Abstract
Gout is a rheumatic disease that is manifestated by an intense inflammation secondary to monosodium urate crystal deposition in joints. In the present study, we assessed the effect of 6-shogaol (isolated active principle from ginger) on monosodium urate crystal-induced inflammation in mice; an experimental model for gouty arthritis and compared it with that of the non-steroidal anti-inflammatory drug, indomethacin. Paw volume and levels/activities of lysosomal enzymes, lipid peroxidation, anti-oxidant status and inflammatory mediator TNF-α were determined in control and monosodium urate crystal-induced mice. The levels of β-glucuronidase and lactate dehydrogenase were also measured in monosodium urate crystal-incubated polymorphonuclear leucocytes (PMNL) in vitro. The levels of lysosomal enzymes, lipid peroxidation, and inflammatory mediator tumour necrosis factor-α and paw volume were increased significantly and the activities of anti-oxidant status were in turn decreased in monosodium urate crystal-induced mice, whereas these changes were reverted to near normal levels upon 6-shogaol administration. In vitro, 6-shogaol reduced the level of β-glucuronidase and lactate dehydrogenase in monosodium urate crystal-incubated polymorphonuclear leucocytes in concentration dependent manner when compared to control cells. The present results clearly indicated that 6-shogaol exerted a strong anti-inflammatory effect and can be regarded as useful tool for the treatment of acute gouty arthritis. © 2009 Elsevier Ltd.
