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.

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

Two species, Saprolegnia parasitica and Saprolegnia ferax, have been isolated from rivers, lakes and fishes. The physical and chemical environmental characteristics have been measured. The types above have been examined to extract the DNA. The (PCR) technique has been used to examine the presence of protease enzyme. The results of isolation and identification showed that the percentage of the two species were 64% in rivers areas 40% in the lakes areas and 50% in fishes. The rates represented the examined samples which were 60 samples. AS well as isolates was in rivers 16 isolation and in Lakes 10 isolates either in fish was 5 isolation and thus the total isolates 31 isolation, The S. parasitica species is more apparently found during (February, 2014), the number of samples was 12, the less presence of this species in (April, 2014), where the number of sample, was 3. The S. ferax species is more apparently presented in (February, 2014), the number of samples was 10. The less presence was in (April, 2014), the number of samples was 2. The results showed that the number of isolation of Saprolegnia spp. study area as it was S.parasitica species in were 6 in rivers, 2 in lakes, and 3 in fishes. The second species, S. ferax showed number of isolations which were 10 in rivers, 8 in lakes, and 2 in fishes. The PCR examination has used to detect the rDNA gene which responsible for proteases gene and whether it is found in the two species of fungi. The express way has been used to extract DNA and according to the instructions of manufacturer company. The concentrations of DNA in first species were 121.8 - 73.0 mcg/microliter and purity 1.87 - 1.80.In the second species the concentrations of DNA were 2360.4 - 166.9 mcg/microliter and purity 2 - 1.75. The results, by using PCR technique, showed that the percentage of protease in first species was 25% in rivers. In lakes and fish was 100%.Concerning the second species, the percentage of enzyme was 42% in rivers, 40%in lakes, and 50% in fishes. It can be concluded that there is a diversity in fungi species with respect to study areas and enzyme secretion in the stages of fungi infection. The enzyme is more apparently found in S.parasitica species compared with S.ferax species.

Abstract: من مجموع مئة عينة سريرية جمعت من مصادر مختلفة شملت الحروق والدم والجروح ومسحات انفية, تمكنت 90 عزلة من النمو على اكار المانيتول الملحي , ومن بينهم 40(44.4 %) عزلة عائدة لبكتريا المكورات العنقودية المنتجة للانزيم المخثر للبلازما و50 (55.5%) عائدة لبكتريا ا | Out of one hundred clinical samples were taken from different sources which include burns, blood cultures, wounds and nasal swabs infections ; 90 isolates developed growth on mannitol salt agar. Among these, 40 (44.4%) were Coagulase positive (Staphylococcus aureus) isolates, 50 (55.5%) belong to coagulase negative staphylococci in which Staphylococcus epidermidis isolates were 30(60%). The pattern of antibiotic susceptibility of Staphylococcus epidermidis isolates to 12 antibotics (Amoxiclav, Ceftazidim, ciprofloxacin, clindamycin, Erythromycin, Gentamycin, Imipenime, Penicillin G, Tetracycline, Rifampin , Methicillin, and Vancomycin) were determined using disc diffusion method. The results revealed that resistance to Penicillin G10 and Amoxiclav (Amoxicillin - clavulanic acid) were 100%, Methicillin were 93%, Erythromycin were 90%, Gentamycin and Clindamycin were 70%, Tetracycline and ceftazidim were 75%, Ciproflaxacin were 60%, Rifampin were30%. 95% of S.epidermidis isolates were sensitive to Imipenim and 5% of them were intermediate resistant, while these isolates showed 90% sensitivity to vancomycin. 19 isolates were multidrug resistance. Minimum inhibitory concentration of S.epidermidis isolates to vancomycin, was determined. The results revealed that (12) S.epidermidis isolates (40 %) were vancomycin resistant, the MIC of them were between 256 ?g\ml and 32 ?g\ml, (4) S.epidermidis isolates (13.3%) were intermediate resistance, the MIC to 3 of them were 16 ?g\ml and the last was 8 ?g\ml. Some virulence factors of VRSE and VSSE were detected including the hemolysin, protease, lipase and urease. The S. epidermidis isolates were produce hemolysin, protases, lipase and urease, were 100%, 100%, 25%, 100% respectively in VRSE, while in VSSE 100%, 100%, 60%, 100% respectively. The isolates were subjected to polymerase chain reaction (PCR) technique in monoplex pattern to amplify resistant incoding gene : the vanA, vanB and autolysine gene aae gene. The results by this study showed that 12 (40%) S. epidermidis isolates gave the implicone size (1030 base pair) of the vanA gene. However the results of MIC and PCR were similar but no any isolates gave product for presence of vanB gene. All S.epidermidis were able to produce implicone size(858bp) of aae gene. The effect of vancomycin resistant S. epidermidis on cell autolysis activity was detected by whole cell autolytic assay.The results revealed that there was significant difference among three isolates, the VSSE isolate (S.epidermidis 22) have the highest autolytic activity in the presence of antibiotic, followed by the VRSE isolate (S. epidermidis 1) and the VISE isolate (S. epidermidis14) which was the lowest autolytic activity with the presence of antibiotic. The result of transmission electron microscope (TEM) showed that the VRSE isolates (S.epidermidis 1) have thicker cell wall followed by VISE (S.epidermidis 14) isolates.However, the VSSE (S.epidermidis 22) didn't showed any cell wall thickening.

Abstract: Studies have linked FOXP3 and TGF - ? expression to the outcome of certain cancers. FOXP3 is a marker known to be expression in T - regulatory cells while TGF - ? is a secreted protein usually detected in the extra cellular matrix.The present study aimed at focusing on the identification of immune markers namely FOXP3 and TGF - ? with their expression patterns in lung cancer patients as a useful tool to predict disease progression.Also it is aimed to design molecular evaluation of m RNA expression of both FOXP3 and TGF - ? in peripheral blood mononuclear cells and bronchial (brush) cells of patients with lung cancer and benign lesions, using qRT PCR; determining the T - reg level in the peripheral blood employing the High Rsolution Melting (HRM) as a novel method to detect Treg - specific demethylated region (TSDR); molecular DNA analysis of somatic mutation of exons 3, 6, 7 of FOXP3 in patients with lung cancer tissue and benign lesions and immunohistochemical (IHC) estimation of FOXP3 and TGF - ?1 in T - reg and cancer cells in formalin fixed paraffin embedded(FFPE)lung cancer tissue and benign lesions.Blood samples were collected from 30 patients with newly diagnosed, non small cell lung carcinoma and 30 patients with benign lesions.Patients were recruited at The Specialized Surgery Hospital and Oncology Teaching Hospital/Baghdad.Samples from 16 apparently healthy donors were used as control during the period from June 2012 to June 2013. The samples preservation with TRIzol reagent were subjected to molecular study including RNA and DNA extraction; reverse transcription; RT - PCR; HRM assay and DNA sequencing were done in the Molecular Oncology Unit/Guys and ST Thomas? s hospital/ King College/London/UK.The expression level of FOXP3 was high in 16(61.5%)in lung cancer cases.A significant difference was noticed between cancer cases from one side and benign lesions or healthy control on the other side p<0.05.Mean of FOXP3 expression(fold change)was significantly high(2.64±0.09)in cancer cases than in benign cases(1.32±0.04)and healthy control(1.38±0.06)with p<0.05.A significant association between high expression level and >60 age and squamous cell carcinoma in cancer cases P<0.05.The expression level of TGF - ? was high in 16(61.5%)in lung cancer cases.A significant difference was noticed between cancer cases from one side and benign lesions or healthy control on the other side p<0.05.Mean of TGF - ? expression (fold change) was significantly high (6.27±0.56) in cancer cases more than healthy control (2.87±0.09) with p<0.05.The association was significant between TGF - ? expression level (high and low) and age>60in cancer and benign groups (p<0.05), while no significant association with gender and cancer types were noticed.For FOXP3 mRNA expression in bronchial brush cells, the result showed no significant difference between the mean fold change of malignant(3.57 ± 0.06) and benign(4.02 ± 0.06) patients. The low expression was predominated both in cancer and benign cases. No significant differences were found between FOXP3 expression (high and low) and age; gender ; cancer types..According to FOXP3 T - reg specific demethylated region detection, results showed that the mean percentage of FOXP3demethylation in lung cancer patients (4.32 ± 0.04) was significantly higher than in benign lesions (3.22 ± 0.02) patients andhealthy controls(3.33±0.04). A positive correlation coefficient with high significant, was found in the group of cancer samples (R² = 0.6653;r = 0.69;P : 0.0017)on correlating percentage of Treg and demethylation of FOXP3 from one side with its m RNA expression on the other side.In benign lesion group was(R² = 0.5334;r= 0.59;p= 0.0027), While in the control group a positive correlation but a weak significance was found (R²= 0.2383;r=0.28;P=0.0437).FOXP3 gene sequencing revealed high frequency of missense mutations c.715 GTA>CTA : V 239 L in 17 (94.44%) in malignant sample and non cancerous cases7 (87.5%)without statistical differences. Missence mutations were also detected in exone 3 in 3(16.67%) cancer cases and in 1(12.5 %) benign lesion.No missense mutations could be detected in exon 6. Intronic mutations and silent mutation were variable in three exons without statistical differences. Many cases of adenocarcinoma have shown multiple mutations either of missense or Intronic types. Missense mutations of exon 7 were correlated significantly with an age of 60?years. Exon 3 mutations were significantly associated with adenocarcinoma. Positive FOXP3 Immunohistochemistry (IHC) staining in tumor cells was associated with high missense mutations frequency 10(55.55%) in exon7, while in exone 3 was 2(11.11%). Negative FOXP3 IHC staining in the tumor cells was associated with seven missense mutations in exon7 and one (5.55%) in exon 3, in addition 4(23.53%) cases of the exon 7 missense mutations were associated with negative FOXP3 expression in lymphocytes.The result showed that FOXP3 by using IHC staining was positive in 21(70%) of nuclei of cancer cells, and 22(73.3%)in Treg infiltrates.The positive cancer cells and Treg infiltrates associated significantly with age>60 (p<0.05).No significant association was found withgender, cancer type, while there is association with moderate differentiation compared to poorly differentiation (p<0.05). High frequence of FOXP3 expression score 3 and high intensity were appeared in nuclear cancer cells compared to benign lesions cells, while Treg infiltrates with score 1 and high intensity was high frequency in malignant and benign.The result showed that TGF - ?1 by using IHC staining was positive in 25(83.3%) in the cancer cells and 21(70%) in stromal cells. No significant difference was noted between positive expression in malignant and benign lesions p>0.05.No significant association was noticed between positive cells expression and age, gender, cancer type and differentiation p>0.05. High frequency of TGF - ?1 expression score 3 and high intensity in malignant cells and benign. Also stromal cell expression score 3 and high intensity were predominated in malignant and benign lesions. The high and moderate intensity expression was more frequent in matrix surrounding cancer cells compared to non cancerous.Total agreement and kappa coefficient between FOXP3 and TGF - ?1were poor in malignant and benign epithelial cells and stroma, while the perfect agreement was between expression of TGF - ?1in stromal cells

