Abstract: تضمنت الدراسة اجراء عدد من الفحوصات البيئية والبكتريولوجية على عينات الصخور ومياه النضح البالغ عددها 100 عينة والماخوذة من بعض كهوف المنطقة الشمالية في العراق التي شملت بهيري, شرانش, خنس, بجيل وانشكي للفترة ما بين تشرين الثاني - 2010 لغاية نيسان - 2011.ت | This study was included some of ecological and bacteriological tests on rocks and dripping water samples which were included 100 samples taken from some of north region caves in Iraq including Beherii, Sharanish, Khanas, Bejeel and Inishky from the period between November - 2010 to April - 2011.The results of ecological tests which represented with cave environment temperature were ranged from (13 - 24)?C and dripping water temperature were ranged from (11 - 20)?C while the results of pH values for the same sample shows simple variation between (7 - 8) for dripping water and (6 - 9) for the rocks samples. The results of geological screening and mineralization by using X - Ray Fluorescence and X - Ray - Diffraction showed that Beherii cave was mainly composed of manganese with 102 ppm comparing with other caves. While the concentration of iron and sulfur oxides were very low for all caves. The rocks of Beherii and Khanas caves were mainly composed of Dolomite (CaMg (CO3)2), Sharanish cave was composed of Calcite (CaCO3) and Dolomite with the closed ratio, while the rocks of Bejeel and Inishky were composed mainly of Calcite. The isolated bacteria in this study were identified according to cultural and morphological characteristics and biochemical tests, while the bacillus species were identified by using Microgen Bacillus Id System. Twenty two bacterial isolates were identified from total samples. There were nine (9)identified isolates from Beherii cave with 40.9% including Arthrobacter spp., Lysobacter spp., Caulobacter spp., Bacillus freudenreichii and Bacillus subtilis in with 4.5% for each isolate, while there was 18.1% of Methanogenic bacteria with its four genuses including Methanobacterium spp., Methanobrevibacter spp. Methanospirillium spp. and Methanosata spp. In Sharanish cave there was one isolate of sulfur oxidizing bacteria with 4.5 % from the total isolates. Three isolates were identified from Khanas cave included Pseudomonas spp., Xanthobacter spp., Clostridium spp. with 4.5% for each isolate. In addition, it was obtained from a cave Bejeel on six isolates included Bacillus lichiniformis, Bacillus lentus and 2 isolates of Bacillus cereus group, Streptomyces spp. and Gallionella spp. with 4.5% for each isolate and Merismopedia spp., Myxococcus Xanthus, Clostridium spp. were Isolated from Inishky cave with 4.5%for each isolate. The relation between some of bacterial species were studied by detection of the lytic ability of Lysobacter spp. and Myxococcus xanthus for Arthrobacter spp.The microbial role in caves were studied by detection of the ability of some isolated bacteria in Calcium Carbonate (calcite) formation and estimatation of calcite production, Xanthobacter spp. was the highest productive bacteria which gives0.2073 gram during 14 days comparing with other bacterial species.In addition, the effect of temperature and pH on calcite formation by Bacillus freudenreichii were studied, the results showed variation on calcite shape in 20?C and 30?C while the highest value of calcite production in pH.8 was 0.1336 gram comparing with pH.9 with 0.0190 calcite gram. The study also detected the ability of some isolated bacteria to oxidize of iron, manganese and sulfur, where Streptomyces spp. Gallionella spp. and one isolate of bacillus cereus group have shown the ability of oxidize iron on leptothrix medium while Bacillus freudenreichii, Bacillus lichinformis, Bacillus lentus, one isolate of Bacillus cereus group and Streptomyces spp. have shown the ability to the oxidize of manganese on Krumbein and Altmann Agar Medium. In addition, sulfur oxidizing bacteria has shown ability to oxidize sulfur on M.S. Agar and produce sulfuric acid as a product of the oxidation process.

