Abstract:-Prolongation of prothrombin time (PT) induced by industrial chemicals was characterized using a database of repeated dose toxicity studies, HESS DB. Of the 685 chemicals in the DB, 20 chemicals markedly prolonged the PT by more than 150% of that of vehicle control. Prolonged PTs were detected in males for 20 chemicals but no significant prolongation of PT was observed in females for 19/20 chemicals, indicating that males are apparently more susceptible to PT prolongation than females. The effective dose of th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
