摘要：

The effects of barium ions on slow acetylcholine (Ach) H receptor activated hyperpolarization has been studied. The results provide evidence of a sensitive and reversible blocking action of Ba2+ on the involved potassium conductance. 3-Aminopyridine (3-AP) also attenuated the slow H-response by 50%, showing partial effectiveness. TEA+ sensitively inhibited the Ach evoked hyperpolarization interacting with the receptors. © 1979.
