title: Benzpyrene exposure at 15 days of prenatal life reduces the binding capacity of thymic glucocorticoid receptors in adulthood.
abstract: 1. The offspring of female rats treated with a single dose of benzpyrene on day 15 of gestation showed in adulthood a significant relative decrease in the number of thymic glucocorticoid receptors, without an appreciable decrease in binding affinity. 2. There is experimental evidence that exposure to a hormone analogue in the early stage of organogenesis effects receptor development and the maternal organism fails to confer protection against that untoward influence.
