Abstract: نظرا لما تتمتع به مركبات الازو من تطبيقات مهمة في كل من المجالين الاكاديمي والتطبيقي فقد تمحورت دراستنا على تحضير ستة ليكاندات ازو جديدة مشتقة من المركب 5,4 - ثنائي فنيل اميدازول ودراسة السلوك التناسقي لكل منها مع ستة ايونات فلزية هي Co(II) , Ni(II) , C | Azo compounds have important applications in both of academic and applied fields, Accordingly, our study based on the synthesis of azo compounds derived from 4,5 - diphenyl imidazole and characterization of these azo compounds with their metal complexese containing Co(II) , Ni(II) , Cu(II) , Zn(II), Cd(II) and Hg(II) ions. Mass Spectra of ligands and their complexes were supported their molecular formula, while H1NMR spectra of ligands agreed well with the suggested structures , The C.H.N. and Atomic absorption analysis showed a good agreement with the calculated values , The purity of ligands and their complexes were examined by TLC and the values of Rf were values measured.Electronic spectra of complexes showed a bathochromic shift comparing to ligands spectra as a result of the coordination between the metal ions and ligands. The concentrations that obeyed Beer - Lambert Law of the complexes were determined from calibration curves , Mole Ratio Method indicate a ratio (1 : 2) (Metal : ligand) for the complexes of (DPEPI) and (DPDED) while other complexes with other ligands show a ratio (1 : 1) (Metal : ligand).Satiability Constants of the complexes were calculated and found that the Stability constants of complexes of the first ligand (DPEPI) were ( 2.955×10 12) >(2.294× 1011 ) <(1.121×10 12 ) < (1.108 ×1011 ) varied in the arrangement as Co(II)< Ni(II) < Cu(II)> Zn(II) which agree with Irving - Williams Series. This arrangement was applied on the complexes of the other ligands. The Conductivity measurements of complexes showed non ionic character. Apparently the magnetic susceptibility values agree with their values of the octahedral high spin complexes for Co(II)) while the complexes of Zn(II), Cd(II), and Hg(II) were diamagnetic. IR Spectra of complexes showed obvious changes of the frequencies of ? (N=N) of azo group and ?(C=N) of heterocyclic imidazole ring as result of coordination with metal ions, While the frequencies of ?(C=N) of azomethine group did not show any significant change for complexes comparing to the ligands spectra ,New bands were appeared in the region (400 - 500) cm - 1 in the spectra of complexes that due to frequencies of ?(M - N) because of coordination process. From the previous results the purposed structures of the complexes can be summarized as shown in the following : Proposal structure of (DPEPI) Complexes Proposal structure of (DIDHP), (DIDMP),

H.europaeum L., H.lasiocarpium Fisch., H.noeanum Boiss., H.ramosissi | The current research study is a comparative morphological, anatomical, chemical, genetical of the genus Heliotropium in mid and north of Iraq between eight species belonging to the genus of the family Boraginaceae, and the study included some morphological characteristic of the roots, stems, leaves, flowers (calyx, corolla, stamens, pistils), inflorescence, fruits and pollen grain shows that there are clear differences between the species under study. The study included aspects of anatomy and the differences included the qualities of epidermis leaf and stem and stomata as well as study transverse sections of roots, stems, leaves and petiole and peduncle, fruits, Nutlets and seeds, also studied the system of Venation in the leaf where he studied the type of venation as well as study the direction of midrib, thickness, branching as well as the study of secondary veins, Arrangement, Aerioles and Veinlets that showed clear differences between species.The study showed that pollen grains in the species are Tricolporate in all species except H.bacciferum it contains four grooves and pollen grains of contain Psaudotricolporate found in all species except H.lasiocarpium was completely absent of false grooves have distinguished this species by this character, showed the study of pollen grain Psaudotetracolporate in species H.bacciferum only and did not appear in the rest of the species. the study noted that there are variations evident in the two axes equatorial and polar as well as in the length of the groove, width, the rate of the thickness of the wall of pollen grain, the rate of diameter germination aperture in all species. The study showed clear difference between species in dimensions of upper and lower epidermis leaf, as well as a study stomata index on the surfaces of upper and lower leaves where show that all species were the lower surface more than the upper surface in density of stomata and Trichomes were studied in all parts of plants under study it was observed that there is variation in the distribution of hair and their locations as well as the lengths of hairs and thickness of the walls and shape of apex and base. Studied species in pathway of photosynthesis showed that two species are C4 plants H.noeanum, H.suaveolens either species H.bacciferum, H.ramosissimum, H.lasiocarpium was belong of intermediate C3 - C4 species while the rest were from C3 plants after analysis qualities and similarities of these qualities were very important to isolate the species from each other because present of bundle sheath, thickness of leave in cross section, thickness of cuticle, thickness of chlorenchyma and collenchymas tissues, frequency of stomata and it distribution, the number of aerioles and veinlets density and size. Has also been studying the chemical content of alkaloids and found that there are six alkaloids isolated for the first time from inflorescences for plants belonging to the genus Heliotropium were isolated using the technique liquid chromatography for identified six alkaloids compounds (indicine and supinine, indicine - N - oxide, heleurine, heliotrine and lindelofidine), which included the study of compounds Alkaliods type, concentration and percentage and the pyrrolizidine alkaloids that have a biological importance of cure tumors and cancers. The study showed high percentage of heliotrine in four species of Heliotropium H.bacciferum, H.ramosissimum, H.europaeum, H.noeanum were (48%, 54%, 51%, 54%) while heleurine was high percentage in two species H.suaveolens, H.supinum were (33%, 56%), while the study showed lower percentage of indicine - N - oxide in three species H.ramosissimum, H.noeanum, H.supinum were (2%, 4%, 1%). The current research identified for the first time on the content of the Glycosides from inflorescences in eight species of Heliotropium from mid and north of Iraq. These species are H.bacciferum, H.ellipticum H.europaeum, H.lasiocarpium, H.noeanum, H.ramosissimum, H.suaveolens, H.supinum by using the liquid phase chromatography diagnosis of six compounds (heliotrope, isopyrrolidine, isorhamnetin, naringenin, quercetein, triterpene) results showed that plant species studied vary their content of these compounds, with absent of naringenin in the species H.noeanum while absent of triterpene in species H.ellipticum, H.europaeum, H.supinum. They also showed the studied differences in concentrations glycosides and percentage of species as shown H.europaeum, H.lasiocarpium, H.noeanum, H.ramosissimum, H.supinum, H.suaveolens lower concentrations (12 - 37 mg / ml) and percentages (1 - 9%) for quercetein compared to the rest of the species studied and the species H.europaeum, H.lasiocarpium, H.noeanum, , H.supinum, H.suaveolens were higher concentrations (99 - 442 mg / ml) and percentages (26 - 51 %) for heliotrope compared to other species. These results indicate the possibility of the adoption of the content glycosides for inflorescence criterion for the separation between species as well as use for medical purposes, especially pyrolizidine and isopyrrolidine important in the treatment of tumors and cancer. Studied the genetic variation through the study of random variation indicators RAPD for eight species of the genus Heliotropium, and using 14 primer showed variation between the species under study and were divided into two groups are : 1. Group A : Included only two species H.bacciferum, H.ramosissimum where the genetic distance between these two species (0.249) where the two species are similar in genetic traits and genetic content in the absence of many bands of the primers and appear in the other. 2. Group B : Included six species of the genus Heliotropium under study and was less genetic distance between H.ellipticum, H.europaeum where (0.105) and this is a great similarity in appearance bands between the two species in some of primers, then the following two species were also two other, where he was the closest genetic distance between the two species H.lasiocarpium, H.noeanum where (0.153) and was very close two species of H.ellipticum, H.europaeum were was (0.125). The data were analyzed and characteristics after into the program (NTSYSpc) to study morphological and anatomical, chemical, genetic and find a genetic distance inter - species on the basis of similarity So was isolated species to groups and based on a large number of morphological characteristics and anatomical, chemical, genetic possible distinguish species from each other and show the variation at the level of species belonging to the genus Heliotropium.

