Evaluation of Triacylglycerol in Hepatocytes and its Relationship with Nefa Serum Value on Slaughtered Cows in Tabriz Abattoir-Iran

Abstract: Fatty liver syndrome (Hepatic lipidosis) or fat cow syndrome is a major metabolic disorder in many dairy cattle's in early period of lactation. The aim of this study was to evaluating fatty liver syndrome in dairy cattle in Tabriz by measurement of hepatic TG and NEFA serum values. The results showed that NEFA has a positive relationship with hepatic TG. Thus, with elevating of hepatic TG, NEFA serum values also increased

Relation between Ascites Syndrome Incidence and Infectious Bronchitis in Broiler Chickens by ELISA Method

Abstract: Infectious bronchitis is an acute viral disease with high contagious and mortality among chicks. The aim of this study was to survey of relation between ascites syndrome incidence and infectious bronchitis in broiler chickens by ELISA method in Iran. Eight Ross strain broiler farm affected by infectious bronchitis were selected in this study. Blood samples were gathered early stages of disease and blood sampling was repeated two times with seven days interval. ELISA serologic test was used for approving the determination of infectious bronchitis. In addition, in order to differential diagnosis of Newcastle and influenza (H 9 N 2 ) some relevant experiments were conducted. The rate of mortality in any farm during rearing, autopsy and the cause of mortality were recorded. Ascites cases were calculated in terms of prevalence. The growth parameters, FCR, final weight, total consumption of grain at each farm were calculated and mentioned. Based on obtained results in this study, the mean rate of mortality caused by ascites syndrome has been increased meaningfully in herds affected by infectious bronchitis compared with control group. In eight understudied farms affected by infectious bronchitis, the mean rate of Ascites mortality was 3% such that the mean rate of Ascites mortality was 0.5% at previous periods. Based on relevant results also final weight mean in affected herds with infectious bronchitis was lower compared with previous periods. Meanwhile, FCR in affected herds with infectious bronchitis was high compared with healthy herds. In this research demonstrated that there is positive correlation between infectious bronchitis and Ascites syndrome and the correlation is significant (p<0.05)

Experimental Study of Apoptosis after Castration in Prostate Tissue

Abstract: The prostate gland is one of the reproductive enclosure glands that its physiological function is necessary for successful reproduction in males. This gland depends on sexual hormones including androgens for its natural function and normal growth and development. So in the case of hyperplasia, hypertrophy or other prostate diseases, the most successful and efficient method of treatment is castration that in some cases is unavoidable. This thesis has been done to survey the effects of the androgen depletion states on the prostate gland and for determining the mechanism of cell death engaged in this state. In this thesis we used two groups of dogs that each group contained 5 dogs. These dogs were under care for 1 month. In this period of time they were surveyed for any possible disease. After this period the dogs in "treatment group were castrated for decreasing the level of the androgen hormones in the blood. The dogs in the "control group" were left intact. After a week of surgery, prostate glands of these dogs were extracted and used for preparing pathological cross sections. These sections have been colored in the TUNEL and H&E methods and then inspected with optical microscope for detecting apoptotic cells. We found that after castration, the size of the prostate gland decreases and microscopically changes of the gland include increased number of apoptotic cells. These results demonstrate that the type of the cell death engaged in prostate gland in androgen deprivation states are Apoptosis

Fatty Liver Syndrome in Dairy Cattle: Relation between Nefa, Apo-A, Ammoniac, Tsh and Total Bilirobin Serum Values in this Syndrom

Abstract: Fatty liver syndrome (Hepatic lipidosis) or fat cow syndrome is a major metabolic disorder in many dairy cattle's in early period of lactation. The aim of this study was to evaluating fatty liver syndrome in dairy cattle in Tabriz by measurement of NEFA, APO-A, Ammoniac, TSH and Total Bilirobin serum values. In this study 10 mL blood samples from 400 Holstein dairy cows were obtained by venoject from jugular vein and then samples in vicinity of the ice sent to the laboratory. In lab, prepared serums froze inside the micro tube. The results showed that NEFA has a positive relationship with ammoniac and total Bilirobin serum values and reverse relationship with APO-A and TSH. Thus, with elevating of NEFA serum values, ammoniac and total Bilirobin also increased and TSH and APO-A contrary diminished

Globalization and Its Impact on Development in Underdeveloped Countries with Based on Iran

ABSTRACT This essay studies the effects of globalization on developing countries Especially Iran and states that globalization is both a chance and a threat, and one should accept the fact that it effects globally on the fates of people. Now if the countries interpret this process according the analytical bases, the result will be distancing from developed countries and their stand-backs. It is proven in this essay that the countries should get out of inactiveness and be mobile and active. They can achieve a constant discourse consciousness through spreading global knowledge. In fact, what is proven in this essay is that the more aware the countries Especially Iran are in saving, producing and spreading knowledge, the more successful decisions they'll make and the more successful they'll be. The research method in this study is library based, analytical and based on creative approaches which make the way to development possible in the new age
