The purpose of this study was to examine to observe single and four weeks repeated toxicity in mice of Bangpung-galgeun-tang (BGT). We investigated 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. 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.

본 연구는 콜린성 두드러기를 치료하기 위해 기존 제품으로는 정제를 사용하였다. 정제의 단점으로는 졸음유발 문제나 접근성 및 투여량 감소 문제가 있었으며 이를 해결하기 위해 세티리진 염산염을 함유한 Hydro-Gel을 제조하였다. 실험 방법은 점도, 겔화율, 팽윤도, 함량 평가, 투과성을 측정하였다. 연구에 따르면 세티리진 염산염을 함유한 하이드로 겔은 콜린성 두드러기가 유발되지 않아 발생 부위에 직접 적용할 수 있다. 또한 이 제제는 기존 정제의 부작용을 최소화하여 제품 생산이 가능하리라 생각한다. 이 제제에 스테로이드와 같은 다른 주요 성분을 첨가함으로써 구강으로 투여하는 방식보다 피부를 통해 투여할 수 있는 장점이 있어 활용도가 높을 것으로 사료된다. 또한 단독으로 사용해도 효과가 있다고 판단되어 의약품 제조 공정을 진행할 수 있을 것으로 기대된다.

연구배경: Acinetobacter baumannii는 항생제에 대한 내성균이 자주 발생하며 MDR Acinetobacter baumannii 감염의 치료 시 항생제 선택에 어려움이 있다. Colistin은 그람 음성균에 효과적이며 MDR Acinetobacter균에 감수성을 보이나 전신투여 시 신독성, 신경독성 등의 부작용으로 인해 잘 쓰이지 않는 약제이다. 전신투여에 의한 부작용을 회피하는 방법으로 분무치료가 있다. 그러나 MDR Acinetobacter baumannii 페렴환자에서 colistin 분무치료의 효과와 부작용에 대한 국내연구는 부족한 실정이어서 저자들은 다음과 같은 연구를 시행하였다. 방법: 2006년 12월부터 2007년 8월까지 중환자실의 폐렴환자 중에서 호흡기검체 배양검사를 통해 imipenem에 내성을 포함한 MDR Acinetobacter baumannii균에 의한 폐렴이 진단된 환자를 대상으로 하였다. 이들 중 항생제 정맥주사와 더불어 하루 3번의 colistin 분무치료를 시행했던 환자들의 의무기록을 후향적으로 분석하여 임상 소견, 신기능, 인공호흡기의 최대기도압의 변화를 분석 하였다 결과: 총 31명의 환자에서 colistin 분무치료를 시행하였다. Colistin 사용기간은 $14{\pm}7$일이었으며, 하루 흡입용량은 225~300 mg이었다. Colistin 분무치료 후 25명/31명(80.6%)에서 Acinetobacter균이 제거되었으나 이 중 11명(44%)에서는 2차 감염에 의한 새로운 균이 배양되었다. Colistin 분무치료 전, 후로 백혈구 수는 감소하였다. Colistin 분무치료 후 신기능의 장애는 발생하지 않았으며 의미 있는 기관지경련의 소견도 관찰되지 않았다. 결론: 적절한 항생제를 선택하기 어려운 MDR Acinetobacter baumanii에 의한 폐렴을 치료하는데 colistin 분무치료는 비교적 높은 균 제거율과 낮은 부작용을 보이므로 고려해 볼 수 있는 치료방법으로 사료된다.

Background: Gastric cancer (GC) is one of the most common cancers in China. Adjuvant chemotherapy (AC) is a routine auxiliary treatment for GC recommended by the guidelines issued in 2011 by the Ministry of Health of the People's Republic of China, but the relevant credible consequences in China have been insufficient because of China's late start and ethical concerns. Methods: A series of databases, including Cochrane Library, MEDLINE, EMBASE, the Chinese database of the National Knowledge Infrastructure and the VIP database, were searched by 2 reviewers independently for studies investigating AC for GC through March 2012. The retrieved literature was screened according to the eligibility criteria. Results: A total of 35 randomized control trials (RCTs) were subjected to the final analysis, including 4,043 patients in treatment group and 3,884 in the control group, as well as 4 clinical-control trials (CCTs), which accessed the final analysis with 238 and 252 patients, respectively. AC reduced the risk of death as a protective treatment with statistical significance (HR=0.91, 95%CI: [0.85, 0.97], P=0.002), and it seemed more effective for Asian than non-Asian patients. The effects of AC were not influenced by the starting time (P>0.05). D2 lymphadenectomy-based chemotherapy was effective (HR=0.89, 95%CI: [0.80, 0.99], P=0.04). Oral S-1 40 mg/m2 after D2 lymphadenectomy might be a better choice for Asians with advanced GC and might result in a greater reduction of adverse events than in non-Asian patients. GRADE quality assessment determined that the strength of the evidence from foreign studies from Europe, the United States and Asian countries other than China was high, while it was moderate for Chinese studies. Conclusion: AC was effective or even curative in Chinese patients in general, although it is still necessary to optimize a targeted AC scheme for Chinese patients with GC.

