  • Leflunomide, a disease-modifying antirheumatic drug (DMARD) for the treatment of rheumatoid arthritis has been available in Korea since 2003. Leflunomide-associated interstitial pneumonitis has been appearing recently. A 25-year-old woman with a 12-month history of seronegative rheumatoid arthritis (RA) presented with acute respiratory insufficiency. She developed fever, dyspnea, and non-productive cough. Her medication history included methotrexate (15 mg/week. commencing 1 year prior) and leflunomide (20 mg/day, no loading dose, commencing 4 months prior). She was diagnosed with leflunomide-associated interstitial pneumonitis based on history, physical examination, laboratory and radiologic findings. She recovered quickly after leflunomide was withdrawn and steroids and cholestyramine were initiated quickly. We report a case of leflunomide-associated interstitial pneumonitis treated successfully with intravenous high-dose steroid and cholestyramine.

  • Purpose: The purpose of this study was to investigate the effects of a delirium prevention intervention for patients in neurology and neurosurgery intensive care units (ICUs). Methods: This study was a quasi-experimental study. Participants were 87 patients. The experimental group was provided with nonpharmacologic and multicomponent delirium prevention interventions, consisting of regular delirium assessment, improvement in orientation, early therapeutic intervention, and environmental interventions. The control group was provided with routine intensive care. Data were analyzed using $x^2$ test, Fisher's exact test, and t-test. Results: Both groups were homogeneous. The incidence of delirium and length of hospitalization were significantly lower in the experimental group compared to the control group. ICU stay, mortality and unplanned extubation were lower in the experimental group compared to the control group, but there was no significant difference. Conclusion: Findings indicate that the delirium prevention intervention is effective in reducing incidence of delirium and length of hospitalization. Therefore, this intervention should be helpful in preventing delirium in neurology and neurosurgery ICUs and can be used as a guide in the prevention of delirium in neurological diseases's patients.

  • In this study, the regional climate model, RegCM4.0 (25 km), with the HadGEM2-AO data as boundary conditions, was used to simulate the mean climate changes in the mid and late 21st century for CORDEX Phase 2 East Asian region. 122 years (1979~2100) of simulation were performed, and RCP 4.5 and RCP 8.5 were used for the simulation of future climate. In the mid-21st century, the temperature is expected to increase by about 0.5 to $3.0^{\circ}C$ in all regions of East Asia, regardless of season and scenario. The increase in temperature is greater in summer and winter, especially in the northern part of simulation domain. Interannual variability (IAV) is expected to decrease by 25% in summer for RCP 8.5, while it is expected to increase by more than 30% in autumn for both scenarios. Regardless of the scenario, the precipitation in South Korea is expected to increase in late June but decrease in mid-July, with an increase in precipitation greater than $100mm\;day^{-1}$. In RCP 4.5 of the late 21st century, relatively uniform temperature increase ($1.0{\sim}2.5^{\circ}C$) is expected throughout the continent, while RCP 8.5 shows a very diverse increase ($3.0{\sim}6.0^{\circ}C$) depending on season and geographical location. In addition, the IAV of temperature is expected to decrease by more than 35% in both scenarios in the summer. In most of the Northwest Pacific region, precipitation is expected to decrease in all seasons except for the summer, but in South Korea, it is projected to increase by about 10% in all seasons except autumn.

  • Purpose: The aim of this study was to evaluate the result of combined first metatarsal and calcaneal osteotomy for static cavovarus deformity of the foot. Materials and Methods: We performed a dorsal closing wedge $1^{st}$ metatarsal osteotomy and a lateral and upward displacement calcaneal osteotomy for 9 patients, 12 feet (6 male and 3 female). The mean age at the time of operation was 37 years and the mean followup period was 27 months. The causes of deformity were 2 poliomyelitis, 1 cerebral palsy, 1 Charcot-Marie-Tooth disease and 5 idiopathic type. Five lateral ligament reconstructions of the ankle and six percutaneous Achilles tendon lengthenings were added. The surgical results in terms of pain, function and alignment of the foot were evaluated by means of AOFAS ankle-hindfoot score and talo-$1^{st}$ metatarsal, calcaneus-$1^{st}$ metatarsal and calcaneal pitch angles were checked with weight bearing radiographs in lateral projection. Results: Talo-$1^{st}$ metatarsal and calcaneal pitch angles were reduced from the mean preoperative values of $21^{\circ}$ and $25^{\circ}$ to $12^{\circ}$ and $19^{\circ}$, respectively, at last followup. Also, calcaneus-$1^{st}$ metatarsal angle was increased from the mean $114^{\circ}$ to $114^{\circ}$. The mean AOFAS score was improved from 44.5 points preoperatively to 89.2 points at followup. There were 1 metatarso-cueiform joint nonunion, 1 sural nerve injury and 3 remaining symptomatic claw toes. Conclusion: Combined first metatarsal and calcaneal osteotomy appears to be an effective procedure for the treatment of adult static cavovarus foot.

