From the ancient times, herbs, animals and minerals were used as natural medicine to cure human disease in diverse ways. One of the representative forms in oral intake is decoction. But medicinal decoction degenerates as time passes just as all foods do by the environmental factors, such as micro-organism, enzyme, light and the air. Nowadays, as medicinal decoctions are kept in bottles and retort pouch for longtime, some standard data for preservation is necessary. In order to measure the standard statistics for safe preservation, Youngsunjetongeum used to treat rheumatism, and gout 'were used. According to this experiment which measured pH, specific gravity, analgesic effect and anti-inflammatory effect, the results were as follows: 1. No remarkable change was found in pH and in the specific gravity of decoction. 2. As for the analgesic effect induced by acetic acid in mice, no remarkable decrease in its medicinal efficacy was found, until the 9th day, but it showed in its medicinal efficacy from the 11th day. 3. As for the resultant anti-inflammatory effect caused by vascular permeability, induced by carrageenin and acetic acid, no remarkable decrease in its medicinal efficacy was found until the 9th day, but showed decrease in its medicinal efficacy from 11th day. In conclusion, keeping the natural medicinal decoction more than 9 days should be avoided.

Acanthoic acid (AA) is a pimaradiene diterpene isolated from the Korean medicinal plant, Acanthopanax koreanum (Araliaceae), which has been traditionally used as a tonic and sedative as well as in the treatment of rheumatism and diabetes in korea. Proteinase-activated receptor-2 (PAR-2) agonist trypsin plays a role in inflammation, and human leukemic mast cells (HMC-l) express PAR-2. In the present study, the effect of acanthoic acid on production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and tryptase in trypsin-stimulated HMC-1 was examined. (omitted)

The possibility as an anti-inflammatory drug of Prunus davidiana which have been used in Korean folk medicine for treatment of neuritis and rheumatism was investigated on carrageenin-induced paw edema in rats. The MeOH extract exhibited potent inhibitory effect on carrageenin-edema rats when topically applicated. On the other hand, it did not show any effect when orally tested. It also had no influences on isolated ileum of guinea pig and anti-platelet aggregating activities. Thus, it appears from the present findings that the MeOH extract of P. davidiana may be utilizable only for the external treatment of inflammed sites. This study was also conducted to further isolation of flavonoids from the EtOAc soluble fraction and characterized as persiconin and isosakuranin by spectrometric analysis.

경구적으로 투여된 항원에 대해서 특이적으로 T세포의 기능과 항체산생이 억제되는 현상이 경구면역관용(oral tolerance)인 것이다. 지금까지 해석이 곤란하였던 이 현상에 대해서 최근 분자생물학적인 기법이 적용되기 시작한 결과, 이 현상에 관여하는 세포가 주로 $CD8^+$ T세포에의한 억제 혹은 $CD4^+$T세포의 불응답(unresponsiveness)에 기인하다는 것이 명백해졌다. 또한 각종 cytokine중 IFN$\gamma$, TGF$\beta$, IL-10 등이 이 현상에 있어 중요한 역할을 담당한다는 것이 밝혀지고 있다. 사실 경구면역관용은 말초면역관용을 야기한다는 것이 오래전부터 알려진 한 방도이다. 경구적으로 투여된 항원이 관용을 야기하는 일차적인 기전은 능동적인 억제의 발생 혹은 clone성 anergy(과민증에 대한 무감증)에 의거하는 것이다. 낮은 량의 경구투여항원은 능동적인 억제를 야기하기 쉬우나 반대로 높은 양의 경구투여항원은 clone성 anergy를 야기하는 경향이 있다. 능동적인 억제를 매개하는 조절세포는 경구면역관용에 의해서 격발된 후 TGF$\beta$및 IL-4와 같은 억제성 cytokine의 분비에 의해서 능동적 억제작용을 한다. 더구나 GALT(gut-associated lymphoid tissue)를 선별적으로 자극하는 항원은 Th2형 세포반응을 발생한다. 또한 이와같은 유도기구의 해석과 동시에 사람에서 면역반응의 이상으로 야기되는 관절 rheumatism이나 다발성경화증(multiple sclerosis) 그리고 각종 allergy도 이 경구면역관용을 이용하여 치료하는 것이 가능하게 되었다는 것이다.