Abstract: The present study aimed to understand the correlation between serum level of nine cytokines (IL - 1?, IL - 1RA, IL - 2, IL - 4, IL - 6, IL - 10, IL - 12, IFN - ? and TNF - ?) and their genetic polymorphisms at 16 gene positions defined by sequence specific primer - polymerase chain reaction (SSP - PCR) in pulmonary tuberculosis (PTB) patients, and in addition HLA - DQB1 gene polymorphism was also defined by SSP - PCR to determine their role in susceptibility or resistance to M. tuberculosis. Finally, serum level of cortisol was also determined in the patients.Ninety four Iraqi Arabs PTB patients (70 males and 24 females) were enrolled in the study. They were referred to the Institute of Chest and Respiratory Diseases in Baghdad for diagnosis and treatment during the period May - October 2012. A control sample of 80 apparently healthy individuals was also included and matched patients for gender (60 males and 20 females) and ethnicity. The results are summarized in the following : 1. A significant increased serum level of IL - 1? (24.16 ± 8.82 vs. 3.20 ± 1.18 pg/ml), IL - 1RA (41.31 ± 6.64 vs. 16.85 ± 5.50 pg/ml), IL - 2 (17.63 ± 3.53 vs. 7.80 ± 1.10 pg/ml), IL - 4 (9.56 ± 2.60 vs. 3.81 ± 1.70 pg/ml), IL - 10 (34.49 ± 4.60 vs. 7.61 ± 1.70 pg/ml), IL - 12 (25.16 ± 5.85 vs. 7.70 ± 1.12 pg/ml) and TNF - ? (22.52 ± 4.41 vs. 4.97 ± 1.15 pg/ml) was recorded in PTB patients compared to controls. Also, Cortisol serum level was significantly increased in patients (215.47 ± 1.33 vs. 38.63 ± 1.74 ng/ml).2. Cytokine gene polymorphism analysis revealed that neither genotypes nor alleles of IL1A - 889, IL2 - 330, IL2+166, IL4 - 590, IL4 - 33, IL6+565, IL10 - 819, IL10 - 592, IL12B - 1188 and TNF - 238 genes showed a significant variation between PTB patients and controls. In contrast, the frequency of TT genotype of IL1RN gene at position mspal 11100 showed a significant (P = 0.004) increase in PTB patients compared to controls (65.9 vs. 43.7%). For IL4 - 1098, the frequency of TT genotype was also significantly (P = 0.048) increased inpatients (82.9 vs. 70.0%). At position - 174 of IL6 gene, a significant (P = 0.002) increased frequency of GG genotype was observed in patients (55.3 vs. 31.2%). For IL10 gene, only GG genotype at position IL10 - 1082 was observed with a significant (P = 0.045) increased frequency in patients (18.1 vs. 7.5%). At position - 308 of TNF gene, a significant (P = 6.9 x 10 - 5) decreased frequency of GG genotype was observed in patients (60.6 vs. 87.5%), while GA genotype was significantly (P = 1.3 x 10 - 4) increased (38.2 vs. 12.5%). Finally, the frequency of AA genotype of IFNG gene at position +874 demonstrated a significant (P = 0.006) increase in PTB patients (55.3%) compared to controls (33.7%).3. To determine the impact of cytokine genotypes on cytokines serum level, PTB patients and controls were distributed according to their serum level in the three genotypes of each cytokine. It was found that CC genotype of IL1RNmspal 11100 in patients was observed with the highest IL - 1RA level (52.16 ± 5.81 pg/ml) compared to TT (41.39 ± 3.23 pg/ml) or TC (38.10 ± 4.54 pg/ml) genotype. The TT genotype of IL2 at position - 330 also showed the highest level of IL - 2 (22.16 ± 4.31 pg/ml) compared to TG (17.59 ± 3.40 pg/ml) or GG (13.68 ± 3.53 pg/ml) genotype in patients. The IL4 - 1098 TT genotype showed the highest level of IL - 4 in patients (10.38 ± 2.21 pg/ml) compared to TG (6.09 ± 1.20 pg/ml) or GG (3.93 ± 0.80 pg/ml) genotype. For IL10 gene, the GG genotype of IL10 - 1082 recorded the highest level of IL - 10 (40.67 ± 2.96 pg/ml), which was significantly different from AA genotype (26.66 ± 5.65 pg/ml). At position - 308 of TNF gene, serum level of TNF - ? in GG genotype of patients demonstrated a significant increased mean compared to genotype GA (24.76 ± 1.30 vs. 19.15 ± 1.12 pg/ml). At position - 238, TNF GG genotype showed a significant increase level of TNF - ? (23.02 ± 2.91 pg/ml) in patients compared to AA genotype (17.18 ± 1.53 pg/ml) of patients. Finally, IFNG+874 AA genotype was observed with the highest IFN - ? level in patients (11.07 ± 1.12 pg/ml) compared to AT (7.97 ± 1.81 pg/ml)or TT (6.10 ± 2.20 pg/ml) genotype. In contrast, no such differences were observed in controls.4. Out of the five encountered HLA - DQB1 alleles, DQB1*03 showed a significant (P = 0.005) increased frequency in PTB patients compared to controls (71.3 vs. 50.0%). It was also observed that heterozygosity at such gene locus was significantly (P = 0.03) more frequent in patients than in controls (93.6 vs. 82.5%), while homozygosity was observed with a less percentage frequency in patients compared to controls (6.4 vs. 17.5%) and the difference was also significant (P = 0.03).Accordingly, it is possible to conclude that the cytokine profile was deviated in PTB patients, and such deviation was correlated with the genotypes of some cytokines, which might also together with HLA - DQB1polymorphism confer the individual an immunogenetic predisposition to develop M. tuberculosis infection.

Abstract: اجريت الدراسة الحالية للفترة من 1شباط 2015 لغاية 3شباط 2016 وجمعت خلالها عينات المرضى المصابين بالحزام الناري من قسم الامراض الجلدية في العيادات الاستشارية في مستشفى مرجان التعليمي للتحري عن بعض الجوانب المناعية في المرضى, وكان العدد الكلي للمرضى 50 مريضا | This study was conducted during the period from 1st February 2015 to 3rd February 2016, and the samples were collected from dermatology department of the consultant clinic in Marjan Teaching Hospital to investigate certain immunological markers of patients with shingles. The total number of patients were whose their ages ranges were 14 - 80 years. Age group (40 - 61) years have the highest percentage of infection reaching 46%.The immunofluorescence test for Varicella Zoster virus - specific IgG showed 48 out 50 are positive(96%). The higher percentage of infection with shingles was in female (54%), while male patients the percentage was(46%).The results showed that patients with blood group (O+) have 50% of infection rate.When CD4 was investigated by ELISA test , the results showed that the mean± SD of serum level of CD4 in shingles patients and control group is (6.70± 0.97 and 9.36±2.02) ng/ml respectively. The concentration of CD4 was lower in patients with shingles than healthy control group, while concentration of CD8 and CD56were higher than healthy control group ( the mean± SD of serum level of CD8 in shingles patients and control group was 21.42±5.43 and19.11±3.29 ng /ml respectively, whereas the mean ± SD of CD56 concentration in shingles and control group were 107.58± 40.39 and 67.59 ± 36.31 ng/ml, respectively).The results also showed that the concentrations of IFN ? and TNF? were lower in patients with shingles compared with non - infected persons , as the following : the mean± SD of serum level of IFN ? in shingles patients and control group was 184.31±21.95 and 218.03±26.21 pg /ml respectively, and the mean ± SD of TNF? concentration in shingles and control group were 51.55± 5.14 and 62.35 ± 6.74 pg/ml, respectively. For IL 10, the concentration was higher in patients with shingles than that in the healthy control group; the mean± SD of serum level of IL 10 in shingles patients and control group was12.42±5.59 and 4.47±0.90 pg /ml respectively. This study was concluded following : • Gender represents a risk factor for the occurrence of shingles mainly at ages over 40 years old (higher in females than males).• Varicella Zoster virus specific IgG is a sensitive and specific test that can be used for the laboratory diagnosis of shingles.• Varicella Zoster virus reactivation has a suggested link with decreased level of soluble CD4 molecules and, for lesser extend with increased soluble CD8 and CD56 molecules in patients serum. • Blood group O+ might be consider as a risk factor for reactivation of VZV infection as the majority of patients were within this blood group.• A diminished role of the inflammatory TH1 cells in reactivated shingles patients is more likely as evident by the reduced concentration of IFN? and TNF? profiles. The Treg cells (CD4+ CD25+) seems to play a role in such reduction of TH1 proinflammatory cytokines as evident by the significant elevation of IL10 in shingles patients.

Abstract: اجريت الدراسة لتقييم مناعة المجتمع لكلا النازحين والمقيمين الملقحين بلقاح فيروس الحصبة ضد خمج الحصبة في محافظة بابل. لذا تضمنت هذه الدراسة معايرة الحالة المناعية في امصال النازحين والمقيمين محافظة بابل مع عزل وتشخيص فيروس الحصبة من الحالات المشتبه بها. ت | The study was conducted to evaluate the herd immunity for both the displaced and residents vaccinated with measles virus vaccine against measles infection in Babylon governorate. Therefore this study includes the evaluation of the immune status in sera of Babylon governorate displaced and residents with specific aspect for isolation and identification of measles virus from suspected cases. The immune response was evaluated by means of ELISA test (enzyme linked immunosorbet assay) for titration of IgM and IgG immunoglobulin level, in addition to evaluation of perforin level in the sera of 90 measles vaccinated individuals included in this study (50 displaced and 40 residents) from different areas in Babylon governorate, that were collected during the period extent from January up to April of 2016. Data about individuals were fixed according to information of formula including age, sex, geographical location, place displace of displaced and the vaccination date. Successful virus isolation from suspected cases on two types of cells culture included Vero cells line and chicken embryo fibroblast was carried. The titer of the isolated virus on Vero cell line reached (105.8 TCID50 / 0.1ml),which was higher than the titer of the virus isolated on CEF which reach (105.4 TCID50 / 0.1ml) after the third passage of the virus. The isolated virus was confirmed by indirect immunofluorescence technique.The age of subjects included in this study ranged from <1 year up to 24 years old. The results revealed that 15 (30%) have positive IgM index in sera of displaced, whereas residents sera sample shown only 6 (15%) positivity. Howover, all 90 (100%) subjects of both groups showed positive IgG index. The results of the present study showed that there were no significant difference of perforin level in sera of refugees and residents at p<0.05.Assaying of immune response against measles virus by measuring IgM immunoglobulin in sera of vaccinated displaced and resident with measles vaccine reflected a highly significant difference between two groups which reached 0.43 mIU/ml in sera of displaced in comparison with residents sera which reached 0.34 mIU/ml. The result showed also high significant differences in IgM between females and males. The females sera IgM levels of displaced and residents were higher than its level in males sera which reached 0.47 mIU/ml and 0.35 mIU/ml, respectively, in comparison with male sera level which reached 0.40 mIU/ml and 0.32 mIU/ml, respectively. According to age group, the highest IgM value was recorded in displaced and residents sera in age group 10 - 14years (0.50 mIU/ml) and 5 - 9years (0.36 mIU/ml) respec - tively. Whereas the lowest IgM serum value was detected in age group <1 year (0.34 mIU/ml) and 15 - 19years (0.31 mIU/ml) for displaced and residents subjects. According to geographical location, the highest IgM level was detected in sera of displaced from Tal Afar city (0.44 mIU/ml) followed by displaced from Ramadi (0.41 mIU/ml) and the lowest IgM value was detected in sera of displaced from Mosul city (0.33 mIU/ml). Whereas the highest IgM value in sera of residents in the subjects of Al - Mahaweel city (0.37 mIU/ml) followed by subjects of Hilla and Al - Qasem city (0.29 mIU/ml and 0.28 mIU/ml) respectively. For IgG serum immunoglobulin the results revealed that there was no difference in significant levels in both group population. But according to age groups significant difference between displaced and residents was detected at p <0.05 in which the 1 - 4 years old showed the highest IgG serum level in both group (1.98 mIU/ml and 2.18 mIU/ml) respectively. While the lowest IgG sera value was recorded in displaced age group of < 1 year old (0.60 mIU/ml) compared with residents age group of 20 - 24 years old (1.65 mIU/ml).It could be concluded that the results showed that the displaced do not have any effect on the residents of the province of Babylon for measles as a result of the good immunization by Babil Health directorate following to the Ministry of Health.

