title: Effects on erythroid colony formation of beta(beta)-agonists, etiocholanolone and spleen extract from irradiated rats.
abstract: Erythroid colony formation in vitro was enhanced by beta-agonist, etiocholanolone and spleen extract from irradiated rats. While propranolol completely blocked the effect of beta-agonists, the effect of etiocholanolone was little, and that of spleen extract was not affected by this beta-blocker.
