Sections of the colon of adult male mice. (AC) Mallory’s trichrome-stained sections (200x); collagen fibers (arrows). (A) Control group showing few collagen fibers, (B) DSS group showing numerous collagen fibers, (C) DSS+ AuNPs group showing some collagen fibers. (DF) Alcian blue-stained sections (200x); goblet cells (g). (D) Control group with abundant goblet cells, (E) DSS group with few goblet cells, (F) DSS+ AuNPs group with many goblet cells. (GI) Immune histochemical-stained sections for IL-17A (400x); brown positive cytoplasmic reactions (arrows).
