Description

Technical Field

[0001] The present invention relates to the fields of probiotics, health food and microecological preparations, and in particular to a Pentabiotics bacteria capable of regulating and improving diarrhea, constipation and irritable bowel syndrome and an application thereof. Background Art

[0002] The intestinal microbiota plays a vital role in maintaining health. They are involved in multiple physiological processes from nutrient absorption to immune regulation. However, this microbial balance may be disrupted by a variety of factors such as diet, lifestyle, antibiotic use, and disease, leading to intestinal flora imbalance. This imbalance is associated with gastrointestinal diseases such as diarrhea, constipation, and irritable bowel syndrome (IBS).

[0003] Diarrhea and constipation are common symptoms of intestinal dysfunction, and IBS is a common functional bowel disease characterized by chronic abdominal pain, discomfort, bloating and changes in bowel habits. The abdominal pain is often relieved after defecation, which can significantly reduce the patient's quality of life and work efficiency. The exact cause of IBS is not yet fully understood, and there is still a lack of very effective treatment for IBS, but studies have shown that changes in intestinal flora play an important role in its development. In the intestinal flora of IBS patients, the ratio of Firmicutes to Bacteroidetes increases, the diversity of the flora decreases, and the number of mucosa-associated flora increases and the composition changes. IBS can be divided into four subtypes: constipation, diarrhea, mixed, and amorphous. The diarrhea type is the most common subtype. In the treatment of IBS, the effect of probiotics has been supported by some clinical studies. Probiotics can be used to prepare related foods or health foods, which have better safety than drugs.

[0004] Probiotics colonize in the host's intestines or reproductive system, can improve intestinal health, balance the flora, and are called microecological regulators. Their probiotic effects are mainly achieved by improving the balance of the host flora and activating the activity of the host's endogenous microbial flora or immune system, which has a beneficial effect on the body. As beneficial active microorganisms, probiotics have been widely studied for restoring the balance of intestinal flora. They play a role by enhancing the barrier function of the intestinal mucosa, preventing the adhesion and colonization of pathogens, and enhancing immune response. Probiotics have a variety of physiological functions, mainly including helping the absorption of nutrients, regulating intestinal flora, improving diarrhea, relieving allergic reaction symptoms, improving the body's immunity, and reducing the risk of infection with inflammatory bowel disease, irritable bowel syndrome and other diseases. However, there are few studies on the use of multiple strains of probiotics to synergistically enhance the effect of compound compositions in improving diarrhea, constipation, and irritable bowel syndrome.

Experimental Example 1 Investigation of the effect of the probiotics of the present invention on constipation model mice

[0039] The probiotics described in the present invention are provided by Jianma Pharmaceutical (Guangdong) Co., Ltd., and other raw materials and reagents can be obtained commercially. The method for preparing the bacterial suspension involved in the experiment is as follows: the probiotics are inoculated into the MRS liquid culture medium, cultured at 34-39°C for 18h-24h for activation, and activated twice in succession to obtain an activated liquid; the activated liquid is inoculated into the MRS liquid culture medium at an inoculation rate of 2%-4% (v / v), and cultured at 34-39°C for 18h-24h to obtain a bacterial liquid; the bacterial liquid is centrifuged, the bacteria are resuspended with PBS, and the required concentration of the bacterial liquid is adjusted according to the experiment.

[0040] 120 SPF male Kunming mice weighing 18-23g were selected. The mice were adaptively cultured for one week and the animals were free to eat and drink. The experimental animals were randomly divided into 10 groups, with 12 mice in each group, namely blank group, model control group, Example 1-5 group, and comparative example 1-3 group. Except for the blank group, each group was gavaged with loperamide hydrochloride every day, once in the morning and once in the evening, for 7 consecutive days to induce a functional constipation model in mice, and the blank group was gavaged with the same amount of normal saline. Then, 0.2mL of bacterial solution was gavaged every day from the example and the comparative example, and the concentration of the bacterial solution was 1.0×10 9 CFU / mL. The blank group and the model control group were gavaged with an equal volume of saline. All mice were free to drink water and eat, and the feeding was continued for 14 days. After 14 days, the mice in each group were fasted for 12 hours but not water, and then each group was gavaged for the last time. One hour after the gavage, an equal amount of activated carbon suspension was given. After 20 minutes, the mice were killed by dislocation, the abdomen was opened to obtain the small intestine, the carbon powder advancement distance and the total length of the small intestine were measured, and the advancement rate (%) was calculated. The test results are shown in Table 1.

[0041] Propulsion rate (%) = activated carbon propulsion length (cm) / total length of small intestine (cm) × 100% Table 1 Effects on small intestinal motility of constipated mice (MEAN±SD, n=12)

[0042] As can be seen from Table 1, the small intestinal propulsion rate of the model control group is significantly lower than that of the blank group, indicating that the constipation model is successful. At the same time, the small intestinal propulsion rate of the composite pentabiotic group (example group) prepared by the present invention is significantly higher than that of the comparative group and the model control group, indicating that it can effectively promote gastrointestinal motility. The pentabiotic group of the specific bacteria species works together to exert synergistic synergy, accelerates the propulsion speed of activated carbon in the small intestine, and thus can improve and treat constipation. Experimental Example 2 Effect of the probiotics of the present invention on diarrhea-type IBS in mice induced by senna leaves

[0043] 120 SPF male Kunming mice weighing 18-23g were selected. The mice were adaptively cultured for one week and the animals were free to eat and drink. The experimental animals were randomly divided into 10 groups, 12 in each group, namely, blank group, model control group, Example 1-5 group, and Comparative Example 1-3 group. Each group was pre-administered with liquid for 6 days, and the Example and Comparative Example were gavaged with 0.2mL of the corresponding bacterial solution every day, and the concentration of the bacterial solution was 1.0×10 9 CFU / mL (see the above test example for the preparation of bacterial solution), the blank group and the model control group were gavaged with the same amount of normal saline once a day. Fasting for 12 hours before the last administration of solution, 1 hour after the administration, the mice except the blank group were gavaged with senna leaf decoction at a dose of 1g crude drug / kg to establish a diarrhea-type irritable bowel syndrome model, and the blank group was given the same volume of deionized water. The diarrhea of ​​mice was counted from 3 hours after gavage, and the number of diarrhea times in the two time periods of 3 hours and 6 hours was calculated to compare the statistical differences between the groups. Soft stools, watery stools, mucous stools, etc. are called diarrhea stools. The test results are shown in Table 2.

[0044] Table 2 Comparison of antidiarrheal effects on diarrhea-type IBS in mice induced by senna leaves (MEAN±SD, n=12)

[0045] From the experimental results in Table 2, it can be seen that intragastric administration of senna leaf decoction can effectively prepare a mouse diarrhea model. Compared with the model group, the number of diarrhea episodes in each group given different test substances decreased. Under the same probiotic dosage, the composite probiotic combination containing five species can better improve the incidence of diarrhea, while the effect of using them alone or in combination with some of the probiotics did not significantly improve the related diarrhea frequency. It can be seen that the pentabiotics described in the present application can better promote the proliferation and colonization of probiotics in the body, improve the intestinal environment, have a significant inhibitory effect on diarrhea-type IBS, and can effectively relieve diarrhea symptoms.
