Abstract:
Objective：To confirm the effects of the macrophages and NO in the fibrosis formation of transplanted kidneys with chronic rejection. Methods：The quantitive immunohistochemistry was employed to observe the changes of relative quantitiy of macrophages, NO, collagen Ⅲ andⅣ， and to reveal the association between the increases of macrophages， NO， histopathologic damages, deposition of collagen Ⅲ and Ⅳ, finally, to infer the roles of the macrophages and NO in the fibrosis formation of transplanted kidneys with chronic rejection. Results: The macrophages accumulated and increased in the glomeruli, the tubules and the intersiticia tissue of kidneys, which was companied by the increased expression of collagen Ⅲ and Ⅳ during the early and middle stages. However, the macrophages and NO could not be detected, which was companied by the decreased deposition of collagen Ⅲ and Ⅳduring the advanced stage. There were significant differences between the 3 types(glomerulus disease type,blocking vessel type and intersticial sclerostic type) (P<0.05 or P<0.01). Conclusion：The increase of macrophages and the NO may closely interrelated with the fibrosis formation in transplanted kidneys with chronic rejection.
