ATP-induced contraction in smooth muscle of chicken anterior mesenteric artery involves both pharmacomechanical and electromechanical couplings via activation of P2X receptor

The relationship between ATP-induced membrane potential and contraction was inestigated in the smooth muscle of chicken anterior mesenteric artery using micro-electrode and tension recording techniques respectively. Application of ATP to en-dothelium-denuded arterial preparations developed concentration-dependent, slow depolarization which started only at concentrations not less than 10 μM. On the other hand the tension recording experiment revealed that ATP produced concentration dependent contractions, which were evident at concentrations lower than those evoked depolarizing response to ATP (as lower 100 nM). Both depolarizing & contracting responses were abolished by the P2X receptor blocker, PPADS (50 μM) but not by P2Y receptor blocker CBF3GA (100 μM), indicating that the excitatory responses of ATP were mediated via activation of P2X receptor. These findings suggest that ATP-mediated contraction is not dependent on membrane depolarization only, at least at low concentrations in the first order branches of chicken anterior mesenteric artery. arabic 21 English 153

Relationship between Body Weight Performance and Plasma Thyroid Hormones in Broiler Hens

o investigate the effect of thyroid hormones Thyroxine (T4) and Triiodothronine (T3) on bodyweight performance in broiler hens. Methodology: The hens were kept in a controlled environment of 50-60% humidity at 31oC in first two weeks than temperature been decreased to 24oC with 24 hr light cycle per day, and were treated gently. Water and feed were provided ad libitum for the all hens. The body weight of the birds detected at the day 2nd, 4th, 6th and 8th week of the experimental period and blood sample detected at the day 14th,28th,42th and 56th day of the experimental period. The data were analyzed by the analysis of variance technique in completely randomized design, while the differences between means were tested by Duncan New Multiple Range Test as per SAS. Results: It was noted that there is a highly significant effect of age, at the level (P ≤ 0.01) on the characteristics of each of the concentration of the hormone T3 and T4 hormone levels and body weight. This study showed that there is a difference in the average concentration of "T4 & T3" for meat birds of different ages. The correlation coefficient manner, "Pearson" between the different qualities of the birds of the meat where it was noted there is a strong inverse relationship between "T4 & T3". arabic 11 English 77

Effect of Intramuscular Injection of Tobramycin on Some Biochemical Parameters in Blood of Sheep

The object of the present study was to assess the possible alterations in blood of sheep that may occur following intramuscular injection of tobramycin. Tobramycin was injected to 10 sheep at a dosage regimen of 5 mg/kg of body weight for 5 successive days. Two types of blood samples (with and without EDTA as an anticoagulant) were collected from the jugular vein before and after the antibiotic course. Tobramycin significantly (p arabic 13 English 83
