    Activity of Carbonic Anhydrase in Relation to Gastric Secretion (1940)
    [s.l.] : Nature Publishing Group
    Nature 146 (1940), S. 651-652 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IT has been shown recently by Davenport1 that the gastric mucosa of mammals is very rich in carbonic anhydrase, which seems to be localized in the parietal cells. According to Davenport, this observation together with some other considerations suggested the possibility that ...

    Notes: [Auszug] THE importance of cozymase as a fundamental constituent of certain respiratory processes in the living cell is now well established. It is known that cozymase is necessary for the activity in animal tissues of specific dehydrogenases oxidizing alcohol, lactate, malate, triosephosphate, etc. Its ...

    Notes: [Auszug] WE have shown in earlier papers1 that in the presence of glucose or of pyruvate and under aerobic conditions brain tissue, whether sliced or minced, synthesizes acetylcholine. In the absence of such substrates, little or no synthesis takes place. Since it is well known from the ...

    Notes: [Auszug] WE recently reported1 the results of temperature measurements made by means of very fine quartz-coated platinum wires in the flame gases resulting from the combustion of hydrocarbon-air mixtures in a specially constructed burner. From these measurements estimates were made of the ...

    Notes: [Auszug] MANY substances have been found to have anti-thyroid activity in the vertebrate body, some of them natural constituents of the body. But it has never been clear to what extent these substances exert their antithyroid properties in normal life. In this letter we report some results which have ...