Abstract: نفذت هذه الدراسة في كلية الزراعة/ جامعة القادسية خلال المدة من 10/4/2011 حتى 15/10/2011. الهدف منها دراسة الاستجابة لضربين من الباميا (الحسيناوية والبتيرة) لطريقتي اضافة حامض الدبال ومستحضر الزولفاست (الرش الورقي ومع ماء الري) وبتركيزين لكل منهما (الموصى | This study was conducted in Agriculture College, AL - Qadisiya University during the period of 10/4/2011 till 15/10/2011. The aim of the study was studying response of two okra varieties (Al - Husenawyia and Al - Pteira) humic acid and zolfast application methods (foliar and addition to irrigation water) and this concentration (recommended and doubled) on growth and productivity as well as leaf mineral and fruit medicinal active constituents.The humic acid and zolfast formulas were added by the use of hand sprayer or with irrigation water with the recommended and doubled concentrations for humic acid and zolfast as foliar spraying were 1 ml.L - 1 and 2 ml.L - 1 if doubled respectively while when used with irrigation water 4.8 ml.L - 1 and 9.6 ml.L - 1 if double for humic acid 7.2 and 14.4 ml.L - 1 for zolfast if doubled.The design of the experiment was Randomized complete blocks in a factorial arrangement (2×2×5) in three replications. The RLSD at 0.05 was used as a method to compare means separation treatment effect was evident. The results showed : 1 - Al - Husenawyia variety was superior in total leaf area, vegetative fresh and dry weights, root fresh and dry weights, P% and content addition to specific leaf weight, relative growth rate, fruit length, number of fruit/plant, fruits yield compared to Al - Pteira. Percentage of protein, carbohydrates, total soluble solids, caprylic, lauric saturated fatty acids and all the unsaturated fatty acids. Mucilage, folic acid and oil refractive index were also higher with Al - Husenawyia compared to Al - Pteira had higher stem diameter, fruit fresh and dry weight, K%, boron content and percentage of saturated fatty acids (Myristic, Palmatic, Stearic, Arachidic and Behinic). Ca% was the same for both cultivars.2 - Foliar application method of humic acid and zolfast showed beneficial effect on and all parameters studies except root fresh and dry weight and percentage of saturated fatty acids increased with irrigation water (except Lauric acid which was increased with foliar application). Methods of application did not affect stem diameter, Ca% in leaves and fruit total soluble solids.3 - Although the double recommended concentrations of humic acid and Zolfast reduced saturated fatty acids significantly their recommended concentration lowered saturated fatty acids (Caprylic, Myristic, Palmatic, Stearic, Arachidic and Behinic) compared to control treatment. Percentage of fiber was lower with the use of zolfast compared to humic acid and control. While K% was lowered when zolfast used in the double recommended concentration. No significant difference were found between the recommended concentrations of humic acid or zolfast in stem diameter, total leaf area, relative growth rate, vegetative dry weight, root dry weight, P%, Ca%, boron content, fruit length, number of fruit/ plant, fruit dry weight, mucilage, carbohydrates%, folic acid, oil%, percentage of saturated fatty acids (Caprylic, Myristic, Palmatic and Arachidic) and unsaturated fatty acids (Oleic and Linoleic) and the percentage of unsaturated fatty acids/saturated.4 - The interaction between cultivars and methods of application revealed that foliar application of both humic acid and zolfast reduced saturated fatty acid (Caprylic, Myristic, Palmatic, Stearic and Arachidic) significantly of both cultivars, compared to their addition to irrigation.5 - The interaction between cultivars and substances of application (humic acid and zolfast concentrations revealed that both cultivars had different response in some traits of studied to applied concentrations of humic and zolfast. Al - Husenawyia variety had higher vegetative fresh weight, root dry weight and fruit of mucilage content with the double recommended humic acid. While Al - Pteira variety had higher TSS% and Lauric acid% when used the double recommended concentration of zolfast.6 - The interaction between methods of application and concentrations of application substances showed superior effect on some studied parameters. Foliar application method was superior on addition to irrigation application with all concentrations except root fresh and dry weight and saturated fatty acids% (except Lauric acid) which were increased when added to the irrigation water to all concentrations of application substances. The same interaction did not revealed significant difference in stem diameter, Ca% and fruit fresh and dry weight.7 - The three way interaction factors studied in the experiment revealed an increase in growth parameter of both cultivars when humic acid and zolfast were added in their higher concentration (double recommended) by foliar application expect root fresh and dry weight and saturated fatty acids% (except Lauric acid) which were increased when added to the irrigation water. Al - Husenawyia variety was higher in all parameters with the use of higher concentration of humic acid and zolfast when applied with irrigation water or foliar application. The three way interaction revealed no significant difference in stem diameter, vegetative dry weight, Ca%, fruit fresh and dry weight, TSS%, percentage of oil and unsaturated fatty acids (Linoleic and Myristoleic).8 - Results of electrophoresis analysis revealed that the use of the doubled recommended concentration of humic acid and zolfast with irrigation water participated in building higher protein molecules in fruits to both cultivars. While the double recommended concentration of humic acid and zolfast did not show this trait when foliar applied.

Abstract: اجريت الدراسة الحالية في محافظة النجف في الفترة الممتدة مابين شباط 2012 لغاية تشرين الثاني 2013 في العيادة الاستشارية للجلدية في مدينة الصدر الطبية وكليتي العلوم والتربية للبنات في جامعة الكوفة. كان عدد المصابين بالجرب الذين ارتادوا العيادة الاستشارية لل | The present study was carried out in Najaf governorate, during the period from February 2012 till November 2013 in Dermatology Outpatient Clinic in Al - Sader Medical City, College of Science and College of Education for Girls in Kufa University. The number of scabietic patients who attended the outpatient clinic during February to November 2012 were 300 (168 males and 132 females). Their ages ranged from 10 to 65 years. They were included to show the prevalence of scabies. Sixty scabietic patients (out of 300 patients) who did not have allergic diseases, helminthic infections, previous attack with scabies, and/or getting any antihistamines drugs were included for human IL - 1?, TNF - ?, IL - 4, IL - 5 and total IgE assays using ELISA technique; superoxide dismutase (SOD) activity assay and eosinophils(%). These assays were applied on scabietic patients (who were divided according to onset of symptoms or duration of scabies symptoms into early and late scabietic patients) as well as healthy controls.Also Sarcoptes scabiei mite proteins were extracted. Then heat stable mite proteins concentration was determined by Bradford’s method. SDS - Polyacrylamide Gel Electrophoresis (SDS - PAGE) analysis was used. The activity of mite allergens was assayed by skin prick test (SPT) in 10 scabietic patients and 5 controls with 1.2 ?g/ml and 2.4 ?g/ml. House dust mite (HDM) antigens were skin prick tested in patients with scabies and controls.The prevalence of scabies in current study constituted 6.54% from all the dermatoses which attended the clinic. The males represented 56% and females were 44%. The age group (10 - 19) years was the highest prevalence of scabies (41.7%). Early scabietic patients represented 72% versus late scabietic patients were 28%. The results revealed that a highly significant elevation (p< 0.001) in serum cytokines (IL - 1?, TNF - ?, IL - 4 and IL - 5) as well as IgE, SOD and eosinophils (%) in the two groups of scabietic patients in comparison to the controls.Results of correlation demonstrated that IgE, SOD and eosinophils (%) were positively and significantly correlated (p< 0.001) with the studied cytokines in early, late scabietic and control groups. IgE was positively correlated with IL - 1?, TNF - ?, IL - 4 and IL - 5 in early scabietic patients, whereas, it had negative correlation with IL - 1?, TNF - ?, and positive correlation with IL - 4 and IL - 5 in late ones. SOD showed negative correlation with IL - 1? and TNF - ?, and positive correlation appeared with IL - 4 and IL - 5 in both scabietic patients. Eosinophils (%) were positively correlated with all the studied cytokines in two groups of scabietic patients.The results also revealed that SDS - PAGE profile of the parasite heat stable proteins consisted of protein bands with molecular weights ranged from less than 10 to over than 100 kDa. Skin test demonstrated that (7/10, 70%) and (8/10, 80%) of scabietic patients had a positivity against 1.2 ?g/ml and 2.4 ?g/ml of sarcoptic mite extracts, respectively when prick tested. HDM extract was found to be positive in (4/10, 40%) of scabietic patients; while controls revealed negative result.It can be concluded that scabies affect TH1 and TH2 immune response as well as SOD activity and eosinophils. Sarcoptic proteins contain heat stable allergens which able to cause immediate type - 1 hypersensitivity when 1.2?g/ml of mite protein is skin prick tested, and there is a cross reactivity between Sarcoptes scabiei and HDM allergens

