Effect of kirenol on IL-1β–stimulated inflammatory cytokines in chondrocytes. A, B The protein expression and quantification analysis of iNOS and COX-2 on chondrocytes treated as above were measured by western blot. C, D The protein level of PGE2, NO, TNF-α and IL-6 production on chondrocytes treated as above were assessed by ELISA. The data presented are the means ± S.D. *p < 0.05, and **p < 0.01, one-way AVOVA, n = 6
