[Ultraviolet spectrophotometry of the cerebrospinal fluid in the differential diagnosis of strokes].

The authors describe the possibility of using the results of ultraviolet spectrophotometry of the cerebrospinal fluid (CSF) for the differential diagnosis of ischemic, hemorrhagic and mixed cerebral strokes. It was found that repeated examinations may be of a definite prognostic value. A correlational analysis showed that the greatest effect on the optical density of the CSF in cases of hemorrhagic strokes is exercised by protein and bilirubin and in cases of ischemic strokes by protein and aspartate aminotransferase (AST).
