations for the more repeats bacterial isolates isolated from all sources infections and used the Specific Primers (KPSMT II) group II capsule, (CNF1) Cytotoxic Necrotizing factor, (CNFs) and (HLY A) haemolysine, the bands appeared after electrophoresis to represent the used Primers, one band was appeared in the sample of diabetes Patients with Urinary Tract Infections(KPSMT II) at molecular weight 270 bp, and one band appeared in the sample of diabetes with urinary tract infections for Primer (HLY A) and it is molecular weight was 177 bp. One band appeared in the sample of diabetes patients for the primer (CNF1)hg with Wound Infections and it is molecular weight 450 bp, and there is not any band in the Primer (CNFs).

Abstract: صممت الدراسة الحالية لغرض التعرف على التاثيرات السمية الوراثية والسمية الخلوية للعقار ميترونيدازول(MTZ) في الفئران البيض Balb/ C والتاثير الوقائي الذي توفره المعاملة المسبقة بالكركم(CUR) في سمية العقار ميترونيدازول. تم استخدام مؤشرات الوراثة الخلوية (النو | The current study was designed to identify the genotoxicity and cytotoxicity of Mitronidazole (MTZ) and protective effect of Curcumin (CUR) against the toxicity of MTZ in whit mice. Cytogenetic endpoints (micronuclei (MN) and mitotic chromosomes), Productive biomarkers (sperms), molecular cytogenetic biomarkers (comet assay), molecular endpoints (genomic and mitochondrial DNA concentration in liver and spleen and testis) and mutation assessment in mitochondrial DNA (mtDNA) of liver and testis by PCR and restriction pattern were used to evaluate genotoxicity, cytotoxicity of MTZ and protective effects of CUR in white Balb/Cmice. The study was conducted in the laboratories of college of education, college of science in Tikrit university and laboratories in the state company for drugs industry - Samarra - Iraq (SDI). Dosages of 30 and 50 mg/kb.b.wt. of MTZ were tested for genotoxic and cytotoxic and mutagenic effects in somatic and sperms of white mice. The dosages 4.5 and 10 mg/kgb.wt. of CUR were used to study the protective effects of CUR in genotoxicity and cytotoxicity and mutagenecity of MTZ. The current study showed that MTZ has genotoxic effect expressed by high frequency of micronuclei in polychromatic erythrocytes (PECs) which reached 15.5 ± 2.88 with the dosage 30 mg/kg.b.wt. and 21.31 ± 4.2 with the dosage 50mg/kg.b.wt. compared with 7.25 ± 1.88 in negative control. In the study of the protective effects of CUR against genotoxic and cytotoxic effects of MTZ, we observed that in mice treated with the dosage 4.5 mg/kg.b.wt of CUR for 9 days before the dosage 50 mg/kg.b.wt. of MTZ, There were significant p<0.05 decrease in MN frequency which reached 13.25 ± 4.19 compared with 21.31 ± 4.2 for mice treated with the dosage 50mg/kg.b.wt. of MTZ withoutCurcumin. The study showed that MTZ has cytotoxicity expressed by significant p<0.05 decrease in mitotic index (MI) which reached 0.010 in bone - marrow of the mice treated with 50 mg/kg.b.wt. compared with 0.023 in negative control. The dosage 4.5 mg/kg.b.wt. of CUR for 9 days before giving the dosage 50 mg/kg.b.wt. of MTZ resulted in returning of MI in bone - marrow 0.021 to its levels in negative control 0.023 compared with its value which reached 0.010 with the dosage 50 mg/kg.b.wt. of MTZ. The two dosages 30 and 50 mg/kg.b.wt. of MTZ caused significant p<0.05 decrease in total number of sperms which reached 2.4±2.4 and 1.5 ± 0.1 milions simultaneously compared with 6.7 ± 0.9 millions in negative control. More over there were significant p<0.05 decrease in motile sperms which reached 25.2 ± 11.0 and 14.6 ± 10.6 compared with 57.6 ± 8.0 of negative control. Significant p<0.01 decrease in the length of mid - piece and total length of sperm tail with the dosage 50 mg/kg.b.wt. of MTZ which reached 19.2 ± 6.0 and 69.0 ± 6.0 simultaneously compared with 31.6 ± 9.0 and 100.3 ± 15.0for negative control. Treating with the dosage 4.5 mg/kg.b.wt. of CUR for 9 day before the dosage 50 mg/kg.b.wt. of MTZ resulted in the return of mid - piece and total length of sperm tail which reached 29.5 ± 3.0 and 95.0 ± 5.0 close to the levels of negative control 31.06 ± 9.0 and 100.3 ± 15.0 simultaneously. Compared to 19.2 ± 6.0 for the length of mid - piece and 69.0 ± 6.0 for total length of sperm tail in mice treated with the dosage 50 mg/kg.b.wt. of MTZ without previous treatment with CUR. The study of damage levels in DNA with comet assay showed that MTZ induced significant p<0.01 levels of damage reached 45.4 ± 2.36 with the dosage 50mg/kg.b.wt. of MTZ in bone - marrow and 36.8 ± 0.58 in liver cells compared with 9.0 ± 2.12 and 5.2 ± 0.58 simultaneously in negative control. There were decrease occurred in the level of damage in DNA of bone - marrow and liver cells. However it did not return to its levels of negative control 9.0 ± 2.12 in bone - marrow and 5.2 ± 0.58 in liver cells. OTM values reached 26.4 ± 1.29 and 24.0 ± 1.14 in mice treated with the dosage 4.5 mg/kg.b.wt. of CUR for 9 days before the dosage 50 mg/kg.b.wt. of MTZ. However The values of OTM lower than its values in bone - marrow 45.4 ± 2.36 and 36.8 ± 1.66 in liver cells of mice treated with the dosage 50 mg/kg.b.wt. without CUR. In the molecular study, The results showed mutagenic effect of the dosage 50 mg/kg.b.wt. of MTZ in mice mtDNA expressed by novel restriction sites for Bam - HI and Hind - III in liver tissue and SauA3 in testis. The treatment of mice with the dosage 4.5mg/kg.b.wt. of CUR for 9 days before the dosage 50mg/kg.b.wt. of MTZ did not resulted in the inhibition of mutagenesis in mtDNA. In conclusion, results of this study showed that MTZ has genotoxic and cytotoxic effects in white mice and mutagenic effect in mice mtDNA. The dosage 4.5 mg/kg.b.wt.of Curcumin has protective effect against genotoxic and cytotoxic effects of MTZ. on the other hand the dosage 4.5 mg/kg.b.wt. of Curcumin has no protective effect against mutagenicity of MTZ in mice mtDNA.

Abstract: اجريت الدراسة الحالية بهدف عزل وتشخيص المكورات المعوية البرازية Enterococcus faecalis من مصادر سريرية مختلفة، وتقييم التغيرات المظهرية والافات المرضية في بعض اعضاء الفئران البيض السويسرية المصابة تجريبيا لذا تضمنت هذه الدراسة محورين رئيسين هما : الجانب ال | The present study was conducted to isolate and diagnose an Enterococcus faecalis which are isolated from different clinical sources, and evaluate the appearance changes and pathological lesions in some Swiss white mice organs which are infected experimentally, so this study deals with two main aspects : The bacteriological type : The results obtained may be summarized as follows : - The total number of (310) clinical samples were collected from Baquba Educational Hospital and Al - Batol Hospital for Maternity and Children in Baquba city from the beginning of March to the end of September (2009) with various ages and from both sexes, including (82) urine samples from patients with urinary tract infections, (46) vaginal swab from infection of female reproduction system, (45) surgical wound swabs, (38) stool sample from patients with abdominal pains and diarrhea, (32) throat swabs from tonsillitis patients, (25) middle ear swabs, (22) burn swabs, and (20) blood sample from patients with bacteremia and prosthetic valvular heart diseases. The isolates diagnose depended on the cultural and microscobial characteristics and biochemical tests, serological diagnosis according to Lancefield method and assertion diagnosis according to (API - 20 Strep) was done to find (32) isolates of Enterococcus : (28) isolates of E. faecalis (87.5%), (3) isolates of E. faecium (9.4%) and one isolate of E.gallinarum (3.1%). - The sensitivity of E. faecalis was tested against (23) different antibiotics. The isolates showed resistance of about (100%) against Aztreonam, Amikacin, Co - Trimoxazole, Cephalexin and Cefotaxime, while the isolates were sensitive about (100%) against Amoxicillin, Nitrofurantoin, Imipenem and Ampicillin, while they showed a various resistance to another antibiotics involved in this study. - The ability of the isolates for producing the Beta - lactamase enzymes was tested by the standard rapid iodometric method. The results showed the disability of these isolates for producing the Beta - lactamase enzymes. - The production ability of E. faecalis for some virulence factors was evaluated. The results showed the ability of these isolates of adherence to the uroepithelial cells of human's urinary system were (93%), and (82.1%) were bacteriocin producer, and (28.6%) were hemolysin producer, and (43%) were gelatinase producer, and (10.7%) were lipase producer, and (35.7%) were capsule producer, and (14.3%) were cytolysin producer, while none of the isolates under the study showed the ability of haemagglutination.Histopathology type : (4.6 x 106) cell / ml concentration of the bacterial suspension of E. faecalis was used orally on mice and histopathological changes were examined after (3, 5, 7, 14) days of infection, which revealed the ability of bacteria for colonization and causing pathological lesions and many histological changes in the liver, kidney, small intestine and hearts of these animals. The damage in the animal tissues of the second group (treated with Streptomycin and EFU10) was more than that in the third group (treated with Streptomycin and EFS14), and fourth group (treated with EFU10 only). Generaly, the most important histopathological changes were the necrosis in some areas, and infiltration of inflammatory cells in infected tissues. These pathological lesions cause damage and decompose of tissues with distortion of their morphologies.

The vaginal examinations were done by gynecologist, two high vaginal swabs were taken from (250) women & a cervical swab from some women with vaginal discharge. General urine examination & blood group with Rh factor were performed for each woman with vaginal discharge. Direct microscopic examination, staining & culture of swabs were performed on different methods for diagnosis of Trichomonas vaginalis, followed to diagnose Candida albicans, Neisseria gonorrhoeae, Chlamydia trachomatis & Treponema pallidum as well as some other bacterial groups. The rate of Trichomonas vaginalis was (2.8%) & Neisseria gonorrhoeae (0.8%), while no Chlamydia trachomatis & Treponema pallidum recorded in this study. The highest rate of Trichomonas vaginalis was among the age group between 15 - 29 years (3.6%), the rate of Trichomonas vaginalis infection was higher among illiterate (5.7%) than educated ones. The highest rate of Trichomonas vaginalis was recorded among those with blood group O & Rh (+ve) (3.8%). The same result was found regarding other microorganisms in both sexes. Statistically the results were not significant.The rate of infections in females was higher than males in all infection except Neisseria gonorrhoeae was recorded highest rate in males(35%). The percentage of mixed infections with Trichomonas vaginalis was Candida albicans (1.6%) & B - hemolytic streptococcus (0.4%). The maximum infections rate in vaginal swabs were Staphylococcus aureus (42.3%) & lowest rate of Neisseria gonorrhoeae (2%). Regarding the distribution of microorganisms isolated from urine samples of females suffering from vaginal discharges, the highest rate of infection was Eschirechia coli (22.2%) & lowest rate of Neisseria gonorrhoeae (2%) respectively. The rate of isolated microorganisms from urethral discharge of males were Neisseria gonorrhoeae (35%) & Escherichia coli (5%). Antibiotics Ciprofloxacin & Amikacin showed good inhibition activity against all pathogenic microorganisms. Regarding the effect of different concentration of metronidazole & medical herbs to the Trichomonas vaginalis invitro, metronidazole showed clear effective inhibition at concentration (1.25%) during 24 hours. The inhibitory effect of Zea mays (both alcoholic & watery extractions) was greater than Apium graveolens & Foeniculum vulgare.

Abstract: اجريت تجارب عدة لغرض دراسة تحمل نبات السيسبان Sesbania rostrata L. للكادميوم والرصاص وكلوريد الصوديوم على مستوى النبات الكامل ومزارعة النسيجية. استحث الكالس واديم على وسط موراشيج وسكوج 1962 والمجهز 0.3 ملغم/لتر من الكاينتين و2 ملغم/لتر من حامض 2, 4 داي مث | Several experiments were carried out to study cadmium, lead and sodium chloride tolerance at the tissue culture or whole plant levels of Sesbania rostrata. Callus was induced and maintained on Murashige and Skooge (1962) medium (MS) supplemented with 0.3 mg/l Kinetin and 2 mg/l 2, 4 - dichlorophenoxy acetic acid (2, 4 - D) using cotyledons as the source for callus induction. Different concentrations of cadmium, lead and sodium chloride directly or gradually were added to the culture medium as contaminants. Selected tolerant cell lines were subjected to regeneration. Callus showed better tolerance to gradual exposure than direct addition. The concentrations of Potassium, lead, Cadmium and Sodium recorded to 17, 24, 27, 35 ppm when 1.0, 2.0 mg/L and 0.4% of cadmium, lead and sodium chloride were added respectively. The study included the effect of the cytokinin (benzyl adenine, BA) and the auxin (Naphthalene acetic acid, NAA) on the regeneration of shoots from callus tolerant to pollutants reached 76, 87 and 85% for callus tolerant to Cadmium, Lead and sodium chloride respectively, when the combination of 0.7 mg/l BA and 0.2 mg /l NAA was supplemented to the medium. The effect of indole butyric acid (IBA) on rooting of shoots. The concentration 0.7 mg /l gave highest percentage of rooting amounted to 66, 70 and 85% in a medium supplemented with cadmium, lead and sodium chloride respectively. Acclimatization of plantlets using river sand soil recorded 85% survival. The study was also included effects on plant height and fresh weights, shoot fresh weight was superior at the concentration 1.0 and 2.0 mg/l of cd and pb recording 8.7 and 7.5 g respectively. Treatment with NaCl led to increase the root fresh weight recording 19.1 g. Maximum cd accumulation reached 12.5 ppm in shoots, 10.5 ppm for lead in roots, 39 ppm for NaCl in roots. The experimental work investigated the effect of mycorrhiza (Glomus mosseae) on cd, pb and NaCl removal by Sesbania plant when grown in either soil contaminated with cd, pb and NaCl or non - contaminated soil (control). Inoculation with mycorrhiza led to an increase in seed germination percentage (96%), plant height (28 cm) in non - contaminated soil, while achieved an increase in shoot and root fresh weight recording 10.0 and 6.8 g respectively. Inoculation with mycorrhiza also led to a significant increase in cd and pb accumulation in roots reached 9.0 and 87.4 ppm respectively. Meanwhile, Mycorrhiza caused a significant increase in Na accumulation in root system (42.5 ppm) which already affected K concentration as a result of competition with Na recording 16.5 ppm in shoots. Mycorrhiza inoculation led to a significant increase in number of root nodes in non - contaminated soil recording 86%. Finally, mycorrhiza succeded in infecting Sesbania rostrata roots reached 90% in non - contaminated soil while it was 85% in contaminated soil

The study consisted of the investigation about Hepatitis B virus in the saliva as compared with serum by using the ELISA and Real Time PCR techniques as well as the detection about antigens and antibody to this virus in serum. It also seeks about the liver functions enzymes and evaluating the extent of its importance for diagnosing liver disease resulted that virus. However, the obtained results showed that HBsAg antigen was found in 99.4% and (1.101± 0.335) mean ±SD in serum as compared with 48.6% in saliva with a (0.330±0.278) mean ±SD, that gave a noticeable increase when comparing it with the control group which was (0.0039± 0.0024) and (0.0017±0.0014 ) for serum and saliva respectively. The value of T test for serum and control group was (16.25) , while the value of T test for saliva and control group was (4.18). The proportion of correlation between saliva and serum in ELISA test was equal to (0.361) with high significance of test while the value of T test for them was (28.902) with high significance of test. The results have also stated that the age groups involved in the experiment contributed as being high proportion of infection in the serum, but in the saliva, these proportions were different and it has been found that the high proportion of infection was 53.3% in the group (10 - 20) yrs., While the lowest proportion was 38.4% in the (31 - 40) yrs. Moreover, it has been concluded that the number of males exceeded the number of females, but the number of females was the most infected with HBsAg in the experiment group. However, the total number of males was 91, It was found that 90 males have positive test to the HBsAg in serum with a proportion equals 98.9% whiles 42 males have a positive test to the HBsAg in saliva with a proportion equals 46.1%. on contrary, the number of female was 84 female and all of them had a positive test to the HBsAg in serum with a proportion 100% and 43 females have a positive test to the HBsAg in the saliva with 51.1 % as compared with control group which included 15 males and 10 female. All of them were negative to the HBsAg test in serum and saliva... The levels of HBV DNA were determined in the samples of positive saliva to ELISA test by using Real Time PCR. 95% from tested serum samples were positive to the viral load While in saliva 50% from the samples was HBV DNA positive. The results also showed that soluble antigen HBeAg has been detected in 24 patients with 13.7% from a total 175 patient as compared with the control group that showed a negative result to this antigen. As for the antibodies, it has been found that anti - HBc IgM was found in only 5 patients with 2.5% while anti - HBc IgG was found in 170 patients with 97.2% from the total number of patients. The control group revealed negative result for these two antibodies. The anti - HBeAg was in 150 patients with 85.7% from the total number of patients. There were no positive patients to this antibody in control group. The anti - HBs wasn’t found in any patient but it was found in the half of control group. This emphasizes to immunize against HBV in those members. The results also exposed that there was a noticeable increase in liver enzymes that it was found that ALT the elevated levels of were found in 76% of patients. As compared with the control group which has normal values 100%. As for AST enzyme was elevated in 60.6%, As compared with the control group which was normal 100%.It has been observed that ALP enzyme was elevated with a 38.4% in the experiment patients as compared with the control group which was normal 100%. Finally, the total values of TSB was elevated in 35.5%, As compared with control group which was normal 100% with (0.52±0.19). Nevertheless, it has been noticed that it cannot be judged about the person's blood on the basis that it is healthy in case of absence of surface antigen unless it is certain that his/her blood is free from HBV DNA by using the technique of Real Time PCR - since many patients who heal from past infection or their infection in a time of passive and amounts of HBV DNA can't be diagnosed by using the ELISA technique

