Abstract: صممت الدراسة الحالية لغرض التعرف على التاثيرات السمية الوراثية والسمية الخلوية للعقار ميترونيدازول(MTZ) في الفئران البيض Balb/ C والتاثير الوقائي الذي توفره المعاملة المسبقة بالكركم(CUR) في سمية العقار ميترونيدازول. تم استخدام مؤشرات الوراثة الخلوية (النو | The current study was designed to identify the genotoxicity and cytotoxicity of Mitronidazole (MTZ) and protective effect of Curcumin (CUR) against the toxicity of MTZ in whit mice. Cytogenetic endpoints (micronuclei (MN) and mitotic chromosomes), Productive biomarkers (sperms), molecular cytogenetic biomarkers (comet assay), molecular endpoints (genomic and mitochondrial DNA concentration in liver and spleen and testis) and mutation assessment in mitochondrial DNA (mtDNA) of liver and testis by PCR and restriction pattern were used to evaluate genotoxicity, cytotoxicity of MTZ and protective effects of CUR in white Balb/Cmice. The study was conducted in the laboratories of college of education, college of science in Tikrit university and laboratories in the state company for drugs industry - Samarra - Iraq (SDI). Dosages of 30 and 50 mg/kb.b.wt. of MTZ were tested for genotoxic and cytotoxic and mutagenic effects in somatic and sperms of white mice. The dosages 4.5 and 10 mg/kgb.wt. of CUR were used to study the protective effects of CUR in genotoxicity and cytotoxicity and mutagenecity of MTZ. The current study showed that MTZ has genotoxic effect expressed by high frequency of micronuclei in polychromatic erythrocytes (PECs) which reached 15.5 ± 2.88 with the dosage 30 mg/kg.b.wt. and 21.31 ± 4.2 with the dosage 50mg/kg.b.wt. compared with 7.25 ± 1.88 in negative control. In the study of the protective effects of CUR against genotoxic and cytotoxic effects of MTZ, we observed that in mice treated with the dosage 4.5 mg/kg.b.wt of CUR for 9 days before the dosage 50 mg/kg.b.wt. of MTZ, There were significant p<0.05 decrease in MN frequency which reached 13.25 ± 4.19 compared with 21.31 ± 4.2 for mice treated with the dosage 50mg/kg.b.wt. of MTZ withoutCurcumin. The study showed that MTZ has cytotoxicity expressed by significant p<0.05 decrease in mitotic index (MI) which reached 0.010 in bone - marrow of the mice treated with 50 mg/kg.b.wt. compared with 0.023 in negative control. The dosage 4.5 mg/kg.b.wt. of CUR for 9 days before giving the dosage 50 mg/kg.b.wt. of MTZ resulted in returning of MI in bone - marrow 0.021 to its levels in negative control 0.023 compared with its value which reached 0.010 with the dosage 50 mg/kg.b.wt. of MTZ. The two dosages 30 and 50 mg/kg.b.wt. of MTZ caused significant p<0.05 decrease in total number of sperms which reached 2.4±2.4 and 1.5 ± 0.1 milions simultaneously compared with 6.7 ± 0.9 millions in negative control. More over there were significant p<0.05 decrease in motile sperms which reached 25.2 ± 11.0 and 14.6 ± 10.6 compared with 57.6 ± 8.0 of negative control. Significant p<0.01 decrease in the length of mid - piece and total length of sperm tail with the dosage 50 mg/kg.b.wt. of MTZ which reached 19.2 ± 6.0 and 69.0 ± 6.0 simultaneously compared with 31.6 ± 9.0 and 100.3 ± 15.0for negative control. Treating with the dosage 4.5 mg/kg.b.wt. of CUR for 9 day before the dosage 50 mg/kg.b.wt. of MTZ resulted in the return of mid - piece and total length of sperm tail which reached 29.5 ± 3.0 and 95.0 ± 5.0 close to the levels of negative control 31.06 ± 9.0 and 100.3 ± 15.0 simultaneously. Compared to 19.2 ± 6.0 for the length of mid - piece and 69.0 ± 6.0 for total length of sperm tail in mice treated with the dosage 50 mg/kg.b.wt. of MTZ without previous treatment with CUR. The study of damage levels in DNA with comet assay showed that MTZ induced significant p<0.01 levels of damage reached 45.4 ± 2.36 with the dosage 50mg/kg.b.wt. of MTZ in bone - marrow and 36.8 ± 0.58 in liver cells compared with 9.0 ± 2.12 and 5.2 ± 0.58 simultaneously in negative control. There were decrease occurred in the level of damage in DNA of bone - marrow and liver cells. However it did not return to its levels of negative control 9.0 ± 2.12 in bone - marrow and 5.2 ± 0.58 in liver cells. OTM values reached 26.4 ± 1.29 and 24.0 ± 1.14 in mice treated with the dosage 4.5 mg/kg.b.wt. of CUR for 9 days before the dosage 50 mg/kg.b.wt. of MTZ. However The values of OTM lower than its values in bone - marrow 45.4 ± 2.36 and 36.8 ± 1.66 in liver cells of mice treated with the dosage 50 