Fig. 3From: Chitosan oligosaccharide inhibits skull resorption induced by lipopolysaccharides in micea and b. Mouse calvarial bone resorption was examined with TRAP staining. PBS group; LPS group; LPS + 0.005% LMCOS group; LPS + 0.05% LMCOS group; LPS + 0.5% LMCOS group; c. Quantitative analysis of TRAP-positive cells (**p < 0.05, *p < 0.05). The arrows represented bone resorption pits (TRAP, × 10)Back to article page