Abstract: تضمنت الدراسة الحالية عزل وتشخيص (19) نوع من السيانوبكتريا من عينات مياه وتربة طينية ومن الصخور من (5) خمسة مواقع في مدينة تكريت ضمن محافظة صلاح الدين، وقد تم اختيار ثلاثة انواع من هذه السيانوبكتريا وهي : Anabaena oryzae, Nostoc linckia, Anabaena laxa اعتم | The current study included Isolation and Identification of (19) species of cyanobacteria from water, clay soil and rocks samples, collected from (5) sites in Tikrit, salah Al - den province. Three species were chosen each species represent the environment which collected from it. These species were Anabaena oryzae, Nostoc linckia, Anabaena laxa. The effects of some environment factors on growth and biological products quantity has been studied in the three species above. The effects of the temperature showed that 26°C was the best for growth and biological products quantity than 16°C and 36°C. While the pH effects showed that pH 7.6 was the best for growth and biological products quantity than pH 6.6, 8.6. Three light intensities were used 1250, 2500, 5000 lux were used. The results showed that the light intensity of 2500 lux was the best for daily growth and quantity of extracted biological products. While the study of the effects of addition of macronutrient and micronutrient to Asm - 1 media which used for culturing of the three species of cyanobacteria by replacement of NaCl by NaNO3 in the medium, showed that there is an increase in daily growth and quantity of extracts of biological extracts, also the addition of FeSO4.7H2O and NaNO3 together showed further increase of daily growth and biological extracts quantity. The biological products has been identificated by HPLC - MS, IR and NMR. The results showed the presence of the neurotoxin Anatoxin - a and the hepatic toxin Microcystin in its various forms MCYST - LAba, MCYST - YM(O), [D - Asp3, Dha7]MCYST - LR and MCYST - YA in the biological products of Anabaena oryzae. The results also showed the presence of the hepatic toxin MCYST - YM(O) and [D - Asp3, Dha7]MCYST - LR in the extracts of the two spices of cyanobacteria Nostoc linckia and Anabaena laxa.The results also showed that the Muller Hinton Agar media is better than the Blood Agar media in testing the activity of these extracts in inhibition of the pathogenic bacteria, the method of holes is better than saturated discs, and the solvent DMSO (Di - Methyl Sulpho Oxide) is the better in testing of biological activities, while the filtrate of cyanobacteria did not shown any activity for inhibition of the pathogenic bacteria which include : Escherichia coli, Streptococcus pyogenes, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus Vulgaris, Staphylococcus aureus. The results showed the high capability of inhibition in concentrations of 1000, 2000, 3000 µg/ml of the extracts of the cyanobacteria Anabaena oryzae, Nostoc linckia and Anabaena laxa on the above pathogenic bacteria and some times more efficient than antibiotics used for comparison, and the concentration 3000 µg/ml was the most effective.The effects of biological extracts of the three species in concentrations of (1000, 2000, 3000) µg/kg of body weight on tested albino mice, using injection and feeding methods, was studied. The results showed poisoning nervous symptom for the first few hours, while the results showed hepatic poisoning symptom on the dissecting animals. The anatomic symptoms included changes the colour of the liver to darkening and appearance of necrosis, in addition to becoming lobbed and swollen some times with bleeding.While the poisoning effects on dissecting tissues of livers of the animals showed a simple swollen and some times assured in all of the liver accompanying with increase in growth and cell division, as well as increases in lymphatic cells inside the tissue and in general in liver tissue. The lymphocyte seemed bigger than for normal cell with multi - nuclei in white blood and increase in cell size and destruction of liver tissue. Nostoc linckia was the greater urging for cell division consequently probably more induce of cancer in the liver of the animals, while the biological product of Anabaena laxa showed more poisonous for liver cell than the biological products of Anabaena oryzae, the least effective in cytotoxic and urging cancer cell in liver of the animals.

Abstract: A total of 359 samples divided as 228 clinical and 131 non clinical specimens were collected during 2012 from four hospitals in Baghdad city including : Al - Kadhymia Teaching hospital, Baghdad Teaching hospital, The Burn Specialist Hospital and Al - Imam Ali hospital, for isolation of P.aeruginosa to study the correlation between collagenase production and biofilm formation. Eighty two Pseudomonas isolates were screened for biofilm formation, 28 isolates were classified as strong biofilm formers, 25 as moderate and 27 as weak biofilm former. The 28 isolates were identifid by VITEk - 2 Compact system which confirmed that the isolates were P.aeruginosa. Collagenase production assay was used to screen 28 isolates that were strong biofilm formers inorder to detect the ability of these isolates to produce collagenase, the substrate of collagenase (collagen) was purified localy from bovin tendon and the results showed that just 8 isolates could grow in mineral salt media with collagen after 4 days of incubation. The factors affecting biofilm formation and collagenase production were studied to determine the optimual conditions for their production, those factors included : 1 - Nitrogen sources represented higher influence on collagenase production specialy (yeast extract) in media containing collagen than other media without collagen as a substrate. The specific activity differed between the 8 isolates, biofilm formation also became more pronounced with (yeast extract), while NH4Cl and NaNO3 depressed biofilm formation at the same conditions. The statistical analysis between the two parameters (biofilm and collagenase) according to different nitrogen sources demonstrated highly significance at p?0.01 with yeast extract and casein. 2 - pH, results showed that the best pH for production was 7 for both collagenase and biofilm.The statistical analysis for determination the relationshipe between the two parameters showed highly significance at p ?0.01 for different pH. 3 - The maximum production of the two parameters was at 35?C temperature which gave highly significance at p?0.01 with defferent temperature. 4 - Long incubation periods revealed increasing in collagenase production and biofilm formation which represented highly significance detween them when incubation periods were prolonged at p?0.01. Results of this study showed that collagenase production increases when bacteria switch from a planktonic to biofilm phenotype. This indicates that biofilms and collagenase are more virulent and have a greater ability to cause tissue destruction. The REP - PCR analysis using BOX - primer, showed a clusters genetic relatedness among the isolates. The isolates were grouped according to the REP - PCR in 9 different genotypes, named cluster 1 to 3 which included C1, C2, C3 with relatedness : 8 (80%), 8 (86%), 3 (80%) respectively. A19 and A20 both of them were not included in any cluster, they have 78% similarity.The REP - PCR analysis showed that the genotypic relatedness is consistently high between the 8 producer isolates and non producer isolates (13), showed similarity reached 86

Abstract: توضح هذه الدراسة عزل lipA gene من الزوائف الزنجارية من مياه الصرف الصناعية للزيوت النباتية وتشخيصها اعتمادا على تفاعل البلمرة المتسلسل (PCR). استغرقت هذه الدراسة تسعة اشهر, من شهر شرين الاول 2014 لغاية حزيران 2015. تم جمع خمسين عينة من مياه الصرف الصناع | This study clarify the isolation and identification of lipA gene in Pseudomonas aeruginosa from industerial wastewater of vegetable oils factories depending on the polymerase chain reaction (PCR) technique. The present study had taken nine monthes starting from October 2014, till the mid of June 2015. Fifty samples of industrial wastewater were collected from the factories of the general company of vegetable oils, fourty from AL Rasheed factory and ten from AL ameen factory, the samples collected from the physical, chemical and biological treatment units, and other different wastewater tanks departments. While the four sewage samples were collected from sewer service Baghdad /Alrustumaiya. For Identification of Pseudomonas aeruginosa, two types of tests were used in this study. The first type was the routine tests, which include selective cultures, bacteriological and biochemical tests. Thirty four of fifty samples (68%) gave a positive growth and results for tests that were used to confirm the presence of P. aeruginosa. In addition to diagnosis P. aeruginosa in sewage sample which prepare the biological treatment units in vegetable oils factories as active sludge, other bacterial types have been diagnosed by using traditional methods and API 20 E system. For detection of bacterial lipolytic activity, two methods were used for this purpose, the first was the screening of bacterial lipolytic activity which was based on values of clear zones diameter around bacterial colony. The best values were between (1.9 _ 2.7) cm. The second test was carried by the Gas - Chromatography - Flame ionization detector, fatty acids solutions that were produced from hydrolysis by lipase enzyme were extracted by Petrolium ether solvent then analyzed by gas chromatograph apparatus. The second type of test was the Molecular diagnosis by using the Polymerase Chain Reaction (PCR) to detect lipA gene in Pseudomonas aeruginosa by two primers. Through two primers used, lipA 948 was the best and more specialized primer to isolation lipA gene of P. aeruginosa. It gave (100%) a positive result. While the second primer lipA 558, gave (66.66%) a positive result and that may be due to the design of this oligonucleotides was not specific for lipA of P.aeruginosa. This is so as was based on highly preserved region of 12 bacterial lipA - homologous genes for many genus and many species belong to Pseudomonas. DNA sequencing done for amplicon generated using lipA 948, this sequence aligned by using BLASTn software against NCBI database to validate the results and investigate the similarity degree with other corresponding strains.

Abstract: Three experiments were conducted on two cultivars of sweet pepper Capsicum annuum L.; Flavio F1 and California wonder, to study the effect of seaweed extract and amino acids mixture and their combination on some vegetative and reproductive parameters, and some physical and qualitative characters of fruits. In addition, the chemical composition of leaves and some anatomical characters of stems were also evaluated. Furthermore, the effect of some treatments on genetic variations in both cultivars were studied. The field experiments were carried out at the fields the College of Agriculture/Al - Qadisiya University. The experiment was started at 18 - 1 - 2013 and ended at 3 - 7 - 2013. Seaweed extract, Basfoliar Kelp SL, was used at two concentrations; 3 or 6 ml. L - 1 in addition to control treatment (distilled water only). Also, a mixture of amino acids was used at two concentrations; 400 or 800 mg. L - 1 in addition to control treatment. Spray with the two substances was done in the early morning. The treatments were designed as a factorial experiment with two factors (3X3) in a randomized complete block design with four replications. The vegetative characters measured included; plant height, number of branches, percent of dry weight of shoot and root, and leaf chlorophyll content. Also, nitrogen percent, phosphorus and potassium content in leaves and roots was determined. The flowering and yield characters included; total number of flowers per plant, fruit set percentage, and total fruit yield per plant. In addition, weight, size, diameter and fruit length were measured. Vitamin C, total phenols, TSS, total sugars, alkaloids percent and the capsicin were measured in fruit juice. The anatomical characters of plant stem were included; epidermis, cortex and vascular bundles thickness, diameter of vascular units and pith thickness. The laboratory experiment was carried out during the period from 2 - 9 - 2013 till 16 - 10 - 2013. Spray with the two substances and their combination, at the same concentrations as used in the field experiment, was done on plants at the true leaves stage. The experiment was design as a factorial experiment with two factors in completely randomized design with four replications. The chemical characters measured in leaves included; content of auxin and gibberellin like substances, activity of catalase and peroxidase enzymes, amino acid content in addition to protein and sugar percent. Also, the genetic variation and genetic distance degree due to some treatments compared to control treatment using the RAPD with five primers was studied. The results were as the following : 1. Using seaweed extract and amino acids mixture, especially at the higher concentration, caused a significant increase in all vegetative characters measured for the two cultivars. 2. There were a pronounced increase in nitrogen percentage in plant shoot and root as the concentration of the treatments increased in both cultivars. 3. Increasing the concentration of the two factors caused an increase in phosphorus content in plant shoot of both cultivars. In roots, the use of the higher concentration of seaweed extract increased phosphorus content in Flavio F1 cultivar only. on the other hand, there was no significant effect on the mineral content in California wonder cultivar. Also, there was no significant effect on the phosphorus content in both cultivars due to the use of the two concentrations of amino acids and the combination of the two factors. 4. The use of seaweed extract caused a significant increase in potassium content in the shoots of the two cultivars. Also, the two concentrations of the amino acids caused an increase in the mineral content in shoots of the Flavio F1 cultivar only, while there was no effect in the California wonder cultivar. In roots, there was a significant effect due to the use of seaweed extract on potassium content, while there was no effect due to the use of the amino acids in Flavio F1 cultivar. In California wonder cultivar, no significant increase in potassium content was recarded in roots due to the use of all concentrations. 5. Seaweed extract and amino acids extract concentrations caused significant increase in total flowers number, fruit set, number of fruits per plant, plant yield and the physical characters of fruits, where the higher concentration of the two substances used gave highest values of fruit diameter, weight and size in both cultivars. Fruit length was not affected in Flavio F1 cultivar only. 6. The use of the two substances caused pronounced increase in TSS, sugars, vitamin C and phenols in the fruit of the two cultivars. Also, The use of seaweed extract had no effect on total alkaloids in Flavio F1 cultivar. While the amino acids mixture at the two concentrations increased alkaloids percent in fruit of the two cultivars. Also, there was a clear increase in the active ingredient (capsicin alkaloid) as the concentrations of the two substances used increase. 7. Both substances increased the auxin like substances in leaves of the two cultivars. The gibberelline like substances did not affect due to the use of seaweed extract of either cultivars. Amino acids had no significant effect. 8. The use of seaweed extract and amino acids mixture and their combination caused a significant increase in catalase and peroxidase activity in leaves, except the activity of peroxidase in leaves of California wonder cultivar which not affected by the seaweed extract. 9.Total free amino acids content and protein percent increased as the concentration of the two factors increased. Also, seaweed extract had significant effect on the percent of the total sugar. Amino acids treatments had no effect on sugar percent. 10.Using seaweed extract or amino acids caused an increase in epidermis and cortex thickness and size of vascular bundles of stem of both cultivars. 11.The use of seaweed extract, especially at the higher concentration, had significant effect in increasing the diameter of vascular units, while there was no effect due to the use of the amino acids. 12.There was a negative effect of the seaweed extract on pith thickness due to the use of the seaweed extract. on the other hands, the amino acids treatments caused an increase in stem pith. 13.The combination between seaweed extract and amino acids treatment had significant effect on most of the morphological, physiological and anatomical characters studied for both cultivars. 14.Increasing concentrations of seaweed extract and amino acids mixture or their combination caused an increase in DNA and RNA content in leaves of the two cultivars. The increase was greater at the higher concentration of both substances used. 15. Treatment with some concentrations of seaweed extract and amino acids and their combination produced plants with genetic variation as compared to the control plant using RAPD technology with five primers. The variation ranged from 13.04% using OPB - 9 primer to 33.33% using OPB - 4 and OPB - 11 primers in Flavio F1 cultivar. In California wonder cultivar, the variation ranged from 4.35% using OPB - 14 primer to 73.33% using OPB - 5 primer.