Abstract: التهاب المفاصل الرثوي (Rheumatoid Arthritis) مرض جهازي التهابي مزمن يصيب المفاصل وتحديدا الاغشية الزلالية والتراكيب المفصلية، والذي يحدث للعديد من الناس وبنسبة تقارب 0.5 الى 1% من السكان في العالم. لوحظ خلال الدراسات الوبائية لمرض التهاب المفاصل الرثوي | Rheumatoid arthritis (RA) one of the most common systemic autoimmune diseases characterized by chronic joint inflammation and subsequent joint destruction. To date, it well known that RA is characteristic of the expansion of the synovium and infiltration of the inflammatory cells coupled with destruction of adjacent articular cartilage and bone. This is strongly dependent on CD4 T cell. CD4 Cells stimulate monocytes, macrophages, synovial fibroblasts, and other cells to produce cytokines such as tumor necrosis factor - ? (TNF - ?, interleukin - 1 (IL - 1), IL - 6, IL - 15, IL - 17 and metalloproteinases that produce tissue damage. TNF is a major inflammatory cytokine contributing to the pathogenesis of RA, which provides rational for development of anti - TNF biological agents in the treatment of RA.Recently have shown that IL - 37 is a key cytokine in regulating inflammatory response, mainly by inhibiting the expression, production, and function of proinflammatory cytokines. Objectives This study planned to evaluate the association of TNFRII and CD4 enhancer genes polymorphisms in development and severity of RA in Iraqi patients, evaluate IL - 37 in patients with RA and investigate the correlation between IL - 37 levels with disease activity and relation of inflammatory parameters (ESR, CRP, ACPA, and RF) with TNFRII, CD4 enhancer genes polymorphisms.Patients and methods This study was performed during the period from May to September 2015. The patients were attending the out patients' Clinic in Medical City/Baghdad Teaching hospital/rheumatology unit and the laboratory ELISA tests were done in nursing home hospital laboratory, polymerase chain reaction (RFLP) analysis was performed in the specialist private molecular laboratory (ASCO Lab) in Al - Harthia / Baghdad. Fifty patients and 50 apparently healthy control individuals, Patients received disease modifying anti rheumatic drugs (DMARDs) and newly diagnosed patients.The diagnosis of RA patients has performed under the supervision of rheumatic disease consultant physician at the consultation clinic of Baghdad teaching hospital of the medical city. Blood samples had taken from RA patients to measure (ESR), white blood cells count and hemoglobin. Also, analyze the serum levels of ACPA, RF screen CRP and estimate the levels of IL - 37 in patients and healthy individuals using ELISA test kits. TNFRII and CD4 enhancer genes polymorphisms genotyping had achieved by polymerase chain reaction restriction fragment length (PCR - RFLP).Results The results showed the estimation of RF by screening test revealed that its mean level was high among RA patients (168.87+31.62) in comparison with apparently healthy control (4.96+0.71) with highly significant difference (p<0.01). There was a higher positivity of Anti CCP in the patients sera (114.85+21.06) in comparison with apparently healthy control (1.71+0.13) (P<0.01). while the estimation of CRP showed that its level was higher among sera of RA patients (38.39+4.31) in comparison with healthy control group (16.49+2.51) (P<0.01). Furthermore, the ESR level in RA patients were higher than apparently healthy individuals (52.96+3.68) and (10.44+0.74) respectively with significance (P<0.01).The frequencies of the MM, MR, RR genotypes of TNFRII gene polymorphisms were 60%, 32%, 8% in RA patients and 52%, 42%, 6% in controls. There were no significant differences in the genotypes frequencies polymorphisms of the TNFRII 196 MR polymorphism between apparently healthy control and RA. The frequencies of AA, AG, GG genotypes of CD4 10845 A/G in patients was 36%, 42%, 22% and 8%, 44%, 48% in control group. There were significant differences in the genotypes frequencies polymorphisms of the CD4 10845A/G polymorphisms between apparently healthy control and RA patients (p<0.01). AA genotype were significantly more likely to develop RA (OR=1.355). There was significant increase in disease activity and severity in patients carries AA genotype (p<0.01).IL - 37 levels were elevated markedly in RA patients (101.31+10.41) compared with apparently healthy control (43.90+0.91) (p<0.01). More importantly, IL - 37 showed a significant correlation with disease activity (CRP) in RA patients (p<0.05). Also, IL - 37 show non - significant relationship with (MM, MR, RR) exon6 TNFRII in RA patients compared with controls, and non - significant difference between level of IL - 37 with CD4 10845 A/G genotypes compared with healthy control.Conclusion All findings suggested that TNFRII - 196R genotypes not associated with RA diagnosis. In addition, genetic polymorphisms at the CD4 enhancer gene are one of important factors that associated with susceptibility and severity of RA and can serve as a genetic marker for the risk of development of RA.

Abstract: This study was designed as a retrospective research. A total number of (90) formalin - fixed, paraffin embedded tissues were studied. Malignant and normal thyroid tumors tissue blocks were collected from the archives of histopathology laboratories of different general hospital including ALYarmouk Teaching Hospital (Baghdad), Baghdad Medical City Teaching Hospital as well as many private laboratories in Baghdad, during the period from May 2013 to May 2014. These cases include ? Thirty tissue specimens from patients with papillary thyroid cancer. ? Thirty tissue specimens with benign thyroid lesions as control thyroid tissues group. ? Thirty (30) thyroid specimens were obtained from the normal thyroid tissues from the same those totally - thyroidectimized patients for thyroid papillary cancer (PTC) and have served as the second control group for this study. This study was therefore a paired case - control design. The sections were stained by hemotaxyline and eosin staining so as to confirm the diagnosis and assure that the intervening sections ( that were specified for the in situ hybridization and Immunohistochemistry study have containing the questioned tissues from papillary thyroid cancers and benign thyroid tissues (control group).After histopathological sectioning of these thyroid gland tumors and staining by Hematoxylin and Eosin, a final definitive diagnosis was done by histopathologist consultant. The practical part of this study was designed in four pathways : 1. Molecular detection of Epstein - Barr virus in those tissue blocks were performed by using ultra - sensitive version of in situ hybridization (ISH) for detection of EBV - EBERs. 2. To perform immunohistochemical study to demonstrate EBV - latent gene (LMP1, EBNA - 2) in the papillary thyroid cancer compared to control group. 3. To perform immunohistochemical screening study to demonstrate the over expression state of p53 - tumor suppressor gene in those tissues with papillary thyroid cancer compared to control group. 4. To perform immunohistochemical screening study to detected the CD8 and CD56 in tissues with papillary thyroid cancers compared to control group. The obtained results are summarized as follows : 1. The mean age of patients with papillary thyroid cancer and simple nodular goiter was (39.87&41.13) years respectively, with standard deviation ±(11.773,9.243) years. 2. In this study, the percentage of the females with papillary thyroid cancer was higher (86.7%; 26 cases) than the percentage of their PTC - male counter parts (13.3%; 4 cases). The patients whom sub totally thyroidectimized for simple noduler goiters , the percentage of females was also higher (73.3%; 22 cases) than the percentage of their male counter parts with simple noduler goiters ( 26.7%; 8cases). Female / male ratios of the patients with PTC and simple noduler goiters were 6.5 and 2.75 respectively. 3. The percentage of EBV results in the total group of PTC was (50%) while the percentage in the total group of normal thyroid tissue was (26.7%) and lastly in the total simple nodular goiter group was (10.0%). 4. The positivity rate of EBV EBERs - ISH technique in the total group of PTC was (30%), where as its percentage in NTT tissues was (16.7%) and in SNG tissues was (3.3%). 5. The percentage of positive - EBNA - 2 IHC technique in the total group of PTC was (20%), where as its percentage in NTT tissues was (10.0%) and in SNG tissues was (6.7%). 6. The percentage of positive - EBV - LMP - 1 - IHC technique in the total group of PTC was (43.3%), where as its percentage in NTT tissues was (20.0%) and in SNG tissues was (6.7%). 7. Mutated P53 - protein was detected in 28 cases (70%) of the studied cases. Twelve cases (30.0 %) showed negative IHC reactions. 8. The highest total percentage of CD8 - IHC reactions (21 cases; 70%) was found in those with papillary thyroid cancer followed by normal thyroid tissues cases ( 5 cases; 16.7%) and then ( 2 cases : 6.7%) in simple nodular goiter. 9. It was found that the highest percentage of CD56 - IHC reactions was in those with normal thyroid tissues (25 cases; 83.3%) followed by an equal percentages of CD56 - IHC reactions in either thyroid papillary or simple nodular goiter (2 positive cases; 6.7%, each). 10. The importance of CD56 marker has been found to play a role or it may be better to be used as a negative - diagnostic biomarker for papillary thyroid cancer in differentiating it from other malignancies as well as benign lesions of the thyroid gland, individually as well as in combination with other markers for clinical evaluation of those patients. 11. The evident high mutated p53 - over expression, as reflected by abnormal gene product, among papillary thyroid cancer patients indicates for a pivotal role of such genetic mutation in their carcinogenesis as well as could be useful in the clinical evaluation of patients with papillary thyroid cancer, too. 12. The high coexistence of p53 - mutation with EBV in PTC could point for participation of EBV - transformation genes in the p53 activation in high proportion of PTC. 13.The high percentage of CD8 lymphocytes in EBV - positive PTC as compared to their EBV - negative counterparts could reflect the participation of specific cellular immunity against both, the papillary thyroid cancers and this EBV infection during the initiation and progression of EBV - associated papillary thyroid cancers.

Abstract: Human herpesvirus 6 (HHV - 6) is largely ubiquitous double stranded DNA viruses within the betaherpesvirinae subfamily and of the genus Roseolovirus.HHV - 6A and HHV - 6B infects very high percentage of population around the world, primarily during childhood through respiratory droplets. HHV - 6 has been found out in many types of cancers : lymphomas, leukemia, cervical cancer, and brain tumors.This cross - sectional case control study was carried out in Baghdad Teaching Hospital and National Center of Hematology - AL - Mustansiriyah University - Baghdad, for the period from 1 September 2013 to 1 April 2015.The aims of the study were to explore the seropositivity rate of HHV - 6 antibodies among Iraqi patients with different hematological malignancies using different laboratory assays, beside, the molecular determination of plasma viral DNA load by quantitative polymerase chain reaction (qPCR).The study included 109 patients with different hematological malignancies; 24 patients with acute lymphoblastic leukemia (ALL), 30 patients with acute myeloid leukemia (AML), 11 patients with Hodgkin lymphoma (HL), 39 patients with non hodgkin lymphoma (NHL) and 5 patients with chronic lymphocytic leukemia(CLL). All patients were newly diagnosed and enrolled before receiving chemotherapy. The age range was between 14 - 80 years. Fifty three (48.6%) and 56 (51.4%) patients were males and females, respectively. The diagnosis of their malignancies was based on either bone marrow aspirate biopsy and lymph node biopsy as well as cytochemical investigations. Additionally, 59 apparently healthy blood donors were enrolled as control group. The age range was between 18 - 59 years, twenty eight (47.4%) and 31 (52.6%) were males and females, respectively.The serum anti - HHV - 6 IgG was detected by indirect immunofluorescent technique (IFAT) as well as by enzyme linked immunosorbant assay (ELISA).While, the serum anti - HHV - 6 IgM was detected by ELISA only. The detection and quantification of plasma viral DNAemia was carried out by quantitative polymerase chain reaction. Serological as well as molecular assays were done in Central Public Health Laboratory in Baghdad. The highest IFAT positivity rate was among patients with CLL (100%), followed by patients with AML (83.3%), and the least positivity rate was among patients with NHL (64.1%) compared to that of healthy control. Generally, the total anti - HHV - 6 IgG by IFAT was insignificantly higher among patients compared to healthy controls (74.3% vs 61.0%, p=0.074). The anti - HHV - 6 IgG positivity rates by ELISA were insignificantly higher in all groups of haematological malignancies except in patients with AML in whom it was significantly higher compared to healthy controls (96.7% vs 72.9%, p= 0.007 ). A part from AML, the highest anti - HHV - 6 IgG by ELISA was among patients with ALL (87.5%) followed by patients with NHL (84.6%), and the least was among patients with CLL (80.0%) compared to healthy control. Generally, the total anti - HHV - 6 IgG positivity rate detected by ELISA was significantly higher compared to IFAT in patients (p= 0.013) as well as in healthy control (p= 0.0005).The results of anti - HHV - 6 IgM positivity rate as detected by ELISA was significantly higher in patients with AML (36.7%, p=0.0004), and patients with HL (27.7%, p= 0.038) compared to healthy controls (6.8%). Whereas, other groups of hematological malignancies showed insignificantly higher positivity rate versus control group. However, the highest positivity rate was among patients with AML (36.7%), and the least positivity rate was among patients with CLL (0%). Generally, the total ELISA anti - HHV - 6 IgM positivity rate was significantly higher in patients versus healthy controls (22.0% vs 6.8%, p= 0.011). The results of PCR showed that 5 out of 109 patients had detectable HHV - 6 DNA in the plasma. The highest detection rate was among patients with HL (27.3%), followed by patients with ALL (4.2%), and then patients with AML (3.3%), while the virus was not detected in other disease categories as well as in healthy controls. The plasma viral load (mean ± SD) among the three Hodgkin lymphoma patients was 1.4± 0.3*102 particle/milliliter.The study concluded that the seropositivity rate of HHV - 6 infection is highly prevalent among Iraqi patients with hematological malignancies compared to healthy population. However, primary or reactivation infection as determined by anti - HHV - 6 IgM in patients as well as healthy individuals is relatively low. Furthermore, the HHV - 6 DNA detection rate as well as plasma viral load among malignant patients before receiving immunosuppressive treatment were low.

