The two experiments were conducted at the field of College of Agriculture/Al - Qadisiya University during the period from 31/10/2012 to 14/3/2013. For the field experiment, dry and fresh leaves of Eucalyptus were used at the rate of 0, 2, 3, or 6 g dry leaves/Kg soil or at the rate of 0, 4, 8, or 12g fresh leaves/kg soil. Plant height, changes in height during plant life time - course, number of branches, number of flowers, and flower diameter were measured. In addition, chlorophyll content in leaves, anthocyanin in petals, dry weight, nitrogen percent, potassium and phosphorous content in leaves were also determined. For the laboratory experiment, ethanol extract, oil, terpenes, alkaloid, and phenols extracted from Eucalyptus leaves at different concentrations were used. Seed germination, coefficient velocity of germination, plumule and radical length, sugar, protein, melanodialdehyde, glutathione and proline content were evaluated. The results were as follow : 1. Ethanolic extract was negatively affect the percent and coefficient velocity of germination in addition to plumule and radicle length. The reduction in these parameters was greater at the highest concentration of the extract, especially in Calendula officinalis. 2. Treatment with oil extracted from Eucalyptus leaves caused a significant reduction in percent and coefficient velocity of germination, plumule and radical length. 3. Terpenes, alkaloids or phenols treatments at different concentrations resulted in significant reduction in percent and coefficient velocity of germination, plumule and radical length. The reduction was increased as the concentration of the treatments increased. 4. Plant height decreased significantly due to the treatment with dry or fresh Eucalyptus leaves, the reduction in plant height increased as the concentration of the treatment increases in all plants except Asteriscus graveolens plant which showed that the small concentrations of both treatments. It was close to ward in an increase in plant height. 5. Number of branches also significantly decreased when ornamental plants treated with dry or fresh Eucalyptus leaves; the Calendula officinalis plant was the most affected. 6. For the changes in ornamental plants height, as a result of treatment with dry or fresh leaves of Eucalyptus, during life time - course, it was clear the growth curve was close to the S - shape growth curve with obvious significant differences for most treatments compare to control. 7. Dry weight percent was significantly affected in all ornamental plants when they treated with dry or fresh Eucalyptus leaves, If decreased with the concentration of the treatments increased. 8. It was obvious that treatment with dry or fresh Eucalyptus leaves resulted in significant reduction in flower number and flower diameter. Number of flowers decreased as the concentration of the treatments increased. on the other hand, flower was diameter increased as the concentration of the treatments increased, but in both cases it was less than the control. All one obvious that reducing significant in flower diameter, It was reducing great in low levels. 9. Chlorophyll content was also decreased in leaves, while anthocyanin content in petals was increased when the ornamental plants treated with dry or fresh Eucalyptus leaves. 10. Nirogen percent, phosphorus and potassium content in leaves of the four ornamentals decreased when they treated with dry or fresh Eucalyptus leaves. 11. Using terpenes, alkaloids and phenols caused significant increase in sugar content in leaves of the ornamentals, reaching its highest values at the highest concentration of the terpenes. For protein content, it was gradually decreased as the terpens, alkaloids and phenols concentrations increased in Calendula officinalis. In Tagetes patula, protein content was noticeably increased with the increasing in concentrations of the treatments. 12. Malondialdehyde, glutathione and proline content increased significantly in Calendula officinalis and Tagetes patula plants when they treated with terpenes, alkaloids or phenols. 13. Interaction between treatments concentrations and kind of plants had significant effect on all parameters measured.

المستخلص: يعد الاخصاب خارج الجسم الحي (IVF) من احد اهم التقنيات المستخدمة لانتاج اعداد كبيرة من الاجنة لبحوث التطور الاساسيه والبيولوجيا الجزيئية لنضوج البويضات المختبري والاخصاب. يعتمد الاخصاب خارج الجسم الحي وظروف حفظ الجنين المثلى على مكونات الوسط الزرعي كونها ا | In vitro fertilization (IVF) is one of the most important techniques used to produce large numbers of embryos for research into the basic development and molecular biology of in vitro oocytes maturation and fertilization. Optimal IVF and embryo culture conditions depend on the composition of culture media being the most important determinants of success in vitro interaction of the gametes and subsequent embryo development. Adenosine 5 - triphosphate (ATP) is a fundamental factor to maintain life, by providing energy, and controlling the cell function and metabolism. Objectives : The present study aims to investigate the effect of ATP supplied to SMART medium on a rate of fertilization and early embryonic development (ED) in mice as a model for human beings.Materials and Methods : The female mice (90) were superovulated using superovulation program to produce a large number of oocytes. These were divided into three groups, the first group was inseminated with vassal sperm in vitro alone (control); the seconed group (G2) was inseminated with vassal sperm in vitro using SMART medium enriched with low concentration of ATP(1.25mM). The third group (G3) was inseminated with vassal sperm in vitro using SMART medium enriched with high concentration of ATP (2.5mM). Mouse spermatozoa were collected from both vasdeferens. Then sperm parameters were assessed after 30 min. IVF technique was performed for 3 groups, and assessed after 20 - 22h. Then, percentages of early embryonic development stages and abnormal embryos morphology (%) for each embryo stage were assessed.Results : Results of the present study revealed significant increment (P<0.05) in the in - vitro fertilization (%) when using 1.25mM ATP as compared to 2.5 mM ATP and the control group. Significant differences (P<0.05) in the 1 - cell stage were assessed in 2.5mM compared with 1.25mM groups and the control group. Also, Significant differences (P<0.05) in the 2 - cell and 4 - cell stage were assessed in 1.25mM ATP compared with other groups. However, non significant differences in the percentages of abnormal embryos morphology were reported between both treated groups of ATP.Conclusion : From the results of present study it was concluded that the low ATP concentration (1.25mM) enriched to the culture medium improved the percentage of in vitro fertilization and early embryonic development.