Abstract: تعد الاصابة ببعض العوامل المرضية مسؤولة عن حوالي خمس حالات السرطان في العالم. وهنالك العديد من الاصابات الطفيلية التي ثبت دورها كمسبب او محفز لسرطانات معينة، الا ان العلاقة بين الاصابة بالاكياس المائية والسرطان مازالت موضع جدال ولذلك فقد هدفت الدراسة الح | Infectious agents are responsible for about one fifth of all cancer cases worldwide. Some parasitic infections are well documented to cause certain cancers. However, the association of hydatid cyst (HC) with cancer is a controversial issue. The current study aimed to investigate the possible association between chronic hydatid cyst infection with liver and lung cancers. The study involved three groups : the first group included 42 patients with HC, the second group included 35 patients with liver (12) and lung (23) cancers, while 25 apparently healthy individuals were recruited to represent the third group (control). Number, diameter, location and the status (calcified or non - calcified) of the HC were recorded from HC group. Blood samples were collected from the studied groups from which serum were separated and kept until being used. Enzyme linked immune - sorbent assay (ELISA) was used to estimate serum levels of anti - HC IgG antibodies, carbohydrate antigen (CA19 - 9), alkaline phosphatase (ALP) and ? - glutaml transferase (GGT), while Absorbance measured by spectrophotometric method was used to determine levels of lactate dehydrogenase (LDH) and adenosine deamimase (ADA).All members of HC group gave positive result for anti - HC IgG antibodies compared to 11 patients from cancer group and oneindividual from control group (Odds ratio =8.3). Both HC and cancer groups showed significantly higher p<0.05 levels of CA19 - 9, ALP, LDH and GGT ((76.16±58.26 U/ml and 110.77±96.47 U/ml), (131.81±76.65 U/L and 141.72±97.23 U/L), (244.24±117.94 U/L and 254.68± 115.56 U/L) and (95.06±66.73 U/L and 105.12± 41.42 U/L) respectively) than control group (10.81± 9.12 U/ml, 65.14± 25.21 U/L, 146.15± 37.59 U/L and 17.21± 6.87 U/L respectively). In cancer group, casp - 8 level (72.20±54.72 picomol/ L) was significantly lower from than that of control group (92.30± 41.20 picomol/L) and insignificantly from that of HC group (60.86±40.84 picomol/L). In HC group, ADA level was 47.84±10.65 U/L and was significantly higher p<0.05 than that of cancer group (10.14± 1.99 U/L) and control (16.09±2.70 U/L).Investigation for the risk factors which may increase the risk of developing liver or lung cancers in HC patients revealed that male, smokers and rural residents were more susceptible for such development (Odds ratios : 3.45, 6.982 and 5.48, respectively). Number and cyst size were significantly correlated with the level of anti - HC IgG antibodies (r= 0.539, P<0.001 and r= 0.618, P< 0.001 respectively), while calcified cysts associated with significantly higher levels p<0.05 of CA19 - 9 and GGT (105.03±88.9 U/ml and 145.46±101.57 U/L, respectively) than that of non - calcified cysts(65.91±39.87 U/ml and 77.17±7.23 U/L, respectively). Average level of anti - HC IgG antibobodies in calcified cysts was 19.75±13.11U/ml and was significantly P<0.05 lower than its counterpart of non - calcified cysts (85.017±76.84 U/ml). All studied parameters showed significantly higher levels in livers cysts than their counterparts in lung cysts. Results of the current study indicate that chronic infection with HC can increase the host susceptibility to develop liver or lung cancer.

The results also revealed a decline in the average body weights on the period of 7 and 21 days of treatment when compared with the weight of the same animals before treatment and the decline was significantly at (P<0.05). Whereas the testes and tunica albuginea weights recorded a significant decrease in their average weights (P<0.05) when compared with control groups. As well as the epididymis weights where showed significantly decrease (P<0.05) in the average of the epididymides heads weights for all three periods of treatment, while a significant decrease (P<0.05) in the average weight of the epididymis tail appear for two periods 7 and 21 days compared with control groups. The study also reported a decrease in the percentage of live sperm and the average sperm concentration and an increase in the percentage of sperm abnormalities extended to all periods of treatment compared with control groups and this change was significant at the level of (P<0.05). The number of leydig cells and nuclei diameters, the results show a decrease in their averages and all the extended treatment period when compared with control groups, and this decrease was significantly at (P<0.05). Treatment with particles of copper nanoparticle indicated a decrease in the percentage of spermatogonia, primary spermatocytes and sperms in all periods of treatment compared with control groups and this decrease was significantly at the level of (P<0.05). While the results of the study revealed a significant increase at the level of (P<0.05) in the percentage of secondary spermatocytes and spermatids compared with the control animals. The study also showed a significant decrease at the level of (P<0.05) in the diameter of the seminiferous tubules of testes and the wall thickness of the seminiferous tubules for all periods of treatment compared with control groups. As well as a reduction in wall thickness and height of the epithelium in epididymis (head and tail) for all periods of treatment compared with control animals and this decline was significantly at (P<0.05). The current study also recorded a textile damage in the testes and epididymis (head and tail), which summarized the crash of some seminiferous tubules, degeneration of lining cells in tubule, the appearance of vacuole between cells and lifting epithelium from the basement membrane. On this basis, this study has shown for the first time that particles of copper nanoparticles have a negative impact on the effectiveness and activity of the male reproductive system in albino mice.

These taxa included : Citrullus colocynthis Schrad, Citrullus vulgaris Schrad, Cucumis melo Linnaeus, Cucumis melo var.flexuosus Naudin, Cucumis sativus Linnaeus, Cucurbita maxima Duchesne, Cucurbita pepo Linnaeus, Lagenaria siceraria (Mol.) Standl, Luffa cylindrica (Linnaeus) M. Roem. This study focused on some the anatomical characterization as compared study for the first time to these taxa in Iraq. This study included the features of ordinary epidermal cells, leaves petioles, stems, pedicles and sepals of the studied taxa. The results found the appearance of stomata in the stems and petioles in straight line as adjacent planar shape to the epidermal cells and not scattered as found in the leaves, this result was seen for the first time in the current taxa. Furthermore, the stomata have been shown in pedicel and sepals in same type as the stomatal complexes in leaves. The importance of phenotypic variation for the length and types of eglandular trichomes and the presence or not of glandular trichomes were found to carry out the role of indumentum in the different isolated taxa. Additionally, this study included the examination of the cross sections of the roots and also exposed the constituent tissues of it, the variation in the thickness of epidermis, cortex, vascular cambium as well as the arrangement of phloem cells have an important role in the studied taxa. The cross sections of stems, leaves petioles and pedicles showed shape and studied a significant role in the studied taxa and split them into groups.Moreover, this study concluded that the following of above sections from the outside into the inside has an important role to find out their constituent tissue. Thus the results of the study clarified the importance of epidermis tissue through the explanation of the outer and inner tangential walls of their cells and the variation in their dimensions, thickness and kind of stomatal complexes; therefore it has been given the importance of those features in the studied taxa in this study. Cortex tissue showed an extension of angular collenchyma and chloronechyma from stem to pedicel and have shown variation in the thickness in these two layers which was useful in the classification of studied taxa. Vascular tissues differed in the shape of vascular bundle, the number of rows and xylem units and the arrangement of the internal phloem, and all of those characteristics have helped in the studied taxa. In addition, the vascular tissues helped to find their arranged in the stems and found as vascular cylinder shape, while in the petioles and pedicel shown as vascular ribbons were which took the shape of sections petioles and pedicel. The medullar cells and medullary rays have been studied and also their similarity in the morphological characterization and function. Moreover, the anatomical features of the vertical sections of the laminae of leaves in mesophyll tissue have been examined, in the thickness of palaside and spongy layers in midrib, the variation in number and arrangement of vascular bundles have an important role in the studied taxa. In the current study, the ordinary and petal leaves venation and the type of venation have been studied in the studied taxa. Moreover the vertical sections for sepals were examined and also their similarity with laminae of leaves which was useful for studying the constituent tissues of some parts such as pedicel and sepals and anatomical features; and all of the studied characterization helped to study the vegetative parts through following them in studied taxa.

Abstract: Polycystic ovary syndrome is the most common endocrinopathy in women, affecting 5 - 10% of women of reproductive age.The principal features of PCOS are anovulation, resulting in irregular menstruation, amenorrhea, ovulation - related infertility, and polycystic ovaries; excessive amounts or effects of androgenic hormones. Leptin, a key hormone in energy homeostasis and neuroendocrine function, has a permissive role in the pathogenesis of reproductive dysfunction. Aim of the study To assess the role of serum leptin in women with PCOS and to evaluate leptin levels in PCOS women before and after treatment with metformin. Materials and Methods This prospective experimental study included 60 women of reproductive age (18 - 38years) were allocated to four groups : 15 obese women with PCOS (BMI >30 kg/m2), 15obese controls, 15 non - obese women with PCOS (BMI 18 - 30 kg/m2), and 15 non - obese controls. Serum leptin and insulin levels were measured and compared between case and control subjects also comparison done before and after treatment with metformin. Results There was a significant increase in leptin in non - obese PCOS group (8.2±2.73) compared to non - obese control (5.64±1.43), (P value=0.0032), insulin level was significantly higher in PCOS group (15.87±6.65) than control (5.47±1.68), (P value<0.001). There was significant decrease in BMI, leptin and insulin levels after 12 weeks of metformin treatment in obese and non - obese PCOS subjects. Conclusions Leptin level increased remarkably with increasing body weight. It is higher in non - obese PCOS women in comparison with non - obese healthy women. Treatment with metformin for 12 weeks resulted in significant reduction in leptin levels in both obese and non - obese PCOS subjects.

Abstract: تسلط الدراسة الحالية الضوء على تشخيص وتحديد نسبة الاصابة بطفيلي الاميبا المرضية المتمثلة بالاميبا الحالة للنسج Entamoeba histolytica وتمييزها عن الاميبا غير المرضية المتمثلة بالاميبا المتغايرة Entamoeba dispar اللتين تتمايزان بشكلهما المتماثل في كلا الطور | This study sheds light on the determination and diagnose of the percentage of infection of like Entamoeba histolytica and differentiate it from the non pathogenic Entamoeba dispar that were morphologically identical in both cysts and trophozoite phase in two different groups : the first group includes 50 stool samples of patients suffering from diarrhea and abdominal pain (symptomatic group) while the second group includes 95 stool samples of patients not suffering from diarrhea and abdominal pain (Asymptomatic group).In addition to that, 20 stool samples were collected from healthy individuals as a control these samples were collected patients of AL - Zafaranyia General Hospital and AL - Alwyia Childhood Teaching Hospital in Baghdad from July, 2011 to May, 2012.These samples belong to different ages (1 year - < 50 years) of different sexes (males and females). Entamoeba samples were diagnosed by using two methods : the first one is the wet mount as a General Stool Examination(GSE) after macroscopic examination for sample and classifying them according to their consistency (solid, semisolid and liquid) and color (brown and yellow) and presence of blood and mucous in addition to diagnosing them microscopically to detect the presence of pus cells and both phases trophozoite and cyst for Entamoeba histolytica.While the second method that was depended in diagnosis is duplex polymerase chain reaction (dPCR) by using two pairs of genes for detection of their amplification in DNA sample isolated from stool. The first pair is cystein proteinase which represents one of virulent factors in Entamoeba histolytica parasite as a tissue invader. The second pair encodes the surface antigen present on the surfaces of both parasites E. histolytica and E. dispar. It is represented by Actin gene (Act). The results of the wet mount showed that in percentage of infection of both species (E.histolytica/E.dispar) the (54%) of patient symptom and (34.37%) patient a symptom.While results of the specificity and sensitivity showed that in positive sample wet mount negative PCR while negative sample wet mount showed that positive PCR and higher percentage of infection the Entamoeba dispar. While the results of the dPCR showed that in spite of the presence of both species Entamoeba pathogenic (Entamoeba histolytica) and non pathogenic Entamoeba (Entamoeba dispar) , the percentage of infection of Entamoeba histolytica was lower than that of Entamoeba dispar. This was clear by the detection of amplification the Reaction producets (dPCR) by using both genes : Actin &Ehcp5 where only 8 samples were detected and they were found to be positive amplification Ehcp5 and 31 samples were positive amplification in both groups of patients (symptomatic and a symptomatic). The percentage of infection in females was higher than that in males for all ages when using both tests (wet mount & PCR). More over the patients with less than (10) years old had higher percentage of infection in both sexes.In conclusion, it should not be depended on direct wet mount technique for the identification of infected parasite Entamoeba histolytica and differentiating it from Entamoeba dispar because of their high homology. That the molecular examination is the only method that is able to determine the kind of infection with parasite Entamoeba

Abstract: انقطاع الطمث لاسباب ثانوية هو انعدام الدوره الشهريه لمدة ثلاثة الى ستة اشهر للنساء اللواتي لهن دوره شهريه منتظمة.واستنادا لمنظمة الصحة العالمية ان انقطاع الطمث يتضمن مجموعة (WHOI) و(WHOII) والتي تكون (30%) من حالات العقم.وتعاني اكثر النساء ممن يكونون من م | Secondary amenorrhea refers to the lack of cycle for three months in a row or for more than six months in a woman who has had regular menstrual periods before, and its associated with conditions classified as World Health Organization (WHO) group 1 and WHO group 2 and has been estimated to represent almost (30%) of all causes of infertility. In clinical practice, WHO group 2 subjects present much more frequently than WHO group 1 subjects and they appear to be much harder to treat successfully. Among women classified as WHO group 2, those diagnosed with polycystic ovary syndrome (PCOS) constitute the largest group (60 - 85% of cases). These women account for most cases with oligomenorrhea (90%) and represent about (30%) of those with amenorrhea.ObjectiveThe aim of this study was to find out the pregnancy rate following intrauterine insemination (IUI) in women complaining of secondary amenorrhea after induction of ovulation and compare it with those achieve pregnancy by natural way.Material and MethodsSeventy five females with secondary amenorrhea were involved in this study, there ages were ranged between (?30, 30 - 39, ?40) years old with infertility duration ranged between (?2, 3 - 4, 5 - 6, 7 - 8, ?9) years. History and medical examination were done for all women, with tubal patency assessment by HSG or laparoscopy.By cycle day two, hormonal assay (S.FSH, S.LH, S.E2, S.Prolactin and S.Testosterone) were done for all females in addition to ultrasonography to exclude any ovarian pathology.Ovulation induction program was applied for all females which include either clomiphene citrate (CC) alone, recombinant Follicular Stimulating Hormone (r - FSH) alone or combined CC and r - FSH. Vaginal ultrasonography was done for all females on day 12 or13 to assess ovarian response (size and number of mature follicles) and endometrial thickness. Meantime all male partners undergo seminal analysis to assess sperm parameters (sperm concentration, sperm motility and morphology).Thirty eight of females participated for natural pregnancy and thirty seven of females participate for IUI. Washing swim up technique was used for sperm activation for all male partner involved in IUI group.Follow up of all these females for pregnancy test to assess the pregnancy rate for both groups (natural and IUI).ResultsThe pregnancy rate achieved by natural way for a women with secondary amenorrhea is (23.7%), and (18.92%) by IUI way.In this study, it was found that female age, infertility duration, hormonal balance and ovulation induction program affect the pregnancy outcome where the young age group and short infertility duration correlate positively with pregnancy rate. Furthermore, early diagnosis of underlying causes of secondary amenorrhea to achieve hormonal balance by suitable ovulation induction program, have an effect on pregnancy rate, were combined CC and r - FSH produce a significant result among females achieve pregnancy by natural way (13.5%) compared with other ways. While ovulation induction by r - FSH drugs produce a significant results (13.5%) among females achieve pregnancy by IUI way.ConclusionFrom results of this study, it was concluded that young female age, short infertility duration, early diagnosis of underlying causes of secondary amenorrhea and the use of r - FSH drugs for ovulation induction produce a high significant pregnancy rate using IUI program.

