  • Background: Mitochondrial heteroplasmy, the co-existence of different mitochondrial polymorphisms within an individual, has various forensic and clinical implications. But there is still no guideline on the application of massively parallel sequencing (MPS) in heteroplasmy detection. We present here some critical issues that should be considered in heteroplasmy studies using MPS. Methods: Among five samples with known innate heteroplasmies, two pairs of mixture were generated for artificial heteroplasmies with target minor allele frequencies (MAFs) ranging from 50% to 1%. Each sample was amplified by two-amplicon method and sequenced by Ion Torrent system. The outcomes of two different analysis tools, Torrent Suite Variant Caller (TVC) and mtDNA-Server (mDS), were compared. Results: All the innate heteroplasmies were detected correctly by both analysis tools. Average MAFs of artificial heteroplasmies correlated well to the target values. The detection rates were almost 90% for high-level heteroplasmies, but decreased for low-level heteroplasmies. TVC generally showed lower detection rates than mDS, which seems to be due to their own computation algorithms which drop out some reference-dominant heteroplasmies. Meanwhile, mDS reported several unintended low-level heteroplasmies which were suggested as nuclear mitochondrial DNA sequences. The average coverage depth of each sample placed on the same chip showed considerable variation. The increase of coverage depth had no effect on the detection rates. Conclusion: In addition to the general accuracy of the MPS application on detecting heteroplasmy, our study indicates that the understanding of the nature of mitochondrial DNA and analysis algorithm would be crucial for appropriate interpretation of MPS results.

  • 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.

  • The Dryness and the Dampness is the congential nature. the Water and Fire is the acquired action. the skin is related to the physiological function of the lung, so the skin is the domain of the lung. the lung belongs to the dryness-metal(燥金). And the Dryness and the Dampness in the six pathogenic factors exert a important pathogenic influence upon the skin. Psoriasis is a chronic skin condition charactered by red, silver scaly patches in the affected areas, it is caused by excessive growth of the top layer of the skin(epidermis). Scalp psoriasis affects at least two thirds people who have psoriasis. Generally, the scalp will have plaque psoriasis characterized by elevated, inflamed, lesions covered with silvery white scales. The lesion of psoriasis is head, elbow and knee that are yang-channels in Oriental medicine. The syndrome falls with in the purview of the dryness-metal(燥金). In time, psoriasis takes a turn for the worse in the winter season. In space, many of people in comparison to the average in the world have psoriasis in high latitude that is dry and cold, for instance, the Scandinavian peninsula. Deficiency of yin-fluid and blood course often the dryness-syndrome, for instance, psoriasis, etc. So psoriasis is one of the dryness-syndrome in Oriental medicine.

  • Traditionally, Korean Medicine put emphasis on the treatment and health-preserve method that corresponds with circulation of nature. And acupuncture is no exception to this rule. In "Hwangjenaegyeong(黃帝內經)", some chapters present method that is changed according to the seasons. Among the chapters, there are some difference, but we can find a general theory. In spring, Yanggi(陽氣) is coming out but not strong and cannot diffuse. so the Yanggi(陽氣) hang up the middle of outer layer. Therefore, we can take some acupoints around the muscle interspace[分腠] or tiny branches of Meridian[孫絡]. In summer, Yanggi(陽氣) flourish and boil all around of the outer layer. So, we can take some acupunctural points from skin to the yang-meridian. In both fall and winter, five su point[五輸穴] make up almost of point. in fall, yanggi begin convergence. we can remove the Eum-pathogen[陰邪] and help the normal convergence by using Stream point[腧穴], River point[經穴] and Sea point[合穴]. In winter, Eum surround so solidly that the neo Yanggi(陽氣) cannot come out. So, we can break the yin by using Well point[井穴] and make be strong by Spring point[滎穴]. If we Study the method that correspond with the seasonal circulation more, we will be able to treat diseases more minutely.

  • 1. Objectives The purpose of study is to find Lee Je-Ma's thoughts about Great Absolute-Mind in his writings. 2. Methods the concept of Lee Je-Ma's Great Absolute-Mind versus preexisted Great Absolute-Mind is compared and analysed in this study. 3. Results and Conclusions (1) Lee Je-Ma composed his Great Absolute-Mind based on its concept of the science of divination, Confucianism and medicine. However his Great Absolute-Mind is rooted in preexisted meaning, it was disputed desides the controversy between the science of divination, Confucianism and medicine. For this reason, Lee Je-Ma's Great Absolute-Mind is such an originative concept unable to be explained with a simple substitution this concept for the preexisted one of the science of divination, Confucianism and medicine. (2) Lee Je-Ma's Great Absolute-Mind is the human being itself and it can include the humanity from human being itself. (3) There are not only physical meaning of heart but also abstract metaphysical concept of heart included in Lee Je-Ma's Great Absolute-Mind. (4) The talent for comprehending principles is organically connected with the ability to attain their will. And the talent and ability is devided into Two Modes(兩儀) like Mind & Body(心身), Perception & Action(知行) and Nature & Emotion(性情). (5) The supervision of Lee Je-Ma’s Great Absolute-Mind affects physical part of body as well as spiritual part and is not devided into two but one. (6) The source of the supervision is rooted on Lungs Spleen liver Kidney(肺脾肝腎), Sasang(四象), even though it exists in the Great Absolute-Mind. So Sasang(四象), which is Lungs Spleen Liver Kidney(肺脾肝腎), is organically related to the Great Absolute-Mind in its effect and origin.

  • In this study, we considered the usecase of formulas containing either Fritillaria Bulb (川貝母) or Fritillaria Thunbergii Bulb (浙貝母). These two medicinal materials are distinguished in the Korea Pharmacopoeia and circulating the market separately. But only term "貝母" is traditionally written for describing formulas, and the proper material will have to be determined by a subjective point of view. So, we have comparatively studied the nature, flavor, meridian entry, effect and indication of two materials first. Then we have chosen 54 formulas that "貝母" was used as a primary material from the Donguibogam and the Bangyachappyun, and we have compared effects, indications of two materials and indication of 54 formulas. Finally, we have suggested proper materials for each formula by referring the results above and sentences, which is explaining formulas and the roles of materials in the combination for treatment. The analysis showed that Fritillaria Bulb is proper to 15 formulas, Fritillaria Thunbergii Bulb is proper to 31 ones. This number is 85.2% of 54 formulas and this result shows that we need to distinguish between two materials for "貝母" in the formulas from old traditional literature. For the rest 8 formulas (14.8%), we could not analyze which material is proper or not.

  • Mycoplasma pneumioniae has a unique genomic composition, cellular biology, and a fastidious nature as the smallest cell-free living organism that lacks a cell wall. Previous studies have suggested that a clinical manifestation of a M. pneumoniae infection is a consequence of a host immune response, particularly involving cellular immunity. Adenosine deaminase (ADA) is the main T-lymphocyte enzyme, and its activity is high in diseases where cellular immunity is stimulated. Therefore, its activity is useful for diagnosing a tuberculous pleural effusion. A pleural effusion is found in 5-20% of Mycoplasma pneumonia patients. However, there are few reports of high ADA activity in a mycoplasmal pleural effusion. Here we report a case of Mycoplasma pneumoniae infection established by a polymerase chain reaction and serologic tests, accompanying high ADA activity in a pleural effusion.
