Description

A composition for treating inflammation comprising a fermented product of black rice bran and balloon flower by bioconversion}

The present invention relates to a composition for treatment of inflammation comprising a bioconverted black rice bran fermentation and bellflower fermentation.

Atopic dermatitis is an intractable immune disease characterized by pruritus, dryness, and eczema erythematosus. Genetic factors and environmental influences are on the rise as the main pathogenic factors. According to a 2010 survey by the Korea Centers for Disease Control and Prevention, the prevalence of atopic dermatitis, which had itchy rashes in Korean children for the past 12 months, was 20.6% for elementary school students and 12.9% for middle school students, indicating that the incidence of atopic dermatitis tends to be higher with younger age. Compared to the results of the survey, 13.4% and 6.7%, the incidence of disease was significantly increased. Between 1990 and 2010, Africa increased from 9.9% to 20.9%, Europe from 18.9% to 19.6%, and Asia in Japan from 10.1% to 13.6%. It has a high prevalence rate in Western societies and migrant groups due to urbanization, and it is more frequent in Western Europe than Eastern Europe and in developed countries than in developing countries.

Steroids, immunosuppressants, antihistamines, skin moisturizers, skin emollients, etc. are all used to treat atopic dermatitis, but among the drugs used as pharmacological treatments, representative drugs used for mild patients are topical steroids, topical calcineurin inhibitors, and antihistamines. Among them, antihistamines are used to relieve itching, but their efficacy is not so high that they are not very helpful. Accordingly, in the treatment of atopic dermatitis, T cell suppression immunomodulators such as steroids or calcineurin inhibitors are mainly used. Currently, topical steroids used in mild patients and most drugs used in patients with moderate symptoms have serious side effects, so the combination of drug therapy and phototherapy is trying to increase the therapeutic effect and reduce side effects.

As described above, as part of an effort to reduce side effects in the treatment of atopic dermatitis, the need to develop raw materials and products derived from natural products has emerged. Functional materials derived from natural products, which are known to be effective in improving atopic skin, mostly rely on mast cell degranulation inhibitory effects. Antigranulation inhibition in mast cells, which is expected to have the same effect as antihistamines, is expected to be partially effective in relieving symptoms of atopic dermatitis, but antihistamines are only used to relieve itching in atopic dermatitis, and this is also not high in efficacy, so itching. Considering the fact that it is not very helpful in alleviation, the effect of inhibiting degranulation in mast cells is not expected to be significant.

Until now, technologies such as pharmaceutical compositions for the treatment of atopic dermatitis using natural extracts as active ingredients (KR 2018-0138265 and KR 1898262) have been developed, but they are fermented with microorganisms (Basicillus mycelium) or bioconverted through additional enzyme treatment. There is insufficient development of technology for treatment or prevention of inflammation or atopic dermatitis using fermented black rice bran and bellflower fermented as active ingredients.

Accordingly, the present invention relates to a composition for the treatment of inflammation and atopic dermatitis, including fermented with basidiomycete hyphae, or bioconverted through enzyme treatment, and fermented bellflower and fermented bellflower, and its effects.

The present invention was conceived to solve the problems of the prior art as described above, and inflammation and atopic dermatitis including fermented with basidiomycete hyphae or bioconverted fermented black rice bran and bellflower fermented by additional enzyme treatment It relates to a therapeutic composition or a food composition. However, the technical problem to be achieved by the present invention is not limited to the problems mentioned above, and other problems that are not mentioned may be clearly understood by those of ordinary skill in the art from the following description.

Hereinafter, various embodiments described herein are described with reference to the drawings. In the following description, for a thorough understanding of the invention, various specific details, such as specific forms, compositions and processes, etc. are set forth. However, certain embodiments may be practiced without one or more of these specific details, or with other known methods and forms. In other instances, well-known processes and manufacturing techniques have not been described in specific details in order not to unnecessarily obscure the present invention. Reference throughout this specification to “one embodiment” or “embodiment” means that a particular feature, form, composition, or characteristic described in connection with the embodiment is included in one or more embodiments of the present invention. Thus, the context of “in one embodiment” or “embodiment” expressed in various places throughout this specification does not necessarily represent the same embodiment of the invention. Additionally, particular features, shapes, compositions, or properties may be combined in any suitable manner in one or more embodiments.

