title: Effects of ethanol, fructose, and ethanol plus fructose infusions on plasma glucose concentration and glucose turnover in monkeys (Macaca fascicularis) as measured by [6-3H]glucose.
abstract: Six adult, female, cynomolgus monkeys were fasted for 64 hr and then continuously infused with [6-3H]glucose to determine the rates of glucose turnover and clearance while they were also being infused with ethanol (110 mumol/min/kg), 1,3-butanediol (110 mumol/min/kg), fructose (30 mumol/min/kg) or ethanol plus fructose (110 and 30 mumol/min/kg) respectively. Both ethanol and 1,3-butanediol infusions decreased the glucose turnover rate (the steady-state input-output rate from the plasma glucose pool) and the plasma glucose concentration by halving the glucose production rate. In contrast, fructose infusions increased the glucose turnover rate and glucose concentration by increasing the glucose production rate by 20%. The plasma clearance rate of glucose was lowest when the animals were infused with ethanol plus fructose; this suggests that acetate from ethanol oxidation may have a glucose-sparing effect if normoglycemia is maintained.
