Cytotoxic and radiosensitizing effects of 5-thio-D-glucose on hypoxic cells.

abstract：:It appears reasonable to suggest a histological diagnosis of ependymoma when CT shows an isodense tumor expanding the fourth ventricle or lying within its outlets; when the tumor contains small, round calcifications; and when presentation occurs early in life. An isodense mass occurring in the cerebral white matter, c...
