Abstract
The diagnostic significance of the cerebrospinal fluid (CSF) was investigated in autopsy cases and clinical cases of neonatal intracranial hemorrhages (ICH).1. Of the 24 term and premature cases with subdural hemorrhage, 4 term and 1 premature infants were accompanied with subarachnoideal or ventricular hemorrhage which might cause bloody CSF. Eighty to eighty five percentage of 66 premature and term autopsy cases with ICH also had subarachnoideal or ventricular hemorrhage.2. The red cell count in CSF of autopsy cases with intracranial hemorrhage was not parallel to pathological findings of intracranial hemorrhage.3. The protein amount and LDH ac tivity in CSF of clinical and autopsy cases with ICH were not significantly higher than control cases without ICH.4. Benzidin reaction in CSF of cases with IC H was slightly positive within one day after the onset of hemorrhage, and was more strongly positive 2 or 3 days later.5. The concentration of CSF bilirubin and hemoglobin were m easured by spectrophotometric
