Histamine-induced relaxation of the sheep bronchus was antagonized by burimamide but not by mepyramine, indicating the presence of H(2)-receptors. Mepyramine or burimamide alone produced partial antagonism of histamine-induced relaxation of the cat trachea. Both inhibitors added simultaneously effectively abolished the histamine response, suggesting that both H(1)- and H(2)-receptors are active in relaxing the cat trachea.
组胺诱导的绵羊支气管舒张作用被布立马胺拮抗,但不被美吡拉敏拮抗,这表明存在H(2)受体。单独使用美吡拉敏或布立马胺可部分拮抗组胺诱导的猫气管舒张。同时加入这两种抑制剂可有效消除组胺反应,提示H(1)和H(2)受体在猫气管舒张中均起作用。