mg/kg.b.wt. without CUR. In the molecular study, The results showed mutagenic effect of the dosage 50 mg/kg.b.wt. of MTZ in mice mtDNA expressed by novel restriction sites for Bam - HI and Hind - III in liver tissue and SauA3 in testis. The treatment of mice with the dosage 4.5mg/kg.b.wt. of CUR for 9 days before the dosage 50mg/kg.b.wt. of MTZ did not resulted in the inhibition of mutagenesis in mtDNA. In conclusion, results of this study showed that MTZ has genotoxic and cytotoxic effects in white mice and mutagenic effect in mice mtDNA. The dosage 4.5 mg/kg.b.wt.of Curcumin has protective effect against genotoxic and cytotoxic effects of MTZ. on the other hand the dosage 4.5 mg/kg.b.wt. of Curcumin has no protective effect against mutagenicity of MTZ in mice mtDNA.

Abstract: اجريت الدراسة الحالية بهدف عزل وتشخيص المكورات المعوية البرازية Enterococcus faecalis من مصادر سريرية مختلفة، وتقييم التغيرات المظهرية والافات المرضية في بعض اعضاء الفئران البيض السويسرية المصابة تجريبيا لذا تضمنت هذه الدراسة محورين رئيسين هما : الجانب ال | The present study was conducted to isolate and diagnose an Enterococcus faecalis which are isolated from different clinical sources, and evaluate the appearance changes and pathological lesions in some Swiss white mice organs which are infected experimentally, so this study deals with two main aspects : The bacteriological type : The results obtained may be summarized as follows : - The total number of (310) clinical samples were collected from Baquba Educational Hospital and Al - Batol Hospital for Maternity and Children in Baquba city from the beginning of March to the end of September (2009) with various ages and from both sexes, including (82) urine samples from patients with urinary tract infections, (46) vaginal swab from infection of female reproduction system, (45) surgical wound swabs, (38) stool sample from patients with abdominal pains and diarrhea, (32) throat swabs from tonsillitis patients, (25) middle ear swabs, (22) burn swabs, and (20) blood sample from patients with bacteremia and prosthetic valvular heart diseases. The isolates diagnose depended on the cultural and microscobial characteristics and biochemical tests, serological diagnosis according to Lancefield method and assertion diagnosis according to (API - 20 Strep) was done to find (32) isolates of Enterococcus : (28) isolates of E. faecalis (87.5%), (3) isolates of E. faecium (9.4%) and one isolate of E.gallinarum (3.1%). - The sensitivity of E. faecalis was tested against (23) different antibiotics. The isolates showed resistance of about (100%) against Aztreonam, Amikacin, Co - Trimoxazole, Cephalexin and Cefotaxime, while the isolates were sensitive about (100%) against Amoxicillin, Nitrofurantoin, Imipenem and Ampicillin, while they showed a various resistance to another antibiotics involved in this study. - The ability of the isolates for producing the Beta - lactamase enzymes was tested by the standard rapid iodometric method. The results showed the disability of these isolates for producing the Beta - lactamase enzymes. - The production ability of E. faecalis for some virulence factors was evaluated. The results showed the ability of these isolates of adherence to the uroepithelial cells of human's urinary system were (93%), and (82.1%) were bacteriocin producer, and (28.6%) were hemolysin producer, and (43%) were gelatinase producer, and (10.7%) were lipase producer, and (35.7%) were capsule producer, and (14.3%) were cytolysin producer, while none of the isolates under the study showed the ability of haemagglutination.Histopathology type : (4.6 x 106) cell / ml concentration of the bacterial suspension of E. faecalis was used orally on mice and histopathological changes were examined after (3, 5, 7, 14) days of infection, which revealed the ability of bacteria for colonization and causing pathological lesions and many histological changes in the liver, kidney, small intestine and hearts of these animals. The damage in the animal tissues of the second group (treated with Streptomycin and EFU10) was more than that in the third group (treated with Streptomycin and EFS14), and fourth group (treated with EFU10 only). Generaly, the most important histopathological changes were the necrosis in some areas, and infiltration of inflammatory cells in infected tissues. These pathological lesions cause damage and decompose of tissues with distortion of their morphologies.

