antagonizing state anxiety in ratsSeventy male SD rats were selected and adapted to the environment for 7 days.They were randomly divided into a model control group,a blank control group,and different doses of wild jujube administration groups: wild jujube 1,wild jujube 2,wild jujube 3,wild jujube 4,wild jujube 5 Groups of 10 animals per group.The model control group and the different doses of jujube administration group were placed in a conditioned fear stimulus box to give sound stimulation(75 d B;1000 Hz;5 s)and electrical stimulation(0.5 m A;1s)during the last 1s of the sound signal.The interval between the two stimulations was 60 s,and a total of 15 cycles were performed.The blank control group was given only sound stimulation but not electric stimulation.According to the above method,the model was made for 4 consecutive days.On the day after the model was replicated,the different doses of jujube administration group were given 1.25 g/kg,2.5 g/kg,5 g/kg,10 g/kg,20 g/kg(equivalent to crude drug amount)via intragastric administration.The lyophilized powder of wild jujube was administered continuously for 10 days.The model control group and the blank control group
