描述 Description |
胆固醇是临床生化检查的重要指标。正常情况下,由人体肝脏合成和从食物中摄取的胆固醇会转化为细胞膜的成分,使血液中的胆固醇浓度保持恒定。当肝脏严重病变时,胆固醇水平下降。在黄疸性梗阻和肾病综合征患者中,胆固醇水平往往升高。 Cholesterol is an important indicator of clinical biochemical examination. Under normal circumstances, the cholesterol synthesized by the body in the liver and taken from food will be converted into a component of cell membranes, and keep the concentration of cholesterol in the blood constant . When the liver is severely diseased, cholesterol levels decrease. In patients with jaundice obstruction and nephrotic syndrome, cholesterol levels tend to rise. |
