Figure 3. Imperatorin inhibited IL-1β-induced NO production and expression of iNOS in human cartilage explants.

Figure 3.

(A) iNOS expression in human OA cartilage explants treated with IL-1β in the presence or absence of Imperatorin was determined by IHC (20X magnification). (B) Quantification of IHC data. For each explant, 5 sections were scored (N=5). (C) Supernatants of the explants were collected to estimate the levels of NO. The values are mean ± SD of three independent experiments. (** p≤0.005). The values are mean ± SD of three independent experiments.
