المستخلص: The violent criminal behavior is emerged from the interaction between several genetics and environmental factors. The present study reflect the role of polymorphisms in dopaminergic system genes (drd2 ,comt ,dat1 ,drd4, and maoa) on violent criminal behavior in Iraqi prisoners.This research was a case - control study , blood samples were collected from 200 prisoners (case group) who convicted with terrorism (150 sample), murder (30 sample) and drug trading (20 sample) Issues selected from Al - Hilla reformist central prison for men and women in Babylon city and from position and deporting division in Karbala .This sample included (160 male and 40 female). Additionally, 100 sample were collected as control group included (54 male and 46 female).DNA was extracted and the polymorphisms analysis achieved by Restriction Fragment Length Polymorphism (RFLP - PCR) for drd2 and comt genes ,while the dat1 ,drd4 and maoa polymorphisms was analyzed by Polymerase Chain Reaction (PCR).All polymorphisms (except drd4) were subjected to PCR - sequencing for confirming the presence of polymorphisms .The results showed that the percentage of the case group was 34.5 % with an age ranged between 20 - 39 years ,most of them were male 80% ,72.5% were married ,77.5% were from rural area ,84% were self - employed and 41.5% were illiterate .Genetic analysis of drd2 TaqIA polymorphism demonstrated that a significant increase in the genotype frequency of A1/A1 was observed in case group (p = 0.03; OR= 4.93 ; 95% CI=1.08 - 22.5) and the A1 allele frequency was significantly associated with criminal behavior (p=0.03 ;OR=1.51; 95% CI=1.04 - 2.21).The comt (Val 158 Met) polymorphism revealed that the homo - mutant genotype A/A had significant higher risk of criminal behavior (p= 0.001 ;OR= 3.98 ; 95% CI= 1.7 - 9.3) when compared with control group. and the A allele(met allele) frequency was significantly associated with case group (p=0.003; OR= 1.68; 95%CI= 1.19 - 2.37).On the other hand , the analysis of VNTR polymorphism in dat1 gene showed non - significant difference in 9/9 genotype and 9R allele frequency between the study groups (p>0.05).The VNTR polymorphism analysis for drd4 gene revealed that the criminal individual who carried 7/4 genotype was significant higher than in control group (p=0.03;OR= 2.6, 95%CI= 1.09 - 6.17), and the 7R allele frequency was significantly associated with case group (p=0.04;OR=2.06; 95%CI= 1.04 - 4.1).Finally, the maoa VNTR polymorphism was analyzed in male and female separately due to the gene location on X - chromosome .The results demonstrated that there was non - significant difference observed between all genotypes and alleles frequencies between case and control male (p> 0.05),whereas in female a significant association in 3.5/3.5 and 5.5/4.5 genotypes (p<0.01) ,additionally the 3.5 R alleles was associated with higher risk of violent criminal behavior in female (p= 0.004;OR=2.62; 95%CI=1.36 - 5.05).These results suggested that the drd2 ,comt ,drd4 and maoa in female polymorphism might increase the susceptibility of individual to engage in to crimes in the presence of certain environment risk factors.

