Abstract: تطرقت هذه الدراسة الى معرفة تاثير الدقائق النانوية للفضة (Ag NPs) في بعض الجوانب التركيبية والوظيفية للجهاز التناسلي الذكري للفئران. جرعت الحيوانات فمويا بالـ Ag NPs بجرعة 5 ملغم/مل وللمدد 5, 10, 15 يوما وفي اليوم التالي لانتهاء كل مدة معاملة تمت التضحية | This study touched to know the effect of silver nanoparticles (Ag NPs) on some organs of the reproductive system and the testosterone hormone in male albino mice. animals were orally dosed with 200 mg/kg of Ag NPs for 5, 10, 15 days and the next day to the end of each period of treatment has animal sacrificed and autopsy after taking their weights before and after the treatment for the comparison between them and then took the testes and epididymis (head and tail) from them after measuring their weights. This study included the study of changes in the weight of animals and organs, sperm characters in both the testes and epididymis, the percentage of cells generating sperm, the number of Leydig cells and the diameters of these cell nuclei, changes in the seminiferous tubules in the testes and changes in epididymis tubule and histopathological changes as well as changes in testosterone level. The results of the animals weights before treatment showed a significant decrease (P<0.05) compared to the weights of the same animals after treatment, while the results of this study after comparing with the control group showed a significant decrease (P<0.05) in the weights of testes and tunica albuginea for the periods of 5, 10 and 15 days. The epididymis showed a significant decrease (P<0.05) in the average weights of the epididymis head for the three periods while the average weights of the epididymis tail showed a significant decrease (P<0.05) for the periods of 10 and 15 days. The vitality and the concentration of the sperms showed a significant decrease (P<0.05) in their percentages for the three periods. All the results above showed a significant decrease (P<0.05) when they compared between the three periods of the treatment. While the sperm abnormalities showed a significant increase (P<0.05) in their percentage in each of the testes and epidydimes for the periods 5, 10, 15 days with a significant increase (P<0.05) in these abnormalities when they compared between the three periods of the treatment. The histological results of this study after comparing to the control group revealed histopathological changes in the testes and the epididymis (head and tail). The percentage of spermatogenesis showed a significant decrease (P<0.05) in the number of spermatogonia, primary spermatocyte and sperms when compared to the control group with a significant decrease in the number of these cells when compared the three treatment periods with each other. While the number of secondary spermatocyte and spermatids was significantly increased (P<0.05) when compared with the control, with a significant increase in the number of these cells when comparing the three periods of treatment. Whereas the results of Leydig cells after comparing to the control group showed a significant decrease (P<0.05) in the number and the diameter of the cell nucleus. The results of this study also showed a significant decrease (P<0.05) in the thickness and the diameter of the seminiferous tubules of the testes and the thickness, The epithelium height of the epididymis (head and tail) when compared to the control group with significantly decrease in the thickness and diameter of the seminiferous tubules of the testes and the thickness and epithelium height of the epididymis (head and tail) when they compared between the three treatment periods. The results of this study when compared to the control group showed a significant decrease (P<0.05) in the level of the testosterone hormone with significantly increase (P<0.05) in the testosterone level when compared between the periods of 5, 10, 15 days. From these findings it is concluded that the AgNps crossed the blood - testis barrier and caused many changes to the testicular tissues and decreased the level of the testosterone. This may affect the fertility of mice.

Abstract: ان الاثار البيئية لزراعة الاسماك في اقفاص التربية في العراق لم تتم دراستها بصورة جيدة،علما ان هذا النشاط يمارس على نحو متزايد وهناك حاجة كبيرة لدراسة الاثار المترتبة على ذلك.اجريت الدراسة الحالية على مواقع اقفاص تربية الاسماك في نهر دجلة شمال بغداد للتعر | The present study took place on fish farming cages located in the Tigris River in the north Baghdad, to in order to study the effects of high fish densities on zooplankton communies in addition to study of some physical and chemical factors.The environmental effects of fish farming in cages in Iraq have not been studied well, knowing that this activity is practiced increasingly and there was a significant need to study the implications of this important mater.The aim of this study was to investigate the effects of carpfish farming cages on the density of zooplankton in the Tigris River, The samples were taken twiece a month form the three stations for six months from January to June 2014 in three selected stations in the river stream : the first place was Al - Rashidiya station which located in Al - Rashidiya area (Kadhim Al - Ali), 5 km from tourist Baghdad island and the second station was Algriaat 1 which located in Algriaat area in Rusafa side of Baghdad city corresponding to the Kadhimiya near the bridge of riverain pedestrian (Al - Duab bridge) connecting between Al - Rashidiya, while the Al - Kadhimiya and the third station was Algriaat 2 which located in Algria’at zone corresponding to the area of Kadhimiya.The study included the identification studying the density of three grops of zooplankton which were Calanoida, Cyclopoida and Cladocera in addition to the measurement of some physical and chemical characteristics of river water and its effect on the three zooplankton community according to their importance, which included velocity of water current, water temperature electrical Conductivity and Salinity, pH, dissolved oxygen(DO), biological oxygen demand (BOD), phosphate concentration and nitrate concentration. The results of the present study showed that the density of Cladocera. Was lower than the densities of Calanoida & Cyclopida in the three station. on the other hand the current study showed that the densities of both Calanoida and Cyclopoida were oscillatory during the months of th study between highest and lowest, without in statistically significant differences, but the highest densities in June, and this study shows that the highest densities of the three groups of zooplankton were recorded in June. The present study showed a negative effect of the high density of the fish in the cages on the density rate of planktonic crustacea by reducing the numbers and the density of planktonic crustacea community inside cages. Compared with planktonic crustacea community outside the cages and with those within 100 meters far from cages, the differences were statisticaly singnficance.On the other hand regarding to the results of the physical and chemical factors it was found a highest that the velocity of water current rate was 82.50 cm/s in Algria’at 2, while the lowest was 43.33 cm/s in Al - Rashidiya station.Water temperatures ranged between 9C° in Algria’at 2 to 32C° in Al - Rashidiya station during the study period.The highest rate of electrical conductivity was 1032.00 ?S/cm in Algria’at 1, while the lowest was 765.25 ?S/cm in Al - Rashidiya station, while the highest rate of the salinity concentration in the fish cages was 0.66 mg/L in Algria’at 1 and the lowest concentration of salinity was in Al - Rashidiya 0.48 mg/L.pH values ranged between 7.20 in Algria’at 2 to 8.05 in Algria’at 1 in March for both stations, whil the concentration of dissolved Oxygen in water concentration ranged between 5.95 mg/l in Al - Rashidiya to 7.70 in Al - Rashidiya and Algriaat 1. and the Biological Oxygen Demand ranged was between 4.11 mg/l in Algriaat 1 to 6.50 mg/L in Al - Rashidiya station during February for both stations. It was also found that the lowest concentration of phosphate was 0.016 ml/l in Algriaat 2 in april while the highest concentration was 0.075 mg/l algreaat2 in march Also it was found that the lowest cocentration of nitrate 0.82 mg/l was recorded in al griaat 2 in fabruart while the highest conceneation 1.90 mg/l was recorded in Al Rashidya in june.All the results of the physical and chemical factors founded were within normal allowable environmentally boundaries and which have no effect on the aquatic planktonic crustacea community.

