Abstract

The process of repairing the myocardium ischemized areas was studied in young rabbits. On the 14th day after operation lipofuscin granules were found to accumulate in large quantities in the myocardial infarction area. Their luminescent spectral characteristics were identical to those of lipofuscin granules of old people. Accumulation of lipofuscin in ischemized areas of the young animal heart indicates an active metabolic role played by lipofuscin in post-infarction normalization of myocardium tissue functioning.

摘要

在幼兔身上研究了心肌缺血区域的修复过程。术后第14天,发现脂褐素颗粒大量积聚在心肌梗死区域。它们的发光光谱特征与老年人的脂褐素颗粒相同。幼龄动物心脏缺血区域脂褐素的积累表明脂褐素在心肌组织梗死后功能恢复正常化过程中发挥了积极的代谢作用。