The root of Aralia continentalis Kitagawa (Araliaceae) have been used as an analgesic and fever remedy, and for treatment of rheumatism in Chinese medicine, whereas the young leaves are used for ingredient of salad. Antioxidant activity of the young leaves of A. continentails was determined by measuring lipid peroxide produced when a mouse liver homogenate was exposed to the air at $37^{\circ}C$, using 2-thiobarbituric acid (TBA) and by evaluation the radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. Chromatographic separation of active fraction led to the isolation of six flavonoids, among which quercetin, hyperoside and kaempferol showed strong antioxidant activities, while 6"-O-acetyl astragalin, astragalin and trifolin were inactive. Adenosine, oleanolic acid 28-O-glucosyl ester and salsoloside C methyl ester isolated from the somewhat active BuOH fraction exhibited no antioxidant activities.

Sjögren's syndrome (SS) is an autoimmune rheumatic disease characterized by the presence of lymphocytic infiltration of exocrine glands and other organs. Due to the rarity of SS, it is frequently overlooked by dentists as a cause of xerostomia. Clinicians should be aware that patients may have oral complications from SS including oral mucosal pain caused by frictional damage. Use of the latest diagnostic criteria approved by the American College of Rheumatology/European League against Rheumatism in 2016 for SS diagnosis provides the advantage of early identification of patients who have not yet developed dry mouth symptoms. A case of primary SS with the chief complaint of oral mucosal pain caused by mucosal damage associated with dry mouth is presented here. This case represents the importance of recognizing oral complications of xerostomia caused by SS, and illustrates use of the latest diagnostic criteria to diagnose the suspected symptoms by dental clinicians, who typically might be the first medical professional to encounter these symptoms.

As the interest in oral health is increasing with quality of life. The most representative oral diseases include dental caries, periodontal disease, and malocclusion, as well as dry mouth and oral mucosa. Cinnamaldehyde have an antioxidant effect that has been studied not only to treat rheumatism and hypertension, but also to protect liver, and gastrointestinal tract, but there are few studies related to the control of oral diseases. The purpose of this study was the effect of enhanced orofacial pain when oral administration of cinnamaldehyde in the oral diseases. Cinnamaldehyde (5, 12.5, 25, and 50 mg/kg) orally administered at a dose of 1 mL, and the change in biological response was confirmed after a week. In addition, 5% formalin (30, 50 μL) was injected into TMJ and subcutaneous areas of the whiskers of rats to observe the change in the threshold of the improved orofacial pain model. As a result of the experiment, in the xerostomia model, drinking water was decreased in the cinnamaldehyde-administered group, feed intake and weight increased, and saliva was also increased compared to the naïve group. In particular, the most significant increase trend was observed at the concentrations of 25 and 50 mg/kg. In addition, it was confirmed that the pain behavioral response of the orofacial area improved by oral diseases decreased depending on the concentration of cinnamaldehyde. Based on these results, cinnamaldehyde effectively reduced symptoms related to xerostomia and showed improved pain relief in the orofacial areas.

Sea cucumbers are worm-like, leathery bodied, benthic, marine organisms with a branched gonad. There are over 900 species, and these organisms are capable of changing their mechanical state, regenerating their small appendages, and digestive tract. Additionally, sea cucumbers possess both commercial and therapeutical value. Furthermore, it is thought that the metabolites these organisms possess may give rise to their therapeutical value. The use of sea cucumbers in therapy can be traced back to the Ming dynasty, where they were eaten for their tonic properties against constipation, hypertension, and rheumatism. A plethora of studies have been conducted, whereby different metabolites were extracted from sea cucumbers and tested for different therapeutic properties. Herein, we review and discuss the anti-cancer, anti-microbial, anti-coagulant, anti-diabetic, antioxidant, and anti-inflammatory properties of the sea cucumber by assessing literature on PubMed and Google Scholar. Furthermore, the genome and epigenome of these remarkable species is discussed. With the immense data supporting the therapeutic properties of sea cucumbers, further studies are warranted, in order to develop novel and innovative therapeutic compounds for the benefit of human health from these fascinating marine organisms.