The epidemiologically which is main to determine the rates of infection as registered in some district of Diyala province in according to the age, sex, and the month of the year so according to the environmental conditions : - 7200 samples of blood collected from many different ages persons from different districts in Diyala. (3009 males, 4011 females) are examined. The study shows a positive cases of 607 distributed among the districts including (Jalawlaa, Bani Saa'd, Baladruz, Baquba, Alodeim amd DeliAbbas) these register a highest percentage of infection in Jalawlaa sub - district about 12.8% and less percentage of infection are in Baquba about 1.3% whiel is register highest percentage of in infection were (>1 - 5) years about 13.2% and lower percentage infection (<5 - 10) years wuth rate 2.4% so the groups of ages (25 - 30) years didn't appear any infections. according to the gender the males are high from the females whom effected with this disease the number of males (432) case with rate 71, 1%. The number of infected females about 175 cases with rate 28.8%.while in the month of years were the male infection are a highest infection in January - 2012, but did not register any infection in (June and July). The environmental condition infective in prevalence the disease between the people whom resident the houses which breed the animals inside, the number of infections are 245 cases from 607 positive cases with rate 40.3%. This was the low rate 4.9% from the infected people because of rats in their hoses. which didn't kill them. 2. The comparison of diagnostic methods of clinical test, laboratory test and serological test, with the molecular methods from the direction of sensitivity and specificity, The studies results appeared the importance of clinical test subtle in case of a similar cases depend on the clinical symptoms there are a highest cases from clinical test that the children suffering from liver magle their number are 176 cases the rate 80.36%, but the lowest cases of clinical test are 59.19% whom suffered from a skin pallor and black. The laboratory tests appeared the blood picture through testing the 350cases whom suspicion in their infection with leishmaniasis, the number of whom suffering from the lower of WBC 73 with rate 34.2%, while the low cases are 6 with rate 2.82% from whom suffering from hipper ESR, but the serological test was IFAT, Dipsrtick, spotkala - azor, ELISA, KA tex LATEX. Diagnostic infection leishmaniasis a best in diagnostic disease is dipstick test it's sensitivity are 95%, but it's specificity 100% but the lowest is the test of LATEX, it's sensitivity 75% and specificity 80%.3. The Molecular methods : PCR technique test clear recently the new highest sensitivity in diagnosis when the number of the parasite are a little in the blood in the infections peoples whom choose in random way. when testing 100 samples of DNA from the infection with cutaneous and visceral leishmaniasis, the number of infected male are 73, But the number of infected females are 27 with leishmaniasis. and studying the relation between PCR diagnosis according to the sex, age, district and environment condition, so as the recognize between the species of the parasite from the sequence Nitrogen basics with number in each species, (the species are L.donovani, L.infantum, L.tropica, L.major) so recognize the vector insect sand fly Morphology by key classification (ph.alexandri, ph.papatasi Ph.sergentasi, and sqauanlpleuris).

