Abstract:
Objective To explore the effeet of Zizyphus jujubekernelfreeze - dried powder on sleep and wakefulness and energy metabolism rate in rats under 24 h eontinuous darkness and its mechanism. Method U- sing the eortieal eleetroeneephalography method and the experimental animal monitoring system (CLAMS) and taking the time of wakefulness and sleep as well as the number of activities, food intake, and caloric pro- duetion as indicators to explore the funetion of it on improving energy metabolism rate. Theenzyme - linked immunoassay was used to determine the changes in the eontent of LEP, POMC, and NPY involved in energy regulation in the hypothalamus, so as to study the energy change mechanism of it. Result Compared with the DD group, the MAT group had redueed daytime awakening time, increased sleep time, deereased aetivities, no signifieant differenee in food intake, and inereased caloric production. There was no significant difference in night awakening and sleep time, no significant difference in the number of activities, reduced food intake , and increased caloric production. The weight gain of rats decreased; Compared with the DD group, the LEP content in the hypothalamus of the MAT group increased, the POMC content increased and the NPY content decreased. Conclusion By increasing LEP, POMC content and decreasing NPY content in hypothalamus , Zizyphus jujubekemelfreeze - dried powder collected the disturbance of sleep and wakefulness state and abnormal energy metabolism rate of rats caused by 24 h continuous dark condition.
