Abstract

Objectives: This study was conducted to determine the effects of Geupunggibodan on brain damage in transient focal cerebral ischemia in rats. Methods: Rats were used for testing in the following three models: Morris water maze, eight-ann radial maze, and histochemistry. Results: In the Morris water maze model, the Geupunggibodan group showed significant decrease in the 3rd, 4th and 6th training sessions compared with the ischemia, group. A retention test in the Morris water maze model was performed on the 7th day without the escape platform. The Geupunggibodan group showed significant increase compared to the ischemia group. In the eight-ann radial maze model, the Geupunggibodan group showed significant decrease in the error rate compared to the ischemia group. In the density of hippocampal CA1 cell of the cresyl violet-stained section, the Geupunggibodan group showed significant increase compared to the ischemia group. Conclusions: These results suggest that Geupunggibodan may have a significant protective effect on brain damage and cognitive dysfunction in transient focal cerebral ischemia.
