[The influence of hexoprenalinsulfate aerosol on the ciliary wave frequency of the respiratory epithelium (author's transl)].

A report is given on the possible influence of hexoprenalinsulfate on the mucociliary wave frequency of the mucous membrane of the respiratory tract. The object of investigation was native human tracheaL mucosa obtained by tracheotomies. It was shown, that there was a significant decrease in frequency just on account of the usual gas fraction of the aerosol spray. If air was used instead of the gas, hexoprenaline did not influence the ciliary wave frequency.
