Curcumin pretreatment declined M1/M2 macrophage ratio in colon. a The mRNA levels of iNOS and Fizz-1 were detected by qRT-PCR. iNOS and Fizz-1 are the markers of M1 and M2. b Curcumin led to the ratio of iNOS/Fizz-1 declined. c Representative images of CD11c staining (left sections) and CD163 staining (right sections) in colonic tissue from each group. Curcumin pretreatment decreased the areas of CD11c and CD163 staining
