    Abstract:
    Cerebellar ataxia (CA) is regarded as a miscellaneous cluster of brain disorders related to the cerebellum. Resveratrol is a naturally occurring polyphenolic compound. Previous reports suggest that resveratrol confers neuroprotection in various animal models of brain damage. Indeed, we considered it invaluable to investigate whether a treatment with resveratrol has a therapeutic role against CA induced by 3-acetylpyridine (3-AP) in rats. In addition, no investigation has examined neuroprotective effect of resveratrol in rat model of CA. Initially, 3-AP administration generated CA rat models followed by intraperitoneal injection with resveratrol. Then, motor performance and muscle electromyography (EMG) activity were assessed. Moreover, the anti-apoptotic role of resveratrol in CA and its relationship to protection of Purkinje cells were explored. According to what we have found, resveratrol administration improved the muscle activity and movement coordination in 3-AP-lesioned rats. Also under resveratrol treatment, the total number of the Purkinje neurons increased whereas a reduction in apoptotic bodies was observed. In conclusion, post-treatment with resveratrol evidently ameliorated motor performance as well as muscle activity accompanied by a protection of Purkinje cells in ataxic rats.
