Abstract
Summary
White blood cells, mainly lymphocytes, in culture from patients with cystic fibrosis, showed a diminution of the activity of beta-glucuronidase. The mean activity of this enzyme in cystic fibrosis was 30% lower than in the controls at 5 days of culture and 35% lower than the controls at 7 days. Acid phosphatase activity in cystic fibrosis cultures was not significantly different from control cultures, while beta-acetylglucosaminase activity was significantly decreased in cystic fibrosis cultures of 7 days compared to control cultures.
