Contact hypersensitivity response to isophorone diisocyanate in mice.

Abstract

Isophorone diisocyanate was evaluated for its potential as a sensitizing agent for allergic contact hypersensitivity in mice. Female B6C3F1 mice were sensitized with 0.1, 0.3, and 1.0% isophorone diisocyanate and challenged with 3.0% isophorone diisocyanate. Doses of isophorone diisocyanate were selected from assays for primary irritancy. Mice received 20 microliters by direct dermal application, for 5 days, to sites prepared by shaving, dermabrading and, in some mice, with intra dermal injection of complete Freund's adjuvant. The rest period was 7 days. Measurement of the contact hypersensitivity response in mice was by radioisotopic assay two days after challenge and mouse ear swelling one and two days after challenge. Mice demonstrated statistically significant dose-dependent contact hypersensitivity responses to isophorone diisocyanate with or without adjuvant pretreatment.
