摘要: 目的 研究黄芪总提物(total extract of astragalosides,TEA)对佐剂性关节炎(AA)大鼠的治疗作用与其抗氧化作用的关系。方法 测量(AA)大鼠非致炎侧足爪容积和滑膜细胞LPO;测量兔滑膜成纤维细胞的增殖量;间接测量体外超氧阴离子自由基(O2-)和羟自由基(·OH)产生量。结果 TEA 对AA 大鼠的阶段性治疗(90mg·kg-1·d-1,d15~23,ig),不仅有抗关节炎作用,且可使AA 鼠过高的滑膜细胞MDA 水平降至正常;对低水平氧化应激诱导兔滑膜成纤维细胞的增殖反应,TEA(10~40μg·ml-1)有明显抑制作用。TEA(5~80μg·ml-1)对黄嘌呤(X)-黄嘌呤氧化酶(XO)体系以及非酶体系产生O2-有明显抑制作用,高浓度T EA(80μg·ml-1以上)对XO的活性还有抑制作用;TEA(0.05~160μg·ml-1)对Fenton反应(Fe2+-H2O2)产生-OH引起苯甲酸羟化也有明显的浓度依赖性抑制作用。结论 TEA对AA鼠的治疗作用可能与其抗氧化作用有关。

Abstract: Aim The relationshiPbetween the therapeutic effect of TEA (total extract of astragalosides) on adjuvant arthritic (AA)rat s and its antioxidative effects were studied.Methods The volume of non-injected hind paw of AA rat s and malondialdehyde (MAD) content of arthritic synoviocytes from AA rats were measured and the proliferative responses of fibroblast,the level of superoxide anion(O2-)and the hydroxyl radical (-OH)generated in vitro were detected. Results The anti-inflammatory effect of TEA might be related to its antioxidative activity.In vitro low-level oxidative stress promo ted the proliferative responses of fibro blast in rats synovium,which was marked by inhibited by TEA in a concent rat ion-dependant manner.Further study showed that TEA could inhibit NBT reduction induced by both xanthine-xanthine oxidase and no n-enzyme generated O2-,but the inhibitory effect of this compound on activity of xanthine oxidase was obtained only at high concent ration (more than 80μg·ml-1).It was also found that TEA could dose-dependantly inhibit the hydroxylation of benzoic acid induced by Fenton react ion gene rated ·OH.Conclusion TEA has significant therapeutic effects on AA rats,which might be related to its antioxidative effects
