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(150 mg·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-α and PGE2 in the high,medium and low dose groups of TTC were significantly reduced.Among them,the contents of IL-6 and TNF-α in the high,medium and low dose groups were significantly reduced.There was a significant difference between the IL-8 content in the high-dose group and the medium-dose group and the PGE2 content in the middle-dose group(P<0.01).TTC high,medium and low dose groups can reduce the IL-1β content in synovial fluid to a certain extent.Conclusion TTC has a significant therapeutic effect on the MSU-induced acute arthritis rabbit model.It can reduce the number of white blood cells in the animal's joint cavity,inhibit the expression of inflammatory cytokines,and reduce the uric acid content in the serum.
