The influence of artificially generated atmospheric ions is studied in 15 patients with bronchial asthma. A slight but significant (at 5% level) improvement in the lung function was demonstrated in nine patients during positive as well as negative ion exposure, but the patients' subjective votings of the air quality did not show any changes due to ion exposure. No change in the histamine threshold of the airways in six patients with bronchial asthma was demonstrated during exposure to ions. Further controlled studies with electro-aerosols are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
