To enhance the effect of treatment method of Trichinellosis with mebendazole, lipid peroxidation processes (LPP) in blood of Wistar rats experimentally infected with Trichinella spiralis were investigated. In accordance with health condition of infected rats treated with mebendazole and combination of mebendazole and AKβ vitamin complex, dynamics of the main values of the LPP (such as: activity of superoxide dismutase (SOD) and katalase (CAT) in erythrocytes and malonic dialdehyde (MDA) concentration in blood serum) were analyzed
