血脂是指血浆中所含脂类的总称,其中主要是甘油三酯、总胆固醇和磷脂。它们在血浆中并非以游离形式存在,而是与脂蛋白结合以脂蛋白形式存在,所以高脂血症,应确切地称为高脂蛋白血症。血脂的正常值波动较大,如甘油三酯20～110毫克％,总胆固醇110～220毫克％,磷脂110～210毫克％,但其含量的波动有一定范围。由于高脂蛋白血症,特别是β- Lipids are the general term for lipids contained in plasma, mainly triglycerides, total cholesterol and phospholipids. They are not in free form in the plasma, but rather lipoproteins in the form of lipoproteins, so hyperlipidemia should be exactly what is called hyperlipoproteinemia. Fluctuation of the normal blood lipids larger, such as triglycerides 20 ~ 110 mg%, total cholesterol 110 ~ 220 mg%, phospholipids 110 ~ 210 mg%, but its content fluctuations have a certain range. Due to hyperlipoproteinemia, especially β-
