“In human cavernosum treated with thapsigargin (inhibitor of …+)-ATPase) in Ca(2+)-free medium, PMF suppressed the concentration-… human cavernosum to phenylephrine and a further suppression was found when SKF-96365 (a blocker of store-operated … and Y-27632 (inhibitor of Rho-kinase)), but not nifedipine, were added sequentially.”
“In normal Krebs solution with nifedipine (blocker of l-type Ca(2+) channels), or in Ca(2+)-free Krebs solution, PMF caused a further inhibition of human cavernosum contracted with phenylephrine.”
“ PMF caused … of phenylephrine precontracted human cavernosal strips, and this effect was slightly inhibited by N(G)-nitro-l-arginine, a nitric oxide synthase inhibitor, but not by ODQ (soluble guanylate cyclase inhibitor), TEA (tetraethylammonium, blocker of voltage-dependent K(+) channels) or glybenclamide (blocker of ATP-dependent K(+) channels).”