Unless otherwise defined in the present invention, all scientific and technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

Basidiomycete in the present invention is a fungus that becomes a cell called basidiomycete as a result of sexual reproduction as a subfamily of fungi to create spores. It cannot make nutrients by itself, so it is attached to other organisms and is parasitic, and many are known as mushrooms. Shiitake mushrooms, Pseudomonas mushrooms, Chaga mushrooms, Maitake mushrooms, Wood ear mushrooms, Snowflake mushrooms and skirt mushrooms are representative. Basidis are densely formed on the wrinkled side of mature mushrooms. Most of basidiomycete mushrooms live by-products in the fluids of higher plants, and play an indispensable role in the biological circulation of substances by decomposing cellulose and lignin in particular, but they also form mycorrhizal roots at the roots of trees to live in common. There are also many. There are other types that are considered important as edible bacteria or that need attention as poisonous mushrooms.

In the present invention, mycelium is a vegetative cell of a filamentous fungus (fungus). Functional differentiation, such as nutritional or physiological functions, can also be seen. Formally, the presence or absence of a partition wall is used for classification, and it develops in the germination tube of spores and elongates by apical growth. A group of branched hyphae is called mycelium. Depending on their physiological function, they are divided into basal hyphae that elongate as they enter the surface or inside of a medium or host, and parasitic hyphae that elongate in the air. Parasitic hyphae depend on the transfer of nutrients from the basal hyphae, and some of them differentiate into spore-forming organs. If organic matter is present and environmental conditions such as suitable humidity and temperature are good, various mycelial structures are formed. The diaphragm of the mycelium of associa fungi is simple, but in basidiomyces, it can be seen that it forms a clamp connection. In fungi, it is branched into several branches and tangled like a thread. In mushrooms, it aggregates to form fruiting bodies. Because of the lack of chlorophyll, photosynthesis is not possible and it is attached to host organisms and absorbs nutrients. In the case of basidiomycete, which is a mushroom, a hyphae germinated from a spore has one nucleus, and when it fuses with another hyphae, one cell has two nuclei. A hypha with one nucleus is called a primary hyphae, and a hyphae with two nuclei is called a secondary hyphae. In the present specification, the basidiomycete hyphae can be specifically selected and used from hyphae such as medicinal and edible basidiomycete shiitake mushrooms, phylum mushrooms, chaga mushrooms, Maitake mushrooms, tree ear mushrooms, snowflake mushrooms, and skirt mushrooms, These basidiomycosis hyphae are the Korea Microbial Conservation Center (KCCM), the Korea Research Institute of Bioscience and Biotechnology Life Resource Center (KCTC), the Korea Cell Line Bank (KCLB), the Korea Agricultural Microbial Resource Center (KACC), and the American Standard Strain Culture Recorded Preservation Center (ATCC). The strain can be distributed and used by such institutions.

In the present invention, black rice (Oryza sativa L.) is rice rich in functional ingredients such as anthocyanins and polyphenols compounds, and black rice contains starch, protein, fatty acids, etc. as nutrients. In addition to the anthocyanin and polyphenol compounds described above, fiber, essential minerals for the human body, vitamin B group, vitamin C, niacin, carotene, etc. are contained. It is mixed in small portions and consumed a lot as rice. The medicinal effects of black rice are known for its antioxidant effect, anticancer effect, antiallergic effect, anti-inflammatory effect, and antihyperlipidemia effect due to anthocyanin pigment components, etc., recently processed and developed as a functional food.

In the present specification, the black rice gang refers to a by-product including an outer skin and a little ash layer that is removed during grinding or milling of black rice.

In the present invention, bellflower (Platycodon grandiflorum) is a perennial plant having a thick rootstock. The stem stands upright, grows to a height of 40~80cm, and rarely prunes branches. The leaves are alternately placed on each node, or 2-3 leaves may appear in one place. The leaves are shaped like an elongated egg or oval, and there is no such thing as a petiole. Both ends of the leaf are sharp and have sharp teeth at the edge, and the back of the leaf looks like white powder. Several large bell-like flowers bloom at the end of the stem. The end of the flower is divided into five and has five stamens. The diameter of the flower is about 4cm and the color is dark azure, but some flowers bloom in white. Rhizome is used as a medicinal material, and it is known that Platycodin and Platycodigenin, a kind of saponin contained in the rhizome, have an expectorant and antitussive action.

