Heat disorders are not uncommon in the military society due to supposedly hard training to overcome the environmental conditions. Twenty-two soldiers with heat disorders were admitted to Chin Hae Naval Hospital June 1969 through July 1970. Hoping that our clinical studies on them contribute to a renewed understanding, the results are reported in summary as follows: 1) Heat disorders occurred with an overall incidence of 3.1 per cent during running in early summer. 2) Of the twenty-two patients, eight (37 per cent) had heat cramps, six (27 per cent) heat exhaustion, five(23 per cent) heat stroke, and three(13 per cent) had undetermined disorder. 3) Ten patients(45 per cent) were comatous, and this occurred most frequently(80 per cent) among those with heat stroke. 4) All patients were grouped into four according to their physical status on admission. Those with heat exhaustion mostly belonged to group I (good) or group II (fair). Those with heat stroke and heat cramps eomprised most of group III (poor) and group IV (grave). 5) Group I and II patients recovered within 12 hours; group III, within 12~24 hours; and group IV, required more than 24 hours of care. 6) One patient with heat stroke, graded V, expired with sudden hypothermia 15 hours following admission. Overall mortality of heat disorders was 4.5 per cent, and that of heat stroke 20 per cent. 7) The rest recovered uneventfully within 19 hours of average.

The contour of mandibular angle is important for facial esthetics in the oriental population, because the wide and square face is thought to have had an unhappy life. A prominent mandibular angle produces a characteristics quardrangle, coase, and muscular appearance. So, uni- or bi-lateral mandibular angle reduction is usually performed. However, there is little guideline for bi-lateral angle reduction. So, this study was to investigate the pattern of Korean mandibular angle for bi-lateral mandibular angle reduction as guideline. This study was included 66 adult men and women over 19 years old who are having the normal mandibular angle. We measured the posterior border, angle, and inferior border of mandible using cephalometric view. The results of study was as followed : 1. The ratio of posterior mandible was 96.6, 97.3% in male, and 103.0, 106.0% in female. 2. The ratio of mandibular angle(R1-Go/R1-R2) was 120.2% in male, and 117.3% in female. 3. The ratio of inferior mandible(D5, 6, 7, E, F, G/D4) was 97. 3, 90.9, 79.5, 65.2, 57.8, 46.9% in male, and 98.5, 91.2, 80.5, 67.6, 59.1, 50.2 % in female. The results of this study should be useful to decide accurate amount of reduction.

Langerhans cell histiocytosis is a rare disorder with abnormal proliferation of histiocytes. Besides the infiltration of a variety of organs, patients with Langerhans cell histiocytosis can develop sclerosing cholangitis, with bile duct involvement, progressive fibrosis, and cirrhosis. We report a case of Langerhans cell histiocytosis with sclerosing cholangitis. Endoscopic retrograde cholangiopancreatography revealed multiple strictures and dilatations of left intrahepatic and extrahepatic bile duct. Endoscopic biopsy of common bile duct showed diffuse infiltration of histiocytes and eosinophiles in lamina propria. Immunohistochemical stain showed positive reactions for S-100 and CD1a and a negative reaction for cytokeratin in infiltrating histiocytes.

Background/Aims:
DW1601, an oral fixed dose combination syrup composed of DW16011 and Pelargonium sidoides, was developed to enhance the symptom relief effect in patients with acute bronchitis. We evaluated the efficacy and safety of DW1601 compared to DW16011 or P. sidoides for treatment of acute bronchitis using a randomized, double-blind, placebocontrolled, multi-centre trial design.
Methods:
A total of 204 patients with acute bronchitis was randomized 1:1:1 to receive DW1601 (n = 67), DW16011 (n = 70), or P. sidoides (n = 64) for 7 days. The primary outcome was efficacy of DW1601 compared to DW16011 or P. sidoides in reducing the total bronchitis severity score (BSS) at day 4 of treatment. Secondary endpoints were changes in total and symptomspecific BSS, response rate and patient satisfaction rate. Safety analysis was assessed at day 7.
Results:
At 4 days after medication, decrease of total BSS from baseline was significantly greater in the DW1601 group than in the DW16011 group (–3.51 ± 0.18 vs. –2.65 ± 0.18, p = 0.001) or P. sidoides group (–3.56 ± 0.18 vs. –2.64 ± 0.19, p < 0.001). In addition, the BSS total score at day 7 and the BSS cough and sputum component scores at days 4 and 7 were significantly more improved with DW1601 treatment compared with the DW16011 group or P. sidoides group. Participants treated with DW1601 showed higher rates of response and satisfaction than control groups (response rate, DW1601, 100% vs. DW16011, 85.7% vs. P. sidoides, 85.9%; satisfaction rate, DW1601, 92.6% vs. DW16011, 82.9% vs. P. sidoides, 81.2%). Significant adverse events were not observed in the DW1601 group.
Conclusions
DW1601 is superior to DW16011 or P. sidoides in improving symptoms of acute bronchitis.

