Figure 6From: Removal of urothelium affects bladder contractility and release of ATP but not release of NO in rat urinary bladder Effect of substance P (5 μM) on ATP (A) and NO (B) release in intact and swabbed bladder strips. Substance P significantly increased ATP release (**P < 0.01) over the baseline in intact but not in swabbed preparations (P > 0.05). NO release was significantly increased both in intact and swabbed preparations to the same extent (**P < 0.01).Back to article page
