Isolation and identification of Staphylococcus aureus from clinical samples of wounds(33)20% , burns(13)8% and fasterrs(33)20%,cases in Al - Salaam, Al - Khansah, Abn - Atheer, Ibn Sena, Al - gamhoory hosphtalofMosul city.The study started from Feb.(2007) to Oug(2007). Isolation and identification of bacteriocin producing strains, extraction of produced bacteriocin by competent strains, purification and charachterization of extracted bacteriocin, evaluation of therapeutic ability of extracted bacteriocin against transplanted mammary tumor in white mice females, determination of bacteriocin effect 0n human lymphocytes of whole blood culture and determination .of bacteriocin effect in five of cancer and normal cell lines. The evaluation conducted by : - Determination of chromosome aberration in bone marrow cells, Determination of chromosome aberration in primary spermatocytes, determination of morphological abnormalities in mature sperms, determination of genetic damage in hepatic cells by comet assay, determination of genetic damage in human lymphocytes by micronucleus test and SCEs test, determination of inhibition effect in cancer and normal cells growth result from treatment with different concentrations of bacteriocin for different times. 163 S aureus isolates from 250 samples of wounds , burns and fasterrs ,14/163 has been detected as competent producing isolates, 2/14 isolate showed DNase and plasma membrane damage effect. These two isolates used to produced bacteriocin which used for testing its effects in this study. Free extracted bacteriocin showed stability in storing at 4ºC. Ammonium sulfate used to precipitate the bacteriocin. Separation was conducted by 100G sephadex column. Lypholization and weighing of powder in order to using in LD50 determination and therapeutic treatment and genotoxicity study with 1/2, 1/10 LD50 and dose of 1/100 LD50 and its half dilutions in treatment of cancer and normal cell lines.Chromosome aberrations associate with growth of transplanted tumor in mice females which of two type, structural aberration as chromosome breakage, chain IV and numeric aberration as chromosome attenuation and endomitoses.In vivo treatment with bacteriocin showed chromosome aberration types in bone marrow cells and primary spermatocytes.Chain IV, X - Y univalents and autosomal univalents was observed, polyploidy was observed too.Sperm morphological abnormalities was observed as amorphous head, with out hook, small and big head and banana shape, coiled tail was noticed too.Therapeutic treatment with B6 and B11 bacteriocine caused enhancement of mitotic activity MI and reducing of structural and numerical aberrations. Its total average was 8.4±0.25 after growth of transplanted tumor, after therapeutic treatment was 4.5±0,22 with B6, 2.0±0.005 withB11 compared with 1.8 ±0.009 of negative control, this refer to significant differences at p<0.05. Treatment with the two used doses in decreasing percentage of chromosome aberration its averages decreased from 8.8±0.28 to4.0±0,02 after 3 weeks and to 5.0±0.02 after 6 weeks with 1/10 LD50 and to 5.0±0.02 after 3 weeks, 4.0 ±0.01 after 6 weeks with 1/2 LD50.In vivo treatment of male white mice with the two therapeutic doses 1/10, 1/2 LD50 cause induction of CAs types. Average of total structural aberrations 4.0±0.17, 4.1±0.13 with 1/10 and 1/2 of LD50 respectively with B6, 5.1±0.31 and 5.1±014 with B11 which is significant differences when compared with negative control 2.1±0.1. Average of total numerical aberrations was 8.0±0.3, 8.0±0.2 with 1/10 and 1/2 LD50 respectively of B6, 7.6±0.1 and 8.1±0.17 with 1/10 and 1/2 LD50 respectively of B11 which show significant differences when compared with negative control 1.8±0.009. Treatment caused decrease of mitotic activity (M!), there were significant differences at p<0.05 when compared with negative control 75.6±0.9. It reached 46.6±1.5, 43.0±0.3 with B6 and 38.9±0.2, 37.2±0.3 with B11. Treatment of male white mice induce chromosome aberration types in primary spermatocytes which showed