METHODS: The experiment included four groups of rats (n = 5 each group): (1) Sham group, (2) SNx group, (3) SNx + L-arg group, and (4) Sham + L-arg group (L-arg 1% in drinking water). Parameters related with CRG and early tubulointerstitial expression of ECM and alpha smooth muscle actin (alphaSMA) were evaluated by immunohistochemistry at day 30. The survival rate and the extent of renal scarring in the rats were observed at day 120. RESULTS: L-arg significantly increased the early CRG of SNx rats as determined by the wet kidney weight (P展开更多