The results of morphological cultures and microscopic study, biochemical tests, In addition to the use of diagnostic system Histrep and then the final diagnosis by a Vitek 2. Molecular diagnosis showed that all isolates contained 16S rRNA gene. Susceptibility test was done for all bacterial isolates against (9) antibiotics. The results showed that all isolates were complete resistance (100%) against Erythromycin, Tetracycline, Rifampin and Ciprofloxacin. While its resistance for other antibiotics was varied. The resistance isolates for Chloramphenicol, Nitrofurantoin, Penicillin, Gentamycin and Vancomycin were 50 %, 85%, 60 %, 70 % and 35 %, respectively. The results showed that the total resistance for E.faecalis isolates was higher than the sensitivity (more than 70% of these antibiotics). Polymerase chain reaction was used for detecting some genes for antibiotics resistance. The results showed that 7 bacterial isolates had van gene which were resistance to Vancomycin. 6 isolates of these bacteria contained vanB gene while one isolate contained vanA gene. Also the results showed that the bacterial isolates had antibiotics resistance genes as follow : aac (6) - aph (2) gene responsible for resistance to Gentamycin, cat gene responsible for resistance to Chloramphenicol, erm (A)gene responsible for resistance to Erythromycin, and tet (M) gene responsible for resistance to Tetracycline were 70%, 50%, 45%, 100% respectively. Some virulence factors had been detected for bacterial isolates including the ability of isolates of haemolysin production, protease production, gelatinase production and the ability to capsule formation. The results showed that 5 isolates (25 %) its ability of producing was type beta, and 15 isolates(75%) its ability of producing protease, 8 (40%) its ability of producing the gelatinase , and 5 isolates (25%) had the ability on capsule formation. The investigation for these virulence factors in genotypic method, the results showed that bacterial isolates had cylA gene responsible for the production of haemolysin, asal gene responsible for the production of aggregation substance, esp gene responsible for the production of Surface proteins for Enterococcus faecalis and hyl gene responsible for the production of hyaluronidase the percentage 25%, 90%, 55% and 5% respectively.

Abstract: The aim of This study is to determine the prevalence of OXA ? - lactamase in pseudomonas aeruginosa isolates from clinical and other environmental cases in Al - Diwaniya Teaching Hospital using phenotypic and molecular methods.The Samples of the study were collected from various sources and they were 390 samples for the period from November 2011 to March 2012, and they includ (292 clinical specimens and 98 environmental sample), the results of cultural and biochemical tests showed that 50 isolates (39 of them were from clinical cases and 11 were from environmental samples), belonged to ps. aeruginosa, and their diagnosis were confirmed by 16s - ribosomal RNA, and the study showed that all the isolates containing the 16s - ribosomal RNA gene, which represents the designed diagnostic gene in this study.The results of this study showed that the higher rate of P. aeruginosa isolates was due to burns infections (23.68 %) , followed by respiratory tract infections (sputum) that were (15.38 %) and then the case to otitis media infections (12.5 %), and lastly that due to urinary tract infections (10.49 %), while the rate isolation from the environmental samples was (5.11 %) from the floor of burns department, followed by (10.8 %) from the medical instruments of department workers.It was noted from this study that the age and gender of the patients have some effect on the infection by P. aeruginosa it was recorded that the higher rate of infection was in patients older then 61 year old, and regarding gender, it was found that females are more infected than male, especially in urinary tract infections. The study showed that there is high rate of infection in the admitted patients, in older people and in those who need urinary catheterization, in addition to those with severe burns and those in the intensive care units. Drug sensitivity test had been carried out for all the bacterial isolates to 22 types of antibiotics by disk diffusion method of Kirby - Bauer, and this study had indicated that there was relatively high resistance from P. aeruginosa to ? - lactam antibiotics, aminoglycoseides, and fluoroquinolone. The results also showed that the studied isolates has possibility of producing broad - spectrum ? - lactames enzymes, and this is supported by the resistance of this bacteria to the third generation cephalosporins and to Alaztronam, it was also shown that there was difference in the resistance to carbapenems antibiotics, the resistance rate to imipenem and meropenem were 16% and 64 %, respectively. Polymyxin B and Polymyxin E also called (Colistin) antibiotics were also used, and the resistance rate %0 for Colistin and %4 for Polymyxin B, that means there was two isolates which are resistant to Polymyxin B and this resistance was a challenge to the success of therapeutic efforts. this study noted that there was 22 (44%) isolates which were resistant to at least three types of antibiotics, and regarded as multi - drug resistant (MDR) and Extensive - drug resistance (XDR) isolates were26 (52%) which was the higher rate among the three types of resistance, The third type of resistance was 2 (4%) which represents the resistance to all types of studied antibiotics (PDR). The ability of these isolates to produce broad - spectrum OXA ? - lactames enzymes groups was investigated thrrough detection of presence of genes blaOXA - 10, blaLCR - 1, blaOXA - 18, blaOXA - 1, blaOXA - 2 in these isolates by using the polymerization chain reaction enzyme technology] (PCR) it showed 50/50 (100%) isolates contain blaOXA - 10 gene, which belongs to the OXA group I, and the results of this study showed no amplification results for blaOXA - 18, blaLCR - 1, blaOXA - 1, blaOXA - 2 genes, which belong to the main groups of broadspectrum OXA ? - lactames enzymes which are OXAgroup II, OXAgroup III and OXA groupV respectively except OXA18 enzyme

