    Notes: Abstract Mediator release was examined from superficially lying cells in the airway epithelium obtained by bronchoalveolar lavage (BAL) in 13 non-atopic individuals. The BAL-cells were incubated (20 min, 37°C) withStaphylococcus (Staph.) aureus or with human influenza A virus.Staph. aureus was found to release histamine from cells from 7 of the 13 individuals and influenza A virus in 3 of 5 persons. Furthermore,Staph. aureus stimulated the BAL-cells to release leukotriene B4 in 7 of 11 subjects, whereas no release was found by influenza A virus in 7 examined persons. When cells from 4 persons were stimulated withStaph. aureus no release of leukotriene C4 was found. The mediator release caused by bacteria and virus might be of importance for the exacerbation of bronchial asthma in upper respiratory tract infections, since histamine is assumed to increase the epithelial permeability with entrance of allergens and other insulting particles, and leukotriene B4 facilitates airway inflammation.

    Notes: Histamine release induced by Staphylococcus aureus was examined in cells obtained by bronchoalveolar lavage (BAL) in non-topic individuals. Approximately half of the individuals responded with mediatior release to the bacterium, and the release was found to be time- and concentration dependent. No difference was found between the patients obtained by who responded and those who did not respond in regard to age, sex, smoker/nonsmoker % recovery of BAL-fluid, total cell count, differential cell counts, histamine content per mast cell, or diagnoses. Also stimulation of the BAL-cells with the calcium-ionophore A23187 resulted in histamine release, S. aureus-induced histamine release from basophils was examined in leukocyte suspensions obtained from the same individuals, and in all experiments release was found. The dose-response curves were similar to those obtained with BAL cells- The bacteria-induced mediator release from superficially lying cells in the airways epithelium might be of importance for the precipitation or exacerbation of bronchial asthma in respiratory tract infections.

    Description / Table of Contents: Résumé Une nouvelle méthode d'insertion de tube oesophagien est proposée. Chez les malades qui présentent des tumeurs oesophagiennes sténosantes inopérables, l'introduction du tube au travers du cancer a pour but de supprimer la dysphagie et la salivation. La technique consiste d'abord à dilater le défilé tumoral par l'appareil de Eder-Puestow puis à introduire correctement le tube sous contrôle endoscopique. 28 malades ont bénéficié de l'introduction d'un tube dit de Célestin. La méthode n'est grevée que de rares complications. Elle représente une alternative aux méthodes chirurgicales d'introduction d'un tube endo-oesophagien.
    Notes: Abstract A new method for inserting endoesophageal tubes is described. In patients with stenosing, inoperable esophageal malignancies, a passage through the neoplastic masses must be secured to avoid dysphagia and salivation. By first dilating the tumor lumen with the Eder-Puestow apparatus and then inserting the correctly cut tube using endoscopic equipment, an operation can be avoided. In 28 patients, a Celestin tube was thus inserted. The method involved only a few complications. It can be recommended as an alternative to existing operative methods for endoesophageal intubation.
