Alkaline phosphatases in alveolar secretions from the lungs of patients with pulmonary alveolar proteinosis have been studied. A soluble form of alkaline phosphatase was isolated from the secretions and characterized. The extracellular enzyme had a pH optimum at 9.95; was stimulated by Mg2+, Ni2+,
Cytological, cytochemical and immunopathological investigations were carried out at lung washings in a case of pulmonary alveolar proteinosis. There was an increased activity of alveolar epithelial cells of type II (AEZ II) with increased production of surfactant lipids. Abundant lipids of the
In recent years the determination of serum enzyme activities has played an increasing role in clinical chemical diagnosis. Because the enzyme composition of single organs is qualitatively and, to a certain extent, quantitatively similar, the diagnostic value of enzyme activity determinations is