Abstract: The cotemporary world witnesses currently a rapid change due to the challenges imposed by the information technology in all scientific aspects.Hence, the scientific knowledge has become a prerequisite for each individual in this world. This led to a new view on education, in that it is no longer to be a process of providing information but it is a technique for a better learning.However, the main goal of education has shifted to focus on how to make the student to think appropriately and how to utilize the skills of the scientific thinking in order to motivate their thinking and understanding of knowledge as well as discovering the facts and relationships concerning the scientific phenomena aiming to form the generalities. The problem of the current research is mainly concerned with specifying the classical methods adopted in the Iraqi schools which do not match the contemporary scientific development. This research aims at utilizing the strategy of the strategy of forming generalizations according to Helda Taba Inductive Model as a teaching technique in order to identify its effect on : 1 - achievement in Biology.2 - the skills of the scientific thinking of the Fifth - Year female pupils.For sake of achieving the above two aims, two null hypotheses have been formed as follows : 1 - There are no statistically significant differences at level of significance of 0.05 between the mean scres of the female pupils (the experimental gronp), who have been taught according to the strategy of forming generalizations the strategy of forming generalizations, and the mean scores of those female pupils who have been twght classically in the achievnent test. 2 - there are no statistically siguificant differences at level of significance between the experiemental group, who have been taught according to the strategy of forming generalizations, and the mean scores of those female pupils who have been taught classically in the test of the scienhific thinting skills. In order to verify the above two hypotheses, the researcher has conducted an experiment which lasted for one whole academic semester.This experiment inluded : - The lesson plans. - The scientific thinking skills test (30 items). - An achievement test (60 items).The discrimination and difficulty power as well as the alternative action of the two test have been computed.Moreover, validity and reliability of the two tests have been secured. The reliability of the scientific thinking test has been found out to be (0.75) and the reliability of the achievcment test has been found out to be (0.92). This was done by using koder Richardson formula - 20. The researcher has prepared an experimental design, comprising two groups, the first one of which is called the experimental group which is to be taught according to the strategy of forming generalizations.While the second group is called the control one which is to be taught classically. The sample of the study covers (46) female pupils at the fifth - year secondany school (scienbific branch).The whole sample have been randomly distributed into two groups, the experimental one is of (24)pupils and the control one is of (22)pupils. The equalization between the testees in the variables of age, intelligence, exinformation, previous achivement in Biology and the scientific thinking skills has been conducted. The experiment group was conducted at the second academic semester (7weeks).The researcher himself had taught the two groups.The results obtained has been statistically analyzed by using two - indepenbent samples t - test.The results gained showed a better performance of the experimental group more than that of the control one in the scientific thinking and the achievement tests. In the light of the above results, the researcher reconmends the use of the strategy of forming generalizations in accordance to Helda Taba Inductive Model.Also, the researcher recommends to conduct other studies and research on other subjccts other than Biology on different school stages to find out the impact of the strategy of forming generalizations on thinking skills.

Abstract: تضمنت هذه الدراسة اختيار خمس محطات اربعة منها على نهر دجلة المار بمدينة سامراء بعد جسر سامراء والمحطة الخامسة والتي تمثل رقم 2 على مياه مجاري سامراء قبل ان تصب في مياه نهر دجلة.وقد تم اخذ العينات للمدة من شهر تشرين الاول 2010 حتى نهاية شهر ايلول 2011 وقد | The study included chosen five stations for water sampleing, four of them at Tigris river while the fifth station was chosen at samara sewage before meeting with Tigris river.Samples were collected monthly started from October 2010 until the end of September 2011. The study included the study of some physical, chemical and biological characteristics for river water and sewage and noticed the effects of sewage water on quality of these water in Tigris River, these characteristics clued in air , water temperature, electrical conductivity, pH, total dissolved solid, Total Suspseneded solid, dissolved oxygen(Do), biological oxygen demand (BOD), total hardness, calcium and magnesium hardness, chloride, alkalinity, nutrients concerteration, ( phosphate, nitrate) in addition the total number of bacteria and coliform bacteria.Water Temperature ranged through out the study ranged between (5° - 35°), while air temperature ranged between(5° - 38°) , Electrical Conductivity in the river ranged between (280 - 1480) mc/cm, where in sewage the electrical conductivity ranged between(1200 - 2180) mc/cm, while pH value tened to be slightly alkaline, it show very close value where ranged between(5.3 - 8.8). It was noticed that the pH value tened to be slightly acidic from January to August 2011. The results also show that the water were in good airation where the value of dissolved oxygen ranged between (3 - 10) mg/L in