Summary
Similar diurnal periodicity in oxygen consumption of liver slices in Wistar rats was observed as that previously found in Sprague-Dawley rats. The rate of oxygen consumption was low in the morning and high in the evening. After inversion of lighting regimes, the phase shifted and reached the reversal curve in about 30 days. On the basis of these findings, it is estimated that diurnal periodicity in oxygen consumption of liver slices is influenced by alteration of the periods of light and darkness. Liver glycogen rhythm showed a reversed correlation to that of oxygen consumption in both lighting regimes.
