Silicone fluid is a biomaterial widely used in modern cosmetic procedures because there are few side effects, considerable chemical stability and predictable physical properties. However, many local and systemic adverse reactions have reported. In particular some serious pulmonary complications have been reported such as pulmonary thromboembolism, acute respiratory distress syndrome with some cases leading to mortality. Most of the serious complicated cases were induced by an illegal silicone fluid injection. We experienced two cases of acute respiratory distress syndrome with pulmonary hemorrhage induced by an illegal silicone fluid injection. The patients were 41 & 51 year old women, who complained of dyspnea. The chest X-ray and HRCT scan findings showed a bilateral ground glass attenuation on the bilateral dependent portion of the upper and middle lung zone. The patients clinical symptoms and the radiologic and other laboratory findings were compatible with acute respiratory distress syndrome induced by the silicon fluid injection. Here we report two cases of acute respiratory distress syndrome with pulmonary hemorrhage induced by an illegal silicone injection with a review of the relevant literature.

This research evaluated how the composition of Yak-sun(oriental diet therapy), taken as a nutritional supplement with daily meals, can effect the medical condition of those suffering from modern diseases like obesity and hyperlipideia. We produced Yak-sun tea, determined its nutrient composition and physical characteristics and evaluated how this tea effects affects the active oxygen concentration inside the body by clinical practices. The study results indicated that this tea significantly decrease active oxygen concentration. We think that scientific and objective evaluation was done on the components of Yak-sun tea prescription. We concluded that we could apply the components not only in the form of tea, but also in other food forms. The information we received from this conclusion will provide basic information for the application of oriental medicinal resources into other foods and will also be a steppingstone in the field of functional food research for the development of medicinal herbs which is already an important research field world-wide.

Biomarkers for preclinical diagnosis of cancer are valuable tools for detection of malignant tumors at early stages in groups at risk and screening healthy people, as well as monitoring disease recurrence after treatment of cancer. However the complexity of the body's response to the pathological processes makes it virtually impossible to evaluate this response to the development of the disease using a single biomarker that is present in the serum at low concentrations. An alternative approach to standard biomarker analysis is called immunosignature. Instead of going after biomarkers themselves this approach rely on the analysis of the humoral immune response to molecular changes associated with the development of pathological processes. It is known that antibodies are produced in response to proteins expressed during cancer development. Accordingly, the changes in antibody repertoire associated with tumor growth can serve as biomarkers of cancer. Immunosignature is a highly sensitive method for antibody repertoire analysis utilizing high density peptide microarrays. In the present review we discuss modern methods for antibody detection, as well as describe the principles and applications of immunosignature in research and clinical practice.

Recently detection of early gastric cancer (EGC) has been increasing and the treatment strategies for gastric cancer have been changing. The purpose of this study was to compare clinical outcomes between laparoscopically assisted (LADG) and hand-assisted laparoscopic gastrectomy (HALDG) and open distal gastrectomy for early gastric cancer. This review is directed toward providing gastric surgeons with recent advances in the treatment of EGC. We investigated the English language literature for the past 12 years through computer searches which focused on : 1) Patient demographics, 2) Operation time, 3) Intra-operative blood loss, 4) Depth of invasion, 5) CBC, 6)Weight loss, 7) Analgesic requirement, 8)Time NPO, 9) Length of hospital stay, 10) Tumor stage, 11) Lymph node (LN) dissection, 12) Position of LN resected, 13) Complications. Improved operative techniques and surgical instrumentation have facilitated the development of minimally invasive gastric cancer surgery. The short-term benefits of laparoscopic gastrectomy included less surgical trauma, less pain, rapid return of gastrointestinal function, and shorter hospital stay, with no change in operative outcome. Laparoscopic gastrectomy was better accepted by the patients as a good procedure and promptly brought the patients back to their previous lifestyle and activities of daily living. But the advantages of HALDG for gastric cancer, extended lymph node dissection and intracorporeal anastomosis are feasible and easier with the presence of the internal hand. The hand-assisted laparoscopic (HALDG) method reported the best results in lymph node dissection.This method is an alternative to total laparoscopic radical gastrectomy. LADG and HALDG, when compared with conventional open gastrectomy, have several advantages. When performed by a skilled surgeon, LADG and HALDG are safe and useful techniques for patients with early-stage gastric cancer. Their appropriateness for gastric cancer surgery require further study.

