Concentration of thyroid hormone in skeletal muscle
Abstract:
1. A modified method for the determination of thyroid hormone levels in muscle is described. 2. The levels of T4 and T3 in skeletal muscle tissue of rats lie in the same range. 3. The level of T4 in plasma is about a hundred times higher than that of T3. 4. To remove plasma hormones from the tissue in which hormone levels are to be determined, the animals should be perfused with saline before tissue samples are taken.
