    Description / Table of Contents: Durch radikalische Polymerisation von Acrylnitril in Gegenwart von Cer(IV)-salzen und Amylose wurden außer größeren Mengen von Homopolyacrylnitril Pfropfpolymerisate von Polyacrylnitril an Stärke erhalten.Für die Polymerisationsgeschwindigkeit Rp, die in Dimethylsulfoxyd größer ais in Wasser war, wurden folgende Gleichungen aufgestellt: Hierin stellen A, B und C Konstanten, [S], [M] und [TCe4+] die Konzentrationen der Stärke, des Acrylnitrils und der Cer(IV)-verbindungen dar. Die Unterschiede der beiden Formeln werden erörtert.
    Notes: A graft copolymer of polyacrylonitrile with starch was obtained by radical polymerization of acrylonitrile in the presence of ceric salt and amylose, accompanied by a considerable amount of homopolymer of acrylonitrile. The rate of polymerization was faster in dimethyl sulfoxide than in water. The following empirical rate equations were presented. where A, B and C are constants and [S], [M] and [TCe4+] are the concentration of starch, acrylonitrile and total ceric compounds respectively. The differences between the two equations were discussed.

    Description / Table of Contents: Poly-3-O-methacryloyl-D-glucose (PMG) wurde durch Hydrolyse des durch radikalische Polymerisation von 3-O-Methacryloyl-1.2,5.6-diisopropyliden-D-glucose (MDG) gewonnenen Polymerisates (PMDG) hergestellt. MDG wurde durch Reaktion von 1.2,5.6-Diisopropyliden-D-glucose mit Methacrylsäurechlorid synthetisiert. PMG war in Wasser oder Dimethylsulfoxyd löslich, jedoch in anderen organischen Lösungsmitteln unlöslich. Es reduzierte FEHLINGsche Lösung und war optisch aktiv. PMG schmeckte leicht süßlich.MDG wurde mit Acrylnitril copolymerisiert. Das so gewonnene Copolymerisat wurde mit einer sauren Lösung von Zinkchlorid hydrolysiert. Das hydrolysierte Copolymerisat besaß reduzierende Eigenschaften und war in Dimethylformamid und in wäßriger ZnCl2-Lösung löslich. Durch Erhitzen mit einem wasserlöslichen Farbstoff ließ es sich anfärben.
    Notes: 3-O-methacryloyl-1,2,5,6-diisopropylidene-D-glucose (MDG) was synthesized from 1,2,5,6-diisopropylidene-D-glucose and methacryloyl chloride. It was polymerized to PMDG using azo-bis-isobutyronitrile as initiator. Poly-3-O-methacryloyl-D-glucose (PMG) was prepared by hydrolysis of PMDG. PMG was soluble in water or dimethyl sulfoxide but insoluble in other organic solvents. It reduced FEHLING's solution and showed an optical activity. PMG tasted a little sweet.MDG was copolymerized with acrylonitrile. The copolymer was hydrolyzed in acidic solution of ZnCl2. The hydrolyzed copolymer showed a reducing power, and was soluble in DMF or aqueous ZnCl2 solution. It was well dyed by water soluble dyes.

    Prostaglandin D2 as a mediator of allergic asthma (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-03-17
    Description: Allergic asthma is caused by the aberrant expansion in the lung of T helper cells that produce type 2 (TH2) cytokines and is characterized by infiltration of eosinophils and bronchial hyperreactivity. This disease is often triggered by mast cells activated by immunoglobulin E (IgE)-mediated allergic challenge. Activated mast cells release various chemical mediators, including prostaglandin D2 (PGD2), whose role in allergic asthma has now been investigated by the generation of mice deficient in the PGD receptor (DP). Sensitization and aerosol challenge of the homozygous mutant (DP-/-) mice with ovalbumin (OVA) induced increases in the serum concentration of IgE similar to those in wild-type mice subjected to this model of asthma. However, the concentrations of TH2 cytokines and the extent of lymphocyte accumulation in the lung of OVA-challenged DP-/- mice were greatly reduced compared with those in wild-type animals. Moreover, DP-/- mice showed only marginal infiltration of eosinophils and failed to develop airway hyperreactivity. Thus, PGD2 functions as a mast cell-derived mediator to trigger asthmatic responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsuoka, T -- Hirata, M -- Tanaka, H -- Takahashi, Y -- Murata, T -- Kabashima, K -- Sugimoto, Y -- Kobayashi, T -- Ushikubi, F -- Aze, Y -- Eguchi, N -- Urade, Y -- Yoshida, N -- Kimura, K -- Mizoguchi, A -- Honda, Y -- Nagai, H -- Narumiya, S -- New York, N.Y. -- Science. 2000 Mar 17;287(5460):2013-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Kyoto University Faculty of Medicine, Kyoto 606-8501, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10720327" target="_blank"〉PubMed〈/a〉
