Objectives : Pyeongwi-san is widely used in Korean medicine for acute indigestion or gastrodynia. As a therapeutic agent for digestive diseases of modern people, in order to confirm the mechanism of Pyeongwi-san on digestive tract disease and the difference of therapeutic efficacy between its formulation, a comparative efficacy test was conducted on digestive tract disease animal model. Methods : For LPS enteritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san, and then intraperitoneally administered LPS one hour later to induce enteritis. After 5 hours, blood was collected and TNFα, IL-1β, IL-6 and PGE2 were confirmed by ELISA. For acute gastritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san according to the prescribed concentration, and then intraorally administered 60% ethanol and 150 mM HCl one hour later to induce acute gastritis. After 5 hours, blood was collected and TNFα,IL-6 were confirmed by ELISA. Results : In the LPS-administered enteritis animal model, Pyeongwi-san decreased TNFα, IL-1β, PGE2 and especially IL-6. Pyeongwi-san also decreased IL-6 in acute gastritis animal model. In addition, there was no significant difference in efficacy between the two formulations when compared with inflammatory markers. Conclusions : The efficacy of Pyeongwi-san was confirmed in the inflammatory markers related to digestive inflammatory diseases, and the efficay between two formulations of Pyeongwi-san was relatively similar. Further studies are needed to investigate the new applicability of Pyeongwi-san on different inflammatory diseases that have similar inflammation markers identified in this experiment.

Objectives : Huangqintang(⿈芩湯) is a famous herbal prescription in the Traditional Korean Medicine (e.g. Shanghanlun) to treat various chronic disease such as neurological disease and digestive system disease. Its components include Scutellariae Radix(⿈芩), Paeonia lactiflora(芍藥), Glycyrrhizae Radix et Rhizoma(⽢草), Zizyphi Fructus(⼤棗). Methods : In this study, we standardize the name, composition and medical uses of Huangqintang by literature studying and paper searching. Based on the comparison between oriental medicine and modern medicine pharmacology, we linked the medical uses of Huangqintang to Korean Standard Classification of Diseases (KCD). Results and Conclusion : The name of the prescription is unified into "Huangqintang", and its composition ratio between Scutellariae Radix, Paeonia lactiflora, Glycyrrhizae Radix et Rhizoma, and Zizyphi Fructus is 3:2:2:3. Huangqintang is used for enteritis diseases due to its antipyretic and antinflammatory effects. Its medical application was relatied with 'A'code, 'C'code, and 'K'code as indicated by KCD. By standardizing the mixed conceptions of Huangqintang, this review will facilitate the coding of Huangqintang prescription. Therefore, it will make Huangqintang prescription more useful in clinics.

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.

The Hippocratic aphorism, "the spitting of pur follows the spitting of blood, consumption follows the spitting of this, and death follows consumption," gives ancient documentation to the significance of hemoptysis in the intrathoracic disease. Hemoptysis is still one of the most alarming and startling of all symptoms. For most patients and not a few doctors, the expectoration of blood signals either pulmonary tuberculosis or cancer. But with the advent of modern thoracic surgical methods, differential diagnosis has become doubly important and appropriate treatment has provided the patients with full recovery or improvement of hemoptysis. Author reviewed 72 cases of patients with a chief complaint of hemoptysis, who were performed open thoracotomies in the Dept. of Thoracic and Cardiovascular Surgery, Pusan National University Hospital for 5 years from April 1980 to March 1985. The results were as follows: 1. The mean age of hemoptysis patients was 35.1 year old with a range from 16 to 64, and hemoptysis was most prevalent in the twenties and male dominant. 2. The most common underlying lung disease of hemoptysis was bronchiectasis [37.5%]. 3. The monthly peak frequency of hemoptysis was in the February [25.[%]. 4. Left lower lobe was the most common site of developing hemoptysis. 5. Lobectomy was the most frequent operative method of all open thoracotomies. 6. The hemoptysis caused by lung cancer recurred most frequently [21.4%], and the prognosis of operation was desperate. 7. The common postoperative complications of hemoptysis patient were re-hemoptysis [24%], bleeding [20%], and atelectasis [16%], and immediate postoperative mortality rate was 2.8%. was 2.8%.

The medical service, accompanied by various disease and disease of modern people, must collect various information about patients through various tests, and demand continued to increase. As a result, interest in waiting time for medical services is rising, and various studies are underway to reduce waiting time. However, medical procedure is complex and diverse in the procedure of the services need to be conducted for each procedure. In this study, we are going to propose ways to improve the waiting time of the test procedures that are basically experienced by outpatients through the simulation experimental method. Based on the actual measurement data, the Arena Simulation program was used to implement the hospital's ophthalmic examination model and alternative model. Through this analysis, the waiting time of the examination procedure, the size of the queue, and density of the waiting room were analyzed.