Seventy four isolates of Streptomyces were screened for cellulase production in solid and liquid media. The results showed higher capability of isolate Streptomyces sp. B 167 for cellulase production and bioconversion of cellulose. Therefore, it was selected for further studies. The results of optimization revealed that the cellulase enzyme productivity by the isolate Streptomyces sp. B 167 reached to 2.1 and 2.28 U/ml after 48 h of incubation time and pH 7 respectively. Cellulase productions in tested isolate improved (2.57 U/ml) by supplementation of cellulose liquid medium with 1 % of yeast extract as nitrogen source. Additives of carbon sources like (manitol, glucose, maltose, sucrose and starch) to the process of saccharification did not improve the cellulase productivity. The bioconversion of cellulosic waste to reducing sugar was maximum with Banana peels (77.78 %) followed by the rice husk (75.56 %), orange peels (71.11 %), corn steep peels (60.0 %) and lowest bioconversions (53.33 %) were recorded with sawdust. The degradation of cellulosic waste increased with increasing substrate concentration. Maximum cellulase productivity (3.18 U/ml) and bioconversion (86.1 %) was obtained at 3 % (w/v) of cellulosic waste (Banana peels). Saccharification of cellulosic waste with different treatment methods was studied. The pretreatment of cellulosic waste with 1 % HCl and H2SO4 produces 21 and 15.8 g of reducing sugar / 100 g of cellulosic waste. In comparison, hydrolysis with Streptomyces sp. B 167 enzymes resulted a significantly higher amount of reducing sugar yield (25 g / 100 g cellulosic waste). Further fermentation of cellulosic hydrolysates was performed using Saccharomyces cerevisiae using stationary fermentation condition. Maximum yield of ethanol were (0.30, 0.19 and 0.10 g ethanol / g glucose) observed with Streptomyces sp. B 167 enzymes, HCl and H2SO4 hydrolysates respectively after 48 h of fermentation

Abstract: جمعت (140) عينة من المرضى الراقدين لثلاثة ايام فاكثر في مستشفى تكريت التعليمي للمدة من 1 - 8 - 2009 ولغاية 1 - 12 - 2009 بهدف تحديد العزلات الجرثومية الاكثر شيوعا ضمن اخماج مستشفى تكريت التعليمي ومقاومة هذه العزلات للمضادات الحيوية ودراسة العلاقة بين مقاو | One hundred fourti samples were collected from hospitalized patients for three days or more in the Tikrit Teaching Hospital during the period from 1/8/2009 until 1/12/2009 to determine the most commonly isolated bacterial from nosocomial infections in Tikrit Teaching Hospital and their resistance to antibiotics and to study the relationship between antibiotics resistance and plasmid content in the most commonly isolated bacteria and to evaluate the prevalence of these plasmids in the hospital environment. These samples include : (75) Urine, (28) stool, (28) of wound swabs and (9) sputum samples.The incidence of nosocomial infection was (45.7%) of them, urinary tract infections were (50.7%) from (75) samples, followed by wound infections (42.9%) from (28) samples, gastrointestinal infections (39.3%) from (28) samples then pneumonia (33.3%) from (9) samples the nosocomial infections were more common in females and age group 51 - 89 years. Different bacterial species were isolated in this study and the results showed that the most commonly isolated type was Citrobacter koseri in a proporation (21%) of urinary tract infections, followed by the following bacterial species : Escherichia coli (15.7%), Staphylococcus schleiferi (10.5%) , Staphylococcus epidermidis (7, 8%), Proteus vulgaris, Staphylococcus saprophytica, Klebsiella ozaenae, Klebsiella ornithindytica in aproportion (5.2%) for each, Enterobacter aerogenes, Providencia stuartii, Staphylococcus warneri, Staphylococcus aureus, Proteus mirabilis in aproportion (2.6%) for each.Citro. koseri were also the most common in wound infections (25%), followed by the following bacterial species : E.coli (16.6%), P.mirabilis (16.6%), Staph.schleiferi, P.vulgaris, Prov.stuartii and Prov.rettgeri in aproportion (8.3%) for each. Citro.koseri were also the most common in the gastrointestinal tract infections in a proporation (36.3%), followed by E.coli (18.1%), S.flexneri (18.1%), P.mirabilisc, Prov.stuartii, Prov.alcalifaciens in a proporation (9%) for each. . While Strept.pneumoniae was the most common(66.7%) in penemonia cases followed by K.pneumoniae (33.3%).The isolated bacteria were tested for antibiotics susceptibility and it has been found that most of these isolates showed high resistance to the studied antibiotics other than Prov. Stuartti was sensitive to all antibiotics except of Rifampicin and Tetracycline. As well as bacterial species belonging to the genus Staphylococcus were sensitive to Amikacin, Staph.aureus was also sensitive to Nitrofurantoin while Staph.warneri was also sensitive to Ciprofloxacin and Nitrofurantoin also Enterobacter aerogenes was resistant to all antibiotics except for Ciprofloxacin and Nitrofuratoin. Eleven of most commonly isolated bacteria which were multidrug resistant were chosen for the curing experiments using SDS to study the relationship of their plasmids with resistant to antibiotics. The results showed that the cured cells of E.coli lost their resistance to Tetracycline Ciprofloxacin and Cefotaxime which Citro.koseri lost their resistance to Tetracycline while K. ornithinolytica lost resistance to both antibiotics Tetracycline and Ciprofloxacin either P.mirabilis lost resistance only to tetracyclin as well as Strept.pneumoniae lost their resistance to Cefotaxime, tracycline and Ampicillin. Which may mean that the genes responsible for resistance to these antibiotics are located on plasmids as proven by the results of electrophoresis.Electrophoresis results also showed that all studied bacterial isolates had the same plasmid profile which may regarded as an epidemiological pointer that plasmids are conjugative which have the ability to transfer antibiotic resistance to other bacterial strains of the same species or to other different bacterial species.

These properties were; temperature of the air and water, light penetration, electrical conductivity, salinity, turbidity, water current speed, total suspended and dissolved solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, carbon dioxide, total alkalinity, acidity, total hardness and ions of calcium, magnesium, sodium, potassium, and the sodium adsorption ratio, chlorides, sulfates, boron, nitrite, nitrate, phosphate, silica and some heavy metals such as cadmium, lead, zinc, copper, chromium, manganese in both phases : dissolved and particulate. results showed that the values of the physical and chemical factors ranged as follows : (7 - 47) C, (10 - 31) C, (14 - 177.5) cm, (1020 - 5600) µs/cm, (0.65 - 3.46) 0%, (0.07 - 129) NTU, (27.03 - 115.57) cm/s, (591 - 2985) mg/L and (0.001 - 0.128) mg/L, (7.04 - 8.8), (6 - 11.8) mg/L, (0.13 - 6.6) mg/L, (8.2 - 53) mg/L, (81.4 - 198) mg/L, (30 - 200) mg/L, (6 - 46) mg/L, (490 - 929.67) mg/L, (83.37 - 290.18) mg/L, (0.79 - 174.84) mg/L, (92.5 - 713) mg/L, (1.9 - 11.18) meq/L, (6 - 133) mg/L, (97.97 - 861.73) mg/L, (329 - 1040) mg/L (0.01 - 4.23) mg/L, (0.008 - 1.33) µg/l, (2.16 - 44.74) µg/L, (0.012 - 0.59) µg/L and (104 - 514) µg/L respectively.Concerning the heavy elements, the values of dissolved cadmium ranged between (undetectable - 0.075 mg/L) and it's particulate between (0.0043 - 0.2705) mg /L and dissolved lead between (undetectable - 0.0232 mg /L) and it's particulate between (0.0045 - 0.148) mg/L and dissolved zinc between (un - detectable - 0.0168 mg/L) and it's particulate between (0.0115 - 0.316 mg/L) and dissolved copper (undetectable - 0.0273 mg/L) and copper is particulate between (0.0062 - 0.063 mg /L) and dissolved chromium between (undetectable - 0.0193 mg/L) and the chromium is particulate between (0.0043 - 0.0449) mg/L and dissolved manganese (undetectable - 0.0256) mg/L and it's particulate between (0.0085 - 0.0739) mg/L.The biological tests include Qualitative and Quantitative Study on phytoplankton and also included calculating the total number of coliform way casting dishes by using the MacConkey Agar media.The number of diagnosed species of Phytoplankton was 295 species, belonging to 74 genera. The Diatoms Bacillariophyceae won the biggest part of it as it formed 160 species and 35 genera any rate (54.24%), followed by green algae (70 species belonging to 24 genera) and green algae (52 species belonging to 11 genera) then Euglenophyceae (10 species belonging to both sexes), while golden brown algae and algae Pyrrophyceae were less algal groups registered as belonging to the two single - sex. Some types of phytoplankton existed in most of the duration of the study, including Bacillaria paxillifera, Cocconies placentula, Cyclotella meneghiniana, Diatoma elongatum, Fragilaria virescence, Melosira ambigua, Synedra acus.The total number of phytoplankton is estimated between (104.9 - 4460.09) cell × 103/liter. An increase in the number of phytoplankton in July and January was observed clearly. The concentrations of chlorophyll - a were ranged between (0.0693 - 9.78 mg /L). While the total number of results for coliform were (5 - 281 × 103) cells/liter, The water quality of the evidence Account (Canadian model) using a number of physical, chemical and Biological properties. The results showed that the waters of the Euphrates are located within categories (Poor - Good) with respect to the public evidence of the quality of water of this river while it was located within categories (Poor - Acceptable) with respect to their use for drinking, While its use for irrigation purposes, it was clear that run river water data fall into two categories (Poor - Good). The results of the analysis of the main components Principal component Analysis (PCA) indicate that the nitrates and the total number of coliform and dissolved oxygen, phosphate, zinc, lead and Biological oxygen demand and pH are the biggest impact on the water quality of the index values of the variables of general purpose.These factors are responsible for the deviation index values, followed by turbidity and total hardness and electrical conductivity and temperature of the water, copper, chromium, and cadmium heat. But with the biggest impact of the index water quality factors for drinking purposes are chloride and electrical conductivity and total hardness, magnesium, turbidity and basal college, sodium, calcium, copper, sulfates, nitrates and coliform, zinc and dissolved oxygen, pH, manganese and lead followed by boron nitrite, cadmium, chromium and vital requirement for oxygen. While the chloride and conductivity electrical, the proportion of sodium, copper, zinc and adsorption of boron have greatest influence on the value of water quality index for irrigation, followed by manganese, cadmium, chromium, lead and pH.The phytoplankton index of Biotic Integrity (P - IBI) has been calculated using ten units including (relative abundance of green algae, green algae, pyrrophyta, Euglenophyta, Xanthophyta, Centralales, pennales, species richness index, the density of phytoplankton and chlorophyll a) The results showed that phytoplankton index of Biotic Integrity values ranging between (47 - 74) in the first position and (47 - 67) in the second location, and (45 - 76) in the third site and (45 - 71) in the fourth site. In other words, phytoplankton index of Biotic Integrity with estimating index (good - poor). The results showed the effectiveness of phytoplankton index of Biotic Integrity values in estimating the environmental changes.

Abstract: استخدمت في هذه الدراسة 125 عينة من حديثي الولادة لتقييم التعبير الجيني لل UGT1A1 والكشف عن المتغاير UGT1A1*28. استخدمت 85 عينة منها في تقييم التعبير الجيني لل UGT1A1, بينما استخدمت ال 40 عينة المتبقية للكشف عن المتغاير UGT1A1*28. اجريت الدراسة الحالية في | A cohort of 125 neonates enrolled in the present study 85 of which subjected to the UGT1A1 expression analysis and forty (40) independent subjects examined for UGT1A1*28 variant. The project was performed in the laboratory of molecular genetics in the collage of education for women, TSB, UCB, BG and ELISA were performed in ATHOP, Assader teaching hospital and Annajaf private laboratory in the period from may to October 2013. Analysis of the UGT1A1 gene expression showed considerable decrease in UGT1A1 expression with relative risk 1.46. Analysis of regression of UGT1A1 mean against severity showed significant inverse correlation between severity of NH and mean UGT1A1 level (r = - 0.99, p = 0.03). Results showed that UGT1A1 expression in males significantly lower than females. Analysis of UGT1A1*28 showed that 80% of the hyperbilirubinemic neonates were positive while 20% were UGT1A1*28 negative. Concluding that there are a considerable proportion of neonates in our community not expressing UGT1A1 enzyme; therefore, they are a risk group for kernicterus. And must be registered and followed up because they are at risk of carcinogenicity, therefore, irinotecan (an anti cancer drug) and similar compounds toxicity. Expression of UGT1A1gene is higher in female than in male neonates, while neonatal jaundice is less severe in female than in male neonates. Eighty percent of jaundiced neonates are UGT1A1*28 mutants. Defective UGT1A1 is the main underlying cause of NJ in our community.

Abstract: طفيلي المقوس الكونديToxoplasma gondii هو طفيلي ابتدائي اجباري داخل الخلايا ذات النواة. له القابلية على اصابة جميع حيوانات الدم الحار ويعد هذا طفيلي ذو اهمية صحية نظرا لما له من تاثيرات مرضية. لقد اجريت عدة دراسات بينت التغيرات النسيجية التي اثرت على انسجة | Toxoplasma gondii is an a zoonotic, obligate intracellular protozoan parasite that has the capacity to infect all warm - blooded animals. Many studies done to present the histological changes of the placental and fetal tissue and organs that resulted by Toxoplasmosis infection of pregnant women and about identification of infected fetal organs, but a lot of these studies were done experimentally on laboratory animals, accordingly the present study aims to study the structural changes of the placenta and fetal tissue and to identify the fetal organs in which the organism localized that taken from aborted fetus and embryos from pregnant woman that diagnosed as infected with Toxoplasma gondii. The present study was carried out during the period December 2012 to March 2013. Eighty women who had abortion chosen randomly from that which were revised gynecology theater in hospitals in Baquba city. Their age were ranged between 16 - 45 years, (10) fetuses and (33) samples of them non - infected as control group (c) and (37) samples were infected with Toxoplasmosis (I). The study included serological examination for mothers and Macropathlogical (Gross) , histopatholgical examination and Immunohistochimcal (IHC) stain of the placenta and fetal organs. Toxoplasmosis diagnosed serologically by ELISA (Enzyme Linked immune Sorrbant Assay) test. Immuno - histological techniques are used to detect the antigen and determination of their morphological localization in fetal and placental tissue. Formalin fixed paraffin embedded tissues (placenta and specimens of organs from aborted fetus) used to determined the antigen (Toxoplasma gondii) to detect the histological changes in these tissues. The ordinary histopathlogical changes of the tissue taken from aborted fetus showed different infiltration inflammatory cell and necrosis changes in brain, liver, lung, upper and lower limbs, kidney and spleen that may be due to infection of the parasite and not all infected organs localized the parasite (Tachyzoites). The results of the study showed that (46.26%) of the randomly selected mothers among that revised to the delivery theaters and had abortion. The fetal tissue and organs of the age (8 - 24) weeks gave positive (+) result for IHC in fetuses(brain and lung) and tachyzoites was detected in that organs, but fetus tissue of the age (4 - 8) weeks was negative for that test. Macropathlogical study of the placenta showed that the weight of the infected placenta was less than the normal ranges. and calcification was not significant in the infected placenta(45.7%) compared with non infected samples (4.28%). Infarction observed high significant in infected group was 25 (35.71%) compared with control group (2.85%) (p=0.001).Necrotic foci also seen as (40%) in infected group compared with control group (14.28%), differences between the two groups was statistically significant (p=0.001). Also congestion observed high significant (p=0.001) and the congestion was seen in (45.71) in infected group and (5.71%) in control group. Histopathlogical examination for placenta showed hemorrhage, necrosis, fibroniod necrosis and degeneration in trophoblastic cell, in both first and second trimester of pregnancy. Villous vascularity observed decreased as (32.85%) in infected group compared with control group (2.85%). Fibronoid necrosis in villi showed high percentage in villi which have > 3 that observed in infected group as (72.9%) compared with control (12.12%). An increased in villous stromal fibrosis was seen in (70.27%) placenta in infected group compared with control group which was (24.24%)

Abstract: : توجد هناك عدة عوامل تلعب دور مهم في زيادة الاصابة بطفيلي المشعرات المهبلية وهذه العوامل تتضمن : اختلال مســـــتوى الهرمونات الجنســـــية, تغير الرقم الهيدروجيني للمهبل, بعض انواع الاصابات البكتيرية.الهدف من الدراسة : اولا : تحديد نسب وانواع الاصابات ال | Introduction : It have been founded that many factors play important roles in the increase incidence of infection with Trichomonas vaginalis these factors includes : disturbances in sex hormones level, change in pH of vagina and some types of bacterial infections.Aims : First : To determine the rates and types of Microbial vaginal infections that infected women in Baquba - Diyala province.Second : study of the relationship between the Trichomonas vaginalis and other microorganisms.Third : study the relationship between the Trichomonas vaginalis and the levels of some sex hormones.Patient and Methods : This study was carried out on 227 patients attended either Al - Batol Teaching Hospital for Maternity and Children in Baquba - Diyala, or some private clinic in Baquba city, most of these patient giving symptoms of vaginitis as a patient group, in addition to 10 healthy women as a control group.Patients group included married, widows and divorcees women with age range between (18 - 45) years, and at different educational level.Full clinical evaluation was done for those patient including history and physical examination. This evaluation revealed that 209 of patients (92%) had vaginal discharge, irritation and itching. Reguested blood samples were taken for laboratory test included estradiol, progesterone and testosterone. The level of these sex hormones in women with Trichomoniasis have been determined and compared with levels of these hormones in control group.In addition high vaginal swab were taken for microbiological tests. and used for diagnosis of Trichomonas vaginalis and other associated microorganisms, the rate of parasitic infection had been determined and it's relation with age group, marital status, level of education and level of vaginal acidity had been estimated. Moreover, the percentage of cases, with pus cells, epithelial cells, red blood cells and clue cells have been estimated. Results : the results of laboratory tests elicited the presence of Trichomonas vaginalis (6.3%). And in addition to it there is bacterial and fungal vaginal infection and the percentages were (54%) and (15%), respectively. Moreover, the results showed the presence of dual infections between the parasite and bacteria, the parasite and fungi, and bacteria and fungi and there percentages were (11.8 %), (8 %) and (4.9 %), respectively.Regarding age group, results showed that the highest parasite infection rate was among women in the age group (26 - 35 years) which was (41.1%), in compare with infection rate in others age group (18 - 25 years) and (36 - 45 years) which were (9.3 %) and (18 %), respectively. Regarding, the marited status, the highest infection rate was founded among married women in comparison with widows, divorcees women, and the percentages were (31.7 %), (6.8 %) and (14.7 %), respectively. Regarding, the educational level, the results showed highest rate of infection with Trichomonas vaginalis was among women with low educational level which was (11.8%) in compared with those with intermediate (7.9%), secondary (4.8%), and tertiary education (1.3%). Regarding, the pH of the vagina, results showed that the rate of vaginal infection were high when pH of vagina > 4.5 in comparison with the lowpH ? 4.5 and the percentages were (83.7%) and (16.3%), respectively. The results of direct smear and cultures showed that (25.9 %) of case (59 patient) were infected with Trichomonas vaginalis, (31.7%) of case infected with E.coli, (27.7%) of case infected with candida albicans, (21.1%) infected with Gardnerella vaginalis, (17.6%) percentages of Lactobacillus spp. (8.3%) percentages of Staphylococcus epidermidas (5.2%) in fected with S. aureus, (3.5%) infected with Enterobacter spp., (2.6%) infected with Proteus spp., (2.2%) infected with Klebsiella spp., (1.7%) infected with Acentobacter spp. and Streptococcus spp., (1.3%) infected with Pseudomonas spp., While the lowest rate was for Neisseria gonorrheae (0.8%). Also results showed that the highest percentage of dual infection with trichomoniasis it was in Gardnerella vaginalis which detected in 22 case (37.2%), followed by Candida albicans, which detected in 18 case (30.5%). While the lowest rate was with Neisseria gonorrheae which detected in one case (1.6%). The other laboratory tests including hormonal estimation in patients with trichomoniasis, the results of current study showed decrease level of estradiol hormone in women infected during follicular and luteal phases of the menstrual cycle, In follicular phase the mean of estradiol was (6.83 pg/ml) in comparison with control group that hormone rate was (42.61 pg/ml). In luteal phase the mean of estradiol was (27.00 pg/ml) comparison with control group which hormone rate was (87.16 pg/ml). In addition to that the level of progesterone have increased in follicular phase but decreased in luteal phase in comparison with control group. In follicular phase the mean of progesterone was (5.89 ng/ml) in com - parison with control group which hormone rate was (0.72 ng/ml). In luteal phase the mean of progesterone in infected women was (0.56 ng/ml) comparison with control group in which hormone rate was (19.83 ng/ml).Regarding, the level of testosterone, the results showed that the level had been increased during the follicular and luteal phases in infected women compared with control group. In follicular phase the mean of testosterone was (3.44 ng/ml) in comparison with control group which the mean was (0.24 ng/ml). In luteal phase the mean of testosterone was (3.65 ng/ml) in comparison with control group in which the mean was (0.30 ng/ml).Conclusion : The presence of infection with Trichomonas vaginalis, and it's associated with other microorganisms that are detected in the current study and other study previous may indicated a correlation between them. So those patient, constantly in need for a panel of laboratory test including : vaginal pH, and hormonal estimation as these factors may play a role in diagnosis and follow - up of the patients.

