In this study, we examined the salivary titers of immunoglobulin A2 (IgA2) directed against pathogenic hemagglutinin (HA) antigens derived from influenza virus strains (hereinafter, shortened to IgA2) after XEN administration by inhalation via a nasal cannula for 15 min in healthy volunteers. The salivary titers of IgA2 directed against HA antigens were measured using an originally constructed enzyme immunoassay system. The results indicated significant increases of the salivary IgA2 directed against the HA antigens derived from the following influenza virus strains after 15 min of XEN inhalation, as compared to the titers recorded prior to the inhalation: A/ California/7/2009/H1N1 (P = 0.028), A/Hong Kong/4801/2014/H3N2 (P = 0.047), vaccine-type containing HA antigens derived from influenza virus strains, A/Singapore/GP1908/2015/H1N1, A/Hong Kong/4801/2014/H3N2, B/Texas/2/2013/Victoria system, and B/Phuket/1307/2013 /Yamagata system (P = 0.039). Taken together, XEN rapidly enhanced the salivary titers of IgA2 directed against HA antigens derived from influenza viruses, which may imply a role in the protection against influenza virus infection by activation of humoral immunity (IgA2 action) in the whole body via the nasal mucosal immune system.}, pages = {69--74}, title = {水素ガスを含む蒸気混合ガス吸入後のインフルエンザウイルス由来のhemagglutinin抗原に対する唾液中IgA抗体価の増強}, year = {2019}, yomi = {イケワキ, ノブナオ and ソノダ, トオル and アズマ, カズヒロ} }
