Abstract
It is shown that incubation of EAT cells in the presence of Fe2+ ions caused the threshold decrease of active and capacitance constituents of cell suspension impedance and rate of ion efflux from cells to the isotonic sucrose media, and decrease extent rose with an increase of Fe2+ ion concentration and temperature. A discrepancy between the results described and experimental model system data is discussed.
摘要
结果表明，在Fe2+离子存在的情况下孵育EAT细胞，会导致细胞悬液阻抗的活性和电容成分以及离子从细胞外流到等渗蔗糖培养基中的速率阈值降低，且降低程度随Fe2+离子浓度和温度的升高而增加。文中讨论了所描述的结果与实验模型系统数据之间的差异。
