[Reference values of Na(+) and Cl(-) concentrations in adult sweat].

The results of the investigations to reference values for Na(+)- and Cl(-)-concentrations in sweat of adults are as follows: The normal range of electrolyte values in sweat in adults is up to 70 mmol/l (Na+) and 55 mmol/l (Cl-) respectively in infants (40 mmol/l for Na+ and Cl-). There are no sex and age differences. Adults with chronical bronchitis and bronchiectasis don't show different results in comparison with healthy persons.

[Immunoglobulin content in bronchoalveolar lavage fluid in sarcoidosis].

The amount of albumins and immunoglobulins in the broncho-alveolar lavage fluid of sarcoidosis patients were measured and correlated with cellular activity parameters in sarcoidosis. It could be shown that IgG and IgA, related to albumin, were increased in comparison with serum while the IgM fraction was decreased. In general, the highest values of immunoglobulins were found in active sarcoidosis.

[Bronchoalveolar lavage in patients with sarcoidosis--methodologic aspects of the collection, immunologic characterization of lymphocytes and studies of immunoglobulin content].

The activity of alveolitis in 25 patients with pulmonary sarcoidosis was determined by analysis of T-Lymphocytes and their subpopulations collected by broncho-alveolar lavage. The characterization of the lymphocytes was performed with monoclonal antibodies (BL-series). An amount of T-lymphocytes higher than 28% of all cells and a proportion of T4/T8-lymphocytes of 8:1 and over are signs of the activity of the alveolitis and an indication for corticoid therapy.