Many of studies have shown the critical part of TLRs in different parasitic diseases. The present study were performed to detect TLRs 7 and TLRs 9 genes and related cytokines in 125 aborted women as case group and 30 healthy women (15 non pregnant and 15 pregnant women) as control groups in the Maternity and children Hospital in the Al - Qadisiyah province from December 2015 till March 2016, Five milliliter of venous blood sample were obtained from each woman under sterile condition. Three aspects were involved in this study; the first aspect included the measurement of sera antibodies (IgG& IgM) in the aborted women and control and study epidemiological aspects for T. gondii infection. The second aspect determined the levels of cytokines (IL - 12 Pg./ml , IFN - γ Pg./ml) and human proflin - 1 (PFN - 1 Pg./ml) in the sera of aborted women and control. The levels of cytokines (IL - 12 , IFN - γ) and PFN - 1 in blood were detected by using ELISA principle. The third aspect focused on detection of TLR7 gene and TLR9 gene in extraction DNA of aborted women and control (non pregnant and pregnant women) by Polymerase Chain Reaction (PCR). The outcomes demonstrated the seroprevalence of IgG (latent infection) and IgM (recently acquired infection) anti - Toxoplasma antibodies were positive in 55/125 cases (44%) and 5/125 cases (4%) respectively, however the Overall Seroprevalence of anti - T.gondii antibodies in aborted women was 48%. Mixed seropositive for IgG and IgM were not recorded in the present study, whereas the control were 0% for all antibodies. Significant relationship (P< 0.05) was found between the seroprevalence of T.gondii as ( chronic infection , age groups of the aborted women, several chronic diseases and abortion time). The results showed no statistically significant association between Toxoplasma infection and the ability of women to have children and frequency of abortions. The results confirmed that the aborted women with positive IgG antibody have significant increase in IL - 12 concentration in comparison with control , while no significant increase in IgM in comparison with control groups at LSD value ( 30.28). The concentrations of IFN - γ were lower in positive IgM aborted women than IgG , both groups of aborted women have significant decreased in comparison with pregnant control. While IgM patients have significant decreased in comparison with pregnant and healthy control group at LSD value (19.33). The human profilin - 1 levels were lowered in infected aborted women with IgG and IgM antibodies in comparison with pregnant and healthy control at LSD value ( 230.14). The genetic profils of genes TLRs have explained that TLR7 and TLR9 were (89.1 %) , (84.7 %), Respectively in aborted women. The results illustrated the presence of some genetic variation (TLR7 and TLR9 gene) in aborted women compared with the control, and this means having mutations in the patients gene.

المستخلص: This study is adescriptive exploratory study in Thi - Qar providence for some breast cancer patients . This study aims to assess the relationship between gene expression for each type four of the collagen (IVCollagen) and gene expression positive for both estrogen receptor ER - Eestrogen - receptor and progesterone PR - Progestron receptor and fairs tumor HER2 (Human epidermal growth factor receptor) By using chemistry of dyes immunological technique and the nuclear regulatory regions Argyrophilic nucleolar organiser region (AgNOR(. The present study addresses the identification of the type IV collagen content in the basement membrane of epithelial tissue of the breast cancer patients in Thi qar and its relationship to nuclear organization region and maintain its relationship with hormonal receptors and progesterone genetic factor and the extent of their association with the occurrence of breast cancer.Fifty tissue samples are collected from Hussein Teaching Hospital inThi Qar and some private laboratories in the providence each case where data included that the most important factor is age, where he found that the highest percentage of injuries, age (55 - 46 years) increased by 38%. And mixed samples, either partial removal of the tumor or the eradication of whole breast. After collecting samples saved each formalin concentration of 10% for 24 hours at a minimum and then buried with parafin wax and completed the work by histological methods own work.The use of special select number of collagen type IV and determine the type of hormonal receptor positive or negative and also used several positive pathological tissues of the tumor to determine the human epidermal growth factor receptor by using silver nitrate to study the nuclear organization regions. Results of the current study showed that there is a positive relationship between collagen gene expression of type IV and between fairs oncogene(HER2 human epidermal growth factor receptor), as observed the presence of collagen type IV in tissue sections of tumors with HER2 negative gene expression of genetic factor, and with the positive expression for each Estrogen receptor positive ( estrogen positive ) and progesterone receptor positive( Progstrogen positive).Results of this study also showesthe presence of collagen or lack in histological sections of the tumors with positive gene expression of the HER2 oncogene fairs as well as the non - existence of collagen in the sections taken from tumors with negative expression of estrogen and progesterone receptors. The results of the current study also showed that there is a clear positive relationship between nuclear organization regions and between Argyrophilic nucleolar organiser region (AgNOR) Fairs oncogene HER2, as it was noted the presence of many of the nuclear regions of the dye - derived tissue sections of tumors with positive gene expression of the HER2 oncogene fairs, while nuclear chromosomal regions did not appear in the sections derived from tumors with negative expression of estrogen receptor and progesterone hormone. The results of the current study also showed that there is a lack of positive gene expression of collagen type IV, the presence of a number of chromosome regions nucleuse (Argyrophilic nucleolar organiser region (AgNOR)).

