المستخلص: Asthma is a chronic inflammatory disease of the airways in which many cells and cellular elements play a role. Causes recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. These episodes cause airflow obstruction, often reversible either spontaneously or with treatment. The current study was conducted at the Labs of college of Education for pure science and Al - Hussein Teaching Hospital in Thi - Qar province, during the period from October 2014 to May 2015. The study aimed to investigate role of polymorphism of IL - 13 gene in patients with asthma and to evaluate their immune status by measuring the levels of some immunological parameter immunoglobulins ( IgE) by enzyme - linked immunosorbent assay (ELISA) and (IgG, IgM ) by single redial immune diffusion (SRID) and measure the levels of interleukins (IL - 6, IL - 17) in the serum using enzyme - linked immunosorbent assay (ELISA), the study included test phagocytic cells on phagocytosis (coefficient of phagocytosis) and the total and differential count of white blood cells .A total of 100 patients with bronchial asthma (68 females) and (32 males) whose age lies between 17 - 62 years have enrolled in this study. DNA was extracted and RFLP - PCR was performed by using primers specific for the gene IL - 13, the results showed the presence of mutations in a48 sample out of 100 patients with asthma at site 1112C/T after using restriction enzyme BstUI. the statistical analysis showed correlation between the occurrence of the disease and the emergence of mutation (C / T) in the promoter region of IL - 13 gene when compared with the healthy control in population of Thi - Qar province .When it was compared the patient group with healthy control group there was a high significant increase (P ≤ 0.001) in serum IgE, IgG of patients with asthma compared with healthy control group. And no significant difference in serum IgM of patients with asthma compared with healthy control group. Decrease coefficientphagocytosis was significantly (P ≤ 0.001) in all patients with asthma compared with healthy control group. Levels of interleukin (IL - 6, IL - 17) measured in serum of 60 a sample of patients with asthma, and in the serum of 20 samples from healthy control group. The results showed a significant increase (P ≤ 0.001) in the levels of these interleukins in the serum of patients with asthma compared to the control group.Also there was increased in the rate of counting the total of WBCs and differential cell lymphocytes, eosinophil, neutrophil, basophil, and monocyte (P ≤ 0.001) in patients with asthma compared with the healthy people in the control group.

المستخلص: Breast cancer is a complex and multifactorial disease resulting in abnormal cell growth that leads to malignant tumor formation.In this study we focus on mutations of breast cancer susceptibility genes 1 and 2 (BRCA1 and BRCA2), immunohistochemical evaluation of estrogen, progesterone, HER - 2 receptors, ABO blood groups , white blood cells and clinicopathological parameter ( age, breast feeding, family history and tumor site) .Eighty five blood samples were taken from patients who attended Al - Hussain teaching hospital and oncology unit in Al - Habboby hospital during the period (from August /2014 to April /2015) , fifty blood samples were collected from healthy women as a control group who attended Al - Hussain teaching hospital and divided into groups according to age, family history, age at first brith, breast feeding. For histopathological and immunohistochemical analysis fifty tissue samples were collected from patients with breast cancer who were undergoing surgical resection (mastectomy). Blood samples were obtained by venepuncture , using a 5 ml disposable syringe , and they were divided into three aliquots, which were 1 ml, 2 ml and 2ml, for collect serum, genetic studies and hematological parameters (leucocycte count and ABO blood groups) study. The tissue samples were collected from the 50 patients with breast cancer for histopathological diagnosis and for Immunohistochemical analysis (estrogen receptor, progesterone receptor and here2/nue) The total patients were divided according to their age in to five groups (30 - 39), (40 - 49), (50 - 59), (60 - 69) and (≥70 years). results of present study revealed that a highest incidence of breast cancer (41%) occur in the age oup between 40 - 49 years, there is a significant difference among patients groups (P ≤ 0.01).The results of our study showed that (77) of patients lactating and from those according to period of lactation we found that the highest percentage of patients (37.6%) were lactating for period between (18 - 22months) and the lowest percentage (10.38%) lactating for period between (1 - 6 month). Family history of breast cancer indicates a strong association with risk of developing breast cancer. The result of the present study revealed that the family history positive in 31 cases (36.47%), and 54 cases (63.52%) had negative family history of breast cancer.The results of present study showed that (41.5%) had first birth at age (20 - 29years), (23.37%) had their first birth in age group (15 - 19 years) and (30 - 39 years), and (9.09%) had first birth at age (≥40 years).Regarding the tumor site, we found that most of patients (50.5%) the tumor mass was located in the right side and (38.8%) cases the tumor mass were located in the left side.The DNA was extracted from blood samples by using Accupower® genomic DNA extraction kit. Each concentration and purity of all DNA samples have been measured by Nanodrop. Samples with a purity ranged from 1.2 to 1.8 have been enrolled in this study for the molecular detection of BRCA1/2 gene mutation in patients and control groups. Detection of BRCA1/2 gene mutation by multiplex PCR revealed that (185 del AG mutation in BRCA1 gene) was detected in 6 patients (7.05%) out of 85 cases with breast cancer, and (5382 ins C) mutation in the same gene was detected in 2 patients (2.35%). Regarding (6174 del T) mutation in BRCA2 gene was detected in 3 patients (3.52%). While this mutation was not detected in the control groups.Histopathologically, carcinoma was divided into 44 cases (88%) ductal carcinoma {from which 42 cases (84%) were invasive ductal carcinoma, and 2 cases (4%) were comedocarcinoma}, and 6 cases (12%) cases invasive lobular carcinoma. Results revealed that 2 cases (4%) were stage I, 13 cases (26%) were stage II, 24 cases (48%) were stage III and 11 cases (22%) were stage IV, also our results showed that the 2 cases (4%) were grade I, 23 cases (46%) were grade II and 25 cases (50%) were grade III. The results of immunohistochemical analysis for breast cancer samples showed that Estrogen receptors were present in 36 cases (72%), and 14 cases (28%) were negative, while Progesterone receptors detected in 27 cases (54%), and 23 cases (46%) were negative, on the other hand the expression of HER - 2/neu showed positive results in 28 cases (56%), and 22 cases (44%) were negative.Regarding the ABO blood groups, we found that most of the cases carry blood group A (40 cases, 47.05 %), and the lowest frequency was for blood group AB (7 cases, 8.23%).The results of the present study showed that leukocytes count, lymphocytes count, monocytes count, neutrophils count and basophiles count were lower in patients than the control group, with a significant difference (p value ≤ o.o1). While the eosinophils count was significantly higher in patients than the controls (p value ≤ o.o1).