The samples were collected after 3 - 5 day abstinence period at fertility center Laboratories / ALsader Medical city in An Najaf province.For the period from 1/10/2012 to 30/4/2013.Because the studies about varicocele are rare, the present studies aimed to know the impact of varicocele on semen and sperm parameter, sperm quality index, Malondialdehyde concentration and the percentage of sperm DNA integrity.So, this study was aimed at investigation wethere the Varicocelectomy in varicocele patients could positively influence studied parameters.The research was involved examining 83 sample of seminal fluid for varicocele patient. The percentage of varicocele grades were examined and the results were represented 40% grade1, 39% grade2 and 21% grade3.The result were showed a significant decrease (P<0.05) in sperm concentration , progressively motile sperm, normal sperm morphology percent and sperm viability percent for varicocele patient compared with the fertile persons, while there was noticed a significant increase (P<0.05) in Round cells concentration snd liquefaction time for varicocele patient compared to fertile person and the result of this study were showed significant decrease (P<0.05) of sperm quality index and sperm DNA integrity for varicocele patient compared to fertile persons (control).The study noted to the significant increase (P<0.05) of malondialdehyde concentration for varicocele patients compared to fertile persons. The coefficient factor was used to investigate the correlation between malondialdehyde concentration and the studies parameter.there was increase correlation (P<0.05) between malondialdehyde concentration and sperm concentration(r= - 0.86 P<0.05) progressively motile sperm (r= - 0.938), normal sperm morphology percent (r= - 0.90 P<0.05), sperm viability percent (r = - 0.846 P<0.05) and sperm quality index (r = - 0.836 P<0.05), while there was (P<0.05) positive correlation between malondialdehyde concentration and semen volume (r=+0.822 P<0.05), liquefaction time (r = +0.828 P<0.05) and round cells correlation (r= + 0.89 P<0.05).Also the coefficient was used to study the correlation between sperm DNA integrity and other study parameter. The results of this study were showed positive correlation between the percentage of DNA integrity and sperm concentration (r= +0.88 P<0.05), progressively motile sperm (r=+0.78P<0.05), normal sperm morphology (r= +0.86 P<0.05), sperm viability percentage (r=+0.87 P<0.05) and sperm quality index (r= +0.81 P<0.05), while it was noticed in used correlation between sperm DNA integrity and malondialdehyde concentration (r= - 0.681 P<0.05), semen volume (r= - 0.67 P<0.05), liquefaction time (r= - 0.65 P<0.05) and round cells (r= - 0.54 P<0.05). The effect of varicocele grading on sperm and semen parameter, sperm quality index, malondialdehyde concentration and percentage of sperm DNA integrity was studied, the result were showed a significant decrease (P<0.05)of sperm concentration, progressively motile sperm, sperm viability and normal sperm morphology percentage, and a significant increase (P<0.05) of liquefaction time and Round cells concentration for varicocele patients grad1, grade2 and grade3 compared with the fertile persons. and when we are compare between varicocele patient according to type of grade the results were show a significant decrease (P<0.05) of sperm concentration, progressively motile sperm and normal sperm morphology percentage and a significant increase (P<0.05) of liquefaction time for varicocele patients grade2 and grade3 compared to grade1 varicocele patient.So the result showed a significant decrease (P<0.05) of sperm concentration for grade3 varicocele patients compared with the grade2 varicocele patients. The result of this study were showed a significant decrease (P<0.05) in sperm quality index and sperm DNA integrity for grad1, grade2 and grade3 varicocele patients compared to fertile persons. also it was noticed a significant decrease (P<0.05) of sperm quality index and sperm DNA integrity for grade2 and grade3 varicocele patients compared to grade1 varicocele patients but the malondialdehyde concentration according to varicocele grade, the result were showed a significant increase (P<0.05) of malondialdehyde concentration for grade2 and grade3 varicocele patients compared to grade1 varicocele patients and fertile persons. In this study the effect of Varicocelectomy on study parameters was studied and the result were showed a significant increase (P<0.05) of sperm concentration, progressively motile sperm, sperm viability percentage, normal sperm morphology, percent, sperm quality index and sperm DNA integrity and a significant decrease (P<0.05) of liquefaction time and malondialdehyde concentration for Varicocelectomy compared to varicocele patients. The result were showed a significant decrease (P<0.05)of sperm viability percent, normal sperm morphology percent, sperm DNA integrity and sperm quality index and a significant increase (P<0.05) in round cells concentration, liquefaction time and malondialdehyde concentration for Varicocelectomy patients compared to fertile persons.From the result of present study, we are concluded that varicocele has been negatively impact on sperm and semen parameters, malondialdehyde concentration and sperm DNA integrity, and the effect of varicocele is associated with the increasing of varicocele grading, while Varicocelectomy has been positive impact on sperm and semen parameters, malondialdehyde concentration and sperm DNA integrity but this result have not reached to similar state to fertile persons

A total number of Pseudomonas aeruginosa isolates accounted for 89 of 160 samples.The distribution of these isolates were 28 from Burns, 14 wounds, 15 urine, and 32 from hospital environments. Identification of isolates has been accomplished depending on phenotypic diagnostic methods and PCR technique.our study proved that PCR technique depending on oprI and oprL genes was a rapid method for identification of non - pigmented isolates. A total of 20 antibiotics resistant isolates were chosen for Molecular studies. The result reveling that 100% of isolates had a chromosomal mutation in the QRDRs of genes (gyrA, gyrB, parC, and parE). High percentage of isolates(45%) carried mutated genes gyrA and parC, followed by 15% of isolates were carried either mutated gene gyrA alone or three mutated genes gyrA, parC, and parE and and 10%of isolates were carried three muted genes gyrA, gyrB, and parC, while gene that encoding to parC mutation were detected in 5% of isolates. Our study is the first study about detection of Quinolone Resistance Determining Regions in P.aeruginosa in Iraq. The results showed the the presence of mexAB - oprM multidrugs efflux system expression in 100%(20) isolates. while the phenotypic test depending on MIC values for ciprofloxacin alone in the presence of efflux inhibitor showed that only 15%(3) isolates had the active efflux pump.

The age average was (1.36±30.9) , (0.98 ±29.6) and (1.63± 31.4) years respectively. The samples were restricted to the non smoking patients only. The study results show a significant (P< 0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the sperm viability percent and the semen volume, and a significant (P<0.05) increase in the round cell concentration, liquefaction time, Malondialdehyde concentration and the percent of the abnormal chromatin of the Normozoospermic and the Asthenozoospermic patients comparing with the fertile men. The results also show a negative correlation (P<0.05) between the (MDA) concentration and the parameters represented by the sperm concentration, percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent sperm quality index and semen volume. While it had been noticed that there was a positive relation between the MDA concentration and the parameters represented by the sperm liquefaction time, round cell concentration and the abnormal sperm chromatin percent of all the study groups. In this research the relation between the sperm chromatin damage and the other study parameters had been studied by dividing the samples according to the degree of chromatin damage. The results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent, the sperm quality index and semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration (MDA) concentration and the percent of the abnormal chromatin of the group (> 10) comparing with the group (? 10) for the fertile men, also the results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent and the semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration for the group (> 25) comparing with the group (? 25) for the infertile Normozoospermic patients. For the Asthenozoospermic patients the study shows a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm quality index, the sperm viability percent and semen volume, and a significant (P<0.05) increase in the liquefaction time and round cell concentration for the study groups represented by the group (> 20 - 40) and (< 40) comparing with (? 20). From the above results it could be concluded that the increase of (MDA) level resulted from the active (ROS) leads to an increase in the abnormal chromatin percent of the infertile Normozoospermic patients which had a negative effect on the semen parameters which could be a reason for the infertility for those patients

Abstract: يعد السرطان واحدا من المخاطر الاساسية التي تهدد حياة الانسان في مختلف بلدان العالم، لان هذا المرض لا يقف عند عضو معين فهو ينتشر الى كثير من اعضاء الجسم الاخرى ليفتك بها، ومن هذا انطلقت الدراسة الحالية التي اجـريت للفترة من تشرين الاول / 2012 م ولغاية اب | The Cancer is one of highly risk factors that threats the human life world wide, because the disease has metastatic property from primary to secondary sites. This study was carried out during the period extending between October 2012 and August 2013, in laboratories of Faculty of Veterinary Medicine & Faculty of Education for girls in University of Kufa. It is aimed to follow up the changes in volume of growing tumor in female albino mice which were injected with cells of murine mammary adenocarcinoma.The histological changes, immunohistochemical examination investigate the distribution of CD8+ T lymphocytes were also studied.The changes of IgG and IgM titers in serum were also investigated. The study included use of 40 female albino mice at age 6 - 8 weeks, 25g weight average.All mice were injected by cells of murine mammary adenocarcinoman (AM3) in subcutaneous of femoro - dorsal region, and ascending to cervical region. The tumor was successfully implanted into 28 mice.These mice divided into four groups, each contains seven tumor - bearing mice.The animals of the first group subjected to the investigations after 48 hrs from implantation , while those of 2nd, 3rd & 4th groups after 10, 20, 30 days respectively. Seven healthy mice were considered as control group to comparison of immunological tests. Tumor volume & relative tumor volume were measured in different experimental groups. Histological section were prepared by routine histological techniques that including the steps of dehydration, clearing, infiltration, embedding, cutting & staining by hematoxylin and eosin stains, then microscopical examination had been done by optic microscop. The results indicated there was significant increase in tumor volume and relative volume with advancing of tumor age in animals of 2nd, 3rd & 4th groups where compared with first group. The gross examination of the animals of different groups showed that the tumor grew as irregular projection with loss of hair and erosion of overlying skin with milky discharge. The post - mortem examination revealed that the tumor mass was divided into small lobules with various coloures and the tumor mass surrounded by fibrous tissue which increase in thickness as the tumor increased in the age. Extensive areas of necrosis were noticed in the centers of the tumor masses. The microscopic examination of tumor masses in the first group raveled there were sub cataneous small aggregation of tumor cells at the implantation region as well as dispersion of the implantated tumor cells. The inflammatory cells, especially neutrophils were infiltrated. In the second group, the tumor masses showed lobulation by fibrous septa with proliferation of new blood vessels with congestion of them. Infiltaration of inflammatory cells, particularly the lymphocytes. The tumor cells arranged as ribbons and acini, characterized by hyperchromacia pleomorphism, high N/C ratio as well as appearance of mitotic figures. The histological features of the third group revealed increase of amount of fibrous tissue extensive necrotic areas and loss of architecture.These appeared in the fourth group in addition to the presence of cellular debris with dead inflammatory cells. The immunohistochemical study showed no CD8+ T cells were infiltrated in the mass of first group but the little infiltration of these cells was show in the second group. The highest infiltration of the CD8+ T cells was appeared in the third group. while the little cells were discharged in the fourth group. The results of the single radial immunodiffussion assay showed that the implantation with mammary adenocarcinoma had significant effect in increasing the titer of IgM after (48) hours and (30) days from implantation of tumor compared to control group, while the titer is not significant after (10) and (20) days from implantation of the tumor compared to control group. Also the results revealed a significant decrease in the titer of IgG after (48) hours and (30) days from implantation of the tumor, while were no significant increase in the titer of immunoglobulin after (10) and (20) days from implantation of the tumor, compared to the control group. From all the above, We concluded that there was variable histological changes as the age of tumor advanced these changes were characterized by increase of amount of tumor cells in the first groups and occurrence of necrosis in late groups, as well as increase the fibrous tissue as the tumor age advanced. The infiltrative CD+8 lymphocyt was also variable as change of tumor age. The implantation of tumor in mice groups had marked effect in stimulation of humoral immune response through increase of IgM & IgG titers.

A total of 120 specimens were collected from patients of both gender with different ages whom infected with oral thrush, uro - genital and Gastrointestinal candidiasis and admitted the General Teaching Hospital and materinaty and children Teaching Hospital in AL - Diwaniyah city during the period from December/2012 to February / 2013. The isolation and identification of yeast isolates were done based on their morphological, Cultural and biochemical tests in addition to use the confirmatory systems such as the growth on Chrom Agar candida, Api Candida and Tobacco Agar medium to distinguish C.albicans from other yeast spp. Also, some virulence factors of C.albicans such germ tube formation, chlamydospores production, growth at of 45 c and resistance to cycloheximide were detected. The antibiotics sensitivity test was used in two method (disk diffusion & dilution) to determine the sensitive, trailing growth, resistance isolates and minimal inhibitory concentration (MICs) toward azole agents. The qRT - PCR was used to detect the relative quantitative of Erg11 gene expression and its relationship with resistance to azole and emergence of trailing growth phenomena in the presence of Fluconazoles and ketoconazole. The isolation and identification results revealed that the isolation percent of C.albicans was 47.05 % incomparison with other Candida species that were 15.3%, 11.76 %, 8.23 % and 5.9 % for C.krusi, C.dubliniensis, C.tropicalis, C. parapsilasis and C.glabrata , respectively. The antibiotic susceptibity tests of C.albicans showed the presence of resistance precent (38.89%) to fluconazole and the most of sensitive isolates revealed a trailing growth phenomena in the zone of growth inhibition of floconazole in a ratio 55.56%. While the resistance percent to ketoconazole was 27.78 % and the sensitive isolates showed the trailing growth in a ratio (38.89%). The statistical analysis showed a significant differences (P <0.05) among tested treatments. The MICs values of fluconazole against C.albicans isolates were 8, 16, and 64 Mg/ml for sensitive isolates and were 0.125 and 0.5 Mg /ml for resistance isolates and the trailing growth phenomena occurred at MICs value ? 8 Mg/ml within 24 hours of incubation while the values became ? 64 Mg/ml after 48 hours of incubation.There was a significant differences (p< 0.05) among tested treatments isolates incubated at 24 hours while there was no significant differences (P>0.05) at 48 hours of incubation. In respect with Ketoconazole, the resistance of C.albicans was increased after 48 hours of incubation at MICs values 0.125, 0.25, 0.5 and 1 Mg /ml while its was sensitive at values 4, 8 and 16 Mg /ml and the trailing growth phenomena occurred when the MICs ? 2 Mg/ml after 24 hrs of incubation, while it reached to ? 8 Mg/ml after 48 hrs of incubation. There was a significant differences (p< 0.05) among tested treatments incubated after 24 hours while there was no significant differences (P >0.05) among treatments after incubation 48 hours. The results of relative quantitative gene expression for both genes revealed a significant differences (p< 0.05) in gene expression levels through the occurrence of increased in the transcription of mRNA quantity among tested treatments.The up - regulation of Erg11 and fold change in mRNA transcription was 2.498 fold compared with 1.0 for control treatment after 24 hrs of incubation in the presence of antifungal, while the increasment was 12.606 fold after 48 hrs of incubation of isolates with antifungals.

