The stress of injected epinephrine was reckoned from the reduction of ascorbic acid in the adrenal. In a young rat given epinephrine on day 3 after birth by spontaneous delivery, a depletion of ascorbic acid was not observed. Among similar young rats which were pretreated with hormones (LH, estradiol benzoate, testosterone propionate, progesterone, blood serum of pregnant rat and acetone-extract of rat placentae) and then given epinephrine, those of the group treated with LH and those of the group treated with extract of placentae showed significant depletions of the ascorbic acid in the adrenals. In newborns from spontaneous deliveries and in premature newborns obtained by Caesarean section, the weights of the adrenals declined during the first 24 hrs. ex utero-declined in fasted young and in nursed young.