The experiments had been performed in the animal house at Dept.of Biology of Education Fecundity at Tikrit Univ. from Jan. 2011 through July 2011. male rats were measured (250 - 350)gram, in age (16 - 20) weeks, (110) experimental, the rats were divided to (22) groups in which each consisted of (5) rats.The first experiment results have revealed the following : - 1 - The giving of Ferro alone and the Second dose has caused a noticed significant increase at the level of (p<0.01) in the total number of white blood cells (WBCs) and in the concentrations of each of Glucose(Glu), Total cholesterol (TC), Triglyceride (TG), Low density of lipoprotein - cholesterol (LDL - C), (VLDL - C), Malondialdehyde(MDA)and Peroxy nitrite(ONOO.) compared with control group, whereas it caused a high significant decrease at the level of (p< 0.01) in the concentration of each of High Density of lipoprotein of cholesterol(HDL - C), Total protein (TP), Glutathione(GSH) and ceruloplasmin(CP) and a decrease in sperm parameters. The two groups have also noticed a significant decrease of (p<0.01) in the concentrations of the melatonin hormone in the rats blood serum, growth Hormone and the Luteinizing hormone, in addition to the testosterone hormone and a decrease in the effectiveness of the catalase enzyme; taking into consideration the accumulative increase of Ferro element in the liver, kidneys and testes for both groups. As for the accumulation of copper, it has been noticed in the second dose group in liver, kidneys, and testes tissues, whereas the group of animals exposed to Ferro alone has noticed a high significant decrease in copper concentration in the three studied organs.2 - The giving of a first dose to white male rats (rattus ratus) has revealed a lack of significant differences in each of the total number of white blood cells, and the concentrations of most of biochemical parameters and sperm parameters, taking into consideration the significant decrease in the concentrations of each of (HDL - C), (GSH), (CP), (Mel), and (CAT). It has been noticed the occurrence of a significant increase in the concentration of (LDL - C). This group has also suffered a significant and insignificant increase in the Ferro accumulation in the studied organs, with a simple decrease of the accumulation of copper element in the three studied elements compared to the sound control group.3 - The giving of the three vegetal extracts which are Punica granatum L., Comellia sinensis L., and Olea europaea L. for animals exposed to second dose has caused a high significant decrease (p< 0.01). The effective power of extracts according to their arrangement and order in which first is Olea europaea L., then Punica granatum L., and lastly is Camellia sinensis L. have revealed positive significant changing in many biochemical parameters, with high significant increasing in (Mel), (GH), (LH), and (T) blood serum conc. in addition to the effectiveness of (CAT), compared to the group of animals exposed to second dose. All the sperm parameters in each of Olea europaea L. and Punica granatum L. have revealed a significant increase compared to the second dose group, whereas the Comellia sinensis L. has not revealed the occurrence of significant changes in most of the sperm parameters except in the percentage of active and moving sperms when compared with the second dose group.As for the accumulation of mineral elements, all the groups treated with vegetal extracts and exposed to second dose have witnessed a decrease in the accumulation of Ferro element in the liver, kidneys and testes tissues when compared with the second dose group, and this is also a fact concerning the accumulation of copper element.4 - The giving of Ferro alone and second dose have caused clear malady and tissue changes represented by diffusion of fat drops in a wide range between the liver cells. There has also been a poisonous and harmful effect of kidney tissue represented by the harm occurring in the disintegration and damage of the glomerulus and damage to the renal tubules, on the level of testis tissue, there have occurred huge damages in most tissue structures of the testes with a loss of most of the sperm formation stages, whereas the first dose group has not revealed any clear tissue changes compared to the sound control group. These changes have decreased when treated with vegetal extracts for each of Punica grantum L., Olea europaea L. and Comellia sinensis L. with the availability of Ferro and copper elements, since these elements have largely decreased the negative effects by affecting the three tissue levels which are liver, kidney and testes. Olea europaea L. has revealed a magnificent role on the reformative level of damaged tissues with a big similarity to the control group which exceeded both of Punica granatum L. and Comellia sinensis L. compared to the second dose group.Second experiment results : - 1 - The treatment of animals with hydrogen peroxide revealed very high significant changes at the level of (p<0.01), (p<0.05) in white blood cells, and in most of the biochemical and hormone criteria and sperm parameters which are similar to the effect of each of the Ferro dose alone and the second dose when compared with the sound control group.2 - The treatment of animals exposed to oxidative stress via hydrogen peroxide with Capsicum annuum L. and Musa paradisiacal L. separately Shown positive effect more than Prunus cersus L. and Prunus avium L. all juice led to the occurrence of noticed significant decrease at the level of (p<0.01) in the total number of white blood cells and in the concentrations of (Glu), (TC), (TG), (LDL - C), (VLDL - C), (MAD) and the root (ONOO.). This is compared with the group exposed to hydrogen peroxide alone, taking into consideration the occurrence of high significant increase in the concentrations of (HDL - C), (TP), (GSH), (CP) and in sperm parameters. There has also been noticed a significant increase in (p<0.01) in the concentrations of each of (Mel), (GH), (T) and (CAT)and (LH) compared to the group exposed to hydrogen peroxide alone.3 - The treatment with industrial tryptophan did not reveal any changes in the total number of most of the studied biochemical and hormone concentrations, but there has been witnessed an occurrence of significant decrease in the concentration of (LDL - C). As for the sperm parameters, the changes were between significant decrease and no significant changes when compared with the control group, with a significant increase in the effectiveness of enzyme CAT and concentration of hormone (Mel) in blood plasma with the sound control group.4 - The exposition of male rats (rattus ratus) to a period of continuous lightness led to the occurrence of several physiological and biochemical changes and to a high significant increase of (p<0.01) in sperm parameters and in the concentrations of hormones (Mel), (GH), (T), and (CAT) in blood plasma when compared with the control group; except for the occurrence of high significant increase in concentration of (LH). The darkness group revealed slight insignificant changes in most of the biochemical criteria and between the lack of changes in concentrations of (GH), hormone (T) and enzyme (CAT). This group also suffered the occurrence of high significant increase in concentration of (Mel) and a significant decrease in concentration of hormone (LH) when compared to the control group.5 - The giving (H2O2)caused several tissue changes in the livers of male rats (Rattus ratus). This has caused clear tissue and malady changes and similar to the Ferro and second dose groups. These changes have reduced when treated with Prunus cersus L., Prunus avium L., Capsicum annuum L. and Musa paradisiacal L. with the presence of hydrogen peroxide in that it greatly reduced the negative effects of hydrogen peroxide on the level of the three tissues of liver, kidney and testes. There is a lack of harmful tissue effects of industrial tryptophan on the tissues under study, when compared with the control group. In addition, both groups of rats exposed to durations of continuous lightness and darkness have suffered very huge tissue damage on the level of the three tissues, but the continuous lightness group suffered more damage when compared with the control group and continuous darkness duration.

