At present, graduates of international pharmacy schools can apply to take the Korean Pharmacist Licensing Examination after passing a review by the Accreditation Board of the Pharmacy Schools and Licenses. However, since the educational content of different schools and the roles of pharmacists differ from country to country, a preliminary examination might be necessary before the Pharmacist Licensing Examination. To prepare to implement a preliminary examination for foreign pharmacy graduates in Korea, we summarized the preliminary examinations used in four other countries and presented a proposal for a preliminary examination. Data were collected via the internet and through telephone interviews with appropriate persons. The proposal was revised after a public forum. There are preliminary examinations in the USA, Canada, Australia, and the United Kingdom, and these involve written, oral, practice, and English proficiency tests. We proposed that the Korean preliminary examination consist of a written test on basic pharmacy, a test in the Korean language, and an interview. The preliminary examination should include suitable items that effectively evaluate international graduates. Graduates of international pharmacy schools who have an ability equivalent to graduates of Korean pharmacy schools should be eligible to write the Korean Licensing Examination.

The inner ear is composed of a cochlear duct and five vestibular organs in which mechanosensory hair cells play critical roles in receiving and relaying sound and balance signals to the brain. To identify novel genes associated with hair cell differentiation or function, we analyzed an archived gene expression dataset from embryonic mouse inner ear tissues. Since atonal homolog 1a (Atoh1) is a well known factor required for hair cell differentiation, we searched for genes expressed in a similar pattern with Atoh1 during inner ear development. The list from our analysis includes many genes previously reported to be involved in hair cell differentiation such as Myo6, Tecta, Myo7a, Cdh23, Atp6v1b1, and Gfi1. In addition, we identified many other genes that have not been associated with hair cell differentiation, including Tekt2, Spag6, Smpx, Lmod1, Myh7b, Kif9, Ttyh1, Scn11a and Cnga2. We examined expression patterns of some of the newly identified genes using real-time polymerase chain reaction and in situ hybridization. For example, Smpx and Tekt2, which are regulators for cytoskeletal dynamics, were shown specifically expressed in the hair cells, suggesting a possible role in hair cell differentiation or function. Here, by reanalyzing archived genetic profiling data, we identified a list of novel genes possibly involved in hair cell differentiation.

A crude drug “Dang-Gui”, belonging to the genus Angelica, has been used as a traditional herbal medicine in Asia. Various studies have investigated the chemical components and pharmacological activities of Dang-Gui worldwide. However, domestic research results published in Korean are undervalued in international academia due to language barriers. Therefore, it is necessary to summarize the domestic research findings systematically for greater accessibility. This review focuses on the results published in four Korean pharmaceutical journals between 1970 and 2018, which detail the botanical, phytochemical, and pharmacological properties of three Angelica species (A. gigas, A. sinensis, and A. acutiloba) used as “Dang-Gui” in Korea, China, and Japan.

Most of the patients with hemorrhagic fever with renal syndrome (HFRS) by Hantaviruses recover completely. However, the prevalence of hypopituitarism as sequel of HFRS may be approximately 10%. However, it is rare for hyponatremia to present as a manifestation of hypopituitarism due to HFRS. A 42-year-old Asian woman presented with anorexia, nausea, and vomiting. She had a history of HFRS 7 years ago. During her first hospital admission, her serum sodium was 103 mmol/L. The rapid adrenocorticotropic hormone (ACTH) stimulation test showed no abnormal findings suggesting the possibility of adrenal insufficiency. After she underwent fluid therapy for 5 days, her serum sodium level was slightly increased to 131 mmol/L, and her clinical symptoms were improving. The next day after she was discharged, she suffered from the same symptoms and was admitted to our hospital again. On the day of her second admission, her serum sodium was 117 mmol/L. A combined pituitary function test showed diminished function of the anterior pituitary gland, which led to secondary adrenal insufficiency. Magnetic resonance imaging findings of her sella were compatible with empty sella turcica. After the replacement of prednisolone, her serum sodium levels returned to normal. Pituitary dysfunction should be included in the differential diagnosis of severe hyponatremia, especially in patients who suffered HFRS. This case also suggests that the rapid ACTH stimulation test has limitations with regard to the differential diagnosis of primary or secondary adrenal insufficiency.

