Pathomorphology of renal tissue in rats to evaluate tubulointerstitial fibrosis (Masson ×400). (a) Representative Masson’s trichrome stained sections. (b) Semiquantitative score of tubulointerstitial fibrosis for different groups. NC: normal control; DM: diabetic rats without drug treatment; TL: low-dose TGT (1 mg/kg/day); TM: medium-dose TGT (3 mg/kg/day); TH: high-dose TGT (6 mg/kg/day). versus NC group, versus DM group, versus TL group, and versus TM group.
