Abstract

Objective. To study the level of endogenous respiration of the small intestine mucosa of experimental animals after exposure to external irradiation at a dose of 0.5 and 1.0 Gy.Materials and methods. The study was conducted on white male outbred rats weighing 180-200 g. The animals were irradiated once in the “IGUR-1” unit, 137Cs source, dose rate 0.92 Gy/min. The parameters of tissue respiration were studied by polarographic method using Record-4 device (RF) in a 2 ml cell with a closed platinum Clark electrode at 25°C.Results. It was shown that changes in respiratory activity over time are non-monotonous. This confirms the high sensitivity of the small intestine to radiation exposure.Conclusion. The level of endogenous respiration of the small intestine mucosa can be one of the criteria for assessing the energy status of the tissue after irradiation.
