title: Specific immunological therapy with the sulfite chemicals.
abstract: Provocative oral tests with 1000 mg of the sulfite chemicals produced allergic reactions in 10% of the patients tested. Parenteral therapy with an Allpyral extract of the sulfite chemicals was instituted. After 3 months' therapy three patients were challenged with 1000 mg of the sulfite chemicals and modified attacks of asthma were produced. After 6 months' therapy the same three patients failed to react. Therefore, I rechecked all patients after 6 or more months of therapy. Thirty-five patients were retested; 29 failed to react and six reacted with allergic symptoms. The 29 patients no longer reacted to foods treated with the sulfite chemicals.
