Effects on Erythroid Colony Formation of Beta (β)-Agonists, Etiocholanolone and Spleen Extract from Irradiated Rats

Abstract

Erythroid colony formation in vitro was enhanced by β-agonist, etiocholanolone and spleen extract from irradiated rats. While propranolol completely blocked the effect of β-agonists, the effect of etiocholanolone was little, and that of spleen extract was not affected by this β-blocker.