المستخلص: The present study aimed to shed light on the identification a panel of genes with distinct expression patterns in breast cancer patients as a useful tool for breast cancer early detection and progression. The present study designed to investigate the levels of genes expression of five genes panel (MGB1, CK19, MUC1, miR - let7a, and miR - 195) in circulating free mRNA and miRNA from blood of breast cancer patients versus noncancerous samples (benign tumor and healthy controls) to establish a biomarker panel potentially useful for early detection and progression of disease. The expression patterns of the identified genes were then compared with certain clinical features (age, lymph node status, and tumour size).Blood samples from 55 patients with different stages of newly diagnosed invasive ductal carcinoma were provided by certain Iraqi hospitals. Two control groups were used in this study; 10 samples of patients with benign breast tumors, and 20 samples from healthy donors. The samples preservation with TRIzol was done. Samples subjected to total RNA extraction, and then molecular study by using reverse transcription and real time PCR at Molecular Oncology Unit in Guy´s Hospital - Kings College / London.The study reached the following results : 1. The patients’ age range was 24 - 70 years and the median was 49 years with high frequency of patients in the range of 40 - 59 years. According to the family history, 50(90.91%) of patients were have negative family history. According to the clincopathological features (lymph node status and tumor size) the percentages of patients with multiple lymph nodes and tumor size 2.0 - 2.9 cm were the highest groups, which showed statistically highsignificant differences.2. For MGB1 gene expression, the result showed that 30(54.5%) patients were MGB1 - positive while 25(45.4%) patients were MGB1 - negative.According to malignancy status the percentage of patients with high level of MGB1 gene expression 22(40%) was significantly high. In correlation with age groups there was statistically no significant differences in the levels of gene expression with age. In correlation with clincopathological features, lymph node status showed that the highest percentage of MGB1 positive patients 18(66%) were multiple for lymph node status, and the tumor size results showed that there was decreasing in the MGB1 geneexpression with increasing of tumor size. 3. For CK19 the results of present study showed that 41(74.54%) patients were CK19 - positive, while 14(25.46%) patients were CK19 - negative.According to malignancy status the percentage of patients with high level of CK19 gene expression 30(54.45%) was significantly higher in compare with benign tumor patients and healthy controls. In correlation with age groups there was statistically no significant differences in the levels of gene expression with age. In correlation to the clincopathological features, lymph node status results showed that the highest percentage of CK19 positive patients 24(88.89%) were multiple for lymph node status, and there was increasing in the CK19 gene expression with increasing of tumor size.4. Mucin 1 (MUC1) gene expression results showed that the percentage of MUC1 - positive breast cancer patients 72.73%(n=40) was significantly higher when compared with benign tumor patients and healthy controls. According to the age groups the results showed no significant correlation with patients age groups. The clincopathological features results showed that the highest percentage of MUC1 positive patients 84.21%(n=16) have few lymph node status, and there was statistically significant association between the increasing of MUC1 gene expression and tumor size. 5. The miR - 195 gene expression results showed that the percentage of patients with positive miR - 195 gene expression 83.64%(n=46) was significantly higher than patients with negative miR - 195 expression 16.36%, the study also showed that the percentage of high miR - 195 expression samples 69.09% (n = 38) was significantly higher in compare with benign tumor patients and healthy controls. According to the clincopathological features, patients with multiple and few lymph node metastasis were found to have significantly the highest percentages of miR - 195 expression, while the tumor size results showed that there was increasing in the miR - 195 gene expression with increasing of tumor size. 6. The percentage of miR - let 7a - positive breast cancer patients 81.82% was significantly higher, when compared with miR - let 7a - negative patients 18.18%. In correlation to the clincopathological features, results showed no significant correlation in miR - let7a gene expression levels with patients age groups, for lymph node status, the results showed that the highest percentages of let 7a positive patients were those with multiple lymph node and few lymph node metastasis. The tumor size results showed that there was increasing in miR - let 7a gene expression with increasing of tumor size.7. According to genes combinations, three genes combination (CK19, miR - 195 and miR - let 7a) was significantly positively expressed with percentage of 60%(33/55), which reflect their potential diagnostic and prognostic value.8. The study concluded that the three genes combination (CK19, miR - 195 and miR - let 7a) may have potential applications as a diagnostic and prognostic markers for breast cancer.

