Localization of substance P, calcitonin gene related peptide and galanin in the nerve fibers of porcine cystic ovaries

In a previous study, we showed that both the noradrenergic and cholinergic component of ovarian innervation is markedly changed in porcine cystic ovaries. The present study is aimed at elucidating the distribution pattern of substance P- (SP), calcitonin gene related peptide CGRP- and/or galanin (GA...

description In a previous study, we showed that both the noradrenergic and cholinergic component of ovarian innervation is markedly changed in porcine cystic ovaries. The present study is aimed at elucidating the distribution pattern of substance P- (SP), calcitonin gene related peptide CGRP- and/or galanin (GAL)-containing nerve fibers within porcine cystic ovaries. The <i>status polycysticus</i> was induced by dexamethasone phosphate disodium salt i.m. injections performed from the 7<sup>th</sup> until the 21<sup>st</sup> day of the first studied estrous cycle. During the same period of time, gilts of the control group received saline. All animals were slaughtered on the expected 11<sup>th</sup> day of the second studied estrous cycle, and their ovaries were collected. When compared to control gonad, a distinct difference in the distribution pattern and the density of SP-, CGRP- and/or GAL-immunoreactive (GAL-IR) nerve fibers was observed. Thus, unlike in the control gonad, SP- and/or CGRP-IR perivascular nerve fibers were found to supply medullar blood vessels of polycystic ovary. Furthermore, the number of GAL-IR nerve fibers contributing to the ground plexus in polycystic ovaries was higher than that observed in the control gonads. Thus, as may be judged from the profound changes in the distribution pattern of differently chemically coded afferent terminals within polycystic gonads, it appears possible that neuropeptides released from these terminals may take part in the etiopathogenesis of this disorder.