station one and stations five while the value of dissolved oxygen in stations two and three range between (2 - 6.5) mg/L.The result also showed that the concentration of total suspended solids ranged between(20 - 798) mg/L. where it has high value in April in all stations, this propably due to increase of discharge of the river which accompanied by suspended solid, while the dissolved solids in all station range between (250 - 1470) mg/L.The highest value recorded were, 1470 mg/ L on May 2011in station two.The value of total hardness for Tigris river ranged between hard to very hard(125 - 360) mgCaCO3/L in station one, four and five, whereas its value in stations two and three ranged between (200 - 925) mg/L. Calcium ion which is the cause of calcium hardness was higher than magnesium cencenrteration which is responsible of magnesium hardness, where calcium hardness ranged between (75 - 587.5) mg/ l and magnesium hardness ranged between (5 - 500) mg/l. chloride concentration ranged between (8 - 127.5) mg/l in all station, chloride cencetration in stations one, two, and five were in the allowable wnorld limit(8.5 - 68) mg/l. Alkalinity results showed that it related to carbonate and bicarbonate, and its ranged between (110 - 900) mg/l.While phosphate value ranged between(0.0106 - 1.999) µg atom - PO4/L, the lowest values were recorded in Tigris river, While the high value recorded in sewage station two, while nitrate value were fluctuated in all stations but the high value recorded in the second station is ranged between (0.0103 - 1.140) µg atom NO3/l. Result of microbiological study shown that there is high number of bacteria the average of total count of bacteria were(39.7×105، 17.31×105، 267× 105، 3.17 ×105، 0.0531×105) cell/ ml for all stations respectively, so it has been suggested that the water in Tigris river considered as polluted to very polluted while the resulty of Coliform bacteria were very high and the average number for all stations respectively as follows (209 × 105, 9809×105 , 25× 105, 1×105, 0.004×105 ( cell /ml According to these result the water is not suitable for direct drinking.Statistical analysis for most factors studied show significant differences between station one and station two and between station one and station three as well in stations four and five and there is no significant differences between station two and station three.

Abstract: تعد الاصابة بقبل الارتعاجPre - eclampsia من الاعتلالات الخطيرة التي قد تظهر في الثلث الثالث من مدة الحمل اذ تتصف هذه الاصابة بارتفاع ضغط الدم وظهور بروتين الالبومين في الادرار. وقد ظلت اسباب نشوء هذه الحالة غير واضحة المعالم, اذ اعزيت بعض من اسبابها الى ا | Preeclampsia is considered as one of the serious complication in the third trimester of pregnancy. It is associated with hypertension and proteinuria. The causes of preeclamptic are still not well understood. Evidences suggested the involvement of metabolic related mutations in the disease. In the current study, the genetic mutations of CBS and MTHFR genes are studied as markers for the diagnosis of preeclampsia. Sixty preeclamptic pregnant women and forty healthy pregnant women as control group diagnosed by the physicians at Azzahra Teaching hospital for obstetrics &pediatrics in Najaf province from December 2012 to August 2013 The poly merase chain reactions technique was used to evaluate the incidence and frequency of C?S &MTHFR mutations. A questionnaire was conducted to obtain the information of the patients and the control group. Genetic mutation were detected by polymerase chain reaction (PCR)and agaros gel electrophoresis. The information indicated that the age of pregnant women, gestation age, previous history of the patients, family history and parity are involved in the pathogenesis of preeclampsia. The results of the present study of preeclampsia showed a significant increase (P ? 0.01) in patients (25 - 34) years old when compared with the other group. where the results found a significant increase (P <0.01) of Preeclampsia occurred during (33 - 39) weeks of pregnancy. And in the patients with previous history for preeclampsia there was significant increase (P<0.001) compared with healthy pregnants. Pregnants with preeclampsia in the family history showed significant increase (P< 0.01) as for women pregnant for the first time showed and significant (P<0.01) and constituted 8% pregnanst with preeclampsia who had diabetes mellitus. The extraction and quantification of cell free fetal DNA (cff DNA) revealed a significant (P<0.0001)increase in preeclamptic patients when compared with those of healthy pregnant women. It is confirmed by the use of an internal negative control through the monitoring of SRY gene (Y chromosome gene) amplification that the gene belong to the infant and 40 pregnant woman were followed up till the labor. Thus, 9 of them had delivered males, while 30 had delivered females. The wild type SRY gene band was obtained clearly from those of male delivery, but not from those of female delivery. Mutations of C?S gene were analyzed by theuse a primer intended to amplify a fragment of171 bp.The rate of mutation was found to be 51.7% and 5% in preeclamptic patients and healthy pregnant women respectively and Odd Ratio=20.31, P value=10 - 7. The C677T mutation of MTHFR gene was verified by the use of a primer designed to amplify a fragment of 198bp. The prevalence of mutation was indicated to be 68.3% and 17.5% in the preeclamptic patients and healthy pregnant women respectively and Odd Ratio =10.17, Pvalue =6.2*10 - 7. Results demonstrated the wide involvement of C?S and MTHFR gene mutation in the pathogenesis of preeclampsia, but they are no crucial for the development of the disease. In addition there are so many factors thatmay be involved in such development.

