Atopic dermatitis (AD) is the most common inflammatory pruritic skin disease worldwide, characterized by the infiltration of multiple pathogenic T lymphocytes and histological symptoms such as epidermal and dermal thickening. This study aims to investigate the effect of vinpocetine (Vinp; a phosphodiesterase 1 inhibitor) on a 1-chloro-2,4-dinitrobenzene (DNCB)-induced AD-like model. DNCB (1%) was administered on day 1 in the AD model. Subsequently, from day 14 onward, mice in each group (Vinp-treated groups: 1 mg/kg and 2 mg/kg and dexamethasone- treated group: 2 mg/kg) were administered 100 µl of a specific drug daily, whereas 0.2% DNCB was administered every other day for 30 min over 14 days. The Vinp-treated groups showed improved Eczema Area and Severity Index scores and trans-epidermal water loss, indicating the efficacy of Vinp in improving AD and enhancing skin barrier function. Histological analysis further confirmed the reduction in hyperplasia of the epidermis and the infiltration of inflammatory cells, including macrophages, eosinophils, and mast cells, with Vinp treatment. Moreover, Vinp reduced serum concentrations of IgE, interleukin (IL)-6, IL-13, and monocyte chemotactic protein-1. The mRNA levels of IL-1β, IL-6, Thymic stromal lymphopoietin, and transforming growth factor-beta (TGF-β) were reduced by Vinp treatment. Reduction of TGF-β protein by Vinp in skin tissue was also observed. Collectively, our results underscore the effectiveness of Vinp in mitigating DNCB-induced AD by modulating the expression of various biomarkers. Consequently, Vinp is a promising therapeutic candidate for treating AD.

This is a retrospective study on condylar fracture of mandible. The stucy based on a series of 112 patients who had treated for the fractures of mandibular condyle on Kyunghee Dental Hospital from January, 1989 to August 1997. We studied the age and sex distributions, causes of fractures, location of fractures and so on. The results as follow : 1. The ratio of male : female was 4:1, and the highest frequency of condylar fractures was registered among patients aged to 21 to 30 years. 2. The most common cause of condylar fractures was fall-down(47.7%), followed in incidence by direct-blow(27.9%) and traffic accidents(20.7%). 3. Subcondylar fracture had highest incidence(50%), and followed by condyle head(27.4%) and condylar neck(22.6%). 4. 9.7% of condylar fractures had occurred bilaterally and in cases of bilateral condylar fractures, condylar head fractures(58.33%) was hightest incidence. 5. Mandibular symphysis was most commonly involved in condylar fracture(63.4%), and 27.7% of condylar fractures had not any other mandibular fractures.

Complicated malaria is mainly caused by Plasmodium falciparum, but, increasingly, Plasmodium vivax is also being reported as a cause. Since the reemergence of indigenous vivax malaria in 1993, cases of severe malaria have been steadily reported in Korea. Herein, we report a case of vivax malaria complicated by adult respiratory distress syndrome (ARDS) that was successfully managed with extracorporeal membrane oxygenation (ECMO). A 59-year-old man presented at our hospital with fever and abdominal pain, which had persisted for 10 days. On admission, the patient had impaired consciousness, shock, hypoxia and haziness in both lungs, jaundice, thrombocytopenia and disseminated intravascular coagulation, metabolic acidosis, and acute kidney injury. A peripheral blood smear and a rapid diagnostic test verified P. vivax mono-infection. Ten hours after admission, hypoxia became more severe, despite providing maximal ventilatory support. The administration of antimalarial agents, ECMO, and continuous venovenous hemofiltration resulted in an improvement of his vital signs and laboratory findings. He was discharged from the hospital 7 weeks later, without any sequelae.

