The Study was performed on the anticonvulsive effects of Woohwangporyonghwan(WPH) and Woohwangporyonghwan except CINNABARIS and REALGAR(WPHCR) in ICR mice pretreated with strychnine, picrotoxin, and caffeine as convulsive agents, and also was done on the accumulation of Hg & AS in organs of ICR mice by ICP hydride generation method. The results were obtained as follows: 1. WPH and WPHCR group showed significant effect in delaying the onset of convulsion induced by strichine, but time to death was effective only in WPHCR group. 2. WPH and WPHCR group were significantly effective in delaying convulsion induced by picrotoxin, and time to death. 3. The anticonvulsive effect of WPH and WPHCR group was not found convulsion induced by caffeine. 4. The accumulation of Hg, AS in liver and kidney of ICR mice was not determined below 50ng/g and below 80ng/g respectively. From the above results it could be concluded that WPH and WPHCR group were effective in the convulsions induced by strychnine and picrotoxin, although the accumulation of Hg & As in liver and kidney was not proved, further study might be necessary to prove the drug safety of WPH included CINNABARIS and REALGAR.