Periprosthetic femoral fractures remain as one of the most challenging complications following total hip arthroplasty. A thorough clinical and radiographic evaluation, precise classification, and understanding of modern management principles are essential to obtain optimal results for these fractures. The Vancouver classification system is a simple, effective, and reproducible method for the planning treatments of these injuries. The fractures associated with a stable femoral stem can be treated effectively with osteosynthesis, but periprosthetic femoral fractures associated with a loose stem require revision arthroplasty. This paper describes the principle of the treatment of patients with periprosthetic femoral fractures and how to assess the stability of the femoral stem.

Objective : It is well known that modern chemotherapy against cancer has side effects to a living body, especially hemopoietic and immunologial disfunctions. However, there are no effective ways to reduce them. Recently, traditional Korean herb medicine has been reported to have some biological modifying responses. Therefore, we hypothesized that additional application of herb medicine during chemotherapy is more effective to reduce its side effects. While we were studying the effects, we have observed the inhibitory effect of Soamgudamikgitang on formation of side effects derived from Cyclophosphamide, it has been used in clinical practice at Kyung Hee Medical Center. Methods : We injected 200mg/kg of Cyclophosphamide, one time, to an experimental group, consisting of ten mice. We divided them into eight groups: normal, CPX, SAKT 2mg, SAKT 10mg, SAKT 50mg, SAKT 2mg, CPX, SAKT 10mg+CPX, SAKT 50mg+CPX. We injected Soamgudamikgitang seven days, five days, three days, and one day before we injected CPX. One day, three days, and five days after CPX injection, we injected Soamgudamikgitang again and then killed all the mice. The parameters determined in this experiment were daily body weight liver and spleen weight, RBC, WBC, and platelet for hemopoietic dysfunction and AST, ALT for hepatotoxicity, BUN, creatine for renal toxcity, lymphocyte proliferation activity and lymphocyte subsets for immunological toxcity. Results : We have found that Soamgudamikgitang has inhibitory effects on the formation of Cyclophosphamide's side effects. Significant differences between the group, which contained Cyclophosphamide, and the other group, which contains Cyclophosphamide and 2, 10, 50mg of Soamgudamikgitang respectively were observed. Platelets(2mg of Soamgudamikgitang, p<0.05 ;10mg, p<0.01 ;50mg, p<0.001), liver weight(50mg, p<0.01), spleen weight(10mg, p<0.05), AST(all groups, p<0.01), ALT(2mg, p<0.01 ;10mg, p<0.05 ;50mg, p<0.01), BUN(2mg, p<0.01 ;50mg, p<0.05). Although immunological in both lymphocyte proliferation and its subsets were not observed, which shows that Soamgudamikgitang has a strong effect on T cell activities. Conclusions : From the above results, we can expect that the combined therapy of Soamgudamikgitang and Cyclophosphamide is more effective for treating cancer patients.

The prevalence rate of pulmonary tuberculosis is 1.8% in 1990, and endobronchial tuberculosis may exist in 10 to 40% of active disease. Endobronchial tuberculosis usually leaves bronchial stenosis as the complication despite of modern chemotherapy, and it is often misdiagnosed as bronchial asthma. When bronchial stenosis involves major airway, its treatment needs such special measures as steroid therapy, surgical intervention and/or laser therapy, but the therapeutic result is often disappointing. To exploit a new treatment modality for bronchial stenosis, balloon dilatation was carried out in 12 patients with endobronchial tuberculosis. Under local anesthesia, 4F-Fogarty balloon was inserted via bronchofiberscope in ten cases and 10F-Gruentzig balloon was introduced under fluoroscopic guide in two others. Endobronchial tuberculoses were subdivided into two(16.7%) with actively caseating type, seven (58.3%) with fibrostenotic type, and three (25.0%) with stenotic type without fibrosis, according to the bronchoscopic findings. In 7 healed cases which were all stenotic with fibrosis, three (42.9%) took favorable turn in clinical status but four (57.1%) were not improved with balloon dilatation. In 5 active cases, all (two with actively-caseating type and three with stenotic type without fibrosis) were improved with this method. $FEV_{1.0}$ or FVC increased 10% or more after procedure in seven (70.0%) of ten and bronchial lumen remained enlarged in eight (66.7%) of twelve, in whom follow-up examination was done after the procedure. Balloon dilatation of bronchial stenosis is more effective, when endobronchial tuberculosis is in active stage than in healed fibrotic stage. It is suggested that bronchial stenosis can be minimized by early diagnosis and early application of balloon dilatation in the course of disease.

