细胞间连接以及非连接性的离子通道是海绵体平滑肌张力调节的重要物质基础。后者中各种K+ 通道在细胞产生静息电位以及细胞活化后的跨膜电位中起重要作用。本文综述了各种K+ 通道在阴茎勃起生理过程中所起调节作用的机理 ,并探索作为海绵体平滑肌张力调节重要因素之一的K+ 通道在治疗阴茎勃起功能障碍中的应用前景 Cell junctions and non-connective ion channels are important material bases for the regulation of sponge smooth muscle tone. The latter K + channels play an important role in the generation of resting potentials in cells and in the transmembrane potential after cell activation. This review summarizes the mechanisms by which K + channels regulate penile erection and explores the potential applications of K + channels in the treatment of penile erectile dysfunction as one of the most important factors in the regulation of spontaneous smooth muscle tone