Vitamin D deficiency is prevalent, primarily due to limited sun exposure, which may be observed in urban areas, or as a result of modern lifestyles. Common myths about vitamin D persist, including that it is mostly obtained from the diet and is only essential for bone and mineral homeostasis. Nonetheless, advances in biomedical science suggest that vitamin D is a hormone that is integral to numerous physiologic functions in most cells and tissues. Therefore, abnormal vitamin D levels may contribute to health disturbances. A number of recent reports on potential associations between vitamin D deficiency and cardiovascular disease have highlighted its role in this system. A focus over the previous decade has been to better understand the mechanisms behind vitamin D regulation and the pathophysiology associated with suboptimal vitamin D levels. Vitamin D deficiency is highly associated with the incidence of cardiovascular diseases, even when considering other well-known risk factors. In this process, the renin-angiotensin system is disrupted, and hypertension and endothelial dysfunction contribute to the risk of cardiovascular disease. Likewise, clinical outcomes upon the normalization of vitamin D levels have been investigated in different patient populations. It makes sense that vitamin D supplementation to improve vitamin D status among vitamin D-deficient individuals could be useful without requiring a sudden lifestyle change. This manuscript provides a brief overview of vitamin D metabolism and the vitamin D receptor. It also summarizes the current clinical research relating to vitamin D supplementation and its effects on hypertension and endothelial dysfunction in cardiovascular medicine.

The identification of the DNA structure as a double-stranded helix consting of two nucleotide chain molecules was a milestone in modern molecular biology. The DNA chip technology is based on reverse hybridization that follows the principle of complementary binding of double-stranded DNA. DNA chip can be described as the deposition of defined nucleic acid sequences, probes, on a solid substrate to form a regular array of elements that are available for hybridization to complementary nucleic acids, targets. DNA chips based on cDNA clons, oligonucleotides and genomic clons have been developed for gene expression studies, genetic variation analysis and genomic changes associated with disease including cancers and genetic diseases. DNA chips for gene expression profiling can be used for functional analysis in human eel Is and animal models, disease-related gene studies, assessment of gene therapy, assessment of genetically modified food, and research for drug discovery. DNA chips for genetic variation detection can be used for the detection of mutations or chromosomal abnormalities in cnacers, drug resistances in cancer cells or pathogenic microbes, histocompatibility analysis for transplantation, individual identification for forensic medicine, and detection and discrimination of pathogenic microbes. The DNA chip will be generalized as a useful tool in clinical diagnostics in near future. Lab-on-a chip and informatics will facilitate the development of a variety of DNA chips for diagnostic purpose.

The purpose of this study was to investigate changes in Korean meat consumption as well as meat consumption trends. During the Japanese occupation period, the supply of meat was considerably insufficient. However, meat consumption mainly in large cities has gradually increased. Especially, 'Pyeongyang cow', a specialty of Pyeongyang, started being raised as edible beef cattle in 1933. During the chaotic period following liberation from Japan, the price of meat sharply increased. However, as the meat supply stabilized, the 'beef grade system' was introduced in 1967. Since then, beef has sold according to region. During the early economic growth period of the mid-1970s, meat consumption rapidly increased, and foreign beef was first imported in 1976. The preference for beef was somewhat attenuated due to the outbreak of mad cow disease and economic slowdown of the 1990s, resulting in an increase in the consumption of pork, a replacement meat. During the recent period of economic development, meat consumption has somewhat fallen and remained low. In late 2003, with the occurrence of mad cow disease in the US, the demand for pork, and especially pork fatback, has sharply increased.

This study is to understand the architectural types and characteristics of the medical facilities during ancient period. The study is based on the research of the medical and architectural history. The medical or healthcare facilities are influenced by their social, cultural and conceptual idea, especially how they think about 'disease', 'cure' and the 'medicine'. As the results of the examination of this study can be summarized as followings. Firstly, Ancient medical facilities are classified into four types according to the ideas of 'disease' and 'cure' ; 1) God oriented facility 2) health welfare facility 3) treatment oriented facility 4) practice & educational facility. Secondly, there are three typical types of the spatial characteristics what modern hospitals have ; 1) nursing ward 2) treatment ward 3) hostel or hospice. And they are all assembled around the courtyard in common. Thirdly, their architectures are not 'designed' but 'derived' plan by reasonable other building types, and transformed by medical function. Fourthly, a consideration of the surrounding circumstances is the most important point to make the medical health facilities during ancient period.