The term pharmacognosy as applied to a constituent scientific discipline of Korean Medical Food (KMF) has been in use for nearly several years, and it refers to studies on the pharmacological properties of natural products foods. During the last half of the 20th century, pharmacognosy for KMF evolved from being a descriptive botanical subject to one having a more chemical and biological focus. At the beginning of the 21st century, teaching pharmacognosy for KMF teaching in academic culinary arts and natural healing institutions has been given new relevance as a result of the explosive growth in the use of herbal foods (health foods) in modern KMF practice. In turn, pharmacognosy for KMF research areas are continuing to expand, and now include aspects of cellular and molecular biology in relation to natural products, ethnobotany and phytotherapy, in addition to the more traditional analytical method development and phytochemistry. Examples are provided in this review of promising bioactive compounds obtained in two multidisciplinary natural product KMF development and discovery projects, aimed at the elucidation of new plant-derived cancer chemotherapeutic agents and novel cancer chemopreventives, respectively. The systematic study of KMF offers pharmacognosy groups an attractive new area of research, ranging from investigating the biologically active principles of KMF and their mode of action and potential active substance interactions, to sanitary and quality control, and involvement in clinical trials.

Atopy is a highly prevalent and serious health problem. The prevalence and severity of asthma and allergic diseases have increased over recent decades, particularly in industrialized nations. Early life infections may protect against the development of atopy and allergic diseases like asthma. The inverse relationship between the incidence of atopy and childhood infections has led to the 'hygiene hypothesis', which suggests that diminished exposure to childhood infections in modern society has led to decreased Th1-type responses. Th1 and Th2 responses are counter-regulatory. Reduced Th1 may lead to enhanced Th2-type inflammation, which is important in promoting asthma and allergic disease via up-regulation of IL-4, IL-5, and IL-13. It is now widely accepted that altered regulation of Th2 responses(and possibly the balance between Th1 and Th2 responses) is an important factor in the development of atopy. CpG DNA represent a novel class of drugs with substantial immunomodulatory properties. CpG DNA contain unmethylated motifs centered on the CpG dinucleotides, like bacterial DNA. These CpG DNA promote Th1 and regulatory type immune responses and suppress Th2 responses. In murine studies, CpG DNA are effective in prevention and treatment of asthma and allergic diseases. CpG DNA are just beginning to be tested in human asthma. While its precise mechanisms continue to be fully studied, CpG DNA offers considerable promise as a novel treatment for atopic inflammation. It may prove to be an important disease modifying therapy, or even curative therapeutic agent for asthma and allergic diseases.

A conflict of interest is usually defined as a set of circumstances that creates a risk that professional judgments or actions regarding a primary interest will be unduly influenced by a secondary interest. In general, a conflict of interest can be classified as either a financial or a non-financial one. A financial conflict of interest reportedly occurs frequently in medical (and psychiatric) research and practice and is associated with a greater likelihood of reporting results favorable to the intervention being studied. A non-financial conflict of interest may occur in psychiatric research and practice as a result of the so-called "allegiance effect." It is very important that clinicians and researchers in the field of psychiatry be aware that their field is vulnerable to both financial and non-financial conflicts of interest. Considering that it is impossible in modern psychiatry to be completely free from possible conflicts of interest, the best way to manage a conflict of interest is disclosure based on the principles of transparency. Actions that might lead to conflicts of interest should be avoided as much as possible.
