Objective : Herb-drug interactions have become an important issue because of the consumption of herbal remedies has increased in the world. Yangguksanhaw-tang (Liang ge san huo-tang) and Taeumjowi-tang (Tai yin tiao wei-tang) are typical herbal formulas on Sasang constitution medicine (four-constitution medicine). This study was aimed at evaluating the effects of Yangguksanhaw-tang and Taeumjowi-tang on drug metabolizing enzymes, cytochrome P450 (CYP450) isozymes. Methods : Vivid$^{(R)}$ CYP450 Screening Kits were used to measure of CYP3A4, CYP2C19, CYP2D6 and CYP2E1 activities. This method is based on the use of fluorescent CYP450 substrates that are efficiently metabolized by specific CYP450 isozymes to yield a product with altered fluorescent properties. The percent inhibitions of CYP450s by herbal formulas were calculated. Results : Yangguksanhaw-tang inhibited CYP2C19 and CYP2E1 activities higher than that other CYP450 isozymes. The $IC_{50}$ values of CYP2C19 and CYP2E1 were 159.83 ${\mu}g/mL$ and 261.40 ${\mu}g/mL$, respectively. The CYP2E1 activity was inhibited ($IC_{50}=215.17{\mu}g/mL$) higher than that other CYP450 isozymes by Taeumjowi-tang. Conclusions : These results suggest that Yangguksanhaw-tang may inhibit the metabolism of co-administered drugs whose primary route of metabolism is via CYP2C19 or CYP2E1. Taeumjowi-tang could inhibit the metabolism of co-administered drugs, which are substrates for CYP2E1. Therefore, co-administration of the herbal formulas and other conventional drugs should be undertaken with care.

Objectives: The goal of this study was to perform an economic analysis of a primary stenting with drug-eluting stents (DES) compared with bare-metal stents (BMS) in patients with acute myocardial infarction (AMI) admitted through an emergency room (ER) visit in Korea using population-based data. Methods: We employed a cost-minimization method using a decision analytic model with a two-year time period. Model probabilities and costs were obtained from a published systematic review and population-based data from which a retrospective database analysis of the national reimbursement database of Health Insurance Review and Assessment covering 2006 through 2010 was performed. Uncertainty was evaluated using one-way sensitivity analyses and probabilistic sensitivity analyses. Results: Among 513 979 cases with AMI during 2007 and 2008, 24 742 cases underwent stenting procedures and 20 320 patients admitted through an ER visit with primary stenting were identified in the base model. The transition probabilities of DES-to-DES, DES-to-BMS, DES-to-coronary artery bypass graft, and DES-to-balloon were 59.7%, 0.6%, 4.3%, and 35.3%, respectively, among these patients. The average two-year costs of DES and BMS in 2011 Korean won were 11 065 528 won/person and 9 647 647 won/person, respectively. DES resulted in higher costs than BMS by 1 417 882 won/person. The model was highly sensitive to the probability and costs of having no revascularization. Conclusions: Primary stenting with BMS for AMI with an ER visit was shown to be a cost-saving procedure compared with DES in Korea. Caution is needed when applying this finding to patients with a higher level of severity in health status.

Objectives: This study provides insights on the impact of a targeted intervention (TI) programme on behaviour change among injecting drug users (IDUs) in India. Methods: This paper examined the data from the Integrated Biological and Behavioural Surveillance 2014-2015 for IDUs in India. Logistic regression was performed to understand the factors (TI programme services) that affected injecting risk behaviours by adjusting for covariates. Propensity score matching was conducted to understand the impact of the TI programme on using new needles/syringes and sharing needles/syringes in the most recent injecting episode by accounting for the covariates that predicted receiving the intervention. Results: Participants who received new needles and syringes from peer educators or outreach workers were 1.3 times (adjusted odds ratio, 1.29; 95% confidence interval [CI], 1.09 to 1.53) more likely to use new needles/syringes during most recent injecting episode than participants who did not receive needles/syringes. The matched-samples estimate (i.e., average treatment effect on treated) of using new needles in the most recent injecting episode showed a 2.8% (95% CI, 0.0 to 5.6) increase in the use of new needles and a 6.5% (95% CI, -9.7 to -3.3) decrease in needle sharing in the most recent injecting episode in participants who received new needles/syringes. There was a 2.2% (95% CI, -3.8 to -0.6) decrease in needle sharing in the most recent injecting episode among participants who were referred to other services (integrated counselling and testing centre, detox centres, etc.). Conclusions: The TI programme proved to be effective for behaviour change among IDUs, as substantiated by the use of new needles/syringes and sharing of needles/syringes.

