المستخلص: This study was conducted in order to investigate the role of magnetically water in the rooting of fresh and aged (phaseolus aureus roxb.) cuttings, and the impact of treated water in some morphological criteria and biochemical that interfere in the induction of rooting in cuttings and fall clearly when delayed induced auxin treatment in aged cuttings. Study was conducted in the laboratories of the Department of biology at the University of Babylon, for the period 2012 - 2014 was the use of magnetic therapy devices (Magnitron) of water with three gauss 1000, 2000.3000 so as to provide a magnetic flow to distilled water and river water and used as well as the complete randomized design and analyzed the results statistically significant and valuable knowledge LSD to extract the significantly differences between the treatments and the results were as follows : Physiological parts1. Increase the number of roots significantly in cuttings when treat for 24 h.with auxin dissolved with distilled water processor in 1000 gauss amounted to 77.75 root / cutting.2. The results showed that the roots rate increased significantly in the treatment of fresh cuttings treated in distilled water processor 1000 gauss gave 64 root / cutting. As well as the rest treatments affect in rooting increase as given (58, 52.25) root / cutting for each of the treatment 2000.3000 gauss, respectively.3. The treatment of river water as well as magnetically influenced in increasing the number of roots significantly in three processes and the highest being in the 1000 gauss(84) root / cutting.4. The results showed that distilled water processor magnetic effect is significant in the processes that occur during ageing of the cuttings, which led to a reduction in rooting rate in aged cuttings, as it was observed that the treatment of the cuttings for 72 - hour in 1000 gauss is the best of the rest of the treatments amounted to 48 root / cutting. As the impact of river water processor magnetically significantly increase the number of roots in the aged cuttings as treatment given to 1000 gauss higher values 70 root / cuting.Biochemical parts.1. The results showed that chlorophyll content increased significantly when using the river water wizard three intensities (18.09, 17.43, 16.99) (spad) intensities of 1000, 2000.3000 gauss respectively.other each of distilled water and river water processor magnetically in 1000 gauss increase in chlorophyll content to 16.07, 18.57 (spad) respectively in aged cuttings.2. It was observed that the treatment of auxin dissolved in three intensities impacted significantly on the effectiveness of antioxidants defense system and the highest being at the treatment of the cuttings in auxin dissolved water magnetically processor in 1000 gauss, as was the effectiveness of the enzyme SOD 1.85 unit in the effectiveness of the enzyme CAT reached 15.30 unit and increased GSH content to 0.914 mg / g when compared with the control treatment.3. influenced the treatment of fresh cuttings in distilled water magnetically processor with three intensities are equally matched in the effectiveness of SOD and CAT, and the highest being at 1000 gauss magnetic intensity as it affected the effectiveness of the CAT to 31.62 units. Magnetic intensity also affected the same increase in GSH content reached significantly to 0.710 mg / g.4.

Therefore this study was aimed to detection and isolation of Coxiella burnetii as a causative agent of abortion in woman and female of small ruminants.352 samples were collected includes human samples and animals samples. A total of 120 blood aborted women, 7 breast milk samples, 20 placental samples and 50 blood samples from normal women as control groups, these samples collected from Bent Al - Huda hospital in Thi - Qar province. Animals samples, a total of 80 aborted animal blood samples, 15 milk samples, 10 placental samples and 50 blood samples, these samples from normal animals as controls group, these samples collected from veterinary hospital in Thi - Qar province. The results of this study showed a high incidence of abortion occurs in first trimester of gestation (41.666%) and high incidence in rural regions (64.16%) and also age group from 21 to 30 years old (50%).The methods used for detection of Coxiella burnetii includes serology tests, polymerase chain reaction (PCR) technique for confirmation serological test and isolation on embryonated chicken eggs and detection by PCR technique. Out of the 120 women serum samples analyzed by enzyme ELISA, the results of percentage of anti - Coxiella burnetii IgM and IgG in human samples were 36 (30 %). The percentage of anti - C. coxiella IgM in human samples were 10 (8.333%), while the percentage of anti - C. Coxiella burnetii IgG in human 26(%21.667%).. In animals total of (80) serum samples, the percentage of anti - C. coxiella IgM and IgG in animals' serum samples were 31(38.75%) The percentage of anti - Coxiella burnetii IgM in animals 10 (12.5%), while, the percentage of anti - C. coxiella IgG in animals are 21(26.25 %). PCR technique used for identification of Coxiella burnetii in human and animals samples by targeting three genes including outer membrane protein (com1 and com2), 16S rRNA and transposase insertion element (IS1111) genes. In human blood samples the com1 and com2 genes detected in 23of 120 (19.166%) samples and in breast milk samples 1 of 7 (14.28%). and not detected in placental samples. The 16S rRNA gene was detected in 16 of 120 blood samples (13.33%) and in breast milk samples and placental samples were not detected. The IS1111 gene was detected in 9 of 120 blood samples (7.5%) in human blood samples, also were not detected in milk and placental samples.. In animals blood samples the com1 and com2 genes were detected in 19 of 80 blood samples (23.75%) and were not detected in milk and placental samples. The 16S rRNA gene detected in the same percentage of com1 and com2 genes 19 of 80(23.75%) and in the milk samples and placental samples not detected. The IS1111 gene detected in 10 of 80 (12.5%) in animal blood samples, also were not detected in placental samples.

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

المستخلص: من خلال البحوث والدراسات التي اجريت على اسباب وهن حركة النطف لدى الرجال الا انه هناك عدد من المسببات لم تحدد والى الوقت الحاضر. الا انه بالرغم من ذلك بعض الدراسات تشيربان العامل الوراثي يلعب دور في ذلك والمتمثل بعضيات المايتوكوندريا والحاوية على الدنا الم | Through researches and studies done on the causes of the asthenozoospermia in men, although there was no specific reason so far responsible for the infertility in people, but some of the studies were indicated that the genetic factors plays a role in the sperm dysmotility through the mitochondria that contained mitochondrial DNA responsible for providing the energy required for the sperm motility by production of ATP, which serve as the fuel that is consumed by sperm during motility. This study is conducted to determine the changes that could occur in the sperm mtDNA which included (common deletion, mtDNA copy number per cell and mutations in the ATPase8 and ATPase6 genes).This study was consisted of two parts as follow : The first part was consisted of two steps : The first step conducted on 71 samples from subjects suffering from the weakness of the movement of sperm and 12 samples from subjects who have a normal movement of sperm, total samples were 83 samples were divided patient samples into 5 groups depending on the percentage of the sperm motility under the classification adopted by the World Health Organization as well as a control group, that it has become 6 groups, these samples were subjected for investigation about the mitochondrial DNA deletions and mitochondrial DNA copy number by using real time PCR.On the other hand was taking 66 sample dispersed sample 56 patients and 10 healthy samples were subjected to the tests of ATPase6 and ATPase8 genes sequences for detection about mtDNA mutation.The second step was included the use of discontinuous gradient centrifugation (percoll) , which are 40 % and 80 % which represent both progressive and non progressive motile sperms, bringing the total samples 166 samples that collected and fractionated in a hospital, Kamal Al - Samarrai to treat infertility and IVF in Baghdad and examined for further molecular investigations for the period from February 2012 to October 2013.The second part was included the molecular tests that carried out after DNA extraction from the cells and this part include three steps : The first step was to investigate the common deletion in mtDNA where the results showed that the total number of deleted samples in the group (0 - 5) in the nonprogressive sperm was 81.25 %, which ranged between 6.8 - 74.7% while the ratio between the other groups 6 - 10, 11 - 15 , 16 - 20, 21 - 25 where were 75, 35.72, 28.5 , 36.3, and 12% for control group respectively. The second step was to investigate the sperm mtDNA copy number. The same groups where the results showed that the content of DNA in subjects with impaired movement of sperm was high compared with the control group where scored in some samples the highest level of gene expression 246.9 copies per cell in the group (0 - 5%) either other groups have shown lower levels were observed in groups (6 - 10) , (11 - 15) , (16 - 20) and (21 - 25) were 203.1, 180.7, 133.5 and 128.3 copies per cell, either the highest level of DNA content of the control group was 94.7 copies per cell, there was also a significant difference (P>0.05) between the normospermic motile isolated from 80% class and poor sperm movement isolated from 40 % class. The third step was included the detection of mutations by analyzing the sequences of the MT - ATAase8 and MT - ATPase6 genes which documented 59 mutations that were 23 missense and 36 silent mutations where all of them were heteroplasmic mutation except for a single mutation of the type missense (A8860G) which was homoplasmic mutation was noticed in all mtDNA copies of patients and control subjects also in progressive and non progressive sperm cells. Thought this current study novel nucleotides changes in MT - ATAase8 and MT - ATPase6 genes among groups where 3 novel missense mutations in MT - ATAase8 gene at positions (8378, 8483 and 8558), the changes of nucleotides bases were A>G, A>C, A>C and A>C respectively, replacing Asparagine to Aspartic acid, Leucine to Proline and Proline to Alanine respectively. Also two novel missense mutations were observed in MT - ATPase6 gene at positions nt (8822 and 9055) where the changes nucleotides were (C >T and G>A) that replaced amino acids (Serine to Phenylalanine and Alanine to Threonine) respectively. Silent novel heteroplasmic change as a transition substitutions in ATPase8 gene at position nt (8371) by replacing C>T without any changing in amino acid of protein. Results of this present study showed novel heteroplasmic silent mutations in ATPase6 gene at positions nt (8899, 9048 and 9060) nucleotides changes (C>T, T>C and C>A) respectively, without changing in amino acid of protein which were observed in infertile group

المستخلص: شملت الدراسة جمع 60 عينة من مصادر بيئية مختلفة ضمت ترب ملوثة وغير ملوثة بالمركبات الهايدروكاربونية ومياه بزل في محافظة الديوانية ومن مصادر سريرية لمرضى اخماج المسالك البولية في مستشفى الديوانية التعليمي, للمدة من 28 كانون الثاني2013 حتى 1 شباط 2014. هدفت | This study included collection of 60 samples from different environmental sources involved contaminated and non contaminated soils by hydrocarbon compounds and from drainage waters in Diwaniyah province and clinical sources in Diwaniyah teaching hospital, for the period from 28 January 2013 to 1 February 2014. This study aimed to isolation and identification the species of Pseudomonas and metabolic efficiency test in the analysis of petroleum hydrocarbon compounds and measure the effectiveness of antagonism in resistant pathogenic fungi to tomato plant. Thirty four isolates were identified, the Pseudomonas spp. was the highest frequency with 22 isolates. These isolates distributed to 16 isolates of pseudomonas aeruginosa and 6 isolates of pseudomonas fluorescens. Also this study included isolation of two pathogenic fungi which were Alternaria alternate and Fusarium solani in tomato plant. Statistical analysis revealed significant differences at (p<0.05) between the bacterial isolates in their analysis of hydrocarbon compounds, when the optical density measurement as an indicator of the effectiveness of growth on hydrocarbon sources. All isolates showed different optical densities were highest isolation of pseudomonas aeruginosa isolated from urinary tract infections as optical density amounting to 0.23nm. Also showed an increase in electrical conductivity values for all isolates within the incubation period, the highest value to the hospital (1) isolate with 12.8 mc/cm in the third week of the incubation, But decreased in the sixth week to 8.7 mc/cm and all isolates showed a good effectiveness of electrical conductivity in the third week and noted significant differences (p<0.05) in electrical conductivity values for isolates compared with control of 7.2 mc/cm. The results of the DNA electrophoresis of the all isolates contain the two genes (C23O and rhIB) which they code for the production of hydrocarbon - degrading enzymes. In Bio - antagonism experiments noted that all isolates were inhibitory to the growth of two pathogenic fungi and stimulating the growth of tomato plants in glass and field experiments through increase germination, vegetative ratio and root length and increased weights with significant difference at (p<0.05)with seed treatment with fungus only. The best isolates increased in germination were pseudomonas aeruginosa hospital isolate and pseudomonas fluorescens generating isolate which had stimulated germination rate to 76% with significant difference when compared with the control of Alternaria alternata and Fusarium solani which germination rate was 36 and 40 respectively. Pseudomonas aeruginosa which isolated from soil was more efficient in increasing the length of the stem, the stem height was 7.53 cm compared with the control treatment with F. solani, the stem height was 5.7 cm. Pseudomonas aeruginosa hospital which led to an increase in the length of the total root to 3.66 cm compared with the control treatment with F.solani at 1.53 cm. The increase in fresh and dry weights of Total vegetative reached 0.64 gm and 0.065 gm respectively when the treatment of seed contaminated with F.solani fungus and pseudomonas aeruginosa hospital isolate compared to the control which the weights were 0.11 g and 0.011 gm respectively. The highest increase in fresh and dry weights of total root of 0.057 gm and 0.0072 gm respectively when treated seeds contaminated with the F. solani with P. fluorescens hydrocarbon contaminated soil isolate compared with control that the fresh and dry weights was 0.032 g and 0.0017 g respectively. The highest value of stem length registered when treating seed with A. alternata which was 7.5 cm when treating seed contaminated with A. alternata by P. fluorescens isolated from soil contaminated with hydrocarbon compounds. The lowest value of stem length was 7.3 cm for the treatment of seeds contaminated with the A. alternata by P. aerugionsa isolated from the drainage water compared with control treatment (seeds contaminated with A. alternata) which stem length was 6.33cm. As for the fresh and dry weight for total vegetation was the highest value of 0.8 gm and 0.793 gm respectively when the treatment of seeds contaminated with the A. alternata P. aerugionsa isolated from urinary tract infections and the lowest value of fresh weight was 0.61gm for total vegetation when treated seeds contaminated with the A. alternata by P. aerugionsa isolated from soil non contaminated with hydrocarbon compounds and 0.069 gm when treated seeds contaminated with the A. alternata by P. aerugionsa which Isolated from drainage water compared with control treatment which were 0.15 gm and 0.0014 gm of fresh and dry weight for total vegetation, respectively. As for fresh and dry weight of total root were the highest value 0.071 gm and 0.008 gm respectively, when the treatment of seeds contaminated with the A. alternata by P. fluorescens isolated from soil contaminated with hydrocarbon compounds. while the lowest value were 0.058 gm and 0.0065 gm when treated seeds contaminated with the A. alternata by P. aerugionsa isolated from soil non contaminated with hydrocarbon compounds compared to control treatment (seeds contaminated with the A. alternata only)which the fresh and dry weight values for total root were 0.046 gm and 0.0018 gm respectively. When antagonism study in the glass field, the highest percentage of inhibition of the growth of the F. solani on PDA and cetramide agar were 42% and 61% respectively, when treated with P. fluorescens generator isolate. While the bacterial antagonism with A. alternata on PDA media, the highest percentage of inhibition 51% when treated with the transaction P. fluorescens generator isolate on PDA media. Generally, the treatment of pathogenic fungi with biological control bacteria had reduced the percentage of infection and increase the percentage of germination.

