Keywords: duodenum, thermal trauma, diabetes.


Currently, severe thermal injury is becoming one of the most important problems of practical medicine. Diabetes is also recognized as another global medical and social challenge of our century. The emergency situation for the treatment and prevention of the consequences of these pathologies is a consequence of the lack of a reliable theoretical basis for solving specific clinical problems regarding the course of burns, diabetes and their complications. The aim of the study is to establish the patterns of structural changes in the mucous membrane of the duodenum after burn injury of the skin of rats under conditions of experimental diabetes mellitus. The study was performed on 63 laboratory white adult male rats weighing 180-210 g, which were divided into 3 groups: intact animals, rats with skin burns and rats with skin burns on the background of diabetes. The model of experimental diabetes mellitus was reproduced by administering Streptozotocin to rats intraperitoneally once at a dose of 50 mg/kg, pre-dissolved in 0.1 M citrate buffer solution (pH=4.5). The control of the development of hyperglycemia in the experimental groups was the level of glucose in the blood 24.24±0.79 mmol/l. In the control group this index was 8.03±0.4 mmol/l. Rats with skin burns revealed destructive manifestations, which are accompanied by an active inflammatory reaction and corresponding necrotic changes, while rats with skin burns on the background of diabetes mellitus pathological processes are not just “summed up”, but in some way adaptively modified with the involvement of stress mechanisms of the endoplasmic reticulum and associated autophagy.
