Abstrakt:	Objective: Aim: The aim of the study was to determine the impact of cranioskeletal trauma (CST) on the development of endogenous intoxication syndrome in rats of different ages. Patients and Methods: Materials and Methods: The experiments involved 147 white male Wistar rats of different age groups. The first experimental group included sexual immature rats aged 100-120 days. The second group includes sexually mature rats aged 6-8 months. The third group included old rats aged 19-23 months. In all experimental groups, CST was modelled under thiopentalonatrium anaesthesia. The control rats were only injected with thiopentalonatrium anaesthesia. The animals were withdrawn from the experiments under anaesthesia after 1, 3, 7, 14, 21 and 28 days by total bleeding from the heart. In blood serum, the content of fractions of molecules of middle mass was determined at a wavelength of 254 and 280 nm (MMM254, MMM280). Results: Results: As a result application of CST in rats of different age groups, an increase in the serum content of MMM254 and MMM280 was observed with a maximum after 14 days and a subsequent decrease by 28 days. At all times of the experiment, the indicators were statistically significantly higher compared to the control groups. The degree of growth of the MMM254 fraction after 1, 7 and 14 days was statistically significantly higher in sexual immature rats, and after 21 and 28 days - in old rats. In old rats after 21 and 28 days of the post-traumatic period, the content and degree of growth of the MMM280 fraction in the blood serum were also significantly higher. Conclusion: Conclusions: Modelling of CST in rats of different age groups is accompanied by the development of endogenous intoxication syndrome, which is manifested by the accumulation of MMM254 and MMM280 fractions in the blood serum with a maximum after 14 days of the experiment. The content of the serum fraction of MMM254 in sexual immature rats in the dynamics of experimental CST exceeds other age groups after 1, 7 and 14 days, in old rats the content of the studied MMM fractions is significantly higher after 21-28 days.