Maize seed of varieties Broujen and Cadiz were planted in dates 15/ 1, 15/ 2 and 15/ 3 in Polyethylene bags 8 cm diameter and 18 cm depth in the greenhouse. Seedlings were transferred on 15/1 and 15/2 to the field in 15/3. While the varieties of maize planted inside a greenhouse in 15/ 3 when plants were 4 to 5 leaves transferred to the permanent field. It was in 5 / 4, after 21 days from planting. The experiment was applied according to the Split Plots Design with three replications. Each replicate was divided into two main plots (Broujen and Cadiz variety). Each main plot was divided into four secondary plots which were treatments of methods of agriculture (method of transplanting technique in the greenhouse which is seedlings 15/1, seedlings 15/2, seedlings 15/3 and traditional agriculture method in the permanent field in 15/3). Results have shown that seedlings dates 15/1 and 15/2 led to the events of a significant increase in the mean of plant height, number of leaves, leaf area and leaf area index. they reduce in the vegetative growth period and increase in the weight and length of ear, the number of fertilized grain in it, grain yield, biological yield, harvest index and percentage of oil. Varieties showed significant effects on the growth and yield characters. Broujen variety has achieved increase in mean of plant height, stem diameter and reduce in the vegetative growth period and increase in the biological yield. The interaction between the methods of agriculture (method of transplanting technique and traditional agriculture method) and varieties have shown significant effect in stem diameter (before flowering and at the maturity), green leaves number, dead leaves number, leaf area, leaf area index, vegetative growth period and flowering growth period. Therefore, The interaction between the methods of agriculture and varieties have shown significant effect in ear weight, grain weight, cob weight, fertilized grain number, aborted grain number, biological yield, grain yield, harvest index and percentage of oil and protein.

Abstract: تعد ديدان قليلة الاهلاب المائية مجموعة حيوانية تضم انواعا مهمة من الناحية الاقتصادية والعلمية كونها غذاء جيدا للاسماك، ودورها في النظام البيئي بوصفها مؤشرات حياتية معروفة في تقييم نوعية المياه ودرجة تلوثها. وبسبب قلة الدراسات التشخيصية وعدم وجود قائمة خ | Aquatic oligochaete worms is an animal group that contains important species, economically speaking as its being a good fish food, and its scientific role in the ecosystem as well known bio - indicator for assessment water quality and evaluate the degree of water pollution. Due to little identification studies available about this group, and the absence of Iraqi checklist of species, the idea of the current study came, which concerned with the community of aquatic oligochaetes worms in the middle sector of the Euphrates River. Three sites have been chosen for this purpose, the first site is on the Euphrates River in the district of River at Al - Mussayab city (S1) and two streams branched from it, including Al - Mashroo'a stream (S2) and Abu - alasafeer stream (S3).These sites are characterized by sediment texture ranged from silt - sandy sediment in S1, sandy in S2 and Sandy - Clay in S3, the percentage of organic matter in the sediment ranged between1.8 - 2.6 % in S1, 0.7 - 1.9% in S2, and 4.8 - 6.4 % in S3. As far as plants concern, the presence of reed plant Phragmites australis, Potamgeton crispus plant, Hydrilla verticellata plant, and some filamentous algae in all study sites.Total of 1720 individuals of aquatic oligochaeta have been sorted out during the study period from all sites representing 37 species belong to the family Lumbricidae, Tubificoid naidid worms, Naidid worms of subfamily Naidinae and subfamily Pristininae, and finally, family Aeolosomatidae. Eleven species were considered as new records for Iraq. Regarding study sites, S2 recorded a least number of individuals and number of species, while the number of individuals and number of species were converged at S1 and S3. Results of the Species Richness Index showed that the highest value was recorded at the S3 and reached 8.37, while Species Uniformity Index, ranged between the highest value of 1.88 at the S3 and lowest value of 1.60 in S2, and finally in S1 it was 0.85. Shannon - Weiner diversity Index, recorded its highest value of 6.33 bits / individual in the S3, and lowest value has in of 2.78bits/individual in S1, but it was 4.80 bit / individual in S2. The Results of Jacquard Presence - Community values of similarity showed that the highest degree of similarity is (58.62%) recorded betwen S1 and S2. One