المستخلص: The study consists of three parts related with patients of CRC as in : 1 - Molecular part 2 - Cytogenetic and molecular genetics part and 3 - Immunological part. In addition of their relatives of clinical and pathological diagnosis, genus, and tumor locations in 150 of Iraqi patients confirmed with CRC collected from Teaching Hospitals of some Iraqi governorates. The percent of male to female (54.66% / 45.43%) and the aged range of study were 16 to 80 years.The first part consist a study of five types of genes related with CRC represented by MLH1, MSH2, APC, K ras, and SMAD7 genes. Some of these genes develop with germline mutations as in MLH 1 exons1 and 15 so as MSH2 genes. While the rest genes related with a sporadic of CRC. All these genes were amplified by conventional polymerase chain reaction (PCR) for study the types of the mutations and their defect of these genes on CRC. The APC exon11and K ras exon1 genes were processed by single strand conformational polymorphism (SSCP) technique. The results of PCR - SSCP technique for two genes represented by appeared three types of bands, which were (AA), (AB) and (AC) bands. The important band was (AB) which constitutes the variability region represented by 84.2% and 44.82% in patients for both genes. The results of patients with mutated bands with high significant differences(P?0.05).compared with healthy control. Patients carried these bands subjected to PCR - Sequences technique. The analysis results for APC gene sequences were substitutions mutations type of single nucleotide polymorphism (SNP) change Cytocine to Thiamin (C>T) at 1972 location of genome. While the analysis results of Kras gene appeared two types of mutations, substitution and frame shifts represented by deletion mutation and so as appeared stop codon mutation.The other genes represented by MLH1, MSH2, and SMAD detected by direct PCR - Sequences. The results analysis of MLH1 gene, exon (1and 15) represented by nucleotides change with high frequencies of substitution mutation through exon1 at different locations of nucleotides. So as frame shift mutation type deletion through exon15. While for MSH2 gene, exon 6 from 6.66% represent by deletion mutation. A spread study for SMAD7 gene, exon4 were done through 30 patients average age 52 years (male to female 56.7% : 53.3%) confirmed colorectal adenocarcinoma compared with 15 healthy. A mutation of 20% of (SNPs) were identified.The second part which represented standard conventional cytogenetic and molecular genetics were done through peripheral blood culture (PBC). The study showed increasing of mitotic index (MI) in patients with significant differences (P?0.05) compared with healthy controls indicating for increasing of proliferation of the lymphocytes division. The study showed some chromosomal aberrations with significant, the majority of aberrations were higher significant in dwarf and aneuploidy chromosomes so as elongation chromosomes revealed significant differences (P?0.05) between patients and healthy. The appeared of Polyploidy chromosomes, with significant differences (P?0.05), that’s seem to be good indicator for cancer disease. The molecular genetics alterations which dependent on cytogenetic investigation were done through deletion of long arm of 5 chromosome which APC gene is located. The test elucidates the importance of inactivation (deletion) of APC gene in elicited of colorectal cancer. The study of 20 patients, were investigated by fluorescent in situ hybridization (FISH). The results showed 60% patients which have 5q arm deletion of (+). And (5%) have two deletions (++) which was a male aged less than 60 years. The results analysis explained significant differences (p?0.01) between studied group and deletion (+) of arm 5q. A correlation represented by significant differences (p?0.01)through dysfunction of APC gene deletion of 5q were found with high percent among sporadic adenocarcinoma 58.3%, with less in attenuated familial adenomatous polyposis (AFAP) and familial adenomatous polyposis (FAP) represented by the (25%), and (16.7) respectively.The last part related with immunological test were done by detection of tumor markers represented by Carcino Embryonic Antigen (CEA), IL - 33 and IL - 31.These markers represented a confirmative indicators for colorectal adenocarcinoma which were tested by ELISA technique in (79) patients confirmed with CRC of male and female. These tumor markers in tested with patients showed high significant differences (p?0.01) compared with healthy controls. Another immunological test for detection of Human papilloma virus (HPV) type 18 E6 gene expression in CRC by Immune histochemistry technique (IHC) in 71 (FFPET) of CRC. The results of this study showed there were a correlations between patients and adenocarcinoma positive HPV18 E6 infection 43.7% of patients infected with virus, with high significant differences (p?0.01) and higher infection in female (67.7%) than male (32.3%). So as a correlations were found between HPV18 E6 expression and tumor tissue locations, explained by high percentage 45.2% in rectum.While a tumor marker was (CD8+) was used to determine its role in human immune surveillance in tumor regions of CRC so as with regions which were infected by HPV. The study revealed high significant differences between healthy control and studied groups which have (CD8+) positive infiltration in tumor origins through detection by (IHC).In conclusions diagnosis of CRC can be detected by special genes like K ras gene through professional PCR processing, compact with tumor markers, so as Fluorescent in situ hybridization (FISH) technique provides a precise method which can be used for detection of alteration of molecular and cytogenetic related with CRC.