المستخلص: recently Iraq where suffer from several crisis including diminished quantity and deteriorated quality of water resources, specially in southern provinces. This study was designed to show the extent of using non - traditional water resources such as sewage after its treatment with local alternative chemicals and using the resulting water in agriculture sector. Samples were collected from the terminal tank of waste water station in Al Nasiriyah ( Alhindia station) according to the criteria of United States Environment Protection Agency (USEPA, 1977) regarding the sewage properties including pH, EC, total dissolved solid(TDS), total suspended solids( TSS), CO2, Mg+2, Ca+2, Na+, CaCO3, Cl - , PO4 - , NO3 - , chemical oxygen demand ( COD), biological oxygen demand (BOD5). Moreover, we easured three trace elements ( Pb, Ni, Cd) as well as sodium adsorption ratio( SAR) and biological properties and bacterial contamination with fecal coliform bacteria. Physicochemical analysis of both sewage and tab water was performed. It was found that pH values were 7.37 and 8 for sewage and tab water , respectively. While the electrical conductivity for tab water was 8.01 ds / m compared with that of sewage water which was only 1.76 ds / m . TDS, TSS and CO2 for both sewage and tab water were (3780, 723) and ( 800 , 320) and (5.41, 1.23) mg/ L respectively. Results also showed that sewage water contain high concentrations of cations and anions as compared to tab water. Magnesium concentration was 469.42mg/L in sewage water and 100.1mg/L in tab water while calcium was 581.2mg/L in tab water and 60.8 in sewage water. Sodium concentration was 662.86 mg/L in sewage water and 186.3mg/L in tab water. On the other hand, water hardness and alkalinity were (3300 , 280) mg/L for sewage water and ( 2.40, 66.49) mg/L for tab water respectively .Results of this study also showed an increase in the concentrations of some ions in crude sewage water with respect to tab water. Concentrations ofchloride,phosphate,sulphate and nitrate in sewage water sample were 2496.31 Mg/ L,1.6 Mg / L , 1976 Mg / L ,3.67 Mg / L and for tab water were 226.8,0.7,108.48,0.6 Mg/L, respectively. Fecal coliform number was 2600 cell/100 ml in sewage sample and only 6 cell/ 100 ml in tab water. BOD5 andCOD values were 18, 167 Mg/ L for sewage water and 2.0, 6.0 Mg/L for tab water respectively Heavy elements also found to be elevated in sewage with respect to tab water , where the concentrations of Pb,Ni& Cd in sewage sample were 2.8, 0.8 & 0.004 Mg / L , while they were 0.09, 0.001 &undetected in tab water, respectively. On the other hand, sodium adsorption ratio SAR in sewage samples was 7 and in tab water was only 0.48.Laboratory experiments dealt with the following : 1 - It was used sand filters as a primary processing for waste water to remove pollutants prior to pass it through used filter upon incubating it for 14 days . 2 - in this study , it was selected four types of filters to remove contaminants and improve the quality of water is (water plant Ceratophyllum demersum, wood sawyer , , coal and Cladophora glomerta ). As it was used as filters either aprimary step in processing waste water through passing these waters as aby - pass step these waters on sand filter was used in this studay .3 - chemical , physical and biological characteristics of waste waters were studied upon passing it on the under - studying filters and also estimated the efficiency of removal Removal efficiency (%) of the components. 4 - Used of Some international Standerds and Iraqi specifications to evaluate the quality of water befor and after to pass it on filters for irrigation purposes. Some of criteria Such as (Kloke, 1980; WHO, 1995; US EPA, 1996; European Society, 1996 and Awasthi, 2000. ) were used to in the evaluation of soil contamination with heavy metals.This study reached to the following results : .The study concluded accrediting wooden sawyer + sand and water plant in recycling and reforming waste water and its capacity to remove pollutants, evaluation of quality of waste water and the treated water after passing through the filters under studay results indicated that all types of water inclusive the class (C4S1 ) which means high salinity water with afew of sodium element according to the classification of Laboratory US salinity. and water to cause toxicity problem in the study, and showed It results that candidates contributed to the removal of pathogenic bacteria from the treated water, and irrigation with waters passed through ceratophyllum dermersum L and sand filter leading treatment gave the highest dry to plant maize and two shoot and root weight, Result of statistical analysis showed that soils characteristics had a significant effect on of dry weight, concentration and quantity absorbed heavy elements in sections shoot and root to plant maize, was not for irrigation with treated wastewater impact on soil pollution with heavy metals and the results showed that the soils environmentally safe after relying on the Organization standards (WHO) and the American Environmental Protection Agency (US EPA).

A total of 310 samples (180 infant formula, 50 stool samples and 80 hospital environment swabs ), during the period from September 2012 to July 2013 were collected. Growth on Violet redbile agar and MacConkey agar was identified by cultural and biochemical tests and confermated by API 20 E system which revealed that : Only 22/310(7.09%)gave positive growth for Enterobacter spp. as following : 9/80 (11.2%) environmental swabs , 12/180(6.6%) infant formula and 1/50 (2%) stool samples. Diagnosis of the isolates appeared that E. cloacae was (15 ⁄ 22) while E . sakazakii (4 ⁄ 22) and E. aminogenus (3/22). Four E. sakazakii isolates were screened for their antibiotic resistance against 20 antibiotics of different classes using Kirby - Bauer disk diffusion method. The results showed that all the tested isolates were resistant to at least 6 antibiotics of which they were tested . In the present study four E. sakazakii isolates where screened for potential ESBLs production, they showed 3 (75%) isolates were potential ESBLs production ,but conformation of ESBLs production was detected by double disk synergism test and appeared that all the isolates were unproductive . Combined disk diffusion method was used for detection of metallo - β - lactamase - producing isolates, they were emplace each of imipenem and ceftazidame antibiotics with and without EDTA on Mueller - Hinton agar, because EDTA working to inhibit of metallo - β - lactamase. The results showed that the presence of EDTA does not affect the diameter of inhibition zone for the four isolates. Biofilm production was detected by spectrophotometric method .The four isolates were tested and appeared that 2(50%) were produced biofilm. The resistance of bacterial isolates to serum bactericidal activity was tested by the turbidmetric assay . All isolates were appeared able to resist to serum bactericidal activity, while Agglutination of erythrocytes was tested under the microscope and showed 3/4(75%) were positive. In the present study E. sakazakii were evaluated enterotoxin production. All the isolates showed positive for enterotoxin production. Results of treating suckling mice with enterotoxin showed acute clinical signs appeared depression, slow movement and signs of weakness. Significant macroscopic finding showed in mice treated with enterotoxin the stomach was distended and enlarged with thick corrugated mucosa but no significant changes in intestine. Pathological changes in the stomach appeared as loss of normal architecture of mucosa and glands, multiple foci of degenerative cells, reactive epithelial surface with thickening wall, pseudo - metaplasic changes and superficial epithelial injury. The intestinal changes showed nonspecific pattern of damage to surface of epithelium .Complete loss of architecture of glands and mucosal epithelial , superficial epithelial discontinuity , ulcer and non - specific reactive epithelial surface.

A total of 554 (468 clinical and 86 environmental samples) during the period from October 2013 to March 2014 were collected. Growth on blood agar, MacConkey agar and E.M.B agar was identified by cultural, morphological and biochemical tests and confermated by API 20 E system which revealed that : 45 ∕ 554 ( 8,1%) gave positive growth for Klebsiella spp. as following : 2 ∕ 48 (4.1 %) fromburns , 7∕ 40 (17.5 %) from wounds, 29 ∕315 ( 9.2%) from urinary tract infections, 4 ∕ 25 (16%) from respiratory tract infections, 3 ∕86 (3,4%) from hospitals environments.All the 45 isolates of Klebsiella spp. were screened for their antibiotic resistance against 15 antibiotics of different classes using Kirby - Bauer disk diffusion method. The results showed that all the tested isolates were resistant to at least 6 antibiotics of which they were tested, hence the isolates were considered to be multidrug resistant.The results showed that all of the isolates were found to be resistant to β - lactam antibiotic (ampicillin and amoxicillin) Disk approximation test and not production of ESBLs by these isolates.Combined disk diffusion method was used for detection of metallo - β - lactamase - producing isolates , it was emplace each of imipenem and antibiotic with and without EDTA on Mueller - Hinton agar , because EDTA working to inhibit of metallo - β - lactamase . The results showed that there was no effect for EDTA on the diameter of inhibition zone in all isolates.All the 45 isolates were submitted to molecular detection of some ESBLs genes (bla CTX - M , bla CTX - M1) using PCR technique. The results showed that only 28 ( 62,2%) isolates were carried ) blaCTX - M or blaCTXM1) and 21 isolates were carried both genes (blaCTX - M and blaCTXM1).

