title: [Experimental evaluation of the role of blood flow inhibition in hyperglycemia-enhanced radiation damage to tumors].
abstract: The authors provided experimental assessment of the role of the blood flow inhibition in enhancement of radiation injury to tumors using short-term hyperglycemia. Experiments on mice with Ehrlich solid carcinoma showed the dependence of a rise of the antitumor effect of preceding radiation induced by glucose and glucose combined with mexamine on a degree of the blood flow inhibition under the influence of these modifying agents. It was established that a considerable enhancement of radiation injury occurred but in such tumors where short-term hyperglycemia and mexamine decreased the blood flow level not less than 5-10 fold as estimated by 133Xe clearance. The results of the above experiments showed that noticeable inhibition of the blood flow in tumors was a necessary though, probably, not the only condition for a high efficacy of short-term hyperglycemia used as an adjuvant to radiotherapy.
