Restricted supply of nutrients may affect genes at the molecular level as well as physiological functions. Understanding the cellular responses during starvation is necessary for developing strategies to reduce damage caused by starvation stress. After 1 h of starvation, Got1 gene expression was increased but its expression returned to the normal state after 24 h. Mat1 gene expression continuously increased with starvation from 1 h until 24 hr. Rats starved for 1-3 days showed significant changes in expression of the Got1 and Mat1 genes, which were significantly reduced in the cerebral cortex and cerebellum. In the lung, gene expression was increased by starvation for 1-2 days but decreased on the third day. No differences were observed in gene expression in the heart. Strong Got1 lung gene expression was seen in the starvation group one day after restoration of the food supply. Muscle mass was significantly reduced at the start of starvation and remained the same after two days of starvation and one day after the food supply was restored. The Mat1 gene expression did not change. The Got1 was induced by NaCl and showed strong expression in the lung and the thymus, but the apparent decrease of the remaining changes were not observed in male rats. The Mat1 gene was not as sensitive as the Got1 gene to induction by NaCl. However, differences in gene induction by NaCl were evident between males and females, indicating that diet control of gene expression is associated with hormones.
Objective; Antistress effect of Korean red ginseng (RG) on postmenopausal women with severe climacteric syndrome (CS) were evaluated from the viewpoint of traditional KAMPO-medicine and Western medicine. Methods; All patients with CS were treated with daily oral administration of 6g RG for 30 days. Nine patients with CS were evaluated with the use of diagnostic scores for KI-deficiency (deficiency of vital energy) and OKETSU (blood stagnation) syndrome from the viewpoint of KAMPO-medicine. In the same patients with CS, peripheral blood levels of ${\beta}$-endorphin and total plasminogen activator inhibitor-1 (t-PAI-1) were measured before and after treatment with RG. In another group, 12 patients with CS, psychological test using CMI, STAI and SDS were performed from the viewpoint of Western medicine. Stress related hormones, such as ACTH, cortisol and DHEA-S in those 12 patients with CS were also measured before and after treatment with RG. Results; KI-deficiency score and OKETSU score in patients with CS were significantly (p<0.001) higher than those in patients without CS. After treatment with RG, both scores were markedly (p<0.001) decreased compared to before treatment with RG. ${\beta}$-endorphin levels in patients with CS were significantly (p<0.05) higher than those in patients without CS. Total PAI-levels in patients with CS were increased before treatment with RG. No significant difference, however, were observed between patients with and without CS. After treatment with RG, both levels of ${\beta}$-endorphin and total PAI-1 in patients with CS were significantly (p<0.001 and p<0.05, respectively) decreