The present study attempted to investigate the pathology underlying the influence of Zuogui pills on myelinolysis in EAE rats. Hematoxylin-eosin and Luxol fast blue staining showed that the myelinolysis foci in the cerebrum, cerebellum, brain stem, and the spinal cord of EAE rats were significantly decreased, along with serum myelin basic protein content following treatment with Zuogui pills.展开更多