In the present specification, the bellflower or bellflower powder means composed of all or part of bellflower, and a part of bellflower may be one or more selected from the group consisting of bellflower root, root hair, stem, branch, leaf, bark, and bark, but limited to this no.

In the present invention, biotransformation refers to inducing a structural change of a substance added through a biological method and converting it into a chemically modified form to induce the generation of new components.

In the present invention, fermentation refers to a process in which microorganisms decompose organic substances using their own enzymes. Fermentation is a phenomenon in which organic substances are converted into simple compounds by enzyme action to release free energy, but in general, it refers to a phenomenon in which microorganisms accumulate metabolites through the decomposition process of organic substances. In other words, alcohol fermentation in which yeast decomposes sugar anaerobicly into ethyl alcohol and carbon dioxide, and lactic acid fermentation in which lactic acid bacteria anaerobicly decompose sugar into lactic acid, etc. are typical fermentations, but at present, acetic acid bacteria absorb oxygen in the air. A phenomenon in which alcohol is oxidized to acetic acid by use, and a phenomenon in which molds oxidize glucose to gluconic acid using oxygen in the air are also called acetic acid fermentation, gluconic acid fermentation, and the like, respectively. In addition, these are divided into anaerobic fermentation and aerobic fermentation (oxidative fermentation), and anaerobic fermentation other than those mentioned above includes glycerol fermentation, acetone fermentation, butanol fermentation, 2, 3-butylene glycol fermentation, butyric acid fermentation. , Propionic acid fermentation, methane fermentation, etc., and aerobic fermentation include citric acid fermentation, itaconic acid fermentation, succinic acid fermentation, 2-ketoglutaric acid fermentation, oxalic acid fermentation, fumaric acid fermentation, sorbose fermentation, and the like. In addition, the production of amino acids, vitamins and antibiotics by microorganisms is also called glutamic acid fermentation, riboflavin fermentation, penicillin fermentation, etc., but it is not a very good name. In principle, the name of the fermentation action is called the product, but sometimes the name of the substrate is given by cellulose fermentation or pectin fermentation.

In the present invention, atopic dermatitis refers to a refractory immune disease of chronic inflammatory skin diseases characterized by pruritus, dryness, and eczema erythema. Atopic dermatitis is known to have a combination of genetic and environmental factors, and skin barrier abnormalities and immunological abnormalities are increasing as major pathogens. The terms'atopic' and'allergy' began to be used in the early 20th century and are derived from Greek. 'atopy' is a term meaning out of place by prefixing'a', which is used in the opposite sense to the Greek word'topos', which means place. The word'allergy' is a combination of the Greek word'allos' meaning'different' and the word'ergon' meaning'to work'. When our body reacts abnormally to things that must be taken normally, that is, a word for'modified reaction', it means hypersensitivity. Currently, these two words are used interchangeably.

When foreign substances invade from the outside, our body removes foreign substances in order to protect itself from it and exhibits a reaction to protect the body, which is called an immune response. On the contrary, hypersensitivity reactions work in a harmful direction by destroying tissues by showing an immune response even to things that are not harmful to our body. Hypersensitivity reactions can be divided into four categories: type 1 hypersensitivity reaction, type 2 hypersensitivity reaction, type 3 hypersensitivity reaction, and type 4 hypersensitivity reaction, of which type 1 hypersensitivity reaction is commonly referred to as allergy. In type 1 hypersensitivity reactions, immunoglobulin-E (IgE) is produced against foreign substances (or'allergens') coming from the outside, and when this IgE is combined with the allergen, urticaria, cough, runny nose, sneezing, shortness of breath, etc. Symptoms appear. Type 1 hypersensitivity reactions are also referred to as immediate or IgE-mediated hypersensitivity reactions because hypersensitivity reactions are induced by IgE-mediated after exposure to allergens, and the period until hypersensitivity reactions occur is very short. On the other hand, type 4 hypersensitivity reactions do not immediately show symptoms after exposure to the allergen, but appear gradually, and are also called delayed or cell-mediated hypersensitivity reactions because there is no production of IgE. As it was recently revealed that the basic pathology of allergy is caused by inflammation, cases that appear irrespective of IgE are also included in allergy. After all, allergy can be defined as hypersensitivity reactions that form inflammation in target organs, whether or not related to IgE. That is, allergies include IgE-dependent allergies and IgE-independent allergies.