BACKGROUND: The purpose of this retrospective and prospective study is to evaluate the efficiency of ultrasound (US) guidance as a method of decreasing the malposition rate of central venous catheterization (CVC) in the emergency department (ED). METHODS: We retrospectively enrolled 379 patients who underwent landmark-guided CVC (Group A) and prospectively enrolled 411 patients who underwent US-guided CVC (Group B) in the ED of a tertiary hospital. Malposition of the CVC tip is identified when the tip is not located in the superior vena cava (SVC). In Group B, we performed US-guided intravascular guide-wire repositioning and then confirmed the location of the CVC tip with chest radiography when the guide-wire was visible in any three other vessels rather than in the approached vessel. In the case of a guide-wire inserted into the right subclavian vein (SCV), the left SCV and both internal jugular veins (IJV) were referred to as the three other vessels. The two subject groups were compared in terms of the malposition rate using Fisher's exact test (significance = p < 0.05). RESULTS: There were 38 malposition cases out of a total of 790 CVCs. The malposition rates of Groups A and B were 5.5% (21) and 4.1% (17), respectively, and no statistically significant difference in malposition rate between the two groups was found. In Group B, the malposition rate was decreased from 4.1% (17) to 1.2% (5) after the guide-wire was repositioned with US guidance, which led to a statistically significant difference in malposition rate (p < 0.01). CONCLUSIONS: The authors concluded that repositioning the guide-wire with US guidance increased correct placement of central venous catheters toward the SVC.

PURPOSE: The Korean Triage and Acuity Scale (KTAS), which was developed in 2012 due to the need for a single triage tool for emergency patients in Korea, has since become nationalized. Although five years has passed, there has been limited evidence of its validation. Therefore, this study was conducted to analyze the validity of the new triage system. METHODS: We conducted a multicenter prospective study. Data were collected from seven hospitals and 42,187 patients were classified using the KTAS from April 1, 2013 to July 6, 2014. We analyzed whether the indirect severity variables showed meaningful differences according to KTAS levels. The variables consisted of disposition from emergency room, length of stay, numbers of consultations, examination of computed tomography, emergency room costs, and performance of emergent interventions. RESULTS: From KTAS level 1 to 5, a decreasing trend in the length of stay in emergency room, frequency of consultation with other departments, admission, computed tomography rate, emergency intervention rate, and emergency room costs was observed. Upon binominal logistic regression, disposition from emergency room and emergent intervention rate showed the highest odds ratio with statistical significance. CONCLUSION: The results of this study demonstrated that KTAS is a valid emergency triage tool that reflects the severity of the patient with indirect indicators. The results of this study will be useful as a reference for quality control of KTAS.

Anthocyanins are water soluble plant pigments which are responsible for the blue, red, pink, violet colors in several plant organs such as flowers, fruits, leaves and roots. In recent years, anthocyanin-rich foods have been favored as dietary supplements and health care products due to diverse biological activities of anthocyanins including antioxidant, anti-allergic, anti-diabetic, anti-microbial, anti-cancer and preventing cardiovascular disease. High-performance countercurrent chromatography (HPCCC) coupled with reversed-phase medium pressure liquid chromatography (RP MPLC) method was applied for the rapid and efficient isolation of cyanidin 3-glucoside (C3G) and peonidin 3-glucoside (P3G) from black rice (Oryza sativa L., Poaceae). The crude black rice extract (500 mg) was subjected to HPCCC using two-phase solvent system composed of tert-butyl methyl ether/n-butanol/acetonitrile/0.01% trifluoroacetic acid (TBME/B/A/0.01% TFA, 1 : 3 : 1 : 5, v/v, flow rate - 4.5 mL/min, reversed phase mode) to give enriched anthocyanin extract (37.4 mg), and enriched anthocyanin extract was sequentially chromatographed on RP-MPLC to yield C3G (16.5 mg) and P3G (8.7 mg). The recovery rate and purity of isolated C3G were 76.0% and 98.2%, respectively, and those of P3G were 58.3% and 96.3%, respectively. The present study indicates that HPCCC coupled with RP-MPLC method is more rapid and efficient than multi-step conventional column chromatography for the separation of anthocyanins.

OBJECTIVE: Central venous catheter (CVC) misplacement can result in incorrect readings of the central venous pressure, vascular erosion, and intravascular thrombosis. Several studies have examined the correlation between the guidewire J-tip direction and misplacement rate. This study examined whether the guidewire J-tip direction (cephalad vs. caudad) affects the misplacement rate in right subclavian venous catheterization. METHODS: This prospective randomized controlled study was conducted between February 2016 and February 2017. The subjects were divided into two groups (cephalad group vs. caudad group) and the misplacement rate was compared according to guidewire J-tip direction in each group. RESULTS: Of 100 patients, the cephalad and caudad groups contained 50 patients each. The age, sex, and operator experience were similar in the two groups. In the cephalad group, misplacement of CVC insertion into the ipsilateral internal jugular vein occurred in two cases. In the caudad group, misplacement of CVC insertion into the contralateral subclavian vein occurred in one case, with loop formation in the brachiocephalic trunk in one case. Guidewire J-tip direction showed no significant correlation with CVC misplacement. CONCLUSION: The guidewire J-tip direction does not influence the rate of misplacement.
