A Chinese medicinal composition for regulating oral flora and preparation method of active extract thereof
Technical Field
The invention belongs to the technical field of traditional Chinese medicine oral care, and particularly relates to a traditional Chinese medicine composition for adjusting oral flora and preparation of an active extract thereof.
Background
Many people feel that the mouth odor exists in the self or the other party, so that the two parties generate certain gap and distance in communication, great influence is generated on life and work, and the normal social interaction is obstructed. The microbes planted in the oral cavity coexist, compete and antagonize at different positions, are closely related to the health and diseases of the oral cavity of a host, in the oral cavity, the oral cavity can keep a healthy state only by keeping dynamic ecological balance among the microbes and between the microbes and the oral cavity of the host, if external microbes exist in the oral cavity or the proportion of individual microbes or a plurality of microbes inherent in the oral cavity microbial ecology is obviously increased to become dominant bacteria of the planted positions, the oral cavity micro-ecological system balance is broken, and dysbacteriosis can occur to cause oral diseases. The distribution and the total number of oral flora of patients with oral odor are obviously different from those of normal people, the number of pathogenic bacteria related to oral diseases is obviously higher than that of the normal people, pathogenic dominant bacteria decompose substances in the oral cavity to generate volatile sulfides and fatty acid, the volatile sulfides in abnormal breath are obviously increased, and the oral odor is generated.
Aiming at oral peculiar smell caused by oral microecological imbalance, the current solution is to solve dysbacteriosis. The oral cavity disease is treated, the generation of harmful gas in the oral cavity is eliminated, the dietary structure is adjusted, the hygienic habit is improved, the disease is treated by antibiotics, and the like, but measures such as using substances such as chewing gum and the like to enhance the oral hygiene and brushing teeth everyday, using oral cavity gargle and the like also have certain effects. However, antibiotics are limited in use and many types of mouthwashes are often single-acting or poorly effective. The existing oral care products containing traditional Chinese medicine components have the function of masking the peculiar smell of the oral cavity, do not have the function of adjusting oral microorganisms, or have a certain killing function on oral harmful bacteria, but cannot provide the function of refreshing the oral cavity.
Oral ulcer is a common oral disease, and is easy to be in a state of tension and high mental stress frequently along with the fast pace of life and study; or oral ulcer, which is a civilized disease, frequently occurs due to bad living habits, and is common to cold. It usually grows on lips, tongue or other parts of oral cavity, and can recur frequently, with good time and bad time, and is not classified into men and women, old and young. The flora in the oral cavity is symbiotic with the host, generally, the oral cavity is in a balanced state, if the balanced oral flora is damaged, oral diseases including oral ulcer can occur, and the change of the contents of streptococcus, veillonella flora and neisseria flora in the oral ulcer can directly influence the oral micro-ecological balance.

Each group of rats was anesthetized with ether and fixed supine on a rat plate. A glass tube with the diameter of 4 mm is taken, a small cotton ball is placed at one end of the glass tube to be flush with the tube opening, the cotton ball end of the glass tube is soaked in phenol solution with the mass fraction of 900 g/L to enable the liquid medicine to soak the cotton ball, and the cotton ball is placed on the buccal mucosa of one side of a rat to be burnt for about 60 s. The glass tube is removed, white damage with the diameter of 4-6 mm can be seen in the area, and the lips of the rat mouth can be seen to be moist, the mouth can flow into water, the buccal mucosa is red and swollen by naked eyes the next day, namely the oral ulcer modeling is successful.
In the large-dose group of the combination, 1250 mu L of the combination is given per 100g of body mass (equivalent to 15 times of the daily dosage of clinical people), and the combination is averagely dropped into the ulcer part of the buccal mucosa of a rat for 5 times at intervals of 2 hours.
In the small-dose group of the combination, 415 mu L of the combination is given per 100g of body mass (which is 5 times of the daily dosage of clinical people), and the combination is averagely dropped into the ulcer part of the buccal mucosa of a rat for 2 times at intervals of 4 hours.
Ice boron tablet group: the Bingpeng buccal tablet powder is 1.5 mg/g, and is placed on the ulcer of the buccal mucosa of a rat at an interval of 2h in 5 times on average.
The model control group was not administered.
For the large dose group, the small dose group and the Bingpeng tablet group, after each administration, fasting and water prohibition are performed for 30 min, and the continuous administration is performed for 6 d. The healing of the canker sores in the rats was observed before daily dosing, and the size of the diameter of the canker sore surface (in mm) and the time and amount of healing of the canker sores in the rats were recorded 6 days after dosing. The healing standard is that the ulcer with the diameter less than 1mm is healed, and the ulcer with the diameter more than or equal to 1mm is not healed. The results are shown in Table 2. Compared with a model control group, when the combination is continuously administrated for 6 d, the diameter of the oral ulcer surface of rats in the large and small dose groups of the combination is reduced, the number of the rats with the healed oral ulcer is increased, the difference has statistical significance (P is less than 0.01 or P is less than 0.05), and the results are shown in a table 2:
TABLE 2 comparison of the diameter of the oral ulcer surface of each group of rats x + -s
※Compared with the model group, the difference is significant (P is less than 0.05),﹟the difference is significant compared with a positive control group (P is less than 0.05)
From the experimental results of table 2, it can be seen that: after the experimental rat oral ulcer model is successfully manufactured and the medicine is applied for treatment, the ulcer area is reduced by the traditional Chinese medicine combination active extract A and the positive medicine group, and the difference is obvious (P is less than 0.05).