Abstract: This study was carried on 145 patients infected with leishmaniasis including; 75 with CL, 70 with VL, attending Al - Karama Teaching Hospital, Central Public Health Laboratory and Central Pediatric Teaching Hospital, during the period October 2013 to February 2014 were enrolled in this study, in addition to 30 healthy control collected from the National Center for blood donation for the same age groups for a group of patients. No clinical autoimmune manifestations such as arthralgia or cutaneous vasculitis were reported in any patients. Based on direct skin smear examination and serum samples analysis, the patients were distributed into two clinical groups : 30 patients suffering from cutaneous leishmaniasis and 30 patients suffering from visceral leishmaniasis patients.The presented study aimed to confirmation of diagnosis cutaneous leishmaniasis depending on direct skin smear and visceral leishmaniasis based on indirect immunofluorescent assay test IFAT, then investigate the association of IgG autoantibodies against some antigens, especially : nuclear antigens, like : ds - DNA, nucleosome, histones, SmD1, PCNA, ribosomal P0, SS - A/Ro60kD, SS - A/Ro52kD, SS - B/La, CENP - B, Scl70, U1 - snRNP, AMA M2, Jo1, PM - Scl, Mi - 2, Ku and against cardiolipin, in order to correlate the types of diseases presentation (cutaneous or visceral) with the presence of these autoantibodies in a sample of Iraqi patients.The study was reached to the following results : 1. The direct microscopically examination of skin smear in CL patients, showed positive results in 30 cases (40.0%) compared to 45 cases (60.0%) negative results, and was a significant difference at the level of (P?0.05).2. The anti - leishmanial antibodies by Indirect immunofluorescent assay test in VL patients, showed positive results in 30 cases (42.9%) compared to 45 cases (57.1%) negative results, and was a highly significant difference at the level of (P? 0.01).3. The age groups most affected in CL were 16 to 40 years, with high significant differences at the level of (P? 0.01) were observed when compared with the other age groups. As for patients with VL, who aged between 3 months to 9 years, they showed variable significant differences between age groups in female while there were no significant differences in male at the level of (P?0.01). The majority of patients were aged 3 to 4 years and they represent 9 (30.0%). The study result showed 16 CL patients (53.3%) have only one lesion, while 11 patients (36.7%) have 2 to 9 lesions and only 3 cases (10%) have ? 10 lesions in different sites of their bodies. There were elevated high significant differences at the level of (P?0.01) when compared between the groups. And 21 cases (70%) have infected for ? two months, and the remaining 9 cases get their infection for > 2 months duration. There were increased high significant differences observed at the level of (P?0.01) when compared between the groups. Dry lesions recorded superiority in 20 (66.7%) of the CL cases, and other 10 (33.3%) have been diagnosed as a wet lesions. There were elevated high significant differences observed at the level of (P?0.01) when compared between the two types of the lesion. And The upper limbs were the dominant site of lesions in the CL cases, 15 (39.4%) of the cases had their lesions in one or both hands, followed by the lower limbs in 11 (29.0%) cases and the less frequent site of infection was the face in only 4 (10.5%) cases and 8 (21.0%) cases common lesions. The results showed obvious high significant differences at (P? 0.01) between the groups.4. For the tests of the autoantibodies, the anti - ds - DNA antibody was positive only in one patients (3.3%) with CL of the total (30) patients, while tests of the rest 29 (96.7%) were negative, while in VL of the total (30) patients, 9 patients (30.3%) were positive and 21 (70.0%) were negative. The anti - ds - DNA in leishmaniasis patients were highly significant at the level of (P?0.01) when compared between the study groups. As for the anti - nucleosomes antibodies, it was positive in 5 patients (16.7%) and negative in 25 (83.3%) among patients in CL, while in VL patients, 16 patients (% 53.3) registered positive and 14 (46.7%) their result werenegative, the anti - nucleosomes antibodies in leishmaniasis patients were highly significant at the level of (P?0.01) when compared between the groups study. No score was recorded for anti - SmD1antibodies in CL patients, no one was positive 0 (0.0%) and all the 30 patients (100.0%) gave negative result for this antibody, while in patients with VL, the result showed 4 patients (13.3%) gave positive and 26 patients (86.7%) were negative, the anti - SmD1antibodies in leishmaniasis patients was significantly different at the level of (P?0.05) when compared between the groups. While the anti - SSA/Ro60kD and anti - SSA/Ro52kD, in VL patients, 9 patients (30.0%) scored positive results