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.

Mimecan belongs to a family of leucine-rich proteoglycans that are secreted into the extracellular matrix. In order to investigate the function of mimecan, the coding region of mimecan was amplifed from a human pituitary cDNA by PCR and the recombinant prokaryotic expression vector pGEX-M was constructed. The vactor was transformed into E.coli BL21(DE3)and the GST-M fusion protein of 38 Kd was ecpressed in the bacteria under induction of IPTG. After purification, the fusion protein was infucted into New Zealand rabbits to prepare polyclonal antibody. The antibody was tested by Western blotting for their specificity and sensitivity. Using the antibody it was found the mimecan was expressed highly in certain types of human pituitary tumor tissues. These results make it possible for studying the biological function of mimecan.
