It also included the preparation and detection of two hybrid nano compounds, one of them from the disinfectant chlorhexidine and the other from the tannic acid. The inhibitory activity of the nano disinfectant was assessed against the isolated bacteria in this study also, the antioxidant activity of the hybrid nano tannic acid was identified and the results showed the following : 1 - As a total 32 samples were taken from burned patients hospitalized in the burning ward Imam Al - Hussien medical city in Sacred Karbalaa governate. It had been obtained 8 isolates (34.78) % from Pseudomonas spp., 7 of them were Pseudomonas aeruginosa and one was P. oryzihabitans , 4 isolates (17.39) % were Acinetobacter baumannii, 4 isolates (17.39) % were Klebsiella pneumoniae, and one isolate (4.34) % of Proteus mirabilis, Escherichia coli, Serratia liquefaciens and Chryzeobacterium meningosepticum and two isolates (8.69) % of Staphylococcus aureus in addition to one isolate (4.43) % from Candida guilliermondii yeast.2 - Chlorhexidine disinfectant and tannic acid were used in preparation of the two hybrid nano compounds after intercalating each of them on layers of double hydroxide (Mg/Al - LDH). FT - IR spectrum studies has shown the appearance of specific chemical groups and the disappearance of others while the spectrum of x - ray(XRD) has shown the appearance of new levels of diffraction in the spectrum of the hybrid nano disinfectant Mg/Al - CHX - LDH and the spectrum of the hybrid nano tannic acid Mg/Al - TA - LDH as compared to the spectrum of the Mg/Al - LDH, which indicate that the two prepared compounds under study is a nano hybrid compounds. Results of the scanning electronic microscope has shown, the change in the shape of the surface of the nanohybrid compounds that prepared above as compared to the layer of double hydroxide. It turns out from the results of the examination with the use of Atomic Force Microscope (AFM), that the diameter of the particles of hybrid nano disinfectant and hybrid nano tannic acid were (121.66 and 77.70) nm, respectively. 3 - The inhibitory activity of the hybrid nano disinfectant Mg/Al - CHX - LDH and the free disinfectant (Free CHX) has been studied and the results revealed followings : a. The hybrid nano disinfectant has the highest inhibitory activity against the two bacterial isolates P. aeruginosa (11 and 23 - A) with an inhibition diameter of 24 mm for each, while the inhibition diameter for the free disinfectant was 23.5 mm against the isolate P. aeruginosa 4 - C.b. The hybrid nano disinfectant showed the highest inhibitory activity against the two isolates A. baumannii (16 - A and 31 - A) with an inhibition diameter of 18 mm for each, while the highest inhibition activity for the free disinfectant was against the isolate A. baumannii 22 - B with an inhibition diameter of 19.5 mm.c. The hybrid nano disinfectant showed the highest inhibitory activity against the isolate K. pneumoniae (16 - B) with an inhibition diameter of 24.5 mm, while the highest inhibition activity for the free disinfectant was against the isolate K. pneumoniae 15 - B with an inhibition diameter of 24.5 mm also.d. The highest inhibition activity for the hybrid nanoic disinfectant against each of bacteria P. mirabilis and E. coli with an inhibition diameter of 23.5 mm, while the highest inhibitory activity for the free disinfectant was against the bacteria E. coli with an inhibition diameter of 24.5 mm, while the bacteria C. meningosepticum was the least affected among the other types of the isolated bacteria with an inhibition diameter of 8 mm and it was resistance to the hybrid nano disinfectant.e. The highest inhibition activity for the hybrid nano chlorhexidine was against the isolate S. aureus 21 with an inhibition diameter of 28.5 mm, while the highest inhibition activity for the free chlorhexidine was against the isolate S. aureus 22 - A with aninhibition diameter of 31.5 mm.f. The inhibitory activity of both the hybrid nano and the free disinfectant against C. guilliermondii yeast was closely to each other with an inhibition diameter of (28 and 29) mm, respectively.4. The study of antioxidant activity confirmed the following : a. Using free radical scavenging method, the IC50(Half maximal inhibitory concentration) value against ABTS free radical were at 10 µg /ml for free tannic acid while it was at 125 µg /ml for the hybrid nano tannic acid Mg/Al - TA - LDH.b. Measurement of ferric ion reducing power revealed that free tannic acid had reducing power greater than that of the hybrid nano tannic acid

One hundred samples were collected from people who suspected to infect with fungal skin disease from patients coming to Al - Diwaniya teaching hospital from beginning of October 2013 till the end of May 2014. These samples from (skin, hair and nail). All samples that taken from patient were subjected to direct examinations by using wet touch of (KOH 10%) solution. At the same time the samples were grew on sabroud media to determine the type of fungal skin diseases of human. The direct examination shows positive results of 72 samples which represent 72% while for laboratory growth results, its shows 65 samples with positive results 65%. There are three types of Trichophyton fungus had been isolated which are T.rubrum 28 isolates, T.mentagrophytes 16 isolates and T.schoenleinii 4 isolates and there was one type of genus Microsporum which is M.canis 24 isolates. The results show that Tinea corporis infection is the common and its more among females than males where it is 26.39% and 13.89% respectively, then Tinea capitis which is 19.4% in males which is higher than in females which represents 13.89% while Tinea unguium was in females more than males which was in females 16.67% while in males 9.72%. The percentage of fungal skin infection was differ according to the location where the number of infections in the rural area for all types of Tinea were more than the number of infection in the urban area where the number of infected people with Tinea corporis was 18 which represent 25% while in the urban the number was 11 which represent 18.28% while the number of infected people with Tinea capitis in the rural area were 16 which represent 22.22% and the infected in the urban were 8 which represent 11.11%. While Tinea unguium the number of infected people in the rural 10 which represent 13.89% and in the urban 9 people which represent 12.5%. The diagnosis of isolated fungi depended on phenotype of fungal growth and microscopic examination, in addition to special tests for diagnosing skin fungal infections. Also the PCR was used for diagnosis and the work had been completed by using genotypic tree for fine diagnosis and detection the fungal species. The result were send to the genes bank site to be sure about the fungus type through comparison with the registered fungi in this site and by using MEGA6 program for genetic tree analysis of type (unweighted pair group method with arithmetic mean). The results of analysis shows clear converge of local Trichophyton spp. Isolates with Trichophyton rubrum in comparison with other types that appears in the genetic tree analysis while Microsporium diagnosed through genetic tree analysis of type (up GMA tree) and the result of analysis shows clear converge of local Microsporium spp. Isolates with Microsporium canis compared with other types of genetic tree analysis. The effect of silver nanoparticles that is used against growth of T.rubrum, T.mentagrophytes and M.canis. The results show that all the concentrations used were effective in stopping of growth of T.mentagrophytes when deal with the standard measure when dealt with concentration of 4 mg/l the more effective in stopping of radiating growth of the fungus. Regarding the fungus T.rubrum the concentrations of 4 mg/l more effective in stopping of growth while there was no difference for 1mg/liter concentration. Regarding the fungus M.canis, the mentioned concentrations had large effect on fungal colonization growth compared with the standard and this fungus more than other fungi affected by nano silver ions

Bacteriological culture identified fifty (80.33%) isolates as E. coli depending on cultural and biochemical characteristics as well as Api and Vitek 2 automated systems. However, 82% of isolates developed ? - hemolysis on blood agar plates.Susceptibility of all isolates against seven commonly prescribed antibiotics were investigated and 96, 82, 84, 92, 92, and 56%. of isolates were resistant to ampicillin, ampicillin/sulbactam, amoxicillin/clavulanic acid, cefalothin, imipenem, and meropenem, ceftazidime, respectively.Concomitantly, ? - lactamase production was detected phenotypically by disk replacement method. The results showed that 82% of all isolates have the ability to produce ? - lactamase. Interestingly, correlation coefficient between ? - lactamase and hemolysin production was 0.99.Using microtiter plate method, all E. coli isolates were tested for their ability to form biofilm. The results revealed that 36, 54, and 10% of isolates formed biofilm with variable thickness; weak, moderate, and strong, respectively.Alongside with previous findings, blaCTX - M - 2, blaVIM, blaTEM, and blaPER were identified in 18, 12, 10, and 4, respectively. Nevertheless, none of blaOXA - 1, blaOXA - 4, blaOXA - 30, blaIMP, blaCTX - M - 1, blaCTX - M - 9, blaKPC, and blaSHV. The isolate number 11 harboured the highest number of genes (blaTEM, blaVIM, and blaPER) among all tested isolates. Twelve albino mice was divided randomly into four groups comprising A through D injected with ceftazidime at sub MIC, E. coli 11, E. coli 11 with ceftazidime solution, and standard strain, respectively.Histopathological sections did not show any changes in respeuct to group A. however, group C suffered signs of infection less than those appeared in group B sections. Simultaneously, group D suffered intense histpathological changes more than other groups infected with resistant isolate.

From 61 patients by two samples per patient, also were collected 228 samples of stool from the laboratory of the Department of parasites by two samples of 114 patients for the period from January 2014 to January 2015. Where shown on biopsy results which were subject to examination by the rapid urease test (RUT) the presence of 60 (98.4%) cases, while there were 23 (37.7%) case of those bacteria being positive related to biopsy was not significant differences between the two tests performed. When the distribution of test results (RUT) and culture according to age group, it appear that the highest percentage of infection was in 50 - 41 age group that which showed the highest percentage on examination (RUT) of the number of infected at 16 (26.23%) cases, either in the culture technique number of infected at 9 (14.75%) cases. But when the results of each of the examination (RUT) and culture were distribution according to the sex of the patient's infection was the higher in the females than males reaching males 28 (45.90%) cases in females of 32 (52.46%) cases for examination (RUT). No significant differences appear between the sexes in terms of infected. While the males in 8 (13.11%) and in the case of females was 15 (24.59%) case for the culture technique it did not show significant differences between the sexes in terms of the patients. While taking stool samples to check the stool antigens, it was found that there are 76 (66.7%) cases diagnosed while the technology for the polymerase chain reaction gene cagA to 49 (43%) cases have significant differences between the tests performed. When distribution the results of each of the stool antigens and polymerase chain reaction technique by age group category the highest infected was in 46 - 55 the age group with the number of 23 (20.18%) people case for screening stool antigens. The test results of the technology polymerase chain reaction showed that highest rate of infection was in the 35 - 26 age group where the number of patients was at 15 (13.16%) case.The results of the stool antigens examination also showed that the infection rate among males was higher than females, 39 males (34.21%) and in the case of females has reached the number of 37 cases (32.46%) casesThat did not show significant differences between the sexes patient. The technical results of the polymerase chain reaction by sex has been the injury was higher in females than males reaching 22 in males (19.30%) cases, while in females was 27 (23.68%) cases did not show significant differences between the sexes in terms of the infected. The results of the study conclude that (RUT) and stool antigen test is the fastest in the detection of infection from the bacteria H. pylori and then comes beyond culture technique for biopsy sample and then polymerase chain reaction for stool samples