species of family Lumbricidae was recorded that is Eiseniella tetraedra in S2.This family recorded a percentage of 3% of the total isolated worms. Total of 584 individuals of Tubificoid naidid worms were sorted with a percentage 34% of the total number of worms and they were identify as nine species included Limnodrilus hoffmeisteri, L. profundicola, L.claparedeanus, Tubifex tubifex, Aulodrilus pigueti, Peloescolex tenuis, Potamothrix hammoniensi, Rhyacodrilus coccineus, and finally Branchiura sowerbyi which recorded the highest percentage of 65.24% of the total tubificoid naidid worms with the highest frequency of 100%, followed by L. hoffmeisteri with a percentage of 16.95% and the frequency percentage of 85.19%, while the remaining species recorded close proportions ranged between 1 - 2%. Peloscolex tenuis was considered as a new record for Iraq, where10 individuals of this species were sorted with a percentage of 1.71%, and a frequency percentage of 3.70 %.Total of 47 individuals of subfamily Pristininae, were sorted, represented five species, including two species of genus Pristinella, P obsorni, and P. sima, and three species of genus Pristina, identified as, P. longiseta, P. aequiseta, and P. foreli, with a highest percentage of 53.19%, and a highest frequency of 14.81% were recorded by P. longiseta. A total of 788 individuals of subfamily Naidinae were sorted represent 20 specie includes Chaetogaster diastrophus, Stephensoniana trivandrana Paranais litoralis, P.frici, Ophidonais serpentina, Slavina appendiculata, S.isochaeta, Specaria josinae, Stylaria lacustris S. fossularis, Dero(Dero) evelinae, D.(D.) nivea, D. (Aulophorus) furcatus, Nais simplex, N.pseudobtusa, N. stolci, N. variabilis, N. elinguis, N. pardalis, Allonais inaequalis. Nine species of which were recorded for the first time in Iraq (in Bold). Species S. lacustris recorded the highest frequency percentage of 59.25%, and the highest individuals number 0f 187 was recorded by both S. lacustris and O. serpentine. Finally, 207 individuals of family Aeolosomatidae were identified into two species, Aeolosoma variegate and A. hemprichi. The first species recorded the highest percentage of 82.61% and a frequency percentage of 33.33%, and the second species recorded a percentage of 17.39% and a frequency percentage of 29.64%.

The first tribe : (Cardueae), It included the Species : (Arctium tomentosum, Carlina vulgaris, Chardinia orientales, Cnicus benedictus and Notobasis syriaca). The second tribe : (Lactuceae), It included the Species : (Geropogon glabrum, Geropogon hybridus, Hedypnois cretica, Koelpinia linearis and Urospermum pecroides). The morphological study involved the roots according to the characteristics, the form and dimensions (the length and the diameter), the study of the stem by the character, the color and the indumentums, also the dimension (the high and diameter) it resulted good characteristics, enabled us to use it in isolation of the types. It is also discussed the leaf on the based of the quantifier and qualifier that involved the form of the leaf and the form of the peak and the base, the character of the blade margin and the epidermis. The study also high lighted the dimension of the blade (the length and the width), The morphological characteristics of the leaves have given a great Taxonomical value rather than the root and the stem. It also mentioned in this study the Inflorescences in general : the form and the diameter of the receptacle, the dimension of the inflorescence (length and width), and the characteristics of the phyllaries, the study of Achenes, the length of the beak, the character of the filaments that connected by the peak of the beak. The proper morphological characters of the Inflorescences made the contrastive among the characteristics of the Inflorescence in unique type. This great advantage is useful in the classification of the species. The anatomical study contains the study of the dermal tissue system that belong to the types under study, specially the stem, the leaf. It make clear the differences among the characters of the epidermis cells for the stem and the leaf (the upper and lower epidermises), It tackled the study of the Stomata at the leaf and the stem, and measure of the frequency at these members. It also discussed the fundamental and vascular tissue system of the root, the stem and the leaf through the study of their characteristics of the transversal sector. It is also studied the vascular bundles according to the thickness of the regions belonged to the xylem and phloem; the number of the xylem arms in each bundle and the number of the vascular elements in one xylem arm. The study involves the system of the veins into the leaf blade or that called (Venation), and the thickness of the veins and its course, the behavior of the vein's ends and the method of its contact with the leaf margin. In addition, the study dealt with the method of the joining veins the secondary by the primary and the third veins by the secondary. Thus, the study make clear the considerable advantages that distinguish the types each other. It is observed the characteristics of the leaf's venation is a constant character that depends upon to classify the species. At end of the study, It is used the results of the morphological and anatomical characteristics in comparison of the two tribes; Cardueae and Lactuceae that the studied species followed.