Background: The national Public-Private Mix (PPM) tuberculosis (TB) control project provides for the comprehensive management of TB patients at private hospitals in South Korea. Surveillance and monitoring of TB under the PPM project are essential toward achieving TB elimination goals. Methods: TB is a nationally notifiable disease in South Korea and is monitored using the surveillance system. The Korea Centers for Disease Control and Prevention quarterly generates monitoring indicators for TB management, used to evaluate activities of the PPM hospitals by the central steering committee of the national PPM TB control project. Based on the notification date, TB patients at PPM hospitals were enrolled in each quarter, forming a cohort, and followed up for at least 12 months to identify treatment outcomes. This report analyzed the dataset of cohorts the first quarter of 2016 through the fourth quarter of 2017. Results: The coverage of sputum, smear, and culture tests among the pulmonary TB cases were 92.8% and 91.5%, respectively. The percentage of positive sputum smear and culture test results were 30.7% and 61.5%, respectively. The coverage of drug susceptibility tests among the culture-confirmed cases was 92.8%. The treatment success rate among the smear-positive drug-susceptible cases was 83.2%. The coverage of latent TB infection treatment among the childhood TB contacts was significantly higher than that among the adult contacts (85.6% vs. 56.0%, p=0.001). Conclusion: This is the first official report to analyze monitoring indicators, describing the current status of the national PPM TB control project. To sustain its effect, strengthening the monitoring and evaluation systems is essential.

There are five principal causes for excessive bleeding in the immediate postextraction phase ; (1) Vascular wall alteration (wound infection, scurvy, chemicals, allergy) (2) Disorders of platelet function (genetic defect, drug-aspirin, autoimmune disease) (3) Thrombocytopenic purpuras (radiation, leukemia), (4) Inherited disorders of coagulation (hemophilia, Christmas disease, vitamin deficiency, anticoagulation drug-heparin, coumarin). If the hemorrhage from postextraction wound is unusually aggressive, and then dehydration and airway problem are occurred, the socket must be packed with gelatine sponge(Gelfoam) that was moistened with thrombin and wound closure & pressure dressing are applied. The thrombin clots fibrinogen to produce rapid hemostasis. Gelatine sponges moistened with thrombin provide effective coagulation of hemorrhage from small veins and capillaries. But, in dental alveoli, gelatine sponges may absorb oral microorganisms and cause alveolar osteitis (infection). This is a case report of bleeding control by continuous rubber strip & iodoform gauze drainage (without gelfoam packing) of active bleeding infection sites of three teeth extraction wounds in a 46-years-old female patient with advanced liver cirrhosis.

Purpose: The study investigated the effect of adolescent health behavior on the prevalence of current allergic diseases. Methods: The subjects were 57,303 middle and high school youth. Data were analyzed using Rao-Scott χ² test and complex sample logistic regression analysis. Results: While controlling the affect of the general characteristics of the subjects, health behaviors affecting the current prevalence of allergic diseases were smoking, drinking, physical activity, eating habits, drug abuse, and mental health. Smoking behaviors affecting the current prevalence of allergic diseases were lifetime smoking experience, smoking days, liquid e-cigarette lifetime smoking experience, number of liquid electronic cigarette smoking days, e-cigarette lifetime smoking experience, e-cigarette smoking days, amount of smoking, second-hand smoking and drinking behaviors were lifetime drinking, drinking days, the amount of drinking, and severe drinking. Variables such as physical activity exceeding 60 minutes days, intake of energy and sweet drinks, water intake, habitual drug use and mental health behavior such as stress perception, weekday sleep time, subjective sleep satisfaction, depression, suicidal thoughts/ plan/ attempts affect current allergic diseases (p<.001). Conclusion: The results showed that current allergic disease related health behaviors in Korean adolescents. Therefore, considering these factors, it may be helpful to facilitate a health promotion plan for prevention and management of such diseases and to promote evidence-based health practices at school.

The purpose of this study was to call attention to the mental, physical and occupational hazards of the anticancer-drug-handling nurses by examining the possible urinary mutagenicity and measuring physical symptoms and stress level of the nurses exposed to anticancer drugs. The experimental group of the urinary mutagenicity assay was 14 nurses handling anticancer drugs at the medical wards of a hospital located in J city ; the control group was 12 psychiatric nurses of the same hospital. The test material was the nurses' 24hrs urine, which was concentrated by XAD-2 column chromatography. Tester strains were TA98(±S9 mix), TA100(±S9 mix), TA1535(±S9 mix) and TA1537(±S9 mix) ; Salmonella mammalian-microsomal test(Ames test) was employed for the urinary mutagenicity assay. The physical symptoms of which the nurses experienced were investigated through self-reports on open-questionnaires. The stress levels of the experimental group were measured by a stress measuring instrument developed by this author. Reliability of this instrument was found to be adequate (Cronbach's Alpha=0.9079). To ascertain the urinary mutagenicity of the experimental group, the mean and the standard deviation of the colonies of Tester strains appearing on the minimal plates were taken and compared differences between two groups. T-test was employed for the significance test of two groups. The physical symptoms were compared between the two groups through the analysis of the nurse' self-reports. The mean and standard deviation of the stress levels of the experimental group were also calculated and were examined through t-test. The results were summarized as follows : 1. The experimental group revealed significantly higher urinary mutagenicity both in the activation method test and the non-activation method test of the tester strains TA98, TA100 and TA1535. In the case of TA1537, two groups showed no difference in the non-activation method test, but the activation method revealed difference. 2. The physical symptoms were also much more frequently reported in the experimental group. 79.3% of the experimental group reported more than 1 kind of physical symptoms. On the other hand, 33.2% of the control group complained of 1 kind of physical symptom. The items with high symptom frequency were 'headache', 'itching sensation', 'corneal congestion', 'skin allergy' 3. The mean score of stress in the experimental group was 2.41(range 1-4). The experimental group showed the stress level above 2.0 in the 14 of 15 items in all. The highest stress level were recorded in the following items in the order quoted, 'I fear that anticancer drug may touch any part of body while handling it.', 'I feel concerned there is no protective countermeasure against anticancer drug handling.', 'I am afraid the anticancer drug handling may produce a fetal loss in the future'.

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.