المستخلص: للفترة من اذار 2014 الى اذار 2015 تم جمع 1300 عينة سريرية مختلفة (عينات ادرار ومسحات جروح وحروق وعينات دم ومسحات من الفم والاذن والعيون بالاضافة لعينات البراز والقشع) من اثنين من مستشفيات محافظة بابل (مستشفى الحلة التعليمي ومستشفى بابل التعليمي للنسائية و| During the period between March 2014 and March 2015, a total of 1300 clinical specimens (urine, wounds, burns, blood, throat, ear, eye, stool, and sputum) were collected from two hospitals in Babylon province; Al - Hillah Teaching Hospital, and Babylon Hospital for Maternity and Pediatric. All specimens were cultured and 10 Acinetobacter baumannii isolates were obtained from clinical specimens in a percentage of (0.76%) distributed in blood 1 (0.6%), urine 2 (1%), wound infection 1 (0.75%), burn 5 (0.85%) and throat 1 (2%). This study was conducted to determine the occurrence of carbapenem resistant A. baumannii isolates obtained from Hillah hospitals. Isolates were identified according to API20E system and further confirmed using PCR technique. Antibiotics susceptibility was assayed by using disks diffusion method according to CLSI recommendations. All isolates revealed positive results with rapid iodometric test indicting the ability of beta lactamase production. Phenotypic detection of carbapenemase production was performed using the imipenem - EDTA disk and modified Hodeg's test (MHT). Then isolates were subjected to monoplex PCR targeting blaOXA - 51, blaOXA - 23, blaOXA - 24, blaOXA - 58, blaIMP, blaSIM blaNDM - 1, blaNDM - 2 and blaVIM genes, as well as, efflux pumps genes. One of the identified isolates (10%) was found to be imipenem, meropenem and ertapenem resistant, this isolate gave positive result with the imipenem - EDTA disk and (60%) of isolates were positive to MHT. PCR experiments showed ; all isolates were harbored blaOXA - 51 gene, four (40%) isolates were harbored blaOXA - 23 gene, three (30%) isolates were harbored blaOXA - 24 gene, four (40%) isolates were harbored blaOXA - 58 gene, five (50%) isolates were harbored blaIMP gene, six (60%) isolates were harbored blaSIM gene, two (20%) isolates were harbored blaNDM - 1 gene, four (40%) isolates were harbored blaNDM - 2 gene, while none of these isolates harbored blaVIM gene. The present findings suggest that emergence of (OXA - 23, OXA - 24, OXA - 58, IMP, SIM, NDM - 1, NDM - 2) carbapenemase producing A. baumannii clinical isolates in Hillah City hospitals. Also there are indicative appearance of efflux pump genes ; (50%) for Ade - A and Ade - B each other, (40%) for Ade - C, (80%) for all of Ade - R and Ade - S, (100%) for all of Ade - I and Ade - J, and (50%) for Ade - Y. All isolates of A. baumannii appear as MDR, while only one appear to be as PDR. The trans - mobility of resistant genes was examined by trans - conjugation experiment ; the results indicated that only blaIMP and blaOXA - 23 genes were transferred horizontally in the current study. In attempting to investigate any blaNDM gene variation the results showed some different than NCBI - Blast A. baumannii blaNDM - 1 and blaNDM - 2 it may as a unique genotyping.These results revealed that carbapenemase producing A. baumannii were detected in both phenotypic and genotypic methods (PCR). This underlies the importance of their accurate identifications and reporting to prevent the emergence of complete resistance to the most potent drugs against A. baumannii in Babylon province.

The result of laboratory culture were positive in 67 samples. Depending on their cultural, morphological and biochemical characterization of bacterial isolates : (37.31%) of them were identified as Streptococcus pyogenes bacteria and the diagnosis is confirmed by the use of Remel Rapid STR System. Whereas (34.33%) belong to S.parasanguinis, (11.94%) S.mitis, (11.94%) S.oralis and (4.48%) S.thoraltensis were identification of them are confirmed by using Vitek - 2 System also. As well as Sensitivity test for S.pyogenes cultures for some of the antibiotics done and the results revealed that all cultures were sensitive to tetracycline and chloramphenicol drugs 100%, while it was different in their sensitivity for other drugs. According to age (2 - 13) years revealed the highest percentage of infection for both male and female, however the percentage of acute and chronic tonsillitis was higher in males than females. In this study, during investigation of the antagonist action of lactic acid bacterial isolates against these pathogenic bacteria, results revealed that the method of L.acidophilus discs gave a high inhibition zones with a diameter of 11.3 mm, while L.fermentum discs yielded a high inhibition zones with a diameter of 7 mm 24 hrs following incubation in comparison with well diffusion method by using suspension of L.acidophilus produced a high inhibition zones with a diameter 7.25 mm 48 hrs after incubation. L.fermentum suspension produced a high inhibition zones with 10 mm diameter 24 hrs following incubation. Also the study included measurement of the inhibition activity for bacteriocins produced by L.acidophilus bacteria against the pathogenic bacteria S.pyogenes on nutrient agar by well diffusion method in which results revealed stability of the bacteriocins effects under different PH (4, 5, 6) with percent (100, 60, 50)% respectively for 24 hrs at higher stability and the highest stability of bacteriocins during PH was 4 with percent 100%, while it lost a lot of its activity with acidic PH less than 2 and basal pH more than 8. During the study the effect of Nacl, Kcl and MgSo4 with different concentrations (1 - 5%) with constant inhibitory effect for bacteriocins produced by L.acidophilus against pathogenic S.pyogenes, The result revealed that Nacl had little effect in inhibition zone with 1&2% concentrations. The salt MgSo4 and Kcl showed reduction in the inhibitory activity with 1, 2, 3% concentration, however the higher concentration of salt caused great reduction as 5% concentration led to loss of inhibitory activity for bacteriocins completely.Also this study showed light on the inhibitory effect of probiotics suspensions against the adhesion property of S.pyogenes after treated with L.acidophilus and L.fermentum.where the Result shown that L.acidophilus inhibit the adhesion of S.pyogenes with percent 68.92% either L.fermentum inhibit the adhesion of this pathogenic bacteria to epithelial cell with percent 30.28%. The study is consisted of showed the inhibitory action for suspensions of L.acidophilus and L.fermentum on biofilm formation by S.pyogenes, it was noticed the action of L.acidophilus in the side more than from the action of L.fermentum. During the study of the effect of suspension and filter of L.acidophilus and L.fermentum on the production of Hemolysin enzyme by S.pyogenes, it was noticed that the ability of suspension belong to L.acidophilus and L.fermentum to reduce the diameter of hemolysis zone which was beta type more than the ability of filter L.acidophilus and L.fermentum to reduce of the hemolysis zone which was beta type.

Only 51(31.875 %) Staph. epidermidis isolates were obtained during a period from September 2014 to January 2015, depending on some biochemical tests and VITEK2 system. The Staph. epidermidis was given (gram stain, catalase , urase) positive, (coagulase, manital fermentation, oxidase, motility) negative, non haemolytic to human blood with some exception, most of the strain were able to produce biofilm, and (100%), (64.70%), (74.50%) resistant to penicillin G, ampicillin, and amoxicillin respectively. The Staphylococcus species identified during study were 44 (27.5%) isolates of Staph. aureus, 5 (3.125 %) Staph. haemolyticus, 4 (2.5 %) Staph. saprophyticus, 8 (4%) isolates other Staphylococcus spp. such as Staph. hominis ssp. hominis, Staph. capatis, Staph. xylose, Staph. simulanus, Staph. lentus, and 48 (30 %) from unknown genera. To isolate bacterioghages from sewage water, several sewage water samples were assayed using plaque assay of double agar overlay as a source of Staph. epidermidis phages. The bacteriophages were described depending on plaques size and shapes, phage 1 was the most predominant and frequent in the bacterial lawn and able to infect other S. species such as S. aureus. It has been selected to study it is titer, latent, rise period, and burst size were calculated. The effect of temperature, pH , and NaCl ions on it is original titer were studied.The results revealed a gradual decreasing in the phage titer with increasing dilution number. Latent period extended to (30 minutes) , while rise period was started with (40 minutes) extending to (60 minutes) , burst size was 2.346. Each temperature at several incubation periods , pH , and NaCl ions was significantly varied depending on phage titer. The optimum temperature was 40 ° C, while the 80 ° C was represented the inhibitor temperature. L.S.D. at level (0.05) for interaction was 39.552. The pH 6.5 - 7.5 represented the optimal pH for the best phage activity while the phage titer beginning to declining in above and below this range of optimal pH, L.S.D. at level 0.05 was 17.898 , the optimum NaCl ions concentrations were (0.1 M and 0.25 M), while the titer was significantly decreased with increasing the NaCl ion concentration in the culture solution, the L.S.D. at level 0.05 was (10.696). In conclusion of this study found that Phage1 was considered as predominant phage because of their ability to infect other Staphylococci species such as Staph. aureus.

المستخلص: “The current research dealed with fourteen taxa belonging to the genus Ranunculus L., Family Ranunculaceae that grown in Iraq. The study included the gross general morphological and micromorphological characters, the Pollen grains also were studied and the chemical compounds (Flavonoids), Ecological and geographical distribution and taxonomic treatment have been done. Also botanical key was puted to separate the Taxa”.“General survey for the Phytogeographical districts where the taxa spread in, and the result was a large crowds of samples, and new locations of taxa distribution were recorded. The specimens in the Iraqi herbaria were studied after ensuring that it was correctly identified”. “Comparative morphological study was undertaken to all plants parts of taxa including the roots, leaves, stipules, flowering parts and fruiting parts. Charts, diagrams, tables were drawn and accompanying with natural images for different morphological characteristics, as well as the field images that are important for the study. This study showed that all the taxa of the genus were herbs that are annual or perennial. There was agreat important for the roots, stems and there Indumentum, the presence orabsence of stipules, shape and size and margin of basal leaves and cauline leaves and leafy bract, the shape of sepals and their numbers and their Indumentum, the numbers and shape of Petals and their colors, the number of Stamens and the colors of Anthers, the shape of ovary and their indumentum, presence or absence of style as it was very useful for the taxonomic identification and separation of the studied taxa. As well as the fruiting parts including the length of fruiting peduncle, the fruiting receptacle, the fruiting head and its shapes and their dimensions, the number of Achene Fruitlets and their sizes, colors and Beak shape. Also the surface configuration of the fruitlets Surface has been studied by (SEM) as it wae either hairy or tuberculate - hairy or Transversely rugose or muricate or reticulate or reticulate - minutly rugose or granular or granular - hairy or granular - hairy tuberculate or spinulose”.“The study of the micro - morphological characters of hairs, leaves epidermal cells and the stomatal complex, have a taxonomic importance of supporting the morphological characters in separation and identification of the genus taxa”.“The study show that the pollen grains have a taxonomic importance because of their difference in shape, dimensions, the wall thickness and their ornamentation. It was either apolar which was spheroidal and pantoporate, or isopolar which has different shapes in the equatorial view it was spheroidal, subprolate and oblate - spheroidal, it was either 3 - colpate, 4 - colpate or 5 - colpat.the colpate where either zonocolpate or syncolpate in the form of parasyncolpate. The ornamentation were verucate, echinateand scabrate”. “The chemical study also has an importance in separation of the genus taxa, six flavonoid compounds were diagnosed by using” HPLC wich are Kaempferol, Vitexin, Orientin, Quercetin, Iso - vitexin and Iso - orientin. According to the presence or absence of those structures cluster analysis where done for the results of the flavonoid compounds and the taxa where divided into groups that reveal the chemical relationships between them.dendogram where performed which also show the chemical relationships between the taxa by using UPGMA method and NTSYS program issue 21. the study shows that the presence and distribution of those compounds vary according to the variation in the plant distribution the study shows that some of the taxa have “the same compounds which enhance its belonging to the Ranunculus genus”. “Through field surveys and information installed on the herbarium samples, the taxa where distributed on their growth areas, and maps have been drawn for taxa distribution in the Iraqi natural geographical. Most of the taxa were distributed in N. and N.E of Iraq regions districts especially in MAM, MSU, MRO, and FBF districts. We notice that MSU district has a great number of the plants under the study as we found there are all the taxa accept one”. This study helps to detect distribution areas for some taxa that have been not mentioned in the Iraqi flora or other records which are R.kotschyi and R.trichophyllus var.trichophyllus. Also the study records distribution for the new species R.chius in MAM district which hasn't been mentioned in the Iraqi flora in this district before. Finally all the taxa were classified and the botanical key was done to separate them.

