| Abstract |
Effects of 5-methyl-7-diethylamino-s-triazolo-1, 5-a) pyrimidine (trapidil, Rocornal), a therapeutic agent for ischemic heart disease, on various types of experimental hyperlipemias were studied. With administration of trapidil, elevation of serum high density lipoprotein cholesterol (HDL-C) levels and reduction in serum total cholesterol (TC), low density lipoprotein and very low density lipoprotein cholesterol (LDL-C) and the ratio of HDL-C to LDL-C (LDL-C/HDL-c) were observed in most disease models. Changes in HDL-C levels and LDL-C/HDL-C in the hyperlipemia induced by lipid-enriched diet in mice and in the hyperlipemia induced by high cholesterol diet in Japanese quails were of statistical significance. Also, amelioration of reduction in HDL-C induced by high fat emulsion plus 6-n-propyl-2-thiouracil in rats was observed to be significant. Moreover, trapidil significantly reduced TC, LDL-C levels and LDL-C/HDL-C in the hyperlipemia in hamsters. To investigate possible mechanisms of therapeutic effects of trapidil, blood enzyme activities in Japanese quails with hyperlipemia were assayed. Trapidil showed increases in plasma lipoprotein lipase and serum lecithin-cholesterol acyltransferase activities. These results suggest that trapidil may be an effective chemotherapeutic agent for treating ischemic heart disease.