In the strict sense of the present invention, the term'atopic' refers to a tendency to abnormally generate IgE for foreign substances entering the body from the outside. Therefore, the term'atopic' is not medically identical to the term'allergy'. However, they are actually used interchangeably in the same meaning. In other words, when IgE-mediated hypersensitivity reaction is clinically expressed as a symptom, it is referred to as'atopic disease' and is called'allergic disease'. Traditionally, such diseases include atopic dermatitis, asthma, allergic rhinitis, allergic conjunctivitis, and urticaria. It is being classified. Atopic diseases correspond to IgE-dependent (IgE mediated) allergic diseases, and IgE-independent allergic diseases do not correspond to atopic diseases. In addition, sometimes the term'atopic dermatitis' is too long to be replaced with the word'atopic' for short, but as mentioned above, the definitions of the terms'atopic dermatitis' and'atopy' are clearly different medically, so the exact term is used. I need it.

In the present invention, atopic dermatitis is known as a representative refractory disease that occurs mainly in infancy, and generally refers to atopic eczema accompanied by itching, dry skin, and inflammation. Immunological mechanisms of atopic dermatitis include the enhancement of the Th2 immune response, the imbalance of the Th1 and Th2 immune responses among Th cells, the cytokine dysfunction, and the increase in the activity of Langelhans cells. Recently, it was reported that Th17 immune response also adversely affects atopic dermatitis by Nograles et al.

The common mechanism of IgE-dependent allergic reaction is ① Allergens (external antigens) that cause allergies enter our body, and antigen-specific Th2 cells are activated, ② B cells are activated by cytokines secreted by activated Th2 cells. When IgE antibody-producing B cells are converted to IgE antibody production and secreted, ③ the secreted IgE antibody binds to mast cells and sensitization of mast cells is induced. ④ At this time, the allergen from the outside is obese. Mast cells are activated while binding to IgE bound to the cell surface, secreting various chemical allergy mediators such as histamine, leading to allergic symptoms.

Of these, if the process from atopic dermatitis to the secretion of Th2 cytokines is described in more detail, it can be divided into 7 steps. TSLP is produced from keratinocytes, fibroblasts, mast cells, and dendritic cells of the skin caused by allergens or viruses (step 1), and TSLP activates immature dendritic cells (step 2), and immature dendritic cells activated by TSLP Cells secrete the chemokines IL-8 and eotaxin-2, which not only attract eosinophils and neutrophils, but also secrete thymus and activation-regulated chemokine (TAC) and macrophage-derived chemokine (MDC) to transport Th2 cells to the lesion site. Draw in (step 3). Myeloid dysphagia cells (mDCs) activated by TSLP mature and migrate to the lymph nodes (step 4). Mature dendritic cells activated by TSLP express OX40L on the surface, which promotes antigen-specific naive CD4+ T cells to become inflammatory Th2 cells in lymph nodes. Th2 cells produce IL-4, IL-5, IL-13 and TNF, but not IL-10 (step 5). Since TARC and MDC are generated at the inflammatory site of the lesion, the inflammatory Th2 cells move back to the site of inflammation, which is the lesion site (step 6). In the inflammatory site, Th2 cytokines IL-4, IL-5, IL-13 and TNF are produced by inflammatory Th2 cells, and these cytokines promote IgE production, eosinophil increase and mucus production (step 7) .

When atopic dermatitis patient scratches the skin due to itching or is exposed to allergens, TSLP is secreted from the keratinocytes of the skin, and this secreted TSLP affects Langerhans cells and as a result secretes Th2 cytokines from activated inflammatory Th2 cells. It is known to make.

From an immunological point of view, atopic dermatitis is a disease that occurs when the balance of specific immune responses called Th1/Th2 is broken along with the enhancement of the Th2 immune response. At this time, it is TSLP (Thymic stromal lymphopoietin) that plays an important role. TSLP is secreted from skin keratinocytes, etc. in the stage of atopic dermatitis development, causing Th2 immune response by differentiating naive Th0 cells into Th2 cells. When TSLP is secreted excessively, the Th2 immune response increases and the Th1/Th2 balance collapses, leading to atopic dermatitis progression or worsening. From an immunological point of view, treatment of atopic dermatitis needs to restore the balance of Th1/Th2 immune responses by inhibiting the production of TSLP and reducing the Th2 immune response.