المستخلص: Toxoplasma gondii is a unique intracellular parasite, which infects a large proportion of the world, population, but clinically uncommonly causes significant disease. The present study was performed for the first time in Thi - Qar province to estimate the prevalence of toxoplasmosis among university students. Blood samples were collected from 319 (111 males and 208 females) apparently healthy students, they have ages between (18 - 42) years attended from different colleges of Thi - Qar university (students of morning and evening study), during the period from October 2013 to April 2014.Enzyme linked Immunosorbant Assay (ELISA), was used to evaluate the presence of anti - Toxoplasma IgM and IgG antibodies and detection of B1 gene of T.gondii DNA by Real - Time Polymerase Chain Reaction (RT - PCR).The results indicated that 21.94% of students were exposed to positive for anti - Toxoplasma antibodies, 5.33% of them had IgM, 11.91% had IgG, and 4.70% had both IgM and IgG. Statistically, they were significant difference between them.There were a significant difference between males and females in total rate but not significant of antibodies pattern in them, which recorded 7.52% of males and 14.42% of females were positive for anti - Toxoplasma antibodies.The study demonstrated that no significant difference in infection percentages between colleges where students studied, although the highest seropositivity students was 47.83% in education sports college whereas it did not score any infection with toxoplasmosis in College of Education for Pure Science .The current study also showed that the highest positive percentage with T.gondii of male students was 28.57% in College of Engineering while the highest percentage with T.gondii of female students was 30.43% in College of sports education.The present study revealed that the acute infection of toxoplasmosis which presented IgM and both IgM and IgG was high at small age youngstudents (18 - 22) years while the chronic infection which presented IgG was high at old students (38 - 42) years.The present study demonstrated that seroprevalence of toxoplasmosis was significantly associated with close contact with cats. Although more students in the positive sample group eating undercooked meat but not significant difference between those 36.13% and other students who did not have this habit 13.5% has been discovered.The results showed the highest positive percentage samples at middle socioeconomic level was 24.10% while the lowest percentage at good socioeconomic level was 19.60% .The results showed that the highest positive percentage samples 31.0% at Refaee district whereas the lowest percentage was 19.78% as noticed at Naserya district.The present study demonstrated that seroprevalence of toxoplasmosis was significantly associated with presence of clinical symptoms (fever, headache, malaise, influenza) that may have a relationship with toxoplasmosis of infected students when compared with not presence clinical symptoms of those (p<0.05) they recorded 18.57% and 81.43% respectively.The present study revealed an association between blood group system and Toxoplasma infection with highest prevalence among samples of blood group A+ 30.65% and lowest prevalence in samples of blood group B+ 17.44% .The current study evolutes the rate of some blood parameters, in infected and non infected students, there was no significant difference observed in mean hemoglobin level (Hb), total count of leukocytes (WBCs), neutrophilis, lymphocytes, monocytes and basophilis numbers in both student . While significant differences were observed in mean of eosinophils number of infected students was more than number of non infected students.Moreover, mean of lymphocytes number recorded significant differences between infected and non infected females only.Besides the serological diagnosis of T.gondii, Real - Time PCR (RT - PCR) technique was used to confirm the infection with T.gondii by detection B1 gene of T.gondii DNA in the blood of students. Out of 319 students only 6.26% showed positive for toxoplasmosis among those 2.50% were males and 3.76% were females. The positive result in RT - PCR analysis were distributed on the patterns of the anti - Toxoplasma antibodies by ELISA test , Any positive blood samples with IgM, IgG and both IgM and IgG respectively have not been found whereas 20 positive cases of no anti - Toxoplasma antibodies.Real - Time PCR test in student's blood has advantages in detection of recent or active toxoplasmosis

المستخلص: The current study was performed to get the knowledge of seasonal and Reginal changes in concentration of some trace elements(Zn, Pb , Ni and Co) in sediment, water and aquatic plant (Ceratophyllum demersum) in the Euphrates River at Suq _ Alshuyoukh district, south of Iraq . The study was include some of the chemical and physical properaties for water (air and water temperature,turbidity, electrical conductivity,salinity,dissolved oxygen , biochemical oxygen dimand, pH,nitrate,phosphat also total organic carbon and sediment texture). The samples were collected from the river on seasonaly from Autumn 2015 to summer 2016. There are three stations were selected for the study , the first station was near by the tourist Alfadhliyah bridge, afertile farmland on both sides of the river. The second station was in Suq_Alshuyokh , it's away from the first station about 15 km , it's a center of boats which used for fishing ,agriculture lands and homes. The third station was located in stream of ALkermashiya which lieson snuffa_marsh (apart of the Hammar marsh) ,It's away from the second station about 11 km and it's near by villages and fertile farmland. The results of study showed that air temperature was ranged between (15.8 - 49.5)° C and water temperature was ranged between (13.8 - 48.7 ) °C . The highest temperature recorded in the third location during Summer. Turbidity concentrations ranged between (5.7 - 15.6) NTU. The electrical conductivity are ranging between (3920 - 8336) Ms/cm , and salinity of water was low (Oligohaline) ranging between (2.50 - 5.33) ppt and recorded the highest concentrations in the third station . the highest value of pH was (8.9) in the secondstation and the lowest value was (7.3) in the first location while the Dissolved Oxygen concentrations ranged between (3.1 - 8.45) mg/L. The biological oxygen demand (BOD5) was ranged between (0.35 - 4.5) mg /L. As for concentration of nitrates was ranged from (0.02 - 6.33) mg/L. and phosphate ranged between (0.01 - 5.8) mg/L. the total organic carbon as percentage was ranged between (0.48 - 3.1) %.while sediment texture was mixed from sand ,silt,clay,the percentage for the mentiond compenents was,(50%,20% and 30%)in station 1,(40%,10%,50%)for station 2 and (10%,20% and 70%) for station3Atomic absorption spectrofotometer was used to estimate four trace elements (Zn,Pb, Co, and Ni) .The concentrations of the mentionel elements in water dissolved phase were (2.86,5.87,1.63,0.51) μg /L,while their concentrations in particulate phase were (12.48,28.21,17.74,1.08) μg /gm dry weight respectively. In sediment the concentrations averages oftrace elements were (142.73,127.70,176.82,29.24) μg /gm dry weight respectively.In aquatic plant (Ceratophylum demersum) the concentrations averages of trace elements were (123.32,117.54,157.54,27.90) μg /gm dry weight respectively . It concluded that the concentration of studied elements in sediment more than their concentration in water (dissolved and particulate) phase and more than their concentration in plant (Ceratophyllum demersum), also all concentrations of trace elements were in the international acceptable values.

المستخلص: Toxoplasmosis is the general term for infection and disease in human and animal caused by a parasite called Toxoplasma gondii, this disease is prevalent among different categories of people , Heart disease patients are one of them. Because of the dormancy status of T. gondii, there is ambiguity and variation in the immunity of patients. This study aimed to investigate the immune status of heart disease patients infected with toxoplasmosis, to detect the prospective relationship between heart disease patients and T. gondii, and investigate the relationship between toxoplasmosis and risk factors which included gender, age, blood group, contact with cats, and habitation.One hundred fifty samples of blood had been collected at period from August 2016 till November 2016 from patients with heart disease, they lying or visit Heart Medical Centre in Thi - Qar province. According to gender, the patients divide in to (81 males and 69 females) with age ranging 18 to 82 years. Also one hundred samples of blood had been collected from apparently healthy persons as negative control ,dividing according to gender in to ( 55 males and 45 females) with age ranging 19 to 56 years . All samples of both subjects had been tested by ELISA technique to detect anti - Toxoplasma Abs (IgG & IgM) . While the positive samples with toxoplasmosis were tested to detect the level of interleukins (IL - 10, IL - 12 and IL - 17).The overall of seropositivity of anti - Toxoplasma Abs that scored by ELISA in the current study was 44% in heart disease patients are higher than those in apparently healthy controls 19%, and there was a significant difference between them. There is a significant difference between male and female, in the seropositivity of anti - Toxoplasma Abs that scored in controls, in male was higher than those in female. Presence of antiSummary toxoplasmosis Abs in all types of heart disease patients with significant difference among them, and the highest percentage of anti - toxoplasmosis Abs in Mitral stenosis( MS) was 55.8% , and the lower value was 30.3% in Myocardiopathy.There are significant differences between the age groups and the percentage of anti - Toxoplasma Abs in heart disease patients with highest value was 63.2% at age group of 61 - 75 years, and the lowest one was 26.3% at age group of 15 - 30 years. While no significant differences between the age groups and toxoplasmosis in apparently healthy controls with highest value was 19.5% at age group of 31 - 45 years, and the lowest one was 8.6% at age group of 15 - 30 years.The results demonstrated that seroprevalence of toxoplasmosis was significantly associated with close contact with cats. The percentage of seroprevalence anti - Toxoplasma Abs in heart disease patients and controls inhabited rural area was 52.5% and 32% are higher than those inhabited urban area was 34.3% and 6% respectively. Some blood parameters were estimated of both subjects infected and non - infected with toxoplasmosis. There was high significant difference at p≤0.05 observed in mean ratio of eosinophil’s number between infected and not infected subjects with toxoplasmosis in both subjects. While there was no significant differences in mean ratio of total count of WBCs. Moreover, mean of lymphocytes number recorded significant differences betweeninfected and non - infected heart disease patients only. The blood group phenotypes of the infected heart disease patients and controls highlight the role in toxoplasmosis infection and the AB blood group characterized by the highest significant percentage of infection. The results of interleukins appeared high mean levels of IL - 12 82.85 pg/ml in heart disease patients infected with toxoplasmosis when compared with control 60.97 pg/ml, and there was significant difference between them. While there was no significant difference in IL - 10 and IL - 17 in both patients and controls. The results also showed decreased level of IL - 17 in patients with heart disease. The increased level of IL - 12 in patient with heart disease infected with toxoplasmosis indicate to the activity of cell mediated immunity in those patients and may be lead to provoke an inflammatory status in the heart valves and muscle then worse heart disease to be sever and need complicated treatments

