Effect of Bushen Yisui Capsule on the pathological morphology of spinal cords in experimental autoimmune encephalomyelitis mice (hematoxylin-eosin staining).

In the normal group (A), the spinal cord had intact structure and no infiltrating inflammatory cells. In the model group (B), a large number of lymphocytes had infiltrated and formed typical sleeve-like changes at day 20 after immunization. In the hormone (C) and Bushen Yisui Capsule medium-dose (D) groups, pathological changes were ameliorated to varying degrees. At day 40 after immunization, a large number of neurons exhibited pyknosis and pathological changes were reduced. Scale bars: 50 μm.
