Description

Composition for preventing or treating inflammatory pain comprising cinnamon extract as an active ingredient {COMPOSITION FOR PREVENTION OR TREATMENT OF DENTAL DISEASE COMPRISING AN EXTRACT OF CINNAMON}

The present invention relates to a composition for preventing or treating inflammatory pain comprising cinnamon extract as an active ingredient, effectively alleviating pain and secreting saliva in the oral cavity to effectively acute inflammatory pain and facial pain caused by oral diseases It relates to a composition that can be prevented or treated.

The inflammatory process is a series of complex biochemical and cellular events that are activated in response to the presence or damage of foreign substances, causing swelling and pain. The inflammatory process is a defense mechanism against conventional pathogenic factors, but can cause pain even in the absence of stimulation of toxic substances. Local inflammatory reactions release pro-inflammatory cytokinins and upregulate cyclooxygenase-2 to synthesize prostaglandins. This makes primary primary neurons sensitive, and activates neuroimmunity by sensitizing nearby nerve cells. Thus, a thermal or mechanical hypersensitivity occurs. When the inflammatory reaction as described above occurs, pain is involved. These pains are nociceptive pain, which is a kind of warning sensation caused by harmful stimuli that can damage or potentially damage tissue, and damaged tissue and surrounding tissue. Inflammatory inflammatory pains caused by inflammatory mediators such as IL-1β (interleukin 1) that are activated and secreted from the inflammatory receptors, and neuropathy that persists even in non-toxic stimuli due to damage to the peripheral and central nerves It can be distinguished as pain (neuropathic pain).

In particular, the inflammatory pain includes cases that develop into neuropathic pain, such as trigeminal neuralgia and migraine, as well as acute facial pain due to damage to the teeth, alveolar bones, oral soft tissue and temporomandibular joint.

Inflammatory pain prevents further damage by limiting the movement of the pain area and disappears after a certain period of time, but it seems to be important to control inflammatory pain because it may develop into neuropathic pain as it progresses in the direction of harm to ‹š.

The acute facial pain may occur during dental treatment, scaling, or other dental hygiene procedures, and sometimes refers to regular or irregular sudden pain without a specific cause.

The acute facial pain may be specifically divided into afferent blockage pain syndrome, trigeminal neuralgia, mouthburn syndrome, and tension headache.

The centripetal blockage pain syndrome The centripetal blockage pain syndrome refers to a condition in which sensitization occurs when there is damage or inflammation of the sensory nerve, and pain persists even when there is no cause of external pain. In this case, sudden pain may occur due to dental treatment, scaling, or other mild stimulation, and small pain may be felt greatly. Sometimes, in addition to pain, a strange sensation may be felt. Most of the cases of burning, tingling, tingling, or dull pain in the adjacent area after treatment of a tooth or removal of a tooth from a dentist or after treatment of a gum are often associated with afferent pain syndrome. In addition, the acute facial pain associated with the afferent pain syndrome is not treated well with general pain relievers, and many antidepressants and anticonvulsants are used. Recently, capsaicin cream or gabapentin may be used.

In addition, the trigeminal neuralgia causes shocking pains such as sudden electricity in the face or mouth during everyday life, and does not move. After that moment, the pain immediately disappears, but if you touch any part of the face or mouth, it becomes electricity again. It is characterized by recurring pain that seems to cause pain. Most of the patients appear in middle-aged or older, and the pain appears only on either side of the left or right side of the face or chin. It does not appear on both sides. These trigeminal neuralgia rarely have a therapeutic effect as a general pain reliever, and drugs such as carbamazepine, bacrofen, and amitriptyline should be used alone or in combination. The drug must be used for a long time, so you need to be aware of side effects and undergo regular blood tests. If medication is ineffective, surgery may be considered.

In addition, the burning sensation syndrome refers to feeling of pain in the mucous region of the tongue or mouth without any specific cause, and is mainly seen in postmenopausal women. Patients with burning sensation syndrome often complain of burning or tingling or soreness in the 2/3 area of the front of the tongue, anterior of the palate, and lips, but sometimes the symptoms include dry mouth and taste disorders. The exact cause of the burning sensation syndrome has not been identified, and it is assumed that only hormonal changes, psychological factors, and degenerative changes in the taste nerve are involved. In general, it is possible to relieve symptoms by administering amitriptyline and clonazepam or applying capsaicin cream, but it is not easy to cure. In the case of oral candidiasis, antifungal agents such as nistatin or ketoconazole should be used, and if dry mouth feels, pilocarpine or artificial saliva is prescribed.

