Twenty local adult male rabbits were included this experiment their ages ranged between 10 - 14 months.The animals were treated with oral swallow for 12 weeks. The animals were divided into four groups : control group is treated orally with (0.9%) normal saline; First group was treated orally with 10 mg/kg of body weight sodium fluoride, second group was treated orally with 20 mg/kg of body weight sodium fluoride and third group was treated orally with 30 mg/kg of body weight sodium fluoride. The results of present study showed a significant decreased (P<0.05) in body weight of treated animals with dose of sodium fluoride 20 and 30 mg/kg of body weight, while there is no significant differences in the body weights of treated animals with sodium fluoride dosage of 10 mg/kg of body weight when to compared with control group. The percentage of organ weight to body weight showed a significant decrease in testis weights and liver weight, while there was no significant differences in kidney weight in treated group with sodium fluoride when to compared with control group. Concerning histological changes showed a reduction or freezed stages in spermatogenesis processes which timed with decrease in number of primary spermatocytes and secondary spermatocytes in addition to infiltration of lymphocytes, also found that NaF cause disorganization, denudation, and reduction in germinal epithelial cells of the seminiferous tubules and associated with absence of sperm in the lumina, also showed a decrease in radius of epididymus ducts and decrease in number of sterocilia and decrease number of mature sperms. Histological sections of kidney showed that there was a clear shrinkage of glumeruli.Histological section of kidney of animals that treated with sodium fluoride showed a mild blood vessels congestion, shrinkage in glumeruli, distributed in renal tubules and erode its epithelium with some apoptotic areas. The liver sections appeared appreciable effect with fluoride include dilation in central vein and erode to its epithelium, congestion in hepatic sinusoids with apoptosis and erode to general structure of liver with some of inflammatory cells and death in some cells which lead to erode of typical ray arrangement. Regarding blood parameters the present study showed a significant decrease (P<0.01) in percentage of (PCV) and (Hb) of the animals treated with sodium fluoride, while showed (WBCs) count significant increased compared with control group. Hormonal analysis (Testosterone, T3 and T4) showed a significant decrease, while significant increase of glucose, cholesterol, urea, transaminases enzymes for (AST, ALT) and bilirubin levels. Results obtained from this study and mentioned above may be attributed essentially to that of Naf administration results in sever lesion of male reproductive system wich may be aggravated with increase administration concentration of Naf.

Callus was induced and maintained on Murashige and Skooge (1962) medium (MS) supplemented with 0.3 mg/l Kinetin and 2 mg/l 2, 4 - dichlorophenoxy acetic acid (2, 4 - D) using cotyledons as the source for callus induction. Different concentrations of cadmium, lead and sodium chloride directly or gradually were added to the culture medium as contaminants. Selected tolerant cell lines were subjected to regeneration. Callus showed better tolerance to gradual exposure than direct addition. The concentrations of Potassium, lead, Cadmium and Sodium recorded to 17, 24, 27, 35 ppm when 1.0, 2.0 mg/L and 0.4% of cadmium, lead and sodium chloride were added respectively. The study included the effect of the cytokinin (benzyl adenine, BA) and the auxin (Naphthalene acetic acid, NAA) on the regeneration of shoots from callus tolerant to pollutants reached 76, 87 and 85% for callus tolerant to Cadmium, Lead and sodium chloride respectively, when the combination of 0.7 mg/l BA and 0.2 mg /l NAA was supplemented to the medium. The effect of indole butyric acid (IBA) on rooting of shoots. The concentration 0.7 mg /l gave highest percentage of rooting amounted to 66, 70 and 85% in a medium supplemented with cadmium, lead and sodium chloride respectively. Acclimatization of plantlets using river sand soil recorded 85% survival. The study was also included effects on plant height and fresh weights, shoot fresh weight was superior at the concentration 1.0 and 2.0 mg/l of cd and pb recording 8.7 and 7.5 g respectively. Treatment with NaCl led to increase the root fresh weight recording 19.1 g. Maximum cd accumulation reached 12.5 ppm in shoots, 10.5 ppm for lead in roots, 39 ppm for NaCl in roots. The experimental work investigated the effect of mycorrhiza (Glomus mosseae) on cd, pb and NaCl removal by Sesbania plant when grown in either soil contaminated with cd, pb and NaCl or non - contaminated soil (control). Inoculation with mycorrhiza led to an increase in seed germination percentage (96%), plant height (28 cm) in non - contaminated soil, while achieved an increase in shoot and root fresh weight recording 10.0 and 6.8 g respectively. Inoculation with mycorrhiza also led to a significant increase in cd and pb accumulation in roots reached 9.0 and 87.4 ppm respectively. Meanwhile, Mycorrhiza caused a significant increase in Na accumulation in root system (42.5 ppm) which already affected K concentration as a result of competition with Na recording 16.5 ppm in shoots. Mycorrhiza inoculation led to a significant increase in number of root nodes in non - contaminated soil recording 86%. Finally, mycorrhiza succeded in infecting Sesbania rostrata roots reached 90% in non - contaminated soil while it was 85% in contaminated soil

