Abstract
Summary
Hypophysectomized rats were treated with 0.01, 0.05 or 0.10 mg of thyroxin daily. Oxygen consumption in the 3 groups of animals was 100, 124 and 107% of normal; total erythrocyte volumes/100 g body weight were 83, 121 and 107% of normal. Hypophysectomized controls exhibited oxygen consumption 67% of normal with total erythrocyte volume/100 g body weight, 79% of normal. These data support the oxygen need theory of post-hypophysectomy anemia.