Abstract: The present study aims to shed light on the follow up of acute leukemic (AL) patients at initial diagnosis and after treatment to assess the response and early relapse through evaluating the gene expression level of one of the major multidrug resistance genes which is the multidrug resistance 1 (MDR1) to investigate the possible association between level of MDR1 gene expression and the clinical outcomes and this may be considered as a potential marker for response to chemotherapy of acute leukemic patients. Furthermore, the current study correlates between the MDR1 gene phenotype and MDR1 genotype in three important coding regions (C1236T, G2677T/A, and C3435T considering the potential influence of altering MDR1 activity and its effect on therapy outcome as well as susceptibility to develop cancer.White blood cells (WBCs) isolated from 106 blood sample of acute leukemic patients were provided by Iraqi hospitals in Medical City. These samples were distributed as follows : 46 newly diagnosed patients with acute leukemia who had not received chemotherapy and follow - up 25 after 1st induction, 17 after 2nd induction and 8 at consolidation, with 10 blood samples of healthy voluntaries. Two comparative groups were taken included 46 sample of peripheral blood (PB) and 26 sample of bone marrow biopsy (BMB) in paraffin blocks to validate the level of gene expression compare to WBCs. For genotyping analysis, 56 of blood sample were taken to study genetic variation of MDR1 gene polymorphism. The samples preservation with TRIzol was done. Samples subjected to total RNA and DNA extraction, then molecular study by using reverse transcription, Quantitative Real Time - polymerase chain reaction (qRT - PCR) and direct sequencing, at Molecular Oncology Unit in Guy´s Hospital - Kings College / London.The study reached at the following results : 1 - The results showed age groups (20 - 39 years) were associated with acute myeloid leukemia (AML), while (13 - 19 years) with acute lymphoblastic leukemia (ALL).2 - The level of MDR1 gene expression showed high significant differences with WBCs compared to PB and BMB.3 - The clinical outcomes indicated that the rate of complete response (CR) of newly diagnosed acute leukemic patients was 19(41%), while 27(58.7%) was non - responder (NR).4 - Statistical analysis showed significant differences with NR at initial diagnosis in acute myeloid leukemia, while appeared after 1st induction in lymphoid type.5 - The results of positivity MDR1 gene expression were 10(21.7%) out of 46 newly diagnosed in acute leukemia, while 36(78.3%) were MDR1 - negative depend on (1.1±0.03) cutoff value.6 - The positivity MDR1 gene expression appeared mainly in non - responders patients at initial diagnosis, and with early relapse patients, after complete remission, in consolidation.7 - The MDR1 mRNA expression showed significant differences with high level in NR compared to CR patients at initial diagnosis. During treatment follow up the increased level of MDR1 gene expression in CR patients and appeared non - significantly with NR.8 - The results of MDR1 C1236T genotype and allele frequency showed that 1236CC wild type genotype and C allele were significantly frequent in healthy control. While CT heterozygous genotype frequency was highly significant in AML and no significant difference in allele frequency. ALL showed non - significant difference in genotype and allele frequency of MDR1 C1236T.9 - Odds ratio and 95% confidence interval (ORs and 95%CI) analysis showed no evidence associated with risk factor in MDR1 C1236T ALL carriers. While risk factor observed in AML with MDR1 1236CT carriers.10 - The results of MDR1 phenotype - genotype association indicate that MDR1 1236CC wild type was significantly high expression among healthy and it was aprotective genotype. While the MDR1 1236CT showed significant differences with high level of MDR1 gene expression in AML patients. Whereas ALL revealed significant differences in high level of MDR1 gene expression with MDR1 1236TT genotype. Both CT and TT were affected genotypes.11 - The results of MDR1 G2677T genotype and allele frequency indicated that 2677GA genotype significantly appeared with low frequency in healthy control with no significant difference in allele frequency. Both ALL and AML showed high significant frequency in 2677GT genotype. G allele frequency was showed significant differences in AML while non - significant in with ALL.12 - Odds ratio and 95% confidence interval (ORs and 95%CI) analysis showed the MDR1 2677GT genotype was associated with risk factor to developing ALL and AML. Whereas the GG appeared associated with AML only.13 - MDR1 phenotype - genotype association, indicate that MDR1 2677GA genotype was significantly high expression in healthy individual. While AML patients showed significant differences with high level of MDR1gene expression in 2677GT genotype. ALL showed significant differences with high level of MDR1 gene expression in MDR1 2677TT genotype.14 - The results of MDR1 C3435T genotype and allele frequency showed significant difference in genotype and allele frequency with heterozygous CT in both control and AML patients and mutant T allele. Whereas non - significant genotype and allele frequency with ALL.15 - Odds ratio and 95% confidence interval (ORs and 95%CI) analysis showed that the MDR1 3435CC genotype carriers associated with risk to developing ALL. While no risk factor associate with MDR1 C3435T variants to develop AML.16 - MDR1 phenotype - genotype association, indicate that the wild type 3435CC genotype was significantly high expression in healthy control. The MDR1 3453CT genotype showed high significance with high level of MDR1 gene expression inAML. While ALL showed significantly high level of MDR1 gene expression in 3435TT genotype.17 - The results of MDR1 genotype - phenotype association showed similar impact of MDR1C1236T, G2677T/A and C3435T genotypes in AML clinical outcomes. The MDR1 CT/GT/TT genotypes were associated in NR AML with high level of expression at presentation, compared to significant low level in CC/GG genotype. In contrast, CR patients were observed non - significant with MDR1 gene expression at presentation and significant with low MDR1CC/GG genotypes in post treatment. In regards to ALL patients the MDR1 TT genotype showed significant differences with high level of MDR1 gene expression in NR and CR ALL at presentation and significant only with NR at post treatment. So there was no clear evidence between MDR1 genotypes and clinical outcome with ALL.18 - The haplotype results showed that the three MDR1 C1236T, G2677T/A and C3435T genotype were linkage disequilibrium significantly with heterozygous haplotype B (CT - GT - CT) compared to A(CGC) and C(TTT). Also B haplotype appeared significantly with high level of MDR1 gene expression compared to A and C. According to the clinical outcome, haplotype B was observed significant differences in NR AML patients while other haplotypes were non - significant

Abstract: هدفت الدراسة الحالية الى تقييم انتشار جينات البيتا لاكتاميز ? - lactamases ومنها جينات البيتا لاكتاميز الواسعة الطيف lactamases - Extended Spectrum ? وجينات اخرى مثل جينات المقاومة للكوينولونات Quinolones المرتبطة بالبلازميدات plasmid mediated quinolones | The study aimed to evaluate the prevalence of plasmid mediated ? - lactamases including Extended Spectrum ? - lactamases and non - lactamases and study the horizontal gene transfer. A total of 800 of urine samples were taken from patient suffering from urinary tract infections had been collected during a period from February, to September of 2012, from the hospitals of AL - Najaf province. All the samples were cultured on MacConkey agar. From those 300 samples gave positive bacterial growth , 250 were lactose fermentative isolates, which were submitted to conventional tests including IMVIC and motility tests ultimately lactose fermentative, non motile isolates were candidate to Vitek 2 system to confirm the identification. the results revealed that there were 42 (16.8%) of isolates identified as Klebsiellae represented by Klebsiella pnumoniae ssp pneumoniae, 9(3.6%) of isolates diagnosed as Raoultella ornithinolytica, and 1(0.4%) for both K. pnumoniae ssp.ozeanae and Raoultella planticola. Screening tests were performed , disk diffusion test revealed different pattern of resistance, screening of ESBLS by MacConkey agar medium supplemented with 2 mg /l of Ceftazidime showed that 31 (58.5%) of isolates were initially ESBLS producers.Phenotypes confirmatory tests were conducted to different classes of antimicrobial agents, Disk synergism test revealed that 20(37.74%) of isolates were ESBLS positive, while Disk combination test by Ceftazidime + clav and Cefepime + clav revealed that 28(52.83%) and 43(81.13%) were ESBLS producers respectively, disk replacement test pointed that positive isolates were 26(49%), vitek2 system revealed 33(62%) of isolates were ESBLS producers.Imipenem - Ceftazidime antagonism test revealed that there was no isolate produce induced AmpC beta - lactamase, AmpC disc test revealed that no one of isolates were AmpC producer.The result of MHT(Modified Hodge test) revealed that all isolates were not Carbapenemases producers. Molecular study of different antimicrobial resistance genes were performed, the results reveald high percent of occurence as follow : blaTEM genes (90.6%), blaSHV gene(81.13%), blaCTX - M genes (88.6%), sul genes (88.6%), aac(6')Ib - cr genes (84.9%) and qnr - B genes (41.5%).the study also highlighted an association between studied genes. Finally many attempts to study of gene transfer by conjugation were conducted but all of them were failed, except one isolate (No. 5) was succeeded with frequency of conjugation (0.5×10 - 7). This study concluded that there were high prevalence of some plasmid mediated genes of isolates with clear multi gene resistance patterns as compared with some other genes which propose the high selective pressure of these genes and isolates might acquired resistance by mobile elements such as plasmids and integrons.

Statistics shows significant differences between them at ? =0.05. Symptoms of individual incident of the three Amoeba sorts were observed and recorded. Patients who had E. histolytica, severed from acute diarrhea that ranged between mucous and watery texture, which its color contrast between brown and reddish brown. They had bloody diarrhea and abdominal pain that ranged from severe to moderate colic. They had also slight temperature increase and weight loss. For those who had E.disbar, abdominal pain and frequent pale yellow diarrhea that semi - aqueous texture were recorded. Symptoms of : moderate yellowish brown snotty diarrhea, abdominal pain and, weight loss were observed for those who had E. moshkoviskii. R.T.PCR (Taqman Probe) was used to isolate samples and to investigate the three pathogenic virulence genes, which are Cystiene Proteinase, Amebopore, and Gal/Gal Nac Lectin. This was done in each of Amoeba’s species using R.T.PCR (Syber Green). According to it, E. histolytica possesses Cystiene Proteinase 1, Amebopore, and Gal/Gal Nac Lectin at 86.6%, 80.35%, and 42.8% respectively. Non - significant differences were found at ? =0.05 between them. For E.disbar, result shows existence of the same pathogenic virulence genes at percentages of 65%, 45%, and 20% respectively. Result presents significant differences among percentage of genes isolation for the pathogenic virulence factors at ? =0.05. E. moshkoviskii had these three pathogenic virulence genes at percentage of 33.3% by isolating the virulence genes except Gal/Gal Nac Lactin, there were significant differences among them at ? =0.05. This study was conducted to understand the molecular characterization confirmatory of the three types of insulators parasite using traditional enzyme chain polymerize reaction as a first stage to investigate the 18s ribosomal RNA covenantal. It represents personal heritage of the three types of amoeba. Depending on the same gene, developed tree were analyzed for Amoeba’s species using method of Neighber - Joining among different groups of the stains for each species separately using MEGA6 program. Knowing convergence rates of the used stains and international isolators from NCBI, Blast program was used.

