摘要
为研究亚硒酸钠(Na2SeO3)对游离脂肪酸(FFA)诱导大鼠肝细胞功能和Caspase 3活性变化的作保护用,采用胶原酶两步灌流法分离培养肝细胞,在细胞培养液中添加FFA和Na2SeO3(0.10μmol/L),测定肝细胞上清液生化指标、细胞增殖率和Caspase 3活性。结果表明,培养液中添加FFA,细胞增殖率降低,肝细胞功能受到影响,Caspase 3活性升高,且FFA的这种作用呈剂量依赖性;Na2SeO3能抑制由FFA引起的肝细胞的上述变化。
The experiment was conducted to study the effect of sodium selenite on liver function and the activity of Caspase 3 induced by free fatty acids (FFA).Primary rat hepatocytes were obtained by two-step collagenase perfusion method.Cell proliferation rates,liver function and the activity of Caspase 3 in FFA-treated group with or without sodium selenite (0.10 μmol/L) were determined.The results showed that:FFA changed doseependently cell proliferation rates, liver function and the activity of Caspase 3, whereas the presence of sodium selenite reversed these alternations.