Abstract: اجريت هذه الدراسة في مختبرات قسم علوم الحياة في كلية التربية وفي مختبرات مستشفى الرمادي التعليمي العام ومستشفى الرمادي للنسائية والاطفال ومختبرات النظائر المشعة في بغداد للفترة من 1/11/2011 ولغاية 1/5/2012 والتي تضمنت التحري عن فيروس التهاب الكبد نمط B في | The present study has been carried out at the laboratories of the department of biology at the college of Education and the laboratories of the public - teaching Al - Ramadi hospital and Al - Ramadi hospital for women and children and laboratories of Al - Nathaer Al - Mushe'ah in Baghdad for the period from 1/11/2011 to 1/5/2012. The study consisted of the investigation about Hepatitis B virus in the saliva as compared with serum by using the ELISA and Real Time PCR techniques as well as the detection about antigens and antibody to this virus in serum. It also seeks about the liver functions enzymes and evaluating the extent of its importance for diagnosing liver disease resulted that virus. However, the obtained results showed that HBsAg antigen was found in 99.4% and (1.101± 0.335) mean ±SD in serum as compared with 48.6% in saliva with a (0.330±0.278) mean ±SD, that gave a noticeable increase when comparing it with the control group which was (0.0039± 0.0024) and (0.0017±0.0014 ) for serum and saliva respectively. The value of T test for serum and control group was (16.25) , while the value of T test for saliva and control group was (4.18). The proportion of correlation between saliva and serum in ELISA test was equal to (0.361) with high significance of test while the value of T test for them was (28.902) with high significance of test. The results have also stated that the age groups involved in the experiment contributed as being high proportion of infection in the serum, but in the saliva, these proportions were different and it has been found that the high proportion of infection was 53.3% in the group (10 - 20) yrs., While the lowest proportion was 38.4% in the (31 - 40) yrs. Moreover, it has been concluded that the number of males exceeded the number of females, but the number of females was the most infected with HBsAg in the experiment group. However, the total number of males was 91, It was found that 90 males have positive test to the HBsAg in serum with a proportion equals 98.9% whiles 42 males have a positive test to the HBsAg in saliva with a proportion equals 46.1%. on contrary, the number of female was 84 female and all of them had a positive test to the HBsAg in serum with a proportion 100% and 43 females have a positive test to the HBsAg in the saliva with 51.1 % as compared with control group which included 15 males and 10 female. All of them were negative to the HBsAg test in serum and saliva... The levels of HBV DNA were determined in the samples of positive saliva to ELISA test by using Real Time PCR. 95% from tested serum samples were positive to the viral load While in saliva 50% from the samples was HBV DNA positive. The results also showed that soluble antigen HBeAg has been detected in 24 patients with 13.7% from a total 175 patient as compared with the control group that showed a negative result to this antigen. As for the antibodies, it has been found that anti - HBc IgM was found in only 5 patients with 2.5% while anti - HBc IgG was found in 170 patients with 97.2% from the total number of patients. The control group revealed negative result for these two antibodies. The anti - HBeAg was in 150 patients with 85.7% from the total number of patients. There were no positive patients to this antibody in control group. The anti - HBs wasn’t found in any patient but it was found in the half of control group. This emphasizes to immunize against HBV in those members. The results also exposed that there was a noticeable increase in liver enzymes that it was found that ALT the elevated levels of were found in 76% of patients. As compared with the control group which has normal values 100%. As for AST enzyme was elevated in 60.6%, As compared with the control group which was normal 100%.It has been observed that ALP enzyme was elevated with a 38.4% in the experiment patients as compared with the control group which was normal 100%. Finally, the total values of TSB was elevated in 35.5%, As compared with control group which was normal 100% with (0.52±0.19). Nevertheless, it has been noticed that it cannot be judged about the person's blood on the basis that it is healthy in case of absence of surface antigen unless it is certain that his/her blood is free from HBV DNA by using the technique of Real Time PCR - since many patients who heal from past infection or their infection in a time of passive and amounts of HBV DNA can't be diagnosed by using the ELISA technique

