cell kinetics studies of patients with various gliomas published in the past decade have shown that the average labeling index ( li ) obtained from a pulse of 3h-thymidine is very high in medulloblastomas ( 12.0 % +/- 1.3 % , standard error of the mean ) and glioblastoma multiforme ( 9.3 % +/- 1.0 % ) , low in well differentiated gliomas ( less than 1 % ) , and intermediate in anaplastic astrocytomas ( 4.0 % +/- 0.8 % ) .
