Localization of vasoactive intestinal polypeptide in penile erectile tissue and in the major pelvic ganglion of the rat.

摘要: Abstract Vasoactive intestinal polypeptide was localized by immunocytochemical techniques in the major pelvic ganglion and penile erectile tissue of rat. fibers were concentrated crura with density innervation decreasing distally. The helicine arteries very densely innervated while fewer surrounded deep artery penis. Intrinsic smooth muscle cavernous bodies received a moderate supply vasoactive immunoreactive fibers. Dorsal vascular structures, including dorsal vein cell found ganglion, on one end ganglion. Rectrograde studies dye injected into indicated that neurons projected to Combined immunofluorescent showed all dye-labeled for polypeptide. It is concluded beds penis rat are extent related occurrence muscle. Neurons probably main source