and 21 of the patients (70.0%) were tested negative for anti - SS - A/Ro60kD, but 7 patients (23.3%) were positive and 23 of the patients (76.7%) were tested negative for anti - SS - A/Ro52kD. While in patients with CL, no one scored positive (0.00%) and 30 of the patients (100.0%) were negative for anti - SS - A/Ro60kD, whereas one patient (3.3%) gave a positive result and 29 of the patients (96.7%) were negative for anti - SS - A/Ro52kD. About anti - SS - B/La we found that 19 of the patients (63.3%) were scored positive result for this antibody in addition to 11 patients (36.7%) who were negative in VL patients and 4 of the patients (13.3%) have those antibodies and 26 of the patients (86.7%) haven’t these antibodies in CL patients respectively. The anti - SS - A/Ro60kD, anti - SS - A/Ro52kD and anti - SS - B/La in leishmaniasis patients were highly significantly different at the level of (P?0.01), when compared between studied groups.5. VL cases showed a significantly different distribution of anti - nuclear antibodies (ANA) in compare with CL cases, especially; in Anti - Ku antibodies 24 (80%), anti - Mi - 2 antibodies 21 (70%) and anti - SS - B/La antibodies 19 (63.3%) respectively.6. The results of anti - nuclear antibodies level in patients with leishmaniasis like; anti - ds DNA, anti - nucleosome, anti - SmD1, anti - PCNA, anti - SS - A/RO 60, anti - SS - A/RO 52, anti - CNP - B were in high significantly different at the level of (P?0.01) and level (P?0.05) when compared between the groups, while the other autoantibodies like; anti - histone, anti - ribosomal P0, anti - Sc170, anti - U1 - snRNP, anti - AMA M2, anti - J0 - 1 and anti - PM - Sc1 showed no significant differences (P?0.01) between the investigated groups.7. The mean value of anti - cardiolipin IgG antibodies was increased substantially with highly significantly differences (P?0.01) in VL patients as compared with control group (8.123 vs. 1.959), also as compared with CL patients (8.123 vs. 2.402).

The serum was separated by the common methods of separation, and conducted thereon desired examinations, The outcomes were as follows : - 1. Superiority of the first and second stages of pregnancy significantly (P<0.05) in the concentration of (Hb, PCV), compared with the third stage. 2. Increasing the total count of white blood cells and the concentration of blood sugar and cholesterol significantly with the progress of pregnancy stages. 3. Increasing progesterone hormone concentration significantly with the progress of pregnancy stages, while the concentration of estrogen hormone decreased in the middle stage of pregnancy, and increased significantly in the first and third stages, whereas there were no significant differences in the concentrations of testosterone hormone during the different stages of pregnancy. 4. The concentration of TSH and T3 hormones were decreased significantly with the progress of pregnancy stages, while the concentration of T4 hormone was increased in the first and last stages of pregnancy.5. Superiority of male pregnancy significantly compared with the female pregnancy in the concentrations of Hb and PCV ratios during the first and second stages of pregnancy, while the opposite happened in the third stage.6. Superiority of male pregnancy significantly compared with the female pregnancy in the total count of white blood cells during the first and third stages of pregnancy.7. Superiority of male pregnancy significantly compared with the female pregnancy in the concentrations of blood sugar, while the female pregnancy surpassed significantly in the concentrations of cholesterol compared with the male pregnancy during all the pregnancy stages. 8. Superiority of female pregnancy significantly compared with the male pregnancy in the concentration of estrogen hormone in first stage, while the opposite happened in the third stage, while the male pregnancy surpassed significantly compared with the female pregnancy in the concentrations of testosterone hormone during second and third stages, as well as superiority of female pregnancy significantly compared with the male pregnancy in the concentration of progesterone hormone during the first and third stages of pregnancy, while the opposite happened in the second stage.9. Superiority of female pregnancy significantly compared with the male pregnancy in the concentrations of TSH hormone during the first stage of pregnancy, while the opposite happened in the third stage. while Superiority of male pregnancy significantly compared with the female pregnancy in the concentrations of T4 hormones during the first and second stage of pregnancy but the concentration of T3 superiority all pregnancy stages.10. A significant decrease in the values of Hb and PCV with increasing the body mass index during the second stage of pregnancy while the opposite happened in third stage of pregnancy.11. Increasing the total count of white blood cells