The emetic action of noradrenaline was investigated in unanesthetized cats, after it was injected into the cerebral ventricles through chronically implanted cannulae. Intracerebroventricular injection of noradrenaline produced dose-dependent and shortlasting emesis, which was abolished after ablation of the area postrema.

In isolated rat hearts effects of chloropyramine (CP), histamine H1 antagonist, and famotidine (FA), H2 antagonist, upon two different myocardial injuries, ischaemia-reperfusion and hypoxia-reoxygenation were studied. In both types of injury the effects of drugs were seen mainly during reperfusion

Using human platelet-rich plasma (PRP) we found that histamine concentration-dependently potentiated platelet aggregation induced by platelet-activating factor (PAF). When added separately, neither histamine nor chloropyramine, a competitive antagonist of H1 receptors, influenced platelet aggregation, however BN 52021, a specific PAF