TSLP is mainly made from keratinocytes of the skin and epithelial cells of the airways and nasal mucosa, and stimulates immature myeloid dendritic cells (mDC), which is a heterodimeric TSLP receptor (receptor) in order for the immature dendritic cells to become mature dendritic cells. Express. TSLP-activated dendritic cells differentiate naive CD4+ T cells into Th2 phenotype, and promote the proliferation of Th2 memory cells by expressing costimulatory molecule OX40 ligand together with Th2 chemotactic cytokines TARC (CCL17) and MDC (CCL22). In addition, TSLP inhibits the IL-12 p40 receptor expressed in dendritic cells, suppresses the Th1 immune response, and further promotes the Th2 immune response. TSLP activates the transcription of the IL-4 gene in Th2 cells, promotes the production of IL-13 in mast cells, and increases the response of basophils to infiltrate eosinophils, thereby exacerbating the allergic inflammatory response. Therefore, TSLP plays a key role in the initiation of atopic dermatitis. TSLP is expressed in epithelial cells of atopic dermatitis patients. In addition, TSLP overexpression in skin keratinocytes in mice amplifies inflammatory responses to sensitized inhaled antigens.

Atopic dermatitis is the most characteristic symptom of severe itching. Relieving it is an effective way to improve the quality of life and prevent the worsening of skin lesions. Briefly summarizing the mechanism by which the itching of atopic dermatitis is amplified, when external irritation penetrates the damaged skin barrier and reaches the skin, an allergic inflammatory reaction is triggered, and the resulting itching is'itching → scratching → inflammation → (again) → itching. → scratching → inflammation →… … It is amplified beyond control through the vicious cycle of'.

The mechanism from skin inflammation to itching in atopic dermatitis has not yet been fully elucidated, but interleukin-31 (IL-31) is considered to be the main factor closely related to itching among several mediators that are produced by inflammatory reactions and cause itching. . IL-31 is mainly produced by Th2 cells, and sends a signal through binding to the IL-31 receptor expressed in the sensory nerve and skin keratinocytes. At this time, IL-31 is the sensory nerve. It binds to IL-31 receptor to induce itching, and increases expression of TARC(CCL17), MDC(CCL22), S100A7, β-defensin2 by binding to IL-31 receptor of keratinocytes, and expression of filaggrin, corneodesmosin By suppressing the skin lesions appearing in atopic dermatitis worsen.

It is known that S. aureus bacteria are proliferating on the skin of many atopic dermatitis patients (about 90%) including severe atopic dermatitis patients. Recently, it is known that Th2 cytokines create favorable conditions for proliferation of S. aureus, whereas S. aureus is known to promote the secretion of Th2 cytokines.

Th2 cytokine is known to promote the death of keratinocytes by S. aureus alphatoxin, and deltatoxin is known to promote IgE production and increase the effect of Th2 cytokine. In addition, Staphylococcal enterotoxin B, known as superantigen, is known to increase degranulation in mast cells and promote the secretion of IgE antibodies and aggravate lesions by promoting the secretion of Th2 cytokines. In addition, it is known that Peptidoglycan of S. aureus can induce Th2 immune response in mice. It is known that Peptidoglycan is a ligand of TLR2. It has also been reported that TSLP production in keratinocytes is induced through the pathways of TLR2 and TLR6 by the membrane of S. aureus and diacylated lipopeptide.

In conclusion, Th2 cytokine helps the proliferation of S. aureus, whereas S. aureus can induce TSLP and Th2 cytokine, so S. aureus may exacerbate atopic dermatitis.

To overcome this, the clinical guidelines recommend the use of antibiotics in the treatment of secondary infections. In particular, the materials presented in this patent are TLR4 agonist, and Th1 adjuvant of LPS competitive inhibitor. As it can be used as a Class II antibiotic adjuvant, it is expected that additional effects on atopic dermatitis can be expected.

The guidelines for treatment according to the Korean Atopic Dermatitis Treatment Guidelines (2015) are as follows.

