Notes:
Results of the optimization method and of other methods used to assess contact allergy in laboratory animals were compared with known epidemiological data on the occurrence of hypersensitivity reactions in man. Tests were performed with preservatives {formalin, ethylenediamine and sorbic acid), drugs (penicillin G, benzocaine and sulphathiazole) and other contactants belonging to widely different chemical classes (p-phenylenediamine, triclosan, pyrazole derivatives, nickel and chrome salts, eugenol, isoeugenol and mercaptobenzothiazole). The degree of sensitization achieved in guinea pigs by the optimized procedure (intradermal test with adjuvant combination) and the maximization procedure was invariably superior to that produced by the epidermal method using prior irritation of the site of application. Both the optimized procedure and the maximization test seem to be capable of identifying contact allergens that cause hypersensitivity reactions in as few as t in 10,000 of the human population as a whole. The optimization test merits consideration as a standardized and efficiently predictive procedure.
