Proteinuria measured every 2 wk throughout the duration of the study. A: sham rats had increased proteinuria when given nicotine in the drinking water, which was partially prevented by cyclooxygenase (COX)-2 inhibition [*P < 0.05 vs. the Sham group; #P < 0.05 vs. sham-operated rats given nicotine (ShamNic group)]. B: the administration of nicotine worsened proteinuria in 5/6 nephrectomy (5/6Nx) rats but was prevented by COX-2 inhibition. In rats with 5/6Nx and tap water, COX-2 inhibition worsened proteinuria during the last 4 wk of the study [*P < 0.05 vs. the 5/6Nx group; #P < 0.05 vs. 5/6Nx rats given nicotine (5/6NxNic group)]. 5/6NxNicNS, 5/6Nx rats given nicotine and NS-398; 5/6/NxNS, 5/6Nx rats given NS-398; ShamNicNS, sham-operated rats given nicotine and NS-398.
