title: Modulatory effects of vasopressin on glucose and protein metabolism during food-restriction stress.
abstract: Plasma levels of glucose and urea nitrogen were compared in vasopressin-containing (LE) and vasopressin-deficient (DI) rats under ad lib and food-restricted conditions. In the ad lib situation, DI and LE rats had similar levels of glucose and urea nitrogen. Variations in this pattern were observed under food-restricted conditions. The DI animals exhibited lower levels of glucose and higher levels of urea nitrogen than their LE counterparts. During food restriction, the glucose levels of LE animals were not different from that observed under ad lib conditions. A significant decrease, however, was observed in the glucose levels in DI animals during food restriction. Urea nitrogen levels in LE animals decreased during food restriction as compared to the ad lib situation, whereas urea nitrogen levels of DI animals increased during food restriction. These observations indicate that vasopressin has a modulatory role on glucose and protein metabolism during the stress of food restriction.
