Abstract
An assay has been developed and measurements of aryl hydrocarbon [benzo(a)pyrene] hydroxylase have been made in peripheral blood monocytes from a human population. Treatment with benz(a)anthracene in cell culture increased aryl hydrocarbon hydroxylase activity from 6.5-to 37-fold in monocytes from each of 25 apparently healthy donors. A weak correlation (r = 0.38) was observed between the induction ratios obtained with monocytes and lymphocytes from the same donors. Reproducibilities of the monocyte and lymphocyte assays were comparable. In monocytes, the measurement of basal and induced aryl hydrocarbon hydroxylase activity does not require pretreatment with mitogens as is the case with lymphocytes. Monocytes also exhibit a much wider range of induction ratios than do lymphocytes.
