Detection of catecholamine and luteinizing hormone-releasing hormone (LH-RH) containing nerve endings in the median eminence and the organon vasculosum laminae terminalis by fluorescence histochemistry and immunohistochemistry on the same microscopic sections.
Distribution of catecholamine (CA) and LH-RH nerve endings in the median eminence (ME) and the organon vasculosum laminae terminalis (OVLT) of the rat was investigated by application of fluorescence histochemistry and immunohistochemistry on the same sections of the tissue. In the ME, those two kinds of endings coexisted in the lateral portion of the middle part of ME, and in the wall of tuberoinfundibular sulcus, where they might be considered to have functional correlation. In the OVLT they were also distributed in fairly near distance, but they were not so closely associated as observed in the ME.
