title: Sanfilippo disease type B: enzyme replacement and metabolic correction in cultured fibroblasts.
abstract: alpha-Acetylglucosaminidase, purified from human placent, corrected the defect in mucopolysaccharide degradation when added to culture fibroblasts from patients with Sanfilippo disease type B. A small cellular concentration of enzyme gave a large corrective effect. The half-life of disappearance of enzyme activity was 4 to 7 days.
