Popis: Aim: We investigated the effects of silodosin (selective (1A)-adrenoceptor antagonist) on erectile dysfunction (ED) in a rat model of bladder outlet obstruction.Methods: Adult male Sprague-Dawley rats (n=32) were divided into four groups: (i) sham-operated control; (ii) silodosin-treated (sham) control (0.1mg/kg/day); (iii) partial bladder outlet obstruction (PBOO); and (iv) silodosin-treated with PBOO. PBOO was induced by ligation of the urethra for 6 weeks. In vivo, erectile responses were monitored by evaluating ratios of intracavernosal pressure (ICP)/mean arterial pressure (MAP). Organ-bath studies were performed on corpus cavernosum (CC) strips. Penises were assessed at baseline for protein expression of neuronal nitric oxide synthase (nNOS) and Rho-associated protein kinase (ROCK2) by Western blot. Immunohistochemistry and Masson trichrome staining were performed for analysis of nNOS protein levels and tissue alterations.Results: The ratio of ICP/MAP was significantly decreased in obstructed rats (0.260.043, P
