In this study, we examine the changes to Korean medicine that occurred when 'proprietary medicines' (賣藥) swept through the pharmaceutical market during the Japanese occupation (1910-1945 C.E.). Proprietary medicine during the Japanese colonial period took various forms including ready-made, over-the-counter, patent, and nostrum type pharmaceuticals. This paper examines how Korean medicine, which was the dominant form of medicine during the Joseon Dynasty, was forced to adapt to the rise of proprietary medicines. We found that the prescription of Korean medicine herbal decoctions became more like proprietary medicine in the way that they were formulated. In addition, prescriptions in Korean medicine books were reformulated with prescriptions and medicines from outside the tradition. Proprietary medicines, many of which were made with secret recipes handed down in a family, also attracted attention. Such prescriptions were made famous through advertisements and further influenced future Korean medicine doctors. New prescriptions took advantage of the trust and authority existing in traditional Korean medicine by introducing ginseng and traditional medicinal herbs such as deer antler velvet (鹿茸, Cervi Parvum Cornu). This paper argues that proprietary medicine of the Japanese colonial period distorted the concept of traditional herbal medicine.

Objectives : The Dong-hwa Yakbang Cheobangcheol, a formulary on proprietary medicines created by Dong-hwa Pharmacy in the early 20th century was analyzed with a focus on characteristics of the formulas that were made and sold at the time. Methods : First, external features such as bibliography, table of contents, and descriptive style were examined. In content, licensure of listed formulas, ingredients, dosage form, manufacturing process, effects, properties were medically and pharmacologically analyzed. In this process, the Japanese Pharmacopeial Convention, legislation related to medicinal pharmacology during Japanese Colonial Period, and the Donguibogam were referenced. Results : In terms of form, the Dong-hwa Yakbang Cheobangcheol faithfully follows medicinal related legislation established in the Japanese Colonial Period. However, in terms of content, we could see that most of the formulas were based on the Korean Medical tradition, while Western pharmaceutical technology and chemicals were selectively integrated when necessary. Conclusions : The Dong-hwa Yakbang Cheobangcheol comprehensively displays the situation and goal of Dong-hwa Pharmacy, one of the most representative pharmaceutical companies in proprietary medicine of the early 20th century, in which it was under pressure to adapt to power for survival, while it strived to help improve the health of the people of the time by adopting strengths of both Eastern and Western medicinals.

A mixture of several bacterial metabolites $(Sterodin{\circledR})$ was used to study its effect on major immunocytes, in vivo and in vitro. This mixture of bacterial metabolites increased number of macrophages and neutrophils and their phagocytic activity in experimental animals for a transient period. BSA induced antibody production was found to be higher in the drug treated group. These results indicated that the bacterial metabolites probably acted through non-specific defence mechanism against invading organisms and the chance of reinfection was reduced.

Objectives: This study presents Korean medicine clinical practice guidelines for bladder cancer, of which the 5-year survival rate has still been about 75% since the 1990s despite the rapid development of medical science. Methods: A consensus was reached by an expert committee composed of professors and researchers who specialize in Korean medicine on the basis of a literature review that included other countries' clinical guidelines and a textbook. Results: Traditional Chinese medicine clinical practice guidelines were published for the first time in 2014. In Korea, the medical system is different from China in that Korea has completely dualized Korean and Western medicine and a low availability of proprietary herbal medicines. Therefore, these Korean medicine clinical practice guidelines for treating bladder cancer based on the previously published guidelines of Chinese medicine will help first-line Korean medicine doctors. Conclusions: Further studies related to Korean medicine are necessary to develop more advanced Korean medicine clinical practice guidelines for treating bladder cancer.

Zoletil is a non-opioid, non-barbiturate animal anesthetic and proprietary combination of two drugs, a dissociative anesthetic drug, tiletamine, with the benzodiazepine anxiolytic drug, zolazepam. Zoletil has greater potency than ketamine. Zoletil is abused for recreational purposes, especially by people with easy access to medicine. However, in Korea, it is available over-the-counter. Here we report on a case of an 83-year-old woman who received injection of seven vials of "Zoletil 50" by her daughter and presented with an altered mental change. Her mental state was stupor and vital sign was hypotension, bradycardia. Her blood tests indicated metabolic and respiratory acidosis and hyperkalemia. She was treated with intravenous naloxone and flumazenil but was not responsive. She was admitted to the ICU and treated with supportive therapy. Her mental state showed transient recovery, however, her clinical manifestation worsened and she expired.

