[Studies on lipid mobilization in obesity without glucose intolerance. 1st communication. Noradrenaline-stimulated lipolysis].

1. In obese patients with normal glucose tolerance the norepinephrine-induced lipolysis in vivo was significantly higher as compared with a non-obese group. This was observed both during weight-related and constant norepinephrine infusion. 2. In the obese group a discordant release of free fatty acids and glycerol and a significantly lower quotient of FFA/Glycerol than in the controls was found. It is supposed that in obesity the re-esterification of FFA is increased.