Four sites selected along the river whithin three provinces; Babylon, Najaf, Al - Qadisiyah. Assessment of water quality done by using Canadian Council of Ministers of Environment (CCME) and Index of Biological Integrity (IBI) for the purpose of determining the validity and quality of its water for the General purpose and for Drinking and Irrigation.The physicochemical properties and biological (Phytoplankton) were studied during the study period. These properties were; temperature of the air and water, light penetration, electrical conductivity, salinity, turbidity, water current speed, total suspended and dissolved solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, carbon dioxide, total alkalinity, acidity, total hardness and ions of calcium, magnesium, sodium, potassium, and the sodium adsorption ratio, chlorides, sulfates, boron, nitrite, nitrate, phosphate, silica and some heavy metals such as cadmium, lead, zinc, copper, chromium, manganese in both phases : dissolved and particulate. results showed that the values of the physical and chemical factors ranged as follows : (7 - 47) C, (10 - 31) C, (14 - 177.5) cm, (1020 - 5600) µs/cm, (0.65 - 3.46) 0%, (0.07 - 129) NTU, (27.03 - 115.57) cm/s, (591 - 2985) mg/L and (0.001 - 0.128) mg/L, (7.04 - 8.8), (6 - 11.8) mg/L, (0.13 - 6.6) mg/L, (8.2 - 53) mg/L, (81.4 - 198) mg/L, (30 - 200) mg/L, (6 - 46) mg/L, (490 - 929.67) mg/L, (83.37 - 290.18) mg/L, (0.79 - 174.84) mg/L, (92.5 - 713) mg/L, (1.9 - 11.18) meq/L, (6 - 133) mg/L, (97.97 - 861.73) mg/L, (329 - 1040) mg/L (0.01 - 4.23) mg/L, (0.008 - 1.33) µg/l, (2.16 - 44.74) µg/L, (0.012 - 0.59) µg/L and (104 - 514) µg/L respectively.Concerning the heavy elements, the values of dissolved cadmium ranged between (undetectable - 0.075 mg/L) and it's particulate between (0.0043 - 0.2705) mg /L and dissolved lead between (undetectable - 0.0232 mg /L) and it's particulate between (0.0045 - 0.148) mg/L and dissolved zinc between (un - detectable - 0.0168 mg/L) and it's particulate between (0.0115 - 0.316 mg/L) and dissolved copper (undetectable - 0.0273 mg/L) and copper is particulate between (0.0062 - 0.063 mg /L) and dissolved chromium between (undetectable - 0.0193 mg/L) and the chromium is particulate between (0.0043 - 0.0449) mg/L and dissolved manganese (undetectable - 0.0256) mg/L and it's particulate between (0.0085 - 0.0739) mg/L.The biological tests include Qualitative and Quantitative Study on phytoplankton and also included calculating the total number of coliform way casting dishes by using the MacConkey Agar media.The number of diagnosed species of Phytoplankton was 295 species, belonging to 74 genera. The Diatoms Bacillariophyceae won the biggest part of it as it formed 160 species and 35 genera any rate (54.24%), followed by green algae (70 species belonging to 24 genera) and green algae (52 species belonging to 11 genera) then Euglenophyceae (10 species belonging to both sexes), while golden brown algae and algae Pyrrophyceae were less algal groups registered as belonging to the two single - sex. Some types of phytoplankton existed in most of the duration of the study, including Bacillaria paxillifera, Cocconies placentula, Cyclotella meneghiniana, Diatoma elongatum, Fragilaria virescence, Melosira ambigua, Synedra acus.The total number of phytoplankton is estimated between (104.9 - 4460.09) cell × 103/liter. An increase in the number of phytoplankton in July and January was observed clearly. The concentrations of chlorophyll - a were ranged between (0.0693 - 9.78 mg /L). While the total number of results for coliform were (5 - 281 × 103) cells/liter, The water quality of the evidence Account (Canadian model) using a number of physical, chemical and Biological properties. The results showed that the waters of the Euphrates are located within categories (Poor - Good) with respect to the public evidence of the quality of water of this river while it was located within categories (Poor - Acceptable) with respect to their use for drinking, While its use for irrigation purposes, it was clear that run river water data fall into two categories (Poor - Good). The results of the analysis of the main components Principal component Analysis (PCA) indicate that the nitrates and the total number of coliform and dissolved oxygen, phosphate, zinc, lead and Biological oxygen demand and pH are the biggest impact on the water quality of the index values of the variables of general purpose.These factors are responsible for the deviation index values, followed by turbidity and total hardness and electrical conductivity and temperature of the water, copper, chromium, and cadmium heat. But with the biggest impact of the index water quality factors for drinking purposes are chloride and electrical conductivity and total hardness, magnesium, turbidity and basal college, sodium, calcium, copper, sulfates, nitrates and coliform, zinc and dissolved oxygen, pH, manganese and lead followed by boron nitrite, cadmium, chromium and vital requirement for oxygen. While the chloride and conductivity electrical, the proportion of sodium, copper, zinc and adsorption of boron have greatest influence on the value of water quality index for irrigation, followed by manganese, cadmium, chromium, lead and pH.The phytoplankton index of Biotic Integrity (P - IBI) has been calculated using ten units including (relative abundance of green algae, green algae, pyrrophyta, Euglenophyta, Xanthophyta, Centralales, pennales, species richness index, the density of phytoplankton and chlorophyll a) The results showed that phytoplankton index of Biotic Integrity values ranging between (47 - 74) in the first position and (47 - 67) in the second location, and (45 - 76) in the third site and (45 - 71) in the fourth site. In other words, phytoplankton index of Biotic Integrity with estimating index (good - poor). The results showed the effectiveness of phytoplankton index of Biotic Integrity values in estimating the environmental changes.