BACKGROUND: Assessment of left ventricular (LV) function plays a pivotal role in the management of patients with valvular heart disease, including those caused by rheumatic heart disease. Noninvasive LV pressure-strain loop analysis is emerging as a new echocardiographic method to evaluate global LV systolic function, integrating longitudinal strain by speckle-tracking analysis and noninvasively measured blood pressure to estimate myocardial work. The aim of this study was to characterize global LV myocardial work efficiency in patients with severe rheumatic mitral stenosis (MS) with preserved ejection fraction (EF). METHODS: We retrospectively included adult patients with severe rheumatic MS with preserved EF (> 50%) and sinus rhythm. Healthy individuals without structural heart disease were included as a control group. Global LV myocardial work efficiency was estimated with a proprietary algorithm from speckle-tracking strain analyses, as well as noninvasive blood pressure measurements. RESULTS: A total of 45 individuals with isolated severe rheumatic MS with sinus rhythm and 45 healthy individuals were included. In healthy individuals without structural heart disease, the mean global LV myocardial work efficiency was 96% (standard deviation [SD], 2), Compared with healthy individuals, median global LV myocardial work efficiency was significantly worse in MS patients (89%; SD, 4; p < 0.001) although the LVEF was similar. CONCLUSIONS: Individuals with isolated severe rheumatic MS and preserved EF, had global LV myocardial work efficiencies lower than normal controls.

A Softgel is an oral dosage form for medicine similar to capsules and softgel dosage form offers several advantages over other oral dosage forms, such as delivering a liquid matrix designed to solubilize and improve the oral bioavailability of a poorly soluble compound as a unit dose solid dosage form, delivering low and ultra-low doses of a compound. This study aimed to qualify a proprietary vegetable soft capsule which contains modified starch and carrageenan as capsule shell components compare to the conventional gelatin softgel. Four kinds of samples were prepared with vegetable and gelatin capsule shell, respectively. Morphology of capsule shell, mechanical strength of capsule, and hygroscopic properties were studied for comparing the quality attributes of softgel. Short-term stability against heat and moisture was also investigated in this study. Vegetable capsule shell showed better mechanical strength, physical stability and disintegration time for temperature and humidity than those of conventional gelatin capsule shell with four different filling materials used frequently as soft capsule form. Conclusively, this vegetable capsule shell polymer system can replace easily gelatin-shell systems and additionally allows encapsulation of lipid fills at high temperatures that are semisolid or solid-like at room temperature.

