Abstract

Adipose tissue from rats fed high fat diets were found to exhibit significantly less adrenaline-induced FFA release than those from rats maintained on low fat commercial diet.

Addition of CPIB to the high fat diet reversed this suppression of adrenaline-induced FFA release by isolated adipose tissue. Supplementation of the diet with cholesterol-cholate also reversed the suppressive effect of high dietary fat on adrenaline-induced lipolysis in vitro.

Adrenaline-induced FFA release in adipose tissue seems to depend upon the metabolic status of the tissue as determined by previous nutrition of the animal.

氯贝特和高脂饲料对肾上腺素诱导的离体大鼠脂肪组织脂解的影响
研究发现,喂食高脂肪饮食的大鼠的脂肪组织释放的肾上腺素诱导的FFA明显少于喂食低脂肪商业饮食的大鼠。在高脂饮食中加入CPIB,可以逆转肾上腺素诱导的游离脂肪酸释放的抑制作用。在体外实验中,在饮食中补充胆固醇-胆固醇也逆转了高脂肪饮食对肾上腺素诱导的脂肪分解的抑制作用。肾上腺素诱导的游离脂肪酸在脂肪组织中的释放似乎取决于组织的代谢状态,这是由动物以前的营养状况决定的。
