摘要

An immunohistochemical study of the pig pineal gland was carried out using polyclonal rabbit antiserum raised against substance P (SP). The pineal glands were taken from the newborn, 21-day- and 7-month-old female pigs. Immunoreactive nerve fibers were observed in the pineal gland as well as in the posterior commissure and habenular areas. The bundles of SP-immunoreactive fibers were also seen in the subependymal layer of the pineal tissue. The single SP-immunoreactive nerve fibers and few small bundles of nerve fibers were located with equal density throughout the pineal gland, in the connective tissue septa and in the parenchyma. SP-immunoreactive cell bodies were observed in the medial habenular nucleus. The obtained results point to this nucleus as one of the central sources of SP innervation in the pig pineal gland. The study did not show any differences in the distribution and the density of SP-immunoreactive nerve fibers between newborn, 21-day- and 7 month-old pigs.