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

المستخلص: This study includes 82 clinical samples from male patients suspected to have gonorrhea (urethral discharge with dysuria). Two types of samples were collected from each patient, urethra swab and blood samples from patients who attended Al - Yarmouk teaching hospital in Baghdad city, Clinics and private laboratories during a period from December 2012 to April 2013. All of them were married and have children's, and 20 samples were taken from apparently healthy subjects.Cases caused by gonococci were diagnosed by finding the Neisseria gonorrhoeae bacteria in the samples using microscopic examination and culturing on rich media chocolate agare for growth bacteria and selective media modified Thayer martin agar (MTM) contact antibiotic to prevent growth of all the types of bacteria except N. gonorrhoeae.Microscopic examination using specific kit for gram stain, showed gram negative diplococcus, like bean shape. Culturing on rich media revealed that 82 (100%) samples positive but re culturing on Modified Thayer martin media revealed that 76 (92.68%) out of 82 positive. Then biochemical test had the same results.Results of the molecular diagnosis of the bacteria causing gonorrhea using specific primers that were specific for the Orf1 gene, revealed that 80.26% of samples (61 out of 76) were positive. Results of the microdeletion in Y chromosome AZFc region revealed that no microdeletion were occurred in SY - 254 STS and BPY - 2 gene.This study, provided high specificity and sensitivity for the diagnosis of gonorrhea using PCR technique which is cheaper and faster than traditional methods. Also, PCR - based method for detection of N.gonorrhoeae can be readily used in hospitals and laboratories.

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

المستخلص: This study has been conducted for the first time in Najaf / Iraq, and the study included the preparation of a local inactivated vaccine (whole and subunit).The number of cases infected with seasonal influenza virus were 647 cases out of one thousand suspected case. They were distributed into eleven groups. Seasonal influenza virus was detected by two diagnostic methods (rapid test device and real time PCR).The present study has reflected that the most diagnosed cases infected with seasonal influenza virus during the period extended from March 26, 2012 up to April 30, 2013 represented by were type A (H3N2) (283) cases. Whereas H1N1 (148) cases, H3N2+H1N1, (56) cases, H1N1 + H3N2 + B were (30) cases and 130 cases were infected with type B.Current study also revealed that age group of 46 - 60 years old infected with seasonal influenza virus were (159) case including (368) male and females were (279) of different infected group..The spread of seasonal influenza virus in Najaf varies from one region to another depending on the population density. Clinical cases were collected randomly during the months of the year. It has been found that the spread of disease has something to do with temperature and humidity as high humidity and low temperature lead to increased spread of the disease because of their relationship at the stage of the spread of epidemic influenza that spread from Dec 26, 2012 and up to April 1, 2013 in addition to expatriates infected..Two techniques were used for isolation of seasonal influenza virus first inoculation of embryonated chicken egg and secondly chicken fibroblast cell culture.It was found that at the embryonated egg lethal dosage (ELD 50 / 0.5 ml) (109.6) whereas tissue culture infective dosage (TCID50 / 0.1 ml) was (109.3) of (H1N1+ H3N2) and type (B) virus..Virus was purified by two ways that are depending on the vaccine type. The gamma irradiation that dosage used for inactivating vaccine of the purified virus which was extracted from allantoic fluid and tissue culture was (5.702) mSv/h for subunit virus vaccine type whereas gamma irradiation dosage for complete (whole) virus vaccine was (8.816) mSv/h. The results proved that immunoglobulins (IgM, IgA and IgG) levels as well as (IL - 17, IL - 10 and INF - 1?) indicated significant differences among vaccinated, infected and control groups.Subunit and whole virus vaccine extracted from chicken fibroblast cell culture are considered the best of derived from virus propagated in embryonated chicken eggs.Subunit virus vaccine is better than the whole virus vaccine derived from virus propagated in embryonated chicken eggs and extracted from chicken fibroblast cell culture.The current study also reflected that locally prepared virus subunit vaccine and purified whole virus killed vaccine capable of inducing humoral and cellular immune response in experimentally vaccinated rats..Histopathological changes appeared clearly on tissue sections (lung, trachea, heart, liver, spleen, kidney) of the infected group as compared with control and the vaccinated groups.

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

Toxoplasmosis was diagnosed in 28(56%) out of 50 abortive placenta and in 57(57%) out of 100 non abortive placenta (normally delivered women), these samples of placenta were microscopically examined after homogenizing and staining by Gimsa and Leishman's stain The parasite development stages were also noticed including developing from the tachyzoites into the oocysts stage and the histopathological effects resulting from infection in the placenta in both aborted and normally delivered women which were represented by necrosis, vaculation and cells degeneration , inflammatory cells infiltration and the focal inflammatory reaction in the villi in addition to hemorrhage and accumulation of eosinophilic substances, the results also showed that 41 (82%) of aborted placenta and 18 (18%) of non abortive placenta (normal delivered women) were infected with Toxoplasmosis by using the laboratory Balb/c mice inoculation method while, some cases of inflammation were diagnosed in the brain, of the experimental infected mice, which were represented by the inflammatory cells infiltration and the prevailing of gliosis, tissue necrosis vaculation and cells degeneration.This study revealed that laboratory mice inoculation in the peritoneal cavity is a useful and efficient method in the detection of the parasite in infected placenta as compared with the microscopic examination of direct smears and examination of tissue sections from placenta.The present study showed an overall percentage of infection among aborted women was (92%) while (58%) showed an acute infection and (34%) chronic infection, in another hand the infection rate among normally delivered women was (70%), and it has been found the infection rate among acute and chronic cases were (41%), (20%) respectively, Its to be noted this is the first time in Mosul City for such a study conducted in this area concerning the congenital Toxoplasmosis in newborns with an infection rate (9%).In this study, sera were tested by Latex (LAT), and Enzyme Linked Immunosorbent Assay (ELISA). It was shown that IgG - ELISA is the most sensitive to diagnose the infection as compared to other tests.These study also concerned with the isolation and diagnosis of Toxoplasma gondii parasite from blood by inoculating the blood samples in laboratory Balb/C mice the rate of infection was (16%) in laboratory mice inoculated with blood collected from aborted women while the infection rate in laboratory mice inoculated by blood samples (mother and her neonatal cord blood) collected from normally delivered women appear in (12%) & (16%) respectively. The rate of occurrence of the specific antibodies against Toxoplasma gondii was identified, The highest rate was found for the type (IgG+ - IgM+), in both aborted and normally delivered women with percentage reach (40%) & (26%). The titer (100 IU/ml) of the specific IgM & IgG antibodies was found in high rate reached (75%), (43.5%) in mother blood, also found in a high percentage in the neonatal cord blood estimated as (50%), (64.4%) for the specific IgM & IgG antibodies respectively, in another hand the titer (100 IU/ml) was also found to be the more predominate titer in blood samples of aborted women with percentage reached to (50%) & (60.5%) for the specific IgM & IgG antibodies respectively.

المستخلص: ا جريت هذه التجربة في قسم علوم الحياة / كلية العلوم / جامعة الكوفة في محافظة النجف الاشرف وتضمنت مرحلتين : الاولى زراعة البذور لغرض قياس نسبة الانبات للمدة من 1 / 8 لغاية 8 / 8 / 2011 وانتاج الشتلات للمدة من 15/8/2011 ولغاية 14 / 9 /2011 في حقل خاص لانتا | This experiment was conducted in the Department of Biology, College of Sciences, University of Kufa in Al - Najaf Al - Ashraf province. It included two periods : the first was seed sowing to measure germination percentage from 1 - 8 till 8 - 8 - 2011, and transplants production from 15 - 8 - 2011 till 14 - 9 - 2011 in a private farm for vegetable transplants production. The second was transplanting in an open field belongs to Plant Production Department/Kufa Technical Institute from 15 - 9 - 2011 till 17 - 1 - 2012 to measure plant growth parameters and curd cauliflower production cv.solid snow in harmless environment techniques. The experiment was adopted as factional experiment. The treatments were distributed according to Randomized Complete Block Design (RCBD) with four replicates. The experiment included the study of two factors : the first, was five magnetic intensities for treating waters magnetically (0; 500; 750; 1500 and 2500 Gauss) by means of dipolar magnetrons. The second was three quantities of plant organic manure(rice residues).i.e.(0, 2.5 and 5.0 kg/furrow) with a length of 6.5 m. and their interactions on growth and production the yield of cauliflower, cv.solid snow. Duncan's Multiple Range Test (DMRT) was used to compare means at probability of0.05. Correlation and regression coefficient were also used to evaluate the relationships between studied parameters and time. Vegetative growth parameters that are measured were : plant leaf number ; stem height; stem diameter; plant leaf area; leaf fresh and dry weight; stem dry weight; plant shoot fresh and dry weight. Flowering parameters were : curd fresh and dry weight and curd diameter. The results could be summarized as following : 1. Water chemical analysis showed that irrigation with magnetized treated water had an effect on physical properties, nevertheless, was more or less affected ions components. 2. The use of magnetized treated water in irrigation resulted in an increase in germination percentage of cauliflower seeds cv. Solid snow.The highest germination percentage was obtained from magnetic intensity of 1500 Gauss in both experiments, laboratory and field that reached 71.14 and 65, 62%, respectively on the base of Arc Sin. 3. The use of magnetized treated water in plant irrigation at all the used intensities resulted in an early emerged curd cauliflower by 15 days compared with control treatment plants. 4. 750 gauss magnetized treated water achieved at age of 138 days from transplanting, the highest plant leaf area mean is (4836.2 cm2) with percentage increase of 51.7% compared to control treatment plant leaf area (3188.3 cm2).That effect was reflected on curd weight. 5. 1500 and 2500 Gauss magnetized treated water treatments at earlier ages increased the values of vegetative growth parameters which reflected its effect on flowering growth parameters by shorter time of curd irritation, compared with the effect of 500 - 750 Gauss at earlier ages , which are in spite of its late effects produced at 150 days old from transplanting particularly 750 Gauss the highest mean of curd fresh weight. 6. 750 Gauss magnetized treated water achieved the highest yield reached 22.2 ton/h. which differed from that productivity gained from control treatment plant(9 - 29 ton/h.) with percentage increase of 138.8%. 7. Organic plant manure addition at both quantities(2.5 and 5.0kg/furrow) resulted in an increase in both vegetative and flowering growth parameters compared with untreated plants. 5 kg/furrow treatment produced the highest means compared to control treatment particularly at the age of 138 days in all vegetative growth parameters. 8. The addition of 5 kg/furrow at age of 150 days produced the largest curd fresh weight 918.4 g. and diameter of 17.2 cm which statistically differed to compared plant treatment that produced 506.0 g. and 13.3 cm. for curd fresh weight and diameter at the same age respectively. 9. 5 kg/furrow organic manure addition resulted in a highest productivity of 21.6 ton/h. compared to that of control treatment of 11.9 ton/h. with an increase of 81.5%. 10. Interaction between irrigation water magnetically treated with 750 Gauss and addition of (organic manure with 5 kg/furrow) at the age of150 days resulted in the highest curd fresh weight of 1292.9 g. with curd diameter of 20.3 cm. compared to that plant of control treatment produced curd fresh weight of 292.5 g. and 11.0 cm. diameter. This interaction also produced 30.3 ton/h. for (750 Gauss×5 kg/furrow) compared with the productivity of control treatment plants that gave 6.86 ton/h. with percentage increase of 341.6%

The present study was performed on 366 women (117 miscarriages, 141 pregnant and 108 singles) aged (17 - 35) years old from different hospital in Baghdad. Blood samples were collected from all patients during the period of Oct.2013 until of Jan. 2014. Anti - toxoplasma antibodies in the sera of all samples by using two tests, Latex test (LAT) and ELISA (IgG), (IgM) while, the proinflammatory cytokine were estimated by evaluation of the cytokine such as (IL - 6, IL - 8, TNF - ?). The results were showed that : ? The infection rate of toxoplasmosis by LAT was (41.53%) which was more sensitive than ELISA IgG (36.85%), and miscarried women were diagnosed by higher anti - toxoplasma IgG antibodies 62/117(52.99%), while pregnant result were lower 30/108 (27.78%). ? The most frequent age group of chronic infection with T.gondii was (23 - 28) year in both miscarriage and pregnant women, and represented by 45.16%, 40% respectively. While the most frequent age group for a single woman was (17 - 22) years, and represent 46.511% of the total number of this group.? Seroprevalence of toxoplasmosis by ELISA IgM test revealed low sensitivity in different studied groups 25/366(6.830%), and miscarried women were diagnosed by a highly significant (P ?0.01) percentage of acute toxoplasmosis14/117(11.965%).and The age group of (17 - 22) years old diagnosed high significant (p?0.01) percentage of acute toxoplasmosis in all studied groups.? According to the distribution of infected miscarried women with toxoplasmosis and gestational age by ELISA IgM the result showed that most of miscarriages were occurred at the first trimester which considered high significant (p? 0.01) 8/14(57.42%). While, chronic infected women at the second trimester (4 - 7 month) diagnosed by significantly (P?0.01) higher percentage of miscarried 24/62(38.71%).? The level of pro - infalmmatory cytokine (IL - 6) in acute infected miscarried women with toxoplasmosis distincted with a significantly high increase (P? 0.05) (177.31±12.53 Pg/ml) in comparison to chronic infected one (119.36 ±14.07 Pg/ml).While, chronic infected pregnant women was low significantly (P ?0.01) (48.41± 2.79 Pg/ml) in comparison to acute infected one and other studied groups, ? The acute infected singles was (118.98± 15.68 Pg/ml) higher non - significantly (P?0.05) than chronic infected one (112.65 ± 17.91 Pg/ml) and both disease activity were significantly higher than its level in healthy singles.? The level of TNF - ? in acute infected miscarried women distincted with significantly higher (P?0.05) (97.46 ± 5.37 Pg/ml) in comparison to chronic infected women (69.55 ± 4.58 Pg/ml), Whereas the mean level of TNF - ? in pregnant infected women during acute phase (62.31 ± 3.82 Pg/ml) was significantly (P?0.05) higher than chronic infection (21.42 ±2.74 Pg/ml)? Single infected women showed high significant increase (P?0.05) of TNF - ? level (50.48 ± 7.42 Pg/ml) in comparison to chronic infected one (35.46± 5.36 Pg/ml) and both disease activity scored high significant increase (P?0.05) of TNF - ? in comparison to healthy singles (18.29 ± 1.02 Pg/ml).? Finally, the mean level of IL - 8 in miscarried women with positive infection with T. gondii during acute phase (187.92 ± 15.38 Pg/ml) was significantly (P?0.05) higher than chronic phase of infection (140.57 ± 13.87 Pg/ml).Whereas the mean level of IL - 8 in acute infected pregnant women (110.32 ± 9.13 Pg/ml) was higher significantly (P?0.05) than healthy pregnant (91.49 ± 7.59 Pg/ml) and healthy singles (88.82 ± 5.62 Pg/ml).?

