Oral application of LSW-ET decreased the nanoDEN-induced COX-2 expression in mice. (a) Expression of COX-2 by immunohistochemistry. Scale bar, 50 μm. (b) Quantitative expression of COX-2 determined by immunohistochemistry. (Results were expressed as the mean ± SEM. , P < 0.05; , P < 0.01; , P < 0.001; †, P > 0.01, compared with the control group. #, P < 0.05; ##, P < 0.01; ###, P < 0.001; ‡, P > 0.01, respectively, compared with the nanoDEN group.)