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

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

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

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

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

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

The isolates diagnose depended on the cultural and microscobial characteristics and biochemical tests, serological diagnosis according to Lancefield method and assertion diagnosis according to (API - 20 Strep) was done to find (32) isolates of Enterococcus : (28) isolates of E. faecalis (87.5%), (3) isolates of E. faecium (9.4%) and one isolate of E.gallinarum (3.1%). - The sensitivity of E. faecalis was tested against (23) different antibiotics. The isolates showed resistance of about (100%) against Aztreonam, Amikacin, Co - Trimoxazole, Cephalexin and Cefotaxime, while the isolates were sensitive about (100%) against Amoxicillin, Nitrofurantoin, Imipenem and Ampicillin, while they showed a various resistance to another antibiotics involved in this study. - The ability of the isolates for producing the Beta - lactamase enzymes was tested by the standard rapid iodometric method. The results showed the disability of these isolates for producing the Beta - lactamase enzymes. - The production ability of E. faecalis for some virulence factors was evaluated. The results showed the ability of these isolates of adherence to the uroepithelial cells of human's urinary system were (93%), and (82.1%) were bacteriocin producer, and (28.6%) were hemolysin producer, and (43%) were gelatinase producer, and (10.7%) were lipase producer, and (35.7%) were capsule producer, and (14.3%) were cytolysin producer, while none of the isolates under the study showed the ability of haemagglutination.Histopathology type : (4.6 x 106) cell / ml concentration of the bacterial suspension of E. faecalis was used orally on mice and histopathological changes were examined after (3, 5, 7, 14) days of infection, which revealed the ability of bacteria for colonization and causing pathological lesions and many histological changes in the liver, kidney, small intestine and hearts of these animals. The damage in the animal tissues of the second group (treated with Streptomycin and EFU10) was more than that in the third group (treated with Streptomycin and EFS14), and fourth group (treated with EFU10 only). Generaly, the most important histopathological changes were the necrosis in some areas, and infiltration of inflammatory cells in infected tissues. These pathological lesions cause damage and decompose of tissues with distortion of their morphologies.

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

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

Abstract: اجريت الدراسة الحالية على جزء من بيئة نهر الفرات الممتد بين مدينتي الكفل والشنافية لمدة عام تقويمي من ايار 2013 ولغاية نيسان 2014 واختيرت اربعة مواقع مختلفة وموزعة على منطقة الدراسة شملت ثلاث محافظات هي : بابل - النجف - القادسية (الفرات الاوسط - العراق)، | The current study has applied on the Euphrates River for a full year from May 2013 until April 2014. Four sites selected along the river whithin three provinces; Babylon, Najaf, Al - Qadisiyah. Assessment of water quality done by using Canadian Council of Ministers of Environment (CCME) and Index of Biological Integrity (IBI) for the purpose of determining the validity and quality of its water for the General purpose and for Drinking and Irrigation.The physicochemical properties and biological (Phytoplankton) were studied during the study period. These properties were; temperature of the air and water, light penetration, electrical conductivity, salinity, turbidity, water current speed, total suspended and dissolved solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, carbon dioxide, total alkalinity, acidity, total hardness and ions of calcium, magnesium, sodium, potassium, and the sodium adsorption ratio, chlorides, sulfates, boron, nitrite, nitrate, phosphate, silica and some heavy metals such as cadmium, lead, zinc, copper, chromium, manganese in both phases : dissolved and particulate. results showed that the values of the physical and chemical factors ranged as follows : (7 - 47) C, (10 - 31) C, (14 - 177.5) cm, (1020 - 5600) µs/cm, (0.65 - 3.46) 0%, (0.07 - 129) NTU, (27.03 - 115.57) cm/s, (591 - 2985) mg/L and (0.001 - 0.128) mg/L, (7.04 - 8.8), (6 - 11.8) mg/L, (0.13 - 6.6) mg/L, (8.2 - 53) mg/L, (81.4 - 198) mg/L, (30 - 200) mg/L, (6 - 46) mg/L, (490 - 929.67) mg/L, (83.37 - 290.18) mg/L, (0.79 - 174.84) mg/L, (92.5 - 713) mg/L, (1.9 - 11.18) meq/L, (6 - 133) mg/L, (97.97 - 861.73) mg/L, (329 - 1040) mg/L (0.01 - 4.23) mg/L, (0.008 - 1.33) µg/l, (2.16 - 44.74) µg/L, (0.012 - 0.59) µg/L and (104 - 514) µg/L respectively.Concerning the heavy elements, the values of dissolved cadmium ranged between (undetectable - 0.075 mg/L) and it's particulate between (0.0043 - 0.2705) mg /L and dissolved lead between (undetectable - 0.0232 mg /L) and it's particulate between (0.0045 - 0.148) mg/L and dissolved zinc between (un - detectable - 0.0168 mg/L) and it's particulate between (0.0115 - 0.316 mg/L) and dissolved copper (undetectable - 0.0273 mg/L) and copper is particulate between (0.0062 - 0.063 mg /L) and dissolved chromium between (undetectable - 0.0193 mg/L) and the chromium is particulate between (0.0043 - 0.0449) mg/L and dissolved manganese (undetectable - 0.0256) mg/L and it's particulate between (0.0085 - 0.0739) mg/L.The biological tests include Qualitative and Quantitative Study on phytoplankton and also included calculating the total number of coliform way casting dishes by using the MacConkey Agar media.The number of diagnosed species of Phytoplankton was 295 species, belonging to 74 genera. The Diatoms Bacillariophyceae won the biggest part of it as it formed 160 species and 35 genera any rate (54.24%), followed by green algae (70 species belonging to 24 genera) and green algae (52 species belonging to 11 genera) then Euglenophyceae (10 species belonging to both sexes), while golden brown algae and algae Pyrrophyceae were less algal groups registered as belonging to the two single - sex. Some types of phytoplankton existed in most of the duration of the study, including Bacillaria paxillifera, Cocconies placentula, Cyclotella meneghiniana, Diatoma elongatum, Fragilaria virescence, Melosira ambigua, Synedra acus.The total number of phytoplankton is estimated between (104.9 - 4460.09) cell × 103/liter. An increase in the number of phytoplankton in July and January was observed clearly. The concentrations of chlorophyll - a were ranged between (0.0693 - 9.78 mg /L). While the total number of results for coliform were (5 - 281 × 103) cells/liter, The water quality of the evidence Account (Canadian model) using a number of physical, chemical and Biological properties. The results showed that the waters of the Euphrates are located within categories (Poor - Good) with respect to the public evidence of the quality of water of this river while it was located within categories (Poor - Acceptable) with respect to their use for drinking, While its use for irrigation purposes, it was clear that run river water data fall into two categories (Poor - Good). The results of the analysis of the main components Principal component Analysis (PCA) indicate that the nitrates and the total number of coliform and dissolved oxygen, phosphate, zinc, lead and Biological oxygen demand and pH are the biggest impact on the water quality of the index values of the variables of general purpose.These factors are responsible for the deviation index values, followed by turbidity and total hardness and electrical conductivity and temperature of the water, copper, chromium, and cadmium heat. But with the biggest impact of the index water quality factors for drinking purposes are chloride and electrical conductivity and total hardness, magnesium, turbidity and basal college, sodium, calcium, copper, sulfates, nitrates and coliform, zinc and dissolved oxygen, pH, manganese and lead followed by boron nitrite, cadmium, chromium and vital requirement for oxygen. While the chloride and conductivity electrical, the proportion of sodium, copper, zinc and adsorption of boron have greatest influence on the value of water quality index for irrigation, followed by manganese, cadmium, chromium, lead and pH.The phytoplankton index of Biotic Integrity (P - IBI) has been calculated using ten units including (relative abundance of green algae, green algae, pyrrophyta, Euglenophyta, Xanthophyta, Centralales, pennales, species richness index, the density of phytoplankton and chlorophyll a) The results showed that phytoplankton index of Biotic Integrity values ranging between (47 - 74) in the first position and (47 - 67) in the second location, and (45 - 76) in the third site and (45 - 71) in the fourth site. In other words, phytoplankton index of Biotic Integrity with estimating index (good - poor). The results showed the effectiveness of phytoplankton index of Biotic Integrity values in estimating the environmental changes.

