五味子合剂对冻融蟾蜍脑组织的组化影响

本实验采用显微镜和722分光光度计分别观察测定了冻融蟾蜍脑组织碱性磷酯酶(AKPase)活性,及五味子合剂的保护效应,结果表明,药物复温组血浆脂质过氧化物(LPO)和红细胞的malondialdehyde(mda)含量显著低于对照组(P<0.01);全血谷光甘肽过氧化物酶(GSH-Px)活性显著高于对照组(P<0.01);脑组织AKPase活性显著高于对照组呈强阳性。提示:五味子合剂具有抗脂质过氧化,保护GSH-Px酶活性,对冻融脑组织能间接提高机体清除超氧自由基和羟自由基的能力。这为组织器官的保存和移植提供了理论依据。

Effects of Diazepam on Rat Cholinesterase andMembrane Stability of Red Cell in vitro

The results confirmed that diazepam inhibits the cholinesterase in rat serum,red cell,corpus striatum and diaphragm in vitro,that the higher the diazepam concentration,the stronger the cholinesterase inhibition,and that diazepam is a reversible inhibitor to acetylcholinesterase and diazepam has a stabilizing action on red cell membranes.The role of these effects of diazepam in the treatment of organic phosphate poisoning is discussed