المستخلص: عزلت عشر عزلات من بكتريا Ensifer meliloti من العقد الجذرية لنبات الجت Medicago sativa L. بعد ان جمعت من مناطق مختلفة من محافظة بابل خلال المدة من شهر تشرين الثاني/2012 لغاية شهر شباط/2013. شخصت العزلات جزيئيا بتقنية تفاعل البلمرة السلسلي فضلا عن طرق ال | Ten isolates of Ensifer meliloti were isolated from root nodules of Medicago sativa L. collected from different areas of Babylon province during a period from November - 2012 to February - 2013. The isolates were molecular identified using polymerase chain reaction technique, in addition to traditional methods (morphological and biochemical). All isolates were harboured nodbox and mucR genes and produced cyclic ? - (1, 2) glucans, cellulose fibers and lipopolysaccharide.The ability of isolates to grow at different degrees of pH, temperatures and different concentrations of sodium chloride were tested. It was found that the optimum pH for growing of Em1, Em3, Em4, Em6 and Em8 isolates was pH7, while for the isolates Em2, Em5, Em7, Em9 and Em10 was pH8. The optimum temperature for growing of Em1, Em3, Em5, Em7, Em8 and Em9 isolates was 30?C, while the optimal growth of Em2, Em 4 and Em6 isolates was 35?C, Em10 isolate showed significantly extremism to grow at temperture reached to 45?C. The optimal percentages of NaCl for growing of Em1, Em3, Em4, Em5, Em6, Em8 and Em9 isolates were 2%, for Em7 isolate was 3% and for Em2 and Em10 isolates were 4%. The effect of different degrees of pH on symbiotic properties was studied. Em1 and Em8 isolates that grew at pH6.5 ; all isolates that grew at pH 7, pH 7.5 and pH 8 were able to infect the root hairs of alfalfa plants. The isolates that grew at pH6.5 (except Em1 and Em8 isolates) and all isolates that grew at pH8.5 were failed to infect the root hairs and did not formed nodules and resembled to the control plants (without inoculum).Different concentrations of NaCl on symbiosis was studied, it was found that all isolates that grew at 2% and Em2 and Em10 isolates that grew at 3% formed nodule, while Em1, Em3, Em4, Em5, Em6, Em7, Em8 and Em9 isolates that grew at 3% and all isolates that grew at 4%, 5% and 6% did not elicited nodules on the roots of alfalfa plant. Light microscopic observations of root hairs inoculated with Ensifer meliloti isolates showed the root hair deformations like curling, waviness, swelling and formation of shepherd`s crook and infection thread. These consequent changes lead to emerge the mature nodules having five distinct zones viz., distal meristematic, infection, inter, nitrogen - fixing and proximal senescence zones.The gel electrophoresis results of plasmid DNA of isolates showed that these isolates harboured two megaplasmids. When the isolates exposed to extreme factors like pH, temperture and NaCl, it was found that the isolates lost these plasmids and its ability to elicite the nodules and failed to fix the nitrogen. This study showed that the nitrogen fixing bacteria had essential role to support the plant growth and increase their productivity, and recommended to use the isolate Em10 as example for biofertilizers and the best alternative to the chemical fertilizers

المستخلص: تم اختبار قابلية عشرة عزلات للعفن Aspergillus fumigatus على انتاج الغليوتوكسين بوساطة تخمرات الحالة الصلبة وباستخدام الرز كوسط زرعي (ركيزة). اشارت نتائج الغربلة ان العزلة AF - 5 كانت هي الافضل واعطت اعلى انتاجية.كانت الظروف المثلى لانتاج السم على وسط الر | The ability of Ten Aspergillus fumigatus isolates for gliotoxin production were screened by solid state fermentation (SSF) using rice medium as substrate. The results indicated that, the AF - 5 isolate was the highest gliotoxin producer.The optimum conditions for gliotoxin production by AF - 5 isolate on rice medium were : - inoculum size 6×106 spores, moisturizing ratio (5 : 1) (w : v) with distilled water and incubation at 37 ?C for 10 days. Gliotoxin was purified from crude extract of AF - 5 isolate after production under the optimum conditions using solid state fermentation SSF. Purification of gliotoxin was achieved by two steps including : filtration and solid phase extraction. These processes were accessed to remove debris from crude extract and gives pure gliotoxin. The gliotoxin concentration was (122.6 ppm), which was detected by Thin layer Chromatography and High Performance Liquid Chromatography.The result of cytotoxicity effect of both purified extract and standard gliotoxin on human lymphocytes with exposure time of 24 hours at four different concentrations 25, 50, 100 and 200 ppb showed growth inhibition percentage 21, 39.10, 61.99, 87.45% and 17.89, 34.92, 58.34, and 85.22% respectively. The cytotoxicity effects have been done using conversion of the MTT to MTT formazan. After DNA was extracted from lymphocyte treated with toxin and analyzed by electrophoresis on a 1% agarose gel, gliotoxin appeared to have ability to damage the DNA. Results showed that both growth inhibition and DNA damage were increased gradually with the increasing of gliotoxin concentration.

المستخلص: يتعرض الحليب للعديد من الملوثات الفيزيائية والكيميائية والبيولوجية وذلك بسبب طرق الانتاج واسلوب النقل وعمليات التسويق ومن هذه الملوثات المعادن الثقيلة والرقم الهيدروجيني ودرجة الحرارة والبكتيريا. وقد صممت الدراسة الحالية لفحص عينات للحليب الخام التي جمعت | Milk is subjected to various physical, chemical and biological pollutants duo to producing, transporting and marketing processes such as certain heavy metals, pH, temperature and bacteria. The current study was designed to examine fresh milk samples were collected randomelly at early morning from six different locations at a rate of once each month during study period which commenced in October 2013 and ended in march 2014 and powder milk brands which were examined again for six months as in case of fresh milk where these milk brands were collected from local markets each month. The results of heavy metals showed that : • The investigation of Lead content in raw milk revealed that the highest mean value (1.801±0.311 ppm) was scored in Abo - Ghraib sample and the lowest mean value (0.941±0.104 ppm) was observed in Ghazaliya sample. For the Cadmium content in raw milk that the highest mean value (1.532±0.124 ppm) was found in Abo - Ghraib sample and the lowest mean value (0.063±0.044 ppm) was found in Fal'loga. The Copper content in raw milk also investigated and resulted the highest mean value was (0.931±0.092 ppm) in Azizia milk sample and almost similar value (0.931±0.301 ppm) was found in Madain sample while the lowest mean value was (0.308±0.029 ppm) in Fal'loiga sample. The highest mean value of Potassium in raw milk was recorded in two samples in Azizia (9718.8±246.6 ppm) and (9718.3±482.2 ppm) in Abo - Ghraib but the lowest mean value (4156.3±268.3 ppm) was recorded in Essaouira. Regarding Sodium content in raw milk, the results have found that the highest mean value was (2968.8±312.2 ppm) in Essaouira sample while the lowest mean value was (1432.5±156.8 ppm) in Abo - Ghraib. The Chloride content in raw milk samples, the highest mean value was (3053.0±128.6 ppm) recorded in Fal'loga sample and the lowest mean value was (639.0±198.4 ppm) was found in Azizia sample. Analysis of variance of these data showed significant effects (P?0.001) of both sampling sites and collecting months on milk (pb, Cd, K, Na and Cl) contents while analysis of variance of these data reveals no significant impact of sites on milk Cu content (P> 0.05) where no differences were observed between mean value of different collecting sites but shows highly significant (P? 0.001) effects of collecting months.• While powder milk has shown that the highest mean values of Lead (1.225±0.052 ppm) were found in Al - Mudhish brand and the lowest mean value (0.088±0.002 ppm) was detected in Anchor. The highest mean Cd value was (0.184±0.005 ppm) in Nido brand and the lowest mean value was (0.069±0.003 ppm) in Altunsa sample. While the highest mean value of Copper was (1.656±0.254 ppm) in Dielac powder brand and Anchor milk brand had the lowest copper mean value which was (0.767±0.014 ppm). The concentration of Potassium was (9625.0±462.9 ppm) which is the highest recorded in Dielac milk sample and the lowest mean value (3356.8±225.6 ppm) was found in Al - Marai milk sample. While the highest average of Sodium was (2625.0±342.6 ppm) scord in Dielac brand and the lowest average was (1745.0±338.4 ppm) recorded in Al - Marai sample. The highest mean value of Chloride (193.0±41.0 ppm) was recorded in Nido milk brand and the lowest mean value (122.7±22.2 ppm) was found in Altunsa milk sample. However, analysis of variance shows significant differences (P?0.001) between examined milk brands while no such differences were found between these brands (P>0.05) regarding collecting months.From the above results, it seems that the highest content of (Pb, Cd and Cu) are higher than those of standards of the International Dairy Federation (IDF) while contents of (K, Na and Cl) are within the standard requirement according to National Research Council (NRC).Microbial tests of raw milk samples were positive for bacterial growth, as different bacterial species were observed such as Lactobacilli spp. 63.8%, Streptococcus spp. 61.1%, Staphylococcus aureus 44.4%, Escheritia coli 88.8%, Bacillus spp. 72.2%, Salmonella typhi 72.2%, Staphylococcus epidermidis 30.5%, Pseudomonas spp. 47.2%, Micrococcus spp 27.7%, Clostiridia spp. 66.6%, Enterococci spp. 11.1% and K. pneumonia 75% from bacterial contamination of raw milk samples.However, only (11.1%) of the total collected samples of raw milk were suitable for human consumption and (88.9%) unsuitable, indicating that the source of infection or contamination of milk may be due to the animal health, human handler and the environmental factors, e.g., contaminated vessels, polluted water, flies and dust, etc… Obviously, bacterial contamination test of powder milk samples was carried out and negative results were obtained. However, it seems clearly that the opportunity of finding bacterial contamination in powder milk samples may be very rare since milk powder is produced in well designed and modern techniques. Nevertheless, a single bacterial contamination test has indicated to a positive growth of Staphylococcus aureus colonies.

المستخلص: 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.

المستخلص: The current study had been carried out from January 2013 to July 2013 in medical laboratory researches - Kirkuk Faculty of Medicine. A total of 310 stool samples have been collected from children suffering from liquid diarrhea, their ages are from below one year to 12 years; six different laboratory diagnostic methods have been applied for detecting Giardia lamblia and other intestinal parasites. For microscopy diagnosis; direct wet double prepartions, zinc sulphate flotation are used. While immunological methods involve; Enzyme Linked Immuno - Sorbent Assay, corpo - antigen (ELISA), Direct Fluorescent Assay (DFA) and Lateral immune - chromatography assay (Triage panel). Giardia genome amplification is done using conventional Polymerase Chain Reaction (PCR) single step procedure by using of mixed primers of Giardia assemblages A1, A2 and B. The total rate of intestinal parasitic infection is 51.93 % distributed in 161 stool samples. This rate involve high frequency of protozoan infection in 132 (42.58 %) compare to 29 (9.35 %) for helminthes, P<0.05. More common intestinal protozoan parasites were Giardia lamblia 63(20.32 %) followed by Blastocyst hominis, Cryptosporidium parvum, Entamoeba coli, Entamoeba histolytica, Iodomoeba butschili, Endolimax nana and Balantidium coli with the rates : 6.77%, 6.45%, 4.18 %, 2.58 %, 1.29 %, 0.64 % and 0.32 % receptively. Concerning intestinal helminthic infection, high number and rate 23(7.41 %) was with Hymenolepis nana is compare with 1(0.32 %) record for Ancylostoma duodenale.According to gender high rate of giardiasis is recorded among males than in females, conversely to high rate of other intestinal parasites among female than in males P<0.05. Statistically relationship between Giardia distribution and ages are not significant P>0.05. Giardia co - existence are highly detected with Balstocystis hominis, and Cryptosporidium parvum total Giardia mixed parasitic infection rate 8.06 % is lower than12.23 %of pure Giardia lamblia infection, P>0.05. Regarding Giardia lamblia detecting according to laboratory methods; high rate of giardiasis 22.29% is reported by using PCR technique, followed by 20, 23 % by using direct wet preparation technique, P<0.05.The efficacy of laboratory methods for detecting Giardia stages are reduced; the following rates 19.35%, 19.03%, 17.74% and 14.51% obtained by using ELISA, DFA, flotationand lateral immuno - chromatography assay (Triage) respectively, P<0.05. Also statistical analysis reveals significance of PCR sensitivity, specificity, and accuracy in detecting giardiasis than other laboratory methods. Negative predictive values NPV in relation to type of laboratory methods are high, but statistically they are not significant, controversy to positive predictive value PPV that are significant. The efficacy of Triage panel is high for detecting giardiasis 14.45 % as compare with 4.5 % and 3.5 % for detecting Cryptosporidium parvum oocysts and Entamoeba histolytica respectively P<0.05 %. Considering the application of double direct wet preparations, the results of using this method are beneficial for detecting protozoan and helminthic parasites.