المستخلص: This study aimed to verify the distribution of Periplaneta americana and Culex pipiens allergy and its association with some HLA class II alleles in asthmatic and allergic patients. 96 healthy (control ) and 96 suspected allergic individuals from the same geographical region ,paired by sex and age were included in this study. Enzyme Linked Immunosorbent Assay test (ELISA) was used to estimate the total and specific IgE antibodies in the sera of studied individuals. The detection of the HLA - DQB1*0602, HLADQB1* 0604 and HLA - DRB1*12 was performed by Polymerase Chain Reaction (PCR).The results of total IgE based ELISA which was conducted on 96 suspected allergic and24 healthy (control ) individuals revealed that there was extremely significant statistical association (P<0.0001) for total IgE concentration with being allergic or non allergic status of individuals. The overall frequency of higher total IgE antibody concentration ( IgE>200IU/ml) was observed in 72.9% of allergic patients and lower serum total IgE levels (IgE<200IU/ml) were associated with 87.5% of healthy individuals. According to the specific IgE based ELISA results the effect of allergic patients age on the IgE seropositivity against cockroach allergens was not considered to be significant(p>0.05),but the effect of sex was statistically significant)P<0.05(.There was no significant effect( p>0.05)for patients age and sex on the distribution of IgE antibodies against mosquito allergens. Out of 96 allergic patients, 59 (61.5%)and 62(64.6%)showed positive IgE antibody response against cockroach and mosquito allergens respectively. Concerning the PCR results the overall frequency of HLA - DQB1*0602 and HLA - DQB1*0604 alleles was %35.6 and %15.3 of cockroach allergic patients respectively and the HLA - DRB1*12 allele was not observed in these patients..Out of 62 mosquito allergic patients, 8(%12.9)showed HLA - DQB1 * 0602 positive results while HLA - DQB1*0604 allele was observed in 4(%6.5)patients and the HLA - DRB1*12 allele was not observed in these patients.The difference in the genotypig results was extremely highly significant(χ2 : 0.030;17.486; degrees of freedom(DF) : 3;p - value=0.00056136) between cockroach and mosquito allergic patients .The association between the presence HLA - DQB1 *0602 , HLA - DQB1 * 0604 and HLA - DRB1*12 and total IgE based ELISA results in allergic patients and healthy individuals revealed that the percentage of HLA - DQB1 * 0602, HLA - DQB1 * 0604 and HLA - DRB1*12 alleles presence in patients having total IgE lower total IgE )IgE<200 IU/ml) was higher than that of high )IgE>200 IU/ml) total IgE patients where HLA - DQB1*0602 appeared in high percentage(69.2%) followed by percentage (15.4 %( of HLA - DQB1* 0604 presence. . The relationship of HLA - DQB1and HLADRB1 alleles with the results of total IgE based ELISA was statistically significant in the least(χ2 : 60.756 and the degree of freedom (DF) : 5;p= P<0.00001) and greatest(χ2 : 11.806 ; the degree of freedom (DF) : 5 ; p = 0.037544) than 200 IU / ml, values .Depending on the association between the presence of HLADQB1* 0602 ,HLA - DQB1*0604 and HLA - DRB1*12 and positive or negative specific results of cockroach or mosquito allergens specific IgE based ELISA results in allergic patients revealed that the percentage of HLA - DQB*0602,HLA - DQB1*0604 and HLA - DRB1*12 alleles presence in cockroach allergic patients having positive results were higher than those ratios that have been observed in patients with negative ELISA results where HLA - DQB1*0602 appeared in high percentage)35.6%( followed by percentage( 15.3% )of HLA - DQB1*0604 . The relationship of HLADQB1and HLA - DRB1 alleles with the results of specific IgE based ELISA was statistically significant (χ2 : 10.412; DF : 3; p - value =0.01536989).Incontrast the percentage of HLA - DQB1*0602,HLADQB1*0604 and HLA - DRB1*12 alleles presence in mosquito allergic patients was found to be higher in negative ELISA results patients also the relationship of these HLA - DQB1 alleles with mosquito allergen specific IgE based ELISA results was not considared statistically significant (χ2 : 3.115 ;DF : 3 and p= 0.37423205).However HLA - DQB1 * 0602 allele was found in the highest percentage (20.6%), followed by allele HLA - DQB1 * 0604 (8.8%).Concerning the presence of HLA - DQB1*0602 ,HLA - DQB1*0604 andHLA - DRB1*12 in cockroach or mosquito allergic patients and healthy individuals,the HLA - DRB1*12 and HLA - DQB1*0602 allels were not found in healthy individuals.The genotyping results difference between cockroach allergic patients and healthy individuals was considered statistically extremely significant (χ2 : 74.485 ;DF : 5 and p =0) as well as the difference in the results of the genotyping of mosquitoes allergic patients and healthy people was statistically with very high significant (χ2 : 23.342 ; DF : 5 and p = 0.00029035).