المستخلص: هناك مفهوم متنام يشير الى زيادة انتشار البدانة بين مرضى القلب التاجية Coronary heart disease (CHD), مما له الاثر الكبير في نشوء المرض ومضاعفاته, اذ يشابه عمل الخلية الدهنية adipocyteعضو الافراز الداخلي endocrine organ.ولمعرفة العلاقة بين البدانة وامراض | There is a growing concept that refers to the increased prevalence of obesity among patients with coronary heart disease. This has significant impact on the emergence of the disease and its complications as the work of the adipocyte resembles the work of the endocrine organ. This study comes to know the relationship between obesity and heart disease. To accomplish this, about 5cm3 of venous blood has been collected from 240 patients of coronary heart disease who are admitted to the resuscitation unit in Baquba Teaching hospital for the period 1st of December 2014 to1st of January 2015. The range of the patients' age is between 22 - 90 years old. The sample has been divided into three groups in accordance with body mass index and according to the classification of the American Institute. These groups are : natural weight from 18.5 - 24.9kg/m2, overweight from 25.00 - 29.9 kg/m2 and obesity30.00 kg/m2. The result shows that there is a significant rise in the fasting blood sugar, the total protein in serum and the systolic pressure with the rise of the body mass. While the level of the cholesterol, triacylgcerol and the remnant lipoprotein of the patient has not been affected with the different of the body mass. The patients with natural body mass index show significant rise in the total and direct bilirubin levels as compared with other groups with no significant differences among the groups in the levels of uric acid, urea, creatine, and phosphorus and iron ionic. We conclude that there is a correlation between the body mass index and the systolic and diastolic blood pressure.

The Study included the gross general Morphological characters and Micromorphological characters, also the Pollen grains studied and Anatomy, Chemistry, Enviroment and Geographical distribution and Taxonomic treatment, also botanical key was putted to separate the taxa. General survey for the Phytogeographical districts where the taxa of genus distributed, in order to detect the distribution of the studied taxa of the genus Onobrychis. Therefore many collections obtained and new locations of taxa distribution were recorded, the specimens studied, and correct the mistake naming specimens were identified and reidentified some miss identified specimens. A comparative morphological study was undertaken to all taxa plants parts include the root, stems, leaves, stipules, flowering parts and fruiting parts and drew charts diagrams, tables and accompanying, with natural images for different morphology characteristics, as well as the field images. This study indicates that the characters of Leaf, Inflorescence, Flowers and Fruit were collectively contributed in the separation and identification of taxa. The pollen grains have a taxonomic importance because their different shape, dimensions of polar and equilateral view and wall thickness. The anatomical study showed the importance of Taxonomic support to the morphological characters in the diagnosis and isolation different taxa, and this study showed different in the anatomical characters of leaf include the characters of Epidermis, Stomata and the characters of a cross sections in stems. The current study showed that the trichomes were very important taxonomic in isolate different taxa because their variation in density, dimensions and the shape of epidermis cells that the trichomes arise from them and dimensions of the epidermal cells and the nature of their walls. The current study identified nineteen protein - amino acids by using High - Performance Liquid Chromatography (HPLC) and the distribution of these compound was variable among various taxa of the genus and that was useful in isolation different taxa. and the aliphatic amino acids, Glutamic acid, Glycine, Serine, Arginine, Alanine, Tyrosine, Valine, Methionine, Isoleucine and Lysine had a wide presence in the studied taxa, which means that they belong to the same genus. The ecology and geographic distribution of the taxa were studied using area survey and information of herbaria specimens, maps have been drawn for taxa distribution in the Iraqi natural geographical provinces. At last, a taxonomic treatment has been carried out for the taxa of the genus Onobrychis, as well as a detailed key to isolate them.

For these purpose, A total of 150 clinical specimens (skin scrapings (80), hair fragments (60) and nail clippings (10)) were collected from 100 patients (70 males&80 females) whom clinically diagnosed with dermatophytosis after attendingto the dermatology and venereal diseases centre of Mergan Teaching hospital and private clinic in Babylon city from Feb. 2014 to May 2014. T. rubrum were isolated and identified using cultural, biochemical and physiological tests. Isolates were then subjected for confirmation by PCR, genotyping using RFLP - PCR, sequencing and registration of these sequences in GeneBank for obtaining accession numbers then phylogeny. The growth conditions, were tested, in addition to, the genetic expression of proteases (exocellular protease and endocellular aminopeptidase) were determined using Real - Time PCR. Out of 150 specimens, 24 (16%) isolates were dermatophytic fungi and only 5 (20.8%) of them belong to T. rubrum. The influence of cultural conditions in growth of T. rubrum showed that the 30 ?C, pH 6, SDA medium and 7 days incubation were the optimal conditions for its growth. Proteolytic activity of isolates of T. rubrum against casein as a substrate revealed an ability to produce protease in solid and liquid media after 14 days of incubation. This activity was varies according to the type of isolate where the isolate No.1 (isolated from skin) gave a high proteolytic activity (5.6cm) in solid media and (80.1U/ml) in liquid media in comparison with other tested isolates (No.2 - No.8). on the other hands, the 9 days of incubation, 30 ?C, pH 7 and 0.5% substrate concentration were the optimal condition for proteolytic activity of these isolates. The molecular tests confirmed that all tested isolates belong to T. rubrum with amplicon size (601bp) after amplification of ITS1 primers using PCR technique. While the RFLP - PCR technique showed the presence of two genotypes (I%II) belong to T. rubrum with subgenotypes (Ia - Id) and (IIa - IId) respectively. The relative quantification of proteolytic activity (exocellular protease and endocellular aminopeptidase) produced by T. rubrum genotypes were expressed by using Real - Time PCR after amplification of the target gene of ptotease and aminopeptidase in comparison with housekeeping gene (? - actin) as a reference gene. The results showed the up - regulation of gene encoded to exocellular protease than the down - regulation of endocellular aminopeptidase produced by T. rubrum in the presence of casein as a substrate. The internal transcribed spacer 1, partial sequence, 5.8S ribosomal RNA gene and internal transcribed spacer 2, complete sequence and 28S ribosomal RNA gene, partial sequence of local isolates of T. rubrum were used for sequencing, registration in Genebank - NCBI and phylogeny. Five accession numbers were recorded and available to NCBI, EMBL in Europe and the DNA Bank of Japan. These accession numbers were : KP979787, KP979788, KP979789, KP979790, KP979791. Phylogenetic relation between local strains and world strain showed a high identicasl with T. rubrum (GQ376105.1). This is the first study in Iraq which employed sequencing, registration of sequences in Genebank - NCBI and carrying out phylogeny of local and world strains of T. rubrum.

The patients groups were divided according to the clinical diagnosis to 50 patients infected with ocular toxoplasmosis (OT) and 54 patents with uveitis, in addition to these groups acontrol group was also included 96 healthy apparent persons without any infection in their eyes.Some epidemiological characters were studied like age, that showed a little effect on two groups OT (Mean of age 38.07 ± 15.14) and uveitis (Mean of age 35.1 ± 17.6). The two groups were found in range 20 - 40 year while the control group include individuals with different age due to the randomly collection. The occupation factor play arole in the prevalence of infection with highly significant differences (P<0.05) in (house wife, workers) with a percentages 35(70%) 35(64.8%) in OT and uveitis groups respectively but the control group expend to include house wife, workers and officers with a total rate 92.7%.The education level also showed significant differences (P<0.01) among the studied groups, the most of ocular toxoplasmosis and uveitis samples were found in highly frequency at the primary, intermediate and secondary educational level with total rate 74% and 77.81% respectively while the control group was found at the secondary and under graduate educational level in 77.1%. The residency character was also examined and no revealed significant difference (P<0.05).The infection path was also set by the presence of animals especially cats which ware existed leading to statistical differences, p? 0.01 for OT group with rate 18%. The visual activity character showed no significant difference (P?0.05) between the patients of OT and uveitis who affected their visual acuity in right eye while the doubling response was recorded for uveitis patients with rate 55.6% in comparable with OT patients with rate 38% for the left eye. The intra ocular pressure was normal in both groups and for both eyes without significant difference.Latex and ELISA IgG. IgM serological tests were used in this study. The results were showed that latex test is easier and it is appear that OT patients were diagnosis with 100%, while the uveitis patients didn't show any positive result. Control group showed that 21 individuals were infected with rate of 21.9%.ELISA - IgG toxo. antibodies confirmed that the infection rate of OT patients was 39 (78%) versus 11(22%) with negative result, while the study also confirm that uveitis patient that have OT disease was 12 patient from 54 case, 42 case didn't diagnosis for OT. The control group was re - evaluated showed 28 case with toxoplasmosis infection from 96 case which from the subclinical group. The antibodies levels were measure by international unit/ ml for all groups, the IgG level was 3.186 ± 1.703 Iu/ml in positive control group followed by OT patients with 2.927 ± 2.417 and uveitis group 0.637 ± 0.803, finally the negative control group 0.276 ± 0.163. IgM levels were low and its presence didn't have any positive case. This study also showed that there was a relation between the IgG level and the pathological effect on eyes which resulted from infection for both groups OT and uveitis, it was high rate 73.5% with 50 patient, for posterior uveitis causing significant differences (P<0.05) followed by anterior uveitis with rate 13.2%.As for the results of cytokines there was a high level of IFN - ? in positive control group 793.7 ± 3461.6 pg/ml followed by OT group 550.6 ± 210.6 pg/ml, the uveitis group that in infected with ocular toxoplasmosis and negative control recorded 524.1 ± 173.6 and 506.6 ± 104.6 pg/ml levels respectively, this rise in the level of IFN - ? cause a significant differences at (P<0.05) for OT, uveitis (non infected) and positive control groups. TNF - ? recorded arise of its level in positive control group 34.89 ± 12.29 pg/ml followed by OT group 32.24 ± 9.91 pg/ml then positive uveitis group 23.61 ± 12.91 pg/ml after them negative control 14.62 ± 5.43 pg/ml finally negative uveitis group with 7.76 ± 4.04 pg/ml.High level of 1L - 12 was gotin positive control group in a concentration 827.00 ± 224.25 pg/ml followed by OT group with 811.28 ± 179.40 pg/ml. An increase in 1L - 17A was recorded in positive control group with mean 327.65 ± 77.89 pg/ml while converged concentration in OT group 263.73 ± 47.48 and positive uveitis group 252.57 ± 61.55 pg/ml. The lowest level was in negative control group 421.6 ± 168.14 pg/ml. MCP - 1 showed a rise in its level in positive control group 274.09 ± 92.05 pg/ml and reduce in OT patients 217.68 ± 98.70 pg/ml, while the two groups negative and positive uveitis recorded levels 155.71 ± 99.51 and 132.60 ± 99.02 pg/ml respectively.