Abstract: تضمنت الدراسة الحالية عزل وتشخيص (19) نوع من السيانوبكتريا من عينات مياه وتربة طينية ومن الصخور من (5) خمسة مواقع في مدينة تكريت ضمن محافظة صلاح الدين، وقد تم اختيار ثلاثة انواع من هذه السيانوبكتريا وهي : Anabaena oryzae, Nostoc linckia, Anabaena laxa اعتم | The current study included Isolation and Identification of (19) species of cyanobacteria from water, clay soil and rocks samples, collected from (5) sites in Tikrit, salah Al - den province. Three species were chosen each species represent the environment which collected from it. These species were Anabaena oryzae, Nostoc linckia, Anabaena laxa. The effects of some environment factors on growth and biological products quantity has been studied in the three species above. The effects of the temperature showed that 26°C was the best for growth and biological products quantity than 16°C and 36°C. While the pH effects showed that pH 7.6 was the best for growth and biological products quantity than pH 6.6, 8.6. Three light intensities were used 1250, 2500, 5000 lux were used. The results showed that the light intensity of 2500 lux was the best for daily growth and quantity of extracted biological products. While the study of the effects of addition of macronutrient and micronutrient to Asm - 1 media which used for culturing of the three species of cyanobacteria by replacement of NaCl by NaNO3 in the medium, showed that there is an increase in daily growth and quantity of extracts of biological extracts, also the addition of FeSO4.7H2O and NaNO3 together showed further increase of daily growth and biological extracts quantity. The biological products has been identificated by HPLC - MS, IR and NMR. The results showed the presence of the neurotoxin Anatoxin - a and the hepatic toxin Microcystin in its various forms MCYST - LAba, MCYST - YM(O), [D - Asp3, Dha7]MCYST - LR and MCYST - YA in the biological products of Anabaena oryzae. The results also showed the presence of the hepatic toxin MCYST - YM(O) and [D - Asp3, Dha7]MCYST - LR in the extracts of the two spices of cyanobacteria Nostoc linckia and Anabaena laxa.The results also showed that the Muller Hinton Agar media is better than the Blood Agar media in testing the activity of these extracts in inhibition of the pathogenic bacteria, the method of holes is better than saturated discs, and the solvent DMSO (Di - Methyl Sulpho Oxide) is the better in testing of biological activities, while the filtrate of cyanobacteria did not shown any activity for inhibition of the pathogenic bacteria which include : Escherichia coli, Streptococcus pyogenes, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus Vulgaris, Staphylococcus aureus. The results showed the high capability of inhibition in concentrations of 1000, 2000, 3000 µg/ml of the extracts of the cyanobacteria Anabaena oryzae, Nostoc linckia and Anabaena laxa on the above pathogenic bacteria and some times more efficient than antibiotics used for comparison, and the concentration 3000 µg/ml was the most effective.The effects of biological extracts of the three species in concentrations of (1000, 2000, 3000) µg/kg of body weight on tested albino mice, using injection and feeding methods, was studied. The results showed poisoning nervous symptom for the first few hours, while the results showed hepatic poisoning symptom on the dissecting animals. The anatomic symptoms included changes the colour of the liver to darkening and appearance of necrosis, in addition to becoming lobbed and swollen some times with bleeding.While the poisoning effects on dissecting tissues of livers of the animals showed a simple swollen and some times assured in all of the liver accompanying with increase in growth and cell division, as well as increases in lymphatic cells inside the tissue and in general in liver tissue. The lymphocyte seemed bigger than for normal cell with multi - nuclei in white blood and increase in cell size and destruction of liver tissue. Nostoc linckia was the greater urging for cell division consequently probably more induce of cancer in the liver of the animals, while the biological product of Anabaena laxa showed more poisonous for liver cell than the biological products of Anabaena oryzae, the least effective in cytotoxic and urging cancer cell in liver of the animals.

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: اجريت هذه الدراسة للمدة من كانون الثاني 2011 ولغاية كانون الاول 2011 للمرضى الراقدين والمراجعين لمستشفى تكريت التعليمي وبعض المختبرات الخاصة في مركز المدينة وضواحيها والذين يعانون اعراض مرضية مختلفه ولفئات عمرية مختلفة ترواحت بين اقل من سنة الى 61 سنة، ح | This study was conducted for the period started from January 2011 until December 2011 on inpatients and outpatients of Tikrit educational hospital and some private laboratories at Tikrit city and surrounded suburbs. Symptoms of different diseases among various age groups varies between less than one year to 61 years. The tests used the (ELISA & PCR) and the analysis of the PCR - RFLP to discriminate the infection by assemblage of Giardia lamblia and differentiate between pathogenic amoeba Entamoeba histolytica