不同剂型生脉散对氧自由基清除作用的比较

研究了生脉注射液、生脉饮、生脉胶囊这3种直接用于临床的成药剂型是否也具有抗氧自由基（羟自由基·OH和超氧阴离子自由基O－2·）作用，并且不同剂型之间是否有差异.用邻二氮菲-Fe2+氧化法测定·OH，用改进的邻苯三酚自氧化法测定O－2·.结果表明，3种剂型生脉散均有清除·OH和O－2·的能力，与对照管比较有高度显著性差异（P＜0.01），各剂型之间无显著性差异（P＞0.05）.

Comparative Study on the Effect on Removing Oxygen Free Radicals with Different Forms of Shengmai Power

To study whether the three proprietary forms——Shengmai injection,Shengmai drink,Shengmai capsule,which can be directly used in clinic,have  the effect of  resistance on oxygen free radical (hydrogen radical ·OH and superoxide anion  radical   O－2·,whether there are any differences between the three.Mensurate ·OH with the oxidation of phenathroline -Fe2+，mensurate  O－2·  with improved pyrogallol auto-oxidation.Results shows that  all of the three forms of Shengmai power are of the ability of  removing  ·OH  and  O－2·;there are not significant differences between the three (P>0.05),but there are significant differences when compared with comparison tube (P<0.01).