The results of the phytochemical analysis of the crude aqueous and methanolic extracts of Myrtus communis, Mentha piperita and Ocimum basilicum contain active compounds : Phenols, Flavonoids and Tannins and missing of Steroids and Coumarines in all extract but Saponins and Alkaloids found in alcoholic extract only, while terpens were present in Mentha piperita and Ocimum basilicum and absent in Myrtus communis. The results of administrating animals with different extracts showed no significant difference on blood Acetylcholinesterase (AchE) compared with ethanol liquid diet, while the alcoholic and aqueous extracts of M. communis, M. piperita and O. basilicum in the serum of decreased Acetylcholinesterase level significantly(p?0.05), liver and brain [(1.25 ?pH/30 min, 1.23 ?pH/30 min, 1.28 ?pH/30 min, 1.20 ?pH/30 min, 1.26 ?pH/30 min, 1.28 ?pH/30 min), (0.35 ?pH/30 min, 0.34 ?pH/30 min, 0.34?pH/30 min, 0.36?pH/30 min, 0.42?pH/30 min, 0.39?pH/30 min), (0.32?pH/30 min, 0.37?pH/30 min, 0.39?pH/30 min, 0.36?pH/30 min, 0.34?pH/30 min, 0.37?pH/30 min)] respectively compared with animals fed on ethanol liquid diet [(1.37 ?pH/30 min), (0.47 ?pH/30 min), (0.45 ?pH/30 min)] respectively. The methanolic and aqueous extracts of M. communis, M. piperita and O. basilicum reported a significant decrease in level of the total cholesterol and Low Density Lipoprotein (LDL) [(181mg/dl, 186mg/dl, 175mg/dl, 172mg/dl, 181mg/dl, 184mg/dl), (118mg/dl, 121mg/dl, 114mg/dl, 109mg/dl, 118mg/dl and 120mg/dl)] respectively, when compared with animals fed on ethanol liquid diet [(195 mg/dl), (132mg/dl) ] respectively while no effect was reported on High Density lipoprotein. The level of triglyceride reduced after the treatment with ethanol liquid diet, and then the level increased after the treatment with M. communis and O. basilicum extracts. The methanolic and aqueous extracts of M. communis, M. piperita and O. basilicum have led to a reduction in the level of glucose in the serum which increased after the treatment with ethanol liquid diet. Methanolic and aqueous extracts decreased the liver enzymes (ALP, SGPT and SGOT) significantly to the normal level (18, 17, 21, 18, 20 and 21) KAU, (19, 19, 16, 13, 17, 17) IU/L and (21, 24, 17, 15, 17 and 19) IU/L respectively after the increase by the treatment with ethanol liquid diet (24) KAU, (26) IU/L, (28) IU/L as compared to control (20) KAU, (12.2) IU/L, (13.5) IU/L, respectively. The level of Interleukin - 2 and Interleukin - 4 in the serum significantly increased in the treatment of alcoholic and aqueous extract of M. communis, M. piperita and O. basilicum [(18 pg /ml, 17 pg /ml, 20 pg /ml, 18 pg /ml, 20 pg /ml, 20 pg /ml), (100 pg/ml, 110 pg/ml, 119 pg/ml, 108 pg/ml, 90 pg/ml, 92pg/ml)] in comparison with ethanol liquid diet treatment [(14 pg /ml), (77 pg/ml)] respectively. While the level of Interleukin - 6 and Interleukin - 10 increased significantly in the serum, when animals were fed with ethanol liquid diet [(259pg/ml) and (501pg/ml)] respectively, and then decreased significantly after the treatment of methanolic, aqueous extract of M. communis, M. piperita and O. basilicum reported [(198 pg/ml, 202pg/ml, 202pg/ml, 201pg/ml, 214pg/ml, 217pg/ml), (370 pg/ml, 385pg/ml, 200pg/ml, 280pg/ml, 350pg/ml and 350pg/ml)] respectively.

المستخلص: This study aimed to determine the frequency of Salmonella Typhimurium and its multi - drug resistance (MDR) status as a diarrheal causative pathogen in children younger than five years old, as well as to investigate the role of four probiotic microorganisms(L.acidophillus, L.casei, S.cerevisiae, S.boulardi) in controlling such infection.For this purpose, 128 stool samples of patients (76 males and 52 females) was included in this study. They were children suffering from diarrhea and fever who admitted to the “Central Pediatric Hospital” in Baghdad during the period from April to September, 2012. Their ages ranged from six days up to five years.The immunological effects of probiotics and MDR S. Typhimurium isolate in the experimentally infected and probiotic - treated mice were investigated via assessing the level of ten cytokines (IFN - ?, IL - 1?, IL - 4, IL - 10, IL - 12, IL - 17A, IL - 21, GM - CSF, RANTES and IP - 10) in the lavage of small intestine. Accordingly, five groups of mice were used in the in vivo part of this study; Mice in group I received probiotic for 7 successive days, challenged with S. Typhimurium on day 8, and dissected on days 14 and 21. Group II wassimilarly treated, but the probiotic was continued for 14 days. Group III was given the probiotic only, and group IV was challenged with S. Typhimurium, while group V was the control.Results obtained in this study could be summarized as follows : 1. Out of 128 stool samples, S. Typhimurium was isolated and identified in 9 samples only (7.03%). All isolates were totally resistant to nalidixic acid, with the exception of one isolate which showed intermediate sensitivity.Furthermore, only one of these isolates (symbolized B) was found to be resistant to three antibiotics (ampicillin, amoxicillin and nalidixic acid).Therefore, this isolate was considered as an MDR isolate and selected for further experiments in the study.2. When the susceptibility of MDR S. Typhimurium isolate B was further assessed in vitro by using four probiotics (Saccharomyces cerevisiae, S. boulardi, Lactobacillus acidophilus and L. casei), results showed that S.cerevisiae and L. acidophilus were the most efficient by recording the highest inhibition zones (12.6 and 16.3 mm, respectively), therefore, they were further investigated for their anti - S. Typhimurium effects in vitro and in vivo. 3. By using the unconcentrated and (one - fold, two - fold, three - fold) concentrated filtrates of these two probiotics, it was found that the three - fold filtrates were most efficient in their antibacterial activity by recording the highest inhibition zones (25.0 mm for S. cerevisiae and 31.0 mm for L. acidophilus.4. Significant increases in the values of liver index were observed in mice of group I treated with L. acidophilus at 21 days (10.73%) compared to the corresponding group treated with S. cerevisiae (7.41%) or other four groups. For spleen, index value in L. acidophilus groups was higher than the corresponding groups in S. cerevisiae. Mice treated with a probiotic alone or in a combination with the pathogen showed significant increases in the spleen index values of all groups compared to the untreated mice (group V).5. Both probiotics were effective in reducing S. Typhimurium colony forming units per plate (cfu/plate) in the liver and spleen. In liver, mice in group IV showed a count of 224.4 cfu/plate, which was significantly higher than any count in groups of L. acidophilus and S. cerevisiae. Group II mice recorded better results than group I mice, while the lowest counts (21.6 and 27.8 cfu/plate for L. acidophilus and S. cerevisiae, respectively), were observed at day 21.6. The ten investigated cytokines showed different levels in the small intestine wash; such differences were subjected to the group of mice underinvestigation and type of probiotics used. In addition, variations in IFN - ?/IL - 4, IFN - ?/IL - 10, IL - 4/IL - 10 and IL - 17A/IL - 10 were also observed.