significant differences at p<0.05 of total average of CAs when compared with negative control 1.8±0.17 while it reached 3.4±0.6 and 4.1±0.6 with B6 and 8.2±2.5 with B11.Sperm morphological abnormalities induced by treatment with bacteriocin, it showed significant differences at p<0.05 in total average abnormalities which reached 19.8±0.73 for control while reached 23.0±1.0, 26.8±1.19 for B6 and B11 respectively. Therapeutic treatment caused decrease in level of damage in hypatocytes DNA of tumor carrier mice. Significant differences was observed at p<0.05 in OTM which reached 0.19±0.03 in negative control, 3.73±0.69 in transplanted mice and decreased to 2.16±0.59, 0.998±0.32 after treatment for 3 and 6 weeks respectively with B6. It reached 2.72±0.576, 1.216±0.387 after 3 and 6 weeks respectively with B11. Therapeutic treatment cause significant decrease at p<0.05 in percentage of cells with damaged DNA. Percentage in negative control was 98.5±9.0 and decreased to 87.0±0.78, 58.7±5.88 after 3 and 6 weeks respectively with B6 and with B11 reached to 92.0±8.25 and 64.8±7.21 after 3 and 6 weeks respectively. Treatment of human lymphocytes in whole blood cultures with different concentrations of bacteriocin induce micronucleus formation in dose dependent manner. Its number reached 17 and 13 in 1st and 2nd donors respectively in negative control cultures. High concentrations of bacteriocin caused significant differences at p<0.05 and p<0.01, which reached 33and 35 with 100 and 500µg/ml respectively for 1st donor. Significant increase at p<0.05 resulted in total average of SCEs with 500µg/ml which reached 8.10±0.41 for 1st donor. No significant increase was observed for 2nd donor with B6, while significant increase at p<0.05 and p<0.01 resulted , which reached 9.94±0.35 and 9.54 ±0.33 with 100 and 500µg/ml respectively when compared with 7.14±0.35 for negative control cultures of 1st donor, and 10.68±4.5, 9.74±0.50 with the same concentrations for 2nd donor.When Cancer and normal cell lines treated, Different effect was existed by either of B6 and B11 extract and this depend ed on kind of cells and time of treatment. Similar killing effect of the two extracts was existed with some difference. For the cancer cell line AMN - 3 significant differences at the level P<0.05 in mean of viable cells numbers after 24 and 48 h of treatment with lower concentrations and with the highest concentration after 72 of treatment with the two extracts B6 and B11, that means increased cell resistance with the time of treatment. The mode of effect was different for cancer cell line RD, there were significant differences at P<0.05hn mean of viable cell number after treatment with the higher concentrations for 24 h , the effect disappeared with the treatment of 48 h which returned with the lowest concentrations with treatment of 72 h that refer to the possibility of occurred changes in cells genetic material. The effect of the two extracts in the cancer cell lines Hela which showed no significant differences Between the control and treatment after 24 and 48 h but significant differences at P<0.05 was excited in mean of cell numbers after treatment for 72 h which refer to increased effect in the cells with the durance of treatment, for the cancer cell line AMG - 5 significant differences was excited at P<0.05 in the mean of cell numbers after 24 and 48 the lowest concentrations and with the highest concentration of the extracts B6 and B11 after 72 h of treatment. While for the transformed normal cell line L20B the effect of either of the two extract B6 and B11 was variant which showed significant differences in mean of viable cell numbers after 24 h of treatment with the lowest concentration of the extract B6 and the highest and median concentrations of the extract B11, their the behaviour of this cells was similar with the cells of cancer cell line RD which showed no response after 48 h of treatment with the two extracts which disappeared but it different after 72 h of treat men which refer to increased cells resistance.