The study has been conducted on (105) patients with asthma whose ages from (20) to (69) years. (20) of them are males and (85) are females, and (110) are healthy with no infection of asthma or any sickness of respiratory system as a control group of the same ages, (60) of these are males and (50) are females. Blood samples have been collected from both groups in ampoules with EDTA and stored under temperature ( - 20) until they are used in getting the DNA from the groups. The genes GSTTI, GSTMI, and Albumin have been enlarged as internal control employing Polymerase chain Reaction (PCR). Some dangerous aspects of this disease have been investigated, the results showed that the disease in the urban areas (85. 71 %) higher than it rural areas, and Asthma among females is (80. 95%) higher than males. The results also indicated that asthma in ages (50 - 59) is more than other categories; it is (34.28%). The majority of patients are smokers with (63.80%). The study revealed that (73.33 %) of the patients have a family history with the disease while (26.66 %) have not. Statistical analysis showed that the loss of the gene GSTM1 is about three times in the patients more than the case in the control group. (OR=2.90) , while the loss of the gene GSTT1 is five fold more than it compared to the control group (OR= 5.55). The results indicated a significant effect of the loss of the two genes in having asthma in the urban and rural areas, it is six times and a half larger in the urban areas compared to the control group of the same area. Asthma probability is ten times more in the case of the loss of both genes in the rural areas compared to the control group in the same area. And no significant difference has been discovered when gene patterns of patients in both areas. The results also indicated that the probability of having asthma in male patients is two times and a half as many as it in the females when the gene GSTM1 is lost compared to the control group. While the same probability is eleven times in the case of the loss of both genes in the females as many as it the control group. The loss of Missing the gene GSTT1 is three times in the male patients and five times in the females compared to the two control groups. The results indicated significant differences when gene patterns of males and females are compared in the case of the loss of both genes. The statistical analysis indicated that the loss of both genes in the smoker patients contributes 17 fold in the probability of having the disease compared to the control group. While the probability increases four times approximately in the nonsmokers when the gene GSTM1 is lost compared to the control group (OR=3.77; 95% C1=1.69 - 8.407). No difference has been noticed in the gene patterns of the smoker and nonsmoker patients. The results indicated that the loss of both genes has been in all the age categories. No significant differences have been noticed among the gene patterns between the patients of less and those who are more than 50 years. Asthma probability has been found 7.77 times more in the case of the loss of both genes in the patients who have a family disease history compared with the control group. The asthma probability is twice when the gene GSTM1 is lost in those patients who do not have a family history disease compared to the control group. Upon comparing the gene patterns of patients according to the family disease history, there has been an effect of the loss of both genes and having a family disease history on the probability of asthma, it is almost six times when both genes are lost. The results indicated that the probability increases three times in the loss of the gene GSTT1 in the educated patients compared to control group. The probability also increases seven times when both genes are lost in the uneducated patients compared to the control group. When comparing the gene patterns of patients according to levels of education, significant differences between the educated an uneducated have been approximately twice in the loss of the gene GSTT1.

A total of 360 suspected cases were collected from Center Health laboratory/Al - Hakeem Hospital, and AL - Sadder medical city in AL - Najaf city, during the period from January (2013) to August (2013). Only 76 were seropositive hepatitis B (55 males and 21 females with age ranging 11 - 72 years).In addition, 15 healthy individuals without any evidence of chronic inflammatory disease were depended on the control group, age ranging 21 - 50 years.Blood samples were collected from patients and healthy controls were tested for HBsAg and Anti - HBc Ab using Enzyme Linked Immunosorbent Assay (ELISA) technique to investigate hepatitis B seropositive and chronic hepatitis B respectively. For investigated AIH disease was performed depending on the Line Immune Assay technique. While for detection CMV were initially identified by serological technique (ELISA, MiniVIDAS) to detect anti - CMV IgM and anti - CMV IgG; then confirmed employment molecular technique using Real Time Polymerase Chain Reaction for the detection the presence of DNA of CMV. Samples were collected from patients and control to estimation immunological level (C3, C4, IL - 10 & TFN - ?) by using ELISA and radial immunodiffusion method.The results showed that 76 HBsAg seropositive in all age groups but the age group 44 - 54 year revealed high significance (p<0.05) than other age groups. While 35 out of 76 seropositive with HBc Ab, the age group 55 - 65 years showed high significance (p<0.05) than other age groups, and males more infection than females. The result also revealed that the AIH disease was 5 out of 76 patients infected with Type 1 AIH. Included 2(40%) have demonstrated the infection HBsAg positive with reactivation CMV While 3(60%) infected with HBsAg only.The results showed that 68 out of the 76 samples were positive for anti - CMV IgG antibodies, and 4(5.26%) samples were positive for anti - CMV IgM. While the MiniVIDAS test results showed 73 out of the 76 samples was positive for anti - CMV IgG antibodies. 2(2.6%) were positive for anti - CMV IgM antibodies. The results of the Real - Time PCR revealed that DNA of CMV were detected in 23 out of 76 patients were found in all age groups with viral loads ranging from (0.24 - 1730000) Copies/ml, and the results of controls group in Real - Time PCR were CMV negative. The results of cytokines (TNF - ?) showed a high significance (P<0.05) elevation in the serum of all patients than control (419.3 ± 27.8) pg/ml, and the results that AIH showed increase in cytokine level was (1218.2±44) pg/ml than other patients. Whereas chronic hepatitis B patients recorded high significance (P<0.05) in level (IL - 10) was (901.5±22.2) pg/ml than other patients and control (373 ±30.3) pg/ml. According to sex no - significance difference between males and females in results of cytokines profile (IL - 10, TNF?). Complement fraction C3 decreased in all patients compared to those healthy control, while the AIH patient recorded high significance (P<0.05) 142.2±8 mg/dI than the other patients. In regard to C4 was revealed normal level in all patients compared with control groups while in the AIH revealed high significance (P<0.05) was 41.7±5.1 mg/dI compared with other patients and no - significance difference (P<0.0) between males and females in level of C3and C4.The overall finding results showed that the activation cytomegalovirus with hepatitis B virus Contribute to the induction of AIH and cause immune suppressor for them by increase and decrease many immune factors.

These fungi were related to 23 species or isolates, where Aspergillus spp. prevailed over all others (11 species) with CF of 14% for all Aspergilli, Aspergillusniger and Aspergillusflavus showed the highest CF 7.2% and 3% respectively, other Aspergilli represented Aspergillusparvulus (CF 1.6%), Aspergilluscandidus (0.4%), Aspergillusraperi, Aspergillusclavatus, Aspergillusglaucus, Aspergillusornatus, Aspergillussclerotioniger, Aspergillusterreus and Aspergilluswentii were all showed CF of 0.2%.Other isolates fungi from leaves fragments were four morphologically different isolates of Penicillium with 0.4% CF for each. Additionaly, isolates of Cladosporium sp. (2%) and Cladosporiumcladosporoides (0.4%), as well as Cunninghamella sp., Drechsleraaustraliensis, Alternariaraphani, which showed 0.2% CF for each, Paecilomyces variotii (0.6|%), and different isolates of sterile fungi (White and Hyaline colonies) were also obtained. - Study the antagonistic activity of isolated endophytes using dual culture method against five plant pathogenic fungi(Fusarium oxysporum, Fusarium graminearum, Fusarium sp., Macrophomina phaseolinaandRhizoctonia solani)taking into account the percentage of inhibition of pathogenic fungi, results revealed variation of antagonistic activities between endophytes and pathogens. Different cases of antagonism were also appeared ranged from mycoparasitism of the endophytes on pathogens or vice versa, to competition between the two fungi and to the appearance of inhibition zone between them, this result may indicates the affinity of using some isolated endophytes in biological control applications against or controling fungal plant diseases. - Effect of ethylacetate extracts of culture broth of active endophytes shown in the last experiment against two bactria E.coli, S.aureus and the yeast Candida albicans using disc diffusion method, where filter paper discs were imprignated with different concentrations of fungal broth extracts. Results showed variation of inhibitory activity against bacteria with different endophytes, bacteria and conc. of the extract. Regarding the effect onC.albicans and filamentous fungi, most fungal broth extracts showed no inhibitory activity against yeast and no extract as well showed inhibitory activity on filamentous fungi. These results give indication thatbroth extracts contain antibacterial compounds. - Addition of 20% crude fungal broth of some endophytes to the culture medium showed significant inhibitory activity against filamentous fungi which did not respond to broth extracts, percentage of inhibition ranged between 0 - 77.08% and maximum inhibitory activity was shown by Penicillium sp. Isolate. These results give indication that some of crude filtrates contain antifungal compounds. - Analysis of broth extracts of some endophytes using TLC technique showed the content of extract of number of UV illuminated spots isolated on TLC pates having different Rf values, Bioautography showed inhibitory activity of some of these isolated spots against E.coli, S.aureus and the Filamentous fungus F.oxysporum. - Testing the extracellular enzymes activities of isolated endophyles on solid media, enzymes included amylase, lipase, pectinase, laccase, cellulase and protease showed variation in secretion of these enzymes, as well as, no endophytes showed the affinity of secreting all tested enzymes. Results also showed the high affinity of some endpohytes to secrete enzymes that could be use in multiple important applications after separation andcharacterizationof these enzymes.

المستخلص: To evaluate the anti - hyperglycaemic potent of thymoquinone from Nigella sativa seed in streptozotocin - induced diabetic male rats, the present study has been carried out at the College of Education, Al - Qadisiya University during the period extended from April, 15, 2012 to December, 15, 2012. mRNA expression level of Reg3a, InsI, InsII, PDX1, Pax6, NeuroD1, and MafA genes have been evaluated in pancreatic tissues as well. Sixty five adult male rats (aged 56 days and weighted 138±8.8g) have been used in the present study. Diabetes has been inducted in 52 male rats by injection of single dose of streptozotocin (60 mg/ kg, b.w., i.p.). Diabetes mellitus has been confirmed by blood glucose concentration (to be more than 200 mg/ dl). Intact and streptozotocin - induced diabetic male rats have been assigned to five equal groups (13 per each); Intact (C) and non treated diabetic (DM) rats have been injected with normal saline (100?l, sc) anddrenched with drinking water daily for 42 days. Thymoquinone treated diabetic rats (TQ50 and TQ100) have been injected with normal saline (100?l, sc) and drenched with thymoquinone suspention (50 and 100 mg/ kg, b.w., respectively) daily for 42 days. Insulin treated diabetic rats were injected with insulin (4 IU, sc) and drenched with drinking water daily for 42 days. Body weights were registered daily during the experiment. All overnight fasted animals were sacrificed after general anesthesia by combination of xylazine and ketamine (10 mg and 90 mg/kg, ip, respectively). Blood samples was collected from abdominal vein for determination of serum glucose and insulin concentrations. Samples from pancreatic tissues in all groups have been quickly removed, dipped in liquid nitrogen for RNA extraction and molecular study. Other pancreatic tissues were fixed in formalin forhistopathological and immunohistochemical study. The results demonstrated significant decrease in body weight gain of untreated diabetic (DM) and insulin treated diabetic (DMI) groups as compared with that of intact control (C) and thymoquinone treated diabetic (TQ50 and TQ100) groups, started from the fourth day of experiment, which showed insignificant differences when compared with each other. While the lowest body weight gain has been registered in DM group.Results of serum glucose concentrations referred to significant elevation in diabetic groups compared with intact control. In comparison between the diabetic groups, glucose concentration revealed significant decrease in thymoquinone and insulin treated rats (TQ50, TQ100, and DMI) compared with untreated diabetic rats (DMI). on the other hand, insulin treated males (DMI) and thymoquinone treated males (TQ50 and TQ100) recorded no significant difference in serum insulin concentration when compared witheach other but they were significantly lower than that of intact control male rats (C), but the average means of these four groups were significantly higher than that of non - treated diabetic male rats (DM).Quantification analysis results of gene expression, performed by real - time RT - PCR, revealed that treatment with thymoquinone caused significant increase of mRNA expression levels of Reg3a, InsI, InsII, PDX1, Pax6, NeuroD1 and MafA genes during the studied period. Histological findings of thymoquinone treated pancreases revealed normal cellularity of islets of Langerhans and normal exocrine tissue except few congestion in it, whereas those obtained from non treated diabetic rats showed complet impairment of some islands and highly destructed of others. Normal hepatic architecture with the appearance of radiating shape around the central vein, has been shown in the section obtained from thymoquinone treated diabetic rats except few congestion, obvious regeneration and mitotic division in the nuclei of hepatocytes. Sections obtained from non treated diabetic male rats showed sever congestion, large thrombi in the hepatic tissue, and loss of hepatic architecture with sever hemorrhage, degeneration in hepatocytes, and dilation of sinusoids. Section obtained from kidneys of thymoquinone treated diabetic rats reveales normal renal convoluted tubules with normal epithelium of the tubules and high cellularity of glomeruli. Whearas those obtained non treated diabetic rat revealed dilation of renal convoluted tubules with necrosis in the epithelium of the tubules and sever hemorrhage in the renal tissue. Immunohistochemical results revealed that male rats drenched with thymoquinone registered higher scores of positive cells and intensity of staining compared with other diabetic (DM and I) groups. Hisological sections obtained from pancreases of control male rats showed actively stained islets of Langerhan's by immunohistochemistry with actively stained populations of beta, alpha, and delta cells, whereas those obtained from pancreases of non treated diabetic male rats showed damage of most cell populations and negatively stained for the few remaining beta cells. on the other hand, section obtained from pancreases of diabetic male rats treated with thymoquinone showed actively stained islets of Langerhan's by immunohistochemistry with actively stained populations of beta, alpha, and delta cells. While those obtained from pancreases of diabetic male rats treated with insulin, in the same stages of experiment, showed negatively stained beta cells and other cells of islets of Langerhan's. Histopathological findingsrevealed moderate improvement of pancreatic changes shown in both exocrine and endocrine (Islands of Langerhan's) parts. It can be concluded that drenching of 50 or 100 mg/ kg, bw, of thymoquinone from Nigella sativa seed has potent hypoglycemic effect in experimentally - induced diabetic mature male rats. As well as its positive role in elevating the expression level of Reg3a, InsI, InsII, PDX1, Pax6, NeuroD1