المستخلص: The current study was conducted in Thi - Qar province to investigate of Toxoplasma gondii prevalence among renal dialysis and cancer patients by using Enzyme Linked Immunosorbent Assay test and also the study determined of some factors that may affected that may affected the prevalence of infection, such as age, sex, marital status, place of residence and the contact with cats and a number of chemical dosing that exposed to it cancer patient or the number of times the dialysis for renal dialysis patients.One hundred blood samples were collected from renal dialysis patient and one hundred samples others were collected from cancer patient from two hospital AL - Hussein Hospital and AL - Habboubi Hospital for the period from the beginning October 2015 to the end of the month of March 2016 and prepared a questionnaire form for each person to get their information, as well as the collection of 50 blood samples from (healthy) as control group . .The results of the current study showed that the prevalence of toxoplasmosis in Thi - - Qar province in both renal dialysis and cancer patients and control group were 28% and 36% and 24% respectively. recorded results of Enzyme Linked Immunosorbent Assay ELISA test results for a positive antibody IgG in both renal dialysis and cancer patients and control group 25% , 30% , 22% respectively. As for the IgM antibody study did not record any positive result in both categories of the study (dialysis and cancer) only control group was 2%. The result of IgG & IgM together in renal dialysis and cancer and control group 3%, 6%, 0% respectively. .The highest infection prevalence were detected in renal dialysis in the age group (40 - 49 years) amounted (26.67%) and less infection in the age group (60> years) with percentage of 23.08% . As for cancer patients, the highest infection prevalence in the age group (50 - 59 years) was 53.85% and were less infection in the age group (30 - 39 years) amountin 14.29%. .The current study recorded there is a significant differences at level of P <0.05 in infection prevalence accoriding to gender for renal dialysis patients as it was infection prevalence in males 35.18%, while in the females the infection prevalence was 19.56%. As for cancer patients the study recorded significant differences P <0.05 where the infection prevalence in females were highest compared to males where it was 38.59% and 32.55% respectivelyThe study did not show any significant differences P> 0.05 for the infection prevalence according to contact with cats in renal dialysis patients but the study found significant differences between married and unmarried where the infection prevalence among married 25.84%, while the unmarried 45.45% .The infection prevalence were in the City highest 29.27% compared to countryside which amounted to 22.22%, the study found that the increase in the number of times the dialysis increased incidence of infection prevalence it was 25.53% for patients who conducted the dialysis treatment more than six times and 16.66% for patients who have less than six times. In cancer patients, the study observed significant differences P <0.05 for the contact with cats and it was highest infection prevalence in the city amounted to 45.21% compared to countryside 11.11%. and recorded a high infection rates at married 37.90% either at unmarried did not show they have no infection by parasite. For factor chemical dosing show high infection rates in patients who have been exposed to more than one dose of a chemical 37.63% As for those who were not exposed to any chemical dose was ratios have 14.29% .and wasblood type B + higher infection in renal dialysis patients 40.74% either in the cancer patients were O+ highest amounted to 58.62 %The results of the blood Parameters which conducted for infected males by toxoplasmosis and non - infected had not noticed a change in the hemoglobin for both categories. As total count and differential white blood cells the study did not record significant differences in the renal dialysis patients except neutrophil blood cell was observed height in infected males than non - infected . as for Cancer group was a decrease in the total number and differential white blood cells except acidophilus did not record any change in its level. As the females the study results were that there was no significant difference for both renal dialysis and cancer patient except Lymphocyte found decline in infected than non - infected for cancer patients .showed the results of the current study for standards biochemical that there are no significant differences P <0.05 for renal dialysis and cancer patient in the case of urea, creatinine, the study do not found any effect of toxoplasmosis on the rates of both urea and creatinine. As albumin was observed to high at dialysis patients and low at cancer patients at infected with toxoplasmosis compared to non - infected either control group the study did not reported significant differences for urea and creatinine and albumin. either liver function the study did not find change in the level of liver enzymes (AST.ALT) in dialysis and cancer patients and control group (healthy) .The presnt study recorded there is no significant differences in lipid profile (HDL, LDL, VLDL, Cholestrol, Triglyceride) at infected and non - infected in renal dialysis goup either cancer patients was observed high (HDL, VLDL, Cholestrol, Triglyceride

المستخلص: The current study was conducted for the period from September 2015 until August 2016 in college of Education for Pure Sciences - University of Thi - Qar, this study aimed to fallow the embryonic lung development and evaluate histological changes in embryos's lung development when pregnant mice treated with different doses of Dexamethasone (Dex) and evaluate Alpha - fetoprotein (AFP) levels were evaluated as an indicator for congenital malformations. Sixty pregnant mice were randomly divided into four groups and each group contain 15 pregnant mice. The members of each group were given specific dose of Dex and at different time periods, while the control group injected with a solution of Normal Saline 0.9%.All animals received doses used by tail intravenous injection until the end of the time periods specified .Blood samples were taken for the purposes of biochemical parameters account as well as the collection of samples for histological study .The treatment of animals under the same conditions were determined with a dose based on body weight, according to what was stated in the pharmaceutical constitutions where's the therapeutic dosage was 0.002 mg \2mg (0.1mg.kg from body weight ). We used another two concentrations from drug ,one less than the therapeutic dosage (0.05mg \kg from body weight) and another more than the therapeutic dosage (0.2mg \kg from body weight ).The results have showed that was a negative effects on mice embryo's body weights and the lengths increase with increasing of number and doses concentrations. The using of different doses of Dex also showed various changes in general external morphological features and congenital malformation in embryos of treated mothers included : Death of embryos ,placenta damage ,neural Tube Defect ,Trunk Torsion ,Headhemorrhage, Brain hypertrophy ,Liver Hypertrophy ,Letter C Shape Embryos, swelling ,Convoluted Tail ,Short nostril and limbs, curved head, Wrinkled skin ,Crooked pave ,Short toes ,Seal legs appearance, Oedema ,absent fingers and eyelids ,Tail congestion and Bulging eyes. Histologically microscopic examination showed histological changes with varied severity and appearing between different sub experimental group compared with the control group.Rapid elongation in lung bud, advancing in lung development, the lung asflower appearance, Loosely lung mesenchyme ,necrosis in lung tissue ,mucus hypersecretion, elongation in epithelial air ways,epithelial Hyperplasia ,mesenchyme looks as butterfly in appearance in some parts ,thinning of alveolar walls ,thinning of the interstitialmesenchymal lung tissue ,elongation of developing alveolar septa ,free alveolar septa. Alfa - fetoprotein (AFP) levels showed different concentrations value in correlation with congenital malformations .when the (AFP) value was high there were neural tube defects and advancing in the lung development while they were low in normal lung development and in brain hypertrophy.

