Effect of erhuangfang on cerebral and spinal demyelination and regeneration as well as expression of glial fibrillary acidic protein in rats with experimental allergic ncephalomyelitis

Both erhuangfang and hormone can relieve inflammatory reaction of central nervous system and demyelination of EAE rats. On one hand, erhuangfang can regulate reaction of astrocyte in two ways, relieve reaction and proliferation of astrocyte in non-focal region and maintain the protective effect of astrocyte on brain tissue in focal region; on the other hand, hormone can overall inhibit reaction of astrocyte.
