Total cholesterol(TC),triglyceride(TG)and Apoprotein of 69 cases of coronary heart disease (CVD group),42 cases of cerebrovascular hemorrhage(CVD group)and 82 cases of healthy persons (control group)have been determined in this study.The lowest Tc level with highest TG level in CVH group(P<0.01 vs control group)and highest Tc level with lowest TG level in CVD group(P<0.01 vs CVH group)had been found.It is suggested that the low Tc level may be a risk factor of cerebro— vascular hemorrhage