المستخلص: The present study includes the isolation and identification of some mycoflora from 40 soil samples in six places ( Remnants of fat - born, parks, edges of the river, animal wastes, sewage and rubbish) during October 2015 - January 2016 in Nasseriya City, Iraq. According to different environmental factors, the isolated genera were Aspergillus, Penicillium, Mucor, Rhizopus, Cladosporium, Sepedonium chrysospermum, Alternaria chlamydospora, Bipolaris, Chrysosporium, Candida albicans, Rhododendron flavum, Humicola, Geotrichum candidum, Fusarium and Acremonium. Three isolation methods were used. Dilution method, direct plate method, alcohol and heat treatment technique using the cultural media viz. Potato Dextrose Agar ( PDA), Sabouraud Dextrose Agar (SDA) and Potato Carrots Agar (PCA). Aspergillus represented the highest fungal isolates which represent 62 (37.12%). followed by Penicillium with 47 (28.14%), Mucor 22 (13.16%), Rhizopus 15 (8.98%), Cladosporium 6 (3.59%), Sepedonium chrysospermum and Alternaria chlamydospora, 3 (1.80%), Biopolaris, Chrysosporium and Candida albicans with 2 (1.20%), and finally Rhododendron flavum, Humicola, Acremonium, Fusarium and Geotrichum candidum recorded the lowest fungal isolation with one isolate for each (0.60%). The study was aimed to isolation of Penicillium from soil and assay its antibacterial activity. The results showed that dilution method gave a best fungal growth in comparison with direct plate method and alcohol and heat treatment technique in 25 ºC and pH = 6. PDA appeared as an optimum medium for isolation in comparison with other media such as SDA and PCA. The preliminary results showed that Penicillium sp. exerted antibacterial activity against Gram positive and Gram negative bacteria; Therefore, this fungus was used for production of antibiotic on Potato Dextrose Broth (PDB) medium. The optimum conditions were obtained at pH = 6, incubation temperature of 25 ºC and shaking rate of 180 rpm for 7 days to fermentation. Ethyl acetate was a good organic solvent to extraction of antibiotic which produced (3g/L) as white to creamy crystals. The characterization of the antibiotic product after extraction and purified by chemical methods included Thin Layer Chromatography (TLC) test, Nuclear Magnetic Resonance (NMR) Spectra and Mass Spectra. The Minimum Inhibitory Concentration (MIC) for clinical bacterial species was 1 - 10mg/ml.The PCR method used in this study utilized Internal transcribed spacer (ITS1 - 4) as a primer for identification of isolates. Two PCR products of the targeted gene of Penicillium chrysogenum isolates which locally named as (Penicillium chrysogenum F1 and Penicillium chrysogenum F2) were selected and subjected to partial DNA sequencing for the ITS gene to follow up the possible molecular relationship between these local isolates and what recorded globally in Genbank.

These insects included two species : papatasi and sergenti which belong to the same genus ( phlebotomus ) the number of the first species insects was more than of the second species. The number of the first species reached 85.90% while the number of the second species was 14.04% . The inset had been classified in transmitted diseases center in BaghdadThe insects have been found in the whole areas of the studying except the species sergenti which has been not found in the area of AL - majer AL - kabber . There are two peak spread times of these insects : The first is through out October and the second is the through out may . Concerning the relationship between the spread of these insects and the occurrence of Leishmaniasis positivewhere the infestation by this disease began on September November and December and the peak spread is recorded on January on the country of the inset occurrence where it begins at spring and the beginning of autumn . The spread of these insects was in flounced by the environmental factors such as temperatures and humidity . The flagellated promastigotes of leishmania parasite were not found during the anatomy of a lot of insects.Four chemical insecticides were used to control these insects where the effect of the insecticides (snake) was the strongest for killing these insects.515 infection of Leishamaniasis has been recorded in Maysan province at proportion of 506 cutaneous infestation and 9 visceral infection respectively .The rate of skin infestation was high in age groups between (1 - 10 ) year in comparison with another age groups.Concerning the types of ulcer ,the dry ulcer were dominant and the number of dry ulcers was 873 while wet ulcers were 100 concerning the diameter of the ulcer the higher infections occurred at diameter of 1 Cm which reached 873 infection . The number of patients infected by one ulcer was the highest which reached 301 infestation.The number of dry infestation in the cities was higher than in rural areas on the contrary of wet infestation . concerning the distribution of skin infestation on the body areas the higher ratio of infestation occurred in higher and lower extremities which reached 344 at proportion of 68.57%.The infestation of skin Leishmaniasis has been concentrated in the center of province which reached 334 at proportion of 66.07%.Concerning the months of the year , the majority of skin leishmaniasis was on January which reached 137 at ratio of 27.66%most of visceral leishmaniasis occurred in the patients of blood group type O proportion of 33.33% .The infection of visceral Leishmaniasis in males was higher than of females and the highest than and the highest infection of visceral Leishmaniasis was in age groups between (1 - 3) years and also the number of visceral Leishmaniasis infestation was the highest on January . Kumait areas is characterized by the presence of the highest visceral Leishmaniasis infestation.

المستخلص: Burn injuries are considered as health problems that may sometimes lead to rapid death. Bacteria are considered as the most important causes of microbial infection associated with burns. In present study, 75 clinical samples were collection from patients with burns for the period from October 2015 to June 2016 from the lobby burns in Sadr Teaching Hospital in the Maysan Governorate, these burn swabs revealed 56 bacterial isolates, 41 (73.21%) were Gram - negative bacterial, distributed of (35.71%) Pseudomonas aeruginosa, (28.57%) Klebsella Pneuomonia, (3.57%) Escherichia coli ,Enterobacter (5.35%). On the other hand 6(10.71%)were Gram - positive bacterial. out of 75 burned swabs, 84% revealed a single pathogens and 16% shown a mixed bacteria. On the other hand, Antimicrobial susceptibility for the bacterial burn isolates revealed that P. aeruginosa was resistant to routine tested antibiotics, like Amoxicillin, Gentamycin and Tobramycin in 100%, While was resistance to Ciprofloxacin 85%, while most P. aeruginosa was sensitive to Ceftizmiden in 50%. Results also showed that Staph. aureus was resistant to Gentamycin, Tobramycin, and Levofloxacin in 50% respectively.Depending on the rate of injury burns microbial and resistance to antibiotics used, p.aeruginosa and Staph.aureus isolated from the burnswere chosen and study their role in the events of infection, experimental burns, and for this purpose has been the use Albino mouse male as a model for a pilot study for pathogenesis and progress associated with the infection of the disease bacterial burns. (33) male mice were divided into tow groups, the first group(24) mice were burned (deep dermal second degree) and infection by 0.2X108 cfu kg of elected isolates, the route of infection was subcutaneously and scratching within burned area. In the second group six were infected without burn, which was considered as positive control, while in the thirdgroup three mice were burned and injected by 0.2ml of normal saline and consider as negative control .the first group was subdivided into two subgroups (12) mices for each burn dominant pathogens, then divided into subgroups each of six mices and following up (3,7, days intervals post infection process). P.aeruginosa burned mice group, shown skin infection more progressive and more severity in comporning with group infected by Staph. aureus, In addition, they were significant increases in the body temperature of all infection burned mice group(p.value)compared with those pre - infection process. Reisolation of bacteria from infection mice organs revealed, that high percentages in experimental p.aeruginosa burned model comparison with Staph. aureus.Diagnosed bacterial isolates by API 20and Vitek compact system, in addition to molecular diagnostics using PCR technique for the detection of 16S rRNA gene, All isolates showed a positive result of this gene. The amplified 16S rRNA gene seguence was compared with the seguence in NCBI seguence database.the bacterial strain identified as P.aeruginosa EPSI. This study reflects the usefulness of sequence analysis of the 16S ribosomal RNA gene in identifying bacteria and determining bacterial diversity. Various techniques that are based on utilizing the 16S rRNA gene are discussed. Of critical importance is the use of massively parallel sequencing to study bacterial diversity. Through massively parallel sequencing which is replacing traditional methods of bacterial identification; various bacterial habitats are surveyed to compile their species compositions.

The specimens of sputum were 130 which collected during 1/ October /2015 until 1/May/2016. The study showed that 85 of the collected specimens appeared as positive results which were 65.38% of the ratio in which the females ones were 21 (46.67%) specimens while 64 (75.29%) for males. In addition that, the highest ratio of the positive results was recorded in the ages of 61 - 70 years, followed by 31 - 40 years which were 32.94% and 15.25%, respectively. Totally, 106 isolates of the isolated opportunistic fungi appeared from the positive specimens. Through using morphological methods and molecular techniques, this study showed the first rank of the isolated fungi was Candida spp followed by Aspergillus spp, and Penicillium spp which possessed ratios of 49.41%, 38.32% and 21.17, respectively. According to the species, the first ratio of the isolation was Candida albicans followed by Aspergillus falvus, as 36.47%, 12.94%, respectively. Fifteen fungal isolates of the present study were recorded in the Gene Bank of NCBI. In this study, the extracts of Allium sativum were separately obtained by using four organic solvents (ethanol, acetone, methanol and water) and three concentrations (50%, 70% and absolute) of each solvents except water. Four concentrations of each extract were tested against 11 species of the isolated fungi in which the water extract gave the best value of the bioactivity including highest inhibitory value (60 mm) against Penicillium notatum by using 400µg\ml compared with the extracts of ethanol, acetone, and methanol. The bioactivity of Allium sativum extracts of each solvent was done against the tested fungi in comparison with Amphotericin B, Nystatin and Miconazole in which two of them produced the different bioactivities while Miconazole had no effect. The blood cytotoxicity of the crude water extract was performed against red blood cells and it did not appear any hemolysis. The chemical tests and Gas Chromatography (GC) revealed that the water extract contains alkaloids, phenols, flavonoids, terpenoids, tannins and carotenes in addition to sulfur formations, such as allicin as well as aromatic compounds.

