Abstract:
Objective To explore the effects of Guilingji on improving learning and memory dysfunction caused by aging. Methods The mouse model of subacute aging caused by D-galactose and the rat model of natural aging were used respectively to imitate learning and memory dysfunction caused by aging. The effects of Guilingji on improving of learning and memory function index were focused in the diving platform experiment and the Morris water maze experiment. At the same time, the effect of that on rat organ index and blood biochemical index were investigated. Results Guilingji can significantly prolong step down latency (P < 0.05) and reduce the number of errors within 5 min (P < 0.05, 0.01) of the model mice. It can shorten positioning navigation escape incubation period (P < 0.01), extend the space exploration quadrant retention time (P < 0.05, 0.01), and increase the number of access to the platform (P < 0.05). Guilingji can increase testicular, thymus and spleen index (P < 0.05) and reduce the ALT content in serum (P < 0.05). Conclusion Guilingji can obviously improve the impairment of learning and memory function caused by aging. It also has some good effects on enhancing immunity, improving reproductive capacity, and protecting liver.
