The macromolecular AGAG in the urine of patients with Werner's syndrome were analyzed by enzymatic methods after digestion with chondroitinases and Streptomyces hyaluronidase. The molecular weight-dependent distribution of the urinary AGAG has been determined by gel filtration on a Sephadex G-100 column. The distribution of HA and HS was predominant in the macromolecular fractions. Chondroitin sulfate isomers were prominent in the low molecular weight fractions but the ratio of the 4-type to the 6-type increased with decreasing molecular weight. These observations indicated that Werner's syndrome is a metabolic disorder of the molecular weight-dependent AGAG composition.

We performed morphological studies of skin and measured glycosaminoglycans in the urine from patients with sporadic amyotrophic lateral sclerosis (ALS) and control subjects. The wide spaces separating collagen bundles reacted strongly with alcian blue stain in ALS patients and stained more markedly as ALS progressed. Staining with alcian blue was virtually eliminated by Streptomyces hyaluronidase. The urinary excretion of hyaluronic acid (HA) (mg/day) was significantly increased (P < 0.01) in ALS patients compared with that of control subjects, and there was a significant positive correlation between the excreted amount of HA and the duration of illness in advanced ALS patients with a duration of more than 2 years from clinical onset (r = 0.72, P < 0.02). We suggest that sporadic ALS includes a metabolic disorder of HA in which an accumulation of HA in the skin is linked to an increased urinary excretion of HA.
