    Notes: Summary We found that large cells in the dorsal root and trigeminal ganglia contained glutamate-like immunoreactivity. Immunoreactive neurons were not detected in the superior cervical or pterygopalatine ganglia. These findings indicated that glutamate is a neurotransmitter or neuromodulator of large cells of sensory ganglia.

    Notes: Summary The distribution, origin and fine structure of substance P-like immunoreactive (SPI) nerve terminals in the facial nucleus of the rat were investigated by means of immunocytochemistry. SPI-terminals were concentrated in the intermediate and dorsal subnuclei of the facial nucleus. Hemi-transection of the brainstem just rostral to the facial nucleus or at the most caudal level of the medulla oblongata did not cause any change of SPI-terminals in the facial nucleus. Electrical destruction of the various parts of the medulla oblongata clearly demonstrated that SPI-terminals in the intermediate subnucleus were supplied contralaterally from the SPI-neurons in the dorsomedial part of the medullary reticular formation. Most of the SPI-terminals (85%) in the intermediate subnucleus of the facial nucleus were observed to make asymmetric synaptic contacts with large dendrites (mean diameter; 1.26 μm). It was supposed that the contact sites are located on proximal parts of the dendrite. A few SPI-terminals (6%) formed axo-somatic contacts with large perikarya filled with numerous cytoplasmic organelles.

    Notes: Summary We studied the distribution of fibers with leucine-enkephalin — like immunoreactivity (L-ENKI) in the medial preoptic area (MPO) of the rat, and the origins of such fibers, using indirect immunofluorescence and a combination of a retrograde tracer with immunocytochemistry that we have developed. These fibers were very dense throughout the rostro-caudal part of the MPO. The distribution was uneven with the highest density in the lateral part. Destruction of the arcuate nucleus, which contains a group of L-ENKI neurons, resulted in the marked reduction of these fibers in the ipsilateral MPO, suggesting that most of these fibers originate in this nucleus. This was also suggested by the fact that injection of biotin-wheat germ agglutinin into the MPO labelled many neurons in the arcuate nucleus ipsilaterally. Simultaneous staining with antiserum showed that some of these neurons are L-ENKI.

    Notes: Summary Histamine N-methyltransferase (S-adenosylmethionine: histamine N-methyltransferase, E.C. 2.1.1.8) was purified to homogeneity from rat kidney, and antibody was raised against it in guinea pigs. The antibody immunoprecipitated histamine N-methyltransferase. Immunofluorescent histochemical studies with anti-histamine N-methyltransferase antibody as the first antibody and goat antiguinea pig IgG conjugated with fluorescein isothiocyanate as the second, showed the presence of immunoreactive structures in the proximal tubules of rat kidney. The brain showed no immunoreaction with the antibody.
