Effect of YQQRG treatment on renal expression of IL-1β. The inflammatory cytokine IL-1β was observed by immunohistochemistry assay (A), along with its gene transcription examined by real-time PCR in the renal cortex (B and C). Rats in the PAN + YQ group received daily oral gavage of YQQRG. Rats in the sham and PNA groups received the same volume of vehicle (distilled water). 10D, 10 days after PAN injection; 15D, 15 days after PAN injection. Data are presented as mean ± SD values for each group of 3 animals. *P < 0.05 and **P < 0.01 compared to sham group, respectively. #P < 0.05 and ##P < 0.01 compared to PAN group, respectively.