Oil residue (used diesel and kerosin engines) was used to polluted Soil with three concentrations 4000, 8000, 12000 part per million and This study was conducted in a protected farm during the planting season of 2005 - 2006. The results of the study can be summed up in the following : 1. The results showed that the sample of Soils polluted with Oil residues resulted in redacting in the growth speed with the concentration 12000ppm, lowest rate was 63.41% in the class Iraq and 45.37% in the class Amal,whereas samples of Soil polluted with low concentration resulted in significant increasing reached 10.73% in class Amal, when compared with the control treatment. 2. The results showed a decreasing in certain features of the plants such as plant length, number of leaves, number of offshoots, the weight of dry plants and the weight of dry roots in the polluted soils with the concentration of 8000 and 12000 ppm, whereas the concentration 4000ppm shows proximity or increasing in the rate of these features compared with the control treatment.3. The polluted soils with high concentration of 8000 and 12000ppm affected negatively the productivity of wheat and barley on (length of ear, number of grains/ an ear of 100 grains) whereas a significant increasing, compared with control treatment, in Soils polluted with the concentration of 4000ppm.4. A reduction in the amount of chlorophyll a, chlorophyll b and total chlorophyll (a+b) in the soils polluted with High concentration of Oil residues, and an increasing or no significant difference with the control treatment in the Soils with low concentration 4000ppm.5. A reduction in the amount of Carbohydrates was happened in the green parts of both species, Barley and wheat, in the Soil polluted with high concentration of oil residues reached 41.64% in class Tamooz - 2 and 46.72% in class Amal, whereas there was approximate with control treatment happened in samples of Soil polluted with low con.4000 ppm but no Seeds where produced in the concentration 12000 ppm, no Seeds where produced in both concentration 8000,12000 ppm of barley.6. The Soil polluted with Oil residues resulted in an increasing in the accumulation of certain ions of heavy elements and minor elements (lead, copper and zinc) in the Soil by increasing the concentration of oil residues and the movement of the ions of these elements into the plats and their accumulation in the different parts of these plants and its found that the concentration of these ions in the roots is higher than that in green parts and seeds.7. washing treatment of Soil polluted with oil residues resulted in a reduction of pollutant concentration in the Soil. Gradient of removing rate had the following arrangement : sandy, clay, and muddy soil, according to the following rates(87,72,48) respectively.8. washing the Soil reduced the negative effects of Oil residues during the positive role improving rate of Seeds germination, High Speed of germination was(1.35) in the clay Soil

المستخلص: تم دراسة الظروف الطبيعية الموجودة في القاعات الانتاجية لمصنع ادوية سامراء من خلال العوامل البيئية التي شملت الحرارة، والرطوبة النسبية. وشدة الاضاءة واعداد حجم الدقائق العالقة في الهواء وتاثيرها على الاحياء المجهرية الموجودة في القاعات الانتاجية حيث تم اخذ | The natural environmental conditions existing in the production units of Sammara drug company have been studied. Environmental factors included, temperature, relative humidity, light intensity as well as number and size of suspended particles in the air. From December 2006 through June 2007. 87 sampling visit was made during which 384 swabs were collected from three production buildings : Ibn - Hayan, Ibn - Sina and Al - Zahrawy. Results showed that at different temperature levels during this study dominance of bacterial colony over fungal colony in two buildings Ibn - Hayan and Ibn - Sina, was observed, whereas the dominance of fungal colony over bacterial colony in Al - Zahrawy building was noticed. While the effect of relative humidity on microorganisms showed that in Ibn - Hayan building at low relative humidity (41 - 53%) the dominance of bacterial colony over fungal colony whereas the dominance of fungal colony on bacterial colony at relative humidity (53 - 62%). While in Ibn - Sina building bacterial colony dominante fungal colony except at high relative humidity (63 - 73%), where the fungal colony dominance. The same pattern have shown in Al - Zahrawy building at low relative humidity less than 51% while fungal colony exceeded bacterial colony at high relative Humidity. Result of the effect of light intensity showed that the low light intensity have greater effect on fungal colony than bacterial colony this clear in Ibn - Hayan and Ibn - Sina buildings whereas increases in light intensity showed the reverse while the low light intensity in Al - Zahrawy building shown different effects which the dominance of fungal colony over bacterial colony. This perhaps reflects the different species of fungal colony in production units.The effect of the number and the size of 0.3 micron of particulates on bacterial and fungal colony was also examined. It has been noticed that the dominance of bacterial colony over fungal colony until the number of particulates 49000/foot3 in Ibn - Hayan building, while fungal colony appeared in most swabs in Ibn - sina building, but dominancy for bacterial colony. While in Al - Zahrawy building the swabs showed clear appearance for fungal colony, but some swabs shown high bacterial growth. The effect of 0.5 micron particulates showed that the dominance of bacterial colony with increased number of particulates in Ibn - Hayan building. The same pattern was shown in Ibn - Sina building, while in Al - Zahrawy building it has been the dominances of bacterial colony until 15000/foot3, but with increase in number fungal colony appear very clear. The following bacteria and fungi were identified during the course of this study; Staphylococcus, E.coli and a low genera of fungi like Penicillium, Aspergillus, Mucor. It has been shown by the collected swabs that the contamination with bacteria and fungi of drug production units never exceeded the standard limits set by the company except in very rare occasions the high contamination rate occurred in the hands of workers and delivery boxes in Ibn - Sina building.

