Effect of Epinephrine upon Plasma Optical Density,Unesterified Fatty Acids,Lipemia Clearing and Heparin Levels

Abstract

Summary

Immediate effects of intravenous epinephrine in dogs and humans upon plasma optical density, lipemia clearing activity, unesterified fatty acids and heparin levels were determined. There was no change in the first 2 parameters. Unesterified fatty acids were definitely increased in both species. Circulating heparin was increased in 3 of 4 humans studied. These findings indicate that elevation of unesterified fatty acids did not occur as a result of enhanced plasma triglyceride lipolysis, and that the rise in heparin was probably part of a stress reaction unrelated, in this instance, to its role in fat transport.