المستخلص: The present study was concerned with some biological aspects of the invasive snail Pomacea canaliculata (Lamarck, 1822) and for this purpose, monthly samples from Shatt Al - Arab banks in the area of Al - Salhia were collected during the period from October 2014 to September 2015. The study included the monthly variations in the density of snail , its egg masses and the population sizes. In the laboratory, the study included many aspects, these are the relationships between female weight with some measurements of its egg masses, embryonic development duration, hatching percentages under different temperatures, food consumption, salt acclimatization, growth under combined effect of salinity and temperature, effect of food type on growth of newly hatched snails and examine samples of snail to detect the infection with parasites if present. The density of the snail was ranged from four to 13 ind. /m2 recorded during January - February 2015 and October 2014 respectively, while the mean density of egg masses was from two to nine egg mass / m2 recorded during April 2015 and October 2014. The statistical analysis showed that the temperature had positive correlated with density of each of snails and its egg masses. On the otherhand, there are positive correlation between the density of each snail and its egg masses. The snails, which had been collected during the study period, were 19 - 68 mm in length, these measurements were classifying into five size classes. The size class 35 - 45 mm was dominanted for nine months, compared with the size class 55 - 65 mm that had less occurrence.The diameter of eggs varied from 2.5 - 4 mm. The 25°C is the most suitable temperature to get a high percentage of hatching and a short period of embryonic development. There was no significant correlation between the weight of the female and the number of its egg masses.The feeding experiment showed that the amount of food consumed lettuce mild during the study period 30 days by one individual ranged from 3 - 29g. The results of the acclimatization was referred to the ability of all size classes' snails to tolerate the low salinity 2.5 psu with 100% survival percentage, while the snails of size classes at least 10 mm and 10 - 25mm were able to tolerate the salinity of 11psu with 10% and 50% respectivly survival.There are variable effects of the combination of temperature and salinity on growth of newly hatched snails for 9 weeks experiment, these effects were reflected on the weight, length and width, and the highest of these measurements were recorded for snails of 2.5 psu - 27°C combination, while the lowest one was recorded in 7.5 psu - 10°C. The lowest survival percentage was 5% recorded for the individuals of 7.5 psu - 27 and 32°C, compared with 90% of distil water - 17°C. On the other hand, the optimum growth was in 2.5 psu all temperatures, while the optimum growth was in all salinities, and temperature of 27°C.The experimental study of five types of food fresh celery, fresh lettuce, fish food, mixed food and animal protein)on growth of newly hatched snails for 9 weeks. Showed that the mean weight, length and width of snails were depending on the food type. The mixed food gave significant increase in growth 382.1 mg weight, 10.10mm length and7.58mm width compared with the other types of food.The highest survival percentage 95% was recorded for the snails fed on celery, lettuce and fish food. The present study on the snail P. canaliculata does not record any infection by the larvae of parasites

Control group : were intraperitonially (i.p) injected with 0.1 ml of normal saline.2 - Treated group 1 (T1) : were i.p injected with 0.1 ml of 6mg/kg of Dimethoate for a period of 30 days and represented as a low dose of the pesticide.3 - Treated group 2 (T2) : were i.p injected with 0.1 ml of 12 mg/kg of Dimethoate for a period of 30 days and represented as a high dose of the pesticide. The results of blood parameters in male mice showed a significant decrease in both of red blood corpuscle (RBC) count, hemoglobin Hb and Packed cell volume (PCV) of both doses (6,12mg/kg), and significant decrease in mean cell hemoglobin concentration (MCHC) in dose of 6mg/kg only as compared with control group. while in female, both of RBC count,PCV, mean