Abstract:
:Intrahepatic and intracerebral metabolic responses to neonatal fasting or enteric carbohydrate alimentation were investigated among newborn dogs. Pups were either fasted or given an intravenous glucose infusion (alimented) before an enteric feeding of physiologic quantities of either glucose or galactose. These pups were also compared to another group which was completely starved throughout the study period. Gastrointestinal carbohydrate feeding resulted in enhanced hepatic glycogen content among pups after a prior state of fasting. Though there were no differences of glycogen content between glucose or galactose feeding in this previously fasted group, combined intravenous glucose and enteric galactose administration produced the greatest effect on hepatic glycogen synthesis. Intrahepatic fructose 1, 6-diphosphate and phosphoenolpyruvate levels were increased among previously fasted pups fed enteric monosaccharides compared to completely starved control pups, whereas intrahepatic phosphoenolpyruvate and pyruvate levels were elevated after combined intravenous and enteric carbohydrate administration. Of greater interest was the observation that hepatic levels of ATP were significantly elevated among all groups given exogenous carbohydrates compared to the completely starved control group. In contrast to the augmented hepatic glycogen and ATP levels, there were no alterations of cerebral glycogen or ATP after alimentation. Nevertheless, cerebral pyruvate and/or phosphoenolpyruvate concentrations were elevated after enteric or combined intravenous and enteric alimentation compared to the totally starved control pups.
