Acridine orange fluorochrome of nucleic acids was applied to sections of cerebral tissue from 20 patients showing acute or chronic reactive gliosis. The results were compared with the findings in 39 well differentiated and malignant astrocytomas. The orange cytoplasmic fluorescence of ribonucleic acid is lacking in reactive astrocytes of all ages including gemistocytes, but is uniformly present in astrocytoma cells. Acridine orange is a useful supplementary stain for distinguishing between astrocytosis and astrocytoma, paticularly for small cerebral biopsies showing scattered or diffusely infiltrating pleomorphic glial cells.
