Objectives This study aimed to analyze the research trends in clinical studies on the traditional Korean medicine used for cancer treatment between 2011 and 2020. Methods We searched 7 Korean web databases (Research Information Sharing Service [RISS], Oriental Medicine Advanced Searching Integrated System [OASIS], Koreanstudies Information Service System [KISS], Korean Medical database [KMBASE], DBpia, Korea Institute of Science and Technology Information [KISTI], and KoreaMed) and classified collected papers dated between 2011 and 2020 by the year of publication, publication journal, study design, type of cancer affecting the patients, interventions used, evaluation system used, and combination with conventional medicine. Results A total of 167 papers were collected. More than 10 papers were published annually. The papers were mainly published in the Journal of Korean Traditional Oncology (28.7%). The predominant type of the study was case study (67.7%). The main type of cancer was breast cancer, affecting 262 patients. Most of the studies reported using multiple traditional Korean medicine treatments (55.1%). Eighty-nine studies reported using clinical laboratory tests for evaluation. Most of the patients took conventional medicine simultaneously (608 patients). Conclusions Research related to Korean medicine for cancer patients is at a rudimentary level. Therefore, for further clarity, high evidence-based researches, including randomized controlled trials and cohort studies, should be conducted.

The inflammatory myopathies are divided into three major and distinct subsets as polymyositis(PM), dermatomyositis(DM), and inclusion body myositis(IBM). This distinction is based on unique clinical, demographic, laboratory, histologic, therapeutic, prognostic, and immunopathologic criteria. Although the causes of PM, DM, and IBM are unknown, autoimmune mechanisms are implicated, as supported by their association with other putative or definite autoimmune diseases or viruses, the evidence for a T cell-mediated myocytotoxicity or complement-mediated microangiopathy, the presence of various autoantibodies and their response to immunotherapies. But in IBM the immune-mediated process is weaker and IBM patients do not readily respond to immunotherapies, there are convincing immunopathological signs to suggest that a definite autoimmune component, similar to that seen in PM, also plays a role in the cause of IBM.

The objectives of this study are to examine the current status and problems of herb-drug interaction (HDI) information and information database in Korea and suggest the better way to establish useful HDI database. We collected HDI studies that published in Korea and analyzed according to objective, methods, selection criteria of herbs, number of study, correlation between study subject and frequently used herbal medicine (HM). Then we selected representative HM database on the internet made by Korea Food and Drug Administration (KFDA) among the several databases and analyzed its contents related to HDI. Several HDI studies were carried out from laboratory based research to clinical trials and HM databases have been developed for providing information about different aspects of traditional Korean medicine. But the information of HDI and information database are still far from practical applications because there are no coherence to select study subjects and methods among researchers. So, it is necessary to build up HDI database led by the government for providing systematic HDI information. HDI information database is expected to be able to provide useful evidence for health professionals in prescription and consultation to reduce the chance of adverse effects and improve the quality of medical care.

Current educational interventions and training courses in microsurgery are often predicated on theories of skill acquisition and development that follow a 'practice makes perfect' model. Given the changing landscape of surgical training and advances in educational theories related to skill development, research is needed to assess current training tools in microsurgery education and devise alternative methods that would enhance training. Simulation is an increasingly important tool for educators because, whilst facilitating improved technical proficiency, it provides a way to reduce risks to both trainees and patients. The International Microsurgery Simulation Society has been founded in 2012 in order to consolidate the global effort in promoting excellence in microsurgical training. The society's aim to achieve standarisation of microsurgical training worldwide could be realised through the development of evidence based educational interventions and sharing best practices.

A 9-month-old, intact female mixed dog was referred to Veterinary Medical Teaching Hospital of Gyeongsang National University with symmetrically enlarged and protruded upper jaw. The patient was diagnosed as acute renal failure due to ethylene glycol poisoning and was treated for 1 month in a local animal hospital. In spite of treatment, the patient proceeded to chronic renal failure. Also, the patient's upper jaw begun to enlarge continuously. To evaluate this upper jaw, radiographic examination was performed. Skull radiographs revealed thickening of maxilla, decreased bone opacity, cortical thinning, loss of lamina dura and periodontal space in the maxilla. Diagnosis of rubber jaw syndrome is based on clinicial signs, radiographic findings and laboratory evidence of chronic renal failure due to ethylene glycol poisoning.