المستخلص: The present study has been carried out at the department of biology, College of Education, Al - Qadisiya University, Iraq, to investigate the immunological localization of transforming growth factors beta (inhibins and activins) subunits during immature and mature periods and its involvement in male reproductive physiology of rats.At pre - pubertal stage, five male rats of 25, 30, 35, 40, and 45 days old, and at post - pubertal stage, five male rats of 55, 60, 65, 70, and 75 days old have been used in the present study. Experimental animals have been anesthetized and blood samples were obtained from abdominal vein for assesment of activin - A, inhibin - B, FSH, LH, testosterone, and estrogen, testis volumes were measured for each age period. Testes, epididymis, prostate and seminal vesicle, were obtained for molecular and immunohistochemical studyto investigate the expression levels of Inha, Inhba, and Inhbb genes using qRT - PCR and immunohistochemical technique.The present study demonstrated gradual increase of testis volume throughout the male rat life in parallel with the increase of serum inhibin - B and testosterone concentrations. Serum activin - A concentration increased significantly at 30 and 40 day periods. Throughout the post - pubertal stage, activin - A concentration gradually decreased. Serum inhibin - B concentrations gradually decreased at the pre - pubertal stage. Post - pubertal stage registered gradual increase. At 25, 30, and 35 day periods, serum FSH level registered no significant changes, whereas 40 day period recorded significant increase then decreased at 45 day period. Throughout the post - pubertal period, the level of FSH concentrations continued in gradual decrease. At 25, 30, 35, and 40 day periods, serum LH and testosterone levels showed no significant differences, whereas 45 day period recorded significant increase. Postpubertal period showed gradual significant increase. Serum estradiol concentration decreased gradually at the pre - pubertal stage and continued in decrement at the post - pubertal stage.The expression level of Inha gene in testis decreased as the age progress until 40 day period, and then slightly increased at 45 day period. At 55 day period, the expression significantly increased. At 60 and 65 periods, the levels recorded no increase, but 70 and 75 day periods recorded significant increase. The expression level of Inhba gene increased significantly as the age progress at the pre - pubertal stage, where the highest level was recorded at 45 day. At 55, 60, and 65 day periods, the highest expression level has been recorded, thenafter, the levels decreased at 70 and 75 day periods. The expression level of Inhbb gene increased significantly at 30, 35, 40, and 45 day periods of the pre - pubertal stage. At 55 and 60 day periods, no significant difference was recorded compared with 45 day period. At 65 day period, the highest level was recorded, thenafter, the levels decreased at 70 and 75 day periods. The expression level of Inha gene in epididymis recorded no significant difference at all periods of the pre - pubertal stage, but the post - pubertal stage showed gradual significant increase as age progressed. The expression level of Inhba gene recorded no difference at 25, 30, 35, and 40 day periods, but it was significantly higher at 45 day period. The levels at 55, 60, and 65 day periods recorded no significant difference when compared with each other or with 45 day period. Significant increase has been recorded at 70 and 75 day periods. The expression level of Inhbb gene increased significantly at 30 and 35 but it decreased at 40 day period, then it showed further increase at 45 day period. At 55, 60, 65, and 70 day periods, also increased but the highest expression level was recorded at 75 day period.The expression level of Inha, Inhba, Inhbb genes in prostate recorded no significant difference at all periods of the pre - pubertal stage, but the postpubertal stage showed significant increase at all periods.The expression level of Inha and Inhba genes in seminal vesicle recorded no significant difference at 25, 30, 35, and 40 day periods and significant increase at 45 day period. The 55, 60, and 65 day periods recorded no significant difference when compared with each other but significant increase has been recorded at 70 and 75 day periods. The expression level of Inhbb gene recorded no significant difference at 25, 30, and 35 day periods, but it increased as the age progressed, whereas the levels showed no significant difference at all periods of the post - pubertal stage, but they were significantly higher than that recorded at the pre - pubertal stage. The results of immunohistochemical study demonstrated positive immunostaining for inhibin - ? subunit in Sertoli cells and primary spermatocyte and no staining in Leydig cells of pre - pubertal rat testis, whereas post - pubertal testis showed positive immunostaining in Sertoli cells, Leydig cells and primary spermatocyte at 55 day period and positive immunostaining in Sertoli cells, Leydig cells, and spermatogonia at 60 day period. There was positive immunostaining in Sertoli cells, Leydig cells, spermatogonia, primary spermatocyte and spermatid at 65, 70, and 75 day periods. At 25 and 30 day periods of pre - pubertal stage, rat epididymis showed moderate positive immunostaining in epithelial cells, but strong positive staining in epithelial cells has been shown at 35, 40, and 45 day periods and at all periods of the post - pubertal stages. The result expressed positive immunostaining in the epithelial cells of the pre - pubertal rat prostate and strong positive immunostaining at the post - pubertal stage. on the otherhand both, pre - pubertal and post - pubertal rat seminal vesicle showed strong positive immunostaining in epithelial cells. Weak positive immunostaining of Inhba has been observed in the primary spermatocyte and no staining in Sertoli cells and Leydig cells in the prepubertal rat testis and at 55 day period of the post - pubertal rat testis, and no staining in Sertoli cells, Leydig cells and spermatogenic cells at 60, 65, 70, and 75 day periods. Moreover there was positive immunostaining in epithelial cells in both the pre - pubertal and post - pubertal rat epididymis and prostate. In the post - pubertal stage, rat prostate showed strong positive mmunostaining in epithelial cells. No staining was observed in epithelial cells in both the prepubertal and post - pubertal rat seminal vesicle. The pre - pubertal rat testis showed strong immunostaining for Inhbb subunit in Sertoli cells, Leydig cells and primary spermatocyte, in adittion to spermatid in post - pubertal rat testis. Strong positive immunostaining in epithelial cells of the pre - pubertal rat epididymis at 25 and 30 day periods was expressed, but moderate positive immunostaining in epithelial cells of prepubertalrat epididymis was observed at 35, 40, and 45 day periods and postpubertal rat epididymis. However Inhbb subunit in both pre - pubertal and postpubertal rat prostate showed positive immunostaining in epithelial cells. There was positive immunostaining in epithelial cells in the pre - pubertal rat seminal vesicle at 25, 30, 35, and 40 day periods, and strong positive immunostaining at 45 day period and post - pubertal stage.It could be concluded that serum inhibin - B has positive correlation with testis volum and testosterone concentration at pre - and post - pubertal stages, and positive correlation with FSH and LH concentrations at pre - pubertal but negative partial correlation at post - pubertal stage. There was relationship between serum inhibin and activin concentration and fold changes of Inha, Inhba, and Inhbb genes in testis, epididymis, prostate, and seminal vesicle tissues at all periods of the study. Positive immunostaining for inhibin ? - and ?B - subunits, but not for ?A - subunit has been shown in testis cells and epithelial cells of seminal vesicle, positive immunostaining for inhibin ?, ?A, and ?B subunits in the epididymis and prostate

Air temperature at sampling time was varied from 16°C to 42°C and from 10°C to 34°C, for water temperature at sampling time also. The results of pH values were within the allowable limits, ranging from 7.1in autumn to 8.1 in summer. For EC, the highest value recorded for raw water was in winter with 1338 µs/cm, while the lowest value was in spring with 920 µs/cm. The highest value recorded for drinking water was again in winter with 1330 µs/cm, and the lowest value was 910µs/cm in spring also. The highest value of turbidity recorded for raw water was in winter with 89 NTU and the lowest value was in spring with 26 NTU, while the highest mean value recorded for drinking water was 20 NTU again in winter and the lowest value was 1 NTU in spring. The study showed that the results of TDS values ware ranged from 622 mg/L in spring to 1024mg/L in winter. The highest value of residual chlorine was recorded in summer with 4.5 mg/L; the lowest value was zero mg/L in some of the farthest points of the plants. For sulfates, values were ranged from 289 mg/L in spring to 498.4 mg/L in winter. All the recorded values of chlorides ions for all water samples were within the allowable limits, its values ranged from 98mg/L in summer to156.3 mg/L in winter. For total hardness, the values were exceeding 500mg/L and allowable limits for Iraqi standard criteria. The highest value recorded for raw water was in winter with 520 mg/L and the lowest value was in summer with 351 mg/L, while the highest value recorded for drinking water was again in winter with 516mg/L and the lowest value was 337 mg/L in summer also. For calcium values ranged from 75 mg/L in summer to 135 mg/L in winter. The results of this study showed high levels of lead, cadmium and aluminum in most water samples which collected during study period compared with those that exceeded the acceptable limits provided from the quality control unit and which are considered to have adverse effects on health. For lead, values were found to vary from 0.0030 mg/l in summer to 0.16 mg/l in winter (higher acceptable limits is 0.01 mg/L). While in case of cadmium the values lied between 0.0014 mg/l in winter and 0.015 mg/l in summer (higher acceptable range is 0.0030). However, for aluminum these data were ranged from 0.0062 mg/l in raw water during spring to 0.29 mg/l in drinking water during spring also (higher acceptable range is 0.2). The current results showed an increased in the number of autotrophic bacteria, total coliform, fecal coliform, fecal streptococci, and E. coli during winter season in most study locations as compared to those of the other seasons for both water plants raw and drinking water while the FS values were less than those of other bacterial types for both water plants. The Total plat count results of drinking water were exceed 100 cell/ml, the allowable limit for drinking water, for some samples of both water plants. on the other hand, the TC, FC and E. coli exceeded zero cell/100ml, the allowable limits for drinking water, in many drinking water samples for both water plants

المستخلص: تم جمع خمسين عينة سريرية من قشع مرضى مصابين بذات الرئـــة. وذلك للمدة من تشرين الثاني 2013 ولغاية ايار 2013 من مستشفى ابن البلدي ومستشفى بغداد وذلك لعزل وتشخيص بكتريا Klebsiella pneumoniae التي تعد احدى العوامل المهمة المسببة لاصابات الرئة. واخضعت عينات | Fifty clinical samples collected from sputum of patients who suffered from pneumoniae in Ibn - Balady hospital and the hospital in Baghdad city during the period from November 2012 to May 2013 for the isolation and identification of Klebsiella pneumoniae, one of the important causative agents of infection occurs in the lungs. Sputum samples were subjects to the standard laboratory procedures including identification by biochemical test and VIETK system. The results showed 15 isolates were revealed as Klebsiella Spp, only 10 isolates represented K.pneumoniae, The isolates were examined to produce extracellular toxic complex (ETC) it was found that the isolate named K2 was the higher production. Two method for purification the extracellular toxic complex (ETC) were used, first Aqueous two phase systems, In this method polymer - salt aqueous two phase system was evaluated in crude extract of K. pneumoniae at varying concentration of Dextran T - 150 with 20% with polyvinyl pyrrolidone to final rate (1 : 1) (wt : wt) with 0.2M sodium sulphate. The results showed the best concentration dilution sample given as (4.25 : 0.75) with protein concentration (97.173 mg/ml) which contained ETC in the lower layer and the mice died within 4 hours, while the second method performed by using two step column chromatography, ion exchange DEAE - Cellulose and gel filtration (Sepharose - 4B). In the first step sample given lethal activity by injection to the mice after six hours with protein concentration (55mg/ml), More purification by the second step animal died after 3hours with contain protein (27.75mg/ml). Furthermore, the results of the extracellular toxic complex characterization proved that molecular weight was 39810 Dalton determined through Gel - filtration chromatography using Sepharose 6B gel. The LD50 value of purified toxin was calculated, and the result was (6.52 mg/ml) of toxin.This quantity was found effective to cause killing of 50% of the total toxin treated animals. The biological effect of purified toxin of K. pneumoniae K2 have been examined in vivo by injection of dose (0.5 ml) of purified ETC toxin that contain (10.875 mg/ml ) protein. The final part of the study involved the histopathological changes were noted, abundant mononuclear infiltrate of inflammatory cells with necrosis of lung parenchyma. The second group of mice injected with (0.05 ml of ETC) that contain protein (1.085mg/ml) represented as sub lethal dose Histopathological changes were noted showing near of the normal appearance of alveoli and alveolar space, with presence of congestion of blood vessels. The third group of mice inject with (0.5 ml from Tris - base buffer only) represented control showed normal alveoli and alveolar space with presence of bronchial. In the immunological test the sample ETC examined with ELISA and given IgG titer (189.68+50.70 ng/ml) compared with control (46.78+12.45). This titer of IgG tested with Double immune diffusion assay and gave precipitation line with antigen compared with control.