The purpose of this study is to analyze the side effects (ADR) of Traditional Chinese Medicine (TCM) injections by age, injection type, symptoms, and causes, and to find preventive solutions for ADR. For the ADR of TCM injection data collected during the search period from January 1, 2010 to December 31, 2020, the correlation between each section was analyzed by subdividing it into age, injection type, symptoms and causes. CNKI, PubMed, and EMBASE were used to collect the clinical data. 'Chinese herbal injection', 'Traditional Chinese Medicine injection', 'Chinese herbal injection side effect', 'Chinese herbal injection adverse drug reaction' were used for the keyword from the database. All data were collected mainly for TCM injection and the causes of ADR due to TCM injection. However, data not related to the relevant study or TCM injection were excluded from this study. Among a total of 941 studies collected during the search period from January 1, 2010 to December 31, 2020, a total of 10 studies were selected for final analysis. In 1462 clinical data sets, ADR by gender was higher in males than females. By age, 41 to 60 years were the most common. The incidence of ADR by injection type was highest in the blood regulating injection type. Data analysis showed Xueshuantong injection had the highest ADR. Among the symptoms of ADR, skin diseases were the most common. The most common cause of ADR was the unreasonable use of drugs. In China, for ADR management, the use of TCM injections is recommended according to the basic principles for the clinical use of TCM injections established by the Chinese government. In this study, we analyzed the current status and causes of ADR in TCM injections, and found a preventive solution. It is expected that it can be used as basic data to increase the usability of pharmacopuncture and herbal medicines in Korea in the future.

The global crisis caused by the coronavirus disease 2019 (COVID-19) led to the most significant economic loss and human deaths after World War II. The pathogen causing this disease is a novel virus called the severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). As of December 2020, there have been 80.2 million confirmed patients, and the mortality rate is known as 2.16% globally. A strategy to protect a host from SARS-CoV-2 is by suppressing intracellular viral replication or preventing viral entry. We focused on the spike glycoprotein that is responsible for the entry of SARS-CoV-2 into the host cell. Recently, the US Food and Drug Administration/EU Medicines Agency authorized a vaccine and antibody to treat COVID-19 patients by emergency use approval in the absence of long-term clinical trials. Both commercial and academic efforts to develop preventive and therapeutic agents continue all over the world. In this review, we present a perspective on current reports about the spike glycoprotein of SARS-CoV-2 as a therapeutic target.

1989년 10월부터 실시되고 있는 약국의료보험과 의약분업제도에 관한 태도를 조사하기 위하여 대구시내 개원의사 및 재국약사를 계통적 표본추출법(systematic sampling)에 의한 표본을 선정하여 우편설문지법으로 1992년 4월 20일부터 5월 20일까지 조사하여 회신된 개원의사 184명, 개국약사 157명의 설문지를 분석한 결과를 요약하면 다음과 같다. 현재 시행중인 약국의료보험의 성과에 대해 개원의사는 71.2%가 '실패적'이라고 한 반면 개원약사는 13.4%가 '실패적'이라고 하였다. 개원의사의 50%는 약국의료보험을 폐지하고 의약분업을 도입해야 한다고 한 반면, 개국약사는 66.9%가 의약분업제도와는 관계없이 약국의료보험자체만으로도 성공적인 제도라고 하였다. 개국약사의 약국 1일 평균조제건수는 32.2회였으며, 약국의료보험 이용횟수는 6.2회로 조제건수의 20%에 불과했고, 의사처방전을 지참한 약국의료보험이용횟수는 조제건수의 0.7%였다. 그리고 개원의사의 원외처방전 발행경험자는 58.7%였다. 의약분업제도의 실시에 대해 개원의사는 59.2%가 찬성하였으며 27.7%가 반대하였으나 재국약사는 38.0%가 찬성, 45.5%가 반대 하였다. 그리고 약사가 의사보다 의약분업의 내용을 더 많이 안다고 하였다. 의약분업제도 실시의 찬성자중 찬성이유로 개원의사는 '의약품의 남오용 방지' (54.1%)를 많이 지적한 반면 개국약사는 '의사와 약사의 전문직능 발휘'(62.0%)를 많이 제기하였다. 그리고 분업찬성자에서 개원의사는 52.3%가 '완전강제분업'을 원한 반면, 개국약사는 81.7%가 '부분분업'을 원하였다. 의약분업제도 실시시에 처방전의 발행 방법에 대해서는 개원의사와 개국약사 모두 '일반명' 처방을 44.0%, 89.8%로 가장 많이 원하였고 개원의사에서는 '상품명' 처방도 35.3%나 차지하였다. 의약분업제도의 실시가 이루어지지 않은 이유에 대해 개원의사 및 개국약사 모두 '의사 약사단체 상호간의 업권문제'를 가장 많이 지적했으며 '국민들의 인식 및 관심 부족' '정부의 의지력 결여' 순으로 일치된 결과로 나타났다. 의약분업실시를 위한 선결조건으로는 '의료시설과 약국의 도시 농촌간의 균등분포'를 가장 많이 지적하였으며 의사는 '약사들의 수용태세 확립', 약사는 '의사의 수용태세 확립'을 그 다음으로 지적해 서로 상반된 결과가 나타났다. 이상의 결과를 종합해 보면 첫째, 조사대상 개원의사들은 현행 약국의료보험제도에 대해 부정적 견해를 보인 반면 개국약사들은 긍정적 견해를 보였으나 약국의료보험이용은 극히 저조하고 의사의 처방전 발행도 저조한 실정이다. 이에 약국의료보험제도에서 의약분업제도로의 제도적 전환이 고려되어야 할 것으로 생각된다. 둘째, 의사와 약사의 의약분업에 대한 의견이 상이한 점으로 미루어 유추할 수 있지만 의약분업제도 실시의 장애요인으로 의 약사단체 상호간의 업권문제와 의약사간의 갈등이 지적되는 바, 이들 모두를 만족 할 대안을 선택하는 것이 쉬운일 아닐 것이므로 국민의 건강보호차원에서 정부의 중립적 의지가 있어야 할 것으로 생각된다.

