Altogether 300 patients suffering from bronchial asthma were examined for serotonin metabolism, the kallikrein-kinin system and histamine. A study was also made of the information relations of the indicated parameters to diverse groups of the signs using Shannon's technique. It has been revealed that serotonin and the kallikrein-kinin system are of importance in the pathogenesis of changes in the efficacy of the diffusion lung capacity in severe bronchial asthma. The authors discuss the significance of excessive accumulation of serotonin and bradykinin as a marker of the impairment of endothelial function of pulmonary vessels, specified by the damaging action of free radicals and immune complex allergic vasculitis as well. Histamine along with macrophages act as delimiters of allergic inflammation, with their action being mediated by negative feedback.

The anti-allergic and anti-asthmatic activities of three potassium (K+) channel openers, cromakalim, pinacidil, and nicorandil, were investigated. 1) Forty-eight-hour homologous passive cutaneous anaphylaxis (PCA) in mice was not affected by cromakalim, pinacidil, or nicorandil. Ketotifen significantly inhibited the reaction. 2) Antigen-induced histamine release from sensitized guinea pig lung tissue was not affected by cromakalim, pinacidil or nicorandil (except for 10(-4) M nicorandil). Salbutamol inhibited the release of histamine. 3) Histamine, serotonin and LTC4-induced vasculitis in rat back skin was not affected by any of these three K+ channel openers. 4) Antigen-induced constriction of isolated sensitized guinea pig tracheal muscle was relaxed by each of the K+ channel openers. 5) Constrictions of isolated guinea pig tracheal muscle caused by high potassium, histamine, LTC4, or U-46619 were clearly relaxed by each of the three K+ channel openers. 6) Increases of airway resistance caused by histamine, LTD4, or U-46619 in guinea pigs in vivo were inhibited by administration of each of the three K+ channel openers. 7) Experimental asthma caused by the IgE antibody and antigen system in guinea pigs was inhibited by each of the three K+ channel openers.

The case is described of a 39-year-old man with acute generalized pustular bacterid and high Clq-binding activity in the sera during the active stage. Histamine-induced vascular changes studied by immunofluorescence microscopy revealed a perivascular deposition of IgM and C3. These findings support the view that leukocytoclastic vasculitis underlying the subcorneal pustules is mediated by immune complex deposition.