Atopic dermatitis is treated with mild patients and moderate/severe patients. This is because in the case of mild patients, even if the symptoms worsen, it does not progress to more than moderate symptoms, but in the case of moderate patients, it progresses to severe.

Regardless of symptoms, atopic dermatitis patients should use moisturizers as basic treatment, avoid exacerbation factors, and receive patient education. For skin lesions of patients with mild atopic dermatitis, topical anti-inflammatory treatments such as topical steroids and local calcineurin inhibitors should be used as active treatments to eliminate the lesion, and antihistamines are used if itching complains. For reference, unlike general inflammation, general nonsteroidal anti-inflammatory drugs are not used as a basic treatment.

For patients with moderate or higher severity, systemic treatments must be used as active treatment, including treatments for mild patients. In addition, in the case of moderate to severe atopic dermatitis, in systemic treatment, “cyclosporine, short-term systemic steroids, other systemic immunomodulators (AXA, MMF, MTX, IFN-γ, Alitretinoin), phototherapy, antigen-specific immune therapy, biological agents. In addition, when moderate to severe dermatitis worsens, poultice therapy and antibiotics may be used.

After symptoms disappear, topical calcineurin inhibitors or topical steroids are applied 2-3 times a week for maintenance, and proactive treatment is recommended to prevent recurrence. Other than that, although the effect has not yet been clearly demonstrated, evening primrose oil, probiotics and prebiotics, and vitamin D can be used as an adjunct treatment.

Most of the symptoms of atopic dermatitis appear on the skin, so it can be misunderstood as a simple skin disease.However, atopic dermatitis is caused by a continuous recurrence of underlying inflammation due to not only abnormal skin barrier but also abnormally activated immune system function. Although they can be classified, since they are different from general inflammation, nonsteroidal anti-inflammatory drugs commonly used in inflammatory diseases are rarely used as therapeutic agents.

Therefore, in the treatment of atopic dermatitis disease, treatment of Th2 immune hypersensitivity rather than inflammation shows superior long-term effects. Therefore, the method for treating atopic dermatitis, strictly speaking, can be said to change the direction of the immune response such as suppressing the Th2 immune hypersensitivity reaction rather than suppressing inflammation.

In the present invention, atopic dermatitis is one of chronic inflammatory skin diseases with itching as the main symptom, and it mainly begins in infancy or childhood, and itching, skin dryness, skin lesions, lichenification, atopic eczema, erythema and inflammation, etc. Accompany. Symptoms derived from atopic dermatitis are characterized by chronic recurrence and are accompanied by persistent mental and physical pain to the patient. As treatments for atopic dermatitis, steroids, calcineurin inhibitors, antihistamines, immunomodulators, interferon-gamma, and the like are currently being used. Of these, the steroids are most widely used as treatments for atopic dermatitis due to their rapid improvement. If you reduce or quit, the symptoms rapidly worsen, and there is a disadvantage in that there is a risk of various serious side effects including Cushing's syndrome. Due to the shortcomings of such steroids, calcineurin inhibitors, immunomodulators, interferon-gamma, etc. are used in place of steroids, but the immunomodulators are at risk of side effects such as burning skin, high blood pressure, and renal dysfunction. In addition, the antihistamine is accompanied by symptoms such as drowsiness and dry mouth, and when the interferon-gamma is injected, the therapeutic effect appears several weeks later, and an immediate symptom relief effect cannot be expected. Atopic dermatitis symptom relief using natural substances extracted from nature (especially plants) is capable of effectively preventing, alleviating or treating atopic dermatitis symptoms without side effects even if used for a long period of time by supplementing the shortcomings of these conventional chemical compositions. Sexual skin disease treatments are in the spotlight.

In addition, in the case of atopic dermatitis, in addition to steroidal anti-inflammatory drugs, immunosuppressants, and antihistamines, secondary infection treatments are used as needed, but immune hypersensitivity itself is not improved and side effects are serious, making it difficult to use repeatedly for a long time. Therefore, in the reality that there is no suitable oral systemic treatment that can suppress the immune hypersensitivity reaction to Th2 that occurs in the body in mild treatment and maintenance treatment, which are mainly used for external skin, the treatment effect is increased and side effects are reduced by combining drug treatment and phototherapy. It is trying to reduce it, and also eating health functional foods such as probiotics (lactic acid bacteria), which are known to be helpful in improving atopic dermatitis, are being made.

