Abstract:
Objective To investigate the role of malondialdehyde(MDA),superoxide dismutase(SOD),and interleukin-1β (IL-1β) played in the pathogenesis of acute gouty arthritis and the treatment efficacy of probucol.Methods Acute gouty arthritis model in rat was established with injection of monosodium urate monohydrate (MSU) into the ankle joint cavity,then the joint swelling index was observed periodically,and MDA,SOD,IL-1β,and white blood cell count in the synovial fluid were determined by 72 h.Results The joint swelling index gradually increased,reaching a peak by 11h,and this finding was most obvious in the model group.The joint swelling index in the group treated with high-dose of probucol was significantly lower than that in the model group by 48 h(P＜0.05).The joint swelling indices in the groups treated with moderate and high doses of probucol were lower than that in the model group by 72 h(P＜0.05).The values of MDA in the moderate and high-dose groups were (14.45±3.11) and (11.54 ±3.10) nmol/ml respectively,being significantly lower than that in the model group[(24.46±4.27) nmol/ml,P＜0.01].The amounts of SOD in the moderate and high-dose groups were (25.56±4.51) and (44.61±4.11)U/ml respectively,being higher than that in the model group[(13.32±2.02) U/ml,P＜0.01].The amount of IL-1β in the high-dose group was lower than that in the model group[(15.41 ± 3.12 vs 19.87±3.99)pg,P＜0.05].The white blood cell counts in the moderate and high-dose groups were (11.08±1.64)×l0~7/L and (7.43±1.52) x 10~7/L,being lower than that in the model group[(14.18±2.30)×10~7/L,P＜0.01].Conclusion The levels of MDA and IL-1β in the synovial fluid were raised,while SOD was significantly decreased in acute gouty arthritis.Moderate and high-doses of probucol can effectively control acute gouty arthritis attack.The efficacy of high-dose probucol was equal to that of colchicines.
