Abstract

Serum concentrations of T4 and T3 in 2 year-old Rats were decreased by about 30% compared to 2 month-old animals, but rT3 was similar. Activities of old Rats' liver mitochondria were near those of young thyroidectomized animals. Low circulating T3 partly explains metabolic changes observed during senescence.

与2月龄大鼠相比，2岁大鼠血清T4和T3浓度下降约30%，但rT3相似。老龄大鼠肝脏线粒体活性与去甲状腺幼龄大鼠相近。低循环T3部分解释了衰老过程中观察到的代谢变化。
