Neurokinins activate TTX-insensitive rhythmic contractions of the rat isolated ureter. Field stimulation or capsaicin (1-3 uM) transiently inhibited the neurokinin-activated motility in controls but not capsain-pretreated (50 mg/kg sc) rats. The inhibitory action of field stimulation but not that of caspaicin was prevented by TTX. Thus a capsaicin-sensitive inhibitory innervation exists in the rat ureter.

Abstract
Neurokinins activate TTX-insensitive rhythmic contractions of the rat isolated ureter. Field stimulation or capsaicin (1-3 uM) transiently inhibited the neurokinin-activated motility in controls but not capsain-pretreated (50 mg/kg sc) rats. The inhibitory action of field stimulation but not that of caspaicin was prevented by TTX. Thus a capsaicin-sensitive inhibitory innervation exists in the rat ureter.File in questo prodotto:
