Background : There has been increased global interest in traditional medicine. Ayurveda and Korean medicines are most world-widely spread as Complementary and Alternative Medicine(CAM). Objectives : This review gives an overview of basic principles and commonalities of Ayurveda, Tibetan and Korean medicine. Method : I have summarized the results of the research into the following categories: basic theoies, history, physiology and pathogenesis. Result : 1. Ayurveda is the medical science that grasps individual constitution through Tridosha, a combination of five primary elements(space, wind, fire, water, and earth), and systematically explains physiological and pathological phenomena which reveal according to the constitution. 2. The theoretical basis forming the Tibetan Medicine is the substance of phlegm, bile, and wind each of which is divided into five kinds. These physiological substances can be transformed into pathological factors when certain environment is formed. 3. Ayurveda, Tibetan and Korean medicine, three main axes of the traditional medicine arouse western medical researchers' interest by their peculiar views of the disease and the system of their medical theories. And they are expected to render services to human health. Conclusions : We can expect the potential of the approaching between Ayurveda, Tibetan and Korean medicine.

The objective of this study was to examine the effects of concentrates containing different levels of a vitamin-trace elements premix on milk yield and composition of dairy cows. The trial, which lasted 14 weeks, was conducted from January to March and used 45 multiparous Brown cows in the early phase of lactation. Cows (n = 15 per treatment) were randomly allocated to three dietary treatments: the first group (control, C-0) was fed pelleted concentrate containing background vitamins and trace elements that supplied 1.0 times cows' daily requirements; the second group were fed the same concentrate, but containing 2.5 g/kg of vitamin and trace mineral premix per kg of concentrate (C-2.5); the third group were fed the same concentrate, but containing 5 g/kg of vitamin and trace mineral premix per kg of concentrate (C-5). The daily ration included ad libitum chopped oat hay, and the cows also had 8 h/d grazing on a ryegrass (Lolium multiflorum) pasture. During the performance trial, cow milk yield was daily recorded and individual milk samples were analysed for milk composition and to determine milk renneting properties. Cows fed the intermediate premix level (C-2.5) in diet showed the highest fat-corrected milk production (p<0.05) compared to other groups. None of the milk quality parameters studied were influenced by dietary treatment, except for milk rheological parameters (rennet clotting time and curd firmness) that were positively improved in cows fed the C-2.5 diet (p<0.05). The findings from this study show that intermediate level of vitamin-trace elements premix in concentrate can be advantageously used in grazing dairy cows without negative effects on yield and quality of milk produced.

The individual differences in disease development and susceptibility have been researched primarily on the subject of genes, environment or the interaction between genes and the environment respectively. However, there have been limitations in explaining complex diseases, and the differences in health and diseases in monozygotic and dizygotic twins. Fortunately, thanks to active research on the relationship between genes and the environment, and epigenetics, there has been much progress in the understanding of body's reactions and changes. Epigenetics is referred to as a study of gene expression through the interactions of DNA methylation, chromatin's histone and the change of structure in tail, RNA editing without any change in DNA sequence. In this paper, we introduce the basic concepts and mechanisms of epigenetics. The result of the epigenetics is heritable ; can regulate gene expressions ; is reversible ; and has many variable forms depending on cell types. The influences of epigenetics occur throughout life, but it is mainly determined in utero during early pregnancies. Diseases occur or the risk rises if these influences continue after birth until adult life when problems occur in excess/lack of nutrition, environmental plasticity, or already inputted data. Therefore, there is a need for change and innovation, especially in interest and investment in health education for young women near pregnancies and correct treatment of epigenetic-related diseases.

Molecular mapping of plant genomes has progressed rapidly since Bostein et al.(1980) introduced the idea of constructing linkage maps of human genome based on restriction fragment length polymorphism (RFLP) markers. In recent years, the development of protein and DNA markers has stimulated interest for the new approaches to plant improvement. While classical maps based on morphological mutant markers have provided important insights into the plant genetics and cytology, the molecular maps based on molecular markers have a number of inherent advatages over classical genetic maps for the applications in genetic studies and/or breeding schemes. Isozymes and DNA markers are numerous, discrete, non-deleterious, codominant, and almost entirely free of environmental and epistatic interactions. For these reasons, they are widely used in constructing detailed linkage maps in a number of plant species. Plant breeders improve crops by selecting plants with desirable phenotypes. However a plant's phenotyes is often under genetic control, positioning at different "quantitative trait loci" (QTLs) together with environmental effects. Molecular maps provide a possible way to determine the effect of the individual gene that combines to produce a quantitative trait because the segregation of a large number of markers can be followed in a single genetic cross. Using market-assisted selection, plants that contain several favorable genes for the trait and do not contain unfavourable segments can be obtained during early breeding processes. Providing molecular maps are available, valuable data relevant to the taxonomic relationships and chromosome evolution can be accumulated by comparative mapping and also the structural relationships between linkage map and physical map can be identified by cDNA sequencing. After constructing high density maps, it will be possible to clone genes, whose products are unknown, such as semidwarf and disease resistance genes. However, much attention has to be paid to level-up the basic knowledge of genetics, physiology, biochemistry, plant pathology, entomology, microbiology, and so on. It must also be kept in mind that scientists in various fields will have to make another take off by intensive cooperation together for early integration and utilization of these newly emerging high-techs in practical breeding. breeding.

There are some controversies about the safety of herbal medicine. In order to examine the safety of herbal medicine, this study investigated the level of liver function test(AST/ALT) in patients taking herbal medicine for more than 6 months We checked liver function in 121 patients who took herbal medicine for more than 6 months. AST/ALT were measured before treatment and every 3 months (from 3 month to 9 month). In 121 patients taking herbal medicine for more than 6 months, mean AST level after 6 months was lower than before treatment and mean ALT level after 6 months was lower than before treatment. In 20 patients with abnormal AST/ALT before herbal treatment, 18 patients's AST/ALT changed to normal after 6 month herbal treatment. 2 patients's AST/ALT was slightly higher than normal. One woman patient met the criteria for herb-induced liver injury(HILI) with RUCAM scores 4 after taking herbal medicine for 6 months. Although her RUCAM score decreased to zero after taking herbal medicine for 9 months. This study suggests that long-term herbal medicine for 6 months or longer is very unlikely to injury liver function. Individual-specific liver damage may occur, it can be recovered.

Intrathecal drug delivery is an effective and safe option for the treatment of chronic pathology refractory to conventional pain therapies. Typical intrathecal administered drugs are opioids, baclofen, local anesthetics and adjuvant medications. Although knowledge about mechanisms of action of intrathecal drugs are every day more clear many doubt remain respect the correct location of intrathecal catheter in order to achieve the best therapeutic result. We analyze the factors that can affect drug distribution within the cerebrospinal fluid. Three categories of variables were identified: drug features, cerebrospinal fluid (CSF) dynamics and patients features. First category includes physicochemical properties and pharmacological features of intrathecal administered drugs with special attention to drug lipophilicity. In the second category, the variables in CSF flow, are considered that can modify the drug distribution within the CSF with special attention to the new theories of liquoral circulation. Last category try to explain inter-individual difference in baclofen response with difference that are specific for each patients such as the anatomical area to treat, patient posture or reaction to inflammatory stimulus. We conclude that a comprehensive evaluation of the patients, including imaging techniques to study the anatomy and physiology of intrathecal environment and CSF dynamics, could become essential in the future to the purpose of optimize the clinical outcome of intrathecal therapy.

Effects of sucrose supplement on the pattern of VFA production and microbial protein synthesis in the rumen were examined in sheep consuming basal diet of grass silage (2.5 kg fresh wt/d) that was provided in 24 equal meals each day by an automatic feeder. Four mature wethers were allocated to four experimental treatments in a 4${\times}$4 Latin square design with periods lasting 14 days. The treatments were (1) the basal diet, (2) supplemented with 150 g sucrose and 7.0 g urea, (3) 300 g sucrose and 13 g urea, and (4) 450 g sucrose and 20 g urea given as a continuous intraruminal infusion for 24 h. All infusions were given in 2 litres of aqueous solution per day using a peristaltic pump. The effect of sucrose level on rumen mean pH was significantly linear (p<0.01). There were not significant differences in the concentration of ammonia-N, total VFA and the molar proportions of acetate, propionate and butyrate with the level of sucrose infusion. The molar proportions of isobutyric acid (p<0.05) and isovaleric acid (p<0.001) were significantly reduced when the infused amount of sucrose was increased. The flow of microbial N was linearly (p<0.001) increased with sucrose and urea level. High levels of readily fermentable carbohydrate in a ration reduced the efficiency of microbial protein synthesis in the rumen. It was demonstrated that of the individual fatty acids, only the molar proportion of isovalerate showed a significant negative correlation (R2=$0.3501^{**}$) with the amount of microbial N produced and a significant positive correlation (R2=$0.2735^{**}$) with the efficiency of microbial growth.

Background: Prevalence of chronic pain and its association with demographic characteristics have been reported by different studies from different geographical regions in the world. However, data from many Middle East countries including Iran (especially southern Iran) are scare. The aim of the present study was to demonstrate the prevalence of chronic pain and its association with demographic, psychological and socioeconomic factors in an Iranian population. Methods: In this population-based survey, the target population was comprised of subjects aged 20 to 85 years residing in Jahrom, southern Iran during 2009-2011. All eligible subjects were invited to participate in the study. Before a detailed questionnaire was given; face to face interviews were done for each individual. Results: There were 719 men and 874 women with an average age of 40.5 years at the onset of the study. Among the study population, 38.9% (620/1,593) complained of chronic pain, of whom 40.8% (253/620) were men and 59.2% (367/620) were women. Foot and joint pain were observed in 31.9%. Hip and spine pain, migraine and tension headaches, heart pain, and abdomen pain were observed in 21.5%, 15.5%, 9.5%, and 8.0% of chronic pain cases, respectively. There was a significant association among the covariables age, sex, overweight, educational level, income, and type of employment with chronic pain as the dependent variable (P < 0.0001). Conclusions: Our findings show the prevalence of chronic pain and its association with demographic, psychological and socioeconomic factors. Individuals with low incomes and less education became accustomed to pain due to a lack of knowledge.

Inter-individual pharmacokinetic variation of H2-receptor antagonist is related to genetic polymorphism of CYP2C19. We investigated the frequency of CYP2C19 genetic polymorphism and the treatment duration of cimetidine by CYP2C19 genotypes in functional dyspeptic patients without definite causes who were treated with cimetidine in Korea. One hundred subjects with functional dyspepsia participated in this study from March 1, 2010 to June 30, 2011. They were tested by upper gastrointestinal endoscopy and treated for their dyspepsia with cimetidine. The single nucleotide polymorphisms (SNPs) of CYP2C19 were genotyped using the Seeplex CYP2C19 ACE Genotyping system. There were no significant differences in the demographic, clinical, or laboratory findings among the CYP2C19 subgroups which are wild type homozygote (W/W), heterozygote (W/V), and variant homozygote (V/V). The frequencies of CYP2C19 subgroups were 33 (33%) in W/W, 49 (49%) in W/V, and 18 (18%) in V/V, respectively. The mean duration of cimetidine treatment (in weeks) was the shortest in the V/V among the CYP2C19 genotypes (W/W: $5.1{\pm}1.5$, W/V: $4.0{\pm}1.7$, V/V: $2.1{\pm}0.7$; p<0.001). This study can also act as a basis for further investigation to identify the underlying genetic, epigenetic, or environmental factors in CYP2C19 enzyme activity.

To assess the effect of pinitol supplementation and strength training for two weeks on the anaerobic capacity during and after exercise, and improvement of glucose metabolism during the recovery period of muscular fatigue with repeated acute bouts of cycling exercise, a total of 24 healthy young men were recruited and randomly and equally divided into three groups; pinitol supplementation group (PSG), placebo group (PLG), and control group (CON). Using a randomized double-blinded design, subjects in PSG were provided pinitol supplement, consumed orally 1.2 g/day, and participated in the resistance exercise program and cycling exercise for two weeks. Subjects in PLG underwent the same protocol as those in PSG but consumed the same amount of placebo. No supplementation and exercise program was given to CON. Before and after the intervention, all subjects were tested for their anaerobic capacities evaluated by Wingate test twice separated by 30 min. During the test, peak anaerobic power (PP), mean anaerobic power, total work, and fatigue index were evaluated During resting and recovery, blood samples were drawn and plasma pinitol, myo-inositol, chiro-inositol, insulin, free fatty acid, glucose, and lactate levels were analyzed After two weeks, PP and relative PP of the second biking were improved from the first biking in PSG only (p<0.05). No changes were found in all other variables of Wingate test in all groups. No statistical differences between groups and pre- and post-intervention were observed in concentrations of pinitol, myo-inositol, and chiro-inositol, but pinitol concentration was higher during recovery compared to the baseline in all groups and testings (p<0.05). Lactate level during recovery was higher than the resting level, but no other blood parameters were significantly changed. In conclusion, two weeks of pinitol supplementation in conjunction with short duration of anaerobic training in healthy young men did not induce any obvious benefits in terms of anaerobic capacity and energy metabolism Individual and/or population susceptibility may be one factor responsible for adopting pinitol supplementation.
