A study of Erythrocyte Membrane Proteins and Urinary Polypeptides in Conga Drumming Haemoglobinuria

1. The erythrocyte membrane proteins and glycoproteins and urinary polypeptides have been examined in a patient exhibiting intermittent pigmenturia associated with conga drumming. 2. Significant excretion of haemoglobin, albumin and probably erythrocyte carbonic anhydrase but not myoglobin occurred during the acute phase of the conga drumming-induced pigmenturia. This usually ceased within 24-48 h. 3. We found no evidence of aberrant erythrocyte membrane components on electrophoresis with either protein staining or a range of 125I-labelled lectins used for detection.