المستخلص: تضمن البحث الحالي دراسة مقارنة مظهرية وتشريحية وكيميائية ووراثية لثمانية انواع تابعة للجنس Heliotropium L. (Boraginaceae) في وسط وشمال العراق هي H.bacciferum Forssk., H.ellipticum Ledeb. H.europaeum L., H.lasiocarpium Fisch., H.noeanum Boiss., H.ramosissi | The current research study is a comparative morphological, anatomical, chemical, genetical of the genus Heliotropium in mid and north of Iraq between eight species belonging to the genus of the family Boraginaceae, and the study included some morphological characteristic of the roots, stems, leaves, flowers (calyx, corolla, stamens, pistils), inflorescence, fruits and pollen grain shows that there are clear differences between the species under study. The study included aspects of anatomy and the differences included the qualities of epidermis leaf and stem and stomata as well as study transverse sections of roots, stems, leaves and petiole and peduncle, fruits, Nutlets and seeds, also studied the system of Venation in the leaf where he studied the type of venation as well as study the direction of midrib, thickness, branching as well as the study of secondary veins, Arrangement, Aerioles and Veinlets that showed clear differences between species.The study showed that pollen grains in the species are Tricolporate in all species except H.bacciferum it contains four grooves and pollen grains of contain Psaudotricolporate found in all species except H.lasiocarpium was completely absent of false grooves have distinguished this species by this character, showed the study of pollen grain Psaudotetracolporate in species H.bacciferum only and did not appear in the rest of the species. the study noted that there are variations evident in the two axes equatorial and polar as well as in the length of the groove, width, the rate of the thickness of the wall of pollen grain, the rate of diameter germination aperture in all species. The study showed clear difference between species in dimensions of upper and lower epidermis leaf, as well as a study stomata index on the surfaces of upper and lower leaves where show that all species were the lower surface more than the upper surface in density of stomata and Trichomes were studied in all parts of plants under study it was observed that there is variation in the distribution of hair and their locations as well as the lengths of hairs and thickness of the walls and shape of apex and base. Studied species in pathway of photosynthesis showed that two species are C4 plants H.noeanum, H.suaveolens either species H.bacciferum, H.ramosissimum, H.lasiocarpium was belong of intermediate C3 - C4 species while the rest were from C3 plants after analysis qualities and similarities of these qualities were very important to isolate the species from each other because present of bundle sheath, thickness of leave in cross section, thickness of cuticle, thickness of chlorenchyma and collenchymas tissues, frequency of stomata and it distribution, the number of aerioles and veinlets density and size. Has also been studying the chemical content of alkaloids and found that there are six alkaloids isolated for the first time from inflorescences for plants belonging to the genus Heliotropium were isolated using the technique liquid chromatography for identified six alkaloids compounds (indicine and supinine, indicine - N - oxide, heleurine, heliotrine and lindelofidine), which included the study of compounds Alkaliods type, concentration and percentage and the pyrrolizidine alkaloids that have a biological importance of cure tumors and cancers. The study showed high percentage of heliotrine in four species of Heliotropium H.bacciferum, H.ramosissimum, H.europaeum, H.noeanum were (48%, 54%, 51%, 54%) while heleurine was high percentage in two species H.suaveolens, H.supinum were (33%, 56%), while the study showed lower percentage of indicine - N - oxide in three species H.ramosissimum, H.noeanum, H.supinum were (2%, 4%, 1%). The current research identified for the first time on the content of the Glycosides from inflorescences in eight species of Heliotropium from mid and north of Iraq. These species are H.bacciferum, H.ellipticum H.europaeum, H.lasiocarpium, H.noeanum, H.ramosissimum, H.suaveolens, H.supinum by using the liquid phase chromatography diagnosis of six compounds (heliotrope, isopyrrolidine, isorhamnetin, naringenin, quercetein, triterpene) results showed that plant species studied vary their content of these compounds, with absent of naringenin in the species H.noeanum while absent of triterpene in species H.ellipticum, H.europaeum, H.supinum. They also showed the studied differences in concentrations glycosides and percentage of species as shown H.europaeum, H.lasiocarpium, H.noeanum, H.ramosissimum, H.supinum, H.suaveolens lower concentrations (12 - 37 mg / ml) and percentages (1 - 9%) for quercetein compared to the rest of the species studied and the species H.europaeum, H.lasiocarpium, H.noeanum, , H.supinum, H.suaveolens were higher concentrations (99 - 442 mg / ml) and percentages (26 - 51 %) for heliotrope compared to other species. These results indicate the possibility of the adoption of the content glycosides for inflorescence criterion for the separation between species as well as use for medical purposes, especially pyrolizidine and isopyrrolidine important in the treatment of tumors and cancer. Studied the genetic variation through the study of random variation indicators RAPD for eight species of the genus Heliotropium, and using 14 primer showed variation between the species under study and were divided into two groups are : 1. Group A : Included only two species H.bacciferum, H.ramosissimum where the genetic distance between these two species (0.249) where the two species are similar in genetic traits and genetic content in the absence of many bands of the primers and appear in the other. 2. Group B : Included six species of the genus Heliotropium under study and was less genetic distance between H.ellipticum, H.europaeum where (0.105) and this is a great similarity in appearance bands between the two species in some of primers, then the following two species were also two other, where he was the closest genetic distance between the two species H.lasiocarpium, H.noeanum where (0.153) and was very close two species of H.ellipticum, H.europaeum were was (0.125). The data were analyzed and characteristics after into the program (NTSYSpc) to study morphological and anatomical, chemical, genetic and find a genetic distance inter - species on the basis of similarity So was isolated species to groups and based on a large number of morphological characteristics and anatomical, chemical, genetic possible distinguish species from each other and show the variation at the level of species belonging to the genus Heliotropium.

