## Abstract Several human prostatic tissues have been examined for possible particles and associated DNA polymerizing activity generally associated with the Cโtype RNA tumor virus family. Partially purified tissue extracts, when centrifuged to equilibrium in sucrose gradients, yield fractions which

## Background: In this study, telomerase activity in human brain tumors was analyzed. ## Methods: Telomerase activity was examined in 41 brain tumor cases (20 of glioblastoma multiformes [gbms] [14 primary tumors and 6 recurrent tumors], 3 anaplastic astrocytomas [aas], 4 low grade astrocytomas [
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 ty