Extranodal NK-T cell lymphoma is a subtype of non-Hodgkin's lymphoma (NHL) and this most commonly affects the nasal and paranasal cavities. Primary lymphoma of the gallbladder is extremely rare and solitary relapsed extranodal NK-T cell lymphoma of the gallbladder has not yet been reported in Korea. We experienced a case of a solitary relapsed extranodal NK-T cell lymphoma of the gallbladder. One year earlier, a 55-year-old man was diagnosed with extranodal NK-T cell lymphoma of the anus, and he underwent six cycles of chemotherapy with CHOP (cyclophosphamide, adriamycin, vincristine and prednisone), and he achieved complete remission. The patient was admitted for right upper quadrant pain. Computed tomography (CT) performed on readmission revealed gallbladder wall thickening. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed hypermetabolic lesions along the gallbladder wall. The specimen obtained at cholecystectomy revealed CD3(+) and CD56(+) lymphoma, which is characteristic of NK-T cell lymphoma.

BACKGROUND AND OBJECTIVES: We performed this study to evaluate the common carotid artery intima-media thickness (CCA IMT), and its correlation with several clinical variables, including the 10 year coronary heart disease (10 Yr CHD) risk in both healthy and hyperlipidemic hypertensive (HH) Koreans. SUBJECTS AND METHODS: This was a multi-centered prospective epidemiological study. The study population consisted of 227 healthy subjects without risk factors, with the exception of age (mean 49 years old, 114 males), and 243 HH subjects (mean 51 years old, 120 males). The carotid IMT and presence of plaques were semi automatically measured in both carotid arteries at a central reading facility. RESULTS: Linear regression analysis of all the subjects revealed that the independent factors of both CCA IMT were age, pulse pressure (PP) and HDL-cholesterol, and that of the right CCA IMT were sex and 10 Yr CHD risk. In healthy subjects, the independent factor of both CCA IMTs was age, and that of the right CCA IMT was body weight. In the HH subjects, age, sex, total cholesterol, HDL-cholesterol and PP were independent factors of both CCA IMTs, but 10 Yr CHD risk was an independent factor of only the right CCA IMT. Carotid plaques were seen in 17% of the healthy subjects and 35% of the HH subjects. An ROC curve analysis showed a right CCA IMT of 0.646 mm and left CCA IMT of 0.656 mm demonstrated 60% sensitivity and specificity in differentiating healthy from HH subjects. CONCLUSION: This result reliably demonstrates the Korean CCA IMT, as well as several other significant pieces of information.

PURPOSE: To evaluate the effectiveness and safety of fentanyl-TTS in the management of radiotherapy induced acute pain and cancer pain treated with radiotherapy. MATERIALS AND METHODS: Our study was open labelled prospective phase IV multi-center study. the study population included patients with more 4 numeric rating scale(NRS) score pain although managed with other analgesics or more than 6 NRS score pain without analgesics. Patients divided into two groups; patients with radiotherapy induced pain (Group A) and patients with cancer pain treated with radiotherapy (Group B). All patients received 25 ug/hr of fentanyl transdermal patch. Primary end point was pain relief; second end points were change in patient quality of life, a degree of satisfaction for patients and clinician, side effects. RESULTS: Between March 2005 and June 2005, 312 patients from 26 participating institutes were registered, but 249 patients completed this study. Total number of patients in each group was 185 in Group A, 64 in Group B. Mean age was 60 years and male to female ratio was 76:24. Severe pain NRS score at 2 weeks after the application of fentanyl was decreased from 7.03 to 4.01, p=0.003. There was a significant improvement in insomnia, social functioning, and quality of life. A degree of satisfaction for patients and clinician was very high. The most common reasons of patients' satisfactions was good pain control. Ninety six patients reported side effect. Nausea was the most common side effect. There was no serious side effect. CONCLUSION: Fentanyl-TTS was effective in both relieving pain with good tolerability and improving the quality of life for patients with radiotherapy induced acute pain and cancer pain treated with radiotherapy. The satisfaction of the patients and doctors was good. There was no major side effect.