The results of the present study showed that 56% of the subjects were pregnant and 44%were not. The highest percentage of the infected subjects was of 26 - 30 years old as 30.37% among the pregnant women and 36.35% among the non - pregnant women of the age mentioned above. The highest percentage 37.5% of abortion of the first period of pregnancy was in pregnant women, and 45.53% in non - pregnant women. The results of the study also showed more cases of infected women among those who bred animals in their living places as 69%. It is also found that the highest percentage of the infected women 64% were of those who use the running water for drinking. Moreover, it is noticed that there is an increase in the percentage of the infected women among the uneducated women 38%. The study showed that the percentage of the infection is proportional to residence 63%, the infection increase among women living in rural areas. The percentage of T - lymphocytes in peripheral blood of patients were also measured through measuring the percentage of the CD4+ and CD8+cells by using fluorescent microscope.The results showed a significant decrease (p<0.05) in this type of cells.The rate of percentage of CD4+ of the patient's were 31.704±0.116 while the rate of CD4+ in the peripheral blood of the control group was 62.260±0.237.The rate of percentages of CD8+ 19.382±0.080, whereas it was 31.680±0.307 of the control group.The rates of the percentages of CD4+ to CD8+ were also measured, the results showed a significant decrease (p<0.05) in the rate of the percentage in the patient's group 1.642 while it was 1.968 in the control group. The statistic analysis showed significant differences between these tow groups (p<0.05). The intensity of Zinc and Copper has been measured in the serum of the infected women via use of Atomic absorption instrument, a significant decrease (p <0.05) appeared in the rate of Zinc intensity in the serum on the infected women as compared with the control group.The rate of the intensity in patient's group was 4.65% ± 2.628µmol /l while in the control group it was 15.353± 1.640 µmol /l.A significant increase (p<0.05)was also noticed in the intensity of Copper in the patient's group (28.589±4.335 µmol /l)whereas it was 12.854±1.501 µmol /l in the control group. The index of the specific antibodies IgM and IgG related to Toxoplasma gondii was measured by ELISA method, a significant increase (p<0.05) was observed in the value of IgM and IgG in the patient's group as compared with the control group. The rate of index for IgM in the patient's group was 1.354±0.05 while it was 0.163±0.05 in the control group. The rate of value of IgG in the patient's group was 1.163±0.074 whereas it was 0.358±0.033 in the control group. In the present study, Toxoplasma gondii was isolated and diagnosed from human as first attempt, and then the infection was created in laboratory mice as an essential step for growing the parasite. The second step was studying the effect of some selected drugs on the experimental treatment for disease of toxoplasmosis created in the mice. The drugs are : Pyrimethamin, Clarithromycin, Spiramycin, Ivermectin.The results of the study showed the effects of these drugs on the tissue cyst formed in the brain and lungs. The number of tissue cysts in the brain of the mouse treated with pyrimethamin was 14.8 ±1.067 after 28 days. Significant differences appeared when this result compared with the control group in which it was 27.4±1.029. The number of tissue cysts formed in lung, tissue in the mouse treated with the same drug after the same period of the time was 6.2±0.583.This showed a significant differences as compared with the control group in which it was 10.2±0.583. No significant differences appeared between both groups as for the treatment by Clarithromycin antibiotic as far as the number of the tissue cysts formed in the brain after 28 days is concerned. The number was 23.8 ±0.86 as compared with the control group 38.6±1.029.The same compared is true of the lungs, tissue. The number of the tissue cysts was 23.8±0.86 as compared with the control group 28.4±1.805. Concerning the antibiotic Spiramycin, the results showed the effectiveness of it in decreasing the tissue cysts formed in the brain.The significant differences were (p<0.05), the rate of the cysts was 9.6±0.6 as compared with the control group in which it was 22.8±1.067.The same effectiveness appeared on the lungs, tissue as the rate of tissue cysts after 28 days of treatment was 4.6±0.509 as compared with the control group in which was 17±1.14 and the significant differences were (p=0.000).The Ivermectin drug showed a great effectiveness in minimizing the number of the tissue cysts formed in the brain and the lungs. The numbers of the tissue cysts formed after 28 days were 3.2±0.374 and 1±0.316 respectively; significant differences are observed when these numbers are compared with the numbers of the control group which were 22±1.843 and 19.4±1.435. Thus, the use of Ivermectin drug is considered as a pioneer and fruitful study since this drug has not been used for the treatment of Toxoplasmosis.

Abstract: اجريت هذه الدراسة للمدة من كانون الثاني 2011 ولغاية كانون الاول 2011 للمرضى الراقدين والمراجعين لمستشفى تكريت التعليمي وبعض المختبرات الخاصة في مركز المدينة وضواحيها والذين يعانون اعراض مرضية مختلفه ولفئات عمرية مختلفة ترواحت بين اقل من سنة الى 61 سنة، ح | This study was conducted for the period started from January 2011 until December 2011 on inpatients and outpatients of Tikrit educational hospital and some private laboratories at Tikrit city and surrounded suburbs. Symptoms of different diseases among various age groups varies between less than one year to 61 years. The tests used the (ELISA & PCR) and the analysis of the PCR - RFLP to discriminate the infection by assemblage of Giardia lamblia and differentiate between pathogenic amoeba Entamoeba histolytica and nonpathogenic Entamoeba dispar compared with microscopical examination. The result of present study showed that (75) person who represent (37.5%) were infected by Giardia lamblia and (75) person who represent (37.5%) were infected by E.histolytica/E.dispare complex, out of (200) stool samples which have been tested by microscopical examination. Epidemiological study showed no significant difference among the sex for the two species parasites whereas a high percentage for infection recorded in group at age (1? - 10) year for Giardia lamblia and E.histolytica / E.dispar complex reach to (60%, 36%) respectively. Regarding the place of living Giardia lamblia in rural area showed infection rate of (19.5 %), while infection rate by E.histolytica/E.dispar complex reaches (22.5%) in urban area. Statistical analysis shows a high difference of significance according the source of water supply. Tap water showed high incidence for initiating infection which reaches to (93.3%) by G.lamblia and (90%) for E.histolytica/E.dispar complex. For the infection rates and their relationship to the educational level, the results show that the highest rates of infection recorded in non - educated (52%) and (73.3%) of Giardia lamblia and E.histolytica / E.dispar complex, respectively. Depending on the sample texture, the result show that oily diarrhea is more correlate with infection reaches to (33.3%) of Giardia lamblia and the watery diarrhea form 40% by E.histolytica / E.dispar complex, while simultaneous occurrence of both symptom (colic and loss of appetite) are the most symptom synchronized with infection records (44%) for Giardia lamblia and (36%) for E.histolytica / E.dispar complex. The percentage of infection by Giardia Lamblia in this study depends on the test results of the ELISA was (20%), while the percentage of infection E.histolytica/E.dispar complex was (6.7%). Testing has shown sensitivity compared to microscopic examination reaches to (22.6%) and (8%) for both parasite respectively, while the test showed a high specificity which reaches the rate (93.3%) and (100%) for both parasites respectively. Result of PCR showed a percentage of infection by E.dispar about (32%) (64 sample) from the total samples, whereas it does register any cases infection by E.histolytica. By counting the results of the PCR for the three genes (ssu rRNA + TPIA + GDH) they show a total infection by Giardia lamblia which was (10.5%) (21 samples). This study recorded percentage of infection Giardia lamblia depending on the result of the three Genes separately amounted to (4%), (5%), (3%) for (ssu rRNA, TPIA, GDH) respectively. According to the result of the analysis PCR - RFLP for GDH gene by using the enzyme NIaIV, it did not record any infection by Giardia lamblia (assemblage A), whereas (6 samples) recorded (100) by Giardia lamblia (assemblage B), by using the enzyme Rsal to determine the secondary assemblage shows that the total (6 samples) infected there are 5 samples carrying infection by two type of secondary assemblage returning to the assemblage B (assemblage BIII +BIV) and only one sample infected with (assemblage BIV). To determine the assemblage and secondary assemblage for the parasite result compared with amplification of TPIA gene with lysis by enzyme for the resulting amplification for GDH gene, resulting a ratio of (14.3%) for a sample infection by both assemblage (A+B) and secondary assemblage (BIII+BIV) together, and a ratio of (57.14%) infection by assemblage A only and (21.4%) infection by secondary assemblage (BIII+BIV) together and (7.14%) infection by BIV only.

