Results were as follows: 1)In 74 cases, male were 46 and female were 28 cases. The highest incidence by age was noticed as 51.4% in the group under the age of 1 year. 2)Etiologically, hereditary spherocytosis 6, hereditary ellitocytosis 2, PNH 3, DIC 38,hemolytic uremic syndrome 7, mechanical hemolysis 4, autoimmune hemolytic anemia 2,-unclassified 12 cases were present. 3)Bone marrow examination which was performed in 24 cases revealed marked erythroid hyperplasia (mean M/E ratio 1 : 3.4). 4)Coombs test was positive in 2 cases of autoimmune hemolytic anemia. Ham test and sucrose lysis test were positive in 3 cases of PNH. No abnormal hemoglobin was deted. by hemoglobin electrophoresis. 5)RBC osmotic fragility curve in patients with hereditary spherocytosis and elliptocytosis showed marked shift to right side. 6) There were clinical improvement in almost all patients except patients with DIC and hemolytic uremic syndrome. 7) Hemolytic anemia which developed after cardiac surgery occured in 4 eases. 2 cases were not followed up, but another 2 cases were cured by repair of detached patches of VSD.
