[Histochemical and biochemical study of radiation injury of the kidneys in gas hypoxia].

A radioprotective effect of hypoxia was studied in kidney radiation. The use of hypoxic respiratory mixture containing 8% oxygen (the normal content is 21%) enhances kidney resistance to local single and fractionated irradiation. Determination of renal activity of succinate dehydrogenase, lactate dehydrogenase, acid and alkaline phosphatase and urinary N-acetyl-beta-D-glucosaminidase, gamma-glutamyl transferase, alkaline phosphatase, lactate dehydrogenase is recommended as tests for kidney radiation damage.