This evaluation revealed that 209 of patients (92%) had vaginal discharge, irritation and itching. Reguested blood samples were taken for laboratory test included estradiol, progesterone and testosterone. The level of these sex hormones in women with Trichomoniasis have been determined and compared with levels of these hormones in control group.In addition high vaginal swab were taken for microbiological tests. and used for diagnosis of Trichomonas vaginalis and other associated microorganisms, the rate of parasitic infection had been determined and it's relation with age group, marital status, level of education and level of vaginal acidity had been estimated. Moreover, the percentage of cases, with pus cells, epithelial cells, red blood cells and clue cells have been estimated. Results : the results of laboratory tests elicited the presence of Trichomonas vaginalis (6.3%). And in addition to it there is bacterial and fungal vaginal infection and the percentages were (54%) and (15%), respectively. Moreover, the results showed the presence of dual infections between the parasite and bacteria, the parasite and fungi, and bacteria and fungi and there percentages were (11.8 %), (8 %) and (4.9 %), respectively.Regarding age group, results showed that the highest parasite infection rate was among women in the age group (26 - 35 years) which was (41.1%), in compare with infection rate in others age group (18 - 25 years) and (36 - 45 years) which were (9.3 %) and (18 %), respectively. Regarding, the marited status, the highest infection rate was founded among married women in comparison with widows, divorcees women, and the percentages were (31.7 %), (6.8 %) and (14.7 %), respectively. Regarding, the educational level, the results showed highest rate of infection with Trichomonas vaginalis was among women with low educational level which was (11.8%) in compared with those with intermediate (7.9%), secondary (4.8%), and tertiary education (1.3%). Regarding, the pH of the vagina, results showed that the rate of vaginal infection were high when pH of vagina > 4.5 in comparison with the lowpH ? 4.5 and the percentages were (83.7%) and (16.3%), respectively. The results of direct smear and cultures showed that (25.9 %) of case (59 patient) were infected with Trichomonas vaginalis, (31.7%) of case infected with E.coli, (27.7%) of case infected with candida albicans, (21.1%) infected with Gardnerella vaginalis, (17.6%) percentages of Lactobacillus spp. (8.3%) percentages of Staphylococcus epidermidas (5.2%) in fected with S. aureus, (3.5%) infected with Enterobacter spp., (2.6%) infected with Proteus spp., (2.2%) infected with Klebsiella spp., (1.7%) infected with Acentobacter spp. and Streptococcus spp., (1.3%) infected with Pseudomonas spp., While the lowest rate was for Neisseria gonorrheae (0.8%). Also results showed that the highest percentage of dual infection with trichomoniasis it was in Gardnerella vaginalis which detected in 22 case (37.2%), followed by Candida albicans, which detected in 18 case (30.5%). While the lowest rate was with Neisseria gonorrheae which detected in one case (1.6%). The other laboratory tests including hormonal estimation in patients with trichomoniasis, the results of current study showed decrease level of estradiol hormone in women infected during follicular and luteal phases of the menstrual cycle, In follicular phase the mean of estradiol was (6.83 pg/ml) in comparison with control group that hormone rate was (42.61 pg/ml). In luteal phase the mean of estradiol was (27.00 pg/ml) comparison with control group which hormone rate was (87.16 pg/ml). In addition to that the level of progesterone have increased in follicular phase but decreased in luteal phase in comparison with control group. In follicular phase the mean of progesterone was (5.89 ng/ml) in com - parison with control group which hormone rate was (0.72 ng/ml). In luteal phase the mean of progesterone in infected women was (0.56 ng/ml) comparison with control group in which hormone rate was (19.83 ng/ml).Regarding, the level of testosterone, the results showed that the level had been increased during the follicular and luteal phases in infected women compared with control group. In follicular phase the mean of testosterone was (3.44 ng/ml) in comparison with control group which the mean was (0.24 ng/ml). In luteal phase the mean of testosterone was (3.65 ng/ml) in comparison with control group in which the mean was (0.30 ng/ml).Conclusion : The presence of infection with Trichomonas vaginalis, and it's associated with other microorganisms that are detected in the current study and other study previous may indicated a correlation between them. So those patient, constantly in need for a panel of laboratory test including : vaginal pH, and hormonal estimation as these factors may play a role in diagnosis and follow - up of the patients.

