Objective: To determine the neuroprotective effects of berberine hydrochloride(BBR) against lead-induced injuries on the hippocampus of rats. Methods: Wistar rats were exposed orally to doses of 100 and 500 ppm lead acetate for 1 and 2 months to develop subchronic and chronic lead poisening models, *** treatment, BBR(50 mg/kg daily) was injected intraperitoneally to rats poisoned with lead. At the end of the experiment, the spatial learning and memory of rats were assessed using the Morris water maze test. Hippocampal tissue changes were examined by hematoxylin and eosin staining. The activity of antioxidant enzymes catalase,superoxide dismutase, glutathione peroxidase, and malondialdehyde levels as parameters of oxidative stress and antioxidant status of the hippocampus were evaluated. Results: BBR reduced cognitive impairment in rats exposed to lead(Phealthy cells in the hippocampus of leadexposed rats(P<0.05). Significant changes in tissue morphology and biochemical factors of the hippocampus were observed in rats that received lead for 2 months(P<0.05). Most of these changes were insignificant in rats that received lead for 1 month. Conclusion: BBR can improve oxidative tissue changes and hippocampal dysfunction in lead-exposed rats, which may be due to the strong antioxidant potential of BBR.
