Two experiments were conducted to evaluate the effects of early feed restriction on lipid peroxidation, pulmonary vascular remodelling and ascites incidence in broilers under normal and low ambient temperature. In experiment 1, the restricted birds were fed 8h per day either from 7 to 14 d or from 7 to 21 d, while the controlled birds were fed ad libitum.(More)
AIM To study the effects of artesunate (dihydroartemisinine-12-alpha-succinate, Art) on immune function in mice. METHODS Hemolysin concentration was determined by colorimetric method. Serum IgG and C3 contents were measured by single immunodiffusion method. Percentage of lymphocyte transformation, phagocytosis percentage and phagocytic index were counted(More)
The present study was conducted to examine the effect of supplemental L-arginine on pulmonary arteriole protein kinase Calpha (PKCalpha) expression in broilers exposed to cool temperature, to investigate further the molecular mechanisms of supplemental L-arginine on modulating pulmonary vascular functions in hypertensive broilers. Broilers were subjected to(More)
Antagonists of increasing concentrations were added to PRP which had exhibited irreversible aggregation and the extent of deaggregation was determined. Several classes of platelet antagonists with different mechanisms have been undertaken to reverse platelet aggregation induced by ADP, collagen, arachidonic acid, U46619 and PAF. The results indicate that(More)
AIM To study the kinetics of tumor necrosis factor alpha (TNF alpha), interleukine-1 (IL-1 beta), and macrophage inflammatory protein-1 alpha (MIP-1 alpha) gene expression in rat lung after i.p. lipopolysaccharides (LPS) and the effect of dexamethasone (Dex) and ibuprofen (Ibu) on the cytokines gene expression. METHODS The amount of Evans blue in lung was(More)
AIM To observe the effects of nitric oxide and interleukin-10 (IL-10) on inflammatory reaction in mouse alveolar macrophages (AM). METHODS AM from mice were stimulated by lipopolysaccharides (LPS) 10 mg.L-1 and nitric-oxide synthase inhibitor, S-methylisothiorea sulfate (SMT) or nitric-oxide donor, S-nitroso-N-acetyl-D, L-penicillamine (SNAP). The(More)
AIM To study the influence of dexamethasone (Dex), ibuprofen (Ibu), and ligustrazini (Lig) on lipopolysaccharides (LPS)-induced tumor necrosis factor alpha (TNF alpha) gene expression (both mRNA and protein). METHODS TNF alpha in supernatants of human whole blood was measured by ELISA; The TNF alpha mRNA was assessed by slot blot analysis. RESULTS(More)
AIM To study the effects of propylene glycol mannate sulfate (PGMS) on platelet adhesion, aggregation and thrombosis in abdominal aorta in rabbits. METHODS Platelet adhesion assay was performed with a platelet-adhesion-meter. The platelet concentration was determined with an electronic particle counter, and the total radio-activity was determined with(More)