المستخلص: In recent years, foods produced by genetic engineering technology have been on the world food markets. The biosafety aspects, regulations, and labeling for these foods are still contentious issues in most countries. Thus detection and quantificationof GMOs play crucial role for developing regulations on GM foods.In this study, eighty six non - labeled rice samples from different locals and exported market were analyzed to detect the genetic modification using a DNA based detectionvmethods as, conventional Polymerase chain reaction (PCR), and Real time PCR (RTPCR).The DNA rice samples were extracted by manual C - hexadecyl - Trimethyl - Ammonium - Bromide (CTAB) method and wizard kit method. The result revealed that DNA yield by the two methods is comparable. Rice DNA tends to be of a higher concentration when purified with the CTAB method; however, this particular DNA is more easily to amplify, the optical density (OD) was recorded 1.70 - 1.98 and the concentration of DNA quantified by fluorometer DNA rice samples, ranged from 11 to 50.5 ?g/?l. The DNA rice sample has also been used successfully with the Wizard Genomic DNA Purification Kit, and showed varieties in quality, the OD was recorded 1.65 - 1.95, and the concentration between 4.7 - 43.8 ?g/?l.The rice specific gene (sps gene) was detected by PCR. The results demonstrate that the purity of the extracted DNA in all tested rice samples was sufficiently high for a sensitive PCR analysis and the primer of detected gene appeared clearly at 251pb.Three genes; CaMV 35S promoter, NOS terminator, and insecticide resistant gene Cry1Ac were used to detect of GM rice by PCR, and Real time PCR using oligonucleotide sets targeting to novel genes. The result showed that there was no positive result reaction with conventional PCR, while the outcome of gradient PCR revealed a positive reaction in one sample (Uncle Bens brown) for CaMV35S promoter only. Gradient PCR with 12 replicons for each sample was used for qualitative detection of CaMV35S promoter gene, after optimization of melting temperature and cycles run (45 cycles) , the results appeared positive in the last three grades (63.9, 64.6, 64.9) for CaMV35S promoter, but NOS terminator, and CryIAc were recorded negative results.The result of Real - Time PCR clarified that the CaMV35S promoter specific primer showed strong amplification with Ct, and Tm values were reached into 33.73, 38.63 and 61.55, 62.92 in two samples Uncle Bens brown and Himalayan brown, respectively, whereas NOS terminator gave positive results in four samples Maxims, Laasturiana, Carolin white and Mahatma, and the values Ct and Tm reached to30.87, 30.31, 30.54, 33.75 and 64.53, 64.61, 62.62, 63.87 respectively in comparison with the positive control, while CryI Ac which did not show any positive signal.It was concluded that using molecular methods like Real - time PCR will be useful tool for detecting GM rice such as a part of the approval detection processes because of the rarity of data concerning consumption of GM rice in Iraq.

المستخلص: داء المقوسات الكونديه مرض عالمي الانتشار حيث يصاب معظم الاشخاص ذوي المناعة الجيدة بطفيلي المقوسات الكونديه وغالبا دون ظهور اعراض. ان الهدف الرئيسي لهذه الدراسه هو فهم الفروقات الجنسيه, الهرمونيه والمناعيه في سن البلوغ في الاشخاص الذين لديهم اجسام مضاده نو | Toxoplasmosis is a worldwide disease where most healthy, immunocompetent individuals infected by Toxoplasma are almost asymptomatic.The primary goal of this study is to perceive the hormonal and immunological sex - differences in puberty age who have positive anti - Toxoplasma IgG specific antibodies. The secondary goal is to inspect the endocrine - immune interaction in these persons by detecting the effect of testosterone and oestradiol hormones level on cellular immune response namely, IL - 4, IL - 12. From the first of November 2012 till the end of April 2013, 303 blood samples were collected from apparently healthy male and female students of Al - Erfan, Ignadeen and Algawahery schools and Baghdad University, Both sexes where divided into two age groups : group (A) which included subjects with age range (12 - 15) years old and group (B) which included subjects with age range (16 - 19) years old. All serum samples were tested for toxoplasmosis by using Latex agglutination test and ELISA anti - Toxoplasma IgG antibodies test. As well as, all serum samples were tested by using ELISA technique for detection of serum mean concentration of testosterone, oestradiol hormones, IL - 12 and IL - 4. The results revealed that 107/ 303 (35.31%) of the studied subjects showed seropositive toxoplasmosis, 60 males and 47 females of 107 positive samples showed high significant (p<0.01) differences in comparison to uninfected subjects. Males group B have recorded the highest percentage 34(41.46%) of the infection. Positive association was found between toxoplasmosis and testosterone level in asymptomatic toxoplasmosis cases compared to uninfected group. high mean concentration of testosterone in toxoplasmosis infected males recorded (15.03± 1.04 ng/ml) and (12.4± 0.91 ng/ml) in groups A and B respectively, in comparison to control group which recorded (8.03± 0.78) and (9.86± 0.83) in groups A and B respectively. Also toxoplasmosis infected females revealed high levels of testosterone hormone which represented (4.83± 0.06 ng/ml) and (2.55± 0.03 ng/ml) in groups A and B respectively, with a significant (p?0.05) differences between them, while the control group recorded (0.10± 0.02 ng/ml) and (0.90±0.03 ng/ml) in group A and B respectively.The present study showed a significant (P?0.05) decrease in the mean concentration of oestradiol E2 hormone in toxoplasmosis infected males and females in comparison with uninfected ones. E2 mean concentration was (41± 2.48 ng/ml) and (56± 2.91 ng/ml) for male groups A and B, respectively, in comparison to control group which recorded (67± 2.08 ng/ml) and (74± 2.42 ng/ml) in group A and B respectively, while it was (188 ± 12.48 ng/ml) and (196 ± 16.52 ng/ml) for female group A and B respectively, in comparison to control group which recorded (221±12.09 ng/ml) and (233± 15.63 ng/ml) for group A and B, respectively.The mean concentration of E2 hormone in toxoplasmosis infected females according to their menstrual cycle showed low levels in ovulation, late follicular and luteal phases, which represent (37.5 ± 2.59 ng/ml), (131 ± 16.7 ng/ml) and (76± 3.92 ng/ml) respectively, while the mean concentration of this hormone in uninfected females was (52.4± 2.88 ng/ml), (271.6± 21.04 ng/ml) and (196.2± 12.37 ng/ml) in the three phases of menstrual cycle. This study showed high significant (p?0.05) level of IL - 12 in both males and females with latent toxoplasmosis in comparison with free - toxoplasmosis groups. The mean concentration of IL - 12 in infected males was (4.75 ± 0.88 pg/ml) and (4.12 ± 0.69 pg/ml) in male groups A and B respectively, in comparison to control group which was (2.86± 0.53 pg/ml) and (2.46± 0.62 pg/ml) in groups A and B respectively, while it was (5.60 ± 0.12 pg/ml) and (6.04 ± 0.26 pg/ml) in infected female groups A and B respectively, in comparison to control group which recorded (3.32± 0.89 pg/ml) and (4.27± 0.15 pg/ml) in group A and B respectively. IL - 4 recorded quite elevated level in toxoplasmosis infected males (groups A and B) which was (15.09 ± 0.92 pg/ml) and (17.67 ± 0.78 pg/ml) respectively, in comparison to control group which recorded (13.89± 0.84 pg/ml) and (14.92± 0.69 pg/ml) in groups A and B respectively, Meanwhile the mean concentration of IL - 4 in toxoplasmosis infected females showed mild elevation in both groups A and B which was (15.14 ± 0.84 pg/ml) and (16.06 ± 1.13 pg/ml) respectively, in comparison with toxoplasmosis free subjects which recorded (16.53± 1.22 pg/ml) and (15.15 ± 0.97 pg/ml) with no significant differences between them. Interactions between the endocrine and immune systems may mediate sex differences in response to toxoplasmosis infection.

المستخلص: The study aimed to isolate and identify the Enterococcus spp. from different clinical specimens and study the virulence factors of predominant species, as well as detected the virulence factors encoding genes such as efaA (endocarditis - associated antigen), esp (enterococcal surface protein), eep (stimulating of pheromones expression) and enlA (enterolysin A) genes by PCR techniques.There were three hundred clinical specimens collected from patients suffering from different clinical infections during the period from September 2013 to January 2014 in AL - Sadder Medical City and AL - Hakem General Hospital. The identification of the Enterococcus spp. isolates were depended on colonial morphology, microscopic examination and biochemical tests as a primary identification. The final identification was performed with the automated VITEK - 2 compact system using Gram positive - Identification (GP - ID) cards.According to the results obtained by the VITEK tests forty two clinical isolates of Enterococcus were detected, which distributed into : (22) isolates from urine, (8) vaginal swabs, (6) seminal fluid, (4) throat swabs and two isolates from wound swabs with no isolates from cerebral spinal fluid, stool and blood specimens.This study revealed that the E. faecalis is more distributed with 25(59.52%), followed by E. faecium with 10 (23.80%), E.avium with 5 (11.90 %), E. durans and E. raffinosus with 1(2.39%) for each.The study investigated the virulence factors of E. faecalis, E.faecium and E.avium, which play a major role in enterococcus pathogenicity. E. faecalis and E.faecium had the ability to producecapsule, gelatinase, biofilm, adhesion, protease, bacteriocin, haemolysin and cytolysin except ? - lactamase produced only by E. faecalis while E.avium produced all these virulence factors except gelatinase, bacteriocin and cytolysin.The results revealed variation in the resistance of bacteria to antibiotics, E.faecalis express absolute resistance (100%) to Erythromycin, high resistance against Gentamycin, Tetracyclin and Vancomycin but high susceptibility to Ciproflaxacin and Penicillin and moderate susceptibility to Chloramphenicol. E.faecium exhibited absolute resistance (100%) to Erythromycin, Gentamycin and Tetracyclin, high resistance against Chloramphenicol, Penicillin and Vancomycin but high susceptibility to Ciproflaxacin while E.avium exhibited susceptibility (100%) to all these antibiotics except Tetracyclin showed absolute resistance.Then detected the virulence factors encoding genes : efaA, esp, eep and enlA genes by using PCR techniques and Electrophoresis Systems.Finally, The genotypic method. Regard to genotypic study the outcome showed that 21(84%) isolates of E.faecalis, 4(40%) of E.faecium and 5(100%) of E.avium were carrying efaA gene and 17(68%) of E.faecalis, 5(50%) of E.faecium, 5(100%) of E.avium were carrying esp gene while eep gene was carrying only by E.faecalis and E.faecium ; 12(48%) and 3(30%) respectively. Also the results revealed that only 1(4%) isolates of E.faecalis have enlA gene.

المستخلص: 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

المستخلص: 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.

المستخلص: The study aimed to investigating the role of coagulase - negative staphylococci in human infections, and determining the predominance genes of the virulence factors. Three hundred clinical specimens were collected from out and inpatients undergoing catheter related infections and twenty specimens were collected from healthy hospital staff as a control from January 2013 to July 2013 of Al - Zahraa Teaching Hospital, Al - Sader Teaching Hospital and Al - Hakeem Hospital in Al - Najaf Al - Ashraf province. The specimens were included urine, blood, vaginal swabs, seminal fluid and wound swabs. The specimens were cultured on mannitol salt agar and the primary identification was depended on Gram stained and biochemical tests. Then finally identification with Vitek 2 system is done.One hundred isolates were identified as coagulase - negative staphylococci (CoNS), Staphylococcus haemolyticus was identified as the most frequently isolated species in (53%), followed by Staphylococcus epidermidis (26%) and Staphylococcus hominis were recorded in (21%). Most of CoNS isolates were highly resistance to penicillin G (benzylpenicillin), oxacillin, cefoxitin and erythromycin; and low resistance to rifampicin, levofloxacin and others. While, control isolates results showed moderate resistance to penicillin G and erythromycin; low - level of resistance to cefoxitin, oxacillin and other antibiotics.The investigation of virulence factors revealed that 93% of coagulase - negative staphylococci isolates were production of slime layer, DNase 58%, protease 29% and hemolysin 88%. But the results gave negative result for TNase and lipase enzymes.Monoplex and multiplex PCR were used to explore the MecA, aap, icaA, icaD, atlE, sea, seb, sec, sed, hla, hlb, sspA, sspB, geh, nuc genes. The results showed that all CoNS isolates (100%) had mecA and atlEgenes, but 98% of isolates had aap, 93% icaA and icaD genes. PCR revealed that only (14%) of isolates had genes for enterotoxins expression. (92.86%) and (7.14%), sea and seb respectively, in contrast, the sec and sed genes were not be recorded.The result showed that 47% of CoNS isolates had hla gene and 41% contain hlb gene, 29% were positive for the sspA gene whereas the sspB gene and geh and nuc2 genes not found in any of staphylococcal isolates. Finally, the result indicated that 58% of CoNS isolates were expressed the nuc1 gene.Plasmid curing was carried out in order to determine the origin of resistance and some virulence factor genes (chromosomal or plasmid - borne gene). The curing (elimination) of the plasmids of coagulase - negative staphylococci isolated was catalyzed using ethidium bromide in different concentration and high temperature (44?C). The results showed that the oxacillin resistant coagulase - negative staphylococci were plasmid mediated since 93% of the isolates showed negative result on oxacillin resistance screening agar, and absence of mecA gene from all isolates. Also, 41 of coagulase - negative staphylococci isolates that showed ? - hemolysin became non - hemolysin after manipulated with ethidium bromide.Finelly, taking into consideration the etiological importance of CoNS has often been neglected, the present investigation confirmed that these microorganisms should not be ignored or classified as mere contaminant.

