1. Test method
80 healthy male SD rats were randomly divided into a normal control group, a model group and an experimental group (example 3 group, example 4 group), and 20 rats were each group. The model group and the experimental group of rats establish a depression rat model by combining isolated culture with chronic mild unpredictable stimulation according to a reference method, and the rats are normally bred in a blank control group. During modeling, the test group was gavaged with 20mg/kg of the intestinal mucosal extract obtained in examples 3 and 4, and the control group and the model group were gavaged with 0.9% NaCl in equal amounts for 4 weeks. The model group rats were associated with typical depressive symptoms of water intake, decreased exploratory behavior, weight loss, decreased interest, dull hair color, etc.

experimental example 2 Effect of the composition on improving depressive behavior in manic model rat
1. Molding method
80 healthy SD rats were divided into a normal control group, a model group, and an experimental group (example 3 group, example 4 group) by a random number table method, and 20 rats were each group. The model group and the experimental group adopt the improved multi-platform sleep deprivation method (MMPM) to establish a mania model (refer to the method of reference literature on the influence of the change of the neuron-type nitric oxide synthase expression after sleep deprivation and the refreshment). Rats can eat and drink water on the platform by themselves, and the water in the rat box is changed every day. Rats were acclimated on the platform for 1h each day 1 week prior to the experiment. After the experiment started, rats were all on the platform except the water tank for water change, for a total of 7 days. The normal control group adopts a mouse box with the same size as the model group, but a platform is not placed at the bottom of the mouse box, a fine wire mesh is placed on the bottom of the mouse box, the rat is placed on the mesh, water is placed under the mesh, and the water is up to 1cm below the mesh, so that the rat can obtain normal sleep, and other conditions are the same.
2. Intervention method
The blank control group and the model group are not subjected to intervention treatment, and the experimental group is respectively administered with the intestinal mucosa extracts obtained in the example 3 and the example 4 by intragastric gavage at the dose of 20mg/kg for intervention treatment, wherein the intervention time is 4 weeks.
3. Detecting the index
(1) Rat autonomic behavior determination:
using the Open-Field method (OIT), one rat at a time was placed in the Open-box center square for 3 min. The horizontal score is the number of squares passed by the rat horizontally, 3 or 4 claws of the rat are specified to enter the same grid and is marked as l score; the vertical score was given by 2 hind paws supporting the body and 2 forepaws leaving the floor, with 1 score for each 1 leave.
(2) Sleep latency determination
Continuously depriving the rat of sleep for 7d, and recording the time (namely the sleep latency) from the beginning of the lower platform of the rat to the 1 st sleep of the rat after the molding is finished, wherein the successful molding of the mania is carried out if the time is more than 30 min. The rat falls asleep is defined behaviorally as the rat closes eyes and remains still in bed for 30s or more.
(3) Statistical method
The analysis was performed using SPSS20.0 statistical software. The data are expressed as means ± standard deviation, single-factor analysis of variance (ANOVA) is used for multiple comparisons, and q-test is used for pairwise comparison. P <0.05 is statistically significant for the differences.
4. Results
(1) Comparison of general behavior of rats in each group
Model group: after 1d of sleep deprivation, the sleep shows excitement, and the sleep shows disorderly movement among different platforms, is sensitive to external slight acousto-optic stimulation, and shows a frightened state to the acousto-optic stimulation; after 3 days of sleep deprivation, the patient is dull, slight twitching of the muscles of the head and the face is accompanied by movement of the beard, the patient crouches on a platform, falls into the water repeatedly due to dozing, climbs the platform after waking up, the activity and the food intake are reduced, and after stimulation, the patient has aggressive behaviors such as indiscriminate biting and the like. Sleep deprived 5-7d rats were mentally impatient, had little feeding activity, had generalized hair sticking, were extremely irritable, had increased aggressive biting behavior, and resulted in death of 4 rats during biting.
Blank control group: no manic manifestations of the model group.
Experimental groups: compared with a model group, the manic performance is obviously reduced, and no animal is killed due to the bite behavior.
The results show that the small intestinal mucosa extract can obviously improve the irritability and the aggressive manic state of the manic rats.
(2) Comparison of autonomic behavior results for groups of rats
Compared with the normal control group, the horizontal activity score and the vertical activity score of the rats in the model group are remarkably reduced (P <0.05), and the model building is suggested to cause the reduction of the horizontal activity and the vertical activity of the rats. Compared with the model group, the score of the horizontal activity and the score of the vertical activity of the small intestine mucosa extract group are both obviously improved (P <0.05) compared with the model group, which indicates that the small intestine mucosa extract obviously improves the mania state of the maniac rats. The specific results are shown in Table 3.
