- Abstract: Objective: To investigate the effects of Kaixin Powder on learning and memory, ATP/AMP ratio, GABA andiNOS levels in rats with multiple infarct dementia. Methods: The rat model of multi-infarct dementia was established bymicro-thromboembolism. Morris water maze and opening experiment were used to evaluate learning and memoryfunction. The pathological changes of hippocampal CA1 area were evaluated by HE staining. The contents of ATP andAMP in brain tissue were determined by HPLC. The content of γ-aminobutyric acid and iNOS in peripheral blood weredetected by ELISA kit. Results: Compared with the rats of model group, rats of Kaixin Powder group can significantlyshorten the escape latency, increase the number of crossing platforms, Results: Compared with the model group, increasethe standing times in the opening experiment, prolong the exercise time, shorten the resting time, improve the nerve celldamage in the hippocampal CA1 area, and significantly increase the ratio of ATP/AMP of brain tissue, decreased brainGABA content and serum iNOS content (P < 0.05) . Conclusion: Kaixin Powder has the effect of improving learning andmemory function and abnormal motor behavior in rats with multiple infarct dementia. The mechanism is related toreducing GABA and i NOS content in brain tissue, increasing ATP/AMP ratio in brain tissue and improving energysupply in brain tissue.
