The aim of this study is to investigate the effects of acupuncture on cognitive deficits and oxidative stress in cerebral multi-infarction rats. The results showed that acupunctural treatment attenuated memory impairment induced by cerebral multi-infarction, as evaluated by shortened escape latency and increased swimming time of rats with memory impairment in the target quadrant. The data additionally suggested that acupunctural treatment ameliorated oxidative injuries induced by cerebral multi-infarction by increasing the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the hippocampus. Further investigation by in situ hybridization and immunohistochemistry revealed that acupunctural treatment significantly increased the expression of CuZnSOD mRNA and protein in the hippocampus of the impaired rats. The findings demonstrate that acupuncture can exert beneficial effects on spatial memory and antioxidant status of cerebral multi-infarction rats. (C) 2005 Elsevier Ireland Ltd. All rights reserved.