المستخلص: Several air pollutant concentrations such as Suspended Particulate Matter (SPM), carbon oxides (COx), sulfur dioxide (SO2), nitrogen oxides (NOx), methane (CH4), ozone (O3) and some heavy metals such as lead (Pb) , chromium (Cr), cadmium (Cd), and nickel (Ni). Were measured in selected areas of the Rusafa in Baghdad, Anda’lus square (as a commercial site) and Wazeria district (as industrial site).The results showed that the concentration of air pollutants from gases, SPM (NO2, CO, SO2, and SPM) and heavy metals (Pb, Cr, Cd, and Ni) were exceeded globally and locally permissible limits in both study sites, while the concentration of O3, CO2 were within the globally and locally standard limits in both study sites. Commercial site had recorded higher concentrations of (CO2, SPM, Pb) than those of industrial site. While the industrial site had more pollution with (NO, NO2, CO, CH4, Cr). Results showed a relationship between climate factors and air pollutants, where windspeed, temperature, and relative humidity had influenced on the concentration of air pollutants.Median Lethal Concentration (LC50) to nitrogen dioxide gas was identified, by exposing a community of 30 adult male mice. The mice weights were between 23 - 31gm and their age was 8 - 12 weeks. The mice were randomly divided into five groups (6 male of each group). The exposure periods were 20, 40, 60, 80, 100 minutes using different concentrations 50, 100, 150, 200 ppm.The results showed a higher mortality during 150 and 200 ppm concentrations, for exposure periods of 80 and 100 minutes, but other concentrations have not been recorded. LC50 was calculated 161.86 ppm for 80 minutes and 110.53 ppm for 100 minutes.

Whereas three concentrations (20, 40 and 60) and (10, 15, 25) mg/l respectively for the two carp species were used in the chronic exposure for six weeks. The behavioral, histological and hematological changes were used as a standard to observe these effects through the study period. The value of LC50 for common carp fish were 157.77, 157.25, 156.41 and 152.62 mg/l. For grass carp, LC50 were 115.92, 114.92, 112.94 and 96.52 mg/l for 24, 48, 72, 96 hrs of exposure to 2, 4 - d pesticide concentrations respectively.Behavioral changes were recorded more effects in high concentrations than in low concentrations. To discover the toxic effects of this substance on fish, many parameters were used. They included the clinical symptoms by erratic swimming, hyperactivity, loss of equilibrium with respiratory effects such as rapid gill movement and swam near the water surface. While in chronic effects, blood parameters were changed in Red Blood Cell R.B.C., White Blood Cell W.B.C., Packed Cell Volume P.C.V., Haemoglobin Hb and liver enzyme (GPT & GOT).Values elevated significantly according to the pesticide concentration (P?0.001) and exposure periods (P?0.05) in comparison with control. The histological examination of the gills, liver and kidney of the common and grass carp fish after chronic exposure to 2, 4 - d herbicide showed pathological changes and alterations such as fusion of the secondary lamella, epithelial lifting, blood congestion, epithelial hypertrophy of the lamellar epithelium and epithelial necrosis. In the liver, pathological changes were seen, including hepatocytes hypertrophy, cytoplasmic vacuolation, blood congestion and cellular necrosis. Degenerative changes of the renal epithelium, necrosis in renal tubules and occlusion of the tubular lumen where the pathological alterations in the kidney.

المستخلص: من خلال البحوث والدراسات التي اجريت على اسباب وهن حركة النطف لدى الرجال الا انه هناك عدد من المسببات لم تحدد والى الوقت الحاضر. الا انه بالرغم من ذلك بعض الدراسات تشيربان العامل الوراثي يلعب دور في ذلك والمتمثل بعضيات المايتوكوندريا والحاوية على الدنا الم | Through researches and studies done on the causes of the asthenozoospermia in men, although there was no specific reason so far responsible for the infertility in people, but some of the studies were indicated that the genetic factors plays a role in the sperm dysmotility through the mitochondria that contained mitochondrial DNA responsible for providing the energy required for the sperm motility by production of ATP, which serve as the fuel that is consumed by sperm during motility. This study is conducted to determine the changes that could occur in the sperm mtDNA which included (common deletion, mtDNA copy number per cell and mutations in the ATPase8 and ATPase6 genes).This study was consisted of two parts as follow : The first part was consisted of two steps : The first step conducted on 71 samples from subjects suffering from the weakness of the movement of sperm and 12 samples from subjects who have a normal movement of sperm, total samples were 83 samples were divided patient samples into 5 groups depending on the percentage of the sperm motility under the classification adopted by the World Health Organization as well as a control group, that it has become 6 groups, these samples were subjected for investigation about the mitochondrial DNA deletions and mitochondrial DNA copy number by using real time PCR.On the other hand was taking 66 sample dispersed sample 56 patients and 10 healthy samples were subjected to the tests of ATPase6 and ATPase8 genes sequences for detection about mtDNA mutation.The second step was included the use of discontinuous gradient centrifugation (percoll) , which are 40 % and 80 % which represent both progressive and non progressive motile sperms, bringing the total samples 166 samples that collected and fractionated in a hospital, Kamal Al - Samarrai to treat infertility and IVF in Baghdad and examined for further molecular investigations for the period from February 2012 to October 2013.The second part was included the molecular tests that carried out after DNA extraction from the cells and this part include three steps : The first step was to investigate the common deletion in mtDNA where the results showed that the total number of deleted samples in the group (0 - 5) in the nonprogressive sperm was 81.25 %, which ranged between 6.8 - 74.7% while the ratio between the other groups 6 - 10, 11 - 15 , 16 - 20, 21 - 25 where were 75, 35.72, 28.5 , 36.3, and 12% for control group respectively. The second step was to investigate the sperm mtDNA copy number. The same groups where the results showed that the content of DNA in subjects with impaired movement of sperm was high compared with the control group where scored in some samples the highest level of gene expression 246.9 copies per cell in the group (0 - 5%) either other groups have shown lower levels were observed