The aim of the study was to describe the dynamics of the morphological changes in the liver and small intestine of laboratory animals during acute radiation in the biocorrection state. It was found that significant morphological changes were observed in the liver of laboratory animals after acute radiation in both groups, and the intensity of morphological changes was lower in group 2 with prior biocorrection than in group 1 without biocorrection. A similar situation was observed when studying the histological picture of the small intestine of these white-bred rats, the intensity of morphological changes was lower than in white-bred rats that did not receive the biologically active supplement "Lactopropolis-AWL".