المستخلص: استهدفت الدراسة الحالية عزل وتشخيص بكتيريا Streptococcus mutans المسؤولة عن تنخر الاسنان البشري والتكلسات (plaque) واستخراج اضداد لها من صفار بيض الدجاج Yolk Immunoglobullin (IgY) لغرض استخدامها مستقبلا كمثبطات لنمو هذه البكتيريا الخطيرة ويمكن مزجها مع مع | The presented study aimed to isolate the main agent for dental caries and teeth plaque, Streptococcus mutans bacteria, and then production of specific antibodies against these harmful bacteria by the use of chicken egg yolk immunoglobulin (IgY). S. mutans had been proposed as the main etiological agents of dental caries and high levels of mutans streptococci in the plaque is correlated with a higher risk for dental caries. Seventy five plaque samples were collected from human teeth. Forty two samples were considered to be positive bacterial isolates using MS - agar (Mitist Salivares agar). Thirty five isolates were considered belonging to the group Streptococci; among these isolates 29 isolates were expected to be belonging to mutans streptococci group according to ability of producing special kind of exopolysaccharides. Ten isolates were considered as S. mutans with a percentage of 41% depending on staining with triphenyltetrazolium chloride and tolerance with NaCl 4%, 6 isolates were classified as serotype C by using Lancefield grouping identification. These isolates were tested for production of extracellular Glucosyltransferase (GTF) through determination of their enzyme specific activity. All isolates were able to produce the enzyme; Streptococci isolate (H5) identified as Streptococcus mutans serotype C was selected as the best producible isolate for GTF with a specific activity of 2.6 U/mg. It was found that GTF of the chosen isolate (H5) was produced during the middle stationary phase (18 - 35 hr.) and its maximal productivity was reached at 22 hr. Purification of S. mutans serotype (C) H5 GTF were done by ammonium sulfate, ion - exchange chromatography (DEAE - Sephacel column), and gel - filtration chromatography using Sepharose 6B column. The best percent saturation use for precipitating GTF by ammonium sulfate was 20 - 40% with specific activity 3.4 U/mg. Two purified GTF enzymes (GTF - I and GTF - II) were detected with specific activity 8.3 U/mg, 35.5 U/mg after 22.6, and 96.1 fold of purification respectively with yield 17.2%. Purification S. mutans CA - GTF (H5) were done by 8M urea, ammonium sulfate, DEAE - Sephacel column and gel - filtration (sepharose 6B) column chromatography. The purified CA - GTF was detected with specific activity 18.1 U/mg after 24.5 fold of purification with yield 20.2%. Determination of purified GTF (GTF - I, GTF - II) and CA - GTF molecular weight was done by using gel - filtration chromatography (sepharose 6B) column with presence of standards proteins. It was found that the molecular weight of GTF - I, GTF - II and CA - GTF was 125.819, 112.201 and 84.139 dalton, respectively. The ability of GTF, CA - GTF and whole cell of S. mutans to stimulate the immune system of avian hens was tested. The intramuscular rout injection of three purified antigens (GTF, CA - GTF and whole cell) in the chest of experimental hens was done. IgG from egg yolk hens (IgY) was purified through the post immunization period (9 weeks) by using polyethylene glycol (PEG) precipitation and protein content of IgY antibodies was estimated from egg yolk and serum. Each one milliliter of purified IgY egg yolk samples GTF, CA - GTF and Whole cell, protein contained 7.06, 6.97, 3.9 mg/ml, respectively while in serum protein content about2.6, 3.1 and 3.25 mg/ml, respectively. The Sodium dodecyle sulfate polyacrylamide gel electrophoresis (SDS - PAGE) of anti - GTF (IgY) indicated that purified IgY gave two bands; 47.863 and 34.673dalton which were considered to be IgY heavy and light chains respectively. the IgY - CA - GTF sample is the best in terms IgY specificity 34.07% while the two samples (GTF, Whole cell) performed 30.5% and 29.3% respectively, Igy - GTF the best in terms purity 49% followed IgY - CA - GTF 47% and IgY - whole cell 46.3%. The immunological specificity of the three IgY samples preparations was assessed by ELISA test and the best sample that produced high titration was IgY - GTF with concentration 3.5 mg/ml, followed by the IgY - CA - GTF and IgY - whole cell with concentration 3.28 and 3.1 mg/ml respectively. The IgY - GTF inhibited approximate 75% of the specific activity GTF, while IgY - CA - GTF inhibited 50% of the specific activity CA - GTF. A double immunodiffusion test for detection of the immune response between anti - GTF IgY and purified GTF, CA - GTF and Whole cell antigens were recorded. The immunological response of anti - GTF and anti - CA - GTF was indicated by the appearance of precipitation lines on the surface gel between anti - GTF and two antigens GTF and CA - GTF while in the anti - CA - GTF and anti whole cell only with homologues antigen. The effect of different concentration of inhibitor (Amoxicillin) and anti - GTF, anti - CA - GTF and anti - whole cell on the growth of S. mutans bacteria were tested using broth dilution method and diffusion method on solid medium. Anti - GTF and anti - CA - GTF had no effect on the growth of S. mutans(H5) serotype C, while anti - whole - cell and Amoxicillin were capable to inhibit the growth of bacteria at concentration 20µg/ml and 15µg/ml respectively. The minimal inhibitory concentrations in which these concentrations were noticed at 35µg/ml and 30 µg/ml respectively. The highest zone of inhibition (40 mm) was recognized with Amoxicillin at concentration of 50 µg/ml, followed by anti - whole cell with a zone of inhibition of 34 mm at concentration of 70 µg/ml.

المستخلص: اجريت هذة الدراسة في معهد الهندسة الوراثية والتقنيات الاحيائية في جامعة بغداد خلال الفترة من تشرين الثاني 2012 الى ايار 2013، للكشف عن علاقة تسوس الاسنان بين مرضى السكري والمرضى غير المصابين بالسكري DDCP) و(NDCP اعتمادا على تسوس الاسنان من انواع Streptoco | The present study was carried out in Genetic Engineering and biotechnology Institute / University of Baghdad during the period from November, 2012 to May, 2013 to detect the relationship between diabetic and non - diabetic patients according to the dental caries occurrence and its causes by Streptococcus spp. (S. mutans, S. salivarius and S. oralis (which are isolated from oral cavity, In addition, this study was carried out to study the comparison between the traditional (bacterial culturing) and molecular diagnosis methods. The total number of the studied groups was 95 Iraqi patients (45 diabetic dental caries patients (DDCP) and 50 non - diabetic dental caries patients (NDCP) of both genders who their ages ranged from 18 - 65 years old. The patients, samples including saliva and buccal swabs that randomly collected from DDCP and NDCP who were reviewing Al - Alweyia Centers of Dental Caries and Diabetic Diseases in Al - Yarmook hospital in Baghdad city. The distribution of patients who have dental caries according to genders showed high significant differences at (p<0.01) between two genders (30 females, 15 males) for diabetic dental caries patients, while in non diabetic dental caries patients, there were significant differences at (p<0.05) between two genders (29 females, 21 males). The distribution of diabetic dental caries patients according to age showed high significant differences at (p<0.01) between two genders in age group of 36 - 50 years old, While low significant differences at (p<0.05) between two genders in age group of 20 - 35 years old and no significant differences between two genders in age group more than 50 years old, In another hand in non diabetic dental caries patients, there were no significant differences between two genders in all age groups. The results of samples (saliva and buccal swabs) culturing on mitis salivarius bacitracin agar media (MSBA) appeared that out of 95 bacterial cultures, 67 bacterial cultures were grown (32 bacterial cultures for diabetic dental caries patients and 35 bacterial cultures for non diabetic dental caries patients); S. mutans, S. salivarius, and S. oralis species were identified according to the results of microscopic examination, API kit 20 - strep, hemolysis on blood agar, motility test and catalase test. The molecular study focused on the analysis of DNA which extracted directly from saliva, buccal swabs and from the bacterial culture cells of S. mutans, S. salivares and S. oralis from both diabetic dental caries patients and non diabetic dental caries patients. Polymerase chain reaction (PCR) results revealed the presence of the product with 433, 544, and 374 bp which were related to gtfD (S. mutans), gtfK (S. salivarius) and gtfR (S. oralis) respectively in all samples (saliva, buccal swabs and bacterial culture). According to the presence of these three genes, there were high significant differences at (p<0.01) between diabetic dental caries patients and non diabetic dental caries patients, while there were no significant differences according to the percentage of presence of each gene between the three species of bacteria. Sequencing of the PCR products of the gtfs (gtfD, gtfK, and gtfR) genes region showed that nine samples gave acceptable results according to National center for Biotechnology Information (NCBI) matching, while 3 samples gave no results; this may be due to an error in sequencing system. The sequencing analysis of gtfs gene (gtfD, gtfK and gtfR) revealed that in DDCP the highest percentage of recorded mutations was in the gtfR gene.While in non diabetic dental caries patients, the highest percentage of recorded mutations in the gtfK gene than gtfR genes. In gtfR gene all mutations were substitution for diabetic dental caries patients and non diabetic dental caries patients. Nevertheless, in diabetic dental caries patients the mutations in gtfK and gtfD genes distributed between substitution and deletion mutations without recording any type of insertion mutation. But, in non diabetic dental caries patients, in gtfD all mutations were distributed between three types of mutations (substitution, insertion and deletion). The highest percentage of the effect of mutations in gtfs genes (gtfD, gtfR and gtfK) in diabetic dental caries patients were silent and missense mutation's than the frameshift mutations. on the other hand, the highest percentage of the effect of mutations in gtfs genes (gtfD, gtfR and gtfK) in non diabetic dental caries patients was missense mutations as compared with the other two types of silent and frameshift mutations

Genomic DNA was isolated by using Geneaid DNA extraction kit from the whole blood; conventional PCR (SNP - 44 and Del/Ins - 19) and PCR - RFLP (SNP - 43 and SNP - 63) were used to detect the calpain10 variants by using specific primers and restriction enzymes. The study population consisted of 50 subjects with type 2 diabetes and 50 with normal fasting blood glucose (80 - 110 mg/dl). The type 2 diabetic subjects were recruited from the National Center for Diabetes treatment and Research. The non - diabetic control subjects were recruited from the same area as the comprising blood donors, healthy volunteers, or hospital /university staff members. Previous studies have detected a role for Calpain - 10 (CAPN10) polymorphisms in susceptibility to Type 2 diabetes mellitus (T2DM) in many populations. This study aimed to evaluate possible associations between these polymorphisms in the CAPN10 gene (SNP - 44, SNP - 43, Del/Ins - 19, and SNP - 63) and T2DM incidence in Iraqi population. Enrichment of allele 1(2R) in Del/Ins - 19 and 2R/2R genotype were found in T2DM patients. While the alleles and genotypes distribution of SNP - 44, SNP - 43 and SNP - 63 were not significantly different between patient groups and non - diabetic control subjects. The genotype AA in SNP - 43 and genotype TT in SNP - 63 were not found neither in T2DM nor in control subjects. of the eight haplotypes detected, enrichment of both haplotype 112 defined by variants of SNP - 43, Del/Ins - 19, and SNP - 63 and haplotype 2112 defined by variants of SNP - 44, SNP - 43, Del/Ins - 19, and SNP - 63 were seen in patients. The distribution of the other haplotypes was comparable between patients and control subjects. The calpain10 haplotype combinations were also obtained, and the haplotype combinations 111/111 and 111/112; which are created by variants of SNP - 43, del/ins - 19 and SNP - 63 and; haplotype combinations 1111/2111, 1111/2112 and 1121 / 2222; created by SNP - 44, SNP - 43, del/ins - 19 and SNP - 63; were associated with increasing the risk of T2DM.

المستخلص: In this study, natural lignan dimer was isolated from nutmeg seeds (Myristica fragrans) using organic solvent, partially purified using liquid/liquid partiation, purified using anion exchanger and chemically characterized using Benedict’s Reagent, Fehling’s Reagent and Molish’s Reagent. Then, by the aid of UPLC - PDA - IT - TOF - MS System, the molecular weight (626.221 Dalton) and the molecular formula (C39H45O7) of this dimer were determined. After that, the free radical scavenging activities were studied using stable free radical compound 1, 1 - Diphenyl - 2 - Picryl - hydrazil (DPPH). Results showed that 100, 10, 1 and 0.1 ?g/ml of purified lignan had 76.7 %, 65%, 28% and 8% scavenging activity respectively, while the same concentrations of partial purified lignan had 44.3%, 18.5%, 11% and 0% scavenging activity respectively.MTT(3 - (dimethylthiazol - 2 - yl) - 2, 5 - diphenyl tetrazolium bromide) assay was conducted to determined the IC50 for both purified and partial purified lignan using 4 different cell lines A549 (human lung adenocarcinoma epithelial cells), MCF7 (breast cancer cells), PC3(human prostate cancer cells), and HepG2(liver hepatocellular cancer cells), and to determine which cells type were be affected more by this natural lignan dimmer.The IC50 values for purified lignan were 85.17, 51.16, 108.4 and 60.21 ?g/ml while the IC50 values for partial purified one were 170.1, 84.14, 154.4 and 151.3 ?g/ml using A549, MCF - 7, PC - 3 and HePG2, respectively.The high content screening analysis (HCSA) and Cellomics Thermo Scientific maltiparametric Kits were used for the evaluation of cell - lignan interaction; 100, 50 and 25 ?g/ml of purified lignan caused 87.22, 69 and 53.36% reduction in MCF - 7cell count respectively and the same concentrations caused 98.1, 97.5 and 98.55% nuclear morphology changes. Results also revealed that these concentrations caused 7.7, 7.0 and 5.83% increase in MCF - 7 cells permeability respectively and they also caused 12.22, 11.15 and 0.2%decrease in mitochondrial membrane potential respectively, while these concentrations caused 11.12, 10.1 and 10% increase in Cytochrome C releasing from mitochondria to cytoplasim respectively.Reactive oxygen species (ROS) induction in MCF - 7 cells in the presence of 200, 100 and 50 ?g/ml of purified lignan caused 20, 11.48 and 9.61% ROS reduction respectively.MCF - 7 cell cycle was studied in the presence of 100, 50 and 25 ?g/ml of purified lignan, and results revealed that this compound blocked cell cycle at Sphase and the percentages of S - phase cells reduction were 74.33, 52.4 and 67%, respectively. This reduction was dose dependent while the same concentrations had no effect on MCF - 7 mitotic cells. Cell cycle arrest was detected immunofluorescently using BrdU antibodies (S - phase cell staining) and phosphor - Histone H3 antibodies (M - phase cells staining

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

المستخلص: Markers have been described in type 1 diabetes mellitus (T1DM), There is a number of specific and non specific antigens have been identified. The major autoantigens involved in the destructive process of beta - cells leading to the development of type 1 diabetes are insulin hormone, glutamic acid decarboxylase (GAD), tyrosine phosphatase enzyme or Insulinoma - associated Antigen - 2(IA - 2).This study was conducted to find the relationship between antibodies for this antigens (insulin, GAD and IA - 2) and T1DM which could be used for the early detection of T1DM in normal Iraqi population. To study the importance of anti - thyroid peroxidase (anti - TPO) as a marker for autoimmune thyroid disease (ATD) in T1DM patients, and to find the relationship between T1DM and ATD.The study was carried out on 50 blood samples of men and 30 blood samples of women with age ranged from (20 - 60 years old), they were divided in to three groups : 1. Group 1 (20 men and 10 women) whom have fasting plasma glucose (FPG) above 180 mg/dL.2. Group 2 (20 men and 10 women) whom have FPG ranged from 120 - 180 mg/dL.3. Group 3 (10 men and 10 women) whom have FPG below 120 mg/dL.Blood samples were collected from all subjects, FPG and glycated haemoglobin (HbA1c) were measured. The levels of insulin, anti - insulin, anti - GAD, anti - IA - 2 and anti - TPO antibodies were measured in the serum.The statistical analysis results showed no significant difference in the presence of antibodies, HbA1c and FPG between men and women groups, inspite of some simple differences between the two groups.A significant (p<0.05) elevation in the level of FPG and HbA1c was observed in diabetic patients group compared withnon diabetic group. Significant (p<0.05) decrease in the level of insulin of T1DM patients was noticed compared to non diabetic group. Significant (p<0.05) elevation in the level of (anti - insulin, anti - TPO) in T1DM patients compared with non diabetic group. Elevation in the level of (anti - GAD, anti - IA - 2) in the T1DM patients compared with non diabetic group.The results also showed that no positive results for (anti - insulin, anti - TPO) present in the non diabetic group. One positive result for anti - GAD and one positive result for anti - IA - 2 present in the non diabetic group, which indicate the importance of anti - GAD and anti - IA - 2 antibodies ssay in normal population that could be used as early detection of T1DM.