All those individuals were suffering from diarrhea and abdominal pain. This study included the microscopic identification of Entamoeba Spp. using direct wet amount and concentration techniques in order to diagnose both Trophozoite and cyst stages of the parasite. The result revealed that 1050 (26.86%) of the collected samples were infected with Entamoeba Spp. Out of these infected samples, 80 were randomly selected for further confirmation by conventional PCR and 18S rRNA. Using this method, 28 (35%) was recorded to have Entamoeba Spp. Positive samples from conventional PCR were further examined by Nested PCR for species specific identification. The result of this method showed the presence of two species, E. histolytica (39.29%) and E. dispar (39.29%).Positive samples for molecular examination (28) were then examined by Real time PCR in order to verify and confirm the molecular results. Two probes were used, Histolytica - 96 Tfor E. histolytica and Dispar - 96 T for E. dispar. A significant difference was observed between two methods. E. histolytica was found to be higher percentage followed by E. dispar and then Entamoeba Spp., 53.57%, 39.29% and 7.14% respectively. The Real time PCR reported mono - infection with E. histolytica in 45.5% and with E. dispar in 27.2%, whereas reported mixed infections by both parasites in 27.3%. Red blood cells (RBCs) were detected in 80% E. histolytica positive samples and in 54.55% E. dispar positive ones.The environmental factors and their correlation with Entamoeba Spp. prevalence were also included in this study. The infection prevalence based on the seasonal variation showed significant differences P≤ 0.05. Summer recorded the highest infection prevalence whereas the lowest was in the winter, 37.06% and 14.14% respectively. Regarding the infection in age groups, the highest percentage (30.5%) was recorded in under 3 years old group and the lowest (17.13%) was found in above 10 years old one. However, no significant difference P≤ 0.05 was observed between these age groups. Furthermore, no significant differences were recorded betweenpatient’s sex.

المستخلص: This study included 3 stages. In the first stage, Toxoplasma gondii was isolated from aborted women placenta who visited Bent Al - Huda hospital and Al - Shatra hospital after confirmation of the prescence of parasite by impression smear method. Then parasite uspension injected 0.3 ml which contain 100 cyst intraperitoneally (174 rat) to 87 male and 87 female rats, inaddition to control group 30 rat (15 male and 15 female). After 10 days of injection, diagnosed the acute infection by Real - Time Poplymerase Chain Reaction(Real - Time PCR) and showed 97.70% (170 infected rat and 4 noninfected rat) , in male 96.55% (84 infected rat and 3 noninfected) ,in female 98.85% (86 infected rat and 1 noninfected) . After 2months of infection 84 animals (42 males and 42 females)were sacrificed, dissected (brain, testis and ovary ) were isolated to confirm the occurance of chronic infection with the using Real - Time PCR. The incidence of infection was 100% in brain males and ovary females and recorded 71.43% in testis and 90.48% in brain females. So diagnosed infection by impression smear method, identified the amount of DNA of the parasite T. gondii by using Real - Time PCR. The use of the remaining number of animals within the following experiments.The second stage included effect of experimental Toxoplasmosis infection and some drugs on fertility 168 rat (84 male and 84 female). Animals were subdivided into 6 groups for each group included 14 rat : (First group) non infected treated by DMSO, (Second roup) non infected treated by Sulfadiazine, (Third group) non infected treated by Pyrimethamine, (Fourth group) infected treated by DMSO, (Fifth group) infected treated by Sulfadiazine and (Sixth group) infected treated by Pyrimethamine.The current study results revealed prominent effect of T. gondii infection on the hormonal level in both males and females. T. gondii infection induced significant decline in Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH) and Testosterone levels in nfected male compared with non infected males treated by DMSO. Sulf. and Pyr. treatment significantly elevated the level of these hormones (P <0.01) in infected males compared with fourth group similar to levels its in first group. Toxoplasmosis in female rats significantly decrease FSH, LH, Estrogen and Progesterone levels in compared with first group, while treating of infected females with Sulf. and Pyr. didn,t improve the declined levels of these hormones in infected and noninfected females comparedwith fourth and first group, respectively.The study showed that Toxoplasmosis in male rats induced significant decline in the sperm count in the epididymal cauda, sperm viability and relative weights of male sexual organs with an increase in sperm malformation ratio in infected male compared with first group. Treatment with Sulf. and Pyr. in infected male significanthy elevated the sperm count and viability (P<0.05), compared with fourth group. Sulf. didn,t induced further significant changes, but Pyr. induced further significant increase in sperm malformation ratio in infected (P< 0.01) and non infected (P<0.05) rats. The study also revealed that Toxoplasmosis significantly decrease the relative weight of ovary and uterus compared with first group, while treatment with Sulf. and Pyr. increased the declined relative weight of the ovary and uterus in the infected females.Testicular histological section of Toxoplasmosis infected male rats treatment with DMSO showed vacular degeneration of spermatogonia and spermatocytes. The seminiferous tubules revealed sever degeneration, shrinkal, necrosis, hemorrhage. Seminiferous tubules lumen contained little amount of sperm with appearance of gaint cell, polymorphonuclear leukocytes and exfoliated cellular debris. Metamorphosis and disintegration of the tissue between the seminiferous tubules was also observed compared to the first group that showed complex histologically intact while testes sections of infected rats treatment Pyr. and Sulf. showed improvement by removing histocompatibility damage caused by the parasite infection.The epididymal sections of T. gondii infected rats treatment with DMSO showed infiltration of mononuclear and multinucleated gaint cell. Sections also showed hyperplasia of duct lining and contained tissue cyst of T. gondii. All these changes were improved in infected males treated by Sulf. and Pyr. Ovary sections of the infected females treatment with DMSO compared with first group revealed decreased primary and secondary follicle increased follicle atresia. Histological sections of ovary females showed in the fifth and sixth group to increase the number of primary and secondary follicles and decreased number of follicle atresia compared overian sections for the fourth group. Uterine sections of the infected females treatment with DMSO showed hypertrophy, increase endometrial thickness and myometerium, increase polymorphonuclear cell infiltration, fewer glands and congestion of blood vessels compared with first group. Histological sections for ovary females of the fifth and sixth group showed changes but less severe than is present in the fourth group.In third stage from studying Toxoplasmosis on fertility parameters of male and female rats, 84 rat(42 male and 42 female) which showed the results of the current study, when paired fertilized healthy females by males is infected and infected of T.gondii treatment with Sulf. , Pyr. and DMSO, and inversion, there is the effect of the parasite and used drugs the percentage of getting pregnant and pregnancy size and rate of embryos weight and placental weight and increase the proportion of fetal resorption and the proportion of early loss of embryos in fertilized healthy females by males five groups compared to the first group.Based on that conclude from the study that the infection of parasite T. gondii had negative effects on the fertility of male and female, and that all of thePyr. and Sulf. were not honest is the other of the impact on reproductive functions.

