    Notes: Abstract We demonstrate the existence of nerve fibers possessing substance P (SP) and calcitonin gene-related peptide (CGRP) immunoreactivity in the mouse cervical ventral roots. The distribution of the SP and CGRP fibers was similar, but CGRP fibers were generally more numerous. Both types entered the ventral pia mater or formed hairpin loops, but they did not enter the spinal cord directly through these roots. SP and CGRP fibers in the ventral roots were thin and had many varicosities. We suggest that these SP and CGRP fibers are involved not only in a sensory mechanism, but also in other functions, via the release of SP and CGRP from varicosities in the ventral roots.

    Notes: Summary The distribution pattern of serotonin (5HT) in the pancreas was studied immunohistochemically by using a 5HT monoclonal antibody in various vertebrates including the eel, bullfrog, South African clawed toad, turtle, chicken, mouse, rat, guinea-pig, cat, dog and human. In all species examined, except the bullfrog, 5HT-like immunoreactivity was observed in nerve fibers, in endocrine cells, or in both. Positive nerve fibers were found in the eel, turtle, mouse, rat and guinea-pig. These fibers ran mainly along the blood vessels and partly through the gap between the exocrine glands. In the eel and guinea-pig, positive fibers invaded the pancreatic islet. Occasionally, these positive fibers were found adjacent to the surface of both exocrine and endocrine cells, suggesting a regulatory role of 5HT in pancreatic function. 5HT-positive endocrine cells were observed in the pancreas of all species except for the bullfrog and rat. In the eel and in mammals such as the mouse, guinea-pig, cat, dog and human, 5HT-positive cells were mainly observed within the pancreatic islet. In the South African clawed toad, turtle and chicken, the positive cells were mainly in the exocrine region. The present study indicates that the distribution patterns of 5HT in the pancreas varies considerably among different species.

    Effects of osmotic pressure and adsorption on ultrafiltration of ovalbumin (1990)

    Notes: The influence of osmotic pressure and solute adsorption on permeate flux during ultrafiltration of a solute that forms a gel-like layer on membrane surfaces was investigated. Ovalbumin solutions were ultrafiltrated using three different kinds of membranes, polyolefine, polysullfone, and polyacrylonitrile. Flux data were analyzed by three conventional models: gel polarization, osmotic pressure, and resistance in series.The experimental data were in conflict with all conventional models. Data analysis suggested that the main factors which influence permeate flux decline were osmotic pressure increase at the membrane surface and resistance caused by solute adsorption.A new model, which takes into account both osmotic pressure and resistance due to solute adsorption, is proposed. Permeate flux declines observed in the experiments fit this model quite precisely. The gel layer that forms on the membrane surface has little influence on permeate flux and can be neglected.

    Notes: From time to time, A.I.Ch.E. Journal presents translations of certain technical articles written by our Japanese colleagues in their own language. These translations are made by Kenzi Etani, who received his B.S. in chemical engineering in 1953 at the Tokyo Institute of Technology and his M.S. in 1955 at M.I.T. He is associated with Stone & Webster and is an associate member of American Institute of Chemical Engineers. He is also a member of the Society of Chemical Engineers, Japan, and the Japan Oil Chemists' Society. His offer to help break down the language barrier is acknowledged.Abstracts, notation, literature cited, tables, and figure captions not published here appear in English in the original paper. No figure will be reproduced in these translations.The following article was published in Chemical Engineering (Japan), 21, pages 17-25 (1957).

    Endothelin: a novel peptide in the posterior pituitary system (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-01-26
    Description: Endothelin (ET), originally characterized as a 21-residue vasoconstrictor peptide from endothelial cells, is present in the porcine spinal cord and may act as a neuropeptide. Endothelin-like immunoreactivity has now been demonstrated by immunohistochemistry in the paraventricular and supraoptic nuclear neurons and their terminals in the posterior pituitary of the pig and the rat. The presence of ET in the porcine hypothalamus was confirmed by reversed-phase high-pressure liquid chromatography and radioimmunoassay. Moreover, in situ hybridization demonstrated ET messenger RNA in porcine paraventricular nuclear neurons. Endothelin-like immunoreactive products in the posterior pituitary of the rat were depleted by water deprivation, suggesting a release of ET under physiological conditions. These findings indicate that ET is synthesized in the posterior pituitary system and may be involved in neurosecretory functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshizawa, T -- Shinmi, O -- Giaid, A -- Yanagisawa, M -- Gibson, S J -- Kimura, S -- Uchiyama, Y -- Polak, J M -- Masaki, T -- Kanazawa, I -- New York, N.Y. -- Science. 1990 Jan 26;247(4941):462-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, University of Tsukuba, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2405487" target="_blank"〉PubMed〈/a〉
