Tolvaptan Improves Contrast-Induced Acute Kidney Injury

Figure 5

Effects of tolvaptan on the Nrf2/Keap-1/HO-1 pathway-related proteins. The kidney tissues of each group of rats were collected, the expression of Nrf2, Keap-1, and HO-1 proteins was detected by western blot, and the protein bands were analyzed in grayscale. Data are presented as . , , and vs. control group; ## vs. CIN group; && vs. CIN + TOL group.