Furthermore, the tension headache is the highest incidence among headaches and appears as a feeling of head tightening, heavy or throbbing. It usually feels pain on both sides of the head and is worse in the afternoon than in the morning. The intensity of the pain is not constant, but it does not appear extreme. Stress or muscle tension are known to be the main causes of tension headaches, but other causes are also involved. Drug therapy is mainly used for the treatment of such tension headaches, but a better therapeutic effect can be obtained when both behavioral therapy and physical therapy are performed. Recently, Botox injection is recommended as a treatment for tension headaches.

Therefore, the acute facial pain in the present invention includes acute facial pain caused by afferent blockage pain syndrome, trigeminal neuralgia, oral burning syndrome, and tension headache, and is defined as including sudden and temporary accompanying oral facial pain symptoms. .

In addition to these inflammatory pains, as the society ages, patients with degenerative arthritis and low back pain are on the increase every year, but existing opioids such as morphine are restricted due to drug action to the general public, so the demand for pain relievers is much higher in the future. It is always expected. In addition, the development of painkillers for pain that does not respond to existing painkillers is greatly demanded, and the general patient cannot use them conveniently due to the narcotic and serious side effects of the existing opioid-like drugs, which are known to have relatively high analgesic effects. Therefore, it is necessary to develop a natural resource that has no side effects and has an analgesic suppression effect.

On the other hand, in oral health, saliva plays a very important role. Specifically, it is known to prevent dry mouth, protect the oral cavity from environmental stress, and inhibit oral pathogen adhesion to teeth by combining with oral lubrication and pathogens. Therefore, those who have less production of saliva, which is responsible for the health of the oral cavity, are relatively likely to be exposed to oral disease.

Saliva has two functions: food intake and oral environment maintenance. In the food intake function of saliva, digestive effects such as the formation of food masses and digestive enzymes, solubilization of taste stimulating substances, and secretion of gastrin It shows the action of maintaining the taste. In the oral environment maintenance function, it exhibits a self-cleaning effect of teeth or mucous membranes, a recalcification action of teeth, an antibacterial action, an immune action, a tissue repair promoting action by growth factors, and an anti-inflammatory action.

Saliva is composed of 99.5% moisture and 0.5% electrolyte, mucus, glycoprotein, enzymes, and antibacterial substances, and is secreted by the salivary glands into the oral cavity. . In this case, when the saliva secreted is less than 0.1 ml, it is called dry mouth (Xerostomia), and is the most common clinical symptom associated with salivary glands.

This reduction in saliva secretion, i.e., xerostomia, is accompanied by abnormalities and metabolic diseases of the salivary gland itself (e.g., Bassedow's disease, sugary mildew, etc.) or collagen diseases caused by radiation therapy or mumps. do. In addition, the function of the salivary glands is reduced by stress factors, side effects of various medicines, and aging.

Aquaporins (AQPs), which play an important role in salivation, are water channel proteins found in the cornea, kidneys, liver, and skin. Aquaporin has various subfamily from AQP0 to AQP12. Expression of AQP1 is concentrated in capillary endothelial cells and myoepithelial cells, whereas when AQP5 is deleted, it secretes hypertonic saliva with a significantly reduced capacity. AQP5 plays an important role in saliva production.

The decrease in saliva secretion, as a result of dry mouth, causes the tongue to turn red, sometimes cracked, and patients with decreased salivation complain of pain during feeding and pain in chewing or swallowing. This can lead to facial pain and cause acute facial pain, causing discomfort in the mouth, or taste disorders and pronunciation disorders, causing denture instability, dental caries, gingivitis, mucosal ulcers in the mouth, bad breath and dry mouth. .

They mainly complain of abnormalities in chewing function and language function, and severe bad breath and decay occur, and depending on the degree, they experience severe pain due to burning of the oral mucosa or ulceration of the oral mucosa. Although topical application of artificial saliva is used as treatment, its effectiveness is limited and limited. As saliva secretion accelerators, anerol trithion and sevimelin hydrochloride, known as muscarinic receptor agonists, are used, which have unstable effects and functional problems of digestive system side effects such as nausea, vomiting, loss of appetite, and abdominal discomfort. There are some drawbacks, such as. Therefore, there is an urgent need for the development of a composition for promoting salivation of natural ingredients without side effects different from the compounds already known to have a saliva promoting effect.

Functional food according to another embodiment of the present invention includes a composition for preventing or treating the inflammatory pain.

Hereinafter, the present invention will be described in more detail.

