| Abstract: | The increase in serum cortisol concentrations following naloxone administration to female pigs was abolished by hypophysial stalk-transection, even though CRH and ACTH stimulated cortisol release in these animals. We suggest that the opioid antagonist enhances cortisol secretion primarily by a central action in pigs. |
