Objectives : This study focused on Schisandrae Fructus (SF) and Perilae Folium (PF), traditional medicine herbs and health functional food in Korea, Japan and China. We investigated various pharmacological activities that include a potential source of free radical scavenging, anti-viral, anti-microbial, anti-allergy and anti-inflammatory activities. Methods : We conducted an investigation of total contents of phenolic and flavonoid compounds in these single herbal extraction with/without combined to mixture. We also measured antioxidant activities such as DPPH free radical scavenging, SOD-like scavenging, nitrite scavenging and hydroxyl radical scavenging activities, xanthine oxidase inhibition, linoleic acid peroxidation inhibition, and reducing power. Results : As the results, contents of total phenoilc compounds and flavonoids were higher in those of PF than those of SF. Those of SF+PF mixture showed the synergy effects compared with those of SF and PF single extractions. Activities of DPPH free radical and SOD-like scavenging in 1 mg/mL concentration increased in dose dependent manners. That of SF increased compared with that of PF. That of SF and PF mixture also increased compared with that of BHA as a positive control. The other antioxident activities also showed similar to patten of activity of DPPH free radical scavenging. When combined to SF and PF extractions, there was showed synergic effect compared with those of BHA, excepted activities of xanthine oxidase inhibition and reducing power. Taken together, SF and PF have high phenolic and flavonoid compounds content furthermore, antioxidant activities in SF and PF mixture showed more synergy effect compared with those of BHA. Conclusions : Therefore, these findings suggest that SF and PF mixture may offer functional materials potential for development of functional beverage. But further studies are needed for the identification of the active compounds.

Spirodela polyrhiza(L.) Schleid (Lemnaceae) have been used as a traditional drug in treating urticaria and itching. However, the exact role of Spirodela polyrhiza in allergic reaction has not been clarified yet. Type 1 hypersensitivity (immediate hypersensitivity), popularly known as allergy, is a major clinical problem in humans. It has been found that the histamine release from mast cells is an essential step in the pathological process of immediate hypersensitivity. In the present study, the effect of aqueous extract of Spirodela polyrhiza (AESP) on immediate hypersensitivity was investigated. AESP inhibited the antigen-induced passive cutaneous anaphylaxis (PCA). AESP in vitro exhibited a dose-dependent inhibition of degranulation in RPMC stimulated by compound 48/80. AESP also suppressed the morphological changes and the increase of intracellular free calcium level induced by compound 48/80. These results suggest that inhibitory effect of AESP on immediate hypersensitivity may be mediated through the decrease of intracellular free calcium levels, and AESP importantly contributes to the treatment of anaphylaxis and may be useful for other allergic disease.

Objective : To present a criteria for acupuncture standardization, which will improve quality of acupuncture and secure safety, through studies of the biocompatibility of acupuncture. Methods : The acupunctures distributed in Korea were studied. The chemical composition, elasticity, and the solidity of the acupuncture's metal material was analyzed. Results & Conclusions : 1) The acupunctures distributed in Korea were all produced with ST304. Because acupuncture is used on a living body, the corrosion resistance, allergy proof and magnetism of the metal material should be considered. In this point, STS316 stainless steel would be more suitable than ST304. 2) The elasticity and solidity of the acupuncture's metal material distributed in Korea meet the medical instrument standards of the Korea Food and Drug Administration. But since the standards are only roughly outlined, the criteria should be realized and standardized.

The flowers of Lonicera japonica Thunb. (Caprifoliaceae) have been used as a traditional effective drug in treating bacillary dysentery, purulence. However, the exact role of Lonicera japonica in allergic reaction has not been clarified yet. Immediate hypersensitivity, popularly known as allergy, is a major clinical problem in humans. It has been found that the histamine release from mast cells is an essential step in the pathological process of immediate hypersensitivity. In this study, the effect of aqueous extract of Lonicera japonica (AELJ) on allergic reaction was investigated. AELJ inhibited the compound 48／80-induced anaphylactic reactions and antigen-induced passive cutaneous anaphylaxis (PCA). AELJ in vitro exhibited a dose-dependent inhibition of degranulation in RPMC stimulated by compound 48／80. AELJ also suppressed the morphological changes and the increase of intracellular free calcium level induced by compound 48／80. These results suggest that inhibitory effect of AELJ on allergic reaction may be mediated through the decrease of intracellular free calcium levels, and AELJ importantly contributes to the treatment of anaphylaxis and may be useful for other allergic disease.

Chungyangeum (CYE) is a newly designed herbal drug formula for the purpose of treating atopic dermatitis. The aim of the present study is to elucidate whether and how CYE modulates the allergy inflammation in vitro and in vivo. We investigate to ascertain the pharmacological effects of CYE on both compound 48/80 or histamine-induced scratching behaviors and 2, 4-dinitrochlrobenzene (DNCB)-induced atopic dermatitis in mice. Additionally, we attempted to determine the effects of CYE on lipopolysaccharide (LPS)-induced inflammatory responses in macrophages. The findings of this study demonstrated that CYE reduced compound 48/80 or histamine-induced scratching behaviors and DNCB-induced atopic dermatitis in mice. The CYE inhibited the production of inflammatory cytokines as well as the activation of NF-${\kappa}B$ and caspase-1 in stimulated macrophages. Collectively, the findings of this study provide us with novel insights into the pharmacological actions of CYE as a potential molecule for use in the treatment of allergic inflammation diseases.

