Histology change in allografts and controls. A The Banff sums of renal structural damage in allografts and controls. Rats in the transplanted group developed a higher degree of renal interstitial fibrosis, tubulopathy, glomerulopathy and intimal proliferation. The Banff sum of scores in allografts was significantly higher than that in either LEW controls or F344 controls. B The percentages of interstitial fibrosis in allografts and controls (100 ×). There was no significant difference between the percentages of interstitial fibrosis of allografts and either F344 controls or LEW controls. C The quantity of interstitial mononuclear cells in allografts and controls (400 ×). The quantity of interstitial mononuclear cells in allografts significantly increased compared to that of either F344 controls or LEW controls. D The quantity of vascular SMCs in the cortex arteriolar wall of allografs and controls (× 400). The quantity of vascular SMCs in allografts was significantly increased compared to that of either F344 controls or LEW controls.
