The ratio of bladder weight to body weight of sham group, OAB model group, tolterlodine treated group, capsazepine group (intravesical instillation at 10uM for 30 min before cystometrography), SQW treated group (treated with SQW at 293, 585, 1170 mg/kg/day). Values are expressed as mean ± SEM. ★★ = P < 0.01 for comparisons between the OAB model group vs sham group. ## = P < 0.01 for comparisons between the SQW treated group OAB model group
