Abstract
Autoradiography was used to study the distribution of 2,2'-14C-methylene-bis-(3,4,6-trichlorophenol) (HCP) in pregnant marmoset monkeys in early (day 30-50) and late (around day 120) gestation and in a newborn (11 days old) pup. Radioactivity was present in the conceptus at all stages of gestation, although the foetal concentration was lower than the maternal. In the embryo an accumulation was observed in the neural tube and in the embryonic membranes. In the late foetus and newborn monkey the highest concentration of radioactivity was found in the liver and the intestinal contents. The brain of the adult and newborn animals showed low concentration. A partial blood-brain barrier was present in the late foetus but, in relation to other tissues, the foetal brain concentration was higher than that of the mother.
