  • As of today, the frequency of primary lung cancer is one of the improved problems in modern medicine and is increasing rapidly year by year. This study dealed with 138 cases of primary lung cancer proved by histopathologic examination in Thoracic & Card iovascular Surgery Dept. of N.M.C. from Sept. 1966 through June 1981. The majority of patients belong to 5th and 6th decade. Ratio between male and female was 3.7: 1. Initial symptoms were cough, blood tinged sputum, hemoptysis, chest pain, dyspnea and duration of symptoms before admission was within 6 months [60%] and 12 months [78%]. Histopathologically, 64 cases [61%] of them were the squamous cell carcinoma, 21 cases [15%] were the adenocarcinoma, 20 cases [14.8%] were the anaplastic carcinoma. Fifty-six cases were resectable: 43 cases were subjected to pneumonectomy and 13 cases were to lobectomy. The remaining 82 cases were nonresectable, but exploratory thoracotomy was performed in 22 cases of them. Among 56 resected cases, 33 cases were radically operated and 17 cases were subjected to palliative operation and 6 cases were subjected to extended operation. [Concomitant pericardium resection in 1 case and concomitant chest wall resection in 5 cases]. Surgical mortality was 10.7% and causes of death were aspiration of contralateral lung, respiratory insufficiency, postop. empyema with B.P.F, cardiogenic failure. This study analysed the cancer stage between preop clinical T.N.M. stage and postop. T.N.M. stage in 78 cases; resectable 56 cases and non-resectable 22 cases.

  • 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.

  • Moyamoya disease (MMD) is a chronic, progressive, cerebrovascular occlusive disorder that displays various clinical features and results in cerebral infarct or hemorrhagic stroke. Specific genes associated with the disease have not yet been identified, making identification of at-risk patients difficult before clinical manifestation. Familial MMD is not uncommon, with as many as 15% of MMD patients having a family history of the disease, suggesting a genetic etiology. Studies of single nucleotide polymorphisms (SNPs) in MMD have mostly focused on mechanical stress on vessels, endothelium, and the relationship to atherosclerosis. In this review, we discuss SNPs studies targeting the genetic etiology of MMD. Genetic analyses in familial MMD and genome-wide association studies represent promising strategies for elucidating the pathophysiology of this condition. This review also discusses future research directions, not only to offer new insights into the origin of MMD, but also to enhance our understanding of the genetic aspects of MMD. There have been several SNP studies of MMD. Current SNP studies suggest a genetic contribution to MMD, but further reliable and replicable data are needed. A large cohort or family-based design would be important. Modern SNP studies of MMD depend on novel genetic, experimental, and database methods that will hopefully hasten the arrival of a consensus conclusion.

  • 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.

  • This study analyzed surface-chemical transitions in manufacturing process of traditional acupuncture as proposed method by Dongeuibogam. The manufacturing process of traditional acupuncture from a used iron for a long time was divided by primary medicinal herbs treatment, secondary medicinal herbs treatment and tertiary treatment using by dog meat. The traditional acupuncture research process was measured according to the characteristics and changes of the specimens at each processing step of the manufacturing process. The following devices were used to Surface analysis. Scanning electron microscopy (SEM), Energy Dispersive Spectrometer (EDS), X-ray diffraction analyzer (XRD). As a result, medicinal herbs removed impurities on the surface and raised the antibacterial effect in the manufacturing process of traditional acupuncture. Furthermore, the ingredients of medicinal herbs were coated on the surface of the iron. Dog meat influenced to prevent surface corrosion, reduce friction when the acupuncture was inserted. Although the process empirically obtained, a glimpse of the wisdom of our ancestors was revealed. These ancestral wisdom can be expected to apply today, when used in manufacturing process of a modern stainless steel acupuncture to compensate for the defective part.

  • Anxiety is one of the basic human emotions. From the evolutionary psychology point of view, it is a necessary factor for survival and prosperity of human beings that had been developed throughout time with the history of human survival and development. Anxiety plays the role of protecting one from social or physical threats. In reality, lacking of anxiety showed lots of examples of maladjustments. But the result of over-adjustment, which is overanxious disorder, is definitely disturbing one's survival and growth, and it can lead to anxiety disorder that needs to be treated. Anxiety from the evolutionary psychology point of view, started as a primary adjustment form and it evolves into various types of anxiety disorders that relates to the modern society's characters. Therefore, having the grasp of evolutionary psychology, which can be the base of treating anxiety and anxiety disorders, is very important. So from now on, studies for this aspect would need to be done as integrated and multidisciplinary studies not only by psychiatrists, but by including epidemiologists, psychologists, ecologists, biologists, and neuropsychologists. In this article, the author tried to review and explore the idea of anxiety and anxiety disorders from the evolutionary psychology point of view.

  • Purpose: This study was to explore the postnatal care experiences among first time Chinese immigrant mothers living in Korea. Methods: Data were collected by focus group interviews with 12 first time Chinese immigrant mothers utilizing 3 focus groups. After obtaining written informed consent from all participants, each session of the focus group was audio-recorded and transcribed verbatim. Data were analyzed by content analysis to identify major themes. Results: Four major themes for postnatal care experiences were extracted from the data as follows. 1) Range over traditional, modern, Korean or Chinese postnatal care, 2) Struggle with newborn care, 3) Another struggle with breastfeeding, and 4) Difficulties in becoming a mother as an immigrant. Conclusion: Based on their postpartum care experiences, it is concluded that participants requested more professional practical and individualized education/training for successful breastfeeding and newborn care. Health care providers need to develop and implement integrated support and mentoring programs that include information and peer support system for the first time Chinese immigrant mothers living in Korea. This would decrease the difficulties of becoming a mother.

  • 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.
