Abstract:
Aim To examine the protective effects of allopregnanolone against seizure on different animal models.Methods The protective effects of allopregnanolone against maximal electrical seizure (MES) and picrotoxin-induced seizure were studied in C57 mice 15 minutes after vehicle or drug intraperitoneal administration.Results In the MES test, we found that pretreatment with the phenobarbital or allopregnanolone produced a dose-dependent protective effect against seizure. The potency (ED50 value) of phenobarbital in the MES test was 2.40 mg?kg-1, with 95% confidence interval range from 1.22 to 4.72 mg?kg-1. The potency (ED50 value) of allopregnanolone in the MES test was 0.086 mg?kg-1, with 95% confidence interval range from 0.037 to 0.201 mg?kg-1, which was significantly higher than that of phenobarbital (P
