| Outline of Final Research Achievements |
We investigated whether the use of 10 kinds of antiseptic agents―employed in clinical practice, commercial facilities, and homes―aggravates mite-induced atopic dermatitis-like skin lesions in NC/Nga mice. We noted that the topical application of benzalkonium chloride, benzethonium chloride, and triclosan on lesion sites in mice markedly exacerbated mite-induced atopic dermatitis. Moreover, the topical application of povidone-iodine and ethanol also aggravated the lesions. In contrast, the topical application of chlorhexidine gluconate, alkyldiaminoethylglycine hydrochloride, acrinol, chloroxylenol, and isopropyl methylphenol did not aggravate atopic dermatitis-like skin lesions. The aggravation induced by antiseptic agents was associated with the infiltration and proliferation of inflammatory cells, as well as with the increased levels of cytokines and chemokines in subcutaneous inflammation sites.
