title: [Lysosomal-cation test and the prospects of its use in pathomorphological and laboratory diagnostic practice].
abstract: A cytochemical lysosome-cation test is proposed as suitable for use in diagnostic laboratories. The test is based on the detection of cationic protein and determinations of the fate of phagocytized and extracellular bacteria in inflammation foci. A method for simultaneous cytochemical detection of myeloperoxidase and cationic proteins in neutrophilic and eosinophilic granulocytes was developed. Using this method, a previously unknown variety of lysosomal granules devoid of peroxidase was detected in neutrophilic promyelocytes. The lysosomal cation test was shown to be useful for improved morphological diagnosis of leukemias, for the determination of the fate of phagocytized and non-phagocytized bacteria in inflammation foci, and of the level of nonspecific and infection resistance of the host.
