Fig. 6From: Chelidonic acid ameliorates atopic dermatitis symptoms through suppression the inflammatory mediators in in vivo and in vitroEffect of CA on COX-2 and iNOS expression in LPS-stimulated peritoneal macrophages. Cells (5 × 106 cell/well) were pretreated with various concentrations of CA for 1 h and subsequently stimulated with LPS (200 ng/mL) for 24 h. A and C COX-2 and iNOS expression was determined by western blotting analysis. B and D The relative COX-2 and iNOS levels were determined by densitometry. Values are the mean ± S.D. of duplicate determinations from three separate experiments (#p < 0.05 vs. un-stimulated cells, *p < 0.05 vs. LPS-stimulated cells)Back to article page
