As the average life span have been lengthened and the rate of senile population have been raised, chronic degenerative diseases incident to aging has been increased rapidly and become a social problem. With this social background, recently, the facts that oxygen radicals(OR) have toxic effects on Central Nervous System and Peripheral Nervous System and cause neuropathy such as Parkinson's Disease, Alzheimer Disease have been turned out, and accordingly lots of studies on the mechanism of the toxic effects of OR on nerves, the diseases caused by OR and the approaches to curing the diseases have been made. The purpose of this study is to examine the toxic effects caused by Glucose Oxidase(GO) and the effects of herbal extracts such as Chilbokyeum(CBY), Chilbokyeumga Acori Rhizoma(CAR), Acori Rhizoma(AR) on the treatment of the toxic effects. For this purpose, experiments with the cultured cell from the cerebrums of new born mice were done. The results of these experiments were as follows. 1. GO, a oxygen radical, decreased the survival rate of the cultured cells on NR assay, MTT assay and amount of neurofilaments and increased the amount of total protein, lipid peroxidation and the amount of LDH. 2. CBY have efficacy of increasing the amount of neurofilaments and total protein and decreasing lipid peroxidation and the amount of LDH. 3. CAR have efficacy of increasing the amount of neurofilaments and total protein and decreasing lipid peroxidation and the amount of LDH. 4. AR have efficacy of increasing the amount of neurofilaments and total protein. From the above results, It is concluded that Chilbokyeumgamibang has marked efficacy as a treatment for the damages caused in the GO-mediated oxidative process. And Chilbokyeumgamibang is thought to have certain pharmacological effects on controlling over aging and treating Dementia. Further clinical study of this pharmacological effects of Chilbokyeumgamibang should be complemented.

This study was done to investigate effects of SR, CF and AR to angiogenesis of cerebral tissues, protecting damage of cerebral neurons and activating them in cerebral contusion-induced rats. I observed these conclusions as follows ; 1. Observation of VEGF-immunoreactive cells : Groups of administered AR were not meaningful in increasing VEGF-immunoreactive cells for 3 days and 7 days, groups of administered SR meaningfully increased them to control groups in all groups, and groups of administered CF meaningfully increased them to control groups in all groups, too, interestingly, increased double to control group for 7 days. 2. Observation on cerebral neurons by Cresyl violet stain : Dendrites and axons of groups of administered SR, AR for 3 days were clearly observed to control group. Cerebral neurons of groups of administered CF for 3days and 7 days were increased a little, but were not meaningful. In conclusion, AR will be careful of being used in cerebral contusion. CF and SR were effective to activating cerebral hemokinesis by inducing angiogenesis in trauma of tissue, but weakly to protecting trauma of cerebral neurons and activating them. I think more studies will be done in these facts.
