Abstract :

Objective: Diet rich in fat is one of the main risk factor for the development of Alzheimer’s disease. Studies have shown that diet rich in fat disrupts memory and learning. The present study evaluates the ameliorative role of Ginkgobiloba and Rosuvastatin against high fat diet induced neurotoxicity in CA1 (Corona Ammonis) region of hippocampus. Materials and Methods: Animals were randomly divided into six groups. Group I received normal diet, Group II received high fat diet, Group III & IV were treated with Ginkgobiloba 50mg/kg and 100mg/kg body weight, and Group V & VI were treated with Rosuvastatin 10mg/kg and 20 mg/kg body weight. All the rats were subjected to spatial learning (Morris water maze). Subsequently, rats were sacrificed and brains were removed. Golgi staining was done and CA1 neurons of hippocampus were traced using camera lucida. Dendritic branching points and dendritic intersections were quantified. Lipid profile and Super oxide (SOD) was also estimated. Results: There was enhancement of spatial learning in treatment group rats. Furthermore, a significant increase in dendritic length and branching points was observed in CA1 region along with significant decrease in the Superoxide dismutase in rats treated with higher dose of Ginkgobiloba and Rosuvastatin. Conclusion: Present study concludes that Ginkgobiloba and Rosuvastatin in higher dose have protective role against high fat diet induced neurotoxicity in CA1 region.