Abstract: Worldwide, cancers of the urinary bladder are complex and involve genetic abnormalities and may be due to different environmental chemical carcinogens, as well as chronic infection like Schistosomiasis, all these will allow normal transitional cells to become cancerous which are typically transitional cell carcinoma(TCC).This study was conducted at AL - Yarmouk and Baghdad Teaching Hospitals in Baghdad from June 2013 to April 2014, of which urine and bladder tissue were taken from 57 bladder cancer patients and 80 controls to assess Interleukin - 8 (IL - 8), Matrix MetalloPeptidase - 9 (MMP - 9), Bladder Cancer - Associated Protein (BLCA - 4),Toll - Like Receptors (TLR - 2and TL - R4) level among them and to evaluate their roles in cancer development.One hundred thirty seven Iraqi individual were divided to 28(20.43%) newly diagnosed and 29(21.16%) recurrent bladder cancer patients (relapse), 40(29.19%) apparently healthy volunteers and 40(29.19%) autopsies (apparently normal urothelium), of whom urinesample and tissue biopsy were collected, clinical diagnosis of patients carried out by cystoscopic and histopathological examination, the mean ±SD age of bladder cancer patients were (63± 9.3) with (M : F ratio7.1 : 1).Predominant cancer type was Transitional cell carcinoma (TCC). According to risk factors of bladder cancer, out of 57 bladder cancer patients, 34(59.64%), 29(50.87%), 9(15.78%), 7(12.28%), 6(10.52%) were smoker, had UTI, history of Schistosomiasis, family history ofcancer and stones respectively. In this study 30 patients had non - muscle invasive bladder cancer, most of them (21) had newly diagnosed tumors, and only 9 had recurrent disease, as well as, 27 patients with muscle - invasive bladder tumor, just 7 had newly diagnosed tumors and 20 with recurrent disease.According to the result of ELISA technique, the mean±SD urine level IL - 8(pg/ml) for recurrent bladder cancer patients was 359.6±170.1pg/ml, for newly diagnosed was 265.95±139.09pg/ml and for healthy volunteers was 62.04±37.66pg/ml. The mean ±SD concentration of urine MMP - 9(pg/ml) was 7368.3±1730.19pg/ml for recurrent, 6176.8±2366.9 pg/ml for newly diagnosed and 1131.53±1554.80 pg/ml for healthy volunteers. Mean±SD Level of urine BLCA - 4 (ng/ml) for recurrent was 1.45± 0.26 ng/ml, for newly diagnosed was 1.30± 0.22 ng/ml and for healthy volunteers was 1.02±0.067 ng/ml. Urine level of these markers was significantly higher in recurrence group when compared with newly diagnosed and these levels decreased in normal volunteers which was statistically significance (P<0.001 for IL - 8, MMP - 9and BLCA - 4),also there was a significant increase in urine IL - 8 level according to grade(P=0.0002) and muscle invasion(P= 0.0009) as well as BLCA - 4 showed this significant increase in high grade(P=0.0001), and muscle invasion(P=0.0001),but no significant difference was found in the level of urine MMP - 9 with grade(P=0.23) and muscle invasion(P =0.069)In comparison, IL - 8 and MMP - 9 IHC staining of bladder tissue, showed low expression in cancerous tissue with no significant difference between cancer and normal urothelium(P=0.140 for IL - 8, P=0.265 for MMP - 9 ), and unrelated to grade, muscle invasion and recurrence.Significant increase in TLR - 2 and TLR - 4 expression in bladder cancer tissue than in normal urothelium (P=0.0001 for each), and according to grade and muscle invasion, TLR - 2 showed significant over expression in high grade than low grade (40.7%vs36.6%) with P=0.018, muscle invasion than non - muscle invasion (44.4%vs33.3%) with P value of 0.02, while TLR - 4 was none significantly correlated with grade andmuscle invasion. As well as, there was no correlation between these receptors with tumor recurrence.In regard to risk factors, Smoking, schistosomiasis and family history showed correlation with study marker in different manner as, IL - 8 was significantly highly expressed in smoking associated bladder cancer group, as well as patients with family history of bladder cancer showed high expression IL - 8, for Schistosoma associated TCC patients and UTI they demonstrated a statistically significant high expression of TLR - 2 p= (0.0001).From this study we conclude that urine IL - 8, MMP - 9and BLCA - 4 measured by ELISA showed specificity in diagnosis of bladder cancer, besides that, urine IL - 8, MMP - 9 and BLCA - 4 have a role in discrimination between newly diagnosed vs recurrent, with a significant association between urine IL - 8 with BLCA - 4 (P= 0.0001) and IL - 8 with MMP - 9 (P= 0.005) in patients with recurrent bladder cancer. Urine IL - 8 and BLCA - 4 concentration were statistically with significant increase in high grade than low grade and muscle invasion than non - muscle invasion, On the other hand, bladder cancer cells over express TLR - 2 and TLR - 4,while TLR - 2 showed correlation with high grade and muscle invasion,TLR4 did not show such correlation. Lastly, IL - 8 and MMP - 9 staining showed low expression in tumor tissue of different grades, stages and groups.

Abstract: Epstein Barr virus (EBV) is ubiquitous virus which infects the majority of the human population and is the causative agent of infectious monocleosis and a variety of B - cell tumors including Hodgkin lymphoma, Burkitt lymphoma, human immunodeficiency virus - associated lymphomas and post - transplant lymphoproliferative disorders , this virus expressed many protein and it is associated with a variety of B - cell tumors. Recently many studies have suggested a causal relationship between EBV and chronic lymphocytic leukemia (CLL). A prospective study of thirty samples of formalin - fixed, paraffin - embedded tissue of bone marrow aspirates samples and blood from newly diagnosis BCLL of 30 patients and our control included : 1) 20 bone marrow of patients who they have hematological disease other than leukemia as control. 2) Blood serum from healthy controls to study the level of IL - 10 and IL - 8. The present study conducted at Baghdad Teaching hospitals and the National Center of Hematology from September 2013 to Jun 2014. In this study we investigated the association between EBV and CLL. The detection of EBV encoded RNAs (EBER1,EBER2) by in situ hybridization and also latent membrane protein - 1 (LMP - 1) and EBV nuclear antigen - 2(EBNA2) by immunohistochemistry and detection for the level of Interleukin n (8 and 10) in the serum of CLL patients by ELISA. In situ hybridization study revealed that all the controls were negative for EBERs and 46.7% patients were found to be EBERs positive. There was a correlation between positive EBERs and tumors stage and also EBERs and IL10 and with LMP - 1 and EBNA - 2. Immuno - histochemical method was used to demonstrate the rate of (LMP - 1 and EBNA - 2) in CLL patients where a positive results of EBNA2 and LMP1were found in (43.3 % and 56.6s %), respectively in CLL patient group. All controls were negative with an exception of two patients were LMP1 positive. Enzyme linked immunosorbent assay test (ELISA) was used to detect the level of IL - 8 and IL - 10 in serum of newly diagnosed of CLL patients. Interleukin 8 was significantly higher in CLL cases group (33.1 pg/ml) compared to control group.On the other hand It was found that high increase in IL - 10 level ,in CLL patients when compared with controls. Conclusion : It can be concluded that there is a significant relationship between EBV and Chronic lymphocytic leukemia, mainly EBERs, also the association of significant increase in IL - 10 and IL - 8 with CLL.

Abstract: الزوائف الزنجارية : وهي بكتريا سالبة لصيغة الكرام والمنتشرة بشكل واسع في البيئة مثل التربة والمياه. وهذه البكتريا تتسبب في كثير من الالتهابات مثل التهاب المجاري البولية والتهاب الحروق وهي بكتريا انتهازية. وتشكل تهديد لحياة المصابين بالمجاري البولية وخاص | Pseudomonas aeruginosa is a Gram |( - ve) bacteria, widely presents in the environment such as soil, water, its incubation period (1 - 3) days, generation time 1 - 2 hrs. This bacteria causes many infections such as (UTI), and burn infections. It is an opportunistic pathogen, life threating for immune compromised patients such as diabetic patients. Pseudomonas aeruginosa is a nosocomial pathogen, and it is ranking the second among Gram ( - ve) hospitals acquiring pathogen. Its antibiotic resistance increased due to acquiring many antibiotics resistance genes. The spread of these genes among bacteria is via plasmids. Plasmid profiling of Ps. aeruginosa isolates by gel electrophoresis is a best technique for detection of plasmid content. Through this study, which was carried out in two main teaching hospitals, the diabetic center and private labs in Baghdad, during the period from January to October 2014. A total of (620) urine specimens were collected during (9) months. Urine specimens from inpatients were (420 / 620, 67.75%) and from out patients were (200 / 620, 32.25%). Urine specimens from Dialysis unit were (280 / 620, 45.1%) and from burn units were (140 / 620, 22.5%). The male represented (n = 334, 52.38%) while female were (n = 286, 46.20%). The positive cultures of urine samples obtained from hospitalized patients were (72 / 420, 17.1%) while for urine samples obtained from out patients (n = 40 / 200, 20%) were positive culture. A total of (112) positive culture out of (620) collected with (18.06%) percentage. A total of (30) bacterial isolates were tested by using disc diffusion method for susceptibility test forward to (15) antibiotics. Ps. aeruginosa isolates showed highest resistance to gentamicin (87.5%) while the lowest resistant toward meropenem, and imipenem with resistance percentage (16.7% and 8.0%) respectively.The occurrence of multi - drug resistance in (30) selected isolates were grouped as follows to (MDR) for those isolates which showed resistance to at least (3) antibiotics which was found to be (5 / 30, 6.6%). While (XDR) referred to those isolates which showed resistance to (4 - 5) antibiotics with (19 / 30, 63.3%). In related to (PDR) which referred to isolates that showed resistance to more than 5 with (6 / 30, 20%). The extracted plasmid DNA were resolved by gel electrophoresis for detection of plasmid content for (20) isolates including (10) isolates from inpatients, and (10) isolates from out patients. The selection of these isolates were grouped according to their antibiotic resistance pattern and the number of plasmids that they carried. The results showed that out of (20) there were (12 / 20, 60%) had no plasmid. While the remaining (8 / 20, 40%) had plasmids with different sizes and numbers. By using PCR technique the most common kinds of genes such as bla CTX - M, bla OXA, which encoded extended spectrum ? - lactamase (ESBLS) and those for metallo ? - lactamase such as bla IMP, were investigated with specific primers. Five isolates were selected depending on the numbers of plasmids which they carried and their resistance to antibiotics.

