Abstract


Background.  Associated injury is a worldwide social and economic problem. Age related aspects of endogenous intoxication are not studied comprehensively. Annually, from 44 000 to 65 000 citizens die because of traumatic injuries. As a result, this number increased by 32.6% for the last 10 years.     The detoxification system, as a component of the functional systems of the organism, experiences significant changes in case of polytrauma.

Objective. The study was aimed to discover pathogenetic peculiarities of the multiple trauma in age aspect in different disease periods and to explore the level of endogenous intoxication in this condition.

Methods. The experiments were performed on 72 white male rats aged 3, 6 and 12 months, which underwent simulation of severe skeletal trauma and examination of the contents of middle mass molecules and endogenous intoxication index (markers of endogenous intoxication) in 1, 4 and 24 hours after the associated injury.

Results. The most significant increase of the middle mass molecules was fixed in 24 hours after modeling of severe skeletal injuries in all groups of animals, especially it was the most pronounced in 12-month-old animals. The erythrocyte intoxication index reached the highest level in 4 hours after the injury, its increase was most significant in sexually mature adult animals.

Conclusion. A significant increasing of endogenous intoxication markers in 12-month-old rats, if compared to 3- and 6-month-old animals, can be caused by the decrease in compensatory protection mechanisms.
