Abstract:
Objective To evaluate the effects of extractive from Gastrodiae Rhizoma on acquisition, consolidation and retrieval of learning-memory function in mice;To provide some reference for clinical research and development of new drugs.Methods Male Kunming mice were randomly divided into control group, model group, positive control group and Gastrodia extractive group. Positive control group and Gastrodia extractive group were given gavage by using relevant medicine 0.2 mL/10 g, and the control group and model group were given gavage with the same amount of distilled water for 16 days. After receiving gavage for continuous 11 days, memory acquisition barrier model was induced by scopolamine;memory consolidation barrier model was induced by chloromycetin;memory retrieval barrier model was induced by EtOH. The learning-memory function was reviewed by escape latency and spatial search distance. The quadrant and distance search time percentage was detected through directional navigation test and spatial probe test in Morris water maze.Results Extractive from Gastrodia Rhizoma shortened the time for acquisition, consolidation and retrieval of learning memory about escape latency and spatial search distance (P<0.05,P<0.01), and the quadrant and distance search time percentage were prolonged (P<0.01).Conclusion Extractive from Gastrodia Rhizoa can effectively improve the acquisition, consolidation and retrieval of learning-memory function in mice.
