Some of the effects of dipyridamole, hexobendine and lidoflazine on mechanical responses in rabbit duodenum have been investigated. In concentrations known to inhibit tissue accumulation of adenosine and its metabolites, none of these agents potentiated inhibitory responses to intramural nerve stimulation or to application of adenosine, adenosine triphosphate or phenylephrine. These results neither support nor dispute the suggestion that adenosine or a related nucleotide is the intramural inhibitory transmitter but do show that tissue accumulation in rabbit duodenum is not an important feature in the termination of the action of adenosine.
已对双嘧达莫、己酮可可碱和利多氟嗪对兔十二指肠机械反应的某些作用进行了研究。在已知能抑制腺苷及其代谢产物在组织中蓄积的浓度下,这些药物均未增强对壁内神经刺激或对应用腺苷、三磷酸腺苷或去氧肾上腺素的抑制反应。这些结果既不支持也不反驳腺苷或相关核苷酸是壁内抑制性递质这一观点,但确实表明兔十二指肠中的组织蓄积并非腺苷作用终止的重要特征。