  • This study was examined for effects of acupuncture of Zusanli (ST36) on the abdominal thermography of health subject. The volunteers who participating in this study had taken rest for 20-30 mins in room temperature (23-$25^{\circ}C$) before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day. The thermography of abdomen including a below part of the chest was taken using Infra-Red Imaging System (IR 2000, MEDI-CORE Co, Korea) by time interval of 15 minutes at 15 min before, just before and 15 min after, 30 min after and 45 min after acupuncture stimulation. Acupuncture was applied to the left ST36 acupoint for 30 mins. The results showed that acupuncture of ST36 significantly had more potencies of changes on all the of abdominal thermography than those of control group. Also, it was observed that the quantities of thermal changes following acupuncture of ST36 been increased significantly comparing that of control group at all the ROIs (region of interest). Observed the thermography classified by ROI, however, it was failed that acupuncture of ST36 could modulate the specific areas concerning to the abdominal pathway of Stomach Meridian. These results suggest that acupuncture of ST36 may modulate thermal distributions and changes of abdominal areas including the below of chest.

  • Objectives : To investigate the meaning and the importance of needling or moxibustion- prohibited acupoints in Chimgugapeulgyeong(鍼灸甲乙經). Methods : We found needling or moxibustion-prohibited acupoints in Chimgugapeulgyeong, then investigated the causes of the prohibitions from the various literatures and the anatomical structures near the acupoints. Results : In Chimgugapeulgyeong, the needling and moxibustion-prohibited points were ST9, ST17, ST32, CV5, and CV15. The needling-prohibited points were LU2, LI13, ST12, BL56, KI2, KI7, TE8, TE19, GB3, CV8, GV24, and jwagak(左角). The moxibustion-prohibited points were LU3, LU8, ST1, ST7, ST8, ST30, ST33, BL5, BL6, BL15, BL30, TE18, TE21, TE23, GB22, GB33, GB42, GV6, GV15, GV16, GV17 and GV25. The major cause of developing prohibited needling or moxibustion was due to the possibility to damage vessels or organs near them; other causes were side effects brought by applying wrong stimulating method or inducing women sterilized. Conclusions : The prohibition of needling or moxibustion on the points found in Chimgugapeulgyeong had acceptable causes. Therefore the techniques of needling or moxibustion on the acupoint should be performed with care.

  • We investigated fermentation characteristics and the amount of exopolysaccharide (EPS) produced, and the correlation between EPS and rheological properties in stirred yogurt fermented with Streptococcus thermophilus St-Body 1. The changes of pH and lactic acid concentrations of yogurt showed different patterns according to fermentation temperatures. About 20 to 40% of lactose was utilized during 6 hrs incubation. The higher number of lactic acid bacteria was obtained at 31℃ incubation temperature rather than other incubation temperatures. The higher amount of EPS was produced at 12 hr or 24 hr rather than other incubation period at the same fermentation temperatures. The viscosity continuously increased during the fermentation period, however the syneresis of yogurt was shown the lowest value at 37℃ for 30 hrs incubation. In physical properties, the hardness and adhesiveness increased continuously with decreasing cohesiveness and elasticity as incubation process was extended. The stirred yogurt fermented with S. thermophilus St-Body 1 at 37℃ for 24 hr resulted in the highest score at each sensory evaluation category.

  • Purpose: In this study, an in-house enzyme-linked immunosorbent assay (ELISA) was developed and validated. The titer of ELISA was calculated using the reference line (RFL) method based on the standard curve drawn using the international reference anti-mouse serum NIBSC (National Institute for Biological Standards and Control) 97/642. Materials and Methods: In the development step, signal to noise was depicted to select the buffers that showed the most appropriate ratio. In the validation step, standard range, precision, dilution linearity, and specificity were confirmed, and RFL and parallel line (PLL) methods were compared in precision and dilution linearity. Results: Coating concentration for plate was achieved at 0.1 ㎍/mL for pertussis toxin (PT), 0.15 ㎍/mL for filamentous hemagglutinin antigen (FHA), and 0.25 ㎍/mL for pertactin (PRN). The signal to noise ratio was 22.02 for PT, 14.93 for FHA, and 8.02 for PRN with 0.25% goat serum in phosphate-buffered saline (PBS) as a dilution buffer, and 2% skim milk in PBS as a blocking buffer. Based on the precision results, we assessed the lower limit of quantification by 1, 0.2, and 1.5 EU/mL concentration for PT, FHA, and PRN which met the ICH (International Council for Harmonization) M10 criteria of a 25% accuracy and total error of 40%. In specificity, homologous serum was spiked into heterologous serum and the accuracy met the criteria. There was no difference in the results between RFL and PLL calculations (p-value=0.3207 for PT, 0.7394 for FHA, 0.2109 for PRN). Conclusion: ELISA validated with RFL calculation method in this study is a relatively accurate assay for mouse humoral immunogenicity test.
