title: [Age and the relationship between temperature and the cell membrane repolarization process in the adrenal cortex].
abstract: In experiments on the isolated adrenal glands of rats aged 5 and 28--29 months no age-related differences in the membrane potential were found in the cells of zona fasciculata of the adrenal cortex. The temperature dependence of the membrane repolarization of the adrenal cortex zona fasciculata was was investigated within the range of 7--17 degrees C following preliminary cooling of the adrenal glands. The calculated value of the temperature coefficient of the repolarization process was much higher in old than in young rats. With ageing the reactions with high energy activation made a greater contribution to the total balance of processes determining membrane repolarization in the adrenal cortex cells.
