Abstract:
The experiments were performed on 5 sexually immature and 6 mature pigs. The segments of vagina were collected and then cut by means of a freezing microtome. The adrenergic nerves were detected according to Torre and Surgeon's (1976) glyoxylic method, and examined under a fluorescent microscope. Presence of AChE-positive fibers was detected using Karnovsky-Roots (1964) method. Both the adrenergic and the AChE-positive fibres were found in all layers of vaginal and around the blood vessels. As results from the studies, pig vagina is much more innervated with AChE-positive nerves than with adrenergic ones. Distribution pattern of these fibers is similar in all layers of the vagina. No differences were found between innervation of vagina in sexually mature and immature pigs.