Lepidium sativum (LS) is an annual plant that has been used for the treatment of many ailments. The ethanol extracts of pinnately-lobed (PL), pinnately-compound (PC), and pinnately-veined (PV) leaves of LS were examined for their total polyphenol and flavonoid contents, and their phenolic acid (namely caffeic acid (CA), p-coumaric acid (PA), and ferulic acid (FA)) contents were determined using reverse-phase high-performance liquid chromatography-photodiode array (HPLC/PDA) analysis. Among the three leaf types, the highest average total polyphenol content was found in PV (79.87 mg GAE/g extract), whereas PC showed the highest average total flavonoid content (53.35 mg QE/g extract). According to the HPLC/PDA results, PV exhibited a high amount of CA (78.60 µg/g extract) and FA (1,722.85 µg/g extract), whereas a high content of PA (258.72 µg/g extract) was detected in PC. Higher amounts of the phytochemical compounds PV and PC might be indicative of their superior biological activities compared to PL. To the best of our knowledge, this study is the first to quantify and compare the total polyphenol, flavonoid, and phenolic acid contents in three different leaf types of LS.

We report five cases of cytomegalovirus infection in immunocompromised patients which were detected by either cytomegalovirus antigenemia assay or in situ hybridization. Four cases had leukemia and the other had chronic renal failure. All the three BMT recipients suffered from GvHD. Interestingly, there was an unique case of CMV disease without a history of BMT, which reminded us that CMV could attack immunocompromised patients who had not undergone transplantation, too. Four out of five cases died. We think that cytomegalovirus infection or disease should not be regarded as a minor problem in post-transplantation infection in Korea.

In this study, we investigated the effects of pelargonidin, an anthocyanidin found in many fruits and vegetables, on endothelium-independent vascular contractility to determine the underlying mechanism of relaxation. Isometric contractions of denuded aortic muscles from male rats were recorded, and the data were combined with those obtained in western blot analysis. Pelargonidin significantly inhibited fluoride-, thromboxane A2-, and phorbol ester-induced vascular contractions, regardless of the presence or absence of endothelium, suggesting a direct effect of the compound on vascular smooth muscles via a different pathway. Pelargonidin significantly inhibited the fluoride-dependent increase in the level of myosin phosphatase target subunit 1 (MYPT1) phosphorylation at Thr-855 and the phorbol 12,13-dibutyrate-dependent increase in the level of extracellular signal-regulated kinase (ERK) 1/2 phosphorylation at Thr202/Tyr204, suggesting the inhibition of Rho-kinase and mitogen-activated protein kinase kinase (MEK) activities and subsequent phosphorylation of MYPT1 and ERK1/2. These results suggest that the relaxation effect of pelargonidin on agonist-dependent vascular contractions includes inhibition of Rho-kinase and MEK activities, independent of the endothelial function.

Background:
and Purpose: This clinical practice guideline provides evidence-based recommendations for treatment of dementia, focusing on cholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonists for Alzheimer’s disease (AD) and other types of dementia.
Methods:
Using the Population, Intervention, Comparison, Outcomes (PICO) framework, we developed key clinical questions and conducted systematic literature reviews. A multidisciplinary panel of experts, organized by the Korean Dementia Association, evaluated randomized controlled trials and observational studies. Recommendations were graded for evidence quality and strength using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology.
Results:
Three main recommendations are presented: (1) For AD, cholinesterase inhibitors (donepezil, rivastigmine, galantamine) are strongly recommended for improving cognition and daily function based on moderate evidence; (2) Cholinesterase inhibitors are conditionally recommended for vascular dementia and Parkinson’s disease dementia, with a strong recommendation for Lewy body dementia; (3) For moderate to severe AD, NMDA receptor antagonist (memantine) is strongly recommended, demonstrating significant cognitive and functional improvements. Both drug classes showed favorable safety profiles with manageable side effects.
Conclusions
This guideline offers standardized, evidence-based pharmacologic recommendations for dementia management, with specific guidance on cholinesterase inhibitors and NMDA receptor antagonists. It aims to support clinical decision-making and improve patient outcomes in dementia care. Further updates will address emerging treatments, including amyloid-targeting therapies, to reflect advances in dementia management.