المستخلص: The dye sensitized solar cell (DSSC) is one of the photochemical electric cells, which consists of the photo electrode, dye, electrolyte, and the counter electrode. The advantage of DSSC is the low cost of the solar energy conversion into electricity because of inexpensive materials and the relative ease of the fabrication processes. In this work, titanium dioxide (TiO2) films as a photo electrode were prepared from anatas titanium Oxid (TiO2) nanoparticles and deposited by doctor blade method on fluorine doped tin oxide (FTO)coated glass substrates. After the process of deposition that including the prepared samples in the oven, the temperature raises from room temperature (R.T) to set up to around 400°C. Half an hour later, the temperature started to decrease to reach theroom temperature (R.T) . Multi - walled carbon nanotubes (MWCNT)used as a counter electrode instead of platinum(Pt),where prepared by spray pyrolysis technique (SPT) at 300°C,10 sec as spraying time ,and 60 sec stopped time. In the next step, Preparing the dye solution at room temperature then placed TiO2 electrode in the dye solution for 24 hours in the dark .The last step is collecting two electrodes one over the other leads to build a solar cell. Then a mixture electrolyte about(0.6 M 1 - methyl - 3 propoylimidazolium iodide (PMII) + 0.1 M LiI )is dipped onto the surfaces of both (FTO glass/TiO2NP/D149/PMII and MWCNTs/FTO)glasses .The thickness about (400nm) and the films are prepared under various deposition conditions in order to understand the effect of the temperature on the cell properties and to specify the optimum condition. X - ray diffraction (XRD), scanning electron microscope (SEM) are used for the structural analysis.Raman scattering spectrum used to determine the type of material CNTs used for DSSCs fabrication , Fourier transform infrared spectroscopy (FTIR) used for description as an analysis for system chemical structure of the atoms. UV and visible spectra have been recorded as a function of wavelength in the range (200 - 1000 nm) in order to study the optical properties such as reflectance, energy gap of allowed and forbidden direct transitions, extinction coefficient, refractive index, and dielectric constant in real and imaginary parts. It has been found that all the investigated parameters are affected by the sensitizer dye in the visible region of the spectrum .Finally I - V characteristic curves of the fabricated cell were measured and studied, this cell shows highest photovoltaic performances to date as Solid state dye sensitive solar cells

المستخلص: Natural radioactive materials (NORM) that accompany oil and gas production from a real problem for the environment and the people. These radioactive substances can from a significant threat to workers in the field of crude oil if the concentrations exceed permissible limits. Natural radioactivity due to U - 238, Th - 232, Ra - 226, Ra - 228 and K - 40 in crude oil samples collected from al Gharraf oil field in Thi Qar province, south of Iraq. 15 wells were selected to take crude oil samples from this field. were measured using gamma ray spectrometry based on scintillation detection 3 x 3 inch NaI (Tl).The radioactivity concentrations of U - 238,Th - 232,Ra - 226,Ra - 228 and K - 40 values in the studied oil samples ranged (0.92 - 5.02 Bq / kg),(1.42 - 5.27 Bq/ kg) , (0.91 - 5.81 Bq / kg) ,(1.56 - 4.52 Bq / kg) and (60.45 - 138.88 Bq / kg) respectively. The equivalent concentration for each of Ra - 226 and Th - 232 and K - 40 has been calculated for all samples and was found to be between (7.60 - 24.04) Bq / kg , (5.39 - 16.98) Bq / kg and (98.78 - 313.10) Bq/Kg respectively.The absorbed dose for these concentrations were calculated using three equations supported by ICRP, UNSCEAR and BECK and we found that the absorbed dose according to ICRP, UNSCEAR and BECK for all samples ranged between (1.378 - 5.675) , (3.85 - 11.00) and (3.881 - 11.496) respectively. The calculated values of the annual effective dose rate and excess lifetime cancer risks (ELCR) were between and (0.591 - 2.436591 ), respectively.The external and internal hazard index also calculated and found ranges between ⁄ and (0.023 - 0.081 ⁄ ), respectively. The results obtained indicate that concentrations of radioactive elements targeted in this study were within safe limits despite the variation in the concentration values between samples. We therefore conclude that the natural radioactivity due to U - 238,Th - 232,Ra - 226,Ra - 228 and K - 40 in crude oil samples collected from al Gharraf oil field in Thi Qar province poses no risk to workers according to standards set by International Commission onRadiological Protection Publication (ICRP60),World Health Organization(WHO)and United Nations Scientific Committee on the Effect of Atomic Radiation (UNSCEAR).

المستخلص: The performance of passive Q - switching with intracavity laser system to generate high power pulses have been investigated .The considered laser system consists of Nd : YVO4 , Cr4+ : YAG, and BaWO4 as a active medium, saturable absorber material, and Raman medium respectively to generate high power pulses . A computer program has been employed to solve the rate equations which are simulates the system performance numerically by Rung - Kutta - Fehelberg method. So, the results of the numerical solution have been utiliza to calculate the photons losses behavior in order to study the effects of these losses in the system performance.Raman spontaneous scattering factor ( ) sp k effect on high power pulses characteristics has been studied. There is a small increasing in the duration of the passive Q - switching pulse and stability in duration of stokes pulse when the factor ( ) sp k become high value. According to the current study, the reason of this behaviour is related to the small increasing in the falling time of passive Q - switching pulse and the semi stability in the falling time of passive Q - switching pulse . So, the mentioned aspect demonstrates the increasing in the pulses energy. The study explain that as an outcome high density of the pulses photons .Also the study shows the power of pulses is increasing with Raman spontaneous scattering factor value.In the study aspect which concern the losses behaviour in term of Raman spontaneous scattering factor, the study shows that the decreasing in the final value of total photon loss with Raman spontaneous scattering factor. The study related that to decreasing which occur in the density number of the ground state of SAM ions , that lead to decrement in its absorption activity, this is dominators of the increment in the excited stateof SAM absorption activity according to the difference values ofabsorption cross sections of levels.Output coupler mirror reflectivity on Raman laser pulse characteristics has been studied, the study illustrate that the broadening in the duration of Raman laser pulse whenever the value of output coupler reflectivity at Raman photons ( ) R R increases, the study explains that related to the broadening in the falling time of the pulse. Concerning the pulse energy, the study demonstrates the increase which occurs in the energy of Raman laser pulse with increase of the output coupler reflectivity at Raman photons ( ) R R , the study related that to increase in the photons density. A according that mentioned the study illustrate the increase in the power of Raman laser pulse with the increase of the output coupler reflectivity at Raman photons ( ) R R .Finally, the study arrives to concludes that the passive Q - switching laser system of Nd : YVO4, Cr : YAG, with intracavity Raman medium (BaWO4) crystals which takes into account characterized by compatible performance to obtain high power pulses. So, the Raman media which are distinguished by high spontaneous scattering factor are more efficient to realization high power Raman laser pulses. In addition, the quality factor of resonator is found tobe proportional with the spontaneous scattering factor of Raman medium.

المستخلص: In communication field, there are many advantages for using terahertz carriers in optical data transmission along both analog and digital links such as small antenna sizes and large information bandwidth. The optical injection locking is an alternative technique to improve the dynamic properties of QCL light sources. In this technique the frequency and phase of one laser oscillator, known as the slave laser, are locked through the direct coupling to the light injection from another laser oscillator, known as the master laser. In this work, the optical injection locking induced laser dynamics in a QCL is investigated theoretically. The present theoretical analyses are based on the rate equations model that takes into account all carrier relaxation processes as well as the effect of the optical injection locking. The small signal analysis is used to calculate the intensity modulation response and intensity noise in QCL. The present analysis focuses on the effect of carrier relaxation time and the optical injection locking on the dynamic properties in these devices. The results show that the optical injection locking and fast carrier relaxation time can enhance the dynamic properties and decreases noise value and increases the modulation bandwidth in these advanced lasers. The optical injection locking increases the carrier density in active region to suppress the effect of fast carrier scattering to lower state and enhances the stimulated emission. The fast carrier relaxation times decreases the threshold injection current. Also, in optical injection operation, the active region length and linewidth enhancement factor has strong effect on the intensity modulation response and intensity noise.

المستخلص: The present work is a theoretical study for the electronic properties of the electron transport process throughout some molecular structures. The investigated system is a left lead - donor - molecule - acceptor - right lead. The investigate molecule is one of the following structures (Phenyl, Biphenyl, Triphenyl, Naphthalene, Anthracene and Phenanthrene).A theoretical treatment of steady - state has been presented to express the transmission probability of the electron transport throughout ring structures. The Hamiltonian describing the system is the Anderson - Newns Hamiltonian with neglecting the spin and Coulomb interactions on the system. The treatment easily includes a magnetic flux effect on the transport process for any ring structure. Furthermore, the most important effects, taking into consideration, are quantum interference, gate voltage and bias voltage. The transmission probability is employed to calculate the conductance and electric current.Density functional theory (DFT) has also been used to calculate electronic properties of considered molecules, especially on the energy - band gap and density of states, and the distribution of electronic density (HOMO and LUMO). It has been ensured that all studied systems simulated using Caussian program 09 can be fabricated by utilizing their computed total energy.The quantum interference effect at typical values of magnetic flux was utilized to design quantum logic gates (XNOR gate and NAND gate) and nanoscale rectifier (half - wave rectifier and full - wave rectifier).