The experiments had been performed in the animal house at Dept.of Biology of Education Fecundity at Tikrit Univ. from Jan. 2011 through July 2011. male rats were measured (250 - 350)gram, in age (16 - 20) weeks, (110) experimental, the rats were divided to (22) groups in which each consisted of (5) rats.The first experiment results have revealed the following : - 1 - The giving of Ferro alone and the Second dose has caused a noticed significant increase at the level of (p<0.01) in the total number of white blood cells (WBCs) and in the concentrations of each of Glucose(Glu), Total cholesterol (TC), Triglyceride (TG), Low density of lipoprotein - cholesterol (LDL - C), (VLDL - C), Malondialdehyde(MDA)and Peroxy nitrite(ONOO.) compared with control group, whereas it caused a high significant decrease at the level of (p< 0.01) in the concentration of each of High Density of lipoprotein of cholesterol(HDL - C), Total protein (TP), Glutathione(GSH) and ceruloplasmin(CP) and a decrease in sperm parameters. The two groups have also noticed a significant decrease of (p<0.01) in the concentrations of the melatonin hormone in the rats blood serum, growth Hormone and the Luteinizing hormone, in addition to the testosterone hormone and a decrease in the effectiveness of the catalase enzyme; taking into consideration the accumulative increase of Ferro element in the liver, kidneys and testes for both groups. As for the accumulation of copper, it has been noticed in the second dose group in liver, kidneys, and testes tissues, whereas the group of animals exposed to Ferro alone has noticed a high significant decrease in copper concentration in the three studied organs.2 - The giving of a first dose to white male rats (rattus ratus) has revealed a lack of significant differences in each of the total number of white blood cells, and the concentrations of most of biochemical parameters and sperm parameters, taking into consideration the significant decrease in the concentrations of each of (HDL - C), (GSH), (CP), (Mel), and (CAT). It has been noticed the occurrence of a significant increase in the concentration of (LDL - C). This group has also suffered a significant and insignificant increase in the Ferro accumulation in the studied organs, with a simple decrease of the accumulation of copper element in the three studied elements compared to the sound control group.3 - The giving of the three vegetal extracts which are Punica granatum L., Comellia sinensis L., and Olea europaea L. for animals exposed to second dose has caused a high significant decrease (p< 0.01). The effective power of extracts according to their arrangement and order in which first is Olea europaea L., then Punica granatum L., and lastly is Camellia sinensis L. have revealed positive significant changing in many biochemical parameters, with high significant increasing in (Mel), (GH), (LH), and (T) blood serum conc. in addition to the effectiveness of (CAT), compared to the group of animals exposed to second dose. All the sperm parameters in each of Olea europaea L. and Punica granatum L. have revealed a significant increase compared to the second dose group, whereas the Comellia sinensis L. has not revealed the occurrence of significant changes in most of the sperm parameters except in the percentage of active and moving sperms when compared with the second dose group.As for the accumulation of mineral elements, all the groups treated with vegetal extracts and exposed to second dose have witnessed a decrease in the accumulation of Ferro element in the liver, kidneys and testes tissues when compared with the second dose group, and this is also a fact concerning the accumulation of copper element.4 - The giving of Ferro alone and second dose have caused clear malady and tissue changes represented by diffusion of fat drops in a wide range between the liver cells. There has also been a poisonous and harmful effect of kidney tissue represented by the harm occurring in the disintegration and damage of the glomerulus and damage to the renal tubules, on the level of testis tissue, there have occurred huge damages in most tissue structures of the testes with