The present study was carried out in ewes to investigate the causes of dystocia andeconomic effect, reared in Basrah governorate (Basra – Iraq ) .The current study was started from August 2017 to May 2018 , and conductedon 60 ewes,1.5-10 years old. Animals were divided into two groups,First treated group: 40 ewes suffered from dystocia. and theSecond normal group: 20 ewes with normal parturition served as a healthy control.Ewes with dystocia were diagnosed on the bases of clinical inspection .The study showed that the ewes that suffered from dystocia have a low serumlevel of calcium compared with control group.

This study was designed to evaluate the ameliorating role of CoQ10 and DHEA and theircombination on norfloxacin induced maternal toxicity and fetal growth retardation in pregnantfemale rats and their fetuses. Twenty pregnant rats were divided equally into 5 groups, 4 animalsper each group as following: Control group (G1): 4 normal pregnant female received0.5ml/animal/day DMSO by using gastric gavages from 5th - 19th day of gestation. First treatedgroup (T1): 4 normal pregnant female received 400 mg/kg norfloxacin daily by gastric gavagesas a single dose. Second treated group (T2): 4 normal pregnant female received orally 400 mg/kgnorfloxacin once daily and after 1hour later injected daily with CoQ10 200 mg/kg IP. Thirdtreated group (T3): 4 normal pregnant female received orally 400 mg/kg norfloxacin once dailyand after 1hour later injected daily with DHEA 25 mg/kg IP. Fourth treated group (T4): 4 normalpregnant female received orally 400 mg/kg norfloxacin once daily and after 1hour later injecteddaily with combination of CoQ10 200 mg/kg and DHEA 25 mg/kg IP for the same period. Alldams were sacrificed at 20th day of gestation and their fetuses were collected and subjected to themorphological examinations. The obtained results showed that exposure to norfloxacin inpregnant female rats during gestational period from 5th -19th day demonstrate clearly increased inresorbed and stillbirth fetuses (dead fetuses at birth), and caused a significant decreased in fetalbody weight, fetal body length, fetal tail length, maternal weight gain and placental weight. It has been concluded that CoQ10 and DHEA prevented and treated morphological anomalies in ratfetuses. Therefore, CoQ10 and DHEA are potential therapeutic antioxidant agents againstfetotoxicity induced by oxidative stress generated by norfloxacin intoxication

The present study was conducted to investigate the effect of androgenic–anabolic steroids Sustanon 20 mg/ kg on oxidative stress. Twenty male rats weredivided into four groups treated for 4 weeks as once weekly treatment. The 1st groupconsidered as control group, the 2nd group injected with sustanon 20 mg/kgintramuscularly, the 3rd group injected with sustanon intramuscularly 20 mg/kg andthen orally dosage of vitamin E 100 mg\kg, and 4th group got orally dosage of vitaminE 100 mg/kg. The results revealed significant decrease in glutathione level in theserum and tissue of brain and liver in sustanon group as compared with control, whilethere is significant increase in malondialdehyde level in the serum of sustanon groupas compared with control The result showed no different between the groups treatedwith sustanon alone and with sustanon and vitamin E.All the pathological changes have been recorded for the sustanon group onlywhile there were no pathological changes for other groups. The gross pathologicalchanges showed congestion of heart and liver in sustanon group.. The microscopicchanges of heart showed vacuolar degeneration of cardiac cells and edema between it.Liver showed necrosis of hepatic cells, infiltration of inflammatory cells. Lungsrevealed pneumonia with thickening of wall of alveoli and bronchioles byinflammatory cells, and emphysema of alveoli. We conclude from this study that sustanon in high dose have an effect onincrease oxidative stress, macroscopic and microscopic pathological changes in heart,liver and lung, and no effect of vitamin E in this study

Heat shock proteins Hsp70 proteins belong to the heat shock protein family, boost cellssurvival in hostile environments, involved in many cellular biological processes. Thepolymorphism of hsp70 gene relates to the possibility of tolerating different stressconditions. This study was carried out during 1st April to 31th June 2016, 20 Arabi Rams,known fertility, 2 – 2.5 years old, from the Agricultural Research Station / College ofAgriculture / University of Basra, Iraq, were used, Semen was collected by using theartificial vagina, after training well. DNA extracted then Polymerase chain reaction(PCR)amplified sequencing, BLAST analysis and multiple sequence alignment were carried out.The results showed two haplotypes, haplotype G1 , haplotype G٢ compared with samegene in GenBank, all mutations were silent except the mutation is site 514 was missenseappeared in G1. It concluded that the Arabi rams in Iraq have new polymorphism ofhsp70 gene which can help cope with difficult environmental conditions