The results of the present study showed that 56% of the subjects were pregnant and 44%were not. The highest percentage of the infected subjects was of 26 - 30 years old as 30.37% among the pregnant women and 36.35% among the non - pregnant women of the age mentioned above. The highest percentage 37.5% of abortion of the first period of pregnancy was in pregnant women, and 45.53% in non - pregnant women. The results of the study also showed more cases of infected women among those who bred animals in their living places as 69%. It is also found that the highest percentage of the infected women 64% were of those who use the running water for drinking. Moreover, it is noticed that there is an increase in the percentage of the infected women among the uneducated women 38%. The study showed that the percentage of the infection is proportional to residence 63%, the infection increase among women living in rural areas. The percentage of T - lymphocytes in peripheral blood of patients were also measured through measuring the percentage of the CD4+ and CD8+cells by using fluorescent microscope.The results showed a significant decrease (p<0.05) in this type of cells.The rate of percentage of CD4+ of the patient's were 31.704±0.116 while the rate of CD4+ in the peripheral blood of the control group was 62.260±0.237.The rate of percentages of CD8+ 19.382±0.080, whereas it was 31.680±0.307 of the control group.The rates of the percentages of CD4+ to CD8+ were also measured, the results showed a significant decrease (p<0.05) in the rate of the percentage in the patient's group 1.642 while it was 1.968 in the control group. The statistic analysis showed significant differences between these tow groups (p<0.05). The intensity of Zinc and Copper has been measured in the serum of the infected women via use of Atomic absorption instrument, a significant decrease (p <0.05) appeared in the rate of Zinc intensity in the serum on the infected women as compared with the control group.The rate of the intensity in patient's group was 4.65% ± 2.628µmol /l while in the control group it was 15.353± 1.640 µmol /l.A significant increase (p<0.05)was also noticed in the intensity of Copper in the patient's group (28.589±4.335 µmol /l)whereas it was 12.854±1.501 µmol /l in the control group. The index of the specific antibodies IgM and IgG related to Toxoplasma gondii was measured by ELISA method, a significant increase (p<0.05) was observed in the value of IgM and IgG in the patient's group as compared with the control group. The rate of index for IgM in the patient's group was 1.354±0.05 while it was 0.163±0.05 in the control group. The rate of value of IgG in the patient's group was 1.163±0.074 whereas it was 0.358±0.033 in the control group. In the present study, Toxoplasma gondii was isolated and diagnosed from human as first attempt, and then the infection was created in laboratory mice as an essential step for growing the parasite. The second step was studying the effect of some selected drugs on the experimental treatment for disease of toxoplasmosis created in the mice. The drugs are : Pyrimethamin, Clarithromycin, Spiramycin, Ivermectin.The results of the study showed the effects of these drugs on the tissue cyst formed in the brain and lungs. The number of tissue cysts in the brain of the mouse treated with pyrimethamin was 14.8 ±1.067 after 28 days. Significant differences appeared when this result compared with the control group in which it was 27.4±1.029. The number of tissue cysts formed in lung, tissue in the mouse treated with the same drug after the same period of the time was 6.2±0.583.This showed a significant differences as compared with the control group in which it was 10.2±0.583. No significant differences appeared between both groups as for the treatment by Clarithromycin antibiotic as far as the number of the tissue cysts formed in the brain after 28 days is concerned. The number was 23.8 ±0.86 as compared with the control group 38.6±1.029.The same compared is true of the lungs, tissue. The number of the tissue cysts was 23.8±0.86 as compared with the control group 28.4±1.805. Concerning the antibiotic Spiramycin, the results showed the effectiveness of it in decreasing the tissue cysts formed in the brain.The significant differences were (p<0.05), the rate of the cysts was 9.6±0.6 as compared with the control group in which it was 22.8±1.067.The same effectiveness appeared on the lungs, tissue as the rate of tissue cysts after 28 days of treatment was 4.6±0.509 as compared with the control group in which was 17±1.14 and the significant differences were (p=0.000).The Ivermectin drug showed a great effectiveness in minimizing the number of the tissue cysts formed in the brain and the lungs. The numbers of the tissue cysts formed after 28 days were 3.2±0.374 and 1±0.316 respectively; significant differences are observed when these numbers are compared with the numbers of the control group which were 22±1.843 and 19.4±1.435. Thus, the use of Ivermectin drug is considered as a pioneer and fruitful study since this drug has not been used for the treatment of Toxoplasmosis.

Abstract: يتميز سن الياس (Menopause) لدى الاناث بتوقف الحيض وتصبح الانثى غير خصبة بسبب فقدان جميع الحويصلات المبيضية (Ovarian follicles) والانخفاض الشديد لهرموني الاستروجين والبروجسترون صممت الدراسة الحالية لفحص الاضطرابات الفسلجية المختلفة والتي تشمل بعض المعايير | Menopause marks the time in women's life when her menstruation stop and she is no longer fertile because of exhaustion of ovarian follicles and sharply decrease in ovarian production of estrogen and progesterone.The present study was designated to determinate different physiological disturbances which occurring in some hematological and biochemical parameters of postmenopausal women. A total number used was 130 women, 100 women were postmenopause and subdivided into four age groups (46 - 50 year, 51 - 55 year, 56 - 60 year, and 61 - 65 year). Thirteen women were premenopause , used as a control group, their ages ranged between 20 - 30 years. In all age groups of postmenopausal women, it have been found that the levels of estradiol hormone were progressioly decreased (p<0.05) when compared with control group. Regarding hematological parameters, RBCs count was insignificantly increase (p>0.05) in all age groups of postmenopausal women. Levels of hemoglobin concentrations and packed cell volume were significantly increased (p<0.05) in all age groups of postmenopausal women compare to control groups. Blood platelets count recorded insignificant fall (p>0.05) in most age