水晶体カプセルとセルロース膜との複合膜の膜電位と膜透過係数

抄録

Eye-lens capsule has one layer of epithelium inside its anterior part and this epithelium was found to be a negatively charged layer from measurement of the membrane potential of epithelium-capsule.²⁾ Theoretical equations were derived for the membrane potential and the membrane permeability coefficient of the membrane, composed of a positively charged membrane and a negatively charged membrane. The membrane composed of a capsule, which was positively charged, and a cellulose membrane, which was negatively charged, were considered as a model membrane of epithelium-capsule and the theoretical equations were applied to this composed membrane. These theoretical values were in good agreement with the observed values when the parameter values of the membrane charge density θ^* and the transport number of anion t^*_- measured for each component membrane were used.
