Abstract:
The effect of the opiate receptor antagonist naloxone on myocardial contractility and relaxation after acute coronary occlusion in rabbits and the relationship between its effect and ?-adrenergie receptor were observed. The results showed that during the early stage of acute coronary occlusion myocardial contractility and relaxation were significantly increased and cardiac function was improved by naloxone; The action of naloxone can be abolised by ?-adrenergic receptor blocker propranolol. These results indicated that there was a close correlation between the action of naloxone on myocardial contractility and relaxation and the adrenergic nerve activity.