Abstract: Diabetic Nephropathy (DN) is a common complication of diabetic diseases occuring all over the world including Iraq. This type of microvascular complication of diabetes mellitus represents the most common reason of end stage renal disease (ESRD) in the world which considers the main reason for hemodialysis, kidney transplantation and death in developed countries. For this reason the assessment of some biomarkers as an early predicator before onset of microalbuminuria stage of diabetic nephropathy and the correlations between these biomarkers with microalbuminuria were carried out.This study was achieved at AL - Yarmouk Teaching Hospital and the Diabetes National Center /AL - Mustansiriyah University/Baghdad from January 2013 to September 2014. The study involved ninety individuals, twenty volunteers selected from the local community; apparently healthy (group I), 40 type 2 diabetics with normal urinary albumin to creatinine ratio (UACR) (<30 mg/g) (group II), and 30 type 2 diabetic patients with abnormal UACR (? 30 - 300 mg/g) (group III). Mean of diabetes duration (D.D.) in group II is about 4 years and in group III is about 8 years. The mean age for group I, II and III were 53, 55 and 58 years respectively. The concentration was measured of each microalbuminuria by turbidmeteric method, estimated glomerular filtration rate (eGFR) by using chronic kidney diseases - epidemiology equation, glycated heamoglobin (HbA1c) by using high performance liquid chromatography (HPLC), both fasting blood sugar (FBS) and creatinine (serum and urine) by using colorimeteric method, body weight by using body mass index (BMI) and all of IL - 18, IL - 12 IL - 4, IFN - ? and urinary vitamin binding protein (VDBP) by using ELISA method in three groups.The present study showed that there is inverse correlation between UACR and eGFR. The cause of this inverse correlation is that the decline in renal function of diabetics can be predicted accurately by using both UACR to show the increase in microalbuminuria while eGFR show a measure of the decrease in the ability of kidney for filtration.The difference of FBS mean between group I and II and group I and III was significant (P= 0.000 for both). The P - value between II and III groups was significant (P= 0.024). The difference of HbA1c mean between group I and II, group I and III and group II and III was significant (P=0. 000 for all). These results were expected as high HbA1c level is in consequence of high FBS. The difference of BMI mean between group I and II, group I and III and group II and III was not significant (P= 0.870, 0.885 and 0.968 respectively). Because the BMI levels were approximately constant in three groups. The difference of D.D. between group II and III was significant (P= 0.000).There was no significant correlation in group II between urinary albumin to creatinine ratio with each of diabetic duration, glycated haemoglobin, fasting blood sugar and body mass index (r=0.219 with P=0.244, r=0.039 with P=0.840, r=0.080 with P=0.673 and r= - 0.126 with P= 0.506 respectively); but there was positively significant correlation between urinary albumin to creatinine ratio with each diabetic duration, HbA1c and fasting blood sugar in group III (r=0.298 with P=0.043, r=0.869 with P=0.000 and r=0.518 with P=0.003 respectively) which may be due to the chronic nature of the disease in this group that require these risk factors to initiation; however, the correlation was non significant between UACR and BMI (r= - 0.127 with P=0.228) in group III.The difference of S.Cr. among I and II groups, I and III groups and II and III groups were not significant (P= 0.998, P= 0.331 and P= 0.145 respectively).The correlation was not significant in group II between serum creatinine with each of diabetic duration, glycated haemoglobin, fasting blood sugar and body mass index (r= - 0.140 with P=0.462, r= - 0.124 with P=0.515, r=0.168 with P=0.374 and r=0.007 with P= 0.969 respectively). Also, there was no significant correlation in group III between S. Cr. with each D.D., HbA1c, FBS and BMI (r=0.187 with P=0.077, r=0.109 with P=0.220 and r=0.175 with P=0.124 respectively). The reason of these results backs to that S. Cr. level is not increased as the podocytes remain intact in the diabetics with and without microalbuminuria.The difference of eGFR between group I and II was not significant (P= 0.303). The difference between group I and III and group II and III was significant (P= 0.001 and 0.010 respectively). The correlation was not significant in group II between eGFR with each of diabetic duration, glycated haemoglobin, fasting blood sugar and body mass index (r=0.121 with P=0.524, r= - 0.180 with P=0.341, r= - 0.310 with P=0.096 and r=0.021 with P= 0.911 respectively). Also, there was no a significant correlation in group III between eGFR with each diabetic duration, HbA1c, FBS and BMI (r= - 0.179 with P=0.07, r= - 0.188 with P=0.061, r= - 0.123 with P=0.388 and r= - 0.112 with P=0.557 respectively). The reason of these results back to that eGFR level is at the normal range in group II and slightly beneath the normal range in group III in consequence of the podocytes remain intact in the diabetics with and without microalbuminuria.The difference of urinary VDBP level between group I and II, group I and III and group II and III was significant (P= 0.000 for all). The correlation between urinary albumin to creatinine ratio levels and VDBP level (r=0.963) with P - value 0.000 which was positively significant in group III. The correlationbetween eGFR and VDBP was - 0.524 with P - value 0.003 which is inversely significant in group III. The reason of this inverse correlation may be similar to the reason of inverse correlation between eGFR and UACR, as the cubilin - megalin receptors are common receptors for albumin and vitamin D binding protein. Otherwise, the correlation between urinary VDBP and eGFR in the group I was a weak negative with non significant P - value (r= - 0.188, P=0. 428). The reason of this non significant correlation is that the cubilin - megalin receptors are not damaged by inflammatory process to elevate VDBP in urine; also the podocytes in glomeruli are intact from the damage by inflammatory process, so the eGFR was at the normal range in the control group.The correlation was a positive between HbA1c and VDBP levels in group II and group III (r=0.579, P=0. 001 and r=0.686, P=0.000 respectively). This positive correlation was explained on the basis that deterioration of sugar level control lead to increase the proinflammatory cytokines that damage cubilin - megalin receptors then VDBP increase in urine.The difference of serum IL - 18 level between group I and II, group I and III and group II and III was significant (P=0.000 for all).The correlation between urinary albumin to creatinine ratio and IL - 18 was 0.983 with P - value 0.000 which was positively significant in group III. This may back to damage the cubilin - megalin receptors by IL - 18 action that lead to increase of UACR in urine. In other words, the correlation between serum creatinine and serum IL - 18 in group III was not significant (r=0.041 with P= 0.830). This may back to that podocytes remain intact in this early stage of diabetic nephropathy. There is a significant positive correlation between serum IL - 18 levels and HbA1c levels in group II and group III (r=0.641, P=0.000 and r=0.721, P=0.000 respectively). These two positive correlations support the suggestion of choosing serum IL - 18 as an excellent biomarker for avoidance an early stage of the disease.The difference of IFN - ? levels between group I and group II, between group I and group III and between group II and group III were not significant as follows : (P=0.640, P=0.292 and P=0.522 respectively). The correlation between UACR and IFN - ? (r=0.047) with P - value 0.830 which was not significant in group III which means that IFN - ? is not a good biomarker for prediction of the microalbuminuria as an early stage of DN.The difference of IL - 12 level between group I and group II, between group I and group III and between group II and group III were not significant (0.884, 0.431 and 0.439) respectively. The correlation between UACR and IL - 12 (r=0.190) with P - value 0.314 which was not significant in group III.The difference of IL - 4 levels between group I and group II, between group I and group III and between group II and group III were not significant (0.943, 0.704 and 0.648 respectively). The correlation between UACR and IL - 4 (r=0.169) with P - value 0.371 which was not significant in group III.These results of IFN - ?, IL - 12 and IL - 4 might lead to conclude that both cytokines can’t be selected as a biomarker for an early detection of DN. Finally from the all presented data it can be concluded that IL - 18 and VDBP are considered more sensitive and more efficient than a classic diagnostic method (UACR and eGFR) for avoidance and detection the early stage of DN.

Abstract: تعتبر اصابة الكبد الحاد احد الامراض ذو الاعراض السريرية التي تتصف بارتشاح الخلايا اللمفية الى الكبد وتجمع السوائل وارتفاع انزايمات الكبد مثل ناقل امين الاسبارتات Aspartate aminotransferase(AST) في مصل الدم. هنالك الكثير من الاسباب التي تؤدي الى حدوث ضرر | Acute Liver Injury is a vital clinical syndrome characterized by infiltration of lymphocytes in the liver, fluid accumulation, and elevation of liver enzymes such as Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the serum. There are many causes of liver injury, but in this particular study Staphylococcal Enterotoxin B (SEB) was used to induce acute liver injury in mice, it is previously known that (SEB) it act as superantigen that bind with T cell receptor variable region beta chain (VB8), and MHC II of Antigen Presenting Cells (APCs), which leads to activation of T - cells, and huge secretion of pro - inflammatory cytokines, all of these events cause an acute liver injury lead to liver failure, and death. In the last few decades the importance of some natural products appeared, in which these botanicals have an anti - inflammatory properties. Resveratrol is one of these botanicals with an anti - inflammatory effects, which was used as treatment in this study.This study was particularly intended to study the influence of Resveratrol on acute liver injury induced by Staphylococcus Enterotoxin B, lead to liver failure which includes estimation of aspartate aminotransferase levels (AST), histopathological analysis, immune cell counts of liver and spleen, in addition, study whether resveratrol has the ability to cause immunological changes on different immune cells that lead to suppress acute liver injury by using flowcytometry technique,these cells are inflammatory cells carrying CD3+ T cells, CD4+ T cells, CD8+ T cells, NK1.1+ T cells, CD44+ T cells, and suppressive cells such as Myeloid Derived Suppressor Cells (MDSCs), T regulatory cell (FOXP3), as anit - inflammatory markers. Furthermore evaluate the pro - inflammatory, and anti - inflammatory cytokines by using Bio - plex. Also to determine the molecular mechanism in which resveratrol can lead to induce changes in microRNAs (miRNAs) by microarray analysis. Finally validation (miRNAs) resulting from microarray analysis and genes of interest associated with these miRNAs by Real time polymearase chain reaction (RT - PCR).After sixteen hours blood samples were collected to determine AST levels in differents groups using Nanodrop, (Fisher - USA), after sixty hours animals sacrificing organs (liver, spleen) were collected afterward liver samples in 10% formalin were sent for histopathological study, liver immune cells were isolated for counts and molecular study (microarray analysis and quantitive (RT - PCR) total RNA was isolated from liver immune cells for microarray analysis then preparation of complementary Deoxyribonucleic acid (cDNA) by Reverse transcriptase PCR. Validation of the microarray analysis data was achieved by Real time PCR. Spleen immune cells were collected afterward for flowcytometric analysis of CD3+, CD4+, CD8+, NK1.1+, CD44+ T cells, MDSCs, and T regulatory cells using cell surface staining and intra cellular staining.This study showed that Resveratrol oppose the effect of SEB induced acute liver injury through decrease AST concentrations (P< 0.0001). Also Resveratrol 50mg/Kg body weight led to cause reduction in the size of the spleen, compared to SEB+ Vehicle group. Histopathology study reported that resveratrol led to decrease of hepatic necrosis up to 10% in comparison to vehicle group with 60% of hepatic necrosis and decrease in the inflammatory response represented by immune cells as in liver immune cell counts which showed a significant decrease (P< 0.014) after 50mg/ Kg body weight of Resveratrol treatment. Spleen immune cell counts result reported a significant decrease (P<0.013) in the total cells when Resveratrol was used as treatment compared to disease group. Regarding to Flowcytometric analysis, it was found that Resveratrol significantly decrease the absolute count of CD3+, CD4+, CD8+, NK1.1+, CD44+, Foxp3+ T cells in C57BL/6 mice (P< 0.0019, P< 0.001, P< 0.009, P< 0.002, P< 0.03, and P< 0.03 respectively). While MDSCs result reported significant increase with P< 0.01 in absolute cell counts after Resveratrol treatment. Depending on the Bio - plex data showed significant decrease in serum concentrations of inflammatory cytokines IL - 1?, IL - 1?, IL - 3, IL - 5, IL - 12p(40), IL - 12p(70), IL - 13, IFN?, MIP - 1?, MIP - 1?, KC and Rantes cytokines with significant P values (0.009, 0.004, 0.034, 0.004, 0.0009, 0.01, 0.0007, 0.009, 0.0037, 0.0001, 0.0035, 0.006 respectively), while anti - inflammatory cytokines IL - 6, IL - 10 and G - CSF c showed a significant increase in the serum concentration after Resveratrol treatment with a P values of, 0.012, 0.02 and 0.001 respectively. Microarray analysis results recognized 451 miRNAs with P< 0.05, according to fold change expression, 78 miRNAs have fold change greater than - 1.5 fold of expression in Resveratrol treatment group (downregulated), while 87 miRNAs have fold change greater than 1.5 fold of expression (upregulated). According to the ingenuity tools predicted target gene for some of these miRNAs by using miRNA.org database, the database showed that miR - 130a - 3p with - 2.28 fold expression have direct relation of binding with CSF1 gene, Real time PCR results confirmed the results obtained from microarray analysis, the result of miR - 130a - 3p showed a significant decrease of relative fold expression with P< 0.013, and Colony Stimulating Factor - 1 CSF1 (M - CSF) relative expression increased significantly after resveratrol treatment with P< 0.0001. From all of previous data, it can be concluded that Resveratrol can counteract acute liver injury induced by SEB, by decrease AST concentration. Resveratrol acts as an anti - inflammatory compound due to decrease of immune cell numbers, decrease of inflammatory markers, and increase of anti - inflammatory markers. miR - 130a - 3p with inflammatory properties downregulated after resveratrol treatment. Finally Resveratrol treatment increased relative fold expression of CSF1(M - CSF); gene which play a role in the MDSCs proliferation