groups of postmenopausal women.As for, red blood indices (MCV, MCH, and MCHC) explained insignificant differences (p>0.05) of most menopausal women in a comparison with those control group. Total white blood cells have insignificant elevation (p>0.05) of most groups except 56 - 60 years groups. Regard to differential white blood cells, Levels of lymphocytes and monocyte have been showed insignificant drop (p>0.05) of the level of lymphocytes and significant increase (p<0.05) of first and second age groups in the levels of monocytes of postmenopausal women. Granulocytes white blood cells have been indicated different changes : Nentrophils were significantly higher (p<0.05)in all age groups of postmenopausal women, where as, eosinophils and basophils were insignificantly different (p>0.05) in most age groups. Concerning biochemical changes, Total serum proteins, Albumin, and globulin have been showed significant lowering (p<0.05) in all age groups of postmenopausal women. Statistical analyses showed a significant rise (p<0.05) of serum uric acid and urea levels in most group of postmenopausal women. Measurments of enzyme activities involved in liver (ALT and AST) were significantly hightened (p<0.05) in most age groups of postmenopausal women, Whil, ALP activities recorded insignificant increase (p>0.05) in all age group of postmenopausal women. Determinations of minerals showing a significant increase (p<0.05) in the levels of calcium and insignificant increase (p>0.05) in the levels of phosphorus in all groups of post menopausal women. Analyses of electrolytes have been explained a significant elevation (p<0.05) of the sodium and non significant difference (p>0.05) of the potassium in all groups of postmenopausal women.The present study involved determination specific and essential trace elements, Levels of copper explained a significant decrease (p<0.05) in all age groups associated with a significant increase (p<0.05) of zinc levels in postmenopausal women. Inversly, Values of magnesium were insignificantly different (p>0.05) in all age groups of postmenopausal women. The present study selects specific parameters to explaine oxidative stress in postmenopausal women. Levels of malondeheyds were significantly elevated (p<0.05) in all groups of postmenopausal women, and correlated negatively (r= - 0.102) with level of estrogen. Values of reduced glutathione showed a significant decrease (0.05) in postmenopausal women and correlated positively (r=0.64) with the estrogen hormone. Analyses of antioxidants enzymes have been showed a significant decrease (p<0.05) in the activity of catalase enzymes of all groups of postmenopause. Also, the activity of glutathione peroxidase was significantly decrease (p<0.05) in postmenopausal women and its correlation coefficient was r=0.263. In conclusion, changes summarized above may be attributed to deficiency of estradiol hormone in postmenopausal women which resulting in different physiological disturbances and these changes become aggravated and exacerbated because of oxidative stress occurring in decrease of estradiol hormones.

And we obtained 50 bacterial isolates from 20 samples from contaminated and non - contaminated soils were distributed different areas of Baghdad for a period of 1st May 2013 till 1st August.Number of cultural microscopically, biochemical and sensitivity to antibiotics tests had been, than diagnosis was confirmed by API20E system.These isolates was tested for ability to production of biosurfactants (rhamnolipid) by haemolysis, oil spreasding test, calculate value of emulisification factor (E24) and measuring surface tension for liquid media. Tow isolates (PS42 and PP8) had been selected, first one was from soil samples and other was from pathological samples because of they have highest productivity, haemolysis ability, oil spreading, highest emulisification factor value and highest in lowering surface tension, there for these tow isolates selected for study their inhibitory activity against types of bacteria. The rhamnolipid was extracted from tow isolates P. aeruginosa PP8 and P. aeruginosa PS42 by using mixture of solvents as was obtained 15.45 g and 18.25 g per liter of each of the PP8 and PS42 respectively. The rhamnolipid was diagnosed by thin layer chromatography technology (TLC) and high - performance liquid chromatography (HPLC) showed that tow bacteria produced three types of rhamnolipids (mono - , di - rhamnolipid and rhamnolipid A). The rhamonlipid efficiency was tested for inhibitory activity against bacteria by measuring diameter of inhibitory zone surrounding holes and discs. The inhibitory activity was high against Bacillus cersus bacteria followed by P. aeruginosa, than Staphylococcus aeraus and the lowest one was E. colli. The inhibitory activity for biosurfactant was approached to inhibitory activity for industrial surfactants. Also in this study has been determined minimum inhibitory concentration (MIC) value and Minimum Bactericidal Concentration (MBC) value for biosurfactants and the results varied depending on different types of biosurfactants and type of bacteria and the lowest values for MIC and MBC of biosurfactant produced by P. aeruginosa PS42 on growth of B. cereus and reached to 16.It was first time at local level for testing inhibitory activity of biosurfactant against pathogenic bacteria S. aureus and P. aeruginosa which was studied in vivo (injuried skin) after introduction these pathogens experimentally into laboratory mice with clinical symptoms appeared in injured skin after 48 hours and then treated mice groups with of 30 mg \ ml concentration of biosurfactants produced from isolates of bacterial (P. aeruginosa PP8 and P. aeruginosa PS42), resulted in a decrease in the time required for healing as found from the results obtained by the different length of period needed for healing (depending on the nature of injury and type of microorganism that causes injury).The mice had been recovered after 5 days when used biosurfactant at concentration 30 mg/ml produced P. aeruginosa PS42 followed by mice recovered after 6 days when used biosurfactants 30 mg/ml produced by P. aeruginosa PP8 in comparison with control group which recovered after 12 days for mice infected with S. aureus. In mice infected with P. aeruginosa recovered after 10 days when used biosurfactant produced by P. aeruginosa PS42 at concentration 30mg/ml and followed by mice recovered after 12 days when used biosurfactant produced by P. aeruginosa PP8 at concentration 30mg/ml in comparison with control group which recovered after 17 days.

