[0057] Elevated plus maze test
[0058] The elevated plus maze includes two mutually perpendicular open arms (30 cm long, 6 cm wide) and two closed arms (30 cm long, 6 cm wide), the upper part of the closed arms is open, and there is a 5 cm × 5 cm open part in the center. The maze is 50 cm above the ground. 100 ICR mice were taken, adaptively fed for one week, and randomly divided into 10 groups, each with 10 mice, namely blank control group (normal saline solution), diazepam group (5 mg / kg), Example 1 group (300 mg / kg), Example 2 group (300 mg / kg), Example 3 group (300 mg / kg), Comparative Example 1 group (300 mg / kg), Comparative Example 2 group (300 mg / kg), Comparative Example 3 group (300 mg / kg), Comparative Example 4 group (300 mg / kg), Comparative Example 5 group (300 mg / kg). The mice were given drugs by gavage for 14 days, once a day. 60 minutes after the last drug administration, the mice were placed in the central open part of the elevated plus maze, with their heads facing the closed arms. The DigBehv Animal Behavior Analysis System 2.0 automatically recorded the number of times the mice entered each arm and the length of stay within 5 minutes, namely the number of entries to the open arms (OE), the number of close arm entries (CE), the time to enter the open arms (OT), and the time to enter the closed arms (CT). The percentage of entries to the open arms to the total number of entries (OE%) and the percentage of time spent in the open arms to the total time in the arms (OT%) were used as indicators to show the anxiolytic effect. During the test, the mouse withdrew one foot from an arm, indicating the completion of the activity. After each test, the maze was wiped to remove feces before the next test.
[0059] Table 1 Elevated plus maze test ( n=10)
[0060]
[0061] As shown in Table 1, both the embodiment group and the comparative example group can significantly increase the percentage of the number of times mice enter the open arms in the elevated plus maze model experiment, and can significantly increase the percentage of the time mice stay in the open arms. The results show that the medicinal and edible compositions of the embodiment group and the comparative example group have good antianxiety effects. Compared with comparative example 1 group, comparative example 2 group and comparative example 3 group, the embodiment group can significantly increase the percentage of the number of times mice enter the open arms in the elevated plus maze model experiment, and can significantly increase the percentage of the time mice stay in the open arms. It can be seen that there is a synergistic relationship between short-stalked Acanthopanax, Kaempferia galanga and chicory. The combination of the three has a significant antianxiety effect and a mild sedative effect. Compared with comparative example 4 group and comparative example 5 group, the embodiment group can increase the percentage of the number of times mice enter the open arms in the elevated plus maze model experiment, and can increase the percentage of the time mice stay in the open arms. It can be seen that the process of the present invention can significantly improve the precipitation rate of each effective ingredient, thereby improving its overall effect.
[0062] Gastric mucosal repair ability experiment
[0063] 90 Wistar rats were selected, half male and half female, weighing 190-230g. They were fasted for 24 hours before the experiment and given water to drink. The abdominal cavity was opened under ether anesthesia, and a glass tube with an inner diameter of 5mm and a length of 30mm was placed vertically on the serosal surface of the gastric body. 0.2mL of glacial acetic acid was added to the lumen. After 1.5 minutes, a cotton swab was used to dip out the glacial acetic acid, and the surgical incision was sutured. After surgery, the rats resumed their normal diet. After 24 hours, the rats were randomly divided into: experimental group 1 (300 mg / kg), experimental group 2 (300 mg / kg), experimental group 3 (300 mg / kg), control group 1 (300 mg / kg), control group 2 (300 mg / kg), control group 3 (300 mg / kg), control group 4 (300 mg / kg), control group 5 (300 mg / kg) and model control group ((physiological saline solution), 10 rats in each group, free access to ordinary food and drinking water, oral gavage once in the morning and evening every day, for 14 consecutive days. Two hours after the last oral gavage, the rat stomach was dissected out, fixed with 10% formaldehyde for 10 minutes, and then the stomach was cut open along the greater curvature of the stomach and flattened on glass. The longest diameter and the shortest diameter of the ulcer site were measured, and the average of the longest diameter and the shortest diameter was used as the ulcer index. The results are shown in Table 2.
[0064] Table 2 Ulcer index of each group
[0065]
[0066] According to the data in Table 2, it can be concluded that the average ulcer index of the model group is 8.94mm, the average ulcer index of the experimental group 1 is 3.6mm, the average ulcer index of the experimental group 2 is 3.45mm, the average ulcer index of the experimental group 3 is 3.44mm, the average ulcer index of the control group 1 is 5.23mm, the average ulcer index of the control group 2 is 5.55mm, the average ulcer index of the control group 3 is 4.9mm, the average ulcer index of the control group 4 is 4.33mm, and the average ulcer index of the control group 5 is 3.9mm. By comparing the above-mentioned average ulcer index, it can be concluded that the experimental groups 1-3 all have good effects of repairing gastric ulcers, and the control groups 1-5 also have certain effects of repairing gastric ulcers, but the effects are not as good as the experimental groups 1-3, and the main reason for the correction is the synergistic enhancement between the components and the differences in the preparation process. It can be seen that the medicine-food homologous composition of the present invention has the effect of repairing mucosal damage.
[0067] When the composition of the present invention is used, it is generally granulated by adding auxiliary materials, and the auxiliary materials can be sweeteners, fillers, etc.
[0068] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
