인삼이 면역계 질환의 일종인 과민성 반응에 대한 치료약으로서의 가능성을 연구하기 위해서 in viva와 in vitra실험을 수행하였다. in vitra실험으로서는 hyaluronidase의 활성을 지표로 삼았으며, in viva실험에서는 mouse이각, rat등피부, 복강 비만세포, 그리고 guinea pig의 ileum에서 면역반응에 대한 아답타겐의 작용을 관찰하였다. in uitra 실험에서는 hyaluronidase와 histamine 분비를 항알레르기 작용의 지표로 사용하였다. hyaluronidase의 경우 그 활성은 Cacl2로 활성화 시키기 전이나 후에 모두 아답타겐(100, 50, 및 10 mg/ml)에 의해서 현저하게 억제되었다. 한편 rat 복강 비만 세포에서의 histamine유리 시험에서는 아답타겐(0.5, 1, 5mg/ml)이 histamine유리가 증가되었다. Guinea pig의 ileum 평활근에서는 아답타겐이 평활근 자극 작용없이 항히스타민 효과률 나타내었다. in uiua 실험의 첫 단계로 우리는 혈관 투과성에 미치는 아답타겐의 효과를 mouse 이각과 rat 등피부에서 관찰하였다. Mouse이각에서의 실험에서는 hoistamine, serotonin, 그리고 LTC4로 challenge하여 관찰한 결과 histamine과 serotonin의 경우, 혈관투과성 항진은 아답타겐(50-400mg/m1)에 의해서 유의성있게 억제되었으나, rat 등 피부에서는 mouse에서와는 달리 48-hr PCA가 증가 되었고, histamine에 의한 혈관투과성 항진은 아답타겐에 의해 영향을 받지 않았다. 반면에 compound 48/80과 serotonin에 의한 혈관투과성 항진은 mouse 의 경우에서처럼 아답타겐에 의해 억제되었다.

Background: Intraoperative and postoperative ocular complications are rare. We retrospectively investigated the abnormal ocular findings in patients who underwent arthroscopic shoulder surgery. Methods: The records were investigated of patients who underwent shoulder arthroscopic surgery at our hospital between January 2018 and March 2019. Ocular complications were confirmed by review of medical records. We performed logistic regression analysis to defined the main factors associated with ocular complications. Results: The overall prevalence of postoperative ocular complications was 8.5% (18/211). A significant association was found between anti-adhesion barrier agent and ocular complications (p=0.020). Conclusions: Anti-adhesion barrier agent used during surgery may be the cause of postoperative ocular complication.

소아천식은 기도의 만성 염증 및 과민반응을 특징으로 나타내고 있어 염증을 일으키거나 알레르기 반응을 일으키는 물질로부터 차단하는 방법이 효과적임을 현대의학에서 이미 밝히고 있다. 한의학에서는 천증(喘證)에 본디 뿌리 깊은 근원(천유숙근(喘有夙根))이 있다고 간주하여 허약한 체질은 내적인 요인이고, 풍한침습(風寒侵襲)은 유발요인이며, 담음복폐(痰飮伏肺)와 신기휴허(腎氣虧虛)는 재발의 근본이라고 하였다. 본 연구에서는 소아 천식에 구마황(灸麻黃), 은행(銀杏), 건강(乾薑), 오미자(五味子), 백전(白前), 구백부(灸百部), 소자(蘇子) 등을 사용하였고, 경우에 따라 황기(黃?) 혹은 선령비(仙靈脾)를 추가하여 正氣(正氣)를 강화시키는 목적으로 사용하였다. 약리학적 연구에 따르면 마황과 건강, 오미자 등은 모두 기도의 염증세포 침윤(浸潤)를 억제하고 항알레르기 효과가 있으며, 건강과 오미자는 또한 히스타민에 대한 길항효과(拮抗效果)도 있는 것으로 알려져 있다. 은행 추출물은 혈소판 활성화 수용체에 대한 길항작용을 갖고 있으므로 이러한 물질들로 인한 기관지의 경련을 방지하여 천식증상을 왕화시킨다. 구백부(灸百部)는 지해(止咳)효과가 뛰어나다. 소아천식에 대한 치료는 표본동치(標本同治)의 원칙을 지키며, 증상이 완화된 단계에서도 중약 투여를 1-2개월 지속시키는 것이 중요하다. 소아에게 있어서 천식증상이 완화된 후 어혈(瘀血) 상태가 성인에 비해 심하지는 않지만, "구병필어(久病必瘀)"의 결과에 유의할 필요가 있다. 천식이 장기간 지속되면 필히 혈액순환 장애가 수반되므로 천궁(川芎)이나 단삼(丹蔘) 등의 활혈제(活血劑)를 가미하여 사용하면 효과를 높일 수 있다. 결론적으로 소아의 천식은 항염증, 평천(平喘), 화담(火痰), 지해(止咳)와 더불어 보신익기화어(補腎益氣化瘀)의 약물을 병행하여 사용하는 것이 바람직하며, 단순한 중약 투여는 일부 양약에 의한 소아성장에 미치는 영향을 피할 수 있어 더 많은 임상연구가 이어져야 한다.

