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.