Four stations were selected for sample collections over the distance of 25 km. Two stations were in Tigris river and two were in the treatment unit. The first selected station was close to the old water purification unit in Tikrit - city. The second station was selected at the treatment unit in AL - Dubaee before the mechanical treatment unit. The third station was selected at the treatment unit after the biological treatment. The fourth station was selected in Tigris river about ten km south of the treatment unit at AL - Dijla town. The study involved an investigation of some physical, chemical and biological aspects of Tigris river and the residence waste discharges to the river. This included air and water temperature, conductivity, PH, dissolved oxygen, BOD, Turbidity, total hardness, calcium and magnesium hardness, chloride, total alkalinity, nutrients (i.e., phosphate, nitrite, silica) , and the concentrations of heavy metals (i.e., cadmium and cupper). The biological factor included the total bacteria counts cultured on nutrient agar. Results of the study clarify the close relation between air and water temperature which varied (8.5 - 36) C0 and (9 - 27) C0 respectively. Conductivity values were relatively high and ranged (128 - 3530) microsemens/cm. River water almost was alkaline during the period of the study. PH values of the first and fourth stations were close in the river, although a value of 6.12 was recovered at station on during May. In all stations, PH values ranged (8.8 - 6.12). River water has a good ventilation, dissolved oxygen values ranges (8 - 11) mg/L at the first and the fourth stations, while these values were (0.1 - 1.34) mg/L at the second and third stations. Mean dissolved oxygen values pointed out the availability of good oxygen concentration for the continuity of living organisms which ranged (0.3 - 5.8) mg/L in Tigris river, while BOD values at the stations second and third were high and ranged (5.6 - 131.2) mg/L. Turbidity was high during April at the stations one and four and ranged (2.03 - 788) NTU in all stations. Total hardness in Tigris river was slightly low - very hardness and ranged (120 - 360) mg/L at the first and fourth stations, while these values were (180 - 480) mg/L at stations two and three.The high total hardness values coincided with the high conductivity values. Concentrations of calcium ions responsible on the calcium hardness ranged (211.4 - 120.7) mg/ L was higher than magnesium ions responsible for magnesium hardness range (5 - 265) mg/L.Records of chloride ions ranged (14.16 - 169.99) mg/L at all stations. However, chloride values at stations first and fourth were among the allowed world values and ranged (14.16 - 42.48) mg/L.Alkalinity values were due to the carbonate and bicarbonate and ranged (35 - 725) mg/L.phosphate values ranged (0.168 - 25.2) µg phosphor atom - phosphate/L. Low nutrient values recorded in Tigris river, while the highest values recorded at second station (treatment unit).Nitrite values fluctuated at all stations and ranged (0.078 - 14.778) µg Nitrogen atom - Nitrite /L. Silica values ranged (648 - 5961.6) µg silicon atom - silica /L. Heavy metals values (Cadmium and Cupper) clarify that, Cadmium were (un sensible), except one value (0.008) mg/L that recorded at November, and un sensible for Cupper.Results of the statistical analyses of all involved factors showed significant differences at stations first and second, and between the first and third stations as well as the fourth station. While there was no significant differences between the second and fourth stations. And no significant differences between stations first and fourth.Total bacterial counts indicated high bacterial counts, and the average of total bacterial count ranged (2.605X105, 5.44X108, 2.265X108, 2.385X105) / ml at the four stations respectively, so the Tigris river considered pollutant - very pollutant.

Abstract: The morphological and histological structure of digestive tract in one species of Iraqi fish that resides in Iraqi inland fresh water (Liza abu) was studied. In this study used (43) fish were in different lengths, the gut of these fish have removed to study the relationship between the length of gastrointestinal tract and the standard body length as well as for morphological and histological study. The value of relative digestive tract length (RGL) was 2.9. Intestine was the longest part of the digestive tract, the average length of intestine was (32 cm). The shape of the folds of the mucous membrane lining the walls of digestive tract showed some differences in different parts of digestive tract, in esophagus the folds were longitudinal running along the wall and it was straight, unbranched and the mean of their number was (9 - 8) folds. In the stomach the folds were longitudinal and (7 - 6) in their number, they were branched into fingerlings structures. In pyloric caeca, anterior and posterior part of intestine and rectum the folds were fingerlings in shape, unbranched and their number were (20 - 19), (27 - 26), (25 - 23), (19 - 18) respectively. Histological study was shown that the wall of the digestive tract is consist of four major coats, from the inside to the outside they were as follows : Tunica Mucosa which characterized by its clear three parts, epithelial tissue, lamina propria and muscularis mucosa. Epithelial tissue in esophagus was thick stratified squamous epithelium, in stomach was thin simple columnar epithelium and gradually increase in length in each of pyloric caeca, intestine and rectum and it was simple columnar epithelial tissue. Mucous which is secreted in esophagus is made of a large proportion of neutral and acidic mucopolysaccharide, while the mucous secreted in the cardiac stomach consist of a large proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, either, in the pyloric stomach is consist of very small proportion of both neutral and acidic mucopolysaccharide, in pyloric caeca mucous consist of a small proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, and the mucous secreted in an anterior, posterior parts of intestine and rectum consist of small proportion of acidic mucopolysaccharide and large proportion of neutral mucopolysaccharide. Lamina propria consists of connective tissue containing capillaries and lymphoid cells and it represent the basis of the folds, in the cardiac stomach it contains simple tubular glands. Muscularis mucosa characterized by the presence of muscle fibers that are not continuous, the higher thickness of this layer was in pyloric stomach. Tunica Submucosa consists of connective tissue that contains capillaries, the higher thickness of this coat was in the stomach and less thickness of this coat was in the rectum. Tunica Muscularis consists of two layers of smooth muscle fibers, the internal layer has a circular arrangement, the external layer has a longitudinal arrangement in stomach, pyloric caeca, intestine and rectum. either in esophagus tunica muscularis was arranged in inverse manner. The circular and longitudinal muscle fibers in esophagus were skeletal muscle fibers, and they were smooth and non - striated in stomach, pyloric caeca, intestine and rectum. the higher thickness of this coat was in the stomach and less thickness was in the rectum Tunica Serosa is present in all regions of digestive tract.

Abstract: Cryptic bacterial infection has been studied in urinary system to Human, where 50 underwent urine samples from patient mostly based consulting auditors Hilla public Education Hospital for the period from November 2012 until Feb. 2013. Patients ranged in age from 20 - 50 years males and females bacterial infection rate was 70% distributed between the cell wall defective bacteria had 38% and 32% cell - wall bacteria and the results showed 30% as negative cases. Amicroscopic examination of the urine sludge Showed clear sovereignty of non - specialized immune response type of mixed cell 34% followed by mononuclear cell 30%. Samples were cultured on routine media (Blood agar , Macchonky agar) and Modified media (Variant agar, Variant broth). Out put diagnosed by bacterial system diagnostics, phen - otypic, microscopically and biochemistry by using the special test for microorganism diagnosis and using API 20 E and the use VITEK 2 to confirm some samples results. Characterized by colonies of cell wall defective bacteria grow on variant agar it resembles fried egg which could seen after staining Deinse stain. Citrobacter freundii recorded 12%, the highest rate among cellwall defective isolates. Sensitivity test for bacterial isolates were screened from U.T.I both two type (CWB & CWDB) showed the highest rate of sensitive to Impinem 100% represented CWDB, as well as the highest rate of resistance to Ampicillin 100% represented by the same group of isolates. experimental study with urinary tract infection by injecting bacterial stuck of Citrobacter freundii to the three groups of rabbits : first group ( 3 Rabbits ) : immunized with viable surface antigen extracted from CWDB, second group : ( 3 Rabbits ) immunized with heat killed surface antigen extracted from CWB, the third group (4 Rabbits) represented control group it been treated with sterile normal saline. the injection process through urethra, and then underwent a histological study, was histological damage to the members of the animal - derived non - immunized (control group) seemed clear was the appearance of symptoms of the total cellular infiltration and disruption of the mucous layer and epithelial and other symptoms. The immunized animals have shown their ability to defy injury. It is the study of serological reactions to bacterial antigens Citrobacter freundii immunized with vaccines for rabbits given high caliber agglutination with its specialized vaccines and low with adversity and that the absorption and the corresponding and variant antigen does not remove the agglutination effectiveness with immune sera prepared suggesting that the absorption is incomplete and that the difference between the wall and a wall defective in terms of antigenic is quantitative and qualitative.

Abstract: The present study was sought to investigate the inhibitory effect of four crude aqueous plant extracts : Zingiber officinale Roscoe (ginger), Camellia sinensis (Green tea), Olea europaea (Olive) and Hibiscus sabdariffa (Rosella) on key enzyme linked to hypertension, Angiontensin - I Converting enzyme (ACE), and on the oxidant/antioxidants status, lipid profile in vitro and in vivo studies. Study of some biochemical biomarker demonstrated that antioxidant enzyme, oxidant enzyme, liped profile and ACE level for 75 hypertension patients. Antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx) were shown to have cross relationship with ACE level in hypertension groups, while lipid profile have positive relationship with ACE level in hypertension groups. ACE activity for the four groups G1, G2, G3, G4 were 19.61±3.97, 21.3 ± 1.95, 28.06 ± 5.34 and 32.74±8.19 ng/ml respectively. From these results we concluded that ACE was associated with hypertension and its modulated by drug or herbal extracts. Angiotensin - I Converting enzyme was extracted from sheep lung with specific activity 0.08 U/mg, then the crude ACE extract was concentrated with sucrose by dialysis with specific activity 0.1 U/mg, purification fold was 1.25.The enzyme was purified partly by ion - exchange chromatography using DEAE - cellulose with specific activity 0.5U/mg, yield 30% and purification fold 6.25. ACE activity was determined using N - [3 - (2 - furyl) acryloyl]L - phenylalanyl glycyl glycine (FA - PGG) as a substrate. Results for in vitro ACE inhibitory activity using plant extracts (ginger, green tea, roselle and olive) showed that the all four crude aqueous plant extracts had inhibitory activity in different values when used in the same concentrations about (1 mg/ml), and ginger extract possessed higher inhibitory activity than other three extracts. The ACE inhibitory potency of the ginger extract was found to be significant (P<0.001) when compared with the standard anti - ACE inhibitor drug (Captopril) at the same concentration. The inhibitory activity of ginger extract with different concentration (25, 50, 100 mg/kg) in L - N - ? - nitro - L - arginine methyl ester (L - NAME) induced hypertensive mice was evaluated. Acute oral administration with L - NAME 50mg/kg.b.w causes a rise in blood pressure in normal mice. Administration of aqueous ginger extract (25, 50 and 100 mg/kg) for 4 weeks in L - NAME treated mice significantly (P<0.05) reduced the mean arterial blood pressure compared with L - NAME animals without treatment, with decreasing the serum levels of ACE; while the activity of superoxide dismutase (SOD) and glutathione peroxidase(GPx) showed a significant elevation in ginger treated L - NAME induced hypertensive mice. The results suggest that ginger extract could prevent the development of high blood pressure induced by L - NAME probably can be attributed to prevent or reduce the oxidation process and the inhibition of physiological processes of a substance L - NAME and so as it contains ginger compounds of polyphenols, which inhibits the activity of the ACE and prevent oxidation of fats and repair System Antioxident. Our study concluded that ginger might act as a natural alternative to better and safer in the prevention of negative impacts and risk factors such as high blood pressure and lipids.

Abstract: SDS - PAGE showed that a single sharp band with an approximately 16.8 KDa molecular weight has been seen. A matter indicates that the enzyme is consistently pure. PCR technique was applied to approve the existence of nuc gene in S.aureus Nevertheless, only those which depicted positive results on DNase agar harboured nuc gene, as it is specified by single band appearance of nuc at assumed molecular weight (ca. 255 pb) of marker that being used. The current study findings highlighted the participation of SNase purified from S. aureus in significant (P< 0.05) preventing biofilm formation by E. coli and K. pneumoniae compared with untreated controls. Evidently, the inhibitory effect of SNase on biofilm formation is undoubtedly perceived, indicating the degradation of the structural major component of biofilm formation (i.e. extracellular DNA). Results revealed that SNase was able to significantly (P< 0.05) reduce the number of the uropathogens; E. coli and K. pneumoniae attached to the uroepithelial cells. 1 Chapter one : Introduction and literature Review 1. Introduction and Literature Review 1.1. Introduction Staphylococcus aureus is a persistent human pathogen that is responsible for a range of diseases that vary widely in clinical presentation and severity. The pathogenesis of S. aureus infection is a complex process involving a diverse array of secreted and surface - associated virulence determinants that are coordinately expressed at different stages of infection (Loughman et al., 2009). Escherichia coli is a genetically diverse species that causes a variety of infections which fulfill many or all of the proposed criteria for biofilmassociated infections (Kaper et al., 2004). Klebsiella pneumoniae is an opportunistic pathogen responsible for a wide range of nosocomial infections. One important factor associated with virulence in K. pneumoniae is its capacity to adhere to surfaces and form biofilms (Cruz et al., 2012). Bacteria often exist as sessile communities called biofilms which are exquisite structures caused by a genetically programmed developmental process. It is estimated that biofilms are involved in 65% of human bacterial infections, since cells in biofilms are 1000 times more resistant than cells in the planktonic state, making medical treatments fail (Shal? et al., 2011). Extracellular DNA (eDNA) plays a significant role in biofilm formation, as revealed by studies in several bacteria including E. coli (Nakao, 2012) and K. pneumoniae (Whitchurch et al., 2002); however, there is no definite proof on a cause - and - effect relationship between DNA release and biofilm formation (Beenken et al., 2012) or becomes a key component of the macromolecular scaffold in many different biofilms (Jakubovics et al., 2013). In rare cases eDNA has been shown to inhibit bacterial settlement. Therefore, it is possible that nuclease mediated eDNA degradation would therefore promote adhesion. Consequently, it is not clear whether microbial nucleases contribute to the gross biofilm structure in clinically relevant situations (Sheilds et al., 2013). 2 Chapter one : Introduction and literature Review All previous studies used both commercial bovine and recombinant human DNaseI in the disruption of medically important biofilms; whilst, extracellular nuclease of S. aureus (SNase) was used against biofilm of S. aureus themselves (Benenken et al., 2012b ; Kiedrowski et al., 2014). Thus, to date, the role of S. aureus exonucleases in biofilm of other bacteria remains unclear. However, in the present study SNase is used against biofilm of other bacterial species (viz. K. pneumoniae and E. coli). To address this, the following steps were undertaken : 1 - Investigating the negative impact of SNase extracted from S. aureus on K. pneumoniae and E.coli biofilm formation. 2 - Studying the preventive activity of SNase on the adherence of K. pneumoniae and E. coli on uroepithelial cell.

Abstract: العكبر (صمغ النحل) Propolis هو نتاج نحل العسل الذي اكتسب شعبية في الطب البديل وذلك بسبب خصائصه الحيوية، وقد استخدم بشكل واسع في الاطعمة الصحية. ان الدراسات المتعلقة بتاثير العكبر العراقي قليلة. ولهذا السبب, فان الهدف من هذا البحث هو تحليل تاثير العكبر الع | Propolis is a honeybee product that has gained popularity in alternative medicine, due to its biological properties and it has been intensively used in health foods. Studies concerning the effect of Iraqi propolis are rare. Therefore, the goal of this work is to analyse the effect of Iraqi propolis on some hematological and biochemical parameters in alloxan - induced diabetic rabbits, as well as study the histological observations of the pancreas, liver and kidney. Female local rabbits (Oryctolagus cuniculus) were used for this study. The overall number of animals used was 30.They were randomly divided into five groups. Diabetes was induced in all rabbits, except normal control, by a single dose of alloxan (150 mg/kg, i.v.). Development of induced diabetes mellitus was confirmed on first week after alloxan administration by examining the fasting glucose level in the blood taken from marginal ear vein. Rabbits with glycaemia were treated with alcoholic extract of propolis for 23 days. Diabetic control group did not treat with propolis. The treated animals were subdivided into three groups according to the dose of propolis extract. Three oral concentrations of propolis extract were investigated (50, 100 and 200 mg/kg/day).The following parameters have been studied were changes in weights of body, liver and kidneys ; changes in the hematological values that include erythrocytes, hemoglobin, leukocytes and hematocrit also changes in the biochemical values which included glucose, total protein, triglycerides, total cholesterol, aspartate transaminase (AST), alanine transaminase (ALT), blood urea, creatinine and Malondialdehyde (MDA), in addition histopathological study of pancreas, liver, and kidneys. The results indicate a significant decrease (P < 0.05) in the body weight of alloxan - induced diabetic rabbits in comparison with control group, while there were significant increases in the weights of liver and kidneys. The present study showed that alloxan induced significant decreases (P<0.05) in all primary blood indices; erythrocytes, hemoglobin, packed cell volume (hematocrit) and leukocytes. Also, serum biochemical changes showed significant increases (P<0.05) in glucose, total protein, triglycerides, total cholesterol, AST, ALT, blood urea, creatinine, and MDA comparison with control group.Histopathological changes in pancreas, liver and kidneys, observed microscopically, revealed degrees of damage in the tissues, while these organs of control groups exhibited a normal architecture. The treatment with alloxan resulted in several forms of histological alterations such as cytoplasmic vacuolation, degeneration, necrosis, cell hypertrophy, nuclear diploid, diffusion of inflammatory cells, dilatation in ducts, stagnation in secretory fluid. in addition, hemorrhage, dilatation and congestion in blood vessels and disorganization of histologic architecture, Generally, the gradual improvement in blood values was noticed with the increase in concentration alcoholic extract of propolis and return back the normal histological shape of pancreas, liver and kidneys. Propolis extract in rabbits had a potent antihyperglycemic effect, antioxidant activities, radical - scavenging capacities, tissue regeneration properties, and that may be due to the high biological activity and nutritive values contents in bee propolis. In conclusion, the results suggest that propolis could potentially contribute for the prevention and treatment of diabetes mellitus.

