Dose response relationships and interference of simultaneous skin tests in delayed hypersensitivity.
The relationship between the intensity of the delayed hypersensitivity reaction and the dose of antigen used for its elicitation change with time after sensitization. At three weeks the reactions to 100 mug of egg albumen were little different from those to 1 mug but at 14 weeks 100 mug gave much stronger reactions. This means that to follow the development of a delayed hypersensitivity respons...
A variety of in vivo and more recently in vitro assays have been described to assess cell mediated immunity (CMI). Two methods routinely employed in our laboratory to assess CMI following exposure to chemicals in rodents include delayed hypersensitivity and in vitro lymphoproliferation. Preliminary studies indicate that depressed delayed hypersensitivity responses, as performed by a radiometric...
