Abstract
Isoproterenol enhanced myocardial triglyceride utilization and incorporation of exogenous fatty acid into triglyceride fraction in the perfused rat heart in the presence of glucose. However, in the absence of glucose, cardiac performance was considerably aggravated by isoproterenol. This suggests that glucose might be an essential fuel in the heart stimulated by isoproterenol.
摘要
在有葡萄糖存在的情况下，异丙肾上腺素可增强灌注大鼠心脏中甘油三酯的利用以及外源性脂肪酸掺入甘油三酯组分的过程。然而，在没有葡萄糖的情况下，异丙肾上腺素会使心脏功能显著恶化。这表明葡萄糖可能是异丙肾上腺素刺激下心脏的必需燃料。