This study aimed to isolation and identification the species of Pseudomonas and metabolic efficiency test in the analysis of petroleum hydrocarbon compounds and measure the effectiveness of antagonism in resistant pathogenic fungi to tomato plant. Thirty four isolates were identified, the Pseudomonas spp. was the highest frequency with 22 isolates. These isolates distributed to 16 isolates of pseudomonas aeruginosa and 6 isolates of pseudomonas fluorescens. Also this study included isolation of two pathogenic fungi which were Alternaria alternate and Fusarium solani in tomato plant. Statistical analysis revealed significant differences at (p<0.05) between the bacterial isolates in their analysis of hydrocarbon compounds, when the optical density measurement as an indicator of the effectiveness of growth on hydrocarbon sources. All isolates showed different optical densities were highest isolation of pseudomonas aeruginosa isolated from urinary tract infections as optical density amounting to 0.23nm. Also showed an increase in electrical conductivity values for all isolates within the incubation period, the highest value to the hospital (1) isolate with 12.8 mc/cm in the third week of the incubation, But decreased in the sixth week to 8.7 mc/cm and all isolates showed a good effectiveness of electrical conductivity in the third week and noted significant differences (p<0.05) in electrical conductivity values for isolates compared with control of 7.2 mc/cm. The results of the DNA electrophoresis of the all isolates contain the two genes (C23O and rhIB) which they code for the production of hydrocarbon - degrading enzymes. In Bio - antagonism experiments noted that all isolates were inhibitory to the growth of two pathogenic fungi and stimulating the growth of tomato plants in glass and field experiments through increase germination, vegetative ratio and root length and increased weights with significant difference at (p<0.05)with seed treatment with fungus only. The best isolates increased in germination were pseudomonas aeruginosa hospital isolate and pseudomonas fluorescens generating isolate which had stimulated germination rate to 76% with significant difference when compared with the control of Alternaria alternata and Fusarium solani which germination rate was 36 and 40 respectively. Pseudomonas aeruginosa which isolated from soil was more efficient in increasing the length of the stem, the stem height was 7.53 cm compared with the control treatment with F. solani, the stem height was 5.7 cm. Pseudomonas aeruginosa hospital which led to an increase in the length of the total root to 3.66 cm compared with the control treatment with F.solani at 1.53 cm. The increase in fresh and dry weights of Total vegetative reached 0.64 gm and 0.065 gm respectively when the treatment of seed contaminated with F.solani fungus and pseudomonas aeruginosa hospital isolate compared to the control which the weights were 0.11 g and 0.011 gm respectively. The highest increase in fresh and dry weights of total root of 0.057 gm and 0.0072 gm respectively when treated seeds contaminated with the F. solani with P. fluorescens hydrocarbon contaminated soil isolate compared with control that the fresh and dry weights was 0.032 g and 0.0017 g respectively. The highest value of stem length registered when treating seed with A. alternata which was 7.5 cm when treating seed contaminated with A. alternata by P. fluorescens isolated from soil contaminated with hydrocarbon compounds. The lowest value of stem length was 7.3 cm for the treatment of seeds contaminated with the A. alternata by P. aerugionsa isolated from the drainage water compared with control treatment (seeds contaminated with A. alternata) which stem length was 6.33cm. As for the fresh and dry weight for total vegetation was the highest value of 0.8 gm and 0.793 gm respectively when the treatment of seeds contaminated with the A. alternata P. aerugionsa isolated from urinary tract infections and the lowest value of fresh weight was 0.61gm for total vegetation when treated seeds contaminated with the A. alternata by P. aerugionsa isolated from soil non contaminated with hydrocarbon compounds and 0.069 gm when treated seeds contaminated with the A. alternata by P. aerugionsa which Isolated from drainage water compared with control treatment which were 0.15 gm and 0.0014 gm of fresh and dry weight for total vegetation, respectively. As for fresh and dry weight of total root were the highest value 0.071 gm and 0.008 gm respectively, when the treatment of seeds contaminated with the A. alternata by P. fluorescens isolated from soil contaminated with hydrocarbon compounds. while the lowest value were 0.058 gm and 0.0065 gm when treated seeds contaminated with the A. alternata by P. aerugionsa isolated from soil non contaminated with hydrocarbon compounds compared to control treatment (seeds contaminated with the A. alternata only)which the fresh and dry weight values for total root were 0.046 gm and 0.0018 gm respectively. When antagonism study in the glass field, the highest percentage of inhibition of the growth of the F. solani on PDA and cetramide agar were 42% and 61% respectively, when treated with P. fluorescens generator isolate. While the bacterial antagonism with A. alternata on PDA media, the highest percentage of inhibition 51% when treated with the transaction P. fluorescens generator isolate on PDA media. Generally, the treatment of pathogenic fungi with biological control bacteria had reduced the percentage of infection and increase the percentage of germination.

المستخلص: ان من الحقائق العلمية الثابتة اليوم ان الفحص الروتيني للسائل المنوي يعد عاملا تنبؤيا اجماليا للقدرة الاخصابية للرجال، ولذلك فان حاجة متزايدة بدات تبرز لاكتشاف فحوصات وظيفية جديدة في عملية تقييم العقم عند الرجال. ان الهدف الاساس من هذه الدراسة هو تعزيز الج | It is a scientific fact today that routine seminal fluid analysis is a key predictor of male reproductive potentiality ; so that there is an increasing need for finding out other functional tests in the assessment of male infertility. The main goal of the current study is to consolidate the scientific and practical efforts concerned with male infertility assessment especially from immunological and genetic aspects. The study was carried out between January 2013 and December 2013 including one hundred (100) selected infertile men who attended the Fertility Center in al - Sadr Medical City in Al - Najaf Al - Ashraf Governorate, the study also included twenty (20) healthy volunteer fertile men as a control. Serum and seminal antisperm antibodies (ASA) were determined by ELISA (Enzyme Linked ImmunoSorbent Assay) technique ; sperm chromatin condensation was evaluated by aniline blue staining (AB) ; sperm DNA fragmentation (damage) was evaluated by toluidine blue staining (TB). The results showed that the incidence and concentration of serum and seminal plasma ASA in the infertile men were significantly (p<0.05) higher than that in control fertile men. The incidence and concentration of serum and seminal ASA were also significantly (p<0.05) higher in normozoospermic infertile patients than that in control fertile men. There was a high significant negative correlation (p<0.01) between the concentration of serum and seminal plasma ASA in the infertile men and sperm motility and progressive motility, the concentration of serum and seminal ASA also showed a high significant positive correlation (p<0.01) with sperm agglutination, and a significant positive correlation (p<0.05) with seminal WBC count. The results also revealed that there were no significant effects (p>0.05) for patients' age, infertility duration, ABO blood groups and smoking habits on the levels of ASA in the serum and seminal fluid, while higher significant increase (p<0.01) in serum and seminal ASA concentrations was observed in infertile patients with varicocele as compared with those without. The results have also revealed that the percentage of sperm with chromatin decondensation and DNA damage has shown a high significant (p<0.01) increase in infertile patients compared to fertile men. There was also a significant increase (p<0.05) in sperm DNA damage in normozoospermic infertile patients comparing with fertile men, but no significant difference (p>0.05) was found in sperm chromatin condensation between normozoospermic patients and fertile men. Both sperm chromatin decondensation and sperm DNA damage showed a significant positive correlation (p<0.05) with sperm morphology, and a significant negative correlation (p<0.05) with sperm concentration, motility and progressive motility. The present study also revealed that the level of chromatin decondensation has been affected by patients' age, infertility duration, smoking habits and varicocele. It was observed that the higher percentage of chromatin decondensation was recorded in patients older than 37 years, and in patients subgroups with infertility duration more than 15 years, it was also higher in smoker as compared with non - smoker patients and in those with varicocele as compared with those without. Similarly, the level of sperm DNA damage has also been affected by patients' age, smoking habits and varicocele. It was observed that the highest percentage of sperm DNA damage was recorded in patients older than 37 years. The highest level of sperm DNA damage was also seen in smoker patients as compared with non - smokers and in those with varicocele as compared with those without. In contrast, the effect of infertility duration on sperm DNA damage was not statistically different (p>0.05). The correlation and regression results recorded high significant correlations (p<0.01) between serum ASA and seminal plasma ASA, and between sperm chromatin decondensation and sperm DNA damage. However, there was no significant correlation (p>0.05) between the level of serum and seminal ASA and each of sperm chromatin decondensation and sperm DNA damage. The current study concluded that the defects in sperm chromatin status (chromatin decondensation and DNA damage), and the immunological disorders caused by serum and seminal plasma ASA may - at least partially - contribute to the etiology of infertility of the patients under study, even in those with normal seminal parameters. However, it seems that ASA affect fertility in a pathway that is different from that affected by sperm chromatin defect. It was recommended that both sperm chromatin staining techniques and ASA tests could be routinely used as complementary tests to diagnose infertility.

