        In other to elucidate the neuroprotective effects of Haeahwan on oxidant-induced neurotoxicity in cultured rat spinal motor neurons, the colorimetric assay such as MTT, NR, LDH, Lipid peroxidation was also carried out after cultured spinal motor neurons from neonatal rat were treated with the medium containing various concentrations of Methylmercuric chloride(MMC) for 8 hours. In addition, the protective effect of Haeahwan water extract extracts on the neurotoxicity induced by oxygen radicals was examined in these cultures. The results were as follows : 1.Survival rate of cultured spinal motor neurons were remarkably decreased by MMC depending on different kinds of concentrations. 2.NR50 of MMC as 50μM. 3.Haeahwan water extract inhibited significantly the increase in LDH activities induced by MMC.

        In order to examine toxic effect of Jangwonhwan on cultured mouse cerebral cortical neurons inhibited by neurotoxicity induced by Xanthine Oxidase/Hypoxanthine(XO/HX), MTT and lipid peroxidation assay were performed after cerebral cortical neurons were preincubated with various concentrations of Jangwonhwan water extract before treatment of cells with XO/HX. The result were as follows ; 1. XO/HX induced cell degeneration such as the decrease of cell viability was measured by MTT in the cultured mouse cerebral cortical neurons 2. Jangwonhwan water extract was effective in the decrease of lipid peroxidation of neurons produced by XO/HX. From the above results, it is suggested that Xanthine Oxidase/Hypoxanthine(XO/HX) induces the inhibition of cell viability in cultuerd mouse cerebral cortical neurons and Jangwonhwan was effective in cultured neurons damaged by XO/HX.
