We examined the effects of endothelium-dependent responses on coronary perfusion pressure (CPP) in isolated, blood-perfused neonatal pig hearts under conditions of controlled coronary flow. Baseline CPP was increased 8%-21% by the cyclooxygenase inhibitor indomethacin (10-100 microM), and 30%-92% by NG-monomethyl-L-arginine (L-NMMA, 10-100 microM), an(More)

Revascularization of the penis is indicated in those patients in whom peripheral arterial occlusion of the internal pudendal artery alone or in combination with the venous incompetence of the penis, was detected to be the cause of erectile dysfunction. The authors present the results of penile revascularization in 12 patients impotent after crushing pelvic(More)
The penile venous system plays an important role in the haemodynamics of erection. Failure of the venous occlusive mechanism leads to venous incompetence and impotence. The authors have examined the functional capacity of the penile venous system by dynamic pharmacocavernosometry in 31 patients with erectile dysfunction. This diagnostic tool enables to(More)