Abstract: التهاب المفاصل الرثوي هو احد امراض المناعة الذاتية الاكثر شيوعا والذي يتميز بالتهاب المفاصل المزمن والذي يؤدي فيما بعد الى تدمير المفاصل.لا يزال مرض التهاب المفاصل الرثوي يعرف على انه سمة من التوسع في الغشاء الزليلي وارتشاح الخلايا الالتهابية اضافة الى | Rheumatoid arthritis (RA) is one of the most common systemic autoimmune diseases characterized by chronic joint inflammation and subsequent joint destruction. It is well known that RA is characterized by the expansion of the synovium and infiltration of the inflammatory cells coupled with destruction of adjacent articular cartilage and bone. This is strongly dependent on CD4 T cell. CD4 Cells stimulate monocytes, macrophages, synovial fibroblasts, and other cells to produce cytokines such as tumor necrosis factor - ? (TNF - ?), interleukin - 1 (IL - 1), IL - 6, IL - 15, IL - 17 and metalloproteinases that produce tissue damage. TNF is a major inflammatory cytokine contributing to the pathogenesis of RA, which provides rational for development of anti - TNF biological agents in the treatment of RA.Wnt pathway (a complex protein network) important in control of the bone formation through the regulation of osteoblast activity, and sclerostin is an important in the regulator of the Wnt pathway by blocking Wnt binding to its receptor and thereby inhibiting bone formation. Blockage of Wnt antagonists such as sclerostin will trigger repair or even healing of bone erosion.Recently have shown that IL - 1Ra has been given therapeutically in several experimental models of arthritis with weak effect in RA. This study planned to evaluate the frequencies of CD4+CD25+ Treg cells in Iraqi patients treated with RA under treatment with biological therapy (Etanercept). The level of serum sclerostin, serum level of IL - 1RA, and investigate the correlation between serum sclerostin and Treg expression. Correlate the level of serum sclerostin and Treg expression with disease activity by (CDAI or DAS28).This study was performed during the period from January 2016 to May 2016.The patients were attending the out patients' Clinic in Medical City/Baghdad Teaching hospital/Rheumatology Unit and the laboratory Enzyme Linked Immunosorbent Assay tests were done in Bio - technology center at the University of Al Nahrain, flow cytometery analysis was performed in the private laboratory (Al Rawabi Laboratory) at Yarmouk/Baghdad. Thirty patients and 30 apparently healthy control individuals were included in this study, Patients under treatment of etanercept.The diagnosis of RA patients has performed under the rheumatologist consultant at the consultation clinic of Baghdad Teaching Hospital of the medical city. Blood samples had taken from RA patients to measure Erythrocyte Sedimentation Rate, Complete Blood Picture, Rheumatoid Factor and High - Density Lipoprotein. Also, analyze the serum levels of Anti - Citrullinated Protein Antibodies and estimate the levels of sclerostin and IL - 1RAin patients and healthy individuals using Enzyme Linked Immunosorbent Assay test kits. CD4+CD25+ Treg cells had achieved by flow cytometery analysis.The results showed the reduction in Treg cells in patients (0.00264 ± 0.002) % under biological therapy than control group (0.026 ± 0.012) % with significant difference (p< 0.05). Also body mass index showed significant difference between patients (32.10 ± 5.81) kg/m2 and control group (28.84 ± 4.67) kg/m2 (p< 0.05). The results showed that sclerostin level higher in healthy (1.072 ± 0.59) ng/ml than patients (0.801 ± 0.28) ng/ml which showed significant difference (p<0.05). Furthermore IL - 1RA serum level was higher in healthy (0.979 ± 0.34) ng/L than patients (0.633 ± 0.35) ng/L with significant difference (p<0.05). Anti - Cyclic Citrullinated Peptide results showed non - significant difference between patients and healthy control. Treg cells is reduction in the patients with RA. Sclerostin and IL - 1RA levels are low in patients treated with etanercept.

Abstract: اعتلال الكلية السكري هو السبب الرئيسي للمرض الكلوي المزمن وويرتبط ذلك مع زيادة وفيات مرضى القلب والاوعية الدموية. التعريف الكلاسيكي لاعتلال الكلية السكري هو زيادة افراز البروتين في البول. وتتميز المرحلة المبكرة للمرض عن طريق زيادة صغيرة في افراز الزلا | Diabetic nephropathy (DN) is the leading cause of chronic renal disease. It is associated with increased cardiovascular mortality. The DN has been classically defined as increased protein excretion in urine. Early stage is characterized by a small increase in urinary albumin excretion (UAE), also called microalbuminuria or incipient DN. More advanced disease is defined by the presence of macroalbuminuria or proteinuria. The latter is classically named overt DN.This study was planned with the aim of evaluate the levels of urinary Monocyte Chemoattractant Protein - 1(MCP - 1), interleukin (IL - 18), Osteopontin and Nephrin at diabetic nephropathy and its correlation with the parameters in Iraqi type 2 diabetic subjects and to explore the impact of albuminuria and duration of the diabetes on fine glomerular architecture using podocyte injury related marker (Nephrin) in urine. This may explore the more specific, and sensitive early biomarkers for nephropathy in diabetic patients and could help the physicians in controlling the occurrence of renal failure.Sixty Iraqi type 2 diabetes mellitus patients attending the National Diabetes Center for Treatment and Research at Al - Mustansiriyah University during the period October 2014 - June 2017 were recruited for this study. For the purpose of comparison, 20 control subjects matched for age, gender and ethnic background were also included. The patients and controls were characterized in family history of diabetes, diabetic nephropathy groups divide by used Albumin to creatinine ratio. The patients were also assessed for duration of disease, fasting serum glucose, and serum creatinine and blood urea.The mean urinary level of MCP - 1 (15.38±15.50 vs. 6.10±7.23pg/ml) and IL - 18 (35.90±16.67 vs. 23.55±12.67pg/ml) and osteopontin (337.15±257.06 vs. 174.11±183.65ng/ml) and nephrin (100.01±88.66 vs. 52.23±19.61ng/ml) were significantly higher in T2DM patients as compared to controls.The mean levels of urinary MCP - 1, uIL - 18 and osteopontin in macroalbuminurea group of patients were significantly higher than those in normoalbumine ( p < 0.008, p< 0.0001 and p< 0.03 respectively), and only of the Nephrin in the normoalbuminurea group of patients showed significant increased level as compared to the controls (52.23±19.61 vs.75.05±37.8 ng/ml) (p<0.022).The duration of disease showed an increase in mean of urinary level for all the markers MCP - 1, IL - 18, osteopontin and nephrin (17.01±18.09 vs. 19.76±21.30 pg/ml, 29.24±15.98 vs. 42.98±17.25pg/ml, 321.1±291.05 vs. 409.05±210.0ng/ml, 99.40±48.40 vs. 79.21±44.23 ng/ml) respectively, in late duration of disease as compared with early duration of disease except in Nephrin showed the early duration of disease higher than the late duration of disease (99.40±48.40 vs. 79.21±44.23), although the differences were not significant.The Receiver operating characteristic (ROC) curve analysis for all markers MCP - 1, IL - 18, Osteopontin and Nephrin levels (MCP - 1 = 0.72, IL - 18 = 0.71, Osteopontin =0.70 and Nephrin =0.72) for early diagnosis and detection of DN revealed that the cut - off value of uMCP - 1 was 6.23 pg/mg with 70% sensitivity and 75% specificity; whereas, the cut - off value of u IL - 18 pg/ml was 23.69 ng/mg with 80% sensitivity and 59% specificity and Nephrin was 49.5 ng/ml with 78% sensitivity and 55% specificity. uOsteopontin was 182 ng /ml with 68% sensitivity and 69% specificity.The linear correlation revealed a significant positive linear correlation between urinary MCP - 1, IL - 18, Nephrin and A : C ratio, also showed a significant negative linear correlation between urinary MCP - 1, IL - 18, osteopontin and GFR.In conclusion the Nephrin may be considered as potential diagnostic and prognostic biomarker a for the early detection and progression of diabetic nephropathy while the uMCP - 1, uIL - 18 and uOsteopontine may be considered as potential prognostic biomarkers for the diabetic nephropathy. The duration of disease also affect investigated biomarkers suggesting the long term effect of hyperglycemia

Abstract: التهاب العظام والمفاصل Osteoarthrosis)) او فصال العظام او ما يعرف بالاسم الشائع السوفان هو مرض يحدث في غضروف المفصل الذي يعمل على عدم احتكاك عظام المفصل ,مما يؤدي الى تقليل هذه الحماية ضد الاحتكاك فتصبح حركة المفصل بها خشونة ومصحوبة بالالام عند استخدام ا | Osteoarthrosis (OA) are defined as a progressive architecture destruction of the joints compared to slow healing of these joints which leads to reduce protection against degeneration and the movement of the joint is associated with by the roughness and accompanied by pain when using the joint. Often this disease affect the knee joint, it may affect any other joint in the body, especially those that carry weights such as leg hinges the pelvis, elbow and spine. The aim of this study is to evaluate the efficacy of platelets - rich plasma injection in osteoarthritis knee and the estimation of the biological and immunological markers associated with the treatment. This study involved 50 patients suffering from inflammation of the knee joint under supervision of speiclist of orthopedic ,most of these patients attended Al - Shaheed Firooz hospital in wasit Governorate and specialty private clinics of orthopedic and Rheumatology in the district during the period from April 2015 until October 2015.The age of patients was about 35 - 65 years; 31 females and 19 males with 25 healthy matching group. All patients were injected into the knee joint by a specialist physician with two injections during two months with platelets - rich plasma (PRP)after its preparation from the same patient's blood in sterile conditions. This was done after the signing of the patient or one of his relatives on the written consent to conduct the injection process after explaining and clarifying the principle of injection and the purpose. The level of pain of patients group was measured by Visual Analogue Scale (VAS). The enzyme linked immunnosorbant assay ELISA method to determine the level of some of cytokines in serum of patients group (interleukin - 1beta, tumor necrosis factor - alpha,IL - 10,IL - 8 and Transforming growth factor - B1) in addition to measuring the concentration of C - Reactive protein (CRP).The rate of Erythrocyte Sedimentation Rate (ESR) was also estimated. All were done to all patients groups before and after injections with PRP in addition to healthy group. Statistical analysis showed no significant differences between males and females (54.5±1.2 males, 53.2±2.1 females). The study showed significant decrease in the mean of the Visual Analogue Scale (VAS) of patients before and after two months of injections with (PRP) 8.46 ± 0.104, 5.98 ± 0.129, , respectively, with highly significant differences (P=000.0) , also the study showed that there was no significant differences in VAS between age groups (30?s, 40?s, 50?s , 60?s) before and after injections with PRP (7.5,8.0 ,8.38 ,9.05), (5.0,5.55,5.69,6.7) respectively. The study also showed a difference in the mean for inflammatory marker C. Reactive protein concentration before and after injections with PRP 7.156± 0.328 µg/ml, 5.384± 0.196 respectively, in comparison with healthy group with highly significant differences (P=0.000).The study also showed a difference in the mean of ESR before and after injections with PRP (35.66± 0.879 mm/1hr, 23.7±0.856) respectively, with in comparison with healthy group highly significant differences (P=0.000).The mean of Interleukin 1 - Beta(IL - 1?) was decline after injections with PRP from 13.220±0.295, pg/ml to 9.622 ± 0.273 pg/ml in comparison with healthy group with highly significant differences (P=0.000). Also a decline in the mean of Tumor necrosis factor - alpha (TNF - ?) after injections with PRP from 62.384±0.927 pg/ml to 55.36 ± 1.121 pg/ml in comparison with healthy group with highly significant differences (P=0.000). The study also demonstrates a decrease in the mean of Interleukin - 8 (IL - 8) before and after injections with PRP (41.092±0.808 pg/ml, 35.93 ± 0.813pg/ml) respectively in comparison with healthy group with highly significant differences (P=0.000). An increase in the mean of Interleukin - 10(IL - 10) after injections with PRP from 5.108±0.291 pg/ml to 6.734±0.330pg/ml, in comparison with healthy group with highly significant differences (P=0.000). The final parameter in this study was demonstrated an increase in the mean of Transforming growth factor - ?1 (TGF - ?1) before and after injections with PRP (111.544±6.960, 149.212±7.540pg/ml) respectively in comparison with healthy group with highly significant differences (P=0.000). Association was obtained between VAS score and C. RP as well as ESR after treatment. PRP treatment also has an impact on increasing the level of anti - inflammatory IL - 10 and TGF - ?1 on one side and the decreasing level of pro - inflammatory IL - 1?, TNF - ?,IL - 8 (catabolic marker) on the other side these results suggest the inhibition of catabolic process demonstrated by reducing of VAS scores and the efficacy of effectiveness plasma rich platelets (PRP) treatment of osteoarthrosis.

