A theoretical explanation is given of the screening-binding effects of various magnesium salts on the ionic permeability of epithelial amniotic cell membranes. It is suggested that the 'screening process' induces an increase in the electrical membrane resistance and in membrane stability which is a unique action at low concentration. At high concentration, the binding process induces a reduction or an increase in these parameters as a function of the magnesium salt present. The different effects are due to changes in the distribution and in the repartition of the fixed charges on the cell membrane.
本文给出了各种镁盐对羊膜上皮细胞膜离子通透性的屏蔽结合效应的理论解释。研究表明，“屏蔽过程”会导致膜电阻和膜稳定性增加，这是低浓度下的一种独特作用。在高浓度时，结合过程会根据所存在的镁盐使这些参数降低或增加。不同的效应是由于细胞膜上固定电荷的分布和重新分布发生了变化。
