    Notes: Summary Polyamine levels have been studied in brain tumor patients. We focused our study on the relationship between tumor, cerebrospinal fluid (CSF) and red blood cell (RBC) polyamine levels. Our results are the following: (1) Polyamine levels in CSF are consistently increased, whatever the histological type may be. (2) The highest tumoral concentrations are found in medulloblastomas. (3) In glioblastomas, the RBC spermidine levels are higher than in the other types of tumors and there is a highly significant correlation between the spermidine/spermine ratio in tumor and RBC. Therefore, RBC polyamine determinations might be of clinical interest in the monitoring of patients with glioblastomas.

    Notes: Summary 137 samples of intracranial tumours have been studied in proton NMR spectroscopy. T1 and T2 relaxation times are above those of normal grey and white matter. Differential diagnosis between benign and malignant brain tumours does not seem feasible upon proton T1 and T2 alone. Histological correlations allowed us to specify secondary changes accounting for T1 and T2 variations (oedema, microcyst, stroma reaction, necrosis).
