title: Combined application of cytodiagnostic technics to the cerebrospinal fluid.
abstract: The major purpose of the examination of the cells in the cerebrospinal fluid (CSF) is the diagnosis of malignant growths. However, unequivocal tumor cell diagnosis is often problematical, since cells of local origin can also demonstrate considerable proliferative activity and great morphological variety. In these circumstances, it is advisable to evaluate cells from several points of view. One can demonstrate morphological characteristics with panoptic staining and can gain an impression of the RNA content of a cell with acridine orange (AO) fluorescent stain. Quantitative measurements of DNA synthesis in vitro can be made by labelling with tritiated thymidine. Multidimensional cytodiagnosis gives a comprehensive impression of the quality of the cells in question and provides the clinician with information which can be valuable for subsequent diagnostic and therapeutic efforts.
