    Abstract:
    The immunohistochemical localization of luteinizing hormone-releasing hormone (LHRH) was studied in paraffin and vibratome-sectioned tissue from adult female hamsters that were treated neonatally with monosodium glutamate (MSG) or hypertonic saline. There appeared to be a reduction in LHRH-positive fibers in the median eminence of animals with an MSG-induced lesion of the arcuate nucleus in paraffin-embedded tissue. However, when unembedded tissue was cut on a vibratome, the distribution of LHRH-positive fibers and perikarya was similar in both groups of animals. Fibers were seen coursing through the periventricular area and lateral hypothalamus to the median eminence. In addition, LHRH-positive fibers were seen in the organum vasculosum of the lamina terminalis, subfornical organ, septal and preoptic areas, fasciculus retroflexus, habenular complex, and several regions in the basal forebrain. Animals that were pretreated with colchicine had LHRH-positive perikarya in the medial habenular nucleus, diagonal band of Broca, and the medial olfactory tract.