Abstract: يعد العقم واحدة من المشاكل الاجتماعية المهمة في معظم انحاء العالم.استنادا الى الاحصائيات الحالية حوالي 15% من المتزوجين يواجهون العقم. يؤدي تقييم السائل المنوي غير الطبيعي للاستروجينات الى تشخيص قلة اعداد النطف ونشاطها وشكلها الطبيعي ومن ناحية اخرى تؤثر | Infertility is one of the most critical social problems in the all of population world. According to the current statistics, about 15% of married couples face with infertility. Assessment of abnormal semen parameters leads to diagnosis of oligoasthenoteratozoospermia, and in others, it leads to isolated abnormalities of sperm concentration, motility, and morphology, due to the lack of differentiable or correctable etiology, Both clomiphene citrate and tamoxiphene citrate, as an anti - estrogen, is the most common prescribed medication for male infertility. In humans, ant estrogens interfere with the normal negative feedback of sex steroids at the hypothalamus and pituitary, thereby increasing endogenous gonadotropin releasing hormone (GnRH) secretion from the hypothalamus and follicle stimulating hormone (FSH) and luteinizing hormone (LH) secretion directly from the pituitary. Objective : The objective of this study was to investigate the effect of clomiphene citrate (CC) and tamoxiphene citrate (TC) administered to male mice on quality of sperm parameters.Materials and Methods : Ninety six male mice were divided into two major groups, and every one of these groups was subdivided into three minor groups involving control and two treated groups. In the CC study, 48 mice were administrated orally 0, 0.0125 mg and 0.025 mg as control (G 1), low dose (G 2) and high dose (G 3) for 42 days. While, in the TC study, 48 mice were administrated orally 0, 0.01 mg and 0.02 mg as control (G 1), low dose (G 2) and high dose (G 3) for 42 days. Then, the male mice were sacrificed, both vas deferens were collected and assessment sperm parameters involving sperm concentration, sperm motility and activity, and normal sperm morphology. Results : The results of present study appeared that the use high dose of CC or TC significantly increment (P<0.05) sperm concentration as compared to control groups. However, use high dose of CC significantly increment (P<0.05) percentages of sperm motility and normal sperm morphology. Meanwhile, the percentage of progressive sperm motility was increased significantly (P< 0.05) when low CC dose administered as compared to control and high CC dose groups. In this study, percentages of sperm motility, progressive sperm motility and normal sperm morphology showed best elevation when used low TC dose as compared to both control and high TC dose groups. High TC dose causes significant increment (P<0.05) in the percentage of sperm agglutination when compared to control and low TC dose groups.Conclusions : Based on the results of this study, it can be concluded that the administration of high dose of either CC or TC increases sperm concentration, while administration of low dose of either CC or TC enhances progressive sperm motility.

Abstract: The study had included isolation and diagnosis of three hundred samples for both sexes their ages were between (1 - 60) years of the inpatients and outpatients in Tikrit Teaching Hospital and General Samarraa Hospital during the period from 1/9 / 2011 to 1/3/2012. The infections were distributed among the burns infections, the wounds, urinary tract infections (UTI) and female genital tract infections (High vagina). This study clarified that (192) sample from the total samples showed bacterial growth in percentage 64%. The results of this study indicated to the proportion 58% with (UTI) by (87) bacterial isolation were produced from (150) isolation. The percentage of burns infections were 81.81% from (55) sample which distributed among the first, second and third class burns. The burns of second and third class gave bacterial growth in a proportion 100% while the first class burns gave 64.28%. Concerning the wounds infections, bacterial growth was 62.9% from (62) sample. The infections proportion of (H.V) was 63.63% from (33) sample. The results of the current study showed that the infections in females were higher that in males with respect to (UTI), while there was not considered difference between the males and females about the burns and wounds infections. Differently, the (H.V) infections were just for the females in the ages between (18 - 45). It was clear according to the results of diagnosis that Escherichia coli had the highest proportion of isolations 25.52% from the total isolates followed by Staphylococcus aureus 18.23% Pseudomonas aeruginosa 15.63%, both Klebsiella pneumoniae and Proteus miribilis 10.42% Staphylococcus epidermidis 4.69% Citrobacter freundii 4.17%, Staphylococcus saprophyticus 3.64% both Serratia marcescens and Enterococcus faecalis 2.6%, Streptococcus pyogenes 1.56% and Staphylococcus intermedius had the least percentage 0.5% by one from (192) isolate. The sensitivity of these isolates was tested by (10) antibiotic which included quinolones, aminoglycosides, beta - lactams and tetracyclines antibiotics. Among these antibiotics imipenem and ciprofloxacin were more effective, while the other antibiotics were different either active or not active at all.The wheat germinating was used in this study with the ages (36 - 48) hour and its activity was tested by using some bacterial kinds. After completing several quantitative and qualitative tests on this germinating, the carbohydrates proportion was between 67 - 70%, the protein proportion by folin method was between 10 - 8%, the lipids proportion was 1.5%.Some mineral elements in germinated wheat were estimated which include Calcium, Iron, Magnesium, Potassium, Copper, Manganese, Zinc, Selenium, and Sodium element, active materials were also estimated in the wheat germinating extracts which had inhibitory effect on the microbiology. It was clear by the tests that the germinating contains a lot of Phenolic compounds, Terpeniods, glycosides and steroids. These materials were extracted by using some extracts included the cold water extracts and hot water extracts, alcoholic extracts (ethanol and methanol) and phenolic extract. All the extracts prepared in concentrations (25, 50, 100, 200) mg/ ml. This study showed that the phenolic extract had high effect on the bacterial kinds in comparison with the methanolic and ethanolic extracts at (200) mg/ ml concentration while the cold water extract had less effect on these bacterial isolates in comparison with the above extracts, finally the hot water extract had no inhibitory effect against any isolated bacterial type with all the concentrations. The inhibitory action of these extracts was compared with some antibiotics as a control sample. These antibiotics represents different groups of antibiotics and which contained Imipenem, Ciprofloxacin, Gentamicin, Ceftazidime in addition to Augmentin.In this study the minimum inhibitory concentration (MIC) of the fenolic, alcoholic and watery extracts was determined and the concentration was different according to the extract type, the bacterial type and the isolation site.

Abstract: تم في هذه الدراسة البحث عن امكانية ايجاد مؤشرات وراثية ترتبط بمؤشرات فسلجية وذلك من خلال الدراسة على مستويين : ا - المستوى الفسلجي : زراعة صنفين من الحنطة الناعمةL Triticum aestivum في حقول كلية الزراعة/ جامعة تكريت لموسم النمو 2010 - 2011، وذلك بزراعة بذو | This study was conducted to investigate a genetic marker linked to physiological marker through a design an outdoor experiment which includes two parts : - 1 - Physiological part : Included planting two cultivars of soft wheat (Triticum aestivum L.) in the fields of the college of Agriculture, university of Tikrit, during growth season (2010 - 2011). The stage of work had been done by cultivated the seeds of two cultivars of wheat (Sham - 6, Abu - Ghraib) in pots, when they reached the stage of (4 - 5) leaves it had been exposed to two dryness periods 7 and 10 days. It spread with growth regulator Indole Acetic Acid (IAA) (150 ppm) to know which type is more resistance for dryness through estimation of proline concentration as a physiological marker and to indicate the effect of IAA to reduce the dryness effect in some features of growth physiological function and yield component according to complete Randomize Design (CRD). Some markers of drought tolerance have been estimated including : proline content, chlorophyll concentration and the degree of membrane stability then plants were left for harvesting period. The results of the outdoor experiment were : 1 - Exposure the plants to dehydration periods during their growth caused reducing of the most studied characters (leaf area, plant height, tillers number, concentration of chlorophyll A and B and the total chlorophyll), while there was an increase in the content of the proline and the injury index of plasma membrane. 2 - Some characteristic did not showed effect by drought periods (dry weight of plant, number of days of flowering, spikes number, spike length, number of grains/ spike and weight of 1000 grains).3 - Sham - 6 cultivar was superior than Abu Ghraib - 3 in three characteristic (number of days of flowering, leaf area, weight of 1000 grains), while Abu Ghraib - 3 cultivar was superior in the grains number /spike than sham - 6 cultivar.4 - The concentration of IAA (150 ppm) had a different effect. It had a positive effect in the decrease drought for some characteristic (proline content, injury index of plasma membrane, leaf area, plant height, dry weight, spike number and grains yield).2 - Genetic part : DNA has been isolated from fresh leaves of two types of wheat, arrange yields of DNA were in the range of (40 - 150) micro gram per 1.5 gram of plant leaves, and the purity ranged between (1.2 - 1.7). The reaction PCR was done by using 11 primer of the Random Amplified Polymorphism DNA (RAPD) in addition to two pair of specific primer to detect the genes which are responsible for coding of two enzymes which involved in anabolism and catabolism of proline. The results obtained are as follows : - 1 - Five primer of RAPD did not appear any binding site (OPA - 18, OPL - 20, OPA - 11, OPQ - 17 and OPH - 14).2 - Six primer of RAPD have appeared main and monomorphic bands (OPO - 16, OPH - 07, OPN - 16, OPM - 20, OPJ - 13 and OPQ - 06), in addition to the absent of the other bands from some treatments. 3 - The two pair of specific primer have given three monomorphic bands with different molecules weight.4 - The primer (OPH - 07) has appeared a unique band with molecular weight (1670) pb for Sham - 6 cultivar during second drought period (10 days without hormone). These results obtained from this study were identical with physiological part in the ability of both types to drought tolerance

Abstract: نفذت الدراسة الحالية في مركز بحوث التقنيات الاحيائية/ جامعة النهرين للمدة 2011 - 2012 لغرض الكشف عن جين الملوحة TaGSK1 ودراسة التعبير الجيني له في صنفين من الحنطة فرات ودجلة والتركيب الوراثي 2H المنتخبة لصفة تحمل الملوحة مقارنة مع الصنف تموز2 الحساس للملو | This study was conducted in biotechnology research center, Al - Nahrain university in 2011 - 2012 to detect the gene responsible for salt tolerant (TaGSKI) and study its expression in two wheat (Tigris and Euphrates) cultivars and the genotype (2H) were selected for salt tolerance through improvement and breeding programs as compared with to the sensitive local wheat cultivar (Tamooze 2). Seeds of the these cultivars were sown in flasks that contained Ms media in three salt levels (0, 15, 25) ds/m with three replication for each. Five seeds from each cultivars were sown in each replicate. After 10 - 15 days from the sowing, the percentage of germination was estimated, and samples of leaves were collected for RNA extraction and then changed to the cDNA. B - actin gene that consider endogenous control and salt tolerant gene TaGSK1 were amplificated by using PCR technique to discover the gene and by QPCR to estimate gene expression by determine the CT (Cycle Threshold) value for B - actin and TaGSK1 genes in wheat plants of the studying cultivars. Number of DNA dilutions of 189bp molecular weight that extracted from agarose gel were used to determing CT value for each dilution. Standard curves were drawn to find out value of PCR Efficiency which was used for gene expression for the salt tolerant gene TaGSK1.The results of germination percentage (%) showed that there were high differences between the two salt tolerant cultivars (Tigris and Euphrates) and 2H genotype and local cultivar (Tamooze 2). Euphrates cultivar gave 100% germination percentage, and the Tigris cultivar and 2H genotype gave 89, 86% germination percentage respectively at 25ds/m. whilst the local cultivar gave zero germination percentage at the same level of salinity. At 15ds/m level, also the Euphrates cultivar gave 100% germination percentage while the Tigris cultivar and 2H genotype gave 96, 94% germination percentage respectively as compared to Tamooze cultivar that gave 13% germination percentage. All the cultivars have 100% germination percentage at 0.0ds/m level. The conclusion of this result is the two cultivars (Tigris and Euphrates) and 2H genotype more salt tolerance than local cultivar at this growth stage which more salt sensitive than others growth stages. The results of PCR reaction were also indicated that Tigris and Euphrates cultivars and 2H genotype have salt tolerant gene TaGSK1, while this gene did not exist in the local cultivar. There were two bands of TaGSK1 gene that have 189bp and 404bp molecular weight in the Tigris and Euphrates cultivar and the genotype 2H, while the local cultivars have only one band that have 404bp molecular weight. These results were indicated that 189bp molecular weight of this gene is responsible for salt tolerance character in these cultivars.The results of QPCR reaction also were revealed that there is difference between the cultivars in their gene expression. Tigris and Euphrates cultivars and 2H genotype gave the highest gene expression at 15ds/m and increased at 25ds/m as compared to 0.0ds/m. At the second level 15ds/m the gene expression of the two cultivars and genotype was 0.8682, 0.8190 and 0.8688 respectively, and at the third level 25ds/m was 1.656, 1.3176 and 1.2665 respectively, while at the first level 0.0ds/m was less than the other 15, 25 ds/m as compared to local cultivar that the gene salt tolerant (TaGSK1) have no gene expression at the same salt levels. This result indicated that the local cultivar does not have salt tolerant gene TaGSK1. From these results we can revealed that TaGSK1 gene was found in the Tigris and Euphrates cultivars and 2H genotype, and this gene can be considered from high salt tolerant gene, because it gave the highest gene expression at the highest salt level 25ds/m. Therefore this gene help the plant to tolerate salt stress and grow very well. The results also showed that the two salt tolerant cultivars (Tigris and Euphrates) and the salt tolerant genotype (2H) proximately have the same salt tolerance degree, so they have proximately the same gene expression as compared to salt sensitive local cultivar which have no salt tolerant gene TaGSK1. This gene is good indicator for salt tolerance at high salinity levels 15, 25 ds/m in these cultivars and genotype.

Abstract: الصرع هو حالة مزمنة تتميز بنوبات متكررة دون سابق انذار، سببها خلل في نقل الاشارات الكهربائية داخل الدماغ، وعقار Levetiracetam (LEV) من العقاقير المضادة للصرع، ذو خصائص دوائية ملائمة وتظهر فعاليته في تحسين السيطرة على النوبات، ويكون امتصاصه في البلازما سري | Epilepsy is a condition characterized by recurrent abrupt seizures episodes caused by the defect in the transmission of electrical signals to the brain. LEV is one of antiepileptic drugs which has appropriate pharmacological properties and show its effectiveness in improving the control of the epileptic seizers, its rapid absorbance, and its excretion through the kidneys by glomerular filtration and it is re - absorption into the tubular portion.Kidney arise from intermediate mesoderm and it consists of three execratory organs in all vertebrates : pronephros which is transient and present in all vertebrates, mesonephros which also present in all vertebrates embryos and their activity depends upon the type of embryo, and metanephros which is the functional kidney during life after the embryogenesis in reptiles, birds and mammals. The first signals for kidney initiation in albino rat embryo take place in the 10th days of pregnancy. The current study is designed to demonstrate the effect of LEV (350 mg/kg/day) on the kidney development of Albino rat fetus from the age of 8 - 18 days of pregnancy and its effect on the kidneys of the 3 and 7 days aged newborns. In addition to its effect on pregnant rat kidneys treated with the drug for 17 days. Hundred pregnant Albino rat (Rattus rattus) are enrolled in this study, classified blindly to 50 control and 50 pregnant rats are orally treated with LEV (350 mg/kg/day). The histological results of the current study revealed that there is no effect on embryonic kidney in fetuses aged 9 days of pregnancy, whereas, the pronephros of the fetuses aged 10 days shows death of the cells in comparison to control group. Moreover, the kidney of the 11th aged fetuses showed degeneration of the mesonephric duct represented by decrease cellular mass, death and hypertrophy of some cells comparing to the cells of control group. Concerning the kidney of the 12th aged fetuses and subsequent days, there is degeneration of the epithelial cells of the metanephros duct, their detachment from the basement membrane and their congestion in comparison to the cells of the control group. The kidney of the 13th aged fetuses showed swelling, damage for some of the epithelial cells of the glomerulus and collecting tubules, accumulation and shrinkage of glomerular cells, damage, death, and detachment of some collecting tubules cells demonstrated in the 14th aged fetuses. There enlargement of capsular space in addition to the most previous defects was seen in the 15th aged fetuses in comparison to the control group. Most of the previous defects are seen in the 16th, 17th and 18th age fetuses. Scanning electron microscope revealed nuclear enlargement of the podocytes found in the visceral layer of the renal corpuscle of the 16th aged fetuses (mean diameter 64.6 µm compare to 39.2 µm of the control group). Regarding the kidney of 3rd and 7th aged newborns, the histological defects seen in the latest aged fetuses was also seen and there was statistically significant differences (p?0.05) between the diameters mean of the glomerulus of the 3rd and 7th aged newborn. Whereas, there was no significant difference in the diameter of the kidney tubules of 3rd but there was significant difference of the 7th aged newborn. Regarding the kidney of the 17th day treated pregnant rat, there was enlargement of the capsular space caused by accumulation, and degeneration of glomerular cells characterized by loss of the nucleus, shrinkage of the glomeruli, and atrophy of most of them. Loss of the nucleus and detachment of the cells, and swelling of most of the collecting tubules.

