摘要
目的 探讨美洛昔康凝胶 (MelG)对佐剂性关节炎(AA)大鼠的治疗作用以及治疗效果与MelG血药浓度和局部药物浓度之间的关系。方法 采用FCA诱导大鼠AA ,用Volumemeter测定大鼠足爪容积 ,用HPLC测定MelG的血药浓度和足爪局部药物浓度 ,将足爪肿胀度与MelG的血药浓度或局部药物浓度作相关分析。结果 MelG明显抑制AA大鼠继发性炎症 ,MelG组大鼠血药浓度低于Mel组 ,足爪局部药物浓度则明显高于Mel组 ;AA大鼠继发性足爪肿胀度与MelG的足爪局部药物浓度间呈显著负相关。结论 MelG对AA大鼠的治疗作用与其足爪局部药物浓度高有关。
Aim To study the effects of Meloxicam gel(Mel G)on AA in rats,and the relationship between therapeutic effects and Mel G in tissue or serum. Methods The model of AA was induced by intradermal injection of Freunds complete adjuvant(FCA) in rats,the effects(hindpaw swelling volume)of Mel G on AA rats were observed following Mel G tc. A high performance liquid chromatography(HPLC)method with ultraviolet detection was set up to determine the concentration of Mel in serum and local tissue. Results Mel G significantly inhibited secondary inflammation of AA rats. The concentration of Mel G was lower in serum and higher in local tissue than that of Mel tablets. A significant linear correlation in a negative manner existed between local tissue concentration of Mel G and hindpaw swelling volume. Conclusion Therapeutic effects of Mel G on AA in rats were associated with higher tissue concentration of Mel G.