in groups (6 - 10) , (11 - 15) , (16 - 20) and (21 - 25) were 203.1, 180.7, 133.5 and 128.3 copies per cell, either the highest level of DNA content of the control group was 94.7 copies per cell, there was also a significant difference (P>0.05) between the normospermic motile isolated from 80% class and poor sperm movement isolated from 40 % class. The third step was included the detection of mutations by analyzing the sequences of the MT - ATAase8 and MT - ATPase6 genes which documented 59 mutations that were 23 missense and 36 silent mutations where all of them were heteroplasmic mutation except for a single mutation of the type missense (A8860G) which was homoplasmic mutation was noticed in all mtDNA copies of patients and control subjects also in progressive and non progressive sperm cells. Thought this current study novel nucleotides changes in MT - ATAase8 and MT - ATPase6 genes among groups where 3 novel missense mutations in MT - ATAase8 gene at positions (8378, 8483 and 8558), the changes of nucleotides bases were A>G, A>C, A>C and A>C respectively, replacing Asparagine to Aspartic acid, Leucine to Proline and Proline to Alanine respectively. Also two novel missense mutations were observed in MT - ATPase6 gene at positions nt (8822 and 9055) where the changes nucleotides were (C >T and G>A) that replaced amino acids (Serine to Phenylalanine and Alanine to Threonine) respectively. Silent novel heteroplasmic change as a transition substitutions in ATPase8 gene at position nt (8371) by replacing C>T without any changing in amino acid of protein. Results of this present study showed novel heteroplasmic silent mutations in ATPase6 gene at positions nt (8899, 9048 and 9060) nucleotides changes (C>T, T>C and C>A) respectively, without changing in amino acid of protein which were observed in infertile group

المستخلص: This study includes 82 clinical samples from male patients suspected to have gonorrhea (urethral discharge with dysuria). Two types of samples were collected from each patient, urethra swab and blood samples from patients who attended Al - Yarmouk teaching hospital in Baghdad city, Clinics and private laboratories during a period from December 2012 to April 2013. All of them were married and have children's, and 20 samples were taken from apparently healthy subjects.Cases caused by gonococci were diagnosed by finding the Neisseria gonorrhoeae bacteria in the samples using microscopic examination and culturing on rich media chocolate agare for growth bacteria and selective media modified Thayer martin agar (MTM) contact antibiotic to prevent growth of all the types of bacteria except N. gonorrhoeae.Microscopic examination using specific kit for gram stain, showed gram negative diplococcus, like bean shape. Culturing on rich media revealed that 82 (100%) samples positive but re culturing on Modified Thayer martin media revealed that 76 (92.68%) out of 82 positive. Then biochemical test had the same results.Results of the molecular diagnosis of the bacteria causing gonorrhea using specific primers that were specific for the Orf1 gene, revealed that 80.26% of samples (61 out of 76) were positive. Results of the microdeletion in Y chromosome AZFc region revealed that no microdeletion were occurred in SY - 254 STS and BPY - 2 gene.This study, provided high specificity and sensitivity for the diagnosis of gonorrhea using PCR technique which is cheaper and faster than traditional methods. Also, PCR - based method for detection of N.gonorrhoeae can be readily used in hospitals and laboratories.

المستخلص: This study has been conducted for the first time in Najaf / Iraq, and the study included the preparation of a local inactivated vaccine (whole and subunit).The number of cases infected with seasonal influenza virus were 647 cases out of one thousand suspected case. They were distributed into eleven groups. Seasonal influenza virus was detected by two diagnostic methods (rapid test device and real time PCR).The present study has reflected that the most diagnosed cases infected with seasonal influenza virus during the period extended from March 26, 2012 up to April 30, 2013 represented by were type A (H3N2) (283) cases. Whereas H1N1 (148) cases, H3N2+H1N1, (56) cases, H1N1 + H3N2 + B were (30) cases and 130 cases were infected with type B.Current study also revealed that age group of 46 - 60 years old infected with seasonal influenza virus were (159) case including (368) male and females were (279) of different infected group..The spread of seasonal influenza virus in Najaf varies from one region to another depending on the population density. Clinical cases were collected randomly during the months of the year. It has been found that the spread of disease has something to do with temperature and humidity as high humidity and low temperature lead to increased spread of the disease because of their relationship at the stage of the spread of epidemic influenza that spread from Dec 26, 2012 and up to April 1, 2013 in addition to expatriates infected..Two techniques were used for isolation of seasonal influenza virus first inoculation of embryonated chicken egg and secondly chicken fibroblast cell culture.It was found that at the embryonated egg lethal dosage (ELD 50 / 0.5 ml) (109.6) whereas tissue culture infective dosage (TCID50 / 0.1 ml) was (109.3) of (H1N1+ H3N2) and type (B) virus..Virus was purified by two ways that are depending on the vaccine type. The gamma irradiation that dosage used for inactivating vaccine of the purified virus which was extracted from allantoic fluid and tissue culture was (5.702) mSv/h for subunit virus vaccine type whereas gamma irradiation dosage for complete (whole) virus vaccine was (8.816) mSv/h. The results proved that immunoglobulins (IgM, IgA and IgG) levels as well as (IL - 17, IL - 10 and INF - 1?) indicated significant differences among vaccinated, infected and control groups.Subunit and whole virus vaccine extracted from chicken fibroblast cell culture are considered the best of derived from virus propagated in embryonated chicken eggs.Subunit virus vaccine is better than the whole virus vaccine derived from virus propagated in embryonated chicken eggs and extracted from chicken fibroblast cell culture.The current study also reflected that locally prepared virus subunit vaccine and purified whole virus killed vaccine capable of inducing humoral and cellular immune response in experimentally vaccinated rats..Histopathological changes appeared clearly on tissue sections (lung, trachea, heart, liver, spleen, kidney) of the infected group as compared with control and the vaccinated groups.

