Abstract:
Objective: Effects of cholesterol oxides (Ch-Ox) on plasma prostacyclin (PGI 2) and endothelin (ET) levels of rats in different selenium (Se) status were investigated. Methods: Weaning male Wistar rats were fed Se deficient diet (containing Se 0.038 mg/kg) and stock diet (Se 0.326 mg/kg, control group) respectively, for 13 weeks. One of Ch-Ox, cholestane-3 beta, 5 alpha, 6 beta-triol (3-triol) was injected into the rats through tail vein.24 h after treatment, the plasma PGI 2, thromboxane A 2 (TXA 2) and ET of animals were determined by radioimmunoassay. Results: Blood Se content, glutathione peroxidase activity and plasma PGI 2 levels of Se deficient rats were significantly lower than that of the control group (P