Objective : There are many documents that explain efficacy of herbal medicine products (HMP), however, explanations on efficacy are not consistent with the clinical use. The objective of this study is to identify the differences between herbal medicines used in clinics and Korean Medicine literatures. The disease was restricted in low back pain (LBP). Method : In order to investigate HMP for the treatment of LBP, we selected five Korean medical documents as reference and searched for key words related to LBP. Five databases were Information on Herbal prescription published by Ministry of Food and Drug Safety, 56 Herbal Medicines covered with Health Insurance, Guideline for prescribing herbal medicines announced by Ministry Health & Welfare, Explanation on Herbal Medicines published by Korean Pharmaceutical Association, website of Korea Pharmaceutical Information Center (http://www.health.kr/). The keywords were 'low back pain', 'lumbar', 'pain', 'myalgia', 'neuralgia', 'arthralgia', 'arthroneuralgia', and 'sciatica'. We also utilized the result of retrospective cross-sectional study in five university hospitals to investigate HMP used in practice for LBP. Results : From five databases, the number of searched HMP was 25, 12, 40, 12 and 38 respectively and 83 remained after removing duplications. There were 43 kinds of HMP used in clinical practice and only 20 (46.51 %) were included in one or more databases. Conclusion : This study suggests the necessity for reorganizing efficacy of herbal medicine. Standardizing explanation on herbal medicine should reflect the clinical conditions in further study.

This study aimed at determining the current knowledge, attitude, and practices (KAP) of layer and pig farmers to antimicrobial usage and its consequences. Description of such KAP could provide insights useful for promoting the rational use of antimicrobials in livestock. From May 2014 to February 2016, a survey involving 251 respondents in Chiang Mai, Lamphun, and Chonburi provinces, Thailand, was conducted by using a validated questionnaire. More than half (51.0%) of the respondents incorrectly believed that antimicrobial drug efficacy could not be reduced by using sub-recommended dosages, 61.2% had misconceptions about non-therapeutic antimicrobial use, and 66.9% inaccurately felt that antimicrobials were also effective for virus and fungi. Over half (50.6-55.2%) did not see the need to follow instructions or advice of veterinarians. Moreover, only 10.4% regularly relied on responses to drugs sensitivity tests when evaluating the effectiveness of antimicrobials. Overall, assessment of KAP regarding antimicrobial usage indicated that the majority of respondents had low levels of knowledge of antimicrobials, neutral rather than positive attitudes, and employed poor practices in the use of antimicrobials. The results indicate improvements in KAP could be helpful in developing more effective interventions by farmers, reduce antibiotic usage, and slow the growth of antimicrobial resistance.

In this study, the quick HPLC-MS/MS method for the simultaneous separation of 2-acetyl-4(5)-tetrahydroxybuthylimidazole (THI) and 4-(5)-methylimidazole (4-MI) in alkaline medium was used for caramel color and processed foods in Korea. After a simple sample pretreatment, 51 4-MI-labeled samples were positive for 4-MI and 2 also contained THI. The concentration of 4-MI was 260.5~24, $499.3{\mu}g/kg$ in caramel color, less than $LOD{\sim}1,712.5{\mu}g/kg$ in sauce, 1,242.3, $5,972.2{\mu}g/kg$ in balsamic vinegar, $2,118.3{\sim}5,802.4{\mu}g/kg$ in complex seasoning, $82.7{\sim}5,110.6{\mu}g/kg$ in curry, and $29.9{\sim}464.4{\mu}g/kg$ in soft drinks. The recovery rate of 4-MI was 97.1~111.0% in sauce and 81.9~110.0% in powder and that of THI was 83.6{\sim}106.4% in sauce and 61.2{\sim}99.4% in powder. Our results concluded a safe amount of 4-MI and THI compared to the limit of Korea additive code but the processed foods do not have a limit of caramel color and 4-MI in Korea. Therefore, research and monitoring of 4-MI and THI is needed for processed foods in Korea.
