曲安奈德乳剂对佐剂型关节炎模型的治疗作用

目的采用佐剂型大鼠类风湿性关节炎模型评估曲安奈德棕榈酸酯脂质微球注射液对关节炎的疗效。方法采用弗氏佐剂给大鼠单侧造模后,分别于阳性对照组、受试药组和空白乳剂组大鼠双侧踝关节腔内一次性给予阳性对照药(曲安奈德注射液2.0 mg.kg-1)、受试药(曲安奈德棕榈酸酯注射液2.01、.0、0.5 mg.kg-1)及空白乳剂。每3 d检测1次各组双侧后足的肿胀度,直至给药后第12天采集所有动物血清,用ELISA法检测血清中IL-1β及TNF-α。并取原发侧踝关节组织及膝关节滑膜组织进行病理组织学观察及用免疫组化法测定MMP-3。结果曲安奈德棕榈酸酯注射液关节腔内注射可抑制佐剂型类风湿性关节炎模型大鼠的足肿胀度;降低血清IL-1β、TNF-α水平;减轻造模形成的各种组织病理学变化;抑制原发部位膝关节滑膜组织MMP-3水平。以上作用强度均与阳性药相当。结论曲安奈德棕榈酸酯注射液对佐剂型大鼠类风湿性关节炎模型有强大的治疗作用,且药效与阳性药曲安奈德注射液相当。

Effects of triamcinolone acetonide palmitate on rheumatoid arthritis model induced by adjuvant in rats

Objective To investigate the effects of triamcinolone acetonide palmitate(TAP),a new dosage form of triamcinolone acetonide for injection(TA),on the rheumatoid arthritis model induced by adjuvant in rats. Methods The constitutional and secondary feet swell degrees were measured once every 3 days since the next day of building model.The drugs were injected in left and right ankle joint cavities only once when the model constructions have succeeded(18 th day after building model).The measure of constitutional...
