Objective to investigate the radiomodifying properties of N-stearoilethanolamine (NSE) in experiment under different conditions of a combined impact of ionizing radiation and stress.
Methods: biochemical, statistical.
Results. The radiomodifying properties of N-stearoilethanolamine were revealed under different conditions of a combined impact of ionizing radiation and stress according to the indices of plasma concentrations of TBA-active products, nitrite-anions and catalase activity.
Conclusions. The radioprotective properties of NSE at a dose of 10.0 mg/kg before and after a single total 6.0 Gy irradiation of animals. The radioprotective properties of NSE are identified at a dose of 10.0 mg/kg of animal bodyweight before and after stress. The radiosensitizing properties of NSE occur upon the drug administration in a dose of 10.0 mg/kg before the combined impact of 6.0 Gy ionizing radiation and stress.

Key words: male rats, N-stearoilethanolamine, ionizing radiation, stress, TBA-active products, catalase, nitrite anion.