Atopic dermatitis (AD) is a chronic and relapsing inflammatory disease that affects 1%-20% of people worldwide. Despite affecting many people, AD current treatments, such as corticosteroids and calcineurin inhibitors, have not only harmful secondary effects but are also often ineffective. Therefore, natural nontoxic compounds are on high demand for developing new effective AD treatments. Panax ginseng Meyer has been used traditionally for its promising healing and restorative properties to treat many diseases including skin disorders, reason why in this review we want to explore the research performed with AD and P. ginseng as well as determining its potential for new drug development. Previous researches have shown that P. ginseng has positive effects in AD patients such as lower eczema area and severity index, transepidermal water loss, and immunoglobulin E levels and better quality of sleep. In vivo animal models, as well, have shown positive results to P. ginseng and derived ginsenosides, such as the decrease of transepidermal water loss, immunoglobulin E levels in serum, allergy-related cytokines, and downregulation of NF-κB, MAPK, and Ikaros pathways. All of these previous data suggest that P. ginseng and its derived ginsenosides are undoubtedly a nontoxic effective option to treat AD.

Asthma is characterized by chronic inflammation and respiratory tract remodeling. Peroxisome proliferator-activated receptors (PPARs) play important roles in the pathogenesis and regulation of chronic inflammatory processes in asthma. The role of PPARγ has been studied using synthetic PPARγ agonists in patients with asthma. However, involvement of PPARα/δ has not been studied in asthma. In the present study, we investigated if elafibranor, a PPARα/δ dual agonist, can modulate ovalbumin (OVA)-induced allergic asthma, which is a potential drug candidate for non-alcoholic fatty liver in obese patients. Elafibranor suppresses antigen-induced degranulation in RBL-2H3 mast cells without inducing cytotoxicity in vitro. In mice with OVA-induced allergic asthma, the administration of elafibranor suppressed OVA-induced airway hyper-responsiveness at a dose of 10 mg/kg. Elafibranor also suppressed the OVA-induced increase in immune cells and pro-inflammatory cytokine production in the bronchoalveolar lavage fluid (BALF). Histological studies suggested that elafibranor suppressed OVA-induced lung inflammation and mucin hyper-production in the bronchial airways. In addition, elafibranor suppressed OVA-induced increases in serum immunoglobulin E and IL-13 levels in BALF. Conversely, the present study suggests that elafibranor has the potential for use in patients with allergic asthma.

The purpose of this study was to examine the anti allergic effect in vivo and in vitro, and to observe single and four weeks repeated toxicity in mice of Bangpung-galgeun-tang (BGT). We investigated anti DNP IgE-mediated passive cutaneous anaphylaxis in rodents and compound 48/80-induced active systemic anaphylatic shock in mice after oral administration with BGT of 0.4 g/kg and 0.8 g/kg for 8 days, and also examined MTT assay, ${\beta}-hexosaminidase$ activity, IL-4 and $TNF-{\alpha}$ from RBL-2H3 and $TNF-{\alpha}$ from Raw264.7 after pre-treatment with BGT of 0.25 mg/ml, 0.5 mg/ml, 1 mg/ml and 2 mg/ml. To ascertain safety and toxicity of BGT, we divided into single and four weeks repeated administration test. In single test, three groups were administrated different dosages and routes (2 g/kg/i.p., 4 g/kg/i.p. and 15 g/kg /p.o.) of BGT, and in four weeks repeated test, 0.8 g/kg BGT was administrated. Control groups were administrated with only saline according to on Korean Food and Drug Administration, respectively. We observed attentively motality, abnormal clinical sign, body weight change, organ weight, AST and ALT of mice after BGT administration. BGT inhibited passive cutaneous anaphylaxis and active systemic anaphylatic shock by oral administration. All the concentrations of BGT from 0.25 to 2 mg/ml didn't have an effect on cell viability and cytotoxicity. In RBL-2H3, ${\beta}-hexosaminidase$ release, IL-4 and $TNF-{\alpha}$, and in Raw264.7, $TNF-{\alpha}$ were significantly reduced by treated all concentrations of BGT. During toxicity experiment period, there was no difference in body weight change, organ weight, AST and ALT among different dose groups. Death were found 3 mice from day 2 to day 3 in single test i.p. group. (2 g/kg, 4 g/kg). Several individuals of single test i.p. group were observed that decreased locomotor activity, exophthalmos, bloodshot eyes, loss of eyesight and so on in early period after administration. But there was no difference in clinical signs among p.o. group. These results indicate that BGT have inhibition effects on allergy and suggest that no observable effect level of the test orally administration was considered to be more than 2 g/kg in mice under the conditions employed in this study.

Recent increases of asthma and allergies in childhood made the need for a standardized approach to international and regional comparisons of their prevalence and severity. To address these issues, 'International Study of Asthma and Allergies in Childhood (ISAAC)' is currently underway. In Korea, 'Nationwide Study of Asthma and Allergies in Korean Children' began in 1995 according to ISAAC protocol. ISAAC written and video questionnaires were used in this survey, but their reliability and validity were not evaluated properly yet. In this study, our aim was to evaluate the reliability and validity of two kinds of questionnaires and their usefulness in international and regional comparisons. The test and retest of two questionniares were completed by male(n=110) and female(n=111) middle school students with two and three weeks interval each. Kappa(or weighted kappa) were calculated from each questions and validity coefficients were estimated from those statistics. In Korean version of written questionnaire, the questions for allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and food allergy proved to have high kappa values (or weighted kappa values) and validity coefficients and they can be used in further studies without any correction. But some questions about asthma(especially nocturnal cough, wheezing in exercise, and severe asthma) and drug allergy need to be revised for better under-standing to study subjects. Video questionnaire has the same degree of reliability and validity when compared to written questionnaire and this is the unexpected result. Accordingly, it also need to be revised to overcome the racial and cultural differences of the study subjects. In conclusion, the Korean version of written and video questionnaires may be considered to be useful methods in international and regional comparisons of asthma and allergic diseases in childhood after correction of some questions.