and nonpathogenic Entamoeba dispar compared with microscopical examination. The result of present study showed that (75) person who represent (37.5%) were infected by Giardia lamblia and (75) person who represent (37.5%) were infected by E.histolytica/E.dispare complex, out of (200) stool samples which have been tested by microscopical examination. Epidemiological study showed no significant difference among the sex for the two species parasites whereas a high percentage for infection recorded in group at age (1? - 10) year for Giardia lamblia and E.histolytica / E.dispar complex reach to (60%, 36%) respectively. Regarding the place of living Giardia lamblia in rural area showed infection rate of (19.5 %), while infection rate by E.histolytica/E.dispar complex reaches (22.5%) in urban area. Statistical analysis shows a high difference of significance according the source of water supply. Tap water showed high incidence for initiating infection which reaches to (93.3%) by G.lamblia and (90%) for E.histolytica/E.dispar complex. For the infection rates and their relationship to the educational level, the results show that the highest rates of infection recorded in non - educated (52%) and (73.3%) of Giardia lamblia and E.histolytica / E.dispar complex, respectively. Depending on the sample texture, the result show that oily diarrhea is more correlate with infection reaches to (33.3%) of Giardia lamblia and the watery diarrhea form 40% by E.histolytica / E.dispar complex, while simultaneous occurrence of both symptom (colic and loss of appetite) are the most symptom synchronized with infection records (44%) for Giardia lamblia and (36%) for E.histolytica / E.dispar complex. The percentage of infection by Giardia Lamblia in this study depends on the test results of the ELISA was (20%), while the percentage of infection E.histolytica/E.dispar complex was (6.7%). Testing has shown sensitivity compared to microscopic examination reaches to (22.6%) and (8%) for both parasite respectively, while the test showed a high specificity which reaches the rate (93.3%) and (100%) for both parasites respectively. Result of PCR showed a percentage of infection by E.dispar about (32%) (64 sample) from the total samples, whereas it does register any cases infection by E.histolytica. By counting the results of the PCR for the three genes (ssu rRNA + TPIA + GDH) they show a total infection by Giardia lamblia which was (10.5%) (21 samples). This study recorded percentage of infection Giardia lamblia depending on the result of the three Genes separately amounted to (4%), (5%), (3%) for (ssu rRNA, TPIA, GDH) respectively. According to the result of the analysis PCR - RFLP for GDH gene by using the enzyme NIaIV, it did not record any infection by Giardia lamblia (assemblage A), whereas (6 samples) recorded (100) by Giardia lamblia (assemblage B), by using the enzyme Rsal to determine the secondary assemblage shows that the total (6 samples) infected there are 5 samples carrying infection by two type of secondary assemblage returning to the assemblage B (assemblage BIII +BIV) and only one sample infected with (assemblage BIV). To determine the assemblage and secondary assemblage for the parasite result compared with amplification of TPIA gene with lysis by enzyme for the resulting amplification for GDH gene, resulting a ratio of (14.3%) for a sample infection by both assemblage (A+B) and secondary assemblage (BIII+BIV) together, and a ratio of (57.14%) infection by assemblage A only and (21.4%) infection by secondary assemblage (BIII+BIV) together and (7.14%) infection by BIV only.

Abstract: اجريت الدراسة في مختبرات قسم علوم الحياة في كلية التربية بهدف عزل وتشخيص بعض انواع بكتريا حامض اللاكتيك ومحاولة اختبار قابلية خلاياها او النواتج الايضية منها وكذلك دراسة تاثير المستويات المختلفة من درجة الحرارة والاس الهيدروجيني في القابليـة التثبيطية لب | This work aimed to investigate the effects of some lactic acid bacteria (LAB) species (cells or their metabolic products) at different temperatures and pH levels on some soil pathogenic or toxin produced fungi species. Six LAB isolates and the identification was depended on the morphological and cultural characterized and biochemical testes, the isolates were determined as Lactobacillus delubricii subsp. delubricii, Lactobacillus delubricii subsp. bulgaricus, Lactobcillus casei, Lactobacillus acidophilus, Leuconostoc mesentroides and Streptococcus thermophilus, and four fungal species Microsporum canis, Trichophyton mentagrophytes, Aspergillus fumigatus and Rhizopus stolinfer were identified. In this study the highest inhibition effect against the above mentioned fungi was shown by L. acidophilus as a significant (P< 0.05) efficacy where the diameter of inhibition zone in case of M. canis, T. mentagrophytes, A. fumigtus and R. stolonifer was 26, 32, 30 and 28 mm respectively. Less inhibition activity was exhibited by Leu. mesentroides and