There are conflicting views for the polymerization process of human UDP-glucose dehydrogenase (UGDH) and no clear evidence has been reported yet. Based on crystal coordinates for Streptococcus pyogenes UGDH, we made double mutant A222Q/S233G. The double mutagenesis had no effects on expression, stability, and secondary structure. Interestingly, A222Q/S233G was a dimeric form and showed an UGDH activity, although it showed increased $K_m$ values for substrates. These results suggest that Ala222 and Ser233 play an important role in maintaining the hexameric structure and the reduced binding affinities for substrates are attributable to its altered subunit communication although quaternary structure may not be critical for catalysis.

Purpose: The objective of this prospective study was to evaluate the relationship between the circulating lymphocyte subpopulation counts during preoperative chemoradiotherapy (CRT) and tumor response in locally advanced rectal cancer. Materials and Methods: From August 2015 to June 2016, 10 patients treated with preoperative CRT followed by surgery were enrolled. Patients received conventional fractionated radiotherapy (50.4 Gy) with fluorouracil-based chemotherapy. Surgical resection was performed at 4 to 8 weeks after the completion of preoperative CRT. The absolute blood lymphocyte subpopulation was obtained prior to and after 4 weeks of CRT. We analyzed the association between a tumor response and change in the lymphocyte subpopulation during CRT. Results: Among 10 patients, 2 (20%) had evidence of pathologic complete response. In 8 patients with clinically node positive, 4 (50%) had nodal tumor response. All lymphocyte subpopulation counts at 4 weeks after CRT were significantly lower than those observed during pretreatment (p < 0.01). A high decrease in natural killer (NK) cell, count during CRT (baseline cell count - cell count at 4 weeks) was associated with node down staging (p = 0.034). Conclusion: Our results suggest that the change of lymphocyte subset to preoperative CRT may be a predictive factor for tumor response in rectal cancer.

Objectives: Radix Ginseng has been traditionally used as an adaptogen that acts on the adrenal cortex and stimulates or relaxes the nervous system to restore emotional and physical balance and to improve well-being in cases of degenerative disease and/or old age. Radix Ginseng has been used for a long time, but the safety of ginseng pharmacopuncture needs testing. This study was done to analyze the single-dose toxicity of water- soluble ginseng pharmacopuncture (GP) intramuscular injections in rats. Methods: All experiments were performed at Biotoxtech, an institution authorized to perform non clinical studies under the regulations of Good Laboratory Practice (GLP). Each group contained 10 Sprague-Dawley rats, 5 males and 5 females. GP was prepared in a sterile room at the Korean Pharmacopuncture Institute under regulations of Good Manufacturing Practice (GMP). GP dosages were 0.1, 0.5 and 1.0 mL for the experimental groups; normal saline was administered to the control group. The animals general condition was examined daily for 14 days, and the rats were weighed on the starting day and at 3, 7 and 14 days after administration of the pharmacopuncture. Hematological and biochemistry tests and autopsies were done to test the toxicological effect of GP after 14 days. This study was performed with approval from the Institutional Animal Ethics Committee of Biotextech. Results: No deaths were found in this single-dose toxicity test of intramuscular injections of GP, and no significant changes in the general conditions, body weights, hematological and biochemistry tests, and autopsies were observed. The local injection site showed no changes. Based on these results, the lethal dose was assumed to be over 1.0 mL/animal in both sexes. Conclusion: These results suggest that GP is relatively safe. Further studies, including a repeated toxicity test, are needed to provide more concrete evidence for the safety of GP.

Objective : In order to understand the changes in domestic approval regulations applicable to traditional Korean medical device companies, this article will explain the major amendments 「Regulation on Medical Device Approval Report Review, etc.」 from 2005 to the present on a year-by-year basis, and provide a counter plan to the recent changes in approval regulations. Methods : We analysed the changes in approval regulatory amendments related to the traditional Korean medical devices from 2005 to the present. Results : The Ministry of Food and Drug Safety is continuously improving medical device approval regulations to ensure the global competitiveness of domestic medical devices and contribute to the improvement of public health. Recent major approval regulatory amendments include the establishment of a review system for software medical devices and digital therapeutics, the recognition of real world evidence materials, the introduction of a biological evaluation of medical devices within a risk management process and a medical device approval licence renewal system. Conclusions : It is expected that the range of medical devices available to Korean medicine doctors will continue to expand in the future through the provision of non-face-to-face medical services and the development of advanced and new medical devices, as well as wearable medical devices and digital therapeutics. In order to increase the market entry potential of traditional Korean medical devices that incorporate advanced technologies such as digital technology and AI-based diagnosis and prediction technology, it is urgent that the government provide significant support to traditional Korean medical device companies to improve approval regulatory compliance.
