    Intracellular Na+ and Ca2+ activities in aortic smooth muscle cells from spontaneously hypertensive rats (1982)
    Springer
    Research in experimental medicine 181 (1982), S. 221-224

    ISSN: 1433-8580

    Notes: Summary Elevations of intracellular Na+ and Ca2+ in essential hypertension have up to now only been demonstrated in blood cells. Therefore, intracellular Na+ and Ca2+ activities were determined in cultured aortic smooth muscle cells from nine spontaneously hypertensive rats of the Münster strain and from nine normotensive Wistar rats. Intracellular ion activities were determined by ion-selective electrodes. In muscle cells from spontaneously hypertensive rats intracellular Na+ activity was markedly elevated (P〈0.01), whereas intracellular Ca2+ was not significantly different. This points to the preponderance of genetic causes for the elevation of intracellular Na+, whereas the disturbances in cellular Ca2+ metabolism may additionally require humoral factors to become manifest.

    Intracellular Na+ and Ca2+ in aortic smooth muscle cells after enzymatic isolation in spontaneously hypertensive rats (1983)
    Springer
    Research in experimental medicine 183 (1983), S. 129-132

    ISSN: 1433-8580

    Notes: Summary In aortic smooth muscle cells from spontaneously hypertensive and normotensive rats, which were separated from the blood vessels by enzymatic digestion, intracellular Na+ and Ca2+ activities were measured. The determinations were made by ion-selective electrodes. In smooth muscle cells from spontaneously hypertensive rats intracellular Na+ and Ca2+ activities were elevated as compared to cells from normotensive rats (P〈0.001 for Na+ andP〈0.01 for Ca2+). Since in cultured aortic smooth muscle cells from spontaneously hypertensive rats intracellular Ca2+ is known to be not significantly increased, primarily humoral factors may account for the changes in intracellular Ca2+ reported.

    Flexirubin-type pigments in Flavobacterium (1980)
    Springer
    Archives of microbiology 126 (1980), S. 291-293 
    Details
    ISSN: 1432-072X
    Keywords: Flexirubin-type pigments ; Flavobacterium ; Taxonomy of flavobacteria ; Chemosystematic markers ; Flexibacteria
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In an organism (strain C 1/2 from Dr. P. R. Hayes, Leeds) regarded as a typical representative of the genus Flavobacterium, flexirubin-type pigments have been identified. The Flavobacterium pigments contain structural elements of both, the pigments of the genus Flexibacter and the pigments of the genus Cytophaga. As flexirubin-type pigments seem to have a rather restricted distribution among bacteria, and have formerly proved to be useful chemosystematic markers for the flexibacteria, this new observation may indicate that there is a relatively close phylogenetic relationship between this type of flavobacteria and the Cytophaga-Flexibacter group.

    On the origin of the branched alkyl substituents on ring B of flexirubin-type pigments (1982)

    Topics: Biology
    Notes: Abstract Studies with radioactive leucine, isoleucine, valine and acetate showed that in Flavobacterium spec. strain C1/2 leucine can function as the precursor of the terminally branched alkyl substituents in flexirubin-type pigments.
