Analogies in temporary causal correlations
between intensity of energetic metabolism and cell electrogenesis
processes, between ions homeostasis regulation, processes causing
changes of intracellular K+ concentration, K+/Na+
ratio and changes of embryo membrane polarization are detected. A difference
in temporary correlations between changes cytoplasmatic рН and changes of
bioelectric parameters on little-hour interval is detected also
for these objects. The analysis of periodicity in temporary
changes of all parameters is carried out. Conformity of mitotic
cycle duration at early stages of cleavage to the oscillation
periods of membrane voltage, endogenous calcium concentration,
speed of oxygen absorption and cytoplasmatic рН – for loach,
and to the membrane voltage and endogenous calcium concentration –
for xenopus.
