Abstract
Two somatostatin analogs (SA) and 17-.alpha.-dihydroequilin (E) inhibited the stereospecific binding of 3H-naloxone in vitro to rat brain opiate receptors in the absence of Na. The addition of Na indicated the SA to be greater or similar in potency to somatostatin as opiate agonists and E to be an opiate antagonist. SA and certain steroids may affect endorphin containing neurons.