Abstract: تم الحصول على (20) عزله لبكتريا المكورات المعوية البرازية من اصل (135) عينة جمعت من مستشفى مدينة الطب ومستشفى الكندي وهي كما ياتي (15 عينة الادرار, 60 عينة دم, 50 عينة من قنوات الجذر للاسنان و10 عينة من الحروق).اختبرت الحساسية لهذه العزلات العشرون لـ 11 | Clinical sampling was carried out between September and December 2013, Twenty Enterococcus faecalis isolates were obtained from 135 clinical specimens. The samples included of patients in Medical City Hospital and Al - kindy Hospital (15 urine, 60 blood, 50 root canal and 10 wound swabs) Antibiotics susceptibility test for 20 isolates was done against 11 antibiotics, it was revealed that the isolates showed multi drug resistance were (18) isolates. The vancomycin susceptibility was determined by the minimum inhibitory concentration (MIC). Resistant and intermediate resistant to vancomycin was distributed among isolates at a ratio of 65% and 20%, respectively. Imipenem was found to be the most bactericidal agent against E. faecalis isolates E. faecalis virulence factors were detected phenotypically, The results showed that all isolates (100%) were hemolysin, protease and aggregation substance producer. 30% of isolates showed an ability to produce gelatinase. While (40.7%) of the isolates were a lipase producer. The results of the tube method showed that all E. faecalis isolates (100%) were slime layer and biofilm producer but the amount of adherent layer were different among the isolates ranged from strong to moderate and weak.The extracted DNA was subjected to Polymerase chain reaction (PCR) technique in a monoplex pattern to amplify the virulence factor Enterococcal Surface Protein (esp) which is chromosomal, results of this investigation showed that 20 (100%) E. faecalis isolates gave the amplicon size 933 base pair for the esp gene.The genetic determinants of Vancomycin - Resistant vanA and vanB genes were amplified using monoplex and multiplex PCR techniques in order to identify vancomycin resistant (van+) and sensitive (lacking van) among (13) E. faecalis. The vanA, vanB genes were detected in 11 and 4 E. faecalis isolates, respectively. The results of monoplex and multiplex PCR revealed that the molecular weight of vanA and vanB genes were 550 and nearly 600 bp, respectively. The results revealed that the vanA and vanB amplicons have a genetic variation in their molecular weight during the electrophoresis of PCR product.

Abstract: ان اضطرابات طيف التوحد هي مجموعة من الظروف التي تتميز بضعف في التواصل الاجتماعي ونمطية في السلوك. يختلف الاشخاص المتوحدين اختلافا كبيرا في التطور المعرفي والتي يمكن ان تتراوح من فوق المتوسط الى العجز في التفكير. رغم ان اضطرابات طيف التوحد هي تورث بشكل كبي | The autism spectrum disorders (ASDs) are a group of conditions characterized by impairments in reciprocal social interaction and communication, and the presence of restricted and repetitive behaviors. Individuals with an ASD vary greatly in cognitive development, which can range from above average to intellectual disability (ID). While ASDs are known to be highly heritable (~90%), the underlying genetic determinants are still largely unknown. The research studies correlate between Contactin - associated Protein - Like 2 (CNTNAP2), Interleukin - 1 Receptor Accessory Protein - Like1 (IL1RAPL1) genes and ASDs. This study includes forty autistic patients and forty non autistic children as control groups (twenty unaffected sibling and twenty unrelated children). The age of autistic and non autistic children was ranged from 3 to 10 years. Blood samples of autistic patients were collected from Rahman specialist centre for the care and service autistic children in Baghdad. DNA was extracted from blood samples for molecular detection of CNTNAP2 and IL1RAPL1 mutations associated with ASDs by the use Polymerase Chain Reaction (PCR) technique and sequence analysis. PCR reaction was performed to amplify exons (14, 17 and 20) of CNTNAP2 gene that encode to CASPR2, a member of the neurexin family which functions in the nervous system as cell adhesion molecules and receptors. The PCR results revealed that identical bands related to the CNTNAP2 exons were present in all samples. Therefore, five samples (four from autistic patients and one from control sibling) were selected for genotype analysis of CNTNAP2 exons (14, 17 and 20) by direct sequencing. Genotype analysis revealed that there were no any variants in CNTNAP2 exons, but it shows that four different mutations were identified in non coding region (introns) of the CNTNAP2 gene. These mutations were seen only in autistic patients but absent in control sample. Three of these mutations are single nucleotide polymorphisms (SNPs) (rs3779031 A/G in 2118282 position, rs3779032 A/C in 2118436 position and T/G in 2117905 position). The other mutations were deletion in one nucleotide (Del A/ - in 2117901 position). SNP rs3779032 A/C are located at intron 21 while other mutations are located at intron 19. The current study showed that two common SNPs (rs3779031 and rs3779032) in CNTNAP2 were strongly associated with ASDs, where the frequencies of these SNPs were relatively high. SNP rs3779031 identified in two autistic patients while rs3779032 identified in three autistic patients from four unrelated families with ASDs. PCR reaction also was performed to amplify exons (3, 4, 5, 6, 7, 8 and 9) of IL1RAPL1, a gene implicated in calcium - regulated vesicle release and dendrite differentiation. The PCR results show a large intrgenic deletion (Deletion of exons 3 and 4) in six autistic patients, two of these patients were twin. This deletion may be incomplete penetrance due to phenotypic heterogeneity of these patients. This study provides evidence of the role of genetic factors in the etiology of ASD and the important CNTNAP2 and IL1RAPL1 genes mutation of pathogencity ASDs.

These gases include Monoxide Carbon, Dioxide Carbon and Sulfur Dioxide (CO, CO2, SO2). This study also aims at investigating the quality of rainwaters which are falling on the area of the study, and conducting some biological tests for them. Moreover, this study aims to identify the effect of vehicles productions upon blood physiology and the construction of some persons who are dealing with them. The samples have been collected during September 2010 till May 2011, and then classified in terms of age and duration of exposure. Alsuqoor Village represents the control group. A sample has been collected from healthy, non - smoker males. The concentrations of some polluted gases emitted from exhausted vehicles are identified. They are significantly high in comparison with the control group and during the whole chapters of the study. The highest level of pollution value is recorded by the gases (CO, CO2, SO2) and at (p< 0.05) level in Albasha Street during the Autumn, whereas the lowest value is recorded in Alzuhoor Street, during the Winter ( ). In addition, some of rainwater characteristics have been measured such as, (Ph, electrical m and the amount of plankton in water). The obtained results show that there is a significant decrease in PH concentration and a significant increase in EC concentration. Moreover, results indicate that the highest concentration of the clot material is in Alarbaeen Street ( ) whereas, the lowest concentration is in Alzuhoor Street ( ). The level of some rare elements has been measured in the blood serum of those who are exposed to (lead, cadmium) and in different periods of times. A significant increase is recorded in the levels of those elements, in comparison with the control group (ps 0.05). As for effect of blood components of those who are exposed to pollutants, the concentrations of both (Hb, Pcv) have been decreased with an increase in the concentrations of (the number of red and white cells and ESR) in comparison with the control group at level (P<0.05). It is also noticed that there is a significant increase in the number of the neutral and acidic white blood cells with a significant decrease in the number of the moral white blood cells at the lymph cell, in comparison with the control group. Results also show that there is a significant increase (P<0.05) in the level of each (Cholesterol, Triglycerides, and Lipoproteins with low density LDL) with decreased concentrations of (High Density Lipoproteins HDL) whereas, there are no significant difference in the concentrations of (Low density Lipoproteins Very high density VLDL). Concerning the concentrations of (Urea, Uric acid, Kreatenin) there is a significant increase (P<0.05) in comparison with the control group and for all the groups of the study. The pollutants have an effect upon the average number of enzyme in the blood serum. There is a significant increase in the average of the enzymes that carry amino (ALT, AST) an enzyme phosphate in comparison with the control group. The study has also shown a significant increase in the Monoaldehyde level MDA and decrease in the glutathione level, under the effect of various pollutants. It is noticed that the blood components as well as the biochemical variable are greatly affected as the period of exposure extended and these biochemical variables become very great. Therefore, most of the differences are existed in the third group whose ages range between (40 and 49) with 9 years of work, followed by the second group whose ages range between (30 and 39) with 7 years of work. Then comes the first group whose ages range between (20 and 29) with 5 years of work, in comparison with the control group

The highest infection with amebic tissue and G.lamblia parasitism that came from country were (9.10%, 60.82%) also noticed that the raise of infection with E.histolytica and G.lamblia parasitism among children that their mothers had low education less than intermediate (illiteracy and intermediate) as follows (29.8%, 36.5%) for the children were infected with G.lamblia parasitism. And for children that infected with E.histolytica parasitism among children that their mothers had low education less than intermediate (illiteracy and intermediate) as follows (4.29%, 36.5%). The percentage for infants for the first 2 years had been infected with E.histolytica and G.lamblia parasitism for the first 2 years that they depend on industrial suckle as follows (7.73 %), (41.2%). The percentage for infants above 2 years had been infected with E.histolytica and G.lamblia parasitism for the first 2 years that they depend on industrial suckle as follows (9.10%) , (48.96%) also noticed the raise of infection with E.histolytica and G.lamblia parasitism among the children that was the river is the water source, the percentage were as follows (8.59 %), (51.54%). And the infection with E.histolytica and G.lamblia parasitism among the children that was the pipes system is water source the percentage were as follows (6.87%), (23.98%). the infection were very high with E.histolytica and G.lamblia parasitism among the children that lives within crowded families, the percentage was (12.54%), (55.67%). and the infection with E.histolytica and G.lamblia parasitism according to the seasons was dissimilar, and the highest recorded infection with E.histolytica parasitism in winter as follows (35%) and the lowest infection was (11.3%) in summer. Meanwhile the highest infection with G.lamblia parasitism (8.41%) in summer and (1.20%) in autumn.The second part studied the effect of alcoholic extraction from lantana camara plant on growth of E.histolytica and G.lamblia parasitism on mice. The effect was obvious for the alcoholic extraction for the mentioned plant for all extraction on the E.histolytica and G.lamblia parasitism in general, but the most effectiveness extraction to destroy the E.histolytica and G.lamblia parasitism was 1000 mlm/kgm from the alcoholic extraction for the plant lantana camara

Abstract: يتوارد الى مصرف الدم ضمن دائرة صحة ديالى العديد من الاشخاص الذكور, يوميا للتخلص من زيادة الدم (كثرة الحمر) , وللتعرف على بعض جوانب هذه الحالات المرضية : تم جمع 90 عينة دم من هؤلاء المرضى (54 مدخن, 36 غير مدخن) قورنت مع 40 عينة دم لاشخاص اصحاء, تراوحت اعم | Many male persons come every day to the blood bank labeled within Diyala Health Directorate to get rid of blood ratio increase(polycythemia). To shed light on this phenomenon, 90 blood samples are collected from these patients (54 smokers, 36 nonsmokers) and they are compared with 40 blood samples of healthy persons within the age range of (18 - 79 years) in the period ranging from Decembar.1st. 2012 to March.1st. 2013. A Hematocrit (HCT) criterion of 52% is used in the study as a sickness criterion.The present study was conducted to : 1. Measure the red and white blood cells and platelet counts (complete blood picture).2. Measure antioxidant the concentration vitamins C, E in addition to vitamin D3 and Glutathione (GSH).3. Measure the levels of the Malondialdehyde (MDA). Results of the statistical analysis show a significant increase(p<0.001) in Red blood cells, Hematocrit, a significant increase in the White blood cells (p<0.05), a significant increase(p<0.001) in the (Neutrophils, Monocytes and Esophils) while the mean of Lymphocytes and Basophils counts show a significant decrease (p<0.001) compared to the control group. Blood platelet did not show significant variations between the control and sick patient groups. Upon splitting the patients group to smokers and nonsmokers, results of the statistical analysis reflect a significant increase of (p<0.05) in the Hemoglobin of nonsmokers with polycythemia compared to the control group and to smokers. The platelets count did not mirror any significant variations between the patients and control groups despite the increase in platelet numbers in persons with polycythemia group that are nonsmokers and a decrease in smokers patients. Results of the statistical analysis also show a significant increase of MDA levels in patients with polycythemia (p<0.001) compared to the control group especially in the nonsmokers which signals an increase in lipid peroxides and reactive oxygen species. Results of the statistical analysis show a significant decrease of (p<0.001) in the levels of vitamin C in the patients with polycythemia, the smokers as well as the nonsmokers polycythemia sub groups compared to the control group which refers to the notion that the vitamin E free radical attacks vitamin C to remake vitamin E. in this case vitamin C is consumed and vitamin E will be remodeled. There is a significant decrease (p<0.001) in the mean vitamin D3 in patients with polycythemia compared to the control group. Vitamin D3 has an impact on Red and White blood cells inside of the bone marrow, this matter sheds light on the probability of this impact of vitamin D3 on the pathogenesis of polycythemia. The results of statistical analysis did not show significant differences in the means of vitamin E and GSH levels. The present study revealed a positive relationship between vitamin D3 levels and Red Blood Cells counts, In addition there was a negative correlation of vitamin D3 with Mean Corpuscular Volume (MCV) in total polycythemia group and polycythemia smokers sub groups.

Abstract: Phytoremediation is defined as the use of green plants to remove pollutants from the environment or to render them harmless. Phytoremediation process can be classified based on the contaminant fate as; Phytoextraction, Phytotransformation, Phytostabilization, Phytodegradation, Rhizofiltration. In this work, the phytoextraction process was employed. A piece of land in the Botanical Garden at the University of Baghdad with an area of 25 m2 was prepared to plant the barley plant. Then, seeds of barley of type "Samir", which is an Iraqi kind that suitable for cultivation in Iraq, have been seeded. For U and Cs experiments, soil was mixed with a limited quantity of each U isotope for three different concentrations; 152 Bq/kg, 95 Bq/kg and 81 Bq/kg and for Cs106.5 Bq/kg, 79 Bq/kg and51 Bq/kg. For NPK and Urea experiments, different concentrations were tested to establish the requirements of these experiments. The LB4100 - W counting system includes the most complete data analysis software package was used to measure and calculate the alpha and beta concentrations and subsequently the overall activity concentration of any studied sample. Samples were prepared by following the Indian Standard method. For U, the experiment achieved by dividing it into four groups that differ in the spent time of agriculture in contaminated and clean (reference) soils. The results illustrated that the phytoextracted of U with planted period in contaminated soil, which were 31, 50, 63, 34 days, were 36.22, 54.84, 76.24, and 66.30 Bq/kgm, respectively. However, the 4th group differs comparing with other groups in the spent time of cleaned soil, which was 73 days. For Cs experiments, the work grouped similar to U experiment. The results of Cs phytoextraction showed that the absorbed Cs were 54.34, 100.69 and 109.07 for spent times in contaminated soil; 23, 43 and 57 respectively. Furthermore, barley plant has significant ability to phytoextract U and good ability to phytoextract Cs for all the three different concentrations. Besides, the results illustrated that the increase in the planted time in contaminated soils led to increase the quantity of phytoextracted isotopes. The results of adding K fertilizer showed a decrease in the ability of barley to absorb U, while the addition of urea enhanced the ability of barley. Finally, the following conclusion can be drawn from the present study that : barley is a good tool to phytoextract Cs rather than U and the use of urea fertilizer is suitable for enhanced the phytoextraction process.