The number of allergic contact dermatitis patients is steadily increasing but a proper reliability treatment guide is not prepared in Oriental Medicine. Also, the number of clinical cases on allergic contact dermatitis is not sufficient in Oriental medicine. As such, the facial flushing of allergic contact dermatitis which has been improved by infra-red therapy is significant in its treatment purpose. We reported on 43-year old male patient with allergic contact dermatitis. We treated him with herbal concoction, acupuncture, infra-red therapy and cupping therapy. We have received a good result in this case by using the combination of infra-red therapy. We reached a conclusion that using infra-red therapy can improve the facial flushing of patient with allergic contact dermatitis. However, further research on the effect of infra-red therapy for these symptoms is desired.

The purpose of this article is to cope with the abuse of antibiotics in the clinic, to determine the necessity of antibiotic administration, to share information on the selection and proper use of appropriate antibiotics, and to increase the appropriateness of antibiotic prescription through continuous monitoring. In line with the latest research and guidelines trends of various agencies, we will supplement the antibiotic prescription guidelines and use them for the treatment in Apple Tree Dental Hospital. Specially, by history taking and the penicillin allergy test, amoxicillin is prescribed as a primary selective antibiotic for 1 day. The complaints and treatment effects of the first antibiotic should be evaluated at the next visit. If the primary antibiotic was ineffective, we replaced it with a broad-spectrum antibiotic. If there was no improvement in symptoms, the patient would be referred to upper grade hospital. The staff of the Apple Tree Dental Hospital regularly monitored and educated antibiotic prescriptions. The current guidelines should be supplemented continually and positively affect the abuse of antibiotics and the habit of dental practice.

Ginseng is one of the most commonly used herbal medicines and health foods. Korean red ginseng (KRG; Panax ginseng C.A. Meyer) extract is known to have potential therapeutic activities, such as anti-viral effects, the amelioration of food allergies, anti-oxidant effects, and obesity reduction. Nevertheless, no reports have been issued the modulatory effects of KRG extract on the activity of cytochrome P450 (CYP). In the present study, we investigated the modulatory effect of KRG extract in vitro and in vivo by using pooled human liver microsomes and male ICR mice. When human liver microsomes were incubated with KRG extract at 0.01-10 mg/ml, CYP1A2, 2B6, 2C19, 2D6, and 3A were not significantly inhibited by KRG extract, although CYP2B6 was slightly inhibited. Mice were orally administered KRG extract at 50, 250, or 500 mg/kg daily for 3, 7, or 14 days. However, the activities of CYPs in mouse livers were not significantly different from those of vehicle-treated controls. In conclusion, no significant ginseng-drug interaction was observed. KRG extract did not significantly modulate the activities of CYPs in vitro or in vivo.

Moraceae comprise a large family of sixty genera and neary 1,400 specieses, including important groups such as Artocarpus, Morus, and Ficus. In particular, Morus(mulberry) is a small genus of tree and shrubs found in temperate and subtropical regions of the Northern hemishere and has been widely cultivated in China and Korea, In addition, the root bark of mulberry tree have been used as an antiphlogic, diuretic, and expectorant in white medicine, and the crude drug is known as "Sangbaikpi" in Korea. Recently, some papers have been published reporting the hypotensive effect, antiviral effect, antifungal effect, inhibitory effect of cAMP-phosphodiesterase, and anticancer effect of this extract. Little is known about that Cortex mori could have been an antiallergic effect. The purpose of this study was the development of an antiallergic agent with an antiallergic effect from Cortex mori. For this, several in vivo and in vitro experimental models were used. Results are 1) Cortex mori inhibited the compound 48/80-induced degranu-lation, histamine release and calcium uptake of rat peritoneal mast cells, 2) compound 48/80-induced anaphylactic shock and cutaneous reaction were significantly inhibited by pretreatment of Cortex mori, and 3) Cortex mori inhibited the ovalbumin-induced late astmatic reaction. From the above results it is suggested that Cortex mori has some substances with an antiallergic activity. Our final purpose of this study is to develope the new drug with an antiallergic activity from Cortex mori

