Histograph

Tumour tissue oxygenation has been measured in man during carbogen breathing (95% O2, 5% CO2) using a commercially available polarographic electrode system (Eppendorf p02 histograph).

FSaII tumours grown s.c. in the leg of C3H mice and R3230 AC tumours grown s.c. in the leg of Fischer rats were heated with a water bath and the tumour pO2 was determined with an Eppendorf pO2 histograph.

Until now a total of 38 Patients with malignancies of the head and neck were examined. Tumor tissue pO₂ was measured using a pO₂-histograph.
