    Notes: Summary The origins of calcitonin gene-related peptide immunoreactive (CGRPI) fibers in the cochlea were examined in rats. Parasagittal transection of the brain just medial to the principal sensory trigeminal nucleus resulted in the ipsilateral disappearance of CGRPI fibers in the cochlea, indicating that the origins of these fibers lie in the central nervous system. Next, we used a highly sensitive method combining retrograde tracing and immunohistochemistry to identify the origins of the CGRPI fibers in the cochlea. After injection of biotin-wheat germ agglutinin (b-WGA) into the cochlea, CGRPI neurons in the ipsilateral lateral superior olivary nucleus also contained b-WGA granules. These findings indicated tht CGRPI efferent fibers are major components of the olivocochlear bundle.

    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 The destruction of th central amygdaloid nucleus (Ce), which contains a large group of neurons with leucine-enkephalin (L-ENK)-like immunoreactivity (L-ENKI), resulted in a marked ipsilateral reduction of these fibers in the bed nucleus of the stria terminalis (BST) suggesting that L-ENKI neurons in the Ce project ipsilaterally to the BST. This was supported by the finding that injection of biotin-wheat germ agglutinin into the BST labeled many neurons in the Ce. Simultaneous staining with antiserum showed that some of these neurons are L-ENKI. The L-ENKI fibers from the Ce reach the BST via two pathways; one from the ventral amygdalofugal pathway (VA), which terminate in the ventral subdivision of the BST pars lateralis (BSTL), and the other from the stria terminalis (ST), which terminates in the lateral subdivision of the BSTL, because (1) accumulation of L-ENKI structures appeared in the axons of these two systems on the amygdaloid side, (2) transection or destruction of the ST alone caused only a slight reduction of ENKI fibers in the lateral subdivision of the BSTL ipsilaterally and (3) transection or destruction of VA alone markedly reduced the number of L-ENKI fibers in the ventral subdivision of the ipsilateral BSTL. Thus, the VA L-ENKI fiber system is the major source of L-ENKI fibers in the ventral subdivision, while the ST L-ENKI fiber system is a minor source of the L-ENKI fibers in the lateral subdivision. The presence of an intrinsic L-ENKI system in the BST which may innervate the lateral subdivision was also suggested.

    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 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 overall distribution of substance P-like immunoreactive (SPI) fibers in the rat urinary bladder was examined by means of frozen sections and whole mount preparations. Two types of SPI fibers entered the urinary bladder from the neck; one forming thick fiber bundles and the other around the blood vessels. These SPI fiber bundles branched into several thinner segments which often project many collaterals to the smooth muscle and submucosal layers. In the smooth muscle layer, single SPI fibers were seen running parallel to both longitudinal and circular muscle bundles. They appeared to be evenly distributed in the smooth muscle layer. SPI fiber bundles located in the circular muscle layer dissociated SPI fibers which entered the submucosal layer, where they directed to the epithelium and formed a meshwork just beneath it. SPI fibers often left the meshwork to enter the epithelium where abundant arborization of fine SPI fibers was seen. The density of SPI fibers in the submucosal layer and epithelium was not even. The highest density was identified in the neck and the trigonum area.

    Notes: Summary We studied the three-dimensional distribution of structures with calcitonin gene-related peptide-like immunoreactivity (CGRPI) in the rat stomach and duodenum, including the origins of these structures, using indirect immunofluorescence in both muscle strips and frozen sections. There was a very dense meshwork of CGRPI fibers in the circular and longitudinal muscle layers, and also in the myenteric and submucous plexuses of the stomach and duodenum. No CGRPI neurons were seen in the stomach, even in rats treated with colchicine; in the duodenum, there was a group of CGRPI cells in the myenteric and submucous ganglia. No regional differences were seen in the stomach and duodenum. We found by experimental manipulations that CGRPI fibers in the stomach were exclusively extrinsic in origin; some of such fibers in the duodenum were intrinsic in origin, though most were supplied by CGRPI cells outside the duodenum.

    Notes: Summary The origin of neurotensin-like immunoreactive (NTI) fibers in the central amygdaloid nucleus (AC) in the rat was examined using indirect immunofluorescence and retrograde tracing combined with immunocytochemistry. Destruction of the external subdivision of the lateral parabrachial nucleus, which contains a group of NTI neurons, resulted in a marked reduction of these fibers in the ipsilateral AC, which suggests that most of these fibers are of extrinsic origin. This was also supported by the finding that injection of fast blue dye into the AC labeled many neurons in the external subdivision of the lateral parabrachial nucleus ipsilaterally, and that simultaneous treatment with antiserum against NT stained some of these neurons. Subsequent immunohistochemical staining of alternate sections revealed that many of these NTI neurons were also labeled by calcitonin gene-related peptide antiserum.

    Notes: Abstract The small amplitude limit of the time-dependent density-matrix theory, which is an extension of the time-dependent Hartree-Fock theory, is presented. Its relation to other theories i.e. the random phase approximation (RPA), the second RPA and the shell model is discussed. It is found that the small amplitude limit is a generalization of these theories.

    Notes: Summary Rat calcitonin gene related peptide (CGRP) and salmon calcitonin (CT) stimulated adenylate cyclase activity in a dose-dependent manner in the rat diaphragm and in the kidney. The ED50 value of rat CGRP was lower and that of salmon CT was higher in the diaphragm than in the kidney. These results suggest that CGRP stimulates adenylate cyclase activity in the striated muscle by reacting with sites distinct from the site in the kidney.
