Biologic membranes display rectification of electrical current, as well as other properties, in many respects similar to precipitation membranes. The experiments reported here, performed in frog skin, show that these characteristics are dependent upon the presence of calcium. Upon elimination of calcium from the bathing solution, the property of electrical rectification is lost, the current-voltage relation assuming a linear form. Readministration of calcium brings about complete recovery of the rectification pattern. This behavior is analogous to chemical deconditioning of precipitation membranes. Our findings support the assumption that the binding of calcium in biologic membranes produces electrical effects characteristic of precipitation membranes.
生物膜在许多方面表现出电流整流以及其他特性，类似于沉淀膜。本文报道的在蛙皮上进行的实验表明，这些特性取决于钙的存在。当从浴液中去除钙时，电流整流特性丧失，电流 - 电压关系呈线性形式。重新添加钙会使整流模式完全恢复。这种行为类似于沉淀膜的化学去调节。我们的发现支持这样的假设，即生物膜中钙的结合产生了沉淀膜特有的电效应。
