[Oxidative phosphorylation in the intact and regenerating liver from a chronobiological viewpoint].
The dynamics of oxidative phosphorylation of the regenerating liver mitochondria on the endogenous and exogenous (glutamate, succinate, ascorbate) substrates in comparison with the normal diurnal and seasonal changes of this process was studied by the polarographical method. With the increase of its activity reflecting the deviation from the state of physiological rest (intact liver in spring, autumn, winter; regenerating liver), the range and synphasing of the oxidative phosphorylation indices were decreased, their bimodal distributions were transformed into the monomodal ones down to the full loss of diurnal periodicity. The degree of the process desynchronization depends, thus, directly on the degree of its activity.
