摘要： 胶原酶二步灌流法获取原代大鼠肝细胞，用不同浓度的速眠新和保定宁处理，Western blot法测定肝细胞中细胞色素酶P450 3A1（CYP3A1）和细胞色素酶P4502E1 (CYP 2E1)的表达水平。结果表明：通过胶原酶灌流法，每只大鼠可获得2-4×108个肝细胞，成活率约为95%。用速眠新、保定宁处理后，肝细胞CYP3A1和CYP 2E1的表达随速眠新、保定宁浓度的增加和处理时间的延长而呈升高的趋势。原代大鼠肝细胞可用于速眠新药物代谢分子机制的研究，为其临床上合理地应用提供了理论依据。

Abstract: Rat primary cultured hepatocytes were isolated by two-step collagenase digestion method and treated with gradient concentration of SU-MIAN-XIN and BAO-DING-NING, and the expression of cytochrome P450 3A1 (CYP3A1) and cytochrome P450 2E1 (CYP 2E1) were determined by Western blot. The results as follows: 2-4×108 hepatocytes per rat were obtained and the viability was about 95%. The expression of CYP3A1 and CYP 2E1 in rat hepatocytes increased gradually with treatment of SU-MIAN-XIN and BAO-DING-NING. Rat primary cultured hepatocytes can be used for molecular mechanism of SU-MIAN-XIN metabolism, it provides a foundation for its clinical application.
