仙龙颗粒对佐剂性关节炎大鼠免疫功能的影响

目的:研究仙龙颗粒(XLG)对佐剂性关节炎(adjuvant arthritis,AA)大鼠免疫功能的影响。方法：动物随机分为正常组,模型组,XLG低、中、高剂量组,强的松组,每组10只。福氏完全佐剂诱发大鼠AA模型,造模后第18天开始灌胃给药,观察XLG对AA大鼠足跖肿胀的治疗作用。第30天取材,MTT法检测脾及胸腺淋巴细胞增殖反应,用ELISA法检测脾细胞分泌IgG。结果：与模型组比较,XLG中、高剂量对AA大鼠足肿胀具有明显的治疗作用(P<0.05,P<0.01)；XLG对AA大鼠受抑制的脾淋巴细胞增殖反应具有增强作用(P<0.05),对亢进的胸腺淋巴细胞增殖反应有抑制作用(P<0.05)；XLG对AA大鼠的脾细胞产生IgG水平无明显的作用。结论：XLG能够治疗AA大鼠足肿胀,该作用与调节AA大鼠的异常的免疫功能有关。

Effect of Xianlong granules on immunological function in rats of adjuvant arthritis

OBJECTIVE: To study the effect of Xianlong granules (XLG) on immunological function in the rat of adjuvant arthritis (AA). METHOD: Rats were randomly divided into normal group, AA model group, prednisone group and low, middle and high dose XLG groups, 10 rats in each group. All rats were treated by intragastric administration from the 18 days after arthritis was induced by the complete Freud's adjuvant and the effect of XLG on toes swelling was observed. On the 30th days after modeling, proliferation of the splenic and thymic lymphocytes, and IgG secreted by splenocytes were detected respectively by MTT assay and ELISA. RESULT: Compared with the model group, both the high and middle dose XLG groups had significant therapeutic effects on toes dwelling in the rat of AA (P < 0.05 or P < 0.01); The low, middle and high dose XLG groups strengthened the PHAM-inhibited proliferation of splenic lymphocytes (P < 0.05), and inhibited the PHAM-augmented proliferation of thymic lymphocytes (P < 0.05); XLG did not significantly effect on IgG level secreted by splenocytes in rats of AA. CONCLUSION: XLG can cure toes swelling in rats of AA, which is related with regulation of the abnormal immunlological function.
