摘要：

Sodium enriched pregnant rat myometrial cell hyperpolarized within two minutes of exposure to potassium containing medium without detectable change in tissue potassium content. The hyperpolarization, which exceeded the potassium equilibrium potential, was temperature- and potassium-dependent and abolished by ouabain. These findings suggest that an electrogenic sodium pump is responsible for the observed hyperpolarization. © 1969.
