Isocyanates are highly reactive chemicals capable of causing a multitude of toxicologic effects including respiratory irritation, dermal irritation, contact sensitivity, and pulmonary hypersensitivity. In order to probe the mechanism(s) underlying these reactions, an animal model has been developed. The guinea