المستخلص: الصرع هو حالة مزمنة تتميز بنوبات متكررة دون سابق انذار، سببها خلل في نقل الاشارات الكهربائية داخل الدماغ، وعقار Levetiracetam (LEV) من العقاقير المضادة للصرع، ذو خصائص دوائية ملائمة وتظهر فعاليته في تحسين السيطرة على النوبات، ويكون امتصاصه في البلازما سري | Epilepsy is a condition characterized by recurrent abrupt seizures episodes caused by the defect in the transmission of electrical signals to the brain. LEV is one of antiepileptic drugs which has appropriate pharmacological properties and show its effectiveness in improving the control of the epileptic seizers, its rapid absorbance, and its excretion through the kidneys by glomerular filtration and it is re - absorption into the tubular portion.Kidney arise from intermediate mesoderm and it consists of three execratory organs in all vertebrates : pronephros which is transient and present in all vertebrates, mesonephros which also present in all vertebrates embryos and their activity depends upon the type of embryo, and metanephros which is the functional kidney during life after the embryogenesis in reptiles, birds and mammals. The first signals for kidney initiation in albino rat embryo take place in the 10th days of pregnancy. The current study is designed to demonstrate the effect of LEV (350 mg/kg/day) on the kidney development of Albino rat fetus from the age of 8 - 18 days of pregnancy and its effect on the kidneys of the 3 and 7 days aged newborns. In addition to its effect on pregnant rat kidneys treated with the drug for 17 days. Hundred pregnant Albino rat (Rattus rattus) are enrolled in this study, classified blindly to 50 control and 50 pregnant rats are orally treated with LEV (350 mg/kg/day). The histological results of the current study revealed that there is no effect on embryonic kidney in fetuses aged 9 days of pregnancy, whereas, the pronephros of the fetuses aged 10 days shows death of the cells in comparison to control group. Moreover, the kidney of the 11th aged fetuses showed degeneration of the mesonephric duct represented by decrease cellular mass, death and hypertrophy of some cells comparing to the cells of control group. Concerning the kidney of the 12th aged fetuses and subsequent days, there is degeneration of the epithelial cells of the metanephros duct, their detachment from the basement membrane and their congestion in comparison to the cells of the control group. The kidney of the 13th aged fetuses showed swelling, damage for some of the epithelial cells of the glomerulus and collecting tubules, accumulation and shrinkage of glomerular cells, damage, death, and detachment of some collecting tubules cells demonstrated in the 14th aged fetuses. There enlargement of capsular space in addition to the most previous defects was seen in the 15th aged fetuses in comparison to the control group. Most of the previous defects are seen in the 16th, 17th and 18th age fetuses. Scanning electron microscope revealed nuclear enlargement of the podocytes found in the visceral layer of the renal corpuscle of the 16th aged fetuses (mean diameter 64.6 µm compare to 39.2 µm of the control group). Regarding the kidney of 3rd and 7th aged newborns, the histological defects seen in the latest aged fetuses was also seen and there was statistically significant differences (p?0.05) between the diameters mean of the glomerulus of the 3rd and 7th aged newborn. Whereas, there was no significant difference in the diameter of the kidney tubules of 3rd but there was significant difference of the 7th aged newborn. Regarding the kidney of the 17th day treated pregnant rat, there was enlargement of the capsular space caused by accumulation, and degeneration of glomerular cells characterized by loss of the nucleus, shrinkage of the glomeruli, and atrophy of most of them. Loss of the nucleus and detachment of the cells, and swelling of most of the collecting tubules. There was a statistically significant difference between the diameter of the kidney tubules of the pregnant rat and the control group. In conclusion, LEV had histological effect on the kidney of the 10 - 18 aged fetuses and on 3, 7 days aged newborns in addition to its effect on the kidney of the pregnant female treated with the drug for 17 days.
