Abstract: اجريت الدراسة الحالية لغرض التحري عن وجود الجينات الكروموسومية المسؤولة عن بعض عوامل الضراوة المهمة لجنس Pseudomonas aeruginosa كانتاجها للسم الخارجي A والالجنيت اضافة الى الجينات الكروموسومية المسببة لمقاومة الكوينولونات في العزلات السريرية والبيئية لبكت | This study include investigate the presence of chromosomal quinolone resistance genes and virulence genes(toxA and algD) in clinical and environmental isolates from Al - Sadr Medical city.A total of 110 samples were collected from different clinical sources(burns, wounds, and urine), and 50 from the hospital environment.the samples were collected during 10, Oct, 2012 to 2, Feb, 2013. A total number of Pseudomonas aeruginosa isolates accounted for 89 of 160 samples.The distribution of these isolates were 28 from Burns, 14 wounds, 15 urine, and 32 from hospital environments. Identification of isolates has been accomplished depending on phenotypic diagnostic methods and PCR technique.our study proved that PCR technique depending on oprI and oprL genes was a rapid method for identification of non - pigmented isolates. A total of 20 antibiotics resistant isolates were chosen for Molecular studies. The result reveling that 100% of isolates had a chromosomal mutation in the QRDRs of genes (gyrA, gyrB, parC, and parE). High percentage of isolates(45%) carried mutated genes gyrA and parC, followed by 15% of isolates were carried either mutated gene gyrA alone or three mutated genes gyrA, parC, and parE and and 10%of isolates were carried three muted genes gyrA, gyrB, and parC, while gene that encoding to parC mutation were detected in 5% of isolates. Our study is the first study about detection of Quinolone Resistance Determining Regions in P.aeruginosa in Iraq. The results showed the the presence of mexAB - oprM multidrugs efflux system expression in 100%(20) isolates. while the phenotypic test depending on MIC values for ciprofloxacin alone in the presence of efflux inhibitor showed that only 15%(3) isolates had the active efflux pump.

Abstract: هدفت الدراسة الحالية الى تقييم النسبة المئوية لكروماتين النطفة غير السوي Abnormal sperm chromatin percentage لمرضى عديمي الخصوبة مقارنة بالرجال الخصبين ودراسة العلاقة بين النسبة المئوية لكروماتين النطفة غير السوي ومعايير المني ومؤشر نوعية النطف وتركيز الم | The aim of the current study was to evaluate the Abnormal sperm chromatin percent for the infertile comparing with the fertile men and study the relation between the Abnormal sperm chromatin percent, the sperm and semen parameters, sperm quality index and MDA concentration for the infertile normozoospermic and asthenozoospermic patients comparing with the fertile men.This study was conducted in the laboratories of fertility centers in Al - Sader medical city/ Al - Najaf Al - Ashraf from 1 / 11 / 2012 to 30 / 4 / 2013.By the end of the semen liquefaction time, the 72 samples were divided into two groups : - the fertile men, (17), and the second is represented by the Infertile Normozoospermic (23) and the Asthenozoospermic (32). The age average was (1.36±30.9) , (0.98 ±29.6) and (1.63± 31.4) years respectively. The samples were restricted to the non smoking patients only. The study results show a significant (P< 0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the sperm viability percent and the semen volume, and a significant (P<0.05) increase in the round cell concentration, liquefaction time, Malondialdehyde concentration and the percent of the abnormal chromatin of the Normozoospermic and the Asthenozoospermic patients comparing with the fertile men. The results also show a negative correlation (P<0.05) between the (MDA) concentration and the parameters represented by the sperm concentration, percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent sperm quality index and semen volume. While it had been noticed that there was a positive relation between the MDA concentration and the parameters represented by the sperm liquefaction time, round cell concentration and the abnormal sperm chromatin percent of all the study groups. In this research the relation between the sperm chromatin damage and the other study parameters had been studied by dividing the samples according to the degree of chromatin damage. The results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent, the sperm quality index and semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration (MDA) concentration and the percent of the abnormal chromatin of the group (> 10) comparing with the group (? 10) for the fertile men, also the results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent and the semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration for the group (> 25) comparing with the group (? 25) for the infertile Normozoospermic patients. For the Asthenozoospermic patients the study shows a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm quality index, the sperm viability percent and semen volume, and a significant (P<0.05) increase in the liquefaction time and round cell concentration for the study groups represented by the group (> 20 - 40) and (< 40) comparing with (? 20). From the above results it could be concluded that the increase of (MDA) level resulted from the active (ROS) leads to an increase in the abnormal chromatin percent of the infertile Normozoospermic patients which had a negative effect on the semen parameters which could be a reason for the infertility for those patients

