Abstract

Hepatic portal and arterial blood flow and the net hepatic uptake of individual free fatty acids (FFA) were measured in sheep during intravenous infusions of saline and noradrenaline (2 mu kg-minus 1 min-minus 1). During noradrenaline infusion in FFA increased in the circulating (arterial) plasma in amounts oleate greater than palmitate greater than stearate. Changes in the hepatic uptake of FFA opposed these changes in plasma FFA composition; the hepatic uptake of oleate increased more than that of palmitate, and the uptake of stearate fell slightly, but not significantly.

摘要

在绵羊静脉输注生理盐水和去甲肾上腺素(2微克/千克体重·分钟)期间,测量了肝门静脉和动脉血流量以及肝脏对各游离脂肪酸(FFA)的净摄取量。在输注去甲肾上腺素期间,循环(动脉)血浆中的FFA增加,油酸增加的量大于棕榈酸大于硬脂酸。肝脏对FFA摄取的变化与血浆FFA组成的这些变化相反;肝脏对油酸的摄取增加幅度大于棕榈酸,硬脂酸的摄取略有下降,但不显著。