Str. thermophilus while the lowest inhibition was shown by L. delubricii. Results showed also that the temperature optimal for the growth of bacterial species (except L. casei and Str. thermophilus) tested and their inhibition activity was 30 °C. However, temperature of 35 °C was the optimal for the highest inhibitory effect of both L. casei and Str. thermophilus. At 25 °C of studied bacterial species showed decreased inhibitory effect against the tested fungi. Concerning the pH, the present study showed that the highest inhibitory of all tested bacteria species (except L. acidophilus) was at pH 6.5, L. acidophilus showed such activity at pH 5.5. This study revealed that the inhibitory effect of metabolites produced mixture of the tested bacterial species was directly proportional with its concentrate. Where this mixture was used at media concentration of 10, 20 and 40 mg/ml cultural. However, metabolic products from L. acidophilus, Leu. mesentroides and Str. thermophilus was the most effective in inhibition activity compared with the rest of the bacteria species used particularly at 40 mg/ml cultural media

Abstract: اجريت الدراسة في قسم علوم الحياة - كلية التربية - جامعة تكريت من شهر تشرين الثاني 2010 الى شهر تموز 2011 ? وكان هدف الدراسة هو معرفة بعض الصفات الفيزياوية والكيمياوية للمياه المطروحة من شركة مصافي الشمال/بيجي وامكانية استخدامها لري بعض المحاصيل الزراعية ب | This study was conducted at the Department of Biology in the College of Education - University of Tikrit. The study aims at estimating some physical and chemical characteristics of water raised from the North Refineries Company / Baiji and can be used to irrigate some crops after treatment with a number of physical methods. It also aimed at estimating some heavy elements and their impact on the growth of plants that have been studied (tomato, eggplant, sweet pepper, hot pepper). The region from which samples have been brought of the area was Albu Juwaree village that is located in the city of Baiji and adjacent to the company. Besides, it occurs near wide agricultural areas. After estimating some physical and chemical characteristics of water, soil, and the proportion of oil waste, qualities of plants were studied as well as the assessment of (carbohydrates, proteins) and some of the heavy elements and their effects on the growth of those plants.The results showed that the water of industrial waste led to a reduction in the proportion and natural growth of plants. The most affected seeds were the seeds of sweet pepper, where the total percentage of germination was(0%) when infected %)100) and the least affected seeds were the seeds of tomato, where the total percentage of germination seeds was (80%) when water is contaminated (100%). The treatment by filtering has achieved the best germination of seeds of tomato and sweet pepper, where the ratio was (100%). It turned out that contaminated water has prevented the natural growth of those plants in respect to the number and the size of leaves, the length of roots and the weight of fresh and dry leaves. The methods of physical treatment showed that lightening (25%, 50%, 75%) made to the contaminated water led to the removal of the significant effects, especially when lightening was (75%).The results indicate that there is no significant differences in the lengths of the roots of tomatoes and eggplants, except for the root of hot and sweet pepper.While the heavy elements, which was part of the study in this research, beginning with cadmium was at its highest value at the treatment by filtering and less value in (100%). Through the study it was found that the percentage of lead in all studied plants were (0.00) ppm. The Results showed that the contaminated water led to the reduction of the proportion of carbohydrates with the increase of pollution(%100), where the least proportion of carbohydrates was at the treatment by filtering. The results also showed a decrease in protein concentration with the least proportion at lightening and less value in. (25%)The results showed that the water content of contaminated industrial heavy metals studied (cadmium - lead - copper - zinc - nickel) has decreased at all treatment when treated by filtering, as well as for the remaining elements, except lead, which was (0.00) in all plants and all lightening ratios.The results of this study show that treatment of contaminated water with industrial oil waste by physical methods led to minimizing the negative impacts of such water in reducing the percentage of germination and the reduction below the natural growth compared with non - treatment water and showed that the best way of treatment for the best growth of plants were lightening with (75%) and treatment by filtering. The best response to the treatment was tomato and the most resistant to pollution were (tomato and eggplant) and the most affected by contamination and least resistant was sweet pepper.