It also included the preparation and detection of two hybrid nano compounds, one of them from the disinfectant chlorhexidine and the other from the tannic acid. The inhibitory activity of the nano disinfectant was assessed against the isolated bacteria in this study also, the antioxidant activity of the hybrid nano tannic acid was identified and the results showed the following : 1 - As a total 32 samples were taken from burned patients hospitalized in the burning ward Imam Al - Hussien medical city in Sacred Karbalaa governate. It had been obtained 8 isolates (34.78) % from Pseudomonas spp., 7 of them were Pseudomonas aeruginosa and one was P. oryzihabitans , 4 isolates (17.39) % were Acinetobacter baumannii, 4 isolates (17.39) % were Klebsiella pneumoniae, and one isolate (4.34) % of Proteus mirabilis, Escherichia coli, Serratia liquefaciens and Chryzeobacterium meningosepticum and two isolates (8.69) % of Staphylococcus aureus in addition to one isolate (4.43) % from Candida guilliermondii yeast.2 - Chlorhexidine disinfectant and tannic acid were used in preparation of the two hybrid nano compounds after intercalating each of them on layers of double hydroxide (Mg/Al - LDH). FT - IR spectrum studies has shown the appearance of specific chemical groups and the disappearance of others while the spectrum of x - ray(XRD) has shown the appearance of new levels of diffraction in the spectrum of the hybrid nano disinfectant Mg/Al - CHX - LDH and the spectrum of the hybrid nano tannic acid Mg/Al - TA - LDH as compared to the spectrum of the Mg/Al - LDH, which indicate that the two prepared compounds under study is a nano hybrid compounds. Results of the scanning electronic microscope has shown, the change in the shape of the surface of the nanohybrid compounds that prepared above as compared to the layer of double hydroxide. It turns out from the results of the examination with the use of Atomic Force Microscope (AFM), that the diameter of the particles of hybrid nano disinfectant and hybrid nano tannic acid were (121.66 and 77.70) nm, respectively. 3 - The inhibitory activity of the hybrid nano disinfectant Mg/Al - CHX - LDH and the free disinfectant (Free CHX) has been studied and the results revealed followings : a. The hybrid nano disinfectant has the highest inhibitory activity against the two bacterial isolates P. aeruginosa (11 and 23 - A) with an inhibition diameter of 24 mm for each, while the inhibition diameter for the free disinfectant was 23.5 mm against the isolate P. aeruginosa 4 - C.b. The hybrid nano disinfectant showed the highest inhibitory activity against the two isolates A. baumannii (16 - A and 31 - A) with an inhibition diameter of 18 mm for each, while the highest inhibition activity for the free disinfectant was against the isolate A. baumannii 22 - B with an inhibition diameter of 19.5 mm.c. The hybrid nano disinfectant showed the highest inhibitory activity against the isolate K. pneumoniae (16 - B) with an inhibition diameter of 24.5 mm, while the highest inhibition activity for the free disinfectant was against the isolate K. pneumoniae 15 - B with an inhibition diameter of 24.5 mm also.d. The highest inhibition activity for the hybrid nanoic disinfectant against each of bacteria P. mirabilis and E. coli with an inhibition diameter of 23.5 mm, while the highest inhibitory activity for the free disinfectant was against the bacteria E. coli with an inhibition diameter of 24.5 mm, while the bacteria C. meningosepticum was the least affected among the other types of the isolated bacteria with an inhibition diameter of 8 mm and it was resistance to the hybrid nano disinfectant.e. The highest inhibition activity for the hybrid nano chlorhexidine was against the isolate S. aureus 21 with an inhibition diameter of 28.5 mm, while the highest inhibition activity for the free chlorhexidine was against the isolate S. aureus 22 - A with aninhibition diameter of 31.5 mm.f. The inhibitory activity of both the hybrid nano and the free disinfectant against C. guilliermondii yeast was closely to each other with an inhibition diameter of (28 and 29) mm, respectively.4. The study of antioxidant activity confirmed the following : a. Using free radical scavenging method, the IC50(Half maximal inhibitory concentration) value against ABTS free radical were at 10 µg /ml for free tannic acid while it was at 125 µg /ml for the hybrid nano tannic acid Mg/Al - TA - LDH.b. Measurement of ferric ion reducing power revealed that free tannic acid had reducing power greater than that of the hybrid nano tannic acid

Abstract: اجريت هذه الدراسة للتحري عن الفطريات المسببة للامراض الجلدية في الانسان حيث تم جمع 100عينة من الاشخاص المشكوك باصابتهم بالفطريات الجلدية من المرضى المراجعين لمستشفى الديوانية التعليمي من بداية تشرين الاول 2013 وحتى نهاية مايس 2014 وكانت هذه النماذج ماخوذة | This study was conducted to investigate the fungi that causes skin diseases of human. One hundred samples were collected from people who suspected to infect with fungal skin disease from patients coming to Al - Diwaniya teaching hospital from beginning of October 2013 till the end of May 2014. These samples from (skin, hair and nail). All samples that taken from patient were subjected to direct examinations by using wet touch of (KOH 10%) solution. At the same time the samples were grew on sabroud media to determine the type of fungal skin diseases of human. The direct examination shows positive results of 72 samples which represent 72% while for laboratory growth results, its shows 65 samples with positive results 65%. There are three types of Trichophyton fungus had been isolated which are T.rubrum 28 isolates, T.mentagrophytes 16 isolates and T.schoenleinii 4 isolates and there was one type of genus Microsporum which is M.canis 24 isolates. The results show that Tinea corporis infection is the common and its more among females than males where it is 26.39% and 13.89% respectively, then Tinea capitis which is 19.4% in males which is higher than in females which represents 13.89% while Tinea unguium was in females more than males which was in females 16.67% while in males 9.72%. The percentage of fungal skin infection was differ according to the location where the number of infections in the rural area for all types of Tinea were more than the number of infection in the urban area where the number of infected people with Tinea corporis was 18 which represent 25% while in the urban the number was 11 which represent 18.28% while the number