Effect of carbachol (50 μM) on ATP (A) and NO (B) release in intact and swabbed bladder strips. Carbachol significantly increased ATP release over the baseline in intact (*P < 0.05) but not in swabbed preparations (P > 0.05). Similarly NO release was significantly higher in intact preparations but did not change in swabbed strips (P > 0.05).