المستخلص: نبات الصبار Aloe vera L. من النباتات المهمة والتي تستعمل حاليا بشكل واسع في مجال صناعة الادوية ويضاف هلام الصبار الى اغلب مستحضرات التجميل مع بعض المواد الغذائية في جميع انحاء العالم, لذا تم دراسة التاثيرات السمية الخلوية والوراثية لتراكيز مختلفة من المس | Aloe vera L. is one of the important plants in the world.It is currently and widely used in pharmaceutical industry, and its gel in some time added to some foods all over the world. Therefore, the present study was conducted to evaluate the cytotoxic and genetic effects of crude, alcohol and aqueous extracts of Aloe vera gel toward the onion(Allium cepa L.) roots (as a biological system) exposure at different periods. Onions roots were treated with different concentrations of the extracts : 2% , 5%, 10%, 20% and 40% (v/v)of the crud extract , 5%, 10%, 20% 30% and 50% (v/w) of alcohol extract and the concentration 25%, 50%, 100%, 150% and 200%(v/w) of aqueous extract of Aloe vera gel exposed for different period (24, 48 and 72) hour. The investigation were focused on the effect of these extracts on onions roots length rate and some cellular properties (mitotic index, phase index, the percentage and type of chromosome aberrations, as well as a genetic study using Random Amplified Polymorphic DNA (RAPD) of onions roots treated with different concentration of this extracts. Results showed that all Aloe vera gel extracts had inhibit activity toward onion roots length rate. The inhibition associated positively with the increasing concentration. The effective concentration (EC50%) were 10% of the crude extract, 20% of the alcoholic extract and 100% of aqueous extract, indicating the effectiveness of the crude extract followed by alcoholic extract and then the aqueous extract. Cytological study showed that all Aloe vera gel extract revealed a significant decrease in mitotic index (MI%) of the onion roots cells compared with the control group, and the effect was positively associated with the increasing concentrations of the extract. However, the effect was independent on the exposure period. The concentrations 10%, 20% and 150% of the crude, alcohol and aqueous extract respectively indicated a reduction of the mitotic index to almost 50% of the control treatment. Therefore, this concentrations considered as sub - lethal concentrations for this extracts respectively while the higher concentrations than 30%, 50% and 200% of the crude, alcohol and aqueous extract which reduced the mitotic index to almost 22% of the control treatment were considered as lethal concentrations. The results also showed a significant decreases in prophase and an increase in metaphase in onion roots cells treated with extracts comparison with control treatment. Many of chromosomal abnormalities were appeared due to the treatments of the onion roots with different concentration of the extracts, the percent abnormalities was increased with the increasing concentration of the extract and exposure period. The most frequent of chromosome abnormalities were chromosomal stickiness, disturbed chromosome, chromosomal bridges, C - mitosis, vagrant chromosomes in addition to the other chromosomal abnormalities star telophase. The toxicity effect of Aloe vera gel were studded on molecular level by using random amplification polymorphism of DNA(RAPD). Ten random primers were used, seven of them gave polymorphic bands in all the studied samples and their molecular weights were ranging from 100 to 1600 base pair. The results of Random Amplified Polymorphic DNA (RAPD) showed significant difference in the number of DNA band and their molecular weight of the onion roots treated with Aloe vera extracts compare to control treatment. The high concentrations(higher than EC50%) of extracts were showed to be more effective on the DNA through the appearance or disappearance of larger number of DNA band in comparison with control. The genetic template stability (% GTS) was significantly decreased in DNA of onions root treated with high concentrations (higher than EC50%) of Aloe vera extracts, therefore the high concentrations of Aloe Vera extracts were considered to be genetically toxic. The genetic dendrogram was obtained using Jaccard factor of genetic divergence and the result showed segregation of the samples treated with heights concentrations (%40 200% and 50%) of crude, alcohol and aqueous extract from other samples and control treatment. Therefore, the RAPD method can be considered as an efficient method in detecting for assessment of genotoxicity of crude, alcohol and aqueous extract of Aloe vera gel.

المستخلص: عزلت 45 عزلة بكتيرية محليه من مجموع 30 نموذج تربه ملوثة بالمبيدات والتي جمعت خلال فترات زمنيه مختلفة ومن مناطق مختلفه في بغداد. اختبرت قابلية العزلات البكتيريه على تفكيك مبيدي الملاثيون والدورسبان. اجريت غربلة اولية وثانوية باستخدام وسط الاملاح المعدنية ا | Forty five local bacterial isolates were isolated from thirty different soil sample contaminated with pesticide, These samples were collected from different Baghdad regions at different periods. The bacterial isolates were tested for their ability to biodegrade certain pesticides (Malathion and Dursban). Primary and secondary screenings were carried out using solid Mineral Salts Medium (MSM) and Liquid (MSM) with 100 ppm Malathion and Dursban at 37 0C, pH 7. Twenty seven isolates resistant to Malathion and Dursban were isolated. Out of 27 bacterial isolates from different locations in Baghdad. Results from primary screening showed that the 10 isolates had good growth, 5 isolates gave moderate growth, 12 showed weak growth and only 9 isolates failed to show any growth.According to current results, 10 bacterial isolates were tested for their ability to biodegradation of Malathion and Dursban in liquid medium, However, secondary screenings results by using minimal inhibition concentration(MIC) revealed that only four bacterial isolates had the highest ability to degrade Malathion and Dursban and subsequently were identified as Pseudomonas putida, Esherichia coli, Escherichia hermanii and Staphylococcus vitulinus by Vitek compact system respectively.The optimum conditions (incubation period, pH, temperature) for growth and biodegradation of Malathion and Dursban were examined. The obtained results indicated that the best incubation period was after 7 days, pH =6 and favorite temperature was 350C.Measurement physicochemical properties for soil pH, temperature (C°), electrical conductivity EC (µs/cm) for both Dursban and Malathion concentrations(ppm) collected from six different locations within Baghdad city. Biodegradation of Malathion and Dursban in soil inoculated with different bacterial mono - cultures and mixed - cultures were investigated. soil pH, temperature, electrical conductivity, cations and anions, on the population of native Malathion - Dursban tolerant bacteria in the cultivated soils of six sites. The result showed that soil physical properties like temperature and electrical conductivity affect significantly to native Malathion - Dursban tolerant bacterial density. Similarly, the soil chemical properties like pH, cations and anions had more effect on the abundance of Malathion - Dursban tolerant bacteria in the soil. However, the impact of soil organic carbon, organic nitrogen and available phosphorus was very significant. The results of the present study can be utilized for the development of effective bioremediation process for pesticide - contaminated soil. Under optimal conditions, Malathion and Dursban degradation was measured by using GC - MS analysis. The results revealed that Pseudomonas putida was the best isolate for degrading Dursban by monoculture isolate (47.18%) , while mixed culture(P.putida and S.vitulinus) was the best in degrading Malathion and Dursban that gave 90.84% and 81.055% respectively. Results also indicated that the number of byproducts produced by mono and mixed culture of Malathion and Dursban biodegradation. Whereas the results obtained from GC/Ms analysis revealed that not detected of toxic byproduct Malathion and Dursban degradation by Pseudomonas putida and Staphylococcus vitulins respectively.Moreover, under natural conditions.The study tested the ability of selected bacterial isolates (P. putida and S. vitulins) in biodegradation of Malathion and Dursban, the results showed slower biodegradation by selected bacterial isolates compared with laboratory conditions but study showed a intermediet product like phenol, diethyl phosphorothioate and oxon.The GC - MS results showed that the number of metabolic intermediates formed during the degradation of Malathion by bacterial mixed - culture were relatively higher in number than by bacterial mono - culture.The mass spectra of malathion containing samples treated with bacterial mono and mixed culture showed no any known toxic intermediates. The result indicated that the two main degradation products resulted from bacterial degradation, namely malathion monocarboxylic (MMA) and malathion dicarboxylic acid (MDA), the first one may convert into the latter over time. Some other degradation products may occur such as ethyl hydrogen fumarate (EHF) but in negligible amount.The result indicated that the main degradation products resulted from bacterial degradation of dursban is trichloropyridinol(TCP) and then de - chlorinated into 2 - pyridinol.The mass spectra results obtained in this study showed that the dursban was degraded to many metabolites.The results suggested that the bacterial isolates were not forming any toxic intermediates but no any intermediate was identified till R.T. 22 minutes. This indicated that dursban is probably completely metabolized by the isolates into smaller intermediatesThe isolate Pseudomonas putida isolated from soil contaminated with pesticides was identified genotypic tests. Molecular typing was performed by RAPD - PCR and comparison of the results to other Pseudomonas isolates. The result shows that genotyping differences between isolates and found the convergent percent biodegradation between this isolates of both selected pesticide, although from these differences, there was no more effect to biodegradation, which means that the biodegradation of Malathion and Dursban not related to genotype

These compounds were characterized by the Infrared (IR) Spectroscopy, Nuclear Magnetic Resonance Spectroscopy (1H - NMR), Mass Spectra, and the results were virtually identical to what is expected. It has been determined LD50 for the two ligands - after dissolved dimethyl sulfoxide DMSO - and account for them safe therapeutic dose, reaching 0.14 g / kg and 0.24 g / kg, respectively. In order to see the effectiveness of the two ligands on the parasite compared with the infected group and treatment with a drug metronidazole, these two ligands have been administered orally the therapeutic dose each separately on two groups of mice which infected by the parasite Entamoeba histolytica. Three other groups of mice that non - infected have been also administered separately with the parasite first and second ligands and dimethyl sulfoxide, to see some of the side effects of these three compounds in comparison with the two groups of positive and negative control. At the level of probability (p ? 0.05), the results of statistical analysis show a significant variation, remarkable inhibitory effect of the number of cysts that reached the less impact to the second ligand rate about 2.9. in the seventh day of the injury and treatment. In the fifth day of the injury and treatment, the highest inhibiting effect of metronidazole was at a rate of 0, while in the seventh day of them, the first ligand was a compromise in effect, amounting to at a rate of 1.1. The Histological study of tissue of the cecum, liver and spleen showed a normal state for a negative control, and an occurrence of severe tissue changes in a positive control. In the cecum tissue, the mucosal was thin, and there were crashes in the crypts of Lieberkühn, with infiltration in inflammatory cells, as well as the expansion of the cells lining the crypts, and the disappearance of or crash submucosal layer, as well as severe hemorrhage in muscularis, and thickening in serosa. There was severe congestion of the blood vessel which was observed in liver tissue, as well as thrombus which appeared attached to the wall of the blood vessel, and infiltration of inflammatory cells out of the blood vessel toward the hepatic tissue, especially macrophages and eosinophils. It was also noticed the disappearance of hepatic architecture with degeneration of the liver cells and a clear sinusoids expansion. In addition to vacuolation of liver cells, that the tissue sections showed, with the occurrence of bleeding along the hepatic tissue. The changes in the spleen tissue represented in the occurrence of severe bleeding on the length of the lymphatic tissue of the spleen with infiltration of inflammatory cells, especially macrophages, and the happening of megakaryocytes. There is a remarkable improvement could be noticed in each tissues of cecum, liver and spleen of the infected groups and treatment with metronidazole and the first and second ligands. The improvement ratios were close to some extent : in the treatment group with metronidazole there was observation in tissue cecum to the occurrence of the four layers of its component, and the happening of a little bleeding which, with infiltration of inflammatory cells, and this is roughly similar to what shown by histological sections of two treatments by the first and second ligands. The liver tissue of the group treated with metronidazole showed the occurrence of radially arrangement obviously hepatic cells around the central vein, and liver cells with nuclei appeared clear and centralized with esinophilic cytoplasm, and hepatic cells proliferative as some binucleated hepatocytes, with a simple expansion to sinusoids and the proliferation of kupffer cells, the treatment groups with two ligands marked by the presence of a small clot within the central vein of the liver as well as reported in the treatment group with metronidazole. Tissues sections of the spleen tissue of infected mice treated group by metronidazole showed a clear proliferation of white pulp, which appears containing arterioles clear, white pulp is also surrounded by proliferation red pulp. And showed tissue sections of the group of infected animals and treatment by the first and second ligands as well as the proliferation of lymphocytes, with the presence of megakaryocytes.Showed the three groups non - infected by the first and second ligands and dimethyl sulfoxide, the lack of side effects on each of the cecum tissue, liver and spleen, except for a very simple infiltration of inflammatory cells from macrophages in the cecum of the group treatment by the second ligand