cell hemoglobin(MCH) and MCHC were significantly decreased in both doses (6,12mg/kg), a significant decreased in Hb in dose of 6mg/kg in comparision with control group were recorded. The results of differential WBC counts of male mice showed significant decrease in total WBC counts in mice injected by both doses (6,12mg/kg),also the percentage of monocytes and granulocytes were significantly decreased in dose of 12mg/kg only as compared with control group, while the WBC count and the percentage of granulocytes were significantly decresed in female injected with 12mg/kg only of pesticide as compared with control group. In the male mice injected with two doses (6,12mg/kg). the results of current study explained decrease significantely in sperm count, and significant increases in percentage of malformation rate of sperm heads and tails , as well as, significant decreases in normal sperm count when compared with control group. The results of present study showed significant decrease in weight gain for male and female laboratory mice treated with two doses (6,12mg/kg) of dimethoate in comparision with the control group. The present data showed no significant differences in the level of liver enzymes Aspartate transaminase (AST) and Alkaline phosphatase (ALP) of male laboratory mice treated with two doses (6,12mg/kg), while significant decreased in the level of Alanine transaminase (ALT) enzyme with dose of 6 mg/kg only as compared with control was noticed, while significantely increased in levels of liver enzymes (AST and ALP) in female mice with two doses (6,12mg/kg), as well as,there was a significant increased in level of ALT enzyme with dose 6 mg/kg only when comparision with control. The level of urea and creatinine serum significantly increased whith two doses (6,12mg/kg), and there was no significant difference with dose of 6mg/kg when compared with control, also, the level of urea significantly increased in the serum of female mice with 12 mg/kg only, and there was no significant differences with 6 mg/kg as compared with control group. The results of histological section for some organs of laboratory mice showed occurrence of histopathological changes in the tissues of liver,kidney,lungs,spleen,testis and ovaries of mice injected with doses (6,12mg/kg), and The severity of the effects were dependent on dose, Histopathological findings of liver included degeneration and necrosis of some liver cells, blood congestion and explansions in the portal vein,central vein and hepatic sunsoids, as well as, the presence of hemorrhage in the portal area, infiltration of inflammatory cells in scattered area of it. In the kidney, histopathological changes showed degeneration of some tubular epithelium,while other cells where observed necrotic, sloughing and metaplasia of some tubular lining cells, as well as, congestion, hemorrhage and infiltration of inflammatory cells in the glumeruli. The histological examination of mice lungs were injected with two doses of dimethoate showed histopathological changes represented by the presence of edemas, infiltrations of inflammatory cells in different areas, hemorrhages and vascular congestion, as well as the occurrence of hyperplasia and swelling of cells lining of the pulmonary alveoli, causing narrowing cavities of those alveoli. In the spleen, the histological changes represented by occurrence of hypertrophy of the spleen nodules, expansion of blood vessels and decrease in the number of megalomultinucleated cells, as well as an increase in the cells of hematopoietic myloid tissue and presence of hyaline material, stained with pink color in the red pulp areas, especially around the spleen nodules. Injection with dimetoate caused histopathological changes in the testis and ovaries of laboratory mice represented by complete analysis of most spermatogenic cells in the seminiferous tubules,leading to decrease their numbers ,we also observed thickening of the basement membrane of some seminal tubule ,as well as vascular congestion and deposition of a live materials in interstitial spaces ,while the histological changes that have occurred in the ovaries included hyperplasia and vascular congestion in the stroma in addition to decrease number of ovarian follicles and corpora leutea.
