Object : Gliosis becomes a physical and mechanical barrier to axonal regeneration. Reactive gliosis induced by hypoxic brain injury is involved with up-regulation of CD81 and GFAP. The current study was to examine the effect of the Angelica Sinens on CD81 and GFAP regulation after hypoxic brain injury in the astrocyte. Methods : MTT assay was performed to examine cell viability, and cell based ELISA, western blot and PCR were used to detect the expression of CD81 and GFAP. Results : The following results were obtained: 1. Using ELISA, western blot and PCR from the astrocyte after hypoxic injury, CD81 and GFAP expression was seen to have increased. 2. After the administration of Angelica Sinens extract to astrocyte following hypoxic injury, CD81 and GFAP expression was down regulated significantly. The water extract of Angelica Sinens prevented cell destruction by hypoxic induced with $CoCl_2$. Conclusion : These results indicate that Angelica Sinens could suppress reactive gliosis, which disturbs astrocyte regeneration after hypoxic brain injury by controlling the expression of CD81 and GFAP.
