Diurnal rhythm in the adrenal ascorbic acid concentration of the rat

Effect of Oxygen on Growth of Cultured Myocardial Cells

“…In fact, dehydroascorbic acid does appear to be associated with mitoticaHy dormant, but well differentiated, actively functioning cells. For example, in adrenal cortex, when dehydroascorbic acid concentrations are lowest, the mitotic rates are highest and hormonal function is at its lowest level (11).…”