The samples were collected in cooperation with artificial kidney center in AL - Kut Hospital, AL - Kut city, Wasit Province, during the period from 1 /10/2012 to 1/5/2013. In order to study the physiological changes of renal failure patients before and after hemodialysis and peritoneal dialysis. The blood samples were taken from one hundered thirty four patients for this study.The patients in this study were divided into two groups according to the type of dialysis : 94 hemodialysis patients, 52 males with age range (21 - 69) years and 42 females with age range (20 - 70) years, 40 peritonial dialysis patients, 24 males with age range (21 - 60) years and 16 females with age range (23 - 63) years. All results were compared with the results of 57 healthy person who were selected from both sexes (29 males and 28 female). Eight milliliters of venous blood were collected from control subjects and patients with renal failure by using disposable syringe of 10 ml before and after dialysis process.The blood analyses was conducted for evaluating the hematological parameters which are included (Hb, PCV, WBCs and PLT ) biochemical parameters which include (Blood Urea, Serum Creatinine, Total Protein and Calicum) electrolyte parameters which include sodium and potassium, measured concentration of (Erythropoietin and Aldosterone) hormone in patients with renal failure before and after dialysis and control groups and measure the effectiveness of phagocytic cells in patients with renal failure before dialysis by using Nitroblue Tetrazolium stain (NBT). The study revealed the following results : 1 - When comparing the results of parameters between before and after hemodialysis and peritoneal dialysis with healthy control show the following : a - Significant decrease (P < 0.01) in the levels of (Hb and PCV) while significant increase (P < 0.01) in PLT in renal failure patients before and after dialysis compared to healthy control and significant increase (P < 0.01) in the numbers of WBCs in male peritoneal dialysis patients compared to healthy control.b - Significant increase (P < 0.01) in urea, creatinine, sodium, potassium and in the aldosterone hormone concentration in renal failure patients before and after dialysis compared to healthy control.c - Significant decrease (P < 0.01) in the erythropoietin hormone concentration, total protein, calcium and phagocytic cells activity in renal failure patients compared to healthy control.2 - When comparing the results of parameters between before and after dialysis for each type of dialysis showing the following : - a - All hematological parameters and the concentration of hormones (Erythropoietin and Aldosterone) observe no significant differences between before and after dialysis.b - Significant decrease in the levels of urea, creatinine and there is a significant increase in the levels of total protein and calcium after dialysis comparing with before dialysis.c - Significant decrease in the levels of potassium in hemodialysis patients after dialysis comparing to before dialysis and there is a significant decrease in the levels of sodium and potassium after peritoneal dialysis comparing to before dialysis. 3 - When comparing the results of males and females hemodialysis with males and females peritoneal dialysis shows the following : a - Significant increases in numbers of WBCs before and after dialysis in the male and female peritoneal dialysis comparing with hemodialysis b - Significant decreases in the levels of urea and creatinine after dialysis in the male and female peritoneal dialysis comparing with hemodialysis.c - No significant difference in the levels of Hb, PCV, PLT, total protein, calcium, sodium, potassium, the phagocytic activity and the concentration of hormones (Erythropoietin and Aldosterone) before and after dialysis in the male and female hemodialysis comparing with peritoneal dialysis. We conclude that renal failure patients in Wasit Province suffer from severe anemia, high blood pressure, increase in the levels of urea and creatinine, disturbance in the levels of potassium, sodium and calcium with deficiency in the body's immunity.

المستخلص: اجريت الدراسة في كل من مزرعة العرهون التابعة لقسم وقاية النبات - كلية الزراعة ومختبرات قسم علوم الحياة - كلية التربية للعلوم الصرفة في جامعة تكريت خلال المدة 1/9/2013 - 10/6/2014 تضمنت دراستين الاولى تم فيها تقدير تاثير اضافات متنوعة من المدعمات الكاربو | The study was conducted in each of the Al - Mushroom farm in Department of plant protection, College of Agriculture and the laboratories of Biology Department - College of Education for Pure Science at the University of Tikrit for a duration of 1/9/2013 to June 2014. The first studies were included the adding of carbon, nitrogen and other additives at casing period on productivity, quality characteristics and chemical composition of Agaricus bisporus mushroom. The results showed significant increased (p<0.05) in total production and biological efficiency when adding carbon supplement at 1% of starch and became 26.41 kg/m2 and 88.03% respectively, also with nitrogen supplement at 1% from Erbil feed (EF) that’s became at 23.20 kg/m2 and 77.33% respectively, compared with the same value in control group which at 21.68 kg/m2 and 72.26% respectively. Also both treatments were recorded earlier in production at 15 and 16 days after casing compared with 18 days in a control, while the qualitative characterizes has been the treatment of 3% from methionine the highest content of total antioxidants and became at 1975 µg/g dry weight compared to the 1572 µg/g dry weight in the control treatment, and the highest protein content was became at 40.32% in treatment of 1% of LB compared with 22.36% of their content in the control treatment. The treatment of 1% of EF was recorder as higher content from mineral of calcium, magnesium and iron at 390, 2574, 50.74 µg/g dry weight compared to the content in the control group at 290, 1683 and 37.64 µg/g respectively, and the treatment of sodium selenite 5% was recordes a higher content of selenium at 5.00 µg/g compared to the control treatment which at 4.00 µg/g dry weight. The treatment of EF also recorded a higher copper content at 108.60 µg/g dry weight compared to the control treatment which at 37.00 µg/g. The other study was apply to assessment the effects of replacing casein at 5, 10 and 15% by the Agaricus bisporus product from the treatments with starch and multi - vitamin and EF on some growth and physiological parameters in female rats feding for 28 days. The results showed that the presence of mushroom in food has caused a significant decline in weight. The present of mushroom powder at 5% in rats feed lead to significant increasing in hemoglobin and total account of RBC resulting in 12.53 and 6.36× 106 cell/mm3, 13.13 and 7.06× 106 cell/mm3, 7.36× 106 cell/mm3 for starch, multivitamins and EF, respectively, compared to 12.25 and 6.8× 106 cell/mm3, respectively. As well as the significant increased in the total counts of white blood cells that were at 5.50, 5.20 and 5.00 x 103 cells/mm3, respectively, with the starch, and at 5.70, 5.40 and 5.20 x 103 cells/mm3, respectively, with multivitamins and at 5.90, 5.50 and 5.40 x 103 cells/mm3, respectively, for the EF group compared with the control group were at 5.15 x 103 cell/mm3. also was significant increased in differential WBCs as lymphocytes with increasing the replacing percentage for treatments above. Also due the replace of casein by mushroom on proportions referred to in the above change in blood biochemicals parameters which significant decreased in urea, total cholesterol, triglycerides and low density lipoproteins and increase the concentration of high density lipoproteins, as well as reduced the activity of enzymes Alanine amino transferase (AST), Aspartic amino transferase (ALT) and Alkaline phosphatase (ALP) with increasing the percentage of replacing. As for the effect of replacing the same proportions of the mushroom instead of casein on growth and physiological characteristics of female rats with experimental diabetes induced by Alloxan and fed for 17 days. The results showed that the development of diabetes trial led to a reduction in the rate of animal weights and an increase in the relative weight of internal organs such as the heart, liver, spleen, pancreas and kidneys of infected sugar group, and became at 0.46, 4.39, 0.60, 0.46 and 1.19 g/100 g respectively when compared with the control animals, at 4.07, 0.42, 0.39, 0.23 and 1.04 g/100 g, respectively. And decreased of red blood cells that were at 5.93 x 106 cells/mm3, respectively, for the group affected by diabetes, while at 7.36 x 106 cells/mm3 respectively the healthy control group. And decreased WBCs in the infected animals with diabetes trial and became at 4.83 x 106 cells/mm3 compared with the healthy control group which at 7.03 x 103 cells/mm3. Also there was caused in significant increased in glucose concentration, which was on the first, 7th, 14th, and 17th days at 428, 405, 431.60 and 432.20 mg/100 ml respectively, in comparison with a control without diabetis that was at 123.33, 124.66, 126.33 and 125.33 mg/100 ml, respectively. Further to increased concentrations of urea, cholesterol, triglycerides and low density lipoproteins and a decrease in the values of high density lipoproteins also, increased the values of enzymes activity of each Alanine amino transferase(ALT), Aspartic amino transferase (AST) and Alkaline phosphatase (ALP) compared with the non - diabetic infected control group. That feeding female rats of experimental diabetes on the replacement rates of the mushroom instead of casein in their diet has led to the significant decline of the weight and relative weight of internal organs such as the heart, liver, spleen, pancreas and kidneys compared with animals infected with the induced diabetes with increasing rates of substitution. The results also showed that increased in total counts of red and white blood cells that was at 6.40 x 106 cell/mm3 and 5.00 x 103 cell/mm3 respectively when replacing 5% casein from mushroom compared to the infected control group were at 5.93 x 106 cell/mm3 and 4.83 x 103 cell/mm3 respectively. The substitution of casein with 5, 10 and 15% from mushroom was caused to significantly lower of glucose values to became 273.40, 251.60 and 302 mg/100 ml compared with control group infected which at 432.20 mg/100 ml. Also, because of the found of mushroom in the food was caused a changed in the biochemical blood, which significantly reduced the concentration of urea, total cholesterol, triglycerides, LDL and increase the concentration of HDL. As well as significantly reduced the enzymes (AST), (ALT) and (ALP) activity with the replacement rate increase compared with values in the animals infected with diabetes induced by Alloxan. The results concluded that the possibilty of use starch and EF at 1% for the commercial mushroom production. Mushroom also can be used as a food for lowering blood glucose, cholesterol, triglyseride, LDL and liver enzymes with increase in HDL for the people suffered from diabetes, obesity and heart diseases.

The proportion of infected women with cutaneous leishmaniasis ulcers was higher 56.522% than males 43.47%, the age group ten years and less was more group that being infected with rate 47.83% while the age group that rang from 71 to 80 was the less categories being infected in percentage 0.87% with a significant differences in the level of improbability less than 0.05. The presence of multiple ulcers was high 71.304% than single ulcers 28.696%. The presence of ulcers that length 1 cm and less (64%) more than other with more than 1 cm (36%) with statistically significant. The cutaneous ulcers were distributed on different areas of the body, the injuries on face was more 36.242% with anumber of 54 cases followed by upper limbs in rate 33.557% with anumber of 36 cases, the sore shoulder came latter with apercentage 1.342% in a significant differences at the level of improbability less than 0.05. The percentage incidence of cutaneous leishmaniasis was rise in kids and students in rats 33.043%, 39.130% respectively in a comparison with earners, housewives and of officers their percentages were 24.349% and 3.478% consecutively in statistically differences at 0.05 probability. The diagnosis of cutaneous leishmaniasis infections was done depending on clinical diagnosis based on the characteristics of the morphological and pathological ulcers, culture methods, impression smears and histopathological diagnosis. Clinical diagnosis for the cutaneous ulcer was recorded 100% percentage in comparison with culture method 10.435% versus 74.782%. percentage to positive smears, while the result of positive histopathological diagnosis was 88.571% on vision of promastigote of Leishmania parasite on semisolid medium while a adoption of existence amastigote from as appositive result of smears and histopathological method of the tissue biopsies taken from ulcer. The histopathological method was high efficiency supported clinical diagnosis when compared to other methods this rise in the diagnosis ratio has been demonstrated in significant differences in statistical probability less than 0.05.A study of amain impacts of histopathological changes in cutaneous ulcers on the infected skin layers at the level of light microscopy was also conducted. These pathological effects were in epidermis of skin including hyperkeratosis, pseudoepitheliomatous epidermal changes, ulcers and emergence of a dark colour, thickening in this layer accompanied suppurations and desquamation of chronic cases. As for the dermis layer, the inflammatory cells were infiltrate include plasma cells, macrophages, lymphocytes and eoisophils, disturbance in the order of layers especially in acute ulcers was taken, while the pathological effects were more in chronic ulcers as observed granulomatous inflammation and necrosis. The amastigote from were presence inside and outside the phagocytic cells.Aswell as some immunological changes that associated with the infection were studied in patients therapists by Pentostame (Sodium Stubogluconate) medication and uninfected control group by measuring the levelsof some cytokines IFN - ?, TNF - ?, IL - 12, IL - 17A and the chemokine MCP - 1. The level of IFN - ? was elevated in serum of cutaneous leishmaniasis patients and reached to 54.118±1.740 pg/ml, then the level was decreased during therapy and recorded 34.421±0.984 pg/ml after 1 - 3 dose a then dropped more after 4doses and more 22.489±0.795 pg/ml compared to uninfected control group 5.092±0.805 pg/ml. As well as the case of TNF - ? which rose their concentration in serum of CL patients and reached to 98.145±2.925 pg/ml, then decrease after treatment 71.507±2.901 pg /ml, 48.381±2.379 pg/ml after 1 - 3dose and more of treatment respectively, while the mean of TNF - ? in control group was 13.173±1.388 pg/ml.An increase in the level of IL - 12 was observed in the group of CL patients 845.598±16.273 pg/ml then the level was dropped during treatment and recorded 619.164±20.209 pg/ml, 495.578±27.038 pg/ml respectively but in control the concentration was 160.222±11.761 pg/ml. IL - 17A level was elevated in CL patients 227.268±5.027 pg/ml and decreased during therapy reach to 170.512±5.481, 126.443 ± 5.565 pg/ml after 1 - 3 doses and four doses and more respectively. The concentration of MCP - 1 chemokine was increased in CL patients 111.0397± 6.985 pg/ml then dropped during treatment 71.084± 2.636 pg/ml after 1 - 3 doses then dropped more 49.543± 2.167 pg /ml after four doses and more while they were in control 12.268 ± 1.609 pg/ml. The results of statistical analysis showed significant differences between these cytokines and their groups at the level of probability less than 0.05.

