  • Title: [Arterial plasma histamine concentration for airway obstruction due to different areas of the bronchial system. IV. Communication (author's transl)].
    Author: Zimmermann I, Ulmer WT.
    Journal: Res Exp Med (Berl); 1980; 177(3):193-200. PubMed ID: 7444176.
    Abstract:
    The separate inhalation of A.E. aerosol in the upper and the peripheral parts of the airways in allergic dogs is followed by an increase of the histamine concentration in the arterial plasma. The correlation between the plasma histamine concentration and dynamic elastance and the correlation between dynamic elastance and arterial oxygen pressure is very similar following the challenge of the upper and the peripheral parts of the airways. The results argue for reflex bronchoconstriction also by challenge of the more peripheral airways. The results are in accord with the idea that the answer of Edyn depends on a product of local histamine concentration and the area in which the histamine is released. The number of sensory receptors per surface area which is suspected to be greater in the upper part of the airways may also be important.
