给小鼠腹腔注射二巯基丁二酸钠,20分钟后于小鼠背部皮下注射眼镜蛇毒,观察48小时,与单用蛇毒组小鼠比较,两组死鼠率差异无显著意义(P>0.05)。将二巯基丁二酸钠和眼镜蛇毒混合,置23℃孵育5分钟后在小鼠背部皮下注射,观察48小时,与单用蛇毒组小鼠比较,两组间死鼠率的差异有非常显著意义(P<0.01)。 The mice were injected intraperitoneally with sodium dimercaptosuccinate. After 20 minutes, the mice were injected subcutaneously with Cobra venom for 48 hours. There was no significant difference in the rate of dead rats between the two groups (P> 0.05 ). Sodium dimercaptosuccinate and cobra venom were mixed, incubated at 23 ℃ for 5 minutes and then subcutaneously injected into the back of the mice for 48 hours. Compared with the mice treated with the snake venom alone, there was a significant difference in the rate of dead rats between the two groups Significance (P <0.01).