Purpose: Radiocontrast media are widely used in medical imaging to improve diagnostic accuracy. However, studies on the adverse reactions of radiocontrast media in children are limited. We aimed to describe the characteristics of adverse reactions to radiocontrast media among children who had a computed tomography scan or magnetic resonance imaging in a tertiary university hospital. Methods: We retrospectively collected data on adverse reactions to radiocontrast media by the reporting system of a tertiary university hospital. We selected data from children under the age of 19 from July 2011 to December 2017 and analyzed their characteristics. We focused mainly on the characteristics of the index case which is defined by the first adverse event of each subject. Results: During the period, a total of 88,050 radiocontrast media-enhanced imaging studies were performed and 184 cases of adverse reactions were reported. A total of 71 were identified as index cases. Forty-nine (69.0%) were male and the mean age was $12.7{\pm}3.2$ years. The incidence of radiocontrast media-related adverse reactions was 0.09% and severe reactions were 0.002%. The most common clinical feature was skin manifestations (54.9%), followed by gastrointestinal symptoms (40.8%) and neuropsychiatric symptoms (7.4%). Conclusion: Adverse reactions to radiocontrast media rarely occur in children and the incidence of severe reactions is low. Most reactions are mild and are related to the skin and gastrointestinal system. This report would provide good evidence for establishing a management strategy in children scheduled for imaging studies using radiocontrast media.

The chicken meat has been reported as one of the food causing allergic reactions predominantly to Korean. At present, several in vitro tests for immunoglobulinG (IgG)-mediated as well as IgE-mediated food allergy are available. 13 clinically chicken meat-allergic patients were investigated together with 4control subjects for identification of chicken meat-specific reactivity by ELISA. Also, protein profile and IgE, IgGtotal and IgG4-reacting allergens were detected by means of sodium dodecyl sulfate-polyacrylamide gel electro-phoresis (SDS-PAGE)and immunoblotting. Chicken meat extracts were prepared as raw, heated, heat and simulated gastric fluid (SGF) treated samples to characterize the stability of allergen to physicochemical treatment. SDS-PAGE revealed 9~200 kDa bands. And in immunoblotting 7 sera were identified most major bands between 10 and 78 kDa. In case of IgE, six proteins (17, 26, 35, 40, 78 kDa) were predominant in heat-treated extract, and the one (35 kDa) was present in SGF-treated preparations. In case of IgG$_{total}$ and IgG4, most of them showed a patters simmilar to IgE. There were significant differences (P<0.05) in IgE, IgG$_{total}$ , IgG4 Abs to chicken meat between the allergic and control subjects in ELISA. In addition, the concentration of IgG4Abs in the challenge-positive subjects was significantly higher than that of control subjects. It is considered that the specific IgE response to chicken meat was rarely prevalent to Koreans. However, the specific IgG4 response play an important role in the development of allergic symptoms.

Background : Asthma causes recurrent episodes of wheezing, breathlessness, chest tightness, and cough. These symptoms are usually associated with widespread but variable airflow limitation that is partly reversible either spontaneously or with treatment. The inflammation also causes an associated increase in airway responsiveness to a variety of stimuli. Method : Of the 403 adult bronchial asthma patients enrolled from March 1992 to March 1994 in Allergy Clinics of Severance Hospital in Yonsei University, this study reviewed the 97 cases to evaluate the treatment effects and to analyse prognostic factors. The patients were classified to five groups according to treatment responses ; group 1 (non control group) : patients who were not controlled during following up, group 2 (high step treatment group) : patients who were controlled longer than 3 months by step 3 or 4 treatment of "Global initiative for asthma, Global strategy for asthma management and prevention" (NHLBI/WHO) with PFR(%) larger than 80%, group 3 (short term control group) : patients who were controlled less than 1 year by step 1 or 2 treatment of NHLBI/WHO, group 4 (intermediate term control group) : patients who were controlled for more than 1 year but less than 2 years by step 1 or 2 treatment of NHLBI/WHO, group 5 (long term control group) : patients who were controlled for more than 2 years by step 1 or 2 treatment of NHLBI/WHO. Especially the patients who were controlled more than 1 year with negatively converted methacholine test and no eosinophil in sputum were classified to methacholine negative conversion group. We reviewed patients' history, atopy score, total IgE, specific IgE, methacholine PC20 and peripheral blood eosinophil count, pulmonary function test, steroid doses and aggrevation numbers after treatment. Results : On analysis of 98 patients, 20 cases(20.6%) were classified to group 1, 26 cases(26.8%) to group 2, 23 cases(23.7%) to group 3, 15 cases(15.5%) to group 4, and 13 cases(13.4%) to groups 5. There were no differences of sex, asthma type, family history, smoking history, allergic rhinitis and aspirin allergy among the groups. In long term control group, asthma onset age was younger, symptom duration was shorter, and initial pulmonary function was better. The long term control group required lower amounts of oral steroid. had less aggrevation during first 3months after starting treatment and shorter duration from enrollment to control Atopy, allergic skin test, sputum and blood eosinophil, total IgE, nonspecific bronchial responsiveness was not significantly different among the groups. Seven out of 28 patients who were controlled more than 1 years showed negatively converted methachloine test and no eosinophils in the sputum. The mean control duration was $20.3{\pm}9.7$ months and relapse did not occur. Conclusion : Patients who had asthma of onset age younger, shorter symptom duration, better PFT, lower treatment initial steps, lower amounts of steroid needs and less aggravation numbers after starting treatment were classified in the long term control groups compared to the others.
