Korean medicated diet (KMD) is not a simple combination of food and Chinese drugs, but a special carefully constructed diet made from Sasang constitutional medicines, food and condiments under the theoretical guidance of diet preparation based on differentiation of symptoms and signs of traditional Sasang medicine (TSM). It combines the functional efficacy of medicine with the delicacy of food, and can be used to prevent and cure diseases, build up one's health and prolong one's life. Korean traditional medicated diet has a long history of development. Although influenced by Chinese medicine, Korean traditional medicine has been developed into a unique system of traditional medicine that has surpassed the continental medical practice, sublimating itself into a native medical practice suitable to Korean lifestyles and physical constitutions. In the 19th century, Lee Jema's Sasang medicine (medicine of four types of energy determining the physical constitution) was introduced. It is an integration of mind and body according to the individual's physical constitution that is categorized allowing a customized method of treatment ideal for each category-making the content of Korean traditional medicated diet even richer. The characteristics of Korean medicated diet are as follows: (1) Laying stress on the wole, selecting medicated diet on the basis of differential diagnosis. (2) Suitable for prevention and treatment, outstanding in effect. (3) Good in taste, convenient for taking. KMD refers to drink and food according to certain prescriptions, by processing and cooking that can be used either for prevention and cure of diseases, or for health care and recovery. The purpose of this review is to introduce TSM and KMD based on Sasang constitutional medicines.

Brain aging is an inevitable process characterized by structural and functional changes and is a major risk factor for neurodegenerative diseases. Most brain aging studies are focused on neurons and less on astrocytes which are the most abundant cells in the brain known to be in charge of various functions including the maintenance of brain physical formation, ion homeostasis, and secretion of various extracellular matrix proteins. Altered mitochondrial dynamics, defective mitophagy or mitochondrial damages are causative factors of mitochondrial dysfunction, which is linked to age-related disorders. Etoposide is an anti-cancer reagent which can induce DNA stress and cellular senescence of cancer cell lines. In this study, we investigated whether etoposide induces senescence and functional alterations in cultured rat astrocytes. Senescence-associated ${\beta}$-galactosidase (SA-${\beta}$-gal) activity was used as a cellular senescence marker. The results indicated that etoposide-treated astrocytes showed cellular senescence phenotypes including increased SA-${\beta}$-gal-positive cells number, increased nuclear size and increased senescence-associated secretory phenotypes (SASP) such as IL-6. We also observed a decreased expression of cell cycle markers, including PhosphoHistone H3/Histone H3 and CDK2, and dysregulation of cellular functions based on wound-healing, neuronal protection, and phagocytosis assays. Finally, mitochondrial dysfunction was noted through the determination of mitochondrial membrane potential using tetramethylrhodamine methyl ester (TMRM) and the measurement of mitochondrial oxygen consumption rate (OCR). These data suggest that etoposide can induce cellular senescence and mitochondrial dysfunction in astrocytes which may have implications in brain aging and neurodegenerative conditions.

Previous studies have suggested that rice bran oil (RBO), an edible oil from the byproducts of rice milling, has anti-inflammatory effects in inflammation inducing macrophages, known as M1 subsets. Yet the effects of RBO on the counterpart M2 subsets, the "healing" macrophages, were poorly investigated to date. In this regard, recent studies on the molecular/cellular anti-inflammatory mechanisms of dietary components have demonstrated that mitochondrial respiration contributes to macrophage functioning. Therefore, the current study examined whether RBO regulates cytokine secretion by modulating mitochondrial metabolism in wound healing M2 subsets. Palm oil (PO), enriched with medium-chain fatty acids, served as a positive control. C57BL/6 mice were fed a diet containing either corn oil (CO), PO or RBO for 4 weeks, followed by purification of bone marrow-derived macrophages (BMDM) from their tibias and femurs. Cells were further polarized to M2-BMDM, and the expression of M2 marker (CD206) on cellular surfaces were not affected by dietary intervention. In addition, the secretion of anti-inflammatory cytokine (IL-10) in the culture supernatant was not affected by dietary lipids. Oxygen consumption rate, the indicator of mitochondrial respiration in M2-BMDM was not regulated by RBO intervention and PO treatment. Taken together, this study imply that RBO did not intervene both the regulation of inflammatory responses and mitochondrial respiration in M2 macrophages.

We describe a case of hyperbaric oxygen therapy (HBOt) as an adjunct to treatment of a crush injury to the hand. A 34-year-old male paramedic was involved in a motor vehicle accident and admitted for diagnosis and surgical treatment. He sustained a crush injury to his right hand and presented with significant muscle damage, including multiple fractures and dislocations, an avulsion injury of the flexor tendons, and amputation of the distal phalanx of the little finger. He underwent reconstructive surgery and received HBOt over the following days. In the following 2 months, he lost the distal and middle phalanges of the little finger and recovered hand function. Posttraumatic compartment syndrome responds well to HBOt, which reduces edema and contributes to angiogenesis, as well as promoting the cascade of healing events. High-energy trauma causes massive cell destruction, and the blood supply is usually not sufficient to meet the oxygen demands of viable tissues. Hyperbaric oxygenation by diffusion through interstitial and cellular fluids increases tissue oxygenation to levels sufficient for the host's responses to injury to work and helps control the delayed inflammatory reaction. HBOt used as an adjunct to surgical treatment resulted in early healing and rehabilitation, accelerating functional recovery. The results suggest that adjunctive HBOt can be beneficial for the treatment of crush injuries of the hand, resulting in better functional outcomes and helping to avoid unnecessary amputations.