a loss of most of the sperm formation stages, whereas the first dose group has not revealed any clear tissue changes compared to the sound control group. These changes have decreased when treated with vegetal extracts for each of Punica grantum L., Olea europaea L. and Comellia sinensis L. with the availability of Ferro and copper elements, since these elements have largely decreased the negative effects by affecting the three tissue levels which are liver, kidney and testes. Olea europaea L. has revealed a magnificent role on the reformative level of damaged tissues with a big similarity to the control group which exceeded both of Punica granatum L. and Comellia sinensis L. compared to the second dose group.Second experiment results : - 1 - The treatment of animals with hydrogen peroxide revealed very high significant changes at the level of (p<0.01), (p<0.05) in white blood cells, and in most of the biochemical and hormone criteria and sperm parameters which are similar to the effect of each of the Ferro dose alone and the second dose when compared with the sound control group.2 - The treatment of animals exposed to oxidative stress via hydrogen peroxide with Capsicum annuum L. and Musa paradisiacal L. separately Shown positive effect more than Prunus cersus L. and Prunus avium L. all juice led to the occurrence of noticed significant decrease at the level of (p<0.01) in the total number of white blood cells and in the concentrations of (Glu), (TC), (TG), (LDL - C), (VLDL - C), (MAD) and the root (ONOO.). This is compared with the group exposed to hydrogen peroxide alone, taking into consideration the occurrence of high significant increase in the concentrations of (HDL - C), (TP), (GSH), (CP) and in sperm parameters. There has also been noticed a significant increase in (p<0.01) in the concentrations of each of (Mel), (GH), (T) and (CAT)and (LH) compared to the group exposed to hydrogen peroxide alone.3 - The treatment with industrial tryptophan did not reveal any changes in the total number of most of the studied biochemical and hormone concentrations, but there has been witnessed an occurrence of significant decrease in the concentration of (LDL - C). As for the sperm parameters, the changes were between significant decrease and no significant changes when compared with the control group, with a significant increase in the effectiveness of enzyme CAT and concentration of hormone (Mel) in blood plasma with the sound control group.4 - The exposition of male rats (rattus ratus) to a period of continuous lightness led to the occurrence of several physiological and biochemical changes and to a high significant increase of (p<0.01) in sperm parameters and in the concentrations of hormones (Mel), (GH), (T), and (CAT) in blood plasma when compared with the control group; except for the occurrence of high significant increase in concentration of (LH). The darkness group revealed slight insignificant changes in most of the biochemical criteria and between the lack of changes in concentrations of (GH), hormone (T) and enzyme (CAT). This group also suffered the occurrence of high significant increase in concentration of (Mel) and a significant decrease in concentration of hormone (LH) when compared to the control group.5 - The giving (H2O2)caused several tissue changes in the livers of male rats (Rattus ratus). This has caused clear tissue and malady changes and similar to the Ferro and second dose groups. These changes have reduced when treated with Prunus cersus L., Prunus avium L., Capsicum annuum L. and Musa paradisiacal L. with the presence of hydrogen peroxide in that it greatly reduced the negative effects of hydrogen peroxide on the level of the three tissues of liver, kidney and testes. There is a lack of harmful tissue effects of industrial tryptophan on the tissues under study, when compared with the control group. In addition, both groups of rats exposed to durations of continuous lightness and darkness have suffered very huge tissue damage on the level of the three tissues, but the continuous lightness group suffered more damage when compared with the control group and continuous darkness duration.

