The study has shown free radical processes during modeling of Parkinson Disease (PD) with rotenone. We isolated striatum, brainstem, neocortex, cerebellum, spinal cord, thymus, heart, and liver of rats after rotenone injection in the right striatum. The samples were taken on the 5th, 10th and 15th days after the injection. According to chemiluminescence data, the injection of rotenone initiates the disturbance of intensity of free radical processes in striatum at 5th day in a bilateral mode. After this until the 10th day these changes had restoring character, but after 15 days according to chemiluminescence and thio-barbituric acid test disturbance of lipid peroxide oxidation processes occurred. While superoxide dismutase activity has been changed significantly in all studied tissues, especially in the striatum and neocortex. It should be noted that during rotenone model there are no observed clinical symptoms in rats during 1 to 20 days, and the symptoms of the disease are observed approximately 28 days after the injection. This research could help diagnose PD in the early stage of its onset.
