摘要

胆红素在大鼠肝脏线粒体内积聚并诱导松散偶联。这种状态的特征是原动力正常,但耗氧量和内膜电导增加,可能损害细胞的能量代谢。在黄疸动物组织中,当胆红素浓度达到12-24 μm时,观察到松散耦合。

Bilirubin increases mitochondrial inner membrane conductance

Bilirubin accumulates within, and induces loose coupling in, rat liver mitochondria. This state, characterized by a normal protonmotive force, but increased oxygen consumption and inner membrane conductance, could impair cellular energy metabolism. Loose coupling is observed at bilirubin concentrations (12–24 μm) attained in tissues of kernicteric animals.