As used herein, the term'extract' has a meaning commonly used as a crude extract in the art as described above, but broadly also includes a fraction in which an extract is additionally fractionated. That is, the extract includes not only those obtained using the above-described extraction solvent, but also those obtained by additionally applying a purification process. For example, a fraction obtained by passing the extract through an ultrafiltration membrane having a constant molecular weight cut-off value, separation by various chromatography (made for separation according to size, charge, hydrophobicity or affinity), etc. The fraction obtained through the purification method is also included in the extract of the present invention.

The extract used in the present invention may be prepared in powder form by additional processes such as distillation under reduced pressure and freeze drying or spray drying.

The term'comprising as an active ingredient' in the present specification means to include an amount sufficient to achieve the efficacy or activity of the extract according to the present invention. The present invention is a composition extracted from a natural plant material, and even when administered in excess, there is no side effect on the human body, so the upper limit of the amount of the extract contained in the composition of the present invention can be carried out by a person skilled in the art within an appropriate range.

The composition for preventing or treating inflammatory pain according to an embodiment of the present invention is to include cinnamon extract as an active ingredient.

Cinnamon is a member of the Lauraceae family, native to southern China, Vietnam, Sri Lanka, Indochina, and Korea (Jeju). As a main component of cinnamon, cinnamic aldehyde, eugenol, and the like have been known, and since ancient times, various types such as antiperspirants, antipyretics, and painkillers have been used.

Physiologically active substances, such as cinnamic aldehyde and eugenol, have a unique flavor, and thus are widely used as health supplements and medicines. Liquid products using cinnamon generally extract extracts of soluble substances in cinnamon Or it is prepared by adding a concentrated concentrate. The pharmacological efficacy of cinnamon is known for its anti-allergic effect, antibacterial effect, anti-ulcer effect, and hepatitis B virus suppression effect. In addition, it is known to have an antiseptic effect that promotes intestinal peristalsis and suppresses abnormal fermentation in the intestine.As a natural antibacterial agent that suppresses microbial contamination and growth, research for extensive use as food additives, pharmaceuticals, and industrial materials has been actively conducted. have. However, the results of pain-related research have been very scarce, and in particular, the effectiveness in generating and preventing inflammatory pain has hardly been proven.

When using the cinnamon extract, it is specialized in inflammatory pain, and can effectively suppress or alleviate the inflammatory pain.

Inflammatory pain referred to in the present invention includes postoperative, post-traumatic pain, arthritis (rheumatic) or osteoarthritis pain and pain associated with damage to the joints, muscles and tendons as in the case of axial lower back pain. Pain that occurs when there is tissue damage or inflammation.

The inflammatory pain may include acute inflammatory pain or acute facial pain caused by oral disease.

More specifically, the inflammatory pain may be caused by trauma, surgery, infection and various oral diseases, and may include acute inflammatory pain or acute facial pain.

The acute facial pain is also referred to as acute oral facial pain or acute facial pain, and is generally temporary to the maxillofacial area such as the temporomandibular joint (jaw joint), jawbone (chin), face (face), mouth (tongue or cheek), head, neck and shoulders. Or, it means periodic acute pain, which can be distinguished from chronic pain caused by periodontal disease, etc., which may occur during dental treatment, scaling, or other dental hygiene procedures, and sometimes accompanied by sudden or regular pain without certain cause. Speak.

The oral disease may include dental caries, gingivitis, mucosal ulcers in the oral cavity, bad breath and dry mouth.

In the present invention, the oral disease is a concept that includes all irrespective of the pathology if it is a disease that occurs in the oral cavity, but for the purposes of the present invention, it may preferably mean oral disease due to oral immunity reduction.

Dental caries (cavity) refers to an oral disease in which tooth decay destroys sugar, destroys the enamel or dentin of the tooth, and the teeth are pierced and turn black.

Periodontitis (periodontitis), also called periodontitis, is a disease that occurs mainly on the gums and bone tissue, and in the case of chronic infection, it means periodontal disease in which cell tissue is destroyed to lose teeth.

Mucosal ulcers in the oral cavity are inflammations of the mucous membranes of the mouth and around the mouth, mainly due to infections such as bacteria, viruses, and fungi. Stress, fatigue, hormonal changes, menstrual cycles, and sudden weight changes affect the onset. , Oral lubrication, is also caused by a decrease in saliva secretion, which can inhibit pathogen attachment in the oral cavity by combining with pathogens.

Halitosis (halitosis) is often referred to as bad breath, and due to acquired systemic diseases, saliva protein, food residues, etc., are decomposed by microorganisms, and the amino acids generated are mitigated by deoxidase or amino enzymes, causing odor. It is a disease.