Abstract: Prostate cancer is the most common malignancy and the second leading cause of cancer related death among males worldwide. Prostate cancer developed in prostate , a gland that is located below the bladder and just in front of rectum.Inflammation is a fundamental physiological process that can arise in any tissue in response to traumatic, infectiousor autoimmune injury. Transforming growth factor beta one (TGF - ?I) is a potential regulator of prostate cancer cell growth that signals through a heteromeric complex composed of type I and type II receptors.TGF - ?R II is an important receptor , because TGF - ? bind to receptor II to initiate it's signaling, then receptor II recruits receptor I to initiate signal transduction. Interleukin - 17 (IL - 17) is a pro - inflammatory cytokine produced by T - helper 17 (Th17) cells contributes toboth the processes by playing a dual role in the antitumor immunity. On one hand, IL - 17 encourages an antitumor cytotoxic T cell response leading to tumor regression. On the other hand, by promoting angiogenesis and egress of tumor cells from the primary focus, so IL - 17 promotes tumor growth.This study was carried out to establish the correlation between expression of Transforming growth factor beta one(TGF - ?I), Transforming growth factor beta receptor one (TGF - ?RI) and Transforming growth factor beta receptor two (TGF - ?RII) and prostate cancer progression. Also to establish the role of IL - 17 in prostate cancer development.The study consisted of 16 patients with poorly differentiated malignancy (PDM) ,whose age ranged (48 - 89) years, with mean age of (71.2) years , and 25 patients with moderately differentiated malignancy(MDM) , whose age ranged (31 - 83) years , with mean age of (66.6) years , and 46 patients with benign prostatic hyperplasia (BPH) , whose age ranged (27 - 85) years , with mean age of (64.3) years. Allpatients were diagnosed surgically by consultant physicians in Baghdad hospital for specialist surgeries , Al - Yarmook teaching hospital ,as well as AL - Hilla teaching hospital , and 20 normal tissue sample taken from cadaver, whose age ranged (17 - 28) years , with mean age of (21.8) years , where chosen as a control group. The work was conducted in Iraqi center for cancer and medical genetic researches. The study were performed during the period from March 2014 to December 2014).Immunohistochemistry (IHC) technique was used to detect the level of expression of TGF - ?I , TGF - ?RI , TGF - ?RII and IL - 17 protein in tissues of patients and healthy control groups.The current study revealed that there was significant difference in mean levels of TGF - ?I protein expression between each of poorly and moderately differentiated malignancy compared with healthy control subjects with P - value of 0.001 , but there was no significant difference in mean level of TGF - ?Iprotein expression between benign prostatic hyperplasia and healthy control subjects with P - value of 0.398. Also there was no significant difference between poorly and moderately differentiated malignancy in mean level of TGF - ?I protein expression.TGF - ?R1 protein was expressed in 3 (18.7%) and 14 (56%) of poorly and moderately differentiated malignancy respectively , with weak immunostaining reaction was the most frequent score. There was significant difference in mean level of TGF - ?RI protein expression among all studied groups. TGF - ?RII protein was expressed in 6 (37.5%) and 22 (88%) of poorly and moderately differentiated malignancy respectively ,with weak immunostaining reaction was the most frequent score. There was significant difference in mean level of TGF - ?RII protein expression among all studied groups.IL - 17 immunohistochemical expression was detected in tissues of all studied groups , the results showed that moderate immunostaining reaction was the most frequent score among them. There was significant difference in mean levels of IL - 17 protein expression among all studied groups.We concluded that there was statistically significant association between the loss ofexpression of TGF - ?1 signaling receptors, especially TGF - ?RI, andincreasing grades of malignancy in prostate cancer. These resultssuggest a potential mechanism for prostate cancer cells toescape the growth inhibitory effect of TGF - ? and thus, leadingto a more malignant phenotype.

Abstract: تعتبر عزلات جراثيم التدرن المقاومه للادوية من المشاكل الرئيسية في معالجة مرضى التدرن حول العالم. , ولاهميته اجريت هذه الدراسة لتسليط الضوء اكثر حول الحساسيه الدوائية بواسطة الطرق المختبرية التقليدية وعلى الوسط الصلب ومقارنته مع الطرق التشخيصية المختبرية ا | Drug resistant tuberculosis remained as major problems in the treatment of tuberculosis patients in the world. A prospective study was conducted to evaluate drug susceptibility testing (DST) by classical methods on solid media as compared with advance and molecular Laboratory diagnostic methods (Bactec MGIT 960 and GeneXpert MTB - RIF ). The study included the estimation of the first line anti - TB drugs, including (Rifampicin,Isonizid,Streptomycin and Etambutol) by solid media (Lowenstein - Jensen medium) and Bactec MGIT 960 system. In addition, the use of rapid molecular diagnostic method by GeneXpert MTB/RIF assay. Seventy five TB patients attending the National Reference Laboratory of Tuberculosis /medical city - Baghdad from December 2015 to June 2016 were included in this study. Patients were classified into two main groups : selected MDR patients, which were referred from different hospitals and health respiratory center in Iraq, represented 46 in order to compare different laboratory methods to detect of DST isolates, while 29 were randomly isolated and identified , the study matched by age and gender were also included. This study revealed that the drug resistance tuberculosis to Rifampicin was 47 (62.7%), Isonizid 41 (54.7%), Streptomycin 42 (56.0%) and Ethambutol 38 (50.7%). Respectively , on the golden stander in which solid media were used.The molecular and advance technique (GeneXpert and Bactec MGIT 960) as applied to estimation of drug resistance tuberculosis, the results of drug susceptibility testing (DST), as showed highly sensitivity and Accuracy, when compared with golden stander( LJ media) especially in detected of primary drugs (Rifampicin and Isoniazid) and showed lower sensitivity and accuracy to detected of the secondary drugs (Streptomycin and Ethambutol). The Multiple drug resistance (MDR - TB) case from selective samples was found to be almost similar to that found in other countries of the middle east and other regions in the world. While in the randomly identified samples, the rate of MDR - TB was lower than the referred (previously treated) cases.The GeneXpert MTB - RIF system is rapid molecular methods that used in many countries to identify of MTB and Rifampicin detected during 2 hours only, that used in this study. The high Rifampicin resistance and other drugs of local isolates could be due to abuse of the drug,defaulter and relapse of retreating cases (previously treated).

The samples were analyzed for any signs of infection and immediately inoculated on blood and MacConkey agar media plates. All plates were incubated aerobically at 37 ?C for 24 - 48 hrs.Results of morphological and biochemical characterization revealed that out of total of 120 urine samples, 110 showed positive culture, among them 37 isolates are belonged to coagulase - negative Staphylococci, other 73 isolates belonged to other bacterial genera.Molecular detection of coagulase gene (coa) was done for all CoNS isolates. The results showed that 28/37 isolates (75.67%) were positive for this marker, distributed as follows : S. epidermidis gave 15 isolates, S. saprophyticus gave 9 isolates and S. haemolyticus gave 4 isolates.Also, molecular investigation of fnb A and B genes are carried out for all CoNS isolates by using specific PCR markers. 13/37 isolates (35%) were positive for fnb A gene, as 6/13 of S. epidermidis, 5/13 of S.saprophyticus and 2/13 of S. haemolyticus have this gene in their genome. On the other hand, only 4/37 isolates gave positive result for fnb B gene; as 2 isolates of both S. saprophyticus and S. epidermidis have this gene in their genome.Moreover, sec gene also was investigated in CoNS isolates. The results showed that all CoNS isolates are free from this gene.Regarding urease enzyme production, S. epidermidis and S.saprophyticus isolates were found to be urease positive, while S.haemolyticus isolates display urease negative.To demonstrate the ability of bacteria to form struvite stone, urine samples obtained from healthy individuals were used. It was found that struvite stone was formed by S. epidermidis and S. saprophyticus isolates.Moreover, susceptibility to 10 antibiotics were tested by using disc diffusion test (DDT). S. epidermidis was showed 100% resistance for each Methicilline, Ceftriaxone, Ceftazidime and Cefoxitin. Also, it show high resistance 94%, 88%, 88%, 76%, and 59% for Impenem, Gentamycin, Pipracillin, Ciprofloxacin and Amikacin respectively. However, S. epidermidis showed low resistance (6%) for Vancomycin. So, all S. saprophyticus isolates showed high resistance (100%) to each Pipracilline, Ceftriaxone, Methicillin, Ceftazidime and Ciprofloxacin. It showed high resistance (92%) for each Vancomycin and Imipenem, and (83%), (75%), (75%) for Cefoxitin, Gentamycin and Amikacin respectively.

Abstract: This study aimed to investigate the bacterial profile of surface and core of infected tonsils and adenoid tissues and histopathological examination of these organs.A total of 122 samples represented by 63 excised tonsils and 59 excised adenoids in addition to 57 blood samples were collected from 70 patients who were referred to Hilla Teaching Hospital (Ear, Nose and Throat unit) in Hilla city within a period of four months from November 2015 to February 2016. Those patients weresuffering from chronic tonsillitis and adenoid hypertrophy. The ages of those patients ranged from 2 to 15 years, 41 (59%) of them were males and 29 (41%) were females.The study included three main parts. The first one was the bacterial diagnosis based on relied diagnostic procedures. Second part was the detection of antistreptolysin O (ASO) by using latex agglutination test, while the third part included histopathological study to detect the pathological lesions that occur during these infections.The results indicated that, the most age group being susceptible for chronic tonsillitis and adenoid hypertrophy was the group of 7 - 10 years, represented 33 patients with a percentage of (47%). Among this group, males were more susceptible with percentage of 20 (29%) compared to female patients13 (19%).The surface of all samples (tonsil and adenoid) revealed positive results for bacterial culture, while in the core of tonsil only 44 samples (70%) were positive for bacterial culture while 19 samples (30%) were negative results (no growth). As in tonsils, the core of adenoid revealed positive results in 32 (54%) samples, while 27 (46%) samples were negative results.The suspected isolates were fully identified by using bacteriological, biochemical and Vitek 2 techniques (for two isolates because of those isolates give variable biochemical test results which confused their diagnosis that lead to using of vitek system technique to diagnosis them, these isolates were rare bacteria that infect tonsil and adenoid). The most common types of bacterial isolates were Staphylococcus aureus which accounted for 75 isolates (23.6%), followed by Streptococcus pyogenes 61isolates (19%), Escherichia coli 57 isolates (18%), Klebsiellae pneumoniae 55 isolates (17.3%), Hemophilus influenza 37 isolates (11.6%), Sphingomonas paucimobilis 14 isolates (4.4%), Staphylococcus epidermides 7 isolates (2.2%), Pseudomonas aeruginosae 6 isolates (2%), Pseudomonas stutzeri 5 isolates (1.6%), and Staphylococcus saprophyticus only one isolate (0.3%).Regarding the bacterial population, there is a difference between tonsils / adenoid surface and tonsil/ adenoid core culture were the most predominant isolate from tonsil surface was Staphylococcus aureus and K. pneumoniae from tonsillar core, while from adenoid surface was Streptococcus pyogenes whereas E. coli from adenoid core.The ASO titer in patients with or without group A streptococcal infections were determined by using latex agglutination test. The results revealed that 8 samples (14%) exhibited positive results, while 49 samples (86%) exhibited negative results out of 57 samples. The results showed statistically no significant differences between patient age groups but showed highly significant differences between males and females.Eight specimens were taking for histopathological examination randomly, four samples were adenoids and four samples were tonsils. The histopathology examination of tonsil and adenoid showed the presence of lymphoid hyperplasia,multiple lymphoid follicles, vascular congestion, fibrosis, germinal centers, infiltration of inflammatory cells, necrosis and apoptosis of tissues

In this study, (85) blood specimens were collected from (85) patients with suspected septicemia, age ranged between 1to 28 days from both sexes (53 males and 32 females) during the period from November 2014 to March 2015.The results of this study revealed that (52.9%) are presented with late onset sepsis (infected during 7 - 28 days of their life), while the rest (47.1%) of the neonates are presented with early onset sepsis (infected during the first seven days of their life). The collected samples were investigated for bacterial isolation. Bacterial culture was positive in (7.06%) patients versus (92.9%) patients revealed a negative bacterial culture. The most common types of bacteria isolated were three isolates of Klebsiella spp. (50.0%), followed by one isolate Staphylococcus aureus (16.67%), one isolate E. coli (16.67%), and one isolate Enterobacter spp. (16.67%).The virulence factors of some bacterial isolates in this study were studied. The capsule was present in all bacteria isolated in this study (100%) except for Enterobacter spp. which did not possess the capsule.Colonization factor antigens were detected in all isolates. It was found that only Klebsiella spp. and E. coli (100%) have the ability to produce CFAI and CFAIII. Whereas Enterobacter spp. and Staphylococcus aureus (100%) have the ability to produce colonization factor antigen I only. The results also showed that all isolates of Klebsiella spp. and Enterobacter spp. did not produce hemolysin, while all isolates of Staphylococcus aureus and E. coli were able to produce hemolysin.Extracellular protease was also investigated. It was found that (100%) of all bacteria isolated in this study were able to produce extracellular protease.Biofilm formation was investigated in all bacterial species, and the results showed that all isolates of Gram negative bacteria and Gram positive bacteria form a biofilm.The ability of some bacteria to produce bacteriocin was tested and the results showed that E. coli and Klebsiella spp. were able to produce bacteriocin.In - vitro, the susceptibility of bacteria towards some antibiotics included in this study revealed that the amikacin and kanamycin are the most effective antibiotics to different types of pathogenic bacteria. Finally, molecular detection for bacterial sepsis was done by using specific primers (16 sRNA, rpoB and its). It was found that 16 sRNA genes were present in (20%) of samples and rpoB gene present in (18.8%). While its gene used for detection of fungi revealed negative results in all samples.

