Introduction: The investigation was aimed at assessment of immunoreactivity in the experimental groups of animals and evaluation of effectiveness of different combinations of pharmacological drugs used in the surgical models for the treatment of acute pancreatitis (AP) of various degrees of severity. Materials and methods: As an object of research, sexually mature male individuals of mongrel white rats were used. Acute pancreatitis of various degrees of severity was caused by either a separate or simultaneous ligation of the pancreas ducts and an intraductal injection of the 50% bile solution in a dose of 0.2 mg/kg. Correction of immunoreactivity indices in the experimental animals was performed with the use of drug combinations producing immunomodulating, antioxidant and membrane protecting effects. Evaluation of the dynamics of immune parameters in rats was carried out using test systems from various manufacturers for laboratory analysis. The obtained findings were statistically processed with descriptive and variation techniques. Results and discussion: The rats developed AP of various degrees of severity, and differently expressed shifts in immunoreactivity indices were observed. Assessment of immune and oxidant indices in experimentally induced acute pancreatitis of moderate and severe states revealed metabolic and immune disorders with anti-inflammatory effects which had various degrees of expression. Combination of immunomodulators, antioxidants and membranoprotectors exerted positive effects on the immunoreactivity state, but insignificantly decreased the mortality rate in the groups of experimental animals. Conclusion: The combination of ferrovir, mexidol, phosphogliv, and its use for moderate and severe degrees of experimentally induced pancreatitis in rats decreases their mortality up to 12.9% and 19.8%. The combination of polyoxidonium, emoxipin and essentiale N exhibits positive clinico-laboratory effectiveness and lowers the mortality indices to statistically significant parameters – 11.8% и 19.6%, correspondingly, with p < 0.05.