المستخلص: The superconvergence of finite element solutions is surely an interesting and useful phenomenon in scientific computing of real world problems. The main objective of this thesis of is to construct a new approximation by post - processing an existing finite element solution so that the new approximation is closer to the exact solution than the existing finite element solution. The accuracy of finite element approximation can be improved to obtain superconvergence by applying some post process techniques to them. The - projection method is a such technique. The idea of the method is to make an - projection of existing finite element solutions to another finite element space associated with a coarse mesh. The advantage of this method is that it is easy to implement and can be applied to different elements with general meshes. We will apply the - projection method to obtain the super convergence for the different finite element approximations of the second order elliptic problem. The finite element methods involved are the conforming finite element method and the nonconforming finite method for the second order elliptic problem.

المستخلص: The Qur'an is a source and main source of many studies, The Koran is a source and a basic source of many studies, and whenever the theories are found in the Qur'an, it is not considered a fertile material, since no matter how old the Koran is, the researcher must prepare a strong drink to reach it to safety. The Koran frightens the student and makes him more reluctant to issue Judgments, and impose a lot of caution on him. The Qur'an has transmitted to us the other thought, its dialogues, its arguments, the violation of the rivalry, and the stubbornness of the infidels, the polytheists, the apostates, the misinformation and the falsehoods. This is what needs to be highlighted for its widespread popularity in our present age. In the Holy Quran, a study in the light of the theories of the pilgrims. This is a discussion of the spoken words about the human beings in the Holy Quran, and the research is not subject to the words of Allaah or the Prophets (peace be upon them), because it is identical to reality and does not involve deceit or deceit.The premise of the study is to search for the concept of disinformation and how it was employed by the misguided in the Holy Quran, and study the sophistries, mechanisms, methods and methods employed in the verses of disinformation.The research is based on three chapters, preceded by a preface and followed by a conclusion. In the introduction, we address the conceptualization of misleading language and terminology, its roots and the beginning of its inception in the West and the Arabs, and sophistication. The first chapter dealt with the discourse of the polytheists and the believers. The third topic was devoted to the study of the speech of the people of the book. In the fourth section I studied the discourse of the hypocrites. The second chapter was entitled (The mechanisms of the pilgrims and ways of their work in speech distortion). It divided it into three topics. The first topic dealt with the linguistic mechanisms and their role in deception; the second dealt with rhetorical mechanisms and their role in misleading.The third chapter is entitled (Speech Impulse : Its Methods and Methods). The first two sections studied the methods of disinformation, and the second, methods of disinformation.

المستخلص: Ibrahim Satyrs stories study in structure and significance The short story is an art that combines all the arts in it, from the poem its structure and coherence , the novel with its events and characters , the drama with its dialogue and precision in utterance and language, and articles with its logical narrative and precision. Where it takes from each arts its best and accuracy, to give us artistic enjoyment that locates the short story in line with the writing arts which has been flourished in the last centuries.Many Critics urges that the short story is the best expression of the epoch, for it is an artistic means to reformulate the reality intensively , its fancy and creation enable it to enhance the respondent taste and emotion. With its reality, the respondent recognizes its characters and feels their life details.The study, The narrative Structure in Ibraheem Sabity stories, tackles Ibraheem sabity stories, the organizational model the study follows is that of Gerard Genettee, details in his book , ( Narrative Discourse, An Essay in Method ) with its theoretical statements and procedural tools, and the some ideas of Said Yakeet , in his book ( Analysis of Novelistic Discourse), besides the amendments he has devised on the Genettee structural bifurcations and his Textual transcripts, accordingly the approach is analytical descriptive , of structural theoretical background. The main difficulty encounters the study is that there is no a unified terminological apparatus that systemizes the work of those dealing with narrative, where there are multiple significances for one term as many as the attitude of discourses analysis and its fields. This plurality leads to blurring of the critical vision of most of studies specialized in narrative .Reading Ibrahem Sabty stories according to study approach in narrative techniques raises many legitimate questions, the researcher endeavors to find answer to them : The first question : what are the mechanism of the narrative structure the writer uses in constructing his story texts ? what are their effectiveness in producing distinguish narrative text? Does the writer able to follow hetero - trajectory in using these modern mechanism to achieve singularity?The Second Question : how does the writer able to use the temporal narrative techniques in managing in temporal duration treated in his stories, and does the temporal structure of the stories works only to construct its internal structure or rather go far to take part in creating the sense.The third Question : is it possible to talk on stories of place features, as the titles of the stories suggest? Or is it only artistic means of the writer to direct his readers to what he wants from them?The study is of introduction , three chapters and conclusion. The introduction is of three sections : the first : the genre structure and the text structure, the second : the developments of Iraqi story, and the third : brief on the writer Ibraheen Saby.The first chapter , the narrative temporal, is of three sections. The first : deals with the element of temporal structure by the mechanism of remember and foresight .The second : the temporal sequences deals with the accelerate and slow down narrative. And the third section deals with the narrative frequency through the repetitive tale and frequent tale.The second chapter, the narrative space, is of three sections. The first deals with the space structure and its relation with narrative elements (author, character ,event), the second deals with space and its significances ( political, cultural, social significances ). The third section deals with the construction of narrative atmosphere ( space and temporal ) through the engineering of writing and page.The third chapter, the story event, is of introduction and three sections.The introduction is on the important of event as a core feature due to its relation with other elements of narrative . The first section on the vent inception : the tale inception, the descriptive inception, scene inception, and the dialogic inception. The second section deals with the construction of the event : the sequence construction, the intersection construction. The parallel construction, and the cycle construction. The third section , the epilogue, deals with informative epilogue, descriptive epilogue, briefing epilogue, and dialogic epilogue.The study ends with research conclusions , references , and the story writer books.

المستخلص: This thesis studies stylistic dominations in the Iraqi poet Muthefer Abdulmajed Al - Nauab's poetry. it depends on statistical method to obtain information that helps in analyzing poems according to the descriptive method. It begins with an introduction followed by three chapters; each chapter is divided into two parts as well as the introduction.The first part of the introduction discussed the stylistic study briefly; defining the style, itemizing its kinds and defining each kind to form a basic idea for the reader about this method of criticism. It also explains the meaning of the term "Dominations" in accordance to the critics. The second part discussed Muthefer Al - Nauab's life and his entire work because of his life's importance and its distinction.Chapter one in its first part illustrates the dominant vocal characteristics in Al - Nauab's poetry and defines the poems that this characteristics dominate and their influence on the meaning of these poems. The second part deals with the segment; gives its definition and its kinds. Additionally it takes samples from Al - Nauab's poems and analyzes them.Under the title of " Morphological Dominations", the first part in the second chapter discussed the nominal and verbal dominations briefly after it explains the states of the nouns and verbs; introducing the statistical surveying which the poems getanalyzed according to its results. The second part deals with the derivational nouns; defining each noun and analyzing the poems with regards to the results of the statistics.The final chapter demonstrates the formational dominations. Its first part deals with "Reference" in syntactical dominations as pronouns, adverbs and demonstrative. Then it studies conjunctions. The second chapter studies the rhetorical styles.The thesis concludes that the vocal, morphological, syntactical and rhetorical dominations have an apparent influences on the poems.

المستخلص: The research deals with the meanings of linguistic construction in the Quranic stories on the levels of phonetic, morphological and syntactic, through which the linguistic miracles of the Holy Qur'an emerged, which is the basic objective that the research sought to achieve.At the vocal level, the sound has a clear effect in highlighting the significance of revelation in the presentation of meaning and its impression on the level of the individual and the linguistic context of the verses of the Qur'anic stories. We see in the places of strength and strength the powerful sounds that characterize these qualities, while in another place, And the mollified in the places of the remembrance of mercy and the divine kindness of his servants.And we see another sound phenomenon close to the construction of the same word according to the balance of one word, which is called the balance of morphology, noting the changes of the semantic change in the construction of the word and its impact in achieving the meanings that are sometimes multiplied by the construction of that word morphological, In the indication according to the context.The research also aims to identify a very important and accurate phenomenon that is manifested in verbal relations that include various structures and tools in achieving a systematic structure in which the Quranic narrator understands theThe Ministry of Higher Education and Scientific Research Dhi Qar University College of Education for Human Sciences The department of Arabic language