significantly with increasing the body mass index in the first stage of pregnancy, while the opposite happened in the last stage of pregnancy. Increasing the concentration of blood sugar with increasing body mass index in first and second stages of pregnancy but concentration cholesterol decreasing significantly with increasing the body mass index.12. Decrease the concentrations of estrogen hormone significantly during first and second stages of pregnancy with increasing the body mass index for pregnant women, while a significant increase appeared in the concentration of progesterone hormone with increasing the body mass index during the second stage of pregnancy, and the opposite happened during the first and third stages. Testosterone hormone increased significantly with increasing the body mass index for pregnant women during first and second stages of pregnancy 13. A significant increase appeared in the concentrations of TSH hormone at pregnant women with decreasing the body mass index. while a significant increase for the concentration of T3 in first stage and T4 hormone increase at pregnant women during all stages of pregnancy with increasing the values of body mass index.14. No significant differences in values of Hb and PCV during the first and second stages of pregnancy for all ages, but the small ages surpassed significantly compared with the old ages during the third stage of pregnancy. while The total count of white blood cells decreased significantly with the progress of pregnant women's age during all pregnancy stages.15. The small age groups for pregnant women increased significantly in the concentration of blood sugar during the first stage of pregnancy, while they decreased significantly during the second stage of pregnancy.while Age did not affect significantly in the concentrations of cholesterol during the first stage of pregnancy, while the old age groups decreased significantly compared with the first and second age groups) 32 - 24), (23 - 15) during the second and third stages of pregnancy.16. The concentration of Estrogen hormone increased significantly with the age progress during the first and third stages of pregnancy compared with the second stage, while the concentrations of progesterone hormone decreased significantly at old ages during the first and third stages of pregnancy.The concentration of testosterone hormone was not affected significantly during the last stage of pregnancy for all ages, but it decreased significantly during the second stage of pregnancy compared with the first stage of pregnancy for all ages.17. A significant increase showed in for the concentration of TSH in first and the last stages while decreased significantly the concentration T3 and T4 hormones with the age - progress at all stages of age.18.

Atotal of 155 sample from different clinical source has been collected during the period from October - 2012 to March - 2013, these include 20 samples from vaginal smear, 8 samples from saliva and 6 samples from human milk.The results of primary isolation, Laboratory diagnosis and biochemical test showed that 34 isolates has bee identified as L.salivarius.Ahigh precent of isolation has been carried out from human milk which was 40%. The ability of all isolates to produce gelatinase and biofilm has been detected and the results revealed the ability of some isolates to produce gelatinase and biofilm. Ahigh percent of gelatinase production has been detected in L.salivarius isolated from milk sample (50%), while alow percent of gelatinase production was 0% in L.salivarius isolated from saliva. The results of optical density of biofilm produced by L.salivarius isolates from milk which was 100% higher than it in isolates from vaginal and saliva which was 85% and 75% respectively. All isolates shows antibacterial effect against some Gram negative bacteria, the diameter of inhibition as between (2 - 8), the results showed the ability of 4 selective isolates of L.salivarius to produce bacteriocin in which the Rf valve of precipitate bacteriocin was (0.42 - 0.6) compard with leaky bacteriocin hich was (0.57 - 0.8), also leaky bacteriocin as more activity against G - ve bacteria than precipitate bacteriocin. The result of plasmid profile in L.salivarius revealed the presence of megaplasmid in all isolate except one which had one megaplasmid and one small plasmid. Bacterial conjugation between L.salivarius that produce bacteriocin and had megaplasmid which used as adonor cell with E. coli Jm 109 as a recipient cell showed transferring of megaplasmid from donor to recipient cell and the transconjugant cells showed high anti - bacterial effect due to bacteriocin production against G - ve bacteria. The result of amplification of Sal P gene encoding salivracin P by PCR confirmed that all isolate had no Sal P gene in there genetic materials which revealed that these isolates had another type of bacteriocin rather than Salivracin P.

