title: The effects of CBG on the in vitro reduction of 3H-progesterone by liver homogenates and cell suspensions.
abstract: The effects of CBG on 3H-progesterone metabolism by ovine, bovine and rat liver homogenates and bovine and rat liver cell suspensions were studied. As a source of CBG served plasma from "estrogenized" women. Same plasma, pretreated at 60 degree for 20 min. served as control. It was found that the amounts of 3H-progesterone remaining after incubation were higher in the presence of CBG, as compared with control incubations, when using the homogenates. No such effect was observed in case of cell suspensions.
