Oscillations of membrane ionic conductivity, with a period similar to cell cycle duration, were observed in fertilized and activated loach (Misgurnus fossilis) eggs. In cleaving eggs the decrease in conductivity coincided with mitosis. Synchronously with the oscillations of membrane conductivity in activated as well as in fertilized eggs, rhythmic changes in blastodisc shape occurred. The blastodisc rounded up during the period of increasing membrane conductivity and flattened while conductivity decreased. Scanning microscopy of fertilized and activated eggs revealed differences in the surface relief of rounded and flattened blastodiscs.
在受精和激活的泥鳅（Misgurnus fossilis）卵中观察到膜离子电导率的振荡，其周期与细胞周期持续时间相似。在分裂的卵中，电导率的降低与有丝分裂同时发生。与激活卵和受精卵中膜电导率的振荡同步，胚盘形状发生有节奏的变化。在膜电导率增加期间，胚盘变圆，而在电导率降低时变平。对受精卵和激活卵的扫描显微镜观察揭示了圆形和扁平胚盘表面起伏的差异。
