Task: Question Generation
Input (English): We investigated the pharmacological effect of TRPV1 antagonists in anesthetized rodent models of bladder function.', 'The TRPV1 antagonists JNJ17203212 and JYL1421 were evaluated in the anesthetized rat volume induced micturition reflex model. JNJ17203212 was further evaluated in this model in capsaicin (Sigma) desensitized rats, and in rat capsaicin and mouse citric acid models of irritant induced detrusor overactivity.', 'Systemic JNJ17203212 and JYL1421 administration in the anesthetized rat volume induced micturition reflex model resulted in an increased micturition threshold volume. JNJ17203212 also decreased bladder contraction amplitude but JYL1421 had no effect. Capsaicin desensitization significantly increased baseline micturition threshold volume and decreased bladder contraction amplitude in the volume induced micturition reflex model compared to those in sham treated controls and JNJ17203212 produced no further effect after capsaicin desensitization. JNJ17203212 was also effective in 2 models of irritant induced detrusor overactivity, preventing the decrease in micturition threshold volume and the increase in bladder contraction amplitude observed with intravesical instillation of 10 microM capsaicin, and the decreased voiding interval induced by intravesical citric acid.
Output (English): Does selective pharmacological blockade of the TRPV1 receptor suppress sensory reflexes of the rodent bladder?
