新风胶囊对佐剂性关节炎大鼠行为及心肌超微结构的影响

目的：观察新风胶囊（Xinfeng Capsule，XFC）对佐剂性关节炎（adjuvant arthritis．AA）大鼠行为及心肌超微结构的影响。方法：将55只大鼠随机分为5组：正常对照组、模型组、甲氨喋呤（methotrexate,MTX）组，雷公藤多苷片（Tripterygiumwil．fordii glycosides tablet．TGT）组和新风胶囊（Xinfeng Capsule，XFC）组。每组各11只。除正常对照组外．向每只大鼠右后足跖皮内注射弗氏完全佐剂（Freund’s complete adjuvant，FCA）0．1ml制成AA模型。观察各组大鼠行为和心肌超徽结构的变化。结果：各治疗组大鼠的足跖肿胀度和关节炎指数均显著降低。其中XFC组大鼠的自主活动次数显著增加，跳台错误次数明显减少，跳下平台的时间（step—down latency，SDL）延长．反应时间（escape latency，EL）缩短；心肌肌原纤维整体结构完整．大部分嵴突完整。XFC在改善AA大鼠行为及心肌组织超微结构方面，优于其余两治疗组。结论：AA大鼠可出现行为改变及心肌细胞超微结构的变化，XFC既可以全面改善AA大鼠心肌细胞超微结构，同时也能改善其行为。

Effects of Xinfeng Capsule on behaviors and myocardial ultrastructure in adjuvant arthritis rats

OBJECTIVE: To observe the effects of Xinfeng Capsule (XFC), a compound Chinese herbal medicine, on behaviors and myocardial ultrastructure in adjuvant arthritis (AA) rats. METHODS: Fifty-five rats were randomly divided into normal control group, untreated group, methotrexate (MTX) group, Tripterygium wilfordii glycosides tablet (TGT) group and XFC group. There were 11 rats in each group. Except for those in the normal control group, the rats in the other groups were all intracutaneously given 0.1 ml Freund's complete adjuvant in the right hind limb. Changes of behaviors and myocardial ultrastructure of the rats in different groups were observed. RESULTS: Voix pedis' swelling and arthritis index in XFC, MTX and TPT groups were all obviously improved as compared with the untreated group. After XFC treatment, the autonomic activities were obviously increased, number of errors in exercise period and test period were obviously decreased, step-down latency (SDL) was lengthened and escape latency (EL) was shortened. Overall structure of myocardial myofibril and the majority of cristae was intact in XFC group. The effects of XFC in improving the behaviors and myocardial ultrastructure were better than those of MTX and TPT. CONCLUSION: Changes of behaviour and myocardial ultrastructure of AA rats can be observed. XFC can improve the myocardial ultrastructure of AA rats as well as their behaviors.
