Abstract
Changes in coagulative and fibrinolytic activities were studied in rats with hyperlipidemia induced by Triton WR-1339 (T-WR). After intravenous injection of T-WR (150, 200 or 300 mg/kg) into S.D. rats, dose-related increases in plasma lipids (total cholesterol, triglyceride, free cholesterol and phospholipid) were observed. In hyperlipidemic rats that received 300 mg/kg of T-WR, decreases in red blood cell count and Hb value were found. Significant increases in the ma value of the thromboelastogram and the fibrinogen level were observed in these T-WR treated rats. The α2-plasmin inhibitor activity was found to decrease doserelatedly. These results indicate that T-WR induced hyperlipidemia in rats is accompanied with an increase in coagulative activity and an indirect enhancement of fibrinolytic activity.