Abstract: يعد السرطان واحدا من المخاطر الاساسية التي تهدد حياة الانسان في مختلف بلدان العالم، لان هذا المرض لا يقف عند عضو معين فهو ينتشر الى كثير من اعضاء الجسم الاخرى ليفتك بها، ومن هذا انطلقت الدراسة الحالية التي اجـريت للفترة من تشرين الاول / 2012 م ولغاية اب | The Cancer is one of highly risk factors that threats the human life world wide, because the disease has metastatic property from primary to secondary sites. This study was carried out during the period extending between October 2012 and August 2013, in laboratories of Faculty of Veterinary Medicine & Faculty of Education for girls in University of Kufa. It is aimed to follow up the changes in volume of growing tumor in female albino mice which were injected with cells of murine mammary adenocarcinoma.The histological changes, immunohistochemical examination investigate the distribution of CD8+ T lymphocytes were also studied.The changes of IgG and IgM titers in serum were also investigated. The study included use of 40 female albino mice at age 6 - 8 weeks, 25g weight average.All mice were injected by cells of murine mammary adenocarcinoman (AM3) in subcutaneous of femoro - dorsal region, and ascending to cervical region. The tumor was successfully implanted into 28 mice.These mice divided into four groups, each contains seven tumor - bearing mice.The animals of the first group subjected to the investigations after 48 hrs from implantation , while those of 2nd, 3rd & 4th groups after 10, 20, 30 days respectively. Seven healthy mice were considered as control group to comparison of immunological tests. Tumor volume & relative tumor volume were measured in different experimental groups. Histological section were prepared by routine histological techniques that including the steps of dehydration, clearing, infiltration, embedding, cutting & staining by hematoxylin and eosin stains, then microscopical examination had been done by optic microscop. The results indicated there was significant increase in tumor volume and relative volume with advancing of tumor age in animals of 2nd, 3rd & 4th groups where compared with first group. The gross examination of the animals of different groups showed that the tumor grew as irregular projection with loss of hair and erosion of overlying skin with milky discharge. The post - mortem examination revealed that the tumor mass was divided into small lobules with various coloures and the tumor mass surrounded by fibrous tissue which increase in thickness as the tumor increased in the age. Extensive areas of necrosis were noticed in the centers of the tumor masses. The microscopic examination of tumor masses in the first group raveled there were sub cataneous small aggregation of tumor cells at the implantation region as well as dispersion of the implantated tumor cells. The inflammatory cells, especially neutrophils were infiltrated. In the second group, the tumor masses showed lobulation by fibrous septa with proliferation of new blood vessels with congestion of them. Infiltaration of inflammatory cells, particularly the lymphocytes. The tumor cells arranged as ribbons and acini, characterized by hyperchromacia pleomorphism, high N/C ratio as well as appearance of mitotic figures. The histological features of the third group revealed increase of amount of fibrous tissue extensive necrotic areas and loss of architecture.These appeared in the fourth group in addition to the presence of cellular debris with dead inflammatory cells. The immunohistochemical study showed no CD8+ T cells were infiltrated in the mass of first group but the little infiltration of these cells was show in the second group. The highest infiltration of the CD8+ T cells was appeared in the third group. while the little cells were discharged in the fourth group. The results of the single radial immunodiffussion assay showed that the implantation with mammary adenocarcinoma had significant effect in increasing the titer of IgM after (48) hours and (30) days from implantation of tumor compared to control group, while the titer is not significant after (10) and (20) days from implantation of the tumor compared to control group. Also the results revealed a significant decrease in the titer of IgG after (48) hours and (30) days from implantation of the tumor, while were no significant increase in the titer of immunoglobulin after (10) and (20) days from implantation of the tumor, compared to the control group. From all the above, We concluded that there was variable histological changes as the age of tumor advanced these changes were characterized by increase of amount of tumor cells in the first groups and occurrence of necrosis in late groups, as well as increase the fibrous tissue as the tumor age advanced. The infiltrative CD+8 lymphocyt was also variable as change of tumor age. The implantation of tumor in mice groups had marked effect in stimulation of humoral immune response through increase of IgM & IgG titers.

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.
