A study of erythrocyte membrane proteins and urinary polypeptides in conga drumming haemoglobinuria

The erythrocyte membrane proteins and glycoproteins and urinary polypeptides have been examined in a patient exhibiting intermittent pigmenturia associated with conga drumming. 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. 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.
