[The lipid peroxidation processes and the antioxidant system in the dynamics of an experimental Pseudomonas...

Lipid peroxidation and antioxidant defense processes have been studied over the course of experimental Pseudomonas aeruginosa intoxication in albino rats injected with a lethal dose of exotoxin A. The development of intoxication is associated with intensification of lipid peroxidation, manifested by accumulation of malonic dialdehyde and diene conjugates and decreased peroxide resistance of erythrocytes. Superoxide dismutase and catalase activities were inhibited and the concentration of vitamin B dropped. Injection of antioxidant alpha-tocopherol or antihypoxant gutimine at the late stage of intoxication did not notably modify the studied parameters.
