Effects of surgical thyroidectomy and l-thyroxine on the oxidative metabolism and hemopoiesis of spotted munia, Lonchura punctulata

Abstract Thyroidectomy in spotted munia produced a significant decrease in the oxygen uptake by liver, number of red blood corpuscles, packed cell volume and hemoglobin concentration. Thyroxine when administered in vitro and in vivo elevated the oxygen consumption by liver cells of thyroidectomised birds but had no effect on the oxygen uptake by muscle or on the blood picture.
