Does neurogenic nitric oxide mediate relaxation of canine corpus cavernosum?
It appears that the relaxation induced by nerve stimulation is mediated solely by NO liberated from the nerve that activates soluble guanylate cyclase and increases the production of cyclic GMP in smooth muscle, whereas VIP does not play a role in the regulation of muscle tone under the experimental conditions used.
Venoplasty or dilatation of chronic total venous occlusion is a safe and effective technique, which allows for placement of transvenous leads.
