The effect of gas hypoxia (10% O2) and dextran sulfate on the radiosensitivity of the stem cells of the intestinal epithelium in mice]

Injection of dextran sulphate before irradiation was shown to protect jejunal epithelium stem cells (D0 increased from 1.13 to 1.82 Gy). The protective effect of a combination of dextran sulphate and gas hypoxic mixture (10% O2) did not exceed that of the administration of the gas hypoxic mixture (10% O2) alone.