Abstract: This study examined the current survey of the vascular plants of dicotyledon wild during the study period (2013 - 2012) In the area of Sudoor - Diyala, the study was based on the 774 samples of plants with their duplicates as collected by The Researcher. All of these collections have been cacched in the Iraqi herbariums. To be specific there are 186 species which relate to 133 genus and 43 families. All these, have been scientifically classified with thier local and common Iraqi or arabic names.Besides, their duration and economic importance (medical, toxic, nutritional or forage, artificial, harmful, aromatic, ornamental, fuel plants or other uses). Moreover, their geographical distribution in the districts of Iraq and thier geographical existence in neighboring countries to Iraq (Saudi Arabia, Kuwait, Turkey, Iran, Syria and Jordan) , and the study results statistics have shown that the vast majority of the collected species are Herbal Plants totalling 164 species out of 179 species in all.This, in fact, can be ascribed to the impossibility of txonomizing 7 plants species for the incapacity to obtain their flowers or fruits. As for the shrub species it amounts to 13 species where as the number of woody species of trees is 2 only. As for the economic plants and their significance, let s mention the fact that the number of plants used as forage amounts to 86 species, the medical plants are 83 species, the toxic plants fall into 43 species, the ornamental plants are 23 species, the industrial plants are 14 species, the weed plants are 11 species, the aromatic plants are of 6 species, and the plants used as fuel are of 4 species. It also appears that the majority of the plant in the area of study is widespread in the various districts of Iraq, i.e. the number of such plants amounts to 110 species, however, there are plants of medium spread in the districts of Iraq, i.e. the number of such plants amountsto 54 species.There still are some plants whose geographic distribution has no been identified in the districts of Iraq and their number is 15 species, and as for their geographic extension into the neighboring Countries, these plants amount to 116 species in Saudi Arabia, 84 species in Turkey, 81 species in Iran, 79 species in Kuwait, 69 species in Syria and 26 species in Jordan. Furthermore, the species of plants collected perviously and have not been found during the period of study amount to 32 species and these relate to 13 families.The shrinkage of the vegetation cover in the area of Sudoor is attributed mainly to the drought conditions and the wind soil erosion which the area has undergone in the previous years. Besides, there are some other reasons including the overgrazing, the expansion of agriculture and the unstudied projects of construction, which have resulted in the disappearance of natural plants in the area.

The second treatment for 45 days most significant in decreased of body weight and organs weight if it compared with first treatment in all periodsHistological procedures showed that clinical and histological changes are graduated by the severe of protein deficiency and period of time. The histology investigation for liver showed that congestion of blood vessels accompanied with dilation of central vein and portal vein, and necrosis of the hepatic cells and destroyed the general total structure of liver. The section of kidney showed that necrosis and destroyed in renal tubules and epithelial cells in the lumen of tubules and bleeding in renal tubules and clear shrinkage in glomerulus. There are histological changes in stomach by necrosis and desquamation for gastric cells in both period (30, 45) days, while there are no histological clinical changes in both doses in period (15 days) for exposure. Histological sections of testes showed induction inhibition of spermatogenesis and desquamation of germ cells and congestion in the interstitial tissue and dilation of lumen of seminiferous tubules in both periods (30, 45) days, while there is no any changes in both first and second treatment in period of (15)days.In contrast, the hematological parameters showed that the concentration of Hb, PCV significant decrease (p<0.05) in blood of treatment animals which correlated with protein deficiency compared with control group, and the second treatment for (45) days showed the most significant in the parameters compared with the first treatment and for all periods.Biochemical tests obtain significant decrease (p<0.05) in blood glucose level in both treatment first and second in first period. Also the results showed that no significant increase in first treatment in both periods (30, 45) days compared with control group, while there is significant increase in the level of blood glucose in the second treatment in both periods (30, 45) days compared with the control group. Also did not score a significant decrease (P <0.05) in the total serum protein in thefirst treatment in the first period (15) days, compared with the control group, and found a significant decrease (P <0.05) in the first treatment in the two periods (30, 45) days compared with the control group, while found a significant decrease (P <0.05) in the total serum protein in the second treatment period (15, 30, 45) days compared with the control group.It can be conclusion that the exposure for protein deficiency due to clear clinical histological changes for studied organs and some changes in some hematological and biochemical parameters in white mice which treated with protein deficiency which it causes these symptoms

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.

