[Changes in the concentration of glucose, fructose, insulin and free fatty acids in the blood plasma as well as of lactate and pyruvate in the blood of cattle after i.v. adrenaline, insulin and noradrenaline infusion].
The glucose, free fatty acid, and insulin levels in the blood plasma of young cattle underwent temporary but considerable rises, following intravenous infusion of adrenalin, doses being 2.5 or 5.0 micrograms/kg body weight. The average weight of these animals was 106.3 kg. The same findings were obtained from adult cattle, weighing 419.3 kg on average. A temporary but unambiguous rise of lactate in the blood was additionally recorded from young cattle. Adult cattle exhibited a temporary rise of fructose in the blood plasma. Regulation causing reflux of the analysed blood components and their return to their original levels or even below those was faster in cattle than it had been in sheep. Administration of insulin to cattle caused, within 45 minutes, decline of glucose in blood plasma from 8 mg/100 ml to 10 mg/100 ml. Intravenous application of adrenalin (5.0 micrograms/kg) increased the glucose level to 45 mg/100 ml or even 57 mg/100 ml, within five minutes. The lipolytic action of adrenalin was low under those conditions. Noradrenalin (5.0 microgram/kg body weight) exhibited merely medium glycogenolytic action but no lipolytic action at all.