المستخلص: The study includes distribution of the Cutaneous Leishmania in some governorates in Iraq. Specimens are included cases of outpatients in hospitals like : Al - Karamah, Al - Sadir Teaching Hospital in Baghdad, Al - Hilla Teaching Hospital, Al - Hussein Teaching Hospital and Ein Altamer General Hospitals in Kerbala, Al - Sadir Teaching Hospital in Al - Najaf, Al - Karamah and Al - Zahraa Teaching Hospitals in Wasit, Al - Diwanyia General Hospital. Al - Hussein General Hospital in Al - Nasiriya, Al - Smawa General Hospital, Al - Sadir Teaching Hospital and Al - Qurna General Hospital in Al - Basrah during October 1122 to march 1121 Cutaneous Leishmania is consider a major problem that faces the patients because it causes deformities in the infection region. The study includes 330 cases of skin ulcer in which 225 of them were microscopically positive. Parasitic growth was done using two types of cultural media NNN and RPMI - 1640.The results have shown a considerable difference between male and female in which male was significantly exceeding 131) %22.11 (and female was 94) %72.44 (and 139) %72.44 (of outpatients from rural areas increased in numbers from outpatients of urban areas, and only) %12.11(from urban areas.The number of ulcerations in body has exceeded infection, that means more than one ulceration in male 83 (85%) and for female 41 (62%), and concerning infection in three or four ulceration, it is approximately equal and normally distributed on face areas 99 and a percentage of (44%) then lower arms are 92 and a percentage of (40.80%) and the upper parts are 33 and a percentage of (14.66%). Also, one infection was recorded on The study shows that 46 patients in a percentage of (%20.44) having a dry infection; whereas 179 patients (%79.55) having the wet type.For accurate diagnosis of Leishmaniaa species distributed in Iraq, PCR Was used technique and diagnosed two types of Leishmania parasite that causes the illness. A band in a length of 560 bp in 186 samples related to Leishmania major and the band sample was 750 bp related to 39 Leishmania tropica.Through studying the samples in Kerbala City, the number infected samples were 125 for the years of 2010 - 2011 the actuality is (73) infection and (52) infection from 2011 - 2012 in a ratio of (58.4 % and % 72.7 accordingly) in different inhibited areas in the governorate in which (51)) %71.2 (was in Ein Al - Tamir Suburb, and 29 cases of) %11.1 (in Al - Husseinya Suburb, as well as 17 cases of (13.6%) in Al - Hur Suburb, 16 cases) %21.2 (in the south quarters and 7 cases of (5.6%) in the north quarters and only 5 cases of (4%) in the city center.The molecular diagnosis in Polymerase Chain Reaction for Kerbala governorate samples have shown 31) %17.2 (of L.tropica, 22) %24.7(of them were male and 9 of) %4.1 (of them were female. L. major was 94 of) %42.1 (in which 55 of) %77 (were in male and 39 of) %12.1 (were in female.The immunological study for the patients serums with L. major by ELISA technique has significantly shown raised values of IgG and IgM during infection in comparison with the control group, then it declines slowly after treatment in which IgG was in ratio (1811.1 ± 523.1 mg/dl), and IgM was in ratio (166.7 ±23.6 mg/dl). Also, in L. tropica - IgG was in ratio (1722.1 ± 524.0mg/dl) and IgM was in ratio (25.3±182.9mg/dl) in comparison with control specimens, and then the ratios have declined after treatment dosages with Pentostam drug.The cellular dynamics values have shown an abstract increase in which interferon - gamma (IFN - ?) in infected patients with cutaneous L. major were (221.1±2.2mg/dl) which declined after treatment abstractly to (7.12±1.1mg/dl) as well as for L tropica (22.1±7.2mg/dl) which shows no significant abstract difference after treatment with control.An increase appears in cytokine IL - 10 that reached in L.major (122.1±8.2mg/dl) and after treatment was (8.11±2.2mg/dl) and in L. tropica was (222.1±2.2mg/dl) with no significant abstract difference after treatment with control specimen.As a simple attempt to find a vaccine for Leishmania disease a Lipophosphoglycan was isolated and purified as known factor for promastigot stage. The vaccine injected for two groups of Bulb mice in a concentration of purified vaccine (L.majorand Ltropica) to study the immunological response by detecting the Lymphocyte Transformation assay, the Delayed Type Hypersensitivity test and the PhagocytosisIndex.In lymphocyte transformation the ratio of L. tropica was % 7.2 and for L. major was % 21.7 and there is significant difference by P? 0.05 in comparison with control specimen in which its ratio was %7.4, and for Delayed Hypersensitivity test study the average foot thickness injected with vaccine and the other foot which injected with phenol - saline solution - only (1.11 ± 2.12ml) for the first group and (1.21 ± 2.72) for the second group, and for the control group it has registered (1.77± 1.15 ml) with a considerable difference of P? 0.05. By calculating the ratio of Phagocytosis Index cells, it was 17% and 27.6% for the first and second groups while for the control group it has been reaching 9.10%. Therefore, we can get advantage from these values as indicators for the rule of vaccine in the immunological response and triggering of vaccine idea for this disease.

The animals were randomly distributed into four equal groups , ( 10 rats per each group / cage) as follow : - Control group : The rats were given only basal diet and deionized drinking water - - First treatment group ( T1) : The rats were given basal diet and deionized drinking water that contain 1000 ppm lead acetate for 30 days. - Second treatment group ( T2 ) : The rats were administrated basal diet and deionized drinking water that contained 1000 ppm of lead acetate and received orally ( by gavag ) fermented mare's milk at a dose ( 10ml / kg b.w / day ) for 30 days. - Third treatment group (T3) : The rats were given basal diet and deionized drinking water that contained 1000 ppm of lead acetate and received orally ( by gavag ) EDTA at a dose ( 50 mg/ kg b.w / day ) for 30 days. At the end of the experiment all the animals were fasted for ( 12 hours ) and then killed animals from each treatment group blood samples were collected from the heart to measures some blood parameters such RBC , Hb and PCV and biochemical parameters such as liver function parameters ( total protein and activity of some enzymes such as ALT , AST , ALP and LDH ) , kidney function parameters such as Urea and Creatinine concentration and oxidative stress parameters such as GSH , SOD , MDA ). In addition to that study the histopathological changes of liver and kidney tissues were studied The results of the present study can be summarized as follow : - 1 - Blood parameters : The results of the statistical analysis showed that there was a significant ( p < 0.05 ) decrease in the mean values of RBC , Hb , and PCV in a group treated with lead acetate only ( T1 ) as compared to other experimental groups. while groups treated with EDTA and fermented mares milk showed a significant ( p < 0.05 ) improvement in blood parameters. 2 - Biochemical parameters : A - Liver function parameters : The result revealed that there was a significant ( p < 0.05 )effect of lead acetate on level of total protein where caused a decrease in total protein concentration and increase the in activity of ALT , AST , ALP , and LDH as compared to other experimental groups. Yet treatment with fermented mare's milk ( T2 ) resulted in an increase in the total protein concentration and a decrease in the activity ALT , AST , ALP AND LDH. Also treatment with EDTA ( T3 ) caused a similar results to ( T2 ).