From 61 patients by two samples per patient, also were collected 228 samples of stool from the laboratory of the Department of parasites by two samples of 114 patients for the period from January 2014 to January 2015. Where shown on biopsy results which were subject to examination by the rapid urease test (RUT) the presence of 60 (98.4%) cases, while there were 23 (37.7%) case of those bacteria being positive related to biopsy was not significant differences between the two tests performed. When the distribution of test results (RUT) and culture according to age group, it appear that the highest percentage of infection was in 50 - 41 age group that which showed the highest percentage on examination (RUT) of the number of infected at 16 (26.23%) cases, either in the culture technique number of infected at 9 (14.75%) cases. But when the results of each of the examination (RUT) and culture were distribution according to the sex of the patient's infection was the higher in the females than males reaching males 28 (45.90%) cases in females of 32 (52.46%) cases for examination (RUT). No significant differences appear between the sexes in terms of infected. While the males in 8 (13.11%) and in the case of females was 15 (24.59%) case for the culture technique it did not show significant differences between the sexes in terms of the patients. While taking stool samples to check the stool antigens, it was found that there are 76 (66.7%) cases diagnosed while the technology for the polymerase chain reaction gene cagA to 49 (43%) cases have significant differences between the tests performed. When distribution the results of each of the stool antigens and polymerase chain reaction technique by age group category the highest infected was in 46 - 55 the age group with the number of 23 (20.18%) people case for screening stool antigens. The test results of the technology polymerase chain reaction showed that highest rate of infection was in the 35 - 26 age group where the number of patients was at 15 (13.16%) case.The results of the stool antigens examination also showed that the infection rate among males was higher than females, 39 males (34.21%) and in the case of females has reached the number of 37 cases (32.46%) casesThat did not show significant differences between the sexes patient. The technical results of the polymerase chain reaction by sex has been the injury was higher in females than males reaching 22 in males (19.30%) cases, while in females was 27 (23.68%) cases did not show significant differences between the sexes in terms of the infected. The results of the study conclude that (RUT) and stool antigen test is the fastest in the detection of infection from the bacteria H. pylori and then comes beyond culture technique for biopsy sample and then polymerase chain reaction for stool samples

Abstract: يعد مرض ابيضاض الدم النخاعي المزمن (CML) من الاورام النخاعية التكاثرية، وينشا نتيجة تكون جين Bcr - Abl (الذي يسمى كروموسوم فيلادلفيا) داخل الخلايا الجذعية المكونة للدم. يؤدي هذا الشذوذ الجيني الى تفعيل متواصل لانزيم التايروسين كاينيز وبالتالي نمو وتكاثر غ | Chronic myelogenous leukemia (CML) is a myeloproliferative neoplasm arises from Bcr - Abl gene translocation (called Ph chromosome) in hematopoietic stem cells (HSCs). This genetic abnormality results in constitutive activation of tyrosine kinase and subsequent uncontrol growth and multiplication of granulocytes. The cornerstone in treatment of CML are tyrosine kinase inhibitors, of which imatinib is the most effectively used. JAK2V617F mutation is an acquired single nucleotide polymorphism (SNP) occurs in JAK2 gene and is associated with many hematological malignancy other than CML. It was thought that the two genetic abnormalities (Bcr - Abl and JAK2V617F) occur mutually; however, growing body of evidences suggested the reverse. This study aimed to investigate the prevalence of JAK2V617F mutation associated with serum levels of alkaline phophatase (ALP) and lactate dehydrogenase (LDH) in Ph+ CML Iraqi patients treated with imatinib. A total of 43 Ph+ CML patients (25 males and 18 females, age range 16 - 80 years) who attend Iraqi National Center of Hematology for Research and Treatment/Baghdad were enrolled in this study. Each patient has been received at least six month therapy with imatinib. A consent form involving age, gender, height, weight, smoking status, residency and first family relative history of leukemia was obtained from each patient. Besides, blood samples were collected, from which the granulocytes were separated and then DNA was extracted using a ready kit. Two assays were used for detection of JAK2V617F mutation; real time polymerase chain reaction (qPCR) using specific primers and probe, and allele specific PCR (AS - PCR) using specific primers. Total white blood corpuscles (WBC) as well as serum levels of ALP and LDH were measured. qPCR assay revealed 5 patients out of 43 (11.62%) were heterozygous for the muatant allele of JAK2V617F mutation (genotype GT). The concentration of this allele ranged from 0.01% to 0.12%. None of blood sample gave positive result for AS - PCR assay. From the all risk factors, only gender had significant association with the incidence of JAK2V617F mutation. Average total WBC count, and serum levels of ALP and LDH were higher in JAK2V617F - positive patients (9042±1512.55, 146.05±8.028 IU/L and 204±10.85 IU/L respectively) than that of JAK2V617F - negative patients (6039±1772.239, 64.45±40.15 IU/L and 178.33±13.693 IU/L respectively) with significant differences. These results indicate that JAK2V617F mutation can occur simultaneously with Ph chromosome in CML patients, and qPCR is a highly sensitive method for the detection of this mutation. Furthermore, serum activity of ALP can be used as an indicator for the presence of JAK2V617F mutation in CML patients.
