Methods: Twenty-four Kkay mice were divided into three groups(n=8):diabetes group,methionine-diet group,folic acid and vitamin B12 treatment group. C57Bl/6 mice were used as controls(C57). Four months later,the mice were sacrificed and their serum levels of Hcy,folic acid and vitamin B12 were measured by fluorescence polarization immunoassay. Pathological changes in kidneys were examined with the periodic acid schiff method with periodic acid-silver methenamine staining under electron microscope. Expression of MMP-9 protein or mRNA was detected by RT-PCR with immunohistochemical staining. Results: Different morphological changes of DN were found in Kkay mice.