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

Lippia nodiflora (L.) Rich.29. Tribulus terrestris L.Some of these species have been anatomically investigated for the first time.Anatomical characters might be useful for plant biologist for the identification of important wild plants as an additional character at global level. Comparative anatomical characters were used; such as characteristics of ordinary epidermal cells of stems and leaves and stomatal complexes. The epidermis possesses number of important diagnostic character that offer valuable clues for identification, like size, shape, in addition to indumentum of both stems and leaves. Venation system was investigated and compared. Cross sections of root were useful taxonomically especially the thickness of epidermis, cortex, phloem and xylem. The study observed presence of sclerenchyma tissues in the root cortex of some species. Cross sectioning of stems and petioles were also studied. Epidermis, cortex, pericycle, vascular bundle shapes and numbers, pith characters, presence of crystals and tannin filled cells were useful aid in distinguishing species. Vertical sections of leaf blades, shape and number of vascular bundles, thickness of palisade and spongy layers and other mesophyll characters were important taxonomically.ccording to some of these characters, species were divided into groups. This study concluded the presence of variations in characters and these were presented for the first time comparatively, so that, the anatomical characters were a good support to the exomorphological characters in the studied species. Field photographs of the different studied plants and sections of organs were put in addition to numerous tables in this work. The above results were discussed scientifically regarding mainly the environmental factors.

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

Three Macro - algae were isolated, Cladophora glomerata (N) and Enteromorpha ralfsii from Baher Al - Najaf region in Holy Najaf city. In addition, C. glomerata (R) was isolated from Al - Rashdiya, north of Baghdad.Phytopathogenic fungi from soil and some infected fruits were also isolated. They were identified as Pythium ultimum and Rhizoctonia solani.Water and ethanol were used to extract each algae to evaluate their antifungal activity against isolated phytopathogenic fungi. Different concentrations of these algal extracts had been prepared which are (10, 25 and 50) mg/ml and the antagonistic activity against the isolated phytopathogenic fungi were evaluated, the hot and cold water extracts did not show any antagonistic activity against fungi. However, all these extracts were ignored in the future work for this study. Furthermore, the hot ethanolic extract was more efficient than these of cold ethanolic extracts. Results have been shown that there were significant differences when macro - algal ethanolic extract were used.C. glomerata (R), which isolated from Al - Rashdiya, was more efficient against tested fungi than the same alga what isolated from Baher Al - Najaf region. However, E. ralfsii extract was more efficient against tested fungi than C. glomerata (N). Percentage of inhibition against P. ultimum when hot ethanolic extract of E. ralfsii, C. glomerata(R) and C. glomerata(N) were (88.8, 83.3 and 63.3) respectively.However, results for cold ethanolic extract of the same algae were (63.3, 52.2 and 32.2) respectively when 50 mg/ml of algal extracts were used.Percentage of inhibition against R. solani when hot ethanolic extract of E. ralfsii, C.glomerata (R) and C.glomerata(N) were (94.4, 100 and 78.8) respectively.However, results for cold ethanolic extract of the same algae were (66.6, 64.4 and 48.8) respectively when 50 mg/ml was used. According to the difference in biological activities against those phytopathogenic fungi caused by the same species of macro - algae or different genera from different environments. Due to difference in biological activity of the same macro - algae species Physiochemical parameter for each environments obtained such as air and water temperature, Turbidity (NTU), Electrical Conductivity(EC)and Salinity%, Water pH, CA+2 concentration, Mg+2 concentration, Total Hardness and Total Alkalinity. Results indicated that soaked Cucumis sativus and Capsicum annum seeds in cold and hot ethanolic macro - algae extracts of (E. ralfsii, C. glomerata (R) and C.glomerata (N) for 24 hours were able to protect seed germination that have been grown in a Petri dish contaminated with P. ultimum and R. solani comparing with control. In addition, results indicated that spraying C. sativus and C. annum seedling with these algal extracts within two weeks old again protects these seedlings from the same phytopathogenic fungi either before or after 24 hr. However, results indicated that adding the algal extracts within two months age to the C. sativus and C. annum plants again protects these plants from the same phytopathogenic fungi comparing with control and fungicide treatment. Moreover, results indicated that the active chemical compounds in E. ralfsii was Tannins, Saponins and Flavonoids. While C. glomerata was contained Tannins, Saponins, Alkaloid and Phenols. Results indicated that both hot crud methanolic extract of C. glomerata (R) and E. ralfsii have a lot of active chemical compounds against micro - organisms by using the GC - Mass Spectrometry technology.

المستخلص: تضمنت الدراسة الحالية معرفة بعض التاثيرات الفسلجية والكيموحيوية للمستخلصات المائية للكرفس (Apium graveolensL) والجرجير(Eruca sativa Mill) والطماطم (Lycopersicon esculentum Mill) في الدم والجهاز التناسلي لذكور الجرذان البيض المعرضة للاجهاد التاكسدي المستحد | The aim of the present study was to investigate some physiological and biochemical effects of the aqueous extract of celery (Apium graveolens L.), gardeen rocket (Eruca sativa Mill) and tomato frait (Lycopersicon esculentum Mill) on blood and male reproductive so system of Albino rats (Rattus norvegicus) exposed to oxidative stress induced by hydrogen peroxide 0.5% with drinking water for 21 days using vitamin E, as well known antioxidant as criterion for comparison. For the purpose of this study, preliminary experiments were carried out to find the most effective doses of plant extracts and it was found that these doses were 100, 150, 250 mg/kg body weight for, tomato, celery and gordeen roket extracts respectively. Fifty rats (12 - 14 weeks age) were randomly divided to ten groups (treatments) each with five replicates.These groups are : Group (1) (control group) : Rats without any treatment.Group (2) : Rats treated with H2O2.Group (3) : Rats treated with celery extract (150 mg/kg b.w.).Group (4) : Rats treated with celery extract (150 mg/kg b.w.) and H2O2.Group (5) : Rats treated with Eruca extract (250 mg/kg b.w.).Group (6) : Rats treated with Eruca extract (250 mg/kg b.w.) and H2O2.Group (7) : Rats treated with tomato extract (100 mg/kg b.w.)Group (8) : Rats treated with tomato extract (100 mg/kg b.w.) and H2O2.Group (9) : Rats treated with vitamin E (500 mg/kg b.w.).Group (10) : Rats treated with vitamin E (500 mg/kg b.w.) and H2O2 Results could be summarized as follow : 1. Compared with the control, the oxidative stress induced by H2O2 caused significant increase in total count of leukocytes, neutrophilis, acidophils, basophilis, monocytes and lymphocytes, and in the level of blood sugar (glucose), Total cholesterol, triglycerides(TG), low density lipoprotein (LDL - C), very low density lipoprotein (VLDL - C) atherogenic index (First and second), Urea, Malondialdehyde (MDA) and percentages of dead sperms and abnormal sperms.This stress showed as well, a significant decrease in body weight, Hb, PCV, high density lipoprotein (HDL - C), total protein, Albumin, glutathione, sperm total number, percentages of motile and normal sperms, testes weight, prostate and epididymis weights and seminiferous tubules diameter. This treatments, however, showed no significant variations in activity levels of ALT and AST enzymes and seminal vesicle weight.2. In comparison with treatment (2) (rats treated only with H2O2) , the treatment of rats, under oxidative stress with celery extract showed a significant decrease in total count of leukocytes neutrophils, lymphocytes and in blood suger, cholesterol TG atherogenic (First index) blood urea, MDA, Percentage of dead and abnormal sperms and seminal vesicle weight.This treatment showed also a significant increase in level of Hb, PCV., body weight, total protein, Albumin glutathione, number of sperm, percentages of motile and normal sperms, testis weight, epididymis weight and prostate weight. However no significant variations were detected in levels of acidophils, basophils, monocytes, HDL - C, atherogenic (second index) and seminituferous tubules diameter.3. Treatment of Eruca extract and compared with the treatment of H2O2, showed significant decrease in lymphocytes number and in the level of blood sugar, cholesterol (T.G), LDL - C, VLDL - C and atherogenic (first and second index) blood urea, MDA, percentage of dead and abnormal sperms and seminal vesicles weight. The treatment showed also a significant increase in body weight, numbers of acidophils, monocytes, basophils, HDL total sperm numbers, percentages of motil and normal sperms and weights of testis, epididymis and prostate.However, no significant variations were observed in Hb, PCV, Leukocyte total counts, neutrophil, albumin, ATL and AST and seminiferous tubule diameter.4. The treatment of tomato extract showed similar results to that of celary and Eruca extracts except, a significant increase in AST enzyme and seminiferous tubules diameter was detected in case of tomato extract (i.e not seen in case of other plant extracts).5. Compare with H2O2 treatment, rats under oxidative stress treated with vitamin E (500 mg/kg b.w) showed significant decrease in lymphocyte numbers, Total cholesterol, TG, LDL - C, VLDL - C, atherogenic (first and second index), urea, MDA and percentages of dead and abnormal sperms.At the same time the vitamin E treatment showed a significant increase in body weight , Hb, neutrophils, acidophils , monocytes, total protein, glutathione, total sperms number, percentage of motile and normal sperms, and weights of testis, epididymis, and prostate.However, this treatment (compared with H2O2 treatment) showed no significant difference in the level of PCV total count of leukocytes, basophils, blood sugar, HDL - C, albumin, ALT, AST, seminal vesicle weight and seminiferous tubules diameter 6. The most important histological changes exhibited by the animals under oxidative stress were apparent interstitial degeneration, necrosis of supporting and spermagonial cells, separation of these cells in semicyclic manner from the basement membrane, decrease in spermatids (spermatoblasts) and mature sperms in seminiferrous tubule cavity.These effects (due to H2O2 treatment) were decreased to minimal levels when the H2O2 treated rats exposed to plant extracts and vitamin E, used in this study.7. Animals treated with plant extract or vitamin E alone (i.e not treated before with H2O2) showed no clear difference from the control animal (without any treatment) though some improvement was observed in some physiological, biochemical and histological characters of blood and male reproductive system of the studied animals The above results revealed that the plant extract used in this study play an important role in decreasing the harmful effect of the free radicals in the animals (rats) studied.

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

المستخلص: جمعت 265 عينة من مستشفى تكريت التعليمي العام وشملت هذه العينات عينات سريرية لمرضى راقدين في المستشفى ومرضى مراجعين لها. اخذت العينات من المرضى المشتبه باصابتهم بخمج السبيل البولي وخمج الجروح والحروق وخمج الاذن الوسطى ولكلا الجنسين وباعمار مختلفة. انجزت هذ | A number of 265 samples had been collected from Tikrit Teaching Hospital (T.T.H.).These samples were taken from inpatients and outpatients suspected to have Urinary Tract Infection, Wound & Burn Infections and Mid - Ear infection for males and females in varied ages. The practical part had been fulfilled during the period from the beginning of December 2006 till the beginning of March 2007.Isolates diagnosed were identified depending on morphological and cultural characteristics. The results revealed 60 Staphylococci isolates, which shows 27 isolates (45%) were S. epidermidis, 13 isolates (21.66%) S. saprophyticus, 10 isolates (16.67%) S. xylosus, 3 isolates (5%) S. lentus, two isolates (3.33%) S. heamolyticus, and one isolate (1.67%) for each of S. simulans and S. hominis Ten (34.48%) of patients are located in the age group (15 - 30) years. while concerning the classification according to sex, females were (65.5%). Otitis media and Wounds and Burns infections, their ratio was high (61.1%, 53.8%) consequently both in males in comparison with females. Concerning the relationship between the infection and the residence and the level of education, the results revealed that isolation of Coagulase Negative Staphylococci (CoNS) were high in rural areas and in uneducated persons regarding the various infections than those live in urbans and educated ones. A of main tests were carried out in order to achieve the purpose of this study according to the planned goals, some of which are the virulence factors of Coagulase negative Staphylococci. These include DNase, Urease, Lipase, Lecithinase, and Alkaline phosphatase.The results revealed the ability of 67.5% of isolates to produce Alkaline phosphatase, and 46.6% of isolates to produce Urease, also 27.5% of isolates were able to produce Lecithinase , and the ability of 19.16% to produce Lipase, while 22.5% of isolates were capable of producing DNase. In addition to these tests, the test for producing ? - lactamase was done, 85% of isolates were positive to this test because ? - lactamase is one of the significant enzyme which are produced by bacteria since it improves the resistance of bacteria for antibiotics. Thirteen different antibiotics used for the Antibiotics susceptibility tests which show that most effective antibiotic is Nitrofurantoin (95%), followed by Amikacin (93.3%), Novobiocin(90%), Chloramphenicol(88.3%), Rifampicin (78.5%), Vancomycin (75%), Ciprofloxacin (73.3%), Clindamycin (70%), Gentamicin (58%), Penicillin G (50%), Trimethoprim (50%), Tetracycline (40%) and Cefoxitin (18.3%).
