    Apamin, a nonspecific antagonist of smooth muscle relaxants (1980)
    Springer
    Naunyn-Schmiedeberg's archives of pharmacology 311 (1980), S. 105-107 
    Details
    ISSN: 1432-1912
    Keywords: Apamin ; noradrenergic inhibitory nerves ; ATP ; smooth muscle

    Topics: Medicine
    Notes: Summary Apamin, a peptide of bee venom, was shown to inhibit the relaxant responses of guinea-pig taenia caeci to ATP, noradrenaline, adenosine and, less effectively, to stimulation of noradrenergic inhibitory nerves. Thus apamin acts nonspecifically and, contrary to the suggestion of Vladimirova and Shuba (1978), the fact that inhibitory responses due to nerve stimulation and ATP are blocked by the toxin does not allow conclusions as to the possible transmitter role of ATP in these nerves.

    Thermal desorption-possibilities and limitations (1983)
    Springer
    Chromatographia 17 (1983), S. 88-92 
    Details
    ISSN: 1612-1112
    Keywords: Thermal desorption ; Internal calibration ; Atmospheric pollutants
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary The sampling of atmospheric polar organic compounds (amines, aldehydes, acids) generally requires the use of solid supports such as porous polymers. In most cases, resort to thermal desorption proves necessary. After reviewing the various possible adsorbents and the thermal desorption procedures decribed in the literature, this paper points out the possibilities and limitations of the technique, taking as a simple example toluene on activated acharcoal. A practical and reliable “Internal calibration” method is proposed.
