Fig. 3. Effects of diacetylchrysin on formation of collagen fibers in glomeruli (A) and renal tubules (B). The db/db mice were supplemented with 10 mg/kg diacetylchrysin for 10 weeks. The db/m mice were employed as control animals. Glomerular and tubular fibrosis in db/db mouse kidneys was observed by Masson’s trichrome staining (A and B). The collagen fibers were stained in blue. Each photograph is representative of 4 mice. Magnification: 200-fold.
