title: Erythropoietin levels in heterozygous alpha-thalassemia.
abstract: In guinea pig bone marrow cultures with heterozygous alpha-thalassemic serum, 59Fe uptake values are elevated above iron values of cultures with serum of normal subjects. These results show that erythropoietin (EP) activity values in heterozygous alpha-thalassemia are comparable to those previously observed by ourselves in heterozygous beta-thalassemia despite of the different Hb concentration in these thalassemic syndromes. This points to the existence of signals which regulate Ep synthesis independently of Hb levels.
