Table 1.
Potency of carbachol (CCh) and isoprenaline (IPNA) in transverse (Tr) and longitudinal (Lg) detrusor strips from control and Tianma-treated rats. CCh-induced contractions and IPNA-induced relaxations of urothelium-intact (+UE) and urothelium-denuded (−UE) strips were examined. Potency is expressed as the logarithms of the CCh or IPNA concentration achieving 50 % maximal efficacy. * denotes P < 0.05 vs. control.