This study was conducted to prepare a database about hair follicles of Shami goat skin and to compare itwith that of Black goat. To achieve this goal, a comparative topographic histological study of 10 areas ofShami goat skin and similar areas of the Black goat skin was performed. Samples of 10 male animals (5)Shami goats and (5) Black goats used in this study were clinically healthy, 1-2 years old . Hair follicles inmost studied areas were of the composite type of primary and secondary hair follicles in both animals exceptfor the ventral surface area of the tail where primary follicles were present only. The length of hair folliclesin Black goats of all studied areas was longer than that of Shami goats. However, the depth of hair folliclesin skin of Shami goats was significantly lower than that of Black goats, indicating that the angle of hairfollicles in Shami goats is greater than those of Black goats. The follicles in Black goats were larger thanthose of Shami goats, indicating that the Shami goats hair was softer than that of Black goats. Shami goatshair had softness more than that of Black goat' hair. This softness is attributed to the increases the ratio ofsecondary hair follicles to primary hair follicles in Shami goats in most studied areas compared with those inBlack goats. The follicular arrangement was studied in both species, however, the triangular arrangement ofthe follicles was predominant in both animals except for the ventral area of the tail, where the trio folliculararrangement appeared only in the Shami goats and did not appear in the Black goats where they spreaduniformly and not in groups.

This work conducted on six healthy adult male (Gazella Subgutturosa) brought from naturalreserve in Qusaybah. The animals were slaughtered and the kidneys were quickly removed. TheRenal width, lengths at superior and inferior poles, thickness and the volume were measured. Adigital vernier caliper was used for performing the measurements. The right and left kidneyswere weighted by digital electrical balance. The data were statistically analyzed. The left andright kidneys were bean in shape, solid in texture and red to brown in color with smooth surface.Each kidney was covered by renal fascia and thin fibrous capsule, Para and pre-renal largeamount of adipose tissue were predominant. The mean weight of the right kidney was heavierthan the left kidney, the left kidney was located more caudally, the kidney/Body weight ratio was(1/303).The cortex medulla index was (1/4). The kidney of gazelle was anatomically similar tothe kidney of sheep and goat; the cortex medulla index revealed that the black-tail gazelle wasefficient for water conservation. The present study has provided important information on therenal morphometry which will be use for wild animal medicine and surgery.

This study carried out in College of Veterinary Medicine /University of Basrah toevaluate the effect of different doses of pumpkin seed oil (PSO) on Thyroid functions inChlorpyrifos (CPF) treated male rats. Fifty adult male rats were used and randomly dividedinto five equal groups, 10 rats per each group: Group 1(control) administered orally cornoil(1ml /kg.bw) , whereas first treated group administered CPF 1/20th LD50 (6.7 mg/kg bw).Group 3, 4 and 5 were administered CPF (6.7mg /kg.bw) plus PSO(20, 40, and 80 ) mg/kg.bwrespectively. The treatments were given once daily by oral gavages for 8 weeks. At the end ofthe experiment, animals were sacrificed and blood samples were obtained for evaluation ofthyroid hormones (T4 and T3 ) and tissue samples from thyroid gland kept in 10% neutralformalin for histopathological examination.The results indicated that male rats treated with Chlorpyrifos demostreated a significantincrease (P<0.05) in thyroid stimulating hormone (TSH) and a significant decrease (P<0.05) inthyroxin(T4) and triiodothyronine (T3) hormones compared with control group.Histopathological examination of CPF treated males showed that thyroid gland revealeddestruction of thyroid follicles with infiltration of macrophages on the site of folliculardestruction. On other hand groups treated with 20,40 and 80 mg pumpkin seed oil inducedimprovement in above cited parameters and histological changes in dose dependent manner

Chronic Hepatitis B is a major global health problem worldwide, However, twoBillion People could be infected with this disease Worldwide. Living organismsrequire varying amounts of heavy metals. Such as manganese(Mn), cobalt(Co) andzinc(Zn). Some heavy metals have bio-importance, but the bio toxic effects of manyof them in human biochemistry are of great concern. Heavy metals are essentialmicronutrients involved in many metabolic processes. One hundred sixty patientsamples and thirty healthy individuals were investigated in this study. All patientsincluded in this research are tested positive for the HBSAg test and their specimenswere examined by profile test which includes (HBS Ab, HBe Ag, HBe Ab, HBc Ab,(IgM-IgG), HCV and HIV) and also viral load (HBV PCR) with unit (copies/ml)were carried to test the patients sera. Manganese, chromium, cobalt, and nickel havelevels were determined by using inductively Coupled plasma- Mass spectrometry(ICP-MS). Results show a significant increase in the concentration of manganese,chromium, cobalt, and nickel in serum of patients with chronic hepatitis B compared to healthy individuals. We conclude that hepatitis B may affect the level of studiedelements in patients infected with HBV.
