when 3h-thymidine was administered either intravenously or intra-arterially to 9 patients with gliomas ( 5 glioblastoma multiforme , 3 anaplastic astrocytoma , and one mixed glioma ) shortly before operation , and tissue obtained from the biopsy and , subsequently , at autopsy was examined by autoradiography , it was found that 2 of the glioblastomas diluted out the labelling in the two- to four-month interval between labelling and autopsy , whereas 3 other glioblastomas and the 2 anaplastic astrocytomas retained labelled neoplastic cells in parts of the tumours at autopsy after intervals of from three weeks to five months following labelling .