Taken together, the difference between almost all products that have a mechanism to suppress the immune response up to now is that steroids suppress immunity most widely, whereas recent products are characterized by suppressing only a narrow range of immunity. However, it can be said that there is no product that solves the Th1/Th2 imbalance along with the enhanced Th2 immune response enough to change the disease progression.

The present invention contains a Th1 adjuvant capable of solving the Th1/Th2 imbalance along with such an enhanced Th2 immune response, and fermented with basidiomycete hyphae or bioconverted fermented black rice bran and bellflower by further enzymatic treatment. Inflammation, including fermented products, and atopic dermatitis treatment composition and its effect.

In the present invention, IgE is an antibody protein also called immunoglobulin E. It is often referred to as "allergic antibodies" because it plays an important role in allergic reactions. When you are allergic to a specific substance (allergen), the immune system erroneously judges that generally harmless substances are harmful to the body. When exposed to these specific substances, the immune system begins to produce IgE to protect our body. The IgE antibody remains in the body and causes an allergic reaction the next time it comes into contact with the allergen. As a result, in people with allergies, blood IgE levels increase, and IgE exhibits specificity for each allergen.

As a result of confirming the amount of IL-4, IL-5, and IL-13 in the lesion tissue by the RT-PCR method, it was confirmed that the expression level increased by more than 5 times compared to normal mice due to the induction of atopic dermatitis. In the case of mice administered with black rice bran fermentation and bellflower fermentation, the expression levels of IL-4, IL-5 and IL-13 were all decreased. The black rice bran and bellflower raw material showed very weak, slight inhibitory effect, but the black rice bran and bellflower fermented product showed significantly improved inhibitory activity compared to the original. In particular, all mixed powders of fermented black rice bran and bellflower fermented according to the mixing ratio showed higher inhibitory activity, showing a synergistic effect by mixing, and fermented black rice bran and bellflower fermented at 3:1. In the case of mice to which the mixed powder was administered, the expression levels of IL-4, IL-5, and IL-13 decreased by 48.8%, 49.1%, and 49.7%, respectively, showing the most excellent inhibitory activity.

The ear thickness of mice induced atopic dermatitis due to treatment with DNCB and mite extract was measured to confirm the effect of the developed material on ear swelling according to the mixing ratio of fermented black rice bran and fermented bellflower. As a result of measuring the ear thickness, as atopic dermatitis was induced, the ear thickness increased 2.01 times, and in black rice bran and bellflower raw materials, 39.8% and 25.2% were decreased, respectively, showing a slight inhibitory effect. In bellflower fermented products, it was confirmed that 75.7% and 63.7% were decreased, respectively, showing significantly improved inhibitory activity compared to the original product. Single administration of fermented black rice bran showed higher inhibitory activity than single administration of fermented bellflower, and the inhibitory activity increased when combined administration of fermented black rice bran and fermented bellflower compared to the single administration of fermented black rice bran and fermented bellflower. It was confirmed that, as the dose of black rice bran fermentation increased, the inhibitory activity was evaluated to increase. In particular, the combined administration of 30 mg/kg of black rice bran fermentation and 10 mg/kg of bellflower fermentation showed an inhibitory effect of 84.5%, showing much superior inhibitory activity compared to the single administration of black rice bran fermented product and bellflower fermented product. As a result, fermented bellflower seems to have a synergistic effect in improving the activity of fermented black rice bran to inhibit atopic dermatitis. The results are shown in FIG. 5.

Results 4. Serum IgE measurement in atopic dermatitis induced by DNCB and tick extract