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.

Abstract: 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 present study designed to investigate the levels of genes expression of five genes panel (MGB1, CK19, MUC1, miR - let7a, and miR - 195) in circulating free mRNA and miRNA from blood of breast cancer patients versus noncancerous samples (benign tumor and healthy controls) to establish a biomarker panel potentially useful for early detection and progression of disease. The expression patterns of the identified genes were then compared with certain clinical features (age, lymph node status, and tumour size).Blood samples from 55 patients with different stages of newly diagnosed invasive ductal carcinoma were provided by certain Iraqi hospitals. Two control groups were used in this study; 10 samples of patients with benign breast tumors, and 20 samples from healthy donors. The samples preservation with TRIzol was done. Samples subjected to total RNA extraction, and then molecular study by using reverse transcription and real time PCR at Molecular Oncology Unit in Guy´s Hospital - Kings College / London.The study reached the following results : 1. The patients’ age range was 24 - 70 years and the median was 49 years with high frequency of patients in the range of 40 - 59 years. According to the family history, 50(90.91%) of patients were have negative family history. According to the clincopathological features (lymph node status and tumor size) the percentages of patients with multiple lymph nodes and tumor size 2.0 - 2.9 cm were the highest groups, which showed statistically highsignificant differences.2. For MGB1 gene expression, the result showed that 30(54.5%) patients were MGB1 - positive while 25(45.4%) patients were MGB1 - negative.According to malignancy status the percentage of patients with high level of MGB1 gene expression 22(40%) was significantly high. In correlation with age groups there was statistically no significant differences in the levels of gene expression with age. In correlation with clincopathological features, lymph node status showed that the highest percentage of MGB1 positive patients 18(66%) were multiple for lymph node status, and the tumor size results showed that there was decreasing in the MGB1 geneexpression with increasing of tumor size. 3. For CK19 the results of present study showed that 41(74.54%) patients were CK19 - positive, while 14(25.46%) patients were CK19 - negative.According to malignancy status the percentage of patients with high level of CK19 gene expression 30(54.45%) was significantly higher in compare with benign tumor patients and healthy controls. In correlation with age groups there was statistically no significant differences in the levels of gene expression with age. In correlation to the clincopathological features, lymph node status results showed that the highest percentage of CK19 positive patients 24(88.89%) were multiple for lymph node status, and there was increasing in the CK19 gene expression with increasing of tumor size.4. Mucin 1 (MUC1) gene expression results showed that the percentage of MUC1 - positive breast cancer patients 72.73%(n=40) was significantly higher when compared with benign tumor patients and healthy controls. According to the age groups the results showed no significant correlation with patients age groups. The clincopathological features results showed that the highest percentage of MUC1 positive patients 84.21%(n=16) have few lymph node status, and there was statistically significant association between the increasing of MUC1 gene expression and tumor size. 5. The miR - 195 gene expression results showed that the percentage of patients with positive miR - 195 gene expression 83.64%(n=46) was significantly higher than patients with negative miR - 195 expression 16.36%, the study also showed that the percentage of high miR - 195 expression samples 69.09% (n = 38) was significantly higher in compare with benign tumor patients and healthy controls. According to the clincopathological features, patients with multiple and few lymph node metastasis were found to have significantly the highest percentages of miR - 195 expression, while the tumor size results showed that there was increasing in the miR - 195 gene expression with increasing of tumor size. 6. The percentage of miR - let 7a - positive breast cancer patients 81.82% was significantly higher, when compared with miR - let 7a - negative patients 18.18%. In correlation to the clincopathological features, results showed no significant correlation in miR - let7a gene expression levels with patients age groups, for lymph node status, the results showed that the highest percentages of let 7a positive patients were those with multiple lymph node and few lymph node metastasis. The tumor size results showed that there was increasing in miR - let 7a gene expression with increasing of tumor size.7. According to genes combinations, three genes combination (CK19, miR - 195 and miR - let 7a) was significantly positively expressed with percentage of 60%(33/55), which reflect their potential diagnostic and prognostic value.8. The study concluded that the three genes combination (CK19, miR - 195 and miR - let 7a) may have potential applications as a diagnostic and prognostic markers for breast cancer.

Abstract: The study consists of three parts related with patients of CRC as in : 1 - Molecular part 2 - Cytogenetic and molecular genetics part and 3 - Immunological part. In addition of their relatives of clinical and pathological diagnosis, genus, and tumor locations in 150 of Iraqi patients confirmed with CRC collected from Teaching Hospitals of some Iraqi governorates. The percent of male to female (54.66% / 45.43%) and the aged range of study were 16 to 80 years.The first part consist a study of five types of genes related with CRC represented by MLH1, MSH2, APC, K ras, and SMAD7 genes. Some of these genes develop with germline mutations as in MLH 1 exons1 and 15 so as MSH2 genes. While the rest genes related with a sporadic of CRC. All these genes were amplified by conventional polymerase chain reaction (PCR) for study the types of the mutations and their defect of these genes on CRC. The APC exon11and K ras exon1 genes were processed by single strand conformational polymorphism (SSCP) technique. The results of PCR - SSCP technique for two genes represented by appeared three types of bands, which were (AA), (AB) and (AC) bands. The important band was (AB) which constitutes the variability region represented by 84.2% and 44.82% in patients for both genes. The results of patients with mutated bands with high significant differences(P?0.05).compared with healthy control. Patients carried these bands subjected to PCR - Sequences technique. The analysis results for APC gene sequences were substitutions mutations type of single nucleotide polymorphism (SNP) change Cytocine to Thiamin (C>T) at 1972 location of genome. While the analysis results of Kras gene appeared two types of mutations, substitution and frame shifts represented by deletion mutation and so as appeared stop codon mutation.The other genes represented by MLH1, MSH2, and SMAD detected by direct PCR - Sequences. The results analysis of MLH1 gene, exon (1and 15) represented by nucleotides change with high frequencies of substitution mutation through exon1 at different locations of nucleotides. So as frame shift mutation type deletion through exon15. While for MSH2 gene, exon 6 from 6.66% represent by deletion mutation. A spread study for SMAD7 gene, exon4 were done through 30 patients average age 52 years (male to female 56.7% : 53.3%) confirmed colorectal adenocarcinoma compared with 15 healthy. A mutation of 20% of (SNPs) were identified.The second part which represented standard conventional cytogenetic and molecular genetics were done through peripheral blood culture (PBC). The study showed increasing of mitotic index (MI) in patients with significant differences (P?0.05) compared with healthy controls indicating for increasing of proliferation of the lymphocytes division. The study showed some chromosomal aberrations with significant, the majority of aberrations were higher significant in dwarf and aneuploidy chromosomes so as elongation chromosomes revealed significant differences (P?0.05) between patients and healthy. The appeared of Polyploidy chromosomes, with significant differences (P?0.05), that’s seem to be good indicator for cancer disease. The molecular genetics alterations which dependent on cytogenetic investigation were done through deletion of long arm of 5 chromosome which APC gene is located. The test elucidates the importance of inactivation (deletion) of APC gene in elicited of colorectal cancer. The study of 20 patients, were investigated by fluorescent in situ hybridization (FISH). The results showed 60% patients which have 5q arm deletion of (+). And (5%) have two deletions (++) which was a male aged less than 60 years. The results analysis explained significant differences (p?0.01) between studied group and deletion (+) of arm 5q. A correlation represented by significant differences (p?0.01)through dysfunction of APC gene deletion of 5q were found with high percent among sporadic adenocarcinoma 58.3%, with less in attenuated familial adenomatous polyposis (AFAP) and familial adenomatous polyposis (FAP) represented by the (25%), and (16.7) respectively.The last part related with immunological test were done by detection of tumor markers represented by Carcino Embryonic Antigen (CEA), IL - 33 and IL - 31.These markers represented a confirmative indicators for colorectal adenocarcinoma which were tested by ELISA technique in (79) patients confirmed with CRC of male and female. These tumor markers in tested with patients showed high significant differences (p?0.01) compared with healthy controls. Another immunological test for detection of Human papilloma virus (HPV) type 18 E6 gene expression in CRC by Immune histochemistry technique (IHC) in 71 (FFPET) of CRC. The results of this study showed there were a correlations between patients and adenocarcinoma positive HPV18 E6 infection 43.7% of patients infected with virus, with high significant differences (p?0.01) and higher infection in female (67.7%) than male (32.3%). So as a correlations were found between HPV18 E6 expression and tumor tissue locations, explained by high percentage 45.2% in rectum.While a tumor marker was (CD8+) was used to determine its role in human immune surveillance in tumor regions of CRC so as with regions which were infected by HPV. The study revealed high significant differences between healthy control and studied groups which have (CD8+) positive infiltration in tumor origins through detection by (IHC).In conclusions diagnosis of CRC can be detected by special genes like K ras gene through professional PCR processing, compact with tumor markers, so as Fluorescent in situ hybridization (FISH) technique provides a precise method which can be used for detection of alteration of molecular and cytogenetic related with CRC.