There was significant statistical difference between both groups as patients with MC had high level of IL18R1 than control.Themean±SD of IgMinpatients were 1946.6±825.6 mg/dlwhile in control were 140.1±68.7mg/dl This result was highly significant which indicates that patients with MC had higher level of IgM than control In contrast, patients had lower levels of IgG than control, The mean±SD of IgG in patientwere 221.9±96.7mg/dl while in control were 1229.9±299.7mg/dl. This result was highly significant. Also the patients had lower level of C3 and C4 than control. The mean±SD of C3 in patients were 109.6±64.8mg/dl while in control were 120.8±22.1mg/dl. The mean±SD of C4 in patients were 27.8±12.7mg/dl while in control were 38.7±9.8mg/dl. These results were statistically significant. Eleven 9 (14.7%) of patients had positive CRP while 12 (80%) of control had positive CRP which was statistically highly significant. Forty seven (62.7%) patients were from rural area while 28 (37.7%) from urban. There is no statistical difference between both groups as. Family history of MC and Recurrence of MC in patients were nostatically significant difference to infection by MCV.

Aim of the studyThe aim of the studyis to examin the possibility of using C - reactive protein in the early diagnosis of neonatal sepsis, as well as its use in determining thestop point of the antibiotic treatment.Patent, Materials and methods This study was conducted at the Hospital of Ibn - Albaladi for children and women in Rusafathe Healthoffice / Baghdad.Iraq from February 2013 to February 2014.The number of patients with bacterial infection was 102 (62%) of the total number of patients (165) who were admitted to the neonatal care unit aged less than 28 days and their weights was more than 1500 g,. The number of males was 92 (56%) and the number of females was 73 (44%), the number of patient withearly onset sepsis EOS (less than three days) was 43 (42%) and with late onset sepsis LOS for (more than three days) was 59 (58%), 43 (57%) ofEOSwas normal deliveries infected and cesarean deliveries infected 33 (43%), while51 (57%) of LOS was normal deliveries infected and cesarean deliveries in LOS was 38 (43%). Blood samples were collected and divided into three portion : bloodculture, CRP andhematological profile.1 - Blood culture.Blood was collection from neonatal sepsis patientinto special blood culture bottle and incubate in bact /Alert 3 D device when growth of bacteria then subcultured on blood agar, MaCconkey agar, and incubatedusingvitek /2 to diagnose bacterial infection anddeterminetheir susceptibility to antibiotic treatment.ResultThe Compact results indicated that 63 (38%)of patient were negative and 102 (62%) were positive out of them 23 patients (22.6%)were infected with gram negative bacteria including {Klebsiella pneumonia 30%, Acinetobacterlowffi 17%, Enterobacter cloaca 13%, } while 79 (77.4%) were infected with gram positive bacteria including { staph Homins and staph hemolyticus each 28% then staph epidermidis 13% and staph aureus 10%, while strep spp was 6% }. 2 - c - reactive protein.It was done by twomethod for the same samples in order to characterize the accuracy of the diagnosis. The first method was agglutination test (method 1) the cut off value for positive result ? 6 µg % 79 (48%)were negative, while 86 (52%) werepositive, while the second method was immune test (method 2) µµµusing Nycocard device werethe cut off value for positive result ? 5 µg % the results 102 (62%) were positive while 63 (38% negative.3 - hematological profile.The hematological profile of our patient included PCV, WBC, neutrophil, lymphocyte, monocyte, count were measured using Emerald automated Hematology device. The results of these tests werenot compatible with the results of the blood culture, but normal result were compatible with negative blood cultures. The results adopted of blood culture confirm the presence of bacterial infection and then compared with theresults CRP test and blood profilefor the same samples.Negative result of blood culture and CRP test were 54 (33%) while positive results of blood culture and CRP test were recorded and improved after taking treatment for (, 3, 5, 7,) days for (40, 31, 5)patients respectively.ConclusionWeconcluded C - reactive protein test was useful in the diagnosis of bacterial blood infections and determine the stop - point otreatment. Gram negative bacterial isolates were sensitive impinim, livofloxacin and Amikacin while they were resistant to Ampicillin, Ampicillin /Sollbectam and Gentamycin. on the other hand gram positive bacteria were sensitive to Amikacin, Ampicillin/sulbactam Ciprphloxacin, and Tigecyclin and were resistant to Erythromicin, and Oxacillinand Benzylpencillin.

