[Behavior of various blood constituents (glucose, fructose, insulin, lactate, pyruvate, free fatty acids, inorganic phosphate) and the half-life of monosaccharides in plasma after i.v infusion of glucose, fructose, galactose and invert sugar solutions in ruminants. 3. Studies in sheep].
Monosaccharide half-life as well as the effects of intravenous infusion of 0.5 g/kg body weight glucose, fructose, and invert sugar solutions on insulin levels in blood plasma as well as on pyruvate and lactate concentrations in the blood were measured in two adult sheep weighing 72 kg and 65 kg. The half-life values for glucose were 16 minutes and 19 minutes and that for fructose 20 minutes. Glucose half-life, following infusion of invert sugar, was 35 minutes or 25 minutes, while that of fructose was 16 minutes in either case. Infusion of fructose solution was followed by a somewhat sizeable and prolonged rise of the glucose levels in blood plasma. Infusion of glucose solution resulted only in short-time increase of fructose concentrations in blood plasma. The highest insulin rise in blood plasma was found to have taken place in response to infusion of fructose solution. Pyruvate and lactate concentrations underwent merely minor changes. Reference is made to the potential benefit of using invertose solution in the treatment of ketosis (cf. second communication).
