Abstract
The aim of this study was to develop a hemostatic agent with anti-adhesive properties and to study its effect on liver morphology, metabolic activity and hepatocyte regeneration in experimental liver injury.
Methods. In 60 rats following experimental resection liver injury, the time of bleeding and the volume of blood loss were determined. Histological preparations were used to study the size of hepatocytes and their nuclei, the content of glycogen (PAS-reaction), the number of binucleated hepatocytes and the expression of Ki-67.
Results. Compared with the control, an agent based on 6% sodium carboxymethylcellulose gel and 5% aminocaproic acid effectively and reliably reduces the bleeding time by 72% (217.91 s), the volume of blood loss by 74.7% (372.85 mg) (p ≤ 0.01) and the degree of blood filling of the sinusoid liver capillaries. In addition, the use of the novel gel prevents the adhesion formation. It stimulates mitotic activity of hepatocytes, accompanied by an increase in the number of binucleated hepatocytes and Ki-67 expression. By the 14th day, this activity significantly decreases. Hypertrophy of hepatocytes and their nuclei is observed by the 7th and 14th days of the experiment. This indicates both an increase in the metabolic activity of hepatocytes and intracellular regeneration. The use of the hemostatic gel does not alter the glycogen-storing function of hepatocytes, which indicates the lack of pronounced hypoxia due to effective control of bleeding.
Conclusion. The local hemostatic gel based on 6% sodium carboxymethylcellulose gel and 5% aminocaproic acid can be recommended for local bleeding control in liver injuries and surgery.
