本文报道了不同剂量ＣＳ２染毒后和同剂量ＣＳ２染毒不同时间后大鼠血清中高密度脂蛋白胆固醇（ＨＤＬ－Ｃ）及其亚组分（ＨＤＬ２－Ｃ，ＨＤＬ３－Ｃ）含量变化的研究。结果表明：染毒结束时，各染毒组（１２０、２４０、３６０ｍｇ／ｋｇ）与对照组比较，ＨＤＬ－Ｃ及ＨＤＬ２－Ｃ、ＨＤＬ３－Ｃ均未见显著性差异（Ｐ＞０．０５）。随染毒时间的延长（从０→２１天→４９天），染毒组（３６０、１２０ｍｇ／ｋｇ）血清中（与对照组比较）ＨＤＬ－Ｃ及其亚组浓度也未见显著性改变。表明：在本实验条件下，ＣＳ２对脂质的逆向转运过程无明显的毒性作用，对这一过程中主要的环节（包括重要代谢酶类）无明显影响。提示：肝外组织脂质合成增加且逆向转运并未加速而致脂质堆积，可能是ＣＳ２导致脂质代谢障碍，乃致心血管毒性作用的机制之一。
This paper reports the changes of HDL-C and HDL-C, HDL-C and HDL-C contents in rat serum after different doses of CS2 and different doses of CS2. The results showed that there was no significant difference in HDL-C, HDL2-C and HDL3-C between the two groups (P0.01, P0.01) . With prolonging of exposure time (from 0 → 21 days → 49 days), HDL-C and its subgroup concentration did not change significantly in the serum of the treated group (360,120 mg / kg) compared with the control group. The results showed that under the experimental conditions, CS2 had no obvious toxic effects on the reverse transport of lipids, and had no significant effect on the main links (including important metabolic enzymes) in this process. It is suggested that the increase of lipid synthesis in extrahepatic tissues and the reverse transport did not accelerate the accumulation of lipids, which may be one of the mechanisms of cardiovascular toxicity caused by CS2 leading to dyslipidemia.