Objectives : The rapid progress seen in the Chinese medical and pharmaceutical industries since the mid.Ming Dynasty, and the resulting surge in demand for medicinal herbs led to the emergence of dedicated medicinal herb markets. A representative example was the medicinal herb market of Qizhou (today's Anguo) in Hebei Province. This paper examines various factors that contributed to the transformation and growth of Qizhou into and as a major medicinal herb market of China. Methods : Along with the examination of geographical factors, this study attempts to link the development of Qizhou as a center for medicinal herbs trade with legends related to the Medicine Lord Temple (Yao Wang Miao), a local shrine dedicated to the mythical Medicine Kings. Results : The main argument of this study is that although the emergence of Qizhou as China's largest marketplace for medicinal herbs was significantly helped by its proximity to Beijing, a huge source of demand, as well as its convenient location easily accessible from all parts of the country, and the large herbal production from surrounding areas, the single.most important contributing factor was the body of legends attributing to this city a magical healing energy. Conclusions : The example of Qizhou may also suggest that in pre.modern eras, legends related to supernatural healing power, associated to a city or town, were as important contributing factors to its emergence and growth as a dedicated medicinal herb market as its location or ease of access.

The purpose of this study is to explore the concept spirituality and to gain understanding of nursing intervention that may improve spiritual well-being. The concept analysis framework developed by Walker and Avant (1995) was used to clarify the concept. In the study, 'Harmonious interconnectedness', 'Transcendence', 'Integrative Energy' and 'Purpose and Meaning in Life' emerged as the critical attributes of spirituality. The first attribute, 'harmonious Inter- connectedness', has three categories including intrapersonal, (self), interpersonal (others/ nature) and transpersonal (the Supreme Being). The second attribute, 'Transcendence', is defined as the ability to extend one's own self beyond the limits of usual experiences and to achieve new perspectives. This attribute is demonstrated by 'coping with situations', to 'self-healing', and 'transformation'. The third attribute of spirituality is 'Integrative Energy', which integrates all dimensions and acts as a creative and dynamic force that keeps a person growing and changing. 'Integrative Energy is also defined as an inner resource that gives a sense of empowerment. Therefore the highly spiritual person demonstrate 'inner peace', 'growing', 'inner strength,' and 'well-being'. The fourth attribute 'Purpose and Meaning in Life' represents a sense of connectedness with one's inner values and with a greater purpose in life. It is demonstrated by 'hope' and 'a powerful life'. In this study, the antecedents of the spirituality represented as 'spirit' and its potential enablers were 'Introspection/reflection', 'Interconnectedness with all living things', and an 'Awareness of a Higher-Power'. The consequences of this concept may be described as 'physical, psychosocial, and spiritual well-being'. Empirical referents of this are 'purposeful life' 'self-worth' 'hope' 'love' 'service' 'forgiveness' 'trust/belief' 'inner peace' 'self-actualization' 'religious practices' 'transformation' 'inner strength' and 'coping'. In conclusion, spirituality can be defined based on these critical attributes. Spirituality is a dynamic, integrative energy based on a feeling of harmonious interconnection with self, others and a higher power. Through it, one is enabled to transcend and to live with meaning and purpose in life.

The present study was designed to understand the basic principles of the laser system and to assess the optimal coditions of the Nd:YAG laser irradiation system in order to expand the use of the laser system in the dental field. The laser system used in this study was a pulsed-wave output type and the power level is 9 watts. The incisors of developing rats were irradiated with the laser system explained above for 0.5, 1, and 2 seconds giving energy density 71, 167, and 215 J/$cm^2$ respectively. The rats were sacrificed just after irradiation or 10 minutes and 10 days after irradiation. The specimens were examined with the stereoscope, light microscope and transmission electron microscope. The results are as follows: 1. The tissue removal efficiency (depth of the cavity formed) is increased with the energy density after Nd:YAG laser irradiation. 2. The carbonized area is increased with the energy density. Cracks and melted appearance are seen in all kinds of the energy densities. 3. The lacunae in the damaged alveolar bone by the laser irradiation were empty, while those in the newly formed bone were occupied with the osteocytes. The damaged alveolar bone was repaired by the osteoblasts and macrophages on the periphery of the bone matrix. 4. The damaged enamel was replaced by the loose connective tissues showing many kinds of cells. The ameloblasts were differntiated on the replaced loose connective tissue. 5. The damaged dentin was repaired by the irregular dentin formed by the odontoblasts differentiated from the mesenchymal cells migrated from the pulp core.

Feul-cell system consists of fuel reformer, stack and energy translator. Among these parts, slack is a core part which produces electricity directly. In order to set a stack module, fabrication of appropriate stack, design of water flow path in stack, and control of coolant are needed. Especially, water or air is used as a coolant to dissipate heat. The different temperature of each electric cells after cooling and the high temperature of the stack affect the performance of the stack, Therefore, it is necessary that the relationship between coolant, healing rate, width of slack, properties of stack, and the shape of water flow path must be understood. For the optimal design, the computational simulation by CFD-ACE has been conducted and the resulting database has been constructed.
