Introduction. The development of multiorgan dysfunction and insufficiency is one of the serious complications of severe multiple and combined lesions. In their pathogenesis, a key role is played by secondary lesions of organs remote from the site of direct injury, which is caused by the systemic response of the body to inflammation and is a characteristic feature of traumatic disease. As a model of the development of organ damage in experimental polytrauma, the biliary function of liver is often investigated. However, the features of systemic disorders, in particular, the biliary function of liver, in conditions of severe skeletal injury, depending on the resistance to hypoxia, have not been studied enough.Purpose: to determine the dynamics of biliary function of liver in case of cranioskeletal trauma complicated with blood loss among rats with different resistance to hypoxia during the early period of traumatic disease and to evaluate the effectiveness of thiocetam in the correction of identified disorders.Materials and methods. 108 nonlinear white male rats weighing 180-200 g were used in the experiments. Previously, individual resistance to hypoxia was determined, rats were divided into two groups: with high- and low-resistance (HR and LR) animals to hypoxia. Subsequently, HR and LR rats were divided into 4 groups: one control and three experimental. Under conditions of thiopentale sodium anesthesia (40 mg kg-1) the first experimental group HR and LR of rats was had cranioskeletal trauma, the second - acute blood loss in the amount of 20-22% of circulating blood volume, the third experimental group after application of cranioskeletal injuries and acute blood loss in order to correct HR and LR-rats were thrown Thiocetam intraperitoneally, dose 250 mg kg-1 of body weight 1 time per day. Animals of the control and experimental groups in 1, 3 and 7 days after injury were catheterized the common bile duct, collected bile, in which the content of total bile acids was determined.It was found out that laboratory white rats, which are genetically different in resistance to hypoxia, also differ in the intensity of biliary function of liver. Among HR rats, the bile content of total bile acids was higher than that among LR rats. Under the influence of cranioskeletal injury, the bile content of total bile acids decreased among both HR and LR rats. Despite the lower initial content of total bile acids in the bile of LR rats, under the influence of cranioskeletal trauma in this group, the degree of the studied indicator reduction was significantly greater than among HR rats, indicating greater sensitivity of LR rats to pathogens of traumatic disease, which lead to damage to the microsomal monooxygenase system of hepatocytes. Under the conditions of acute blood loss additional modeling, the disorders were more visible, but the result was statistically significant only among LR rats in 3 days of the experiment. In addition, LR rats had a greater degree of reduction of the studied indicator in 3 and 7 days of the experiment. Under the influence of seven-day-usage of Thiocetam in the groups of LR and HR rats with cranioskeletal trauma, the violation of total bile acids content in the bile became significantly lower compared to animals without correction. A similar result was found under conditions of additional acute blood loss. Under these conditions, the degree of increase of total bile acids content in the bile was greater among LR rats than among HR rats, which indicates a higher efficiency of Thiocetam among LR rats.Conclusions: 1. The content of total bile acids in the bile among intact HR-rats is significantly higher than among LR-rats. Under the influence of cranioskeletal trauma, the content of total bile acids in the bile is reduced compared to the control, but the degree of reduction is significantly greater among LR rats after 7 days of the experiment. Complication of cranioskeletal injury with acute blood loss causes a significantly greater reduction in the bile content of total bile acids among LR rats compared with HR rats after 3 and 7 days of the experiment. The use of Thiocetam is accompanied by a decrease of liver biliary dysfunction, which is more visible among LR rats with acute blood loss.
