Figure 4. Effects of Danshen injection on morphological changes in kidneys.

Figure 4

Representative microscopic photographs of H&E, PAS and Masson’s trichrome stained kidney tissue sections (magnification 400×). Kidneys were obtained from the control (A), iron overload (B), DFO (C), H-Danshen (D) and L-Danshen (E) groups. Scores for glomerular lesions (F) and tubulointerstitial lesions (G) are shown. Black arrows indicate histological changes of glomerular cells, and the green arrows indicate histological changes of tubulointerstitial cells. Data are presented as means ± S.E.M of 15 animals per group. **P<0.01, compared with iron overload group; ##P<0.01, compared with control group.
