Effect of Gekko on Guinea pigs of Experimental Autoimmune Myositis / 中国实用内科杂志

ABSTRACT

Objective To investigate the effect of Gekko on experimental autoimmune myositis(EAM)animal model.Methods From Nov.2003 to May.2004,in the first hospital of Ji Lin university,Guinea pigs were immunized with rabbit muscle homogenate in Freund's adjuvant and a generalized myositis fundamentally similar to humanpolymyositis was established.These animals were divided at random into A,B,C,D groups.A group were treated with small dose Gekko [1 250 mg/(kg?d)],B group were treated with large dose Gekko [3 750 mg/(kg?d)],C group were treated with preinisone [3 mg/(kg?d)],D group received no treatment.Sign,serum muscle enzyme,electromyography(EMG)and muscle biopsy changes were compared.Results A,B,C groups became better.D group showed no significant change.Conclusion Gekko is effective in therapy of EAM guinea pigs.The result of this study provides an evidence that Gekko mightbe used for the treatment of PM.
