The erythrocyte membrane protein pattern of patients with megaloblastic anemia was determined by polyacrylamide gel electrophoresis in sodium dodecyl sulfate. In severe megaloblastic anemia, secondary either to folic acid or vitamin B12 deficiency, the erythrocyte membrane protein pattern was grossly abnormal, lacking bands 1, 2 (spectrin), and 3 and having several diffuse, faster migrating bands. After adequate vitamin replacement therapy, the erythrocyte membrane protein pattern returned to normal. In mild megaloblastic anemia, secondary either to folic acid of vitamin B12 deficiency, and in severe iron deficiency anemia, the erythrocyte membrane protein pattern was normal. Erythrocyte membrane protein pattern of normal membranes did not change after mixing with abnormal membranes before polyacrylamide gel electrophoresis in sodium dodecyl sulfate. Protease activity extracted from membranes of megalocytes was not different from normal. These findings indicate that the erythrocyte membrane protein pattern is abnormal in severe megaloblastic anemia and that this abnormality is not secondary to increased activity of the endogenous erythrocyte membrane proteinase.

To investigate the syndrome of acute intravascular hemolytic anemia in the black rhinoceros (Diceros bicornis), laboratory techniques used in the differential diagnosis of hemolytic anemias were performed on blood samples from 6 black rhinoceroses: 3 nonrelated healthy rhinoceroses, 1 rhinoceros with iron deficiency anemia, and 2 rhinoceroses with intravascular hemolysis. Osmotic fragility, erythrocyte membrane protein composition, hemoglobin electrophoresis, and hemoglobin stability did not distinguish between healthy and affected (anemia or hemolysis) rhinoceroses. Polyclonal antiglobulin reagents were prepared in rabbits, using whole rhinoceros serum and purified rhinoceros immunoglobulin G. These reagents were nonreactive against erythrocytes of the healthy and iron-deficient rhinoceroses. Reactions with RBC from the rhinoceros with fatal hemolytic anemia indicated increased membrane coating by the third component of complement; this was not evident in a second rhinoceros that survived a hemolytic event.
