摘　　要：目的观察土藤草颗粒对微晶型尿酸钠(monosodium urate,MSU)致家兔急性痛风性关节炎模型的药效学作用。方法选用取雄性日本大耳白兔,随机分为正常对照组,模型对照组,阳性药秋水仙碱组(0.18 mg·kg^(-1)),土藤草颗粒高、中、低剂量组分别为600、300、150 mg·kg^(-1)。通过家兔左后肢膝关节腔内注入MSU的方式建立急性痛风性关节炎模型,给药5天后收集关节液,检测关节腔积液中的白细胞数,测定关节液中炎症细胞因子白介素-6(interleukin-6,IL-6)、白介素-8(interleukin-8,IL-8)、肿瘤坏死因子-α(tumour necrosis factor-α,TNF-α)、白介素-1β(interleukin-1β,IL-1β)、前列腺素E2(prostaglandin E2,PGE2)含量;采血检测血尿酸值,给药前后血清中尿素(urea,UREA)、胆固醇(cholesterol,CHO)、血肌酐(serum creatinine,Cre)、血糖(glucose,GLU)及甘油三酯(triglyceride,TG)含量。结果土藤草颗粒高、中、低剂量组给药5 d后关节腔内白细胞数均有所下降,中剂量组与模型对照组比较有显著性差异(P<0.01);高、中剂量组有降低血尿酸的趋势;土藤草颗粒对家兔血清中UREA、CHO、Cre、GLU及TG含量均无影响;与模型对照组比较,土藤草颗粒高、中、低剂量组IL-6、IL-8、TNF-α及PGE2含量均明显降低,其中高、中、低剂量组的IL-6、TNF-α含量,高、中剂量组IL-8含量及中剂量组PGE2含量与之比较有显著性差异(P<0.01);土藤草颗粒高、中、低剂量组可以一定程度上降低关节液中IL-1β含量。结论土藤草颗粒对MSU致急性关节炎家兔模型有明显的治疗作用,可以减少动物关节腔内白细胞数量、抑制炎症细胞因子的表达,降低血清中尿酸含量。Objective To observe the pharmacodynamic effect of Tutengcao granules(TTC)on monosodium urate-induced acute gouty arthritis model in rabbits.Methods Male Japanese big-eared white rabbits were randomly divided into normal control group,model control group,colchicine group(0.18 mg·kg^(-1)),high(600 mg·kg^(-1)),medium(300 mg·kg^(-1))and(150mg·kg^(-1))low-dose groups.An acute gouty arthritis model was established by injecting monosodium urate(MSU)into the knee joint cavity of the left hind limb of rabbits.Five days after injection,synovial fluid was collected.The number of white blood cells in joint effusion was detected,and the contents of inflammatory cytokines interleukin-6(IL-6),interleukin-8(IL-8),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and prostaglandin E2(PGE2)in joint fluid were measured.Blood was collected to detect the blood uric acid value,and the serum urea,cholesterolesterol(CHO),serum creatinine(Cre),glucose(GLU)and triglyceride contents(TG)before and after administration.Results The number of white blood cells in the joint cavity of the TTC high,medium and low dose groups all decreased after 5 days of administration,and there was a significant difference between the medium dose group and the model control group(P<0.01).TTC high-and medium-dose groups tended to reduce blood uric acid.TTC had no effect on the contents of UREA,CHO,Cre,GLU and TG in rabbit serum.Compared with the model control group,the contents of IL-6,IL-8,TNF-αand PGE2 in the high,medium and low dose groups of TTC were significantly reduced.Among them,the contents of IL-6 and TNF-αin the high,medium and low dose groups were significantly reduced.There was a significant difference between the IL-8 content in the highdose group and the medium-dose group and the PGE2 content in the middle-dose group(P<0.01).TTC high,medium andlow dose groups can reduce the IL-1βcontent in synovial fluid to a certain extent.Conclusion TTC has a significant therapeutic effect on the MSU-induced acute arthritis rabbit model.It can redu
