摘要
目的 :观察5 %N—乙酰—L—半胱氨酸 (NAC)口服液对小鼠醉酒后血清乙醇浓度和肝、胃组织乙醇脱氢酶活性的影响。方法 :用生理盐水或5 %NAC口服液灌服小鼠30min后 ,再灌服白酒 ,记录小鼠翻正反射消失 (醉酒 )至恢复 (醒酒 )所需时间及24h内小鼠的死亡只数 ;另对小鼠以相同灌服方法连续6d灌服后眼眶取血并处死小鼠 ,立即取出其肝脏和胃 ,分别用生化比色法测定血清乙醇浓度和肝、胃组织乙醇脱氢酶活性。结果 :在醉酒实验中 ,与对照组比较 ,服用5 %NAC口服液组小鼠从饮酒到醉酒的时间明显延长 (P<0 01) ,醒酒时间明显缩短 ,且小鼠的死亡率明显降低 (P<0 05) ;服用5 %NAC口服液组小鼠血清乙醇浓度明显低于单纯服用白酒的小鼠 (P<0 01)。结论 :5 %NAC口服液具有解酒作用。
OBJECTIVE:To investigate the effects of N-acetylcysteine(NAC)on the concentration of ethanol in serum and the activities of alcohol dehydrogenase in liver and stomach tissue in alcoholic mice.METHODS:All mice were given p.o white spirit30min after p.o saline or5%NAC solution,and the durations from the disappear of righting reflex to recovery in mice were recorded and the number of dead mice in24hours were countered;With the same procedure for six days,the mice were killed by withdrawaling blood from orbit,and taken out the liver and stomach immediately,the concentrations of ethanol in serum and the activities of alcohol dehydrogenase in liver and stomach were measured by chromatometry and colorimetric method respectively.RESULTS:In drunk test,5%NAC solution significantly postponed the time from p.o white spirit to the disappear of righting reflex(P<0.01),shortened the duration of temulence and decreased the mortality rate of mice(P<0.05)comparing with control group;The serum concentration of ethanol in5%NAC solution group was obviously lower than that in simple p.o white spirit mice(P<0.01).CONCLUSION:5%NAC solution might alleviate alcoholism.