Abstract: This study aimed to determine the frequency of Salmonella Typhimurium and its multi - drug resistance (MDR) status as a diarrheal causative pathogen in children younger than five years old, as well as to investigate the role of four probiotic microorganisms(L.acidophillus, L.casei, S.cerevisiae, S.boulardi) in controlling such infection.For this purpose, 128 stool samples of patients (76 males and 52 females) was included in this study. They were children suffering from diarrhea and fever who admitted to the “Central Pediatric Hospital” in Baghdad during the period from April to September, 2012. Their ages ranged from six days up to five years.The immunological effects of probiotics and MDR S. Typhimurium isolate in the experimentally infected and probiotic - treated mice were investigated via assessing the level of ten cytokines (IFN - ?, IL - 1?, IL - 4, IL - 10, IL - 12, IL - 17A, IL - 21, GM - CSF, RANTES and IP - 10) in the lavage of small intestine. Accordingly, five groups of mice were used in the in vivo part of this study; Mice in group I received probiotic for 7 successive days, challenged with S. Typhimurium on day 8, and dissected on days 14 and 21. Group II wassimilarly treated, but the probiotic was continued for 14 days. Group III was given the probiotic only, and group IV was challenged with S. Typhimurium, while group V was the control.Results obtained in this study could be summarized as follows : 1. Out of 128 stool samples, S. Typhimurium was isolated and identified in 9 samples only (7.03%). All isolates were totally resistant to nalidixic acid, with the exception of one isolate which showed intermediate sensitivity.Furthermore, only one of these isolates (symbolized B) was found to be resistant to three antibiotics (ampicillin, amoxicillin and nalidixic acid).Therefore, this isolate was considered as an MDR isolate and selected for further experiments in the study.2. When the susceptibility of MDR S. Typhimurium isolate B was further assessed in vitro by using four probiotics (Saccharomyces cerevisiae, S. boulardi, Lactobacillus acidophilus and L. casei), results showed that S.cerevisiae and L. acidophilus were the most efficient by recording the highest inhibition zones (12.6 and 16.3 mm, respectively), therefore, they were further investigated for their anti - S. Typhimurium effects in vitro and in vivo. 3. By using the unconcentrated and (one - fold, two - fold, three - fold) concentrated filtrates of these two probiotics, it was found that the three - fold filtrates were most efficient in their antibacterial activity by recording the highest inhibition zones (25.0 mm for S. cerevisiae and 31.0 mm for L. acidophilus.4. Significant increases in the values of liver index were observed in mice of group I treated with L. acidophilus at 21 days (10.73%) compared to the corresponding group treated with S. cerevisiae (7.41%) or other four groups. For spleen, index value in L. acidophilus groups was higher than the corresponding groups in S. cerevisiae. Mice treated with a probiotic alone or in a combination with the pathogen showed significant increases in the spleen index values of all groups compared to the untreated mice (group V).5. Both probiotics were effective in reducing S. Typhimurium colony forming units per plate (cfu/plate) in the liver and spleen. In liver, mice in group IV showed a count of 224.4 cfu/plate, which was significantly higher than any count in groups of L. acidophilus and S. cerevisiae. Group II mice recorded better results than group I mice, while the lowest counts (21.6 and 27.8 cfu/plate for L. acidophilus and S. cerevisiae, respectively), were observed at day 21.6. The ten investigated cytokines showed different levels in the small intestine wash; such differences were subjected to the group of mice underinvestigation and type of probiotics used. In addition, variations in IFN - ?/IL - 4, IFN - ?/IL - 10, IL - 4/IL - 10 and IL - 17A/IL - 10 were also observed.

Abstract: صممت الدراسة الحالية لتوصيف الانماط الجزيئية والمظهرية للنمو والفعالية الانزيمية للانزيم المحلل للبروتين والتنوع الوراثي وعلاقته بالتعبير الجيني بين عزلات الفطر الجلدي.Trichophyto rubrum ولهذا الغرض جمعت 150 عينة سريرية (قشطات جلدية (80), اجزاء شعر (60) | The present study was designed to characterize the morphological and the molecular patterns of growth, enzymic activity of proteases, genetic diversity and their correlation with gene expression among strains of Trichophyton rubrum. 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.

Abstract: لازال البحث مستمرعن ايجاد متغيرات جديدة قد تساعد في تشخيص ومتابعة مرض السكر وهو من المجالات المهمة في ميادين البحث العلمي حيث ركزت بعض الدراسات على حالة الانسولين بينمراكزت بحوث اخرى على صورة الدهون والشدة التاكسدية كاسباب للسكري. اجريت هذه الدراسة لمرض | The search of a new parameters for monitoring and even prediction of diabetes mellitus (DM) are still an important issue in many research fields. Some studies focused on the role of insulin status, while others concentrated on lipid disturbances or even oxidative stress disorders in the diabetes. This study was conducted on randomly selected 68 type 2 diabetic patients (27 Males and 41 Females) attending the diabetes mellitus center in Al - Sadder Teaching Hospital in Al - Najaf province, Iraq and a group of 20 apparently healthy subjects (10 Males and 10 Females) were included as a control group. The study was carried out from February 2013 to July 2013. The age of patients and control groups were range of 35 - 65years. The concentration of fasting blood glucose, cholesterol, triglyceride, LDL, VLDL, HDL, Apelin, Omentin, Vaspin, Visfatin and BMI were estimated in patients and control groups. The results show significant increase (P?0.05) in fasting blood glucose, cholesterol, triglyceride, LDL, VLDL, Apelin, Vaspin and Visfatin levels in patients compared with control groups, also the results show significant decrease (P?0.05) in HDL and Omentin level in patients compared with control groups. The results revealed that all biomarkers (Apelin, Omentin, Vaspin and Visfatin) not significant difference (P>0.05) in patients at different ages. The results also revealed that biomarkers (Apelin, Vaspin and Visfatin) levels increase significantly (P?0.05) in males than females in both patients and control groups, while the result of omentin level reveal no significant difference (P>0.05) between males and females in both patients and control groups. The results also revealed that significant increase (P?0.05) in BMI in patients compared with control groups. The results also show that biomarkers (Apelin, Vaspin and Visfatin) concentration increase significantly (P?0.05) with increasing BMI in males than females compared with control groups, while the result of omentin concentration show no significant difference (P>0.05) in patients and control groups and show lower significantly increase (P?0.05) in females than males compared with control groups. The results have been shown significant positive correlation (P?0.05) between biomarkers (Apelin, Vaspin and Visfatin) and FBG, cholesterol, triglyceride, LDL and VLDL in patients (males and females), while the results have been shown significant negative correlation (P?0.05) between biomarkers (Apelin, Vaspin and Visfatin) and HDL in patients (males and females). The results also have been shown significant negative correlation (P?0.05) between omentin and FBG, cholesterol, triglycerides, LDL and VLDL in patients (males and females), while the results have been shown significant positive correlation (P?0.05) between omentin and HDL in patients (males and females). The results also have been shown no significant correlation (P>0.05) between Vaspin and FBG in patients (males and females). The present study concluded that Apelin, Omentin, Vaspin and Visfatin levels maybe that could be adopted as markers for detection and diagnosis of diabetic patients type 2.
