In different mammalian species, there is surprisingly great variation of the delayed hypersensitivity response to tuberculin: man, guinea pigs and rabbits exhibit strong responses , while rats, mice and cats display 'much weaker reactions .
This inhibition of migration seems characteristic of cells from animals with delayed hypersensitivity since exudates cells obtained from non-hypersensitive animals immunized to produce only circulating antibody are not inhibited by antigen.
Reduce immune delayed hypersensitivity (allergy) reactions that
population, by comparison, delayed hypersensitivity reactions are not
Because a delayed hypersensitivity
reaction to a previously sensitized antigen occurs, patients who had not been previously vaccinated with bacille Calmette-Guerin (BCG) were not eligible for this study.
Quantitative hepatitis B surface antibody titers were compared with reference to subjects' sex and delayed hypersensitivity
responses using a two-tailed t test.
In lower concentrations, eugenol can act as a contact allergen evoking a localized delayed hypersensitivity
The bad news: Type IV delayed hypersensitivity
to other chemicals found in gloves-or that readily permeate gloves-is on the rise, Dr.
019), delayed hypersensitivity
was noted in three patients: one with angiodema after cycle 8, and one each with uticaria and serum sickness after cycle 4.
A photosensitivity reaction, occurring mainly on sun-exposed areas, is a delayed hypersensitivity
reaction reflecting direct cellular damage produced by the photochemical reaction between a chemical photosensitizer and the appropriate radiation on the skin and is independent of dose and duration of exposure (4).
2), (3) For those with food allergies that are not IgE-mediated and associated with delayed hypersensitivity
reactions, estimates are more difficult to determine.