Abstract: كائن Bacillus cereus موجود في كل مكان وهوممرض منقول بالاغذية والذي يمكن ان يسبب نوعين من امراض الجهاز الهضمي : القيء والاسهال. في هذه الدراسه, تم جمع 140 عينه غذائية شملت (الرز, اغذية الاطفال، الدقيق، منتجات الالبان، اللحوم، الحليب , التوابل) جمعت عشوائيا | Bacillus cereus is a ubiquitous organism and a potential foodborne pathogen that can cause two types of gastrointestinal diseases : emesis and diarrhea. In this study, a total of 140 food samples included (rice, infant food, flour, dairy products, meat, milk powder and spices) were collected randomly from restaurants, food stores and various sale points in the local markets of the Hilla province during the period of November 2014 to April 2015 in attempt to isolate of Bacillus cereus from these samples and detection the prevalence of diarrheal (hbl and nhe) and emetic (ces) enterotoxins genes by using Polymerase Chain Reaction (PCR). All bacterial isolates were identified by cultural, microscopic and biochemical examinations. The results showed that 56 (40%) of samples showed positive growth for Bacillus cereus. The antibiotic sensitivity test of some isolates to 10 antibiotics was studied. It has been found that all B. cereus isolates were resistant to Ampicillin, Ampiclox, Cefotaxime, and Cephalexin, while all isolates were sensitive to Gentamycin, Ciprofloxacine and Chloramphenicol, but most of them showed different rate of sensitivity to one or more of antibiotics such as Neomycin 90% and 80% for both Tetracycline and Erythromycin. Polymerase Chain Reaction technique (PCR) was used to detect the ability of bacterial isolates to encode two types of enterotoxin genes, diarrheal and emetic genes. The results showed that 4(7.14 %) of isolates harboured hblA gene, 16 (28.57%) hblC, 5(8.92 %) hblD, 46(82.14%) nheA, 24(42.85%) nhe B, 26 (46.42%) nheC and 3(5.35%) of the isolates harboured Ces gene. On the other hand, through using PCR it was found that nhe gene was present in most isolates, while hbl gene was variable among the studied isolates. Moreover, the Ces gene was found only in isolates being isolated from rice samples, while it was not found in other types of samples.

The rate of toxoplasmosis and of subclinical infected infants at birth with the risk of late manifestation is still unclear, whereas such data are fairly well - known for Rubella , Cytomegalovirus and Herpes virus. The respective major diagnostic issues in pregnancy, the laboratory diagnosis, and its rational use in combination with clinical information are presented , also the value of passive prophylaxis, therapy, and prenatal diagnosis as well as the possible management for diminishing the infection problems in pregnancy.Aims of study : The study was aimed to evaluate the ELISA result for Toxoplasma, rubella, cytomegalovirus (CMV) and Herpes virus (TORCH) IgM and IgG and compare the results of the ELISA with RT - PCR to arbitrate discordant results.Methodology : The present study was carried out on 57 pregnant women, all of them had with bad obstetric history (BOH) of abortion twice or more. Patients were between 15 - 40 years of age, and they were attending Al - Zahraa Maternity and pediatric Teaching Hospital, Al - Hakeem Hospital and some private clinics, in AL - Najaf province during the period from May 2012 till May 2013. Serological evaluation for TORCH infections was carried out by using IgM and IgG Enzyme Linked Immunosorbent Assay (ELISA ) method and molecular technique ( DNA; RNA - RT - PCR). Each blood sample was divided into two part , one part plane tube for separation of serum that were screened for the presence IgM and IgG antibodies against Toxoplasma gondii ,Cytomegalovirus Rubella virus and Herpes simplex virus by using (ELISA test ).The tests were performed according to manufactures instruction.The other part (blood )EDTA tube was used for DNA 0f detection Toxoplasma , CMV and Herpes simplex virus , while RNA extraction of Rubella virus.The blood and serum sample were stored in refrigerator (2 - 8C?) before the analysis.The extracted DNA and RNA were stored at - 20C? till used within 24 hours. All ELISA Results samples were compared with Real - Time PCR result. Statistical analysis : Statistical program SPSS version (20.0) was used to study the significant difference between tests in each type of antibody (IgM and IgG). (X2 - test) was used after detection of normal distribution to the data and appropriate P<0.001 consider significant. Results : Both IgM / IgG was Seropositive to T. Gondii , Rubella , CMV and HSV - 2 which were 49.12/80.70%, 21.05/49.12% , 45.61/70.18% and 1.21/36.20% respectively. Samples were seropositive to IgM and results were retested by RT - PCR method. Maximum number of IgM /IgG seropositive cases of aborted women was 19(32.75%)/57 that associated with Toxoplasma ,Rubella and CMV infection by RT - PCR ( 10(17.54%), 6( 10.53%) and 3(5.26%) respectively ). The ELISA TORCH IgM and IgG assays provided results comparable to RT - PCR indicated significant differences among Toxoplasma and viral infection. The ELISA TORCH infection IgM and IgG assays showed a lower specificity with for Toxoplasma IgM (p=0.001), poor for CMV IgM and moderate for Rubella virus IgM.Conclusion : The accurate diagnosis of TORCH infection should be done by molecular method.

Abstract: جمعت 100 مسحة فموية من مرضى تسوس الاسنان وامراض ما حول الاسنان الذين تراوحت اعمارهم ما بين 15 - 65 سنة ومن كلا الجنسين والذين راجعوا المركز التخصصي لطب الاسنان في الديوانية للمدة من كانون الاول 2012 الى اذار 2013 لغرض قياس التعبير الجيني لمورثة البروتين ا | A total of 100 oral swabs were collected from patients suffering from dental caries and priodontal infections, ranging from 15 - 65 years old of both genders whom admitted to the Al - Diwaniyah Teaching Special Center of Dentistry within the period from December 2012 to March 2013, in order to quantify the gene expression of biofim regulatory protein (Brp A) in Streptococcus mutans isolates by using the Real Time polymerase chain reaction. According to morphological, cultural characteristics and biochemical tests by using VITEK - 2 system, 34/84(40.47%) isolates of S.mutans were isolated and identified among streptococcus species and the isolation percentages were 26/50(52%) in males and in females were 24/50(48%), while the age group (15 - 25 years old) was the most affected than the other groups. The statistical analysis showed no significant differences among the interaction between gender and age groups. Molecular detection of 16s rRNA gene was amplified to confirm the diagnosis of S.mutans isolates, where all isolates gave an amplicon size (151) bp, in addition to, the DNA sequencing was done in order to identify the nitrogen bases sequences and phylogeny of local isolates in comparison with the global isolates (Spain, Japan, Korea, USA, Canada, India), results revealed that the local isolates of S.mutans had a similarity percent (90%) with Spain isolates.Furthermore, the susceptibility of isolates to a variety of antibiotics have been investigated. It has been found that isolates had multiresistance to erythromycin(88.2%),ampicillin(76.4%),amoxiclave(70.5%),tetracycline(61.7%), nalidixic acid and amoxicillin (58.8%), chloramphenicol (55.8%). The statistical analysis showed a significant differences among tested antibiotics. Biofilm formation was investigated phenotypically by using tissue culture plate with crystal violet staining for resistant S.mutans isolates, the results revealed that all isolates were high biofilm former, furthermore, the effect of ethanolic extraction (50%) of curcumine in growth inhibition and biofilm reduction of S. mutans was assayed. The results showed an effect of curcumine in comparison with chlorhexidine(2%) as a control.The gene expression of biofilm regulatory protein A(Brp A) was quantified in comparison with housekeeping gene 16s rRNA as a reference gene of biofilm S.mutans by using reverse transcriptase polymerase chain reaction (RT - PCR). The results revealed that the expression (relative&absolute) of Brp A gene is decreased in the test treatment (S.mutans with 1% glucose+ 50% curcumine) in comparison with control (S.mutans grown in 1% glucose only).In conclusion, the present study established the role of Brp A gene in biofilm formation

Abstract: The present study was performed to identify the species and strain of Leishmania parasite isolated from different endemic areas. It was carried out on cutaneous leishmaniasis (CL) in five Iraqi provinces as following : Al - Najaf province ( Al - Hakeem and Al - Sadder teaching hospitals), Babylon province ( Marjan hospital ), Al - Qadisya province (AL - Sadder Teaching hospital ), Karbala province (Al - Hussain General Hospital) and Kut province (Al - Zehraa Teaching and Al - Kerama Hospitals). It covered seven hospitals as a field of investigations from October 2010 to December 2012.Cellulose acetate electrophoresis has been performed in Walter Reed Institute of researches in USA. A total of 126 cases comprising 48(38%) females and 78(62%) males were studied. The highest infected age group was 21 - 30 years with a rate of 27.8% and the lowest rate was 11.9% at the age group of 10 and less years.Geographical distribution of CL among hospital patients indicated that rural areas were with highest rate (54%) while in urban areas were with(46%).The number of ulcers per one patient differs for each patient. The highest rate of multiple lesions was 73% in comparison with single lesion (27%).The type of infection showed that disease was in wet type (82.5%) more than in dry type (17.5%). Direct smears were made by lesion aspiration,skin scraping and discharged blood methods , by which 90 (71%) patients gave positive result under light microscope.Modified NNN medium and RPMI - 1640 with fetal bovine serum followed by sub - culture in drosophila Schniders media were performed for each case. Out of 126 cases,83(65%) gave positive growth. Further characterization of the causative parasite species and strain made by molecular and biochemical techniques.Out of 83 postive growth culture,only 52 specimens were studied by nested - PCR, using kinetoplast minicircle fraction amplification to detecte the species of parasite.It was found that 45(86.5%) cases in the generation of a 560 bp DNA and 7(13.4%)patients displayed a fragment of 750 bp, corresponding to L. major and L. tropica, respectively.This test revealed that L. tropica and L. major are the causative agents of infection with dominant shifting to the L. major.Cellulose acetate electrophoresis (CAE) was performed for 20 mass cultivated cultures. Isoenzyme profiles of these isolates were compared with reference strains of Leishmania spp. using cellulose acetate electrophoresis and 4 enzyme systems (glucose phosphateisomerase,leucil phosphate,manose phosphate isomerase and 6phosphogluconate dehydrogenase). The results showed that L.major(LV39) isolate were in 20 mass cultivated culture.Most of the CL patients in Najaf province(2011,2012) were from Haidariya in north district. High prevalence of disease was observed in Autumn and Winter.The highest number of cases was recorded during February and December.

Abstract: This study was done to investigate whether Type 2 diabetes and Latent autoimmune diabetes of adult (LADA) patients have similar or different immunological profile.Therefore, measurement of serum levels of adhesion molecules (Serum intracellular cell adhesion molecule(sICAM - 1), Serum vascular cell adhesion molecule (sVCAM - 1) and Serum endothelial Selectin (sESelectin)), chemokines (CCL2, CCL3 and CCL4) and cytokines (IL - 6, IL - 1receptor antagonist and IFN - ?) in these patients was done. In addition to the influence of BMI, gender, age and diabetes duration on these systemic immune mediators were analyzed. Also, the relationships of the in vivo levelsof these mediators with micro - & macro - vascular complications in type 2 diabetes & LADA were studied.Three hundred individual were enrolled in this study and were divided into two subgroups : patients and control groups (280 patients& 20 control). From the 280 patients group who were clinically diagnosed as type 2 D.M., 34 patients were GADA positive and considered as LADA cases. Serum samples were taken from The 34 LADA cases, 36 cases of D.M.2 (selected randomly from the remaining 246 diabetic type 2 patients) & 20 healthy control subjects.The prevalence of LADA among D.M.2 patients was 12.1%. A significant difference in family history, BMI, FBS, HA1C & duration of D.M. was found in D.M.2 cases compared to LADA cases. The mean sVCAM - 1level of control group was significantly lower than D.M.2 and LADA group, P<0.05. The sE - Selectin level was higher in LADA group than control and D.M. type 2 group & significantly different when compared to control group (P<0.05). The sVCAM - 1 level had a significant positive correlation (R=0.25, P=0.017) with BMI in all groups. LADA group had significantly higher values of CCL2 while D.M. type 2 had the least values (P=0.002). The mean IL - 6 of D.M. type 2 group was (11.6±3.1), for LADA group it was (12.4±1.7) and for the controls it was 0.95 ± 0.14. There was a statically significant difference between D.M.2 vs. controls, and LADA vs. controls (P<0.05), regarding the mean IFN - ?, it was significantly higher in LADA group than D.M.2 group (87.5 ± 20.3) vs. (40.3 ± 4.5) respectively, (P=0.032).The mean IL - 1receptor antagonist was significantly higher in D.M. type 2 and LADA cases than controls (P<0.05). A significant positivecorrelation between IL - 6 and sICAM - 1, (R= 0.27, P= 0.013) & a highly significant positive correlation between IL - 6 and IL - 1RA, (R= 0.35, P=0.001) were found. IL - 6 & IL - 1RA serum levels in D.M. type 2 patientswere significantly associated with the complications where p - value?0.05. For conclusions, LADA is clinically underestimated among D.M. type 2 patients and increases with increasing age. Also, Levels of CCL2 and IFN - ? are associated with autoimmunity, Levels of adhesion molecules & chemokines are associated with complications of diabetes.
