[Detection of a hitherto unknown ninhydrin positive substance in the haemolysate of patients with metachromatic leucodystrophy (author's transl)].

Abstract

A hitherto unknown substance, which appears between glycine and alanine in ion exchange chromatograms, was found in the erythrocyte cold haemolysate of two children with metachromatic leucodystophy; this substance could not be detected in the haemolysates from patients with other (brain) diseases. It would be worthwhile to test for this symptom in confirmed, still active (florid) cases of metachromatic leucodystrophy.
