Abstract:
Objective: To observe the immunohistochemical expression of interferon-? (IFN-?), matrix metalloproteinase -9(MMP-9) in brain and spinal cord tissue, and explore the action mechanism of Zuogui Pills and Yougui Pills on rats with experimental autoimmune encephalomyelitis(EAE). Methods: Lewis rats were immunized with the myelin basic protein (MBP).120 Rats were grouped randomly into nomal group, EAE group, prednisone group, Zuogui Pills group and Yougui Pills group after post immunization (PI). Rats in normal group and EAE group were administered sodium, each 3ml/d, rats in prednisone-group were administered suspension of prednisone after developed clinical signs, each 5mg/kg, rats in Zuogui Pills group were administered suspension of Zuogui Pills, each 2g/kg, and rats in Yougui Pills group were administered suspension of Yougui Pills each 3g/kg. On days 15 and 27 PI, rats were killed and the immunohistochemical staining was performed on the sections of brain and spinal cord. Results: On days 15 and 27 PI, the expression of IFN-? and MMP-9 in central nervous system of EAE group were higher than those in nomal group (P