By measuring the amount of IgE in the serum of atopic dermatitis-induced mice, the effect of inhibiting IgE production of the developed material was confirmed according to the mixing ratio of fermented black rice bran and fermented bellflower. After sacrifice of the mouse, blood was collected from the heart, the serum was isolated, and the amount of IgE in the serum was measured by ELISA. As a result of the induction of atopic dermatitis, the amount of IgE produced in the serum increased by 7.15 times. It decreased by 31% and 20.8%, confirming a slight inhibitory effect. On the other hand, in black rice bran fermented product and bellflower fermented product, the amount of IgE produced was reduced by 69.2% and 60%, respectively, showing significantly improved inhibitory activity compared to the original product. Like the thickness of the ear, the single administration of black rice bran fermentation showed higher inhibitory activity than the single administration of bellflower fermentation. Also, compared to the single administration of black rice bran fermented product and bellflower fermented product, it is inhibited when combined administration of black rice bran fermented product and bellflower fermented product. It was confirmed that the activity increased, and it was evaluated that the inhibitory activity increased as the dose of black rice bran fermentation increased. In mice treated with 30 mg/kg of black rice bran fermentation and 10 mg/kg of bellflower fermentation, 82.4% of IgE production was inhibited, showing much superior inhibitory activity compared to the single administration of black rice bran fermentation and bellflower fermentation. In view of the presence, it seems that fermented bellflowers exhibit a synergistic effect in improving the activity of inhibiting atopic dermatitis of fermented black rice bran. The results are shown in FIG. 6.

Results 5. Measurement of TLSP in lesion tissue in atopic dermatitis induced by DNCB and tick extract

By measuring the amount of TSLP in the ear tissue of atopic dermatitis-induced mice, the effect of inhibiting TSLP expression according to the mixing ratio of black rice bran fermentation and bellflower fermentation was confirmed. As a result of measuring the amount of TSLP in the ear tissue after mouse sacrifice by the ELISA method, the expression level of TSLP in the ear tissue increased by 6.3 times as atopic dermatitis was induced, and 31.9% and 22.5% in the original black rice bran and bellflower, respectively. It decreased, and a slight inhibitory effect was confirmed. On the other hand, it was confirmed that the fermented black rice bran and bellflower fermented products decreased by 69.3% and 58.9%, respectively, showing significantly improved inhibitory activity compared to the original product. The single administration of fermented black rice bran showed higher inhibitory activity than the single administration of fermented bellflower. As in the previous results, the inhibitory activity of the composite material was superior to that of the single material. It was confirmed that the higher the inhibitory activity, the higher the inhibitory activity. In particular, 85.9% of TSLP production was inhibited in mice administered with 30 mg/kg of black rice bran fermented product and 10 mg/kg of bellflower fermented product, which is much superior to the single administration of black rice bran fermented product and bellflower fermented product. It seems that fermented bellflowers have a synergistic effect in improving the activity of inhibiting atopic dermatitis of fermented black rice bran. In atopic dermatitis, TSLP produced by keratinocytes has been reported to trigger a chronic Th2 inflammatory response by activating dendritic cells. Therefore, it is expected that administration of fermented black rice bran and fermented bellflower can alleviate atopic dermatitis by controlling chronic inflammatory reactions through inhibition of TSLP production. The results are shown in FIG. 7.

Results 6. Measurement of IL-31 in the lesion tissue in atopic dermatitis induced by DNCB and tick extract

By measuring the amount of IL-31 in the ear tissue of atopic dermatitis-induced mice, the effect of inhibiting IL-31 expression according to the mixing ratio of black rice bran fermentation and bellflower fermentation was confirmed. As a result of measuring the amount of IL-31 in the ear tissue after mouse sacrifice by the ELISA method, the expression level of IL-31 protein in the ear tissue increased by 5.97 times as atopic dermatitis was induced. 27.2% and 16% decreased, showing a slight inhibitory effect, and 65.5% and 52.2% of black rice bran fermented product and bellflower fermented product decreased, respectively, showing significantly improved inhibitory activity compared to the original product. The single administration of black rice bran fermentation showed higher inhibitory activity than the single administration of bellflower fermentation, and the inhibitory activity of the composite material was also superior to that of the single material. It was confirmed that the activity increases with increasing. In particular, the expression level of IL-31 was inhibited by 73.7% in mice administered with 30 mg/kg of black rice bran fermented product and 10 mg/kg of bellflower fermented product, compared to single administration of black rice bran fermented product and bellflower fermented product. Considering that it exhibits excellent inhibitory activity, fermented bellflower seems to exhibit a synergistic effect in improving the inhibitory activity of atopic dermatitis of fermented black rice bran. IL-31 is known as a cytokine that induces itching in atopic dermatitis, and administration of black rice bran fermentation and bellflower fermentation can effectively alleviate itching caused by atopic dermatitis. The results are shown in FIG. 8.
