This study is designed to evaluate the effect of hypothyroidism on reproductive efficiency of adult male rats. Hypothyroid state was induced by administration of anti-thyroid drug propylthiouracil (PTU) (15 mg/kg b.w) orally by gavage for 45 days. Twenty adult male rats of (146-200gm) body weight were used in this study and divided into two groups: control group and PTU treated group. At the end of the experimental period, the rats were euthanized via chloroform . Blood was collected in order to determine serum levels of some hormones, including thyroid stimulating hormone (TSH), thyroxin (T4), triidothyronine (T3), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone(T). Semen analysis was also done. The results of hormones assay showed that there was a significant increase (P≤0.05) in the TSH while there were a significant decrease (P≤0.05) in the serum concentrations of T4, T3, T, FSH and LH. Semen analysis showed that there was no significant difference in the sperm count while there was a significant decrease (P≤0.05) in the individual motility whereas; there was a significant increase (P≤0.05) in the abnormal and dead sperm. Thus PTU-induced hypothyroidism can causes impairment of reproductive efficiency of adult male rats.

The current trail designed toevaluate the effectivenessofusing small intestinalsubmucosa ( SIS ) to accelerate healing of Achilles tendon in thestray local breeddog .Ten healthy dogs of both sexeswere usedin thepresent studywhich randomly divided into two equal groups. Thefirstgroup;Achilles tendon acutetransversely transectedand sutured via cross mattress technique with silk suture materialwith supporting ofgypsona.The second groupacute transected tendon sutured andtreated with thesmall intestinal submucosal patch .All operative dogs inspected clinically,grossly as well ashistopathologically during different periods. Results obtained in the first group showed no contamination, no complicationsand there was no anatomical distortions were detectedat operative site except there is adhesion between tendon and neighboring tissues in the first group healing was uncompleted, suture material still presence up to 90 day.At treatment groupclinically animals lame and sign of mild stiffness appeared for three days, no serious complications, grossly was no adhesion detected, the submucosa subsided completely and complete healing occurs at 90 days postoperatively.Histologicallyatcontrol group 30 days post operativelyuncompleted healing, moderate fibroblast proliferation and inflammatory cells were presence, but at 90 dayspresence of dense connective at the site of operation. In treatmentgroup healing progress, autograft is mostly atrophied and organized with granulation at 90 days,hence healing completed perfectly at this period. In conclusion The repairing of acute transverse cutting of Achilles tendon was significantly accelerated with small intestinal submucosal layer which was absorbed andimproves the tissue quality render the native one .

The experiment was carried out in twelve adult healthy ' dogs of both sexes via closed system of anesthesia. The animals were divided into two group's six animals of each. The first group was treated with a protocol of thiopentone sodium I.V. at the dose (20mg/kg B.wt, premedicated with diazepam . The second group was treated with protocol of propofol I.V. (2mg /kg B.wt) premedicated with diazepam and undergoing pneumoperitoneum with CO2 anesthesia maintained with halothane 2%. The anesthetic, behavioral, biochemical changes were recorded during different periods. The results showed respiratory depression but marked hypoxia not observed at early duration of anesthesia. The endotracheal tube freely introduced within 3-2.5 min. The CO2 gas smoothly delivered into the abdomen without serious complications. In the second group, the induction was rapid with smooth and unexcited recovery and excellent muscle relaxation. In conclusion, the two combination proved to be an effective anesthetic protocol and adequate for minor rapid surgical interventions

This study was carried out to evaluate the effect of sub-clinical mastitis and sex of birth on physico chemical composition of milk for some species of farm animals (Cows, Sheep and Goats ) in Al-Diwania province during a period from March to August 2012. A total of (120) samples of raw milk includes (40) samples for cows, (35) samples for sheep and (45) samples for goats were used in this study. The results of this study revealed that there was a significantly difference (P

The objective of the present work was to evaluate Hemogram, acid-base balance, blood gas analysis and acute phase response in cattle infected with anaplasmosis in Mosul,Iraq.The study were conducted on (167), local cattle breed 2-5 years old of both sexes. Eighty local cattle breed out of (167) were clinically infected with Aanaplasam marginale since the causative Rickettsia diagnosed by Giemsa stained blood smears and confirmed by indirect Elisa test. (20) clinically normal cattle were served as controls. Results indicated statistically significant decrease (P

The present study was conducted to evaluate the effect of Cumin on diabetes mellitus induced by alloxan in rats. Male Wister rats were used, and randomly divided into five groups (6-8 rats for each group): The first group: was administered distilled water and served as normal control, the second group: induced diabetes by single subcutaneous injection of alloxan 100 mg/kg.body weight and served as diabetic control, the 3,4,5 groups was administered 50,100,200 gm/kg of rat's forage respectively for four weeks, then diabetes are induced in this groups by same route as above. Cumin treatment in all doses lead to significant decrease glucose levels, and triglyceride and significant decrease in cholesterol level in dose 100, 200 gm/kg of forage and no change occur in total protein level. These results indicate that cumin have a role in delaying of diabetes through the effects of cumin in decrease some biochemical parameters

Fourty locally white soft cheese random samples were collected from different markets of Baghdad Algadeda city in order to investigate the presence of Salmonellae Spp. in cheese which produced and consumed locally in Baghdad. The samples were collected during the period from December 2011 to March 2012. The samples were directly transferred to the laboratory and analyzed immediately without further storage. The isolation and identification methods include: (pre-enrichment) culture stage by peptone water then (Selective enrichment) culture stage by selenite broth after that culturing on sold (Selective media) which was Bismuth Sulphate agar. The biotyping by using API strip according to the API 20E miniaturized identification system for Salmonella SPP.. The isolated Salmonella strains were transferred on Triple Sugar Iron agar to undergone stereotyping at the Institute of Public Health,Baghdad,Iraq. Data revealed that 2 out of the total 40 (5%) of the cheese samples were contaminated with Salmonella spp. Salmonella typhimurium was the only serotype that have been found.

Cast technique includes ten cats (5 male, 5 female) used the polymerizing resin (cold acrylic) to study the bronchial tree and blood vessels. the examination of bronchial tree of the cats (felis catus) Lung is done by using cold resin in order to prepare cast specimens. The diameter of right principal bronchi of cats mean (7.34 mm± 0.36) and diameter of left principal bronchi means (6.07mm 0.36). The right principal bronchi large than left principal. The air flow in right Lung faster than the left. This result is supported by the researcher .These results are obtained from the cast model showing that the pulmonary trunk divides into right and left pulmonary arteries after arising from the right ventricle of heart. The right pulmonary artery the diameter about (4.18 mm) and diameter of left pulmonary artery about (3.40 mm) that the right pulmonary larger than the left pulmonary artery
