胆固醇是细胞膜形成不可缺少的物质,但它又能给人体带来种种危害。胆固醇不溶于水,它在血中运转的时候,可沉着于动脉壁。胆固醇积聚于动脉壁后,便不容易转移出来,再加上其他一些因素,最终形成纤维斑块以及斑块引起的动脉粥样硬化。这种病变如果发生在心脏的冠状动脉,便可发展成为冠状动脉粥样硬化性心脏病(冠心病);如果发生在脑动脉,便可发展成为动脉粥样硬化血栓形成性脑梗塞,都可致命。早在二十世纪之初病理学家Aschoff就报告过:在动脉粥样硬化病灶中,有大量的胆周醇沉着。ANitschkow用高胆固醇食饵喂养家兔,发现在
Cholesterol is an indispensable material in the formation of cell membrane, but it can bring various hazards to the human body. Cholesterol is insoluble in water and can settle in the walls of arteries when it is running in the blood. Cholesterol accumulation in the artery wall, it is not easy to transfer out, together with other factors, the final formation of fibrous plaque and plaque-induced atherosclerosis. If the disease occurs in the heart of the coronary artery, can develop into coronary heart disease (coronary heart disease); if occurred in the cerebral artery, can develop into atherothrombotic cerebral infarction, can fatal. Aschoff, a pathologist as early as the early twentieth century, reported that there was a large amount of peritoneal hyperpigmentation in atherosclerotic lesions. ANitschkow fed rabbits with high cholesterol diet and found it in
