Abstract

An examination of the binding of antagonists to the receptors in rat cerebral cortex has shown that this occurs to an apparently uniform set of sites (8). Furthermore, the binding constants so obtained are in close agreement with those estimated by antagonism of the contraction of the longitudinal smooth muscle of guinea pig ileum. However, it has been reported by Barlow et al. (1) that the activity of some antagonists on guinea pig heart was not identical to that on the ileum.
