In recent years, the activity of anaesthetic propofol on biological processes has been attracting attention. The effect of propofol on biochemical indices in animals is unknown. In this study, we examined the effects of propofol on lipid profile, antioxidant indices, and cardiovascular marker (CVM) enzymes in rats. The study consists of three groups of seven rats each. Group one received corn oil (Control) while groups two and three received propofol (doses of 2 and 4 mg/kg body weight, resp.). Results showed that administration of propofol caused a significant (P < 0.05) and dose-dependent increase in the levels of total bilirubin. Propofol at 2 and 4 mg/kg increased the levels of serum total cholesterol by 74% and 55%, triglycerides by 97% and 115%, and LDL-C (low-density lipoprotein-cholesterol) by 45% and 73%, respectively, while HDL-C (high-density lipoprotein-cholesterol) decreased by 41% and 54%, respectively. Propofol significantly (P < 0.05) increased the levels of the hepatic reduced glutathione (GSH) and activities of GSH-dependent enzymes. Propofol at 2 and 4 mg/kg increased the activities of CVM enzymes: lactate dehydrogenase by 1.7 and 1.8 folds and creatinine phosphokinase by 2.0 and 2.1 folds, respectively. Taken together, propofol increased the levels of GSH and GSH-dependent enzymes but adversely affected the lipid profile of the rats.
近年来,麻醉剂丙泊酚对生物过程的作用一直备受关注。丙泊酚对动物生化指标的影响尚不清楚。在本研究中,我们检测了丙泊酚对大鼠血脂、抗氧化指标和心血管标志物(CVM)酶的影响。该研究包括三组,每组七只大鼠。第一组给予玉米油(对照组),而第二组和第三组给予丙泊酚(剂量分别为2和4毫克/千克体重)。结果显示,给予丙泊酚导致总胆红素水平显著(P<0.05)且呈剂量依赖性升高。2毫克/千克和4毫克/千克的丙泊酚分别使血清总胆固醇水平升高74%和55%,甘油三酯水平升高97%和115%,低密度脂蛋白胆固醇(LDL-C)水平升高45%和73%,而高密度脂蛋白胆固醇(HDL-C)水平分别降低41%和54%。丙泊酚显著(P<0.05)提高了肝脏还原型谷胱甘肽(GSH)水平和GSH依赖性酶的活性。2毫克/千克和4毫克/千克的丙泊酚分别使CVM酶活性升高:乳酸脱氢酶升高1.7倍和1.8倍,肌酸磷酸激酶升高2.0倍和2.1倍。综上所述,丙泊酚提高了GSH和GSH依赖性酶的水平,但对大鼠的血脂产生了不利影响。