of infected people with Tinea capitis in the rural area were 16 which represent 22.22% and the infected in the urban were 8 which represent 11.11%. While Tinea unguium the number of infected people in the rural 10 which represent 13.89% and in the urban 9 people which represent 12.5%. The diagnosis of isolated fungi depended on phenotype of fungal growth and microscopic examination, in addition to special tests for diagnosing skin fungal infections. Also the PCR was used for diagnosis and the work had been completed by using genotypic tree for fine diagnosis and detection the fungal species. The result were send to the genes bank site to be sure about the fungus type through comparison with the registered fungi in this site and by using MEGA6 program for genetic tree analysis of type (unweighted pair group method with arithmetic mean). The results of analysis shows clear converge of local Trichophyton spp. Isolates with Trichophyton rubrum in comparison with other types that appears in the genetic tree analysis while Microsporium diagnosed through genetic tree analysis of type (up GMA tree) and the result of analysis shows clear converge of local Microsporium spp. Isolates with Microsporium canis compared with other types of genetic tree analysis. The effect of silver nanoparticles that is used against growth of T.rubrum, T.mentagrophytes and M.canis. The results show that all the concentrations used were effective in stopping of growth of T.mentagrophytes when deal with the standard measure when dealt with concentration of 4 mg/l the more effective in stopping of radiating growth of the fungus. Regarding the fungus T.rubrum the concentrations of 4 mg/l more effective in stopping of growth while there was no difference for 1mg/liter concentration. Regarding the fungus M.canis, the mentioned concentrations had large effect on fungal colonization growth compared with the standard and this fungus more than other fungi affected by nano silver ions

Abstract: هدفت الدراسة الحالية الى معرفة بعض تاثيرات المستخلص المائي لنبات اللهانة ((Brassica oleracea على مستويات هرمونات الغدة الدرقية الثايرونين ثلاثي اليود Triiodothyronine (T3) والثايروكسين (Thyroxine (T4والهرمون المحفز للدرقية Thyroid stimulating hormone (TSH | The aim of the present study was to investigate some effects of the aqueous extract of cabbage (Brassica oleracea L) on the Thyroid hormones concentrations Triiodothyronine T3, Thyroxine T4 and Thyroid stimulating hormone (TSH), Body weight rate, and some physiological and biochemical parameters such as the total count of leukocytes (WBCs), packed cell volume (PCV) and concentrations of Hemoglobin (Hb), Glucose, Total Cholesterol(TC), Triglycerides (TG), High Density Lipoprotein (HDL - C), Low Density Lipoprotein (LDL - C), Very Low Density Lipoprotein (VLDL - C), Phospholipids, Atherogenic indices levels, Uric acid, Total protein, Albumin, Globulin, Serum Creatinine Blood urea, glutathione(GSH), Malondialdehyde(MDA), Peroxynitrite radical(ONOO - ) Ceruloplasmin(Cp), Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) in sera of male rabbits exposed to oxidative stress induced by hydrogen peroxide (0.5%) with drinking water along the period of experiment (30) days, with comparison the effect of the cabbage extract with the effect of carbimazole (anti - thyroid drug) to induce Hypothyroidism.For the purpose of this study, preliminary experiments were carried out to find the most effective dose of the cabbage extract and this dose was (300 mg/kg body weight).Rabbits (8 - 10 months age) and (950 - 1560 gm weight) were determined randomly divided into five groups, each group includes five replicates These groups are : The control group, cabbage aqueous extract group, cabbage aqueous extract and H2O2 group, carbimazole drug group and H2O2 GroupThe results showed the following : 1 - Treatment the animals with cabbage aqueous extract caused significant decrease (P<0.05) in Hb, PCV and concentrations of T3 hormone, T4 hormone, TC, LDL - C, phospholipids, second atherogenic index, blood urea, serum creatinine, albumin, MDA, (ONOO - ) radical and Cp, While it caused significant increase in weights, TSH hormone, TG, VLDL - C, glucose, globulin and GSH compared with the control group. While no significant variations were observed in total (WBCs) and concentrations of AST, ALT, HDL - C, atherogenic index (first and third), uric acid and total protein compared with the control group. 2 - Treatment of rabbits with carbimazole drug showed significant decrease in levels of body weight, Hb, PCV, and concentrations of T3 hormone, HDL - C, blood urea, albumin, glucose, GSH and Cp. This treatment showed as well a significant increase in T4 hormone, TSH hormone, ALT, TG, uric acid, VLDL - C, serum creatinine and atherogenic indices levels, Whereas showed no significant variations in total (WBCs), AST, TC, LDL - C, phospholipids, total protein, globulin, MDA and (ONOO - ) radical compared with the control group. 3 - Compared with the control group the oxidative stress induced by H2O2 caused significant decrease in concentrations of Hb, T3 hormone, HDL - C, albumin, GSH and Cp, While this stress showed a significant increase in total (WBCs), T4 hormone, ALT, TG, VLDL - C, phospho - lipids, atherogenic indices levels, serum creatinine, glucose, MDA and (ONOO - ) radical. However no significant variations were observed in weights, TSH hormone, PCV, AST, TC, LDL - C, uric acid, blood urea, total protein and globulin compared with the control group.4 - The Treatment of rabbits under oxidative stress with cabbage extract showed significant decrease in Hb, PCV, T3 hormone, TC, LDL - C, phospholipids, atherogenic indices levels, blood urea, serum creatinine, albumin, GSH, MDA, (ONOO - ) radical and Cp comparison with the control group. While a significant increase was observed in weights and concentrations of T4 hormone, TG, HDL - C, VLDL - C, uric acid, glucose and globulin, While no significant variations showed in total (WBCs), TSH hormone, ALT, AST and total protein comparison with the control group.The study results revealed that the effect of cabbage aqueous extract was better than carbimazole effect as antithyroid and as antioxidant role by reduction the harmful effects of the free radicals through some improvement was observed in many physiological and biochemical activities in the body and may be used in protection and treatment many of pathological cases specially Hyperthyroidism, cancer and cardiovascular diseases.