المستخلص: اجريت الدراسة الحالية خلال الفترة من تشرين الثاني 2014 الى نيسان 2015، جمعت العينات المرضية من النساء التي تعاني من حالات الاجهاض وولادة مبكرة والاطفال المصابين بالتهاب السحايا من مستشفى الولادة والاطفال التعليمي وقد جمعت العينات تحت اشراف طبي متخصص وكان | This study was carried out during the period from November 2014 to April 2015, whereas samples were collected from women that suffered of abortion and infected children in the maternal and children hospital in Al - Qadissiya province , so the samples were collected under supervising of a specialist medicine , the number of taken samples of the women is 65 samples , while the number of taken samples of children is 32 samples , so the samples that belong to animals have included a gall bladder samples were collected from Al - Diwaniya slaughterhouse were 100 samples of sheep and 100 samples of cows. in addition to collect 200 samples of milk as 100 samples for each sheep and cows from different rural zones in al - Qadissiya province. L.monocytogenes was isolated by using oxford listeria selective agar for listeria , so the special stimulator for growth of the bacteria was added to it in order to determine the type of bacteria , also it diagnosed an isolates for L.monocytogenes by using the microscopically examination and biochemical tests , furthermore the germ isolates was planted on blood agar for diagnosing the blood analysis type : ? - heamolysis as affirmative checking for the isolates. also PCR technique used for affirming the diagnosing of L. monocytogenes by using the initiator for the blood analysis gene (hly) , whereas all the L. monocytogenes isolates' gave a positive result in inspection , so this technique is used too in the detection about the serous types for L.monocytogenes isolates by the molecular diagnosing for the fierce genes of the germ and these are (D1,D2,Glt,FlaA and MAMA gene ). The results of the research showed that isolating and diagnosing percentage of the Listeria monocytogenes is about 9.27%, whereas the isolation percentage in women infected in abortion is 4.61%, while the percentage of listeria germ isolation was higher in the children that infected in meningitis whereas it was 18.75% of the total amount of the samples.As for the percentage of the isolating in sheep it was 4% and 7% for milk and gall bladder respectively. In the cows the isolation percentage of the germ from milk and gall bladder was 2% and 3% respectively. So the the results of isolating for listeria germ during the study period in human and animals were disparate , whereas the highest percentage of isolation for the germ in human were scored in January and February months of the year whereas it scored 20% and 16% respectively.As for sheep the percentage of isolation was higher in December and January months whereas it is 6.25% and 10% respectively , while in the cows the percentage was higher in January and February months where it is 4.2% and 7.4% respectively. Regarding The results of detection about the genes of the serous types for the isolates of L.monocytogenes by using PCR technique 14 isolates of the samples showed a positive result when they react with the initiator for gene (D1)in percentage about 56%, so this isolates showed a positive result when they react with the initiator for gene (Glt) as amount of 5 isolates and they classified to be belong to the serous types (1/2B or 3B), while 9 isolates gave a negative result in the inspection , whereas these isolates were tested with the initiator for gene (MAMA), 5 isolates showed a positive result in this reaction with this gene and they classified to be belong to the serous types (4c or 4a), while 4 isolates gave a negative result as they classified to be belong to the serous types (4b or 4d or 4c).As for the isolates' that gave a negative result with the initiator of gene (D1)there are 11 isolates all these isolates gave a positive result when they inspected with the initiator of gene (D2) in a percentage about 44%, so when these isolates inspected with the initiator for gene (FLaA) then 6 isolates of them gave a positive result in the inspection and classified as they belong to (1/2a or 3a), while 5 isolates of them gave a negative result in the inspection and classified as they belong to (1/2c or 3c). As for the serous types that have not diagnosed in the germ isolates of the human there are(1/2a or 3c), while in the germ isolates of the sheep the serous types (4a or 4c) have not been diagnosed , then the serous types (1/2b or 3b) have not been scored in the cows. The present study concluded that the percentage of infection in L.monocytogenes was high in human in al - Qadissiya province , in which that refer to the risks of the diseases and health problems spread that could be caused by L.monocytogenes , also the results included isolating the germ from milk and gall bladder samples for sheep and cows that could be a source to carry the infection to the human by contaminating the meat, milk and its derivatives'. whereas the isolation percentage of the germ was higher in the cold months of the year in human and animals, so the highest isolation percentage of the serous types for the L.monocytogenes in human and cows were (4a , 4c) , while in sheep the serous types were (1/3c,3c).

Psoriatic arthritis is most commonly a seronegative oligoarthritis found in patients with psoriasis and therefore occurs more commonly in patients with tissue type HLA - B27. The clinical findings for Tempromandibular Psoriatic arthritis are pain, tenderness, limitation of movement , joint stiffness, clicking as the jaw is opened or closed, difficulty in opening the mouth, locking of the jaw,and crepitations. These findings are essentially the same as for Tempromandibular disorders.• Objective of the study : • To determine the extent of tempromandibular joint involvement in patients with psoriatic arthritis.• To correlate between clinical findings and radiographic finding.Materials and method : In this study 98 patients were selected ,50 male and 48 female, their age ranged between(18 - 68)years. They were collected at Al - yarmook teaching hospital/department of dermatology during the period from ( NOV 2014 - May 2015).They were diagnosed as having psoriatic arthritis by a dermatologist according to (Moll and Wright diagnostic criteria 1973).These patients were sent to rheumatoid factor test RF to exclude the presence of rheumatoid arthritic disease, then the patients were exposed to CT scanning for the Tempromandibular joint in Al - Yarmook teaching hospital for screening the involvement of TMJ with psoriatic arthritis by the presence of any radiographic changes such as erosion, flattening,osteophyte and sclerosis in the condylar head.Results : The result of the study showed that the mean age of psoriatic arthritic patients in TMJ was (44.2) years, and the female percentage was (48.4%) and the male was (51.6%). Psoriatic arthritis in TMJ showed high significance in the unilateral side symptoms (100%) it was significant in patients with positive family history (54.8%), and non significant in the right/left ratio (41.9%). Oligo type was found in twenty six patients (83.9%) with significant p - value. Clinically, all symptoms including clicking, tenderness and tempromadibular joint pain were highly significant, limitation showed (54.8%), TMJ pain showed (64.5%) and tenderness showed (54.8%).Radiologically : CT scan showed sensitivity for erosion in TMJ (54.8%), for osteophyte (32.3%), for condylar flattening (16.1%) and for sclerosis (9.7%) while specificity for all were (100%). Association between clinical symptoms and radiological changes showed non significant correlation. Conclusions : Psoriatic arthritis of TMJ has been found oftenly unilateral (oligo type). Female/ male ratio is about 1 : 1. nearly 50% of patients were having limitation in mouth opening. Most of the patients were having positive family history.The development of psoriatic arthritis in TMJ is related to the duration of the disease. Plaque psoriasis is the most associated type with the psoriatic arthritis in TMJ. Most of patients with psoriatic arthritis show psoriatic nail changes. The most radiographic findings found in patients with psoritic arthritis was erosion in the condylar head. There is association between clinical and radiologic findings for psoriatic arthritis in TMJ.

Recently, in endodontic practice, the nickel - titanium instruments are used commonly for the preparation of the root canal space. Nickel - titanium instruments are much more flexible than stainless steel files and have superior cutting efficiency. Super - elasticity of nickel - titanium rotary instruments allows the clinicians to produce the desirable tapered root canal form with a reduced tendency to canal transportation and instrument fracture. The target of this study was to measure and compare the canal transportation and centering ability of iRaCe and ProTaper NEXT nickel titanium instruments with ProTaper Universal instruments in simulated curved canals at different levels and compare canal transportation and centering ability among different levels for each tested instrument.Sixty simulated curved canals of 40°curvature were randomly divided into three groups of twenty canals each; the first group (group A) was prepared with iRaCe instruments, the second group (group B) was prepared with ProTaper NEXT instruments and the third group (group C) was prepared with ProTaper Universal instruments. The canals were prepared to an apical size 30 by crown - down instrumentation technique. Removal of material was measured at five different levels : at the canal orifice (O), half way to the orifice in the straight sections (HO); the beginning of the curve (BC); the crest of the curve (AC); the end point (EP). Pre - and post - operative photos of the simulated canals were taken in a standardized technique at magnification of 40X. An assessment of canals shape has been determined using Photoshop CC 2014 and AutoCAD 2014 software program. The data of canal transportation as well as centering ratio were analyzed statistically using Shapiro - Wilk, ANOVA and LSD tests.Within the limitation of this study, it is shown that canals preparation with the three designs of NiTi instruments produced canal transportation. However, the iRaCe instruments showed a significantly less canal transportation and a significantly better centering ability than both ProTaper NEXT and ProTaper Universal instruments at all levels of measurements, followed by ProTaper NEXT instruments that showed a significantly less canal transportation and significantly better centering ability at all levels when compared with ProTaper Universal, while the ProTaper Universal instruments showed the highest values of canal transportation and the worst ability to stay centered in the canals at all levels. Considering the direction of canal transportation, the iRaCe instruments showed minimal transportation towards inner aspect of canal at coronal and at the apex of curve and towards outer aspect of canal at middle, beginning of curve and at the end point of the preparation, while ProTaper NEXT instruments were showed transportation usually towards the inner aspect of the canal at middle part of the canal and towards the outer aspect at coronal, beginning of curve, apex of curve and at the endpoint of the preparation, while ProTaper Universal files were usually towards the inner aspect at middle part of the canal and towards the outer aspect at coronal, beginning of curve, apex of curve and at the endpoint of the preparation.

The etiopathology of the temporomandibular joints is related to muscles, teeth arches, and periodontium. Their main causes involve both pathophysiological and psychosocial factors. In the literature, a significant impact of the psychoemotional factor is reported, comparable to the impact of other factors concerning physical health such as systemic diseases, malocclusions, loss of teeth, and traumas. Stress, fatigue, anxiety, depression, sleep disorders, and a fast pace of life affect negatively the human psyche.Aim of study : The aim of the study was to assess the prevalence of temporomandibular disorders (TMD) and oral parafunctions, as well as their correlation with psychoemotional factors among dental students by using diagnostic criteria (DC/TMD).Subjects, materials and methods : the sample’s size of 407 students (169 males and 238 females) of dental college (100 fifth stage , 102 fourth stage ,99 third stage and 106 second stage ). Firstly students subjected for stress questionnaire (perceived stress scale - 10) , secondly they subjected to different clinical and questionnaire measures according to diagnostic criteria of temporomandibular disorders DC/TMD (axis1) which have standerized series of diagnostic tests based on clinical signs and symptoms , finally the dental students subjected for oral parafunctions questionnaire using oral behavior checklist.Results : the results obtained from this study showed that the prevalence of TMDs was significantly greater among students with oral parafunctions. We also observed that the prevalence of TMDs according to DC/TMD was higher among students with headache.In this study, the prevalence of psycho - emotional stress , TMD according to DC/TMD and oral parafunctions were higher in females than males and in fifth stage greater than other stages.Conclusion : • the prevalence of TMDs according to DC/TMD were significantly higher among females than males.• Oral parafunctions ( bruxism , cheek/lips biting , objects biting and nail biting ) showed greater prevalence in fifth stages than others and higher in females than males • In all stages females showed greater prevalence of psycho - emotional stress than males and among students of fifth stage the prevalence of psycho - emotional stress was higher than other stages.

All teeth had mature apices, selected carefully according to specific criteria. The roots were instrumented using crown down technique with rotary Protaper universal system, instrumentation were done with 5ml of 2.5% sodium hypochlorite used as irrigation between files, 17% buffered solution of EDTA was used as final irrigant followed by 2.5% sodium hypochlorite then 10ml distilled water to remove any remnant of irrigant. Roots were randomly divided into three groups according to the filling materials used ( twenty roots for each group) : Group (1) : MTA Plus ( 4mm thickness) using as apical third filling. Group (2) : Biodentine (4mm thickness) using as apical third filling.Group (3) : Bioceramic root repair material (4mm thickness) using as apical third filling.Easy and Quick (E&Q) obturation system were used to complete obturation of roots. After incubation period at 37 °C for three days. Ten roots from each group were used for push - out test, after root were embedded in clear acrylic resin, sectioned at apical level in 2mm and 4mm from root apex to provide slice 2mm in thickness. The bond strength was measured using computerized universal testing machine, each section fixed in the machine so that the load applied from apical to coronal direction at 0.5mm/min speed and the computer drew curve to show the higher bond force before dislodgment of the filling material. These force were divided by surface area to obtain the bond strength in MPa.After debonding each sample was examined under Stereomicroscope and the type of failure mode was recorded. The result showed non significant different between Biodentine group and MTA Plus group. Biodentine group showed a very high significant difference with Bioceramic material group. Also high significant difference between MTA Plus group and Bioceramic material group. The Biodentine group showed highest mean of bond strength in comparison to other test group.Ten roots remain from each group used for apical microleakage study. The roots submerged in 2% methylene blue for three days. The roots were cleared and the degree of linear dye penetration was measured in millimeter by stereomicroscope under 40 X magnification with calibrated scale ocular grid. The result showed the Biodentine group lowest mean of microleakage than other group while Bioceramic material group showed high mean of microleakage than other groups. There are no significant difference among groups. There is positive correlation between push - out bond strength and an apical dye penetration in microleakage for each group of material.
