The following experiment was conducted using the composition for treating oral ulcer prepared in example 1 of the present invention (hereinafter referred to as the composition of the present invention).
2. Effect on rat canker sore model
1. Experimental grouping and modeling
SD male rats 60 are divided into a normal control group, a model control group, a composition group (35.0 mg/kg), a metronidazole group (16.5 mg/kg) and a watermelon frost group (200 mg/kg) according to weight stratification, and each group comprises 10 rats. In each group except the normal control group, rats were i.p. anesthetized with 10% chloral hydrate (3 mL/kg), and injected with 10% acetic acid, 0.1 mL/mouse, under the mucosa of the left buccal cavity of the rat, and the rats developed canker sores after 24 hours. Rats in the normal control group were injected with an equal amount (0.1 mL/mouse) of physiological saline submucosally in the left buccal cavity.
2. Animal drug delivery and index detection
The administration is started on the 2 nd day after the model is made, rats in each group of the composition and the watermelon frost are dripped on the ulcer surface according to the corresponding dosage, metronidazole is ground into powder, the medicine powder is uniformly coated on the ulcer surface, the medicine stays in the oral cavity for 3min after each administration, and normal control groups and model control groups are given with normal saline with the same volume. The administration was continued for 7 days. The maximum transverse diameter (d) of canker sores after model creation and 7d administration was measured with a vernier caliper for each group of rats 1 ) And maximum longitudinal diameter (d) 2 ) The ulcer area (ulcer area = π × d) was calculated 1 ×d 2 X 1/4, pi = 3.14). Scoring by severity of ulcer: (1) red and swollen ulcer mucosa; (2) ulcerated mucous membranes; (3) the surface of the ulcer is covered by a yellow-white pseudo membrane; (4) the center is sunken, and the edge is neat and raised; (5) swollen lips, running water;(6) the food intake is reduced, and the body constitution is lightened. And (3) carrying out quantitative integration on the apparent indexes, and grading: none, mild and significant, and respectively counted for 0, 1 and 2 points. After the last measurement, the rats in each group are sacrificed, tissues at oral ulcer positions are taken off, 9 times of physiological saline is added into partial ulcer tissues for homogenization treatment, the mixture is centrifuged at 4 ℃ and 3000r/min for 10min, supernatant is separated, and the TNF-alpha level in the ulcer tissues is measured according to an ELISA kit method.
3. Statistical processing
Each set of data with
Figure BDA0003625140880000123
Statistical treatment was performed using SPSS 17.0 software, and the test method used was one-way-AVONA (one way-AVONA) and group-by-group comparison LSD.
4. Results of the experiment
4.1 Effect on the area of canker sores in rats
The general morphology of the oral ulcer surface of each group of rats is observed, the result shows that no ulcer is formed in the normal control group, and obvious oral ulcer can appear in other groups after acetic acid injection, which indicates that the preparation of the oral ulcer model is successful. The rat oral ulcer model has certain self-healing property, and the ulcer area is gradually reduced along with the prolonging of time. After the animal model is made, the oral ulcer areas of other groups of rats except the normal control group have no significant difference, and after the animal model is administrated for 7 days, the oral ulcer areas of the rats in the composition group, the metronidazole group and the watermelon frost group are all significantly reduced (P is less than 0.01); compared with the watermelon frost group, the composition group of the invention has obviously smaller oral ulcer area (P is less than 0.05). The results indicate that the composition, metronidazole and watermelon frost all have certain treatment effect on the oral ulcer induced by acetic acid, and the composition is superior to the watermelon frost and has equivalent effect with the metronidazole. The effect on the area of the canker sores in the rats is detailed in table 1.

4.2 canker sore Scoring Condition
The mucosa of the ulcer surface is hollow defect, and is roughly circular, the surface is yellowish white, and the periphery is congested and edematous. Further scoring was performed for ulcer severity at different stages, and the results showed: after 7 days of administration, compared with a model control group, the composition group, the metronidazole group and the watermelon frost group of the invention have obviously reduced oral ulcer scores of rats (P is less than 0.01); compared with the watermelon crystal group, the composition group of the invention has obviously lower oral ulcer score (P is less than 0.05) of rats. The canker sore score results were similar to the canker sore area results. The oral ulcer scores are detailed in table 2.

4.3 Effect on TNF-alpha levels in tissues at the canker sore sites in rats
Compared with a model control group, the TNF-alpha level in the oral ulcer tissue of rats in the composition group, the metronidazole group and the watermelon frost group is obviously reduced (P is less than 0.01). TNF- α level measurements are also similar to the oral ulcer area results, suggesting that the composition of the present invention reduces TNF- α levels in ulcerated tissues, which may be one of the mechanisms of action for treating acetic acid induced oral ulcers. The effect on TNF-. Alpha.levels in tissues at the site of oral ulceration in rats is detailed in Table 3.

Note: compared with the model control group, ** P<0.01。
under the experimental conditions and the designed dosage, the composition has a certain treatment effect on the model of the acetic acid induced oral ulcer of rats, and the composition is superior to watermelon frost. On the other hand, the composition is a traditional Chinese medicine component, and compared with the western medicine metronidazole, the composition has a good effect of treating dental ulcer, and avoids side effects caused by the western medicine.