The current study was designed for research purposes to detected some of Biochemical , hematological and histological variables which have direct relationship with oxidative stress among studied sample to determine the effect of this variables on aborted women in Kirkuk province. The study found that : 1 - There was a continues increasing in the number of abortion between the year 2010 - 2011. 2 - Many causes were related to abortion occurrence which arranged according to their importance as follow : Hormonal. Infective, Congenital, parasitic. 3 - Villi dimension (width and length) measures less than those of 1st control group (normal vaginally delivered women).4 - Placental weight (wt) taken from aborted women measure less than those taken normal delivered group (1st control group).5 - From the study results, it was indicated that the total body mass index (BMI) among aborted women recorded less significant value (p< 0.05) than those of 1st control group and high significant value in comparison to the 2nd control group (new pregnant women 6 - The current study show that the consented level of malondialdehyde(MDA) in blood serum among aborted women is higher than those of 1stcontrol group and 2nd control group. Also it was indicated that the level of MDA in placental extracted is higher than 1stcontrol group.7 - Regarding Glutathione concentration, the aborted women recorded significant elevation in level of blood serum in comparison to the two mentioned control groups, also its concentration in placental extract is higher than 1st control group only.8 - The study found that the level of glutathione peroxidase GPX concentration is significant decrease among aborted women in comparison to the 1st control group while the level of peroxy nitrate PN was a significantly increase in its concentration in blood serum.9 - The current study revealed that there is now a significant in albumin conc. And uric acid in blood serum among aborted women in comparison to2nd control group.10 - The study referred to the significant different value (p<0.05) in concentration of estrogen hormone in blood serum among aborted women which indicated that there is a low conc. also progesterone hormone level recorded less than in the women in comparison both control groups.11 - The study found that the Concentration of Tri - iodothyronine hormone which recorded is a low in aborted women comparison both control group while thyroxin hormone referred to the a significantly decreased in blood serum comparison to 1st control group and now significant comparison to 2nd control group.12 - Concerning the prolactin hormone level which recorded alow conc. Level among aborted women.13 - Blood pressure recorded a significant decrease in both tow measures (systolic and diastolic).14 - Hemoglobin (Hb) and red blood cells (R.B.C) recorded a significant decrease in its value among aborted women and a significantly elevation in white blood cells level(W.B.C)in comparison to both control groups.15 - Toxoplasmosis antibodies were detected in 10% of aborted women.16 - Histological studies, Histological study revealed that there is an obvious cross - sectional placental changes among studied women. The study show that there is a large amount of Red Blood Cells (R.B.C.) in placental section among women subjected to previous complete abortion which indicates a sever hemorrhage, the RBC seen collected in some area of referring to degeneration and hemolysis process with the presence of small piece of uteri in the tissue epithelium distributed between red blood cells due to while in women subjected to spontaneous abortion, the histological appearance enlarge and small pieces of uterine tissue epithelium distributed blood vessels which indicated that is an aggregation of RBC and seen of the nuclei appear atrophied in there is a presence of double size degradation nuclei and hemolysis of muscle nuclei which presented either spindle or flat in shape.In women subjected to incomplete abortion, the histological section a show the of uterine lying cells with muscle cells and bleeding due to rupture of placental blood vessels with hemolysis of red blood cell which appear like clusters duo to congestion process and the muscular layer appears clear fibers, necrosis.It is also obvious that in those women who subjected to in complete abortion, there is a large amount of falling muscle tissue with abortion process which is a thin structure with little necrosis in some area of it hamolysis can be seen presented by R.B.C decomposition and swelling of uterine lying nuclei and necrosis which the chromatin bodies appear either as spare parts or atrophied for the final analysis with the other appeared empty and necrolizal due to ruptured uterine lying epithelium and hemolysis is of R.B.C

The study showed that the rate of infection with E. histolytica / E. dispar was 21.67% (130 of 600). The cystic stages were dominant in infected stool samples which being 53.85% (70 of 130), while the trophozoite stage was 15.38 % (20 of 130). The epidemiological survey based on direct stool examination showed the rate of infection among females was 23.07% (60 of 260) in comparison with males 20.59% (70 of 340). The highest rate of infection was among the age group 1 - 5 years 25.5% (69 of 270). The highest rate was also in children of illiterate parents 26.1% (68 of 260). The biochemical tests were carried out to estimate serum cholesterol, triglycerides, GOT, GPT, malondialdehyde (MDA) and selenium. The study showed that the level of serum cholesterol, triglycerides, GOT, GPT, malondialdehyde increased in infected patients in comparison with healthy controls, while the study showed decreased selenium concentration in infected patients in comparison with healthy controls. The enzyme linked immunosorbent assay(ELISA) was done to estimate serum IgG level for Entamoeba histolytica, the rate of seropositivity for IgG was 21.68% (18 of 83). The rate of IgG in positive sample was 17.73% (7 of 41) while in negative sample was 26.19% (11 of 42).
