FEATURES OF BILIARY TRACT FUNCTION OF THE LIVER WITH MECHANICAL TRAUMA OF VARYING SEVERITY AGAINST THE BACKGROUND OF POISONING WITH SALTS OF COPPER AND ZINC

Abstract

Skeletal trauma causes significant biliary tract violations of the liver. Excess copper ions and zinc reduces biliary function of the liver.
 The aim of the study – to find out the pathogenetic features of liver damage in the case of mechanical injury of varying severity in the presence of excess copper and zinc ions in the body and its antidote therapy.
 Material and Methods. Experiments were performed on 150 non-linear white male rats weighing 180–200 g. In the context of chronic intoxication with copper and zinc sulfates, they simulated skeletal trauma of varying severity. In animals after 1, 3 and 7 days of post-traumatic period, bile duct function of the liver was studied. The received digital data was subject to statistical analysis.
 Results and Discussion. Against the background of a medium-degree injury, the indicator varied wavy: after 1 day it increased significantly in relation to the control group (by 32.7 %, p<0.05). After 3 days it significantly decreased and became 17.6 % less than control (p<0.05). After 7 days, it continued to remain at the same level (p<0.05 for control). In conditions of excessive ion exchange of copper and zinc in 1 day the indicator was at the control group level (p>0.05). However, after 3 and 7 days it was significantly lower than the reference level (27.8 % and 24.3 % respectively, p<0.05). In these conditions, after 1 and 3 days, the indicator was statistically significantly lower on the background of excessive intake of copper and zinc ions (31.6 % and 12.4 % respectively, p<0.05).
 Conclusions. Skeletal trauma causes a significant violation of biliary tract function of the liver. At a trauma of a light degree without intoxication copper and zinc salts in 1 day the index to 7 days increases. While in the middle and severe injuries, after 1 day it is greater than control, but in the future it is lower than the control group. Excessive intake of copper ions and zinc contributes to a decrease in the studied index from 1 to 7 days, and with the trauma of moderate and severe severity of the lungs 3 and 7 days it becomes significantly lower than in the nontoxic group.
