    Abstract:
    The morphological distribution of the nerve terminals containing LH-RH in the hypothalamus especially in the median eminence of the proestrus female rat was demonstrated by immunohistochemistry, using FITC and peroxidase antibody. The terminals containing LH-RH were classified into four groups on the topographic relationship. LH-RH nerve processes terminated mainly in the infurdibular radix within an elliptical zone surrounding the bases of the infundibular recessus. The heaviest concentration of LH-RH terminals immunohistochemically demonstrated lay on each side of the region extending from the dorsal part of tuberoinfundibular sulcus to the lateral part of the external layer of the superior labium of the infundibulum. We were unable to detect any neuronal soma with the immunoreactivity to LH-RH in the hypothalamic gray matter. The distributional patterns of LH-RH, GH-RIH and monoamine in the median eminence as well as their relationships were briefly discussed.
