to demonstrate the autoimmune origin of some cases of aplastic anemia , we have studied the effect of antilymphocyte globulin ( alg ) on the hematopoiesis of aplastic patients by serial hematological and bone marrow investigation including blood counts , bone marrow cellularity , scanning with indium and technetium and granulocytic colonies in agar , 8 out of 17 patients had a response to alg as shown by a rise of granulocytes and reticulocytes counts , increase of bone marrow cellularity and number of granulocytic colonies .
