Abstract: تضمنت الدراسة الحالية التاثيرات السمية الحادة والمزمنة لمبيد 2, 4 - d في نوعين من اسماك الكارب (الاعتيادي والعشبي)، استعمل في دراسة التاثيرات الحادة عدة لكلا النوعين قيد الدراسة وكانت ((170, 165, 160, 155, 145, 140, 130 و(140, 130, 115, 95, 70)ملغم/لتر ع | This study included acute and chronic effects of 2, 4 - d pesticide in two species of carp fish (Cyprinus carpio and Ctenopharyngodon idella) using several concentrations for the two carp fish species that were (130, 140, 145, 155, 160, 165, 170) and (70, 95, 115, 130, 140) mg/l respectively for 96 hours, to determine the median lethal concentration (LC50) and the behavioral changes was used as a standard of those effects. Whereas three concentrations (20, 40 and 60) and (10, 15, 25) mg/l respectively for the two carp species were used in the chronic exposure for six weeks. The behavioral, histological and hematological changes were used as a standard to observe these effects through the study period. The value of LC50 for common carp fish were 157.77, 157.25, 156.41 and 152.62 mg/l. For grass carp, LC50 were 115.92, 114.92, 112.94 and 96.52 mg/l for 24, 48, 72, 96 hrs of exposure to 2, 4 - d pesticide concentrations respectively.Behavioral changes were recorded more effects in high concentrations than in low concentrations. To discover the toxic effects of this substance on fish, many parameters were used. They included the clinical symptoms by erratic swimming, hyperactivity, loss of equilibrium with respiratory effects such as rapid gill movement and swam near the water surface. While in chronic effects, blood parameters were changed in Red Blood Cell R.B.C., White Blood Cell W.B.C., Packed Cell Volume P.C.V., Haemoglobin Hb and liver enzyme (GPT & GOT).Values elevated significantly according to the pesticide concentration (P?0.001) and exposure periods (P?0.05) in comparison with control. The histological examination of the gills, liver and kidney of the common and grass carp fish after chronic exposure to 2, 4 - d herbicide showed pathological changes and alterations such as fusion of the secondary lamella, epithelial lifting, blood congestion, epithelial hypertrophy of the lamellar epithelium and epithelial necrosis. In the liver, pathological changes were seen, including hepatocytes hypertrophy, cytoplasmic vacuolation, blood congestion and cellular necrosis. Degenerative changes of the renal epithelium, necrosis in renal tubules and occlusion of the tubular lumen where the pathological alterations in the kidney.

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

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

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

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

Correlation and regression coefficient were also used to evaluate the relationships between studied parameters and time. Vegetative growth parameters that are measured were : plant leaf number ; stem height; stem diameter; plant leaf area; leaf fresh and dry weight; stem dry weight; plant shoot fresh and dry weight. Flowering parameters were : curd fresh and dry weight and curd diameter. The results could be summarized as following : 1. Water chemical analysis showed that irrigation with magnetized treated water had an effect on physical properties, nevertheless, was more or less affected ions components. 2. The use of magnetized treated water in irrigation resulted in an increase in germination percentage of cauliflower seeds cv. Solid snow.The highest germination percentage was obtained from magnetic intensity of 1500 Gauss in both experiments, laboratory and field that reached 71.14 and 65, 62%, respectively on the base of Arc Sin. 3. The use of magnetized treated water in plant irrigation at all the used intensities resulted in an early emerged curd cauliflower by 15 days compared with control treatment plants. 4. 750 gauss magnetized treated water achieved at age of 138 days from transplanting, the highest plant leaf area mean is (4836.2 cm2) with percentage increase of 51.7% compared to control treatment plant leaf area (3188.3 cm2).That effect was reflected on curd weight. 5. 1500 and 2500 Gauss magnetized treated water treatments at earlier ages increased the values of vegetative growth parameters which reflected its effect on flowering growth parameters by shorter time of curd irritation, compared with the effect of 500 - 750 Gauss at earlier ages , which are in spite of its late effects produced at 150 days old from transplanting particularly 750 Gauss the highest mean of curd fresh weight. 6. 750 Gauss magnetized treated water achieved the highest yield reached 22.2 ton/h. which differed from that productivity gained from control treatment plant(9 - 29 ton/h.) with percentage increase of 138.8%. 7. Organic plant manure addition at both quantities(2.5 and 5.0kg/furrow) resulted in an increase in both vegetative and flowering growth parameters compared with untreated plants. 5 kg/furrow treatment produced the highest means compared to control treatment particularly at the age of 138 days in all vegetative growth parameters. 8. The addition of 5 kg/furrow at age of 150 days produced the largest curd fresh weight 918.4 g. and diameter of 17.2 cm which statistically differed to compared plant treatment that produced 506.0 g. and 13.3 cm. for curd fresh weight and diameter at the same age respectively. 9. 5 kg/furrow organic manure addition resulted in a highest productivity of 21.6 ton/h. compared to that of control treatment of 11.9 ton/h. with an increase of 81.5%. 10. Interaction between irrigation water magnetically treated with 750 Gauss and addition of (organic manure with 5 kg/furrow) at the age of150 days resulted in the highest curd fresh weight of 1292.9 g. with curd diameter of 20.3 cm. compared to that plant of control treatment produced curd fresh weight of 292.5 g. and 11.0 cm. diameter. This interaction also produced 30.3 ton/h. for (750 Gauss×5 kg/furrow) compared with the productivity of control treatment plants that gave 6.86 ton/h. with percentage increase of 341.6%

