Abstract

IT is generally accepted that histamine plays an important part in anaphylactic shock. In recent years, attention has been directed to 5-hydroxytryptamine, since this substance, together with histamine, is liberated from the platelets by the antigen–antibody reaction1. Further, 5-hydroxytryptamine causes a shock syndrome in guinea pigs which is similar to that caused by anaphylaxis2. Although Herxheimer was unable to protect guinea pigs from anaphylactic shock using lysergic acid diethylamide, a potent and specific antagonist of 5-hydroxytryptamine, Pallotta and Ward3 have observed significant protection using intravenous doses of lysergic acid diethylamide.