This technique considered a modern technique in this field.Physical, chemical and biological characteristics of the manufactured sludge were determined and compared with organic fertilizers (I.O.F) imported from republic of Estonia (Available in local markets).T.R.D technique induced dewatering of the treated sludge at ratio48.5 - 61.5% and producing highly sterilized organic fertilizers which was free of pathogenic organisms(bacteria, worms and eggs) with high chemical characteristics comparing with those imported from Estonia. Manufactured organic fertilizers M.O.Fs have allow acidity pH ranged between 7.5 - 7.7 ,. electrical conductivity at range 1630 - 1873, organic matter at ratio 4.56 - 5.35%, with a moderate concentrations of Pb, Cd, Zn.The concentration of N and K was 1.8, 5.96% respectively while the concentration of phosphorus are 350 ppm. Three levels of M.O.Fs were used for corn plants(5, 10 and 20ton/acres). Results showed that all these levels significantly induced increasing for some physiological and morphological characteristics of corn plants compared with those treated by I.O.Fs or control plants. The vegetative dry weight of corn plants fertilized by M.O.Fs were 23.95gm/plant compared with 16.3 and 5.3 gm/plant for plants fertilized by I.O.Fs and control respectively. (M.O.Fs) induced significant increase in nitrogen concentration compared with plants fertilized by I.O.F and control while the concentrations of Pb, Cd, Zn were not affected by using of M.O.Fs on the other hand Pseudomonas aeruginosa and Escherichia coli were contributed in reducing and removing some of pollutants from the sludge at three incubation periods (30, 60 and 90 day). These two species caused significant decrease in pH and EC of the sludge, P. aeruginosas showed the highest removing ratio of nitrogen (93.1%). The cooperation of the two species caused high removing ratio for the Total organic carbon(87.72%) at 60 days and organic materials (90.68%) at 90 days of incubation also showed high removing ratio for phosphors 100%) at 90 days of in cubation.) These two species also caused high removing ratio for pb, Cd and Zn at30 days and P. aeruginosa was more effective in removing Pb, Cd and Zn from the sludge then E. coli.

Abstract: تناولت هذه الدراسة تاثير الحمل في وظائف الكبد وعدد من صفات الدم الكيموحيوية حيث تم جمع عينات دم من نساء حوامل خلال مراحل الحمل الثلاث ومن نساء متزوجات غير حوامل كمجموعة سيطرة، وجرت هذه الدراسة في مركز العلم الصحي للفترة من اب 2008 الى ك 1 2009 وبلغ مجموع | This study took the effects of pregnancy on liver functions and number of biochemical blood characteristics, in which blood samples were taken from pregnant women during the three trimesters of pregnancy and from non - pregnant married women as a control group, and this study was done in The Alam health centre from August 2008 to December 2009, and the number of pregnant women were (120) women while the non - pregnant married women were (40) women, there ages were between 15 - 40 years old. The results of this study showed increase in Body Mass Index for pregnant women with progress of pregnancy compared with the non - pregnant married women givingP value (P<0.01) and there was appearance of specific elevation in Fibrinogen concentration in blood and Serum Albumin and Cholesterol concentration and Triglyceride in pregnant women compared with the non - pregnant married women giving P value (P<0.01). Also the results showed specific decrease in Bilirubin during the three trimesters of pregnancy compared with the non - pregnant married women especially in the third trimester giving P value (P<0.01). Also the results showed specific elevation in liver enzymes represented by Alkaline phosphatase and Aspartate transaminase enzyme and Alanine transaminase enzyme especially in the last two trimesters of pregnancy in comparision with the non - pregnant married women giving P value (P<0.01), but for Malondialdehyde, the results showed specific elevation during the three trimesters of pregnancy compared with the non - pregnant married women in contrast to the Glutathione antioxidants that showed specific decrease during the three trimesters of pregnancy in comparasion with the non - pregnant married women giving P value (P<0.01). And the study showed also the effects of pregnancy on the blood elements, in which there was obviouse decrease in number of Platelets during the three trimesters of pregnancy compared with the non - pregnant married women giving P value (P<0.01). And the Heamoglubin concentration, Red Blood Cell number and the mean corpuscle Volume Suffer Specific decrease during the three trimesters of pregnancy compared with the non - pregnant married women giving P value (P<0.01).

Abstract: اجريت هذه الدراسة التي امتدت من بداية شهر ايار (2007) لغاية نهاية شهر اب (2008) للتحري عن نسبة الخمج بالطفيلي المسبب لداء المقوسات بين النساء المجهضات والولودات طبيعا في بعض مناطق مدينة الموصل والمراجعات لمستشفى الخنساء التعليمي للولادة والاطفال.شملت عي | This study was conducted during the period from May 2007 to August 2008 to investigate the rate of infection with toxoplasmosis among aborted and normally delivered women in Mosul City territories who attending AL - Khansa'a educating hospital.Out of 150 women under study, 50 were aborted while 100 were normally delivered. 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.