Dry mouth (xerostomia) is a symptom in which saliva is not continuously secreted by any cause, causing the mouth to dry out. The amount of saliva may decrease due to systemic causes such as Sjogren's syndrome, anemia, diabetes, nutrient deficiency, and aging. , In addition to taking a variety of drugs, it can also be caused by diseases of the nervous system.

Saliva is secreted by three large salivary glands of the parotid gland, submandibular gland and sublingual gland, and small salivary glands evenly distributed in the oral cavity. When the function of these tissues decreases, the secretion of saliva decreases, resulting in symptoms of dry mouth. When dry mouth appears, the protective effect in the mouth by salivary solutions, proteins, and mucins is markedly reduced, resulting in destruction of salivary tissue. When saliva secretion decreases and develops into chronic dry mouth syndrome, it changes pronunciation, makes food chewing activity and skipping difficult, causes burning sensation in the mouth, and increases the risk of tooth decay and oral disease.

In actual clinical practice, pilocarpine or sevimelin is used to treat or alleviate dry mouth syndrome. In the case of administration of pilocarpine at a dose of 15-30mg per day, the effect of pilocarpine was about 25%, and after administration It is known to be effective in about 50% of patients.

Dry mouth is generally caused by a decrease in saliva secretion. Saliva secretion is made by interaction of several complex factors, and it is known that aquaporins (AQPs) play an important role in saliva secretion.

Aquaporin 5 (Aquaporin 5, AQP5) is a characteristic water channel protein component that exists from AQP0 to AQP9 depending on the type of organs, such as the lens of the eye, kidney, gastrointestinal tract, liver, and pancreas. It has been reported that AQP5 is abundantly expressed in the selective production of aquaporin-5 (AQP5) by interferon-alpha.

On the other hand, saliva can also be promoted by agents containing electrolytes, such as muscarinic agonists or adrenergic agonists. Amylase is a representative digestive enzyme found in saliva and serves to break down starch. Amylase is expressed in cell organs or progenitor cells and glandular cells of the salivary glands that are involved in protein secretion in the pancreatic progenitor cells of rats, and can be used as a preferred marker to judge the function of the salivary glands.

Currently, many studies have been conducted to treat salivation, but the basic treatment is difficult and popular treatments are mainly performed. You can increase your fluid intake to keep your mouth moist, or use sugar-free chewing gum, take lemon-flavored drinks, use artificial saliva, and use a citric acid-added fern solution. In addition, although saliva preparations for sprays developed by dogs and electric stimulation methods have been used experimentally, research into the development of therapeutic agents for hyposalivation has been conducted because its effects are temporary and not limited. However, studies on dental caries, gingivitis, oral mucosal ulcers, bad breath and dry mouth associated with alleviating salivation have been very scarce, especially in the prevention of acute inflammatory pain and acute facial pain caused by these oral diseases. The effectiveness has been little proven.

When the cinnamon (cinnamon) extract is used, it is specialized in oral diseases, and can effectively suppress or alleviate the inflammatory pain caused by it.

The cinnamon (cinnamon) extract includes extracting using an extraction solvent selected from the group consisting of water, C₁ to C급 lower alcohols, and mixtures thereof.

More specifically, on the basis of 100 Ml of alcohol having 1 to 6 carbons or 100 mL of water, it is obtained by pulverizing 10 to 20 g of natural products, 1 to 2 hours of reflux time and 70 to 90% of alcohol or water having 1 to 4 carbons.

The leaching method proceeds for 15 to 30° C. for 24 to 72 hours, and water or alcohol having 1 to 6 carbon atoms of 50 to 100% is used as an extraction solvent. More specifically, it proceeds for 20 to 25° C. for 30 to 54 hours, and the extraction solvent is by water or alcohol having 1 to 6 carbon atoms of 70 to 80%.

The ultrasonic extraction method proceeds the reaction for 30 to 50°C, 0.5 to 2.5 hours, and the extraction solvent is by water or alcohol having 50 to 100% carbon number 1 to 6. Specifically, it is extracted at 40 to 50°C for 1 to 2.5 hours, and is extracted with water or an alcohol having 1 to 6 carbon atoms of 70 to 80% as an extraction solvent.

The extraction solvent may be used 2 to 50 times based on the weight of the sample, more specifically 2 to 20 times. For extraction, the sample may be left for 1 to 72 hours for leaching in the extraction solvent, and more specifically, for 24 to 48 hours.

After extraction, the extract can be fractionated by sequentially applying a new fraction solvent. The fractionation solvent used for fractionation is any one or more selected from the group consisting of water, hexane, butanol, ethylacetic acid, ethyl acetate, methylene chloride and mixtures thereof, preferably ethyl acetate or methylene chloride.
