Abstract
The aim of the study was to determine the bronchoalveolar lavage (BAL) cell differentiation and the activity of beta-glucuronidase and N-acetyl-beta-D-glucosaminidase in alveolar macrophages. In 12 patients with systemic sclerosis (SS), 4 with systemic lupus erythematosus and 4 healthy controls BAL was performed. The activity of beta-glucuronidase and N-acetyl-beta-D-glucosaminidase was measured semiquantitative by means of cytochemical methods. Lymphocytes and neutrophils in BAL cell differentiation are increased, also the activity of beta-glucuronidase. The activity of N-acetyl-beta-D-glucosaminidase is decreased in SS and SLE in comparison with controls. The activity of beta-glucuronidase seems to be a marker of activity of alveolar macrophages in SS and SLE.