양전자 방출 단층촬영에서 정량적 평가에 통상적으로 쓰이는 표준섭취계수(SUV : Standardized Uptake Value)는 종양의 병소와 병기의 진단 그리고 치료 성적 평가에 있어서 사용되고 있는 유용한 지표이다. 하지만 SUV는 환자의 체격, 검사까지의 시간, 부분용적 효과, 관심영역의 설정, 검사장비, 영상재구성 차이 등에 따라 변화 되므로 다양한 인자의 영향을 고려하여야만 한다. 그 중에서도 PET/CT 장비와 영상의 재구성 방법의 차이에 의한 SUV의 차이를 SIEMENS 사의 EQ PET을 이용하여 방사능의 차이를 보정 할 수 있게 되었다. 그러므로 본 연구에서는 phantom 실험과 FDG PET 임상영상의 SUVmax를 비교 하여 EQ PET을 적용함으로써, SUV의 변화를 평가 하고 EQ PET의 유용성에 대해서 검증해보고자 하였다. 본원의 3대의 PET/CT 장비인 Biograph true point 40, Biograph mCT 40, Biograph mCT 64 장비를 이용하여 $^{18}F-FDG$를 주입 한 NEMA IEC body phantom 영상을 획득 한 후 OSEM3D+PSF, OSEM3D+TOF, OSEM3D+PSF+TOF의 알고리즘을 이용하여 영상을 재구성 하였다. 각각 재구성된 영상에서 관심영역의 방사능 농도를 측정한 후, EARL에서 권고하는 NEMA IEC body phantom의 방사능 농도의 회복계수 값을 비교하여 서로 다른 PET system 간에 방사능 농도의 차이를 줄일 수 있는 EQ filter 값을 산출 하였다. 산출한 EQ Filter 값을 장비와 영상 재구성에 따라 적용하여 팬텀의 회복계수와 61명의 폐암환자의 FDG PET 영상에서 종양의 SUVmax를 비교 분석 하였다. 3대의 PET/CT 장비에서 영상의 재구성 알고리즘을 달리하여 획득한 phantom의 영상의 6개구의 평균 변동계수는 EQ PET 적용 전 후의 값은 OSEM3D 재구성 영상에서 각각 0.05, 0.04 OSEM3D+TOF 재구성 영상에서는 각각 0.04, 0.03, OSEM3D+PSF 재구성 영상에서는 각각 0.04, 0.03, OSEM3D+PSF+TOF 재구성 영상에서는 각각 0.03, 0.02 값을 보여 EQ PET 적용 후 팬텀의 6개 구의 평균 변동계수는 감소하였다. 임상 영상 비교 에서는 폐암환자 종양의 SUVmax는 OSEM3D, OSEM3D+TOF, OSEM3D+PSF, OSEM3D+PSF+TOF 순으로 증가하였으며, EQ PET 적용 후 재구성 영상에 대한 SUVmax는 통계적으로 유의한 차이가 없었다(p=1.000). PET/CT 영상에서 서로 다른 PET/CT 장비와 영상의 재구성 방법의 차이에 의해 발생하는 방사능 농도의 차이를 EQ PET을 이용하여 측정함으로서 장비와 영상 재구성별 방사능 농도의 편차가 감소되었다. PET 영상에서 정량적 평가에 이용되는 SUV의 편차를 줄일 수 있어 종양의 병소와 병기의 진단, 그리고 치료 성적평가의 정량적 평가 신뢰도가 향상 될 것으로 사료된다.

Purpose : Energy bars are increasingly popular among active individuals, yet their timing and nutrient combinations' impact on exercise adaptation remains unclear. This study aims to address this knowledge gap by investigating whether the combination of pre- and post-workout supplementation can synergistically enhance fitness and alleviate fatigue in trained CrossFit participants. Investigate if combining pre- and post-workout supplements can enhance fitness and blood lactate management in trained CrossFit participants, potentially improving exercise performance for this group. Methods : In a randomized crossover study, 20 trained CrossFit individuals (11 males, 9 females) completed thrice-weekly 60-minute CrossFit sessions for 3 weeks, with a one-week washout period. Participants were randomly assigned to either a chocolate bar group (CH, 45 g, 225 kcal) or an energy bar group (ES, 48 g, 238 kcal, with protein, caffeine, taurine, and BCAAs). For one week, participants consumed two bars of their assigned supplement five minutes before and after workouts. After a washout period, they switched supplements. Blood lactate levels and a visual analog scale (VAS) were assessed before, immediately after, and 30 minutes post-workout. Fitness tests (hand grip, broad jump, sit-ups) were conducted at baseline and 30 minutes post-final workout. Data were analyzed using two-way repeated measures ANOVA (p<.05), 95 % confidence intervals, and magnitude inferences. Results : Hand grip strength (t=-5.60, p=.000), broad jump (t=-3.43, p=.003) and sit up (t=-3.94, p=.001) were significantly increased in the ES group. Compared to CH group, there was a significant time and group interactions for blood lactate level (F=5.51, p=.008) and VAS(F=31.67, p=.000) in the ES group. Conclusion : Pre- and post-workout energy bar supplementation may have a beneficial effect on blood lactate clearance and fitness in trained CrossFit individual. The combination of proprietary supplements taken may provide benefits for removing the blood lactate during high-intensity functional exercise.