المستخلص: المقوسات الكونديه من الطفيليات الشديده النجاح في انشاء اصابة مزمنه طويلة الامد. وقد اجريت الدراسة الحاليه على 366 امراة (117 مجهضات، 141 حوامل، 108 غير متزوجات) جمعت من مستشفيات مختلفة في بغداد. جمعت عينات الدم لجميع المجاميع المدروسة خلال الفترة مابين تش | Toxoplasma is a highly invasive parasite which establishes a life - long chronic infection. The present study was performed on 366 women (117 miscarriages, 141 pregnant and 108 singles) aged (17 - 35) years old from different hospital in Baghdad. Blood samples were collected from all patients during the period of Oct.2013 until of Jan. 2014. Anti - toxoplasma antibodies in the sera of all samples by using two tests, Latex test (LAT) and ELISA (IgG), (IgM) while, the proinflammatory cytokine were estimated by evaluation of the cytokine such as (IL - 6, IL - 8, TNF - ?). The results were showed that : ? The infection rate of toxoplasmosis by LAT was (41.53%) which was more sensitive than ELISA IgG (36.85%), and miscarried women were diagnosed by higher anti - toxoplasma IgG antibodies 62/117(52.99%), while pregnant result were lower 30/108 (27.78%). ? The most frequent age group of chronic infection with T.gondii was (23 - 28) year in both miscarriage and pregnant women, and represented by 45.16%, 40% respectively. While the most frequent age group for a single woman was (17 - 22) years, and represent 46.511% of the total number of this group.? Seroprevalence of toxoplasmosis by ELISA IgM test revealed low sensitivity in different studied groups 25/366(6.830%), and miscarried women were diagnosed by a highly significant (P ?0.01) percentage of acute toxoplasmosis14/117(11.965%).and The age group of (17 - 22) years old diagnosed high significant (p?0.01) percentage of acute toxoplasmosis in all studied groups.? According to the distribution of infected miscarried women with toxoplasmosis and gestational age by ELISA IgM the result showed that most of miscarriages were occurred at the first trimester which considered high significant (p? 0.01) 8/14(57.42%). While, chronic infected women at the second trimester (4 - 7 month) diagnosed by significantly (P?0.01) higher percentage of miscarried 24/62(38.71%).? The level of pro - infalmmatory cytokine (IL - 6) in acute infected miscarried women with toxoplasmosis distincted with a significantly high increase (P? 0.05) (177.31±12.53 Pg/ml) in comparison to chronic infected one (119.36 ±14.07 Pg/ml).While, chronic infected pregnant women was low significantly (P ?0.01) (48.41± 2.79 Pg/ml) in comparison to acute infected one and other studied groups, ? The acute infected singles was (118.98± 15.68 Pg/ml) higher non - significantly (P?0.05) than chronic infected one (112.65 ± 17.91 Pg/ml) and both disease activity were significantly higher than its level in healthy singles.? The level of TNF - ? in acute infected miscarried women distincted with significantly higher (P?0.05) (97.46 ± 5.37 Pg/ml) in comparison to chronic infected women (69.55 ± 4.58 Pg/ml), Whereas the mean level of TNF - ? in pregnant infected women during acute phase (62.31 ± 3.82 Pg/ml) was significantly (P?0.05) higher than chronic infection (21.42 ±2.74 Pg/ml)? Single infected women showed high significant increase (P?0.05) of TNF - ? level (50.48 ± 7.42 Pg/ml) in comparison to chronic infected one (35.46± 5.36 Pg/ml) and both disease activity scored high significant increase (P?0.05) of TNF - ? in comparison to healthy singles (18.29 ± 1.02 Pg/ml).? Finally, the mean level of IL - 8 in miscarried women with positive infection with T. gondii during acute phase (187.92 ± 15.38 Pg/ml) was significantly (P?0.05) higher than chronic phase of infection (140.57 ± 13.87 Pg/ml).Whereas the mean level of IL - 8 in acute infected pregnant women (110.32 ± 9.13 Pg/ml) was higher significantly (P?0.05) than healthy pregnant (91.49 ± 7.59 Pg/ml) and healthy singles (88.82 ± 5.62 Pg/ml).? Infected single women showed highly significant (P?0.01) increased levels in both diseases activity in comparison to single women without infection (88.82± 5.62 Pg/ml).

The results reved that 66 isolates are belonging to bacteria of Gram negative (57.4%), 25 (37.78 %) Escherichia coli, 22(33.33%) Proteus mirabilis, 9(6.06%)Klebsiella pneumonia, 5(7.57%) Enterobacter spp for 4 (25%) Enterobacter cloacae and 1(5.51%) Enterobacter aerogenes and5(7.57%) Pseudomonas aeruginosa by using diagnostic phenotypic, biochemical tests and confirm the diagnosis using regular aPI20E. Investigation of some virulence factors showed that both Escherichia coli and Proteus mirabilis produced haemolysin 52% and 90.9% respectively. The production of biofilm by local isolates was detected in Congo - red way, Isolates of Escherichia coli and Proteus mirabilis had been shown the ability to produce biofilm 92% and 90.9% respectively. The results showed that all isolates of Proteus mirabilis produced urease by 100%, while the results detect that the isolates of Escherichia coli not able to produce this enzyme. Proteus mirabilis showed ability to produce swarming with 100%. Siderophore production by Escherichia coli and Proteus mirabilis was 48%, 9% respectively. Eschrichia coli, and Proteus mirabilis produced bacteriocin with percentag of 32% and 50% respectively.The production of ? - lactamase by Eschrichia coli and Proteus mirabilis was 60% , 40.9% respectively, also the isolated had the ability to produce the Extendended spectrum ? - Lactamase enzyme by using disc Approximation, The production from each ofEschrichia coli and Proteus mirabilis 12%, 31.8 % respectively. Results of Metallo? - Lactamase by using the Imp - EDTA combination indicated that E.coli and P.mirabilis were 12% and 13.6% respectively. Isolates of E.coli showed highest resistance rate 92% for Augmentin while isolates of P.mirabilis showe higher resistant to cefotaxime 81.8%. The results showed that multiple resistance pattern for antibiotic 43 (91.5%) resistant to (2 - 5) antibiotics, Isolates of E.coli showed highest multiple resistance rate 92% while isolates of P.mirabilis rate 90.9%. The Minimal inhibitory concentration (MIC) for namely two antibiotics Cefotaxime, Ceftazidime were determined.MIC values of these antibiotics ranged between (2 - <1024), (4 - <1024) µg\ml E.coli and (2 - <1024), (8 - <1024) µg\ml P.mirabilis respectively. The results of molecular detection of ESBL genes (bla TEM and bla SHV) by using PCR technique, (9) samples from (10) total, divided into 3(100%) E.coli and 6(85.7%) P.mirabilis were harboring bla TEM gene based on the presence of 950 bp bands in 1% agarose gel. while results detect that the isolates of Escherichia coli and Proteus mirabilis not harboring bla SHV gene.