Abstract: المقوسات الكونديه من الطفيليات الشديده النجاح في انشاء اصابة مزمنه طويلة الامد. وقد اجريت الدراسة الحاليه على 366 امراة (117 مجهضات، 141 حوامل، 108 غير متزوجات) جمعت من مستشفيات مختلفة في بغداد. جمعت عينات الدم لجميع المجاميع المدروسة خلال الفترة مابين تش | Toxoplasma is a highly invasive parasite which establishes a life - long chronic infection. The present study was performed on 366 women (117 miscarriages, 141 pregnant and 108 singles) aged (17 - 35) years old from different hospital in Baghdad. Blood samples were collected from all patients during the period of Oct.2013 until of Jan. 2014. Anti - toxoplasma antibodies in the sera of all samples by using two tests, Latex test (LAT) and ELISA (IgG), (IgM) while, the proinflammatory cytokine were estimated by evaluation of the cytokine such as (IL - 6, IL - 8, TNF - ?). The results were showed that : ? The infection rate of toxoplasmosis by LAT was (41.53%) which was more sensitive than ELISA IgG (36.85%), and miscarried women were diagnosed by higher anti - toxoplasma IgG antibodies 62/117(52.99%), while pregnant result were lower 30/108 (27.78%). ? The most frequent age group of chronic infection with T.gondii was (23 - 28) year in both miscarriage and pregnant women, and represented by 45.16%, 40% respectively. While the most frequent age group for a single woman was (17 - 22) years, and represent 46.511% of the total number of this group.? Seroprevalence of toxoplasmosis by ELISA IgM test revealed low sensitivity in different studied groups 25/366(6.830%), and miscarried women were diagnosed by a highly significant (P ?0.01) percentage of acute toxoplasmosis14/117(11.965%).and The age group of (17 - 22) years old diagnosed high significant (p?0.01) percentage of acute toxoplasmosis in all studied groups.? According to the distribution of infected miscarried women with toxoplasmosis and gestational age by ELISA IgM the result showed that most of miscarriages were occurred at the first trimester which considered high significant (p? 0.01) 8/14(57.42%). While, chronic infected women at the second trimester (4 - 7 month) diagnosed by significantly (P?0.01) higher percentage of miscarried 24/62(38.71%).? The level of pro - infalmmatory cytokine (IL - 6) in acute infected miscarried women with toxoplasmosis distincted with a significantly high increase (P? 0.05) (177.31±12.53 Pg/ml) in comparison to chronic infected one (119.36 ±14.07 Pg/ml).While, chronic infected pregnant women was low significantly (P ?0.01) (48.41± 2.79 Pg/ml) in comparison to acute infected one and other studied groups, ? The acute infected singles was (118.98± 15.68 Pg/ml) higher non - significantly (P?0.05) than chronic infected one (112.65 ± 17.91 Pg/ml) and both disease activity were significantly higher than its level in healthy singles.? The level of TNF - ? in acute infected miscarried women distincted with significantly higher (P?0.05) (97.46 ± 5.37 Pg/ml) in comparison to chronic infected women (69.55 ± 4.58 Pg/ml), Whereas the mean level of TNF - ? in pregnant infected women during acute phase (62.31 ± 3.82 Pg/ml) was significantly (P?0.05) higher than chronic infection (21.42 ±2.74 Pg/ml)? Single infected women showed high significant increase (P?0.05) of TNF - ? level (50.48 ± 7.42 Pg/ml) in comparison to chronic infected one (35.46± 5.36 Pg/ml) and both disease activity scored high significant increase (P?0.05) of TNF - ? in comparison to healthy singles (18.29 ± 1.02 Pg/ml).? Finally, the mean level of IL - 8 in miscarried women with positive infection with T. gondii during acute phase (187.92 ± 15.38 Pg/ml) was significantly (P?0.05) higher than chronic phase of infection (140.57 ± 13.87 Pg/ml).Whereas the mean level of IL - 8 in acute infected pregnant women (110.32 ± 9.13 Pg/ml) was higher significantly (P?0.05) than healthy pregnant (91.49 ± 7.59 Pg/ml) and healthy singles (88.82 ± 5.62 Pg/ml).? Infected single women showed highly significant (P?0.01) increased levels in both diseases activity in comparison to single women without infection (88.82± 5.62 Pg/ml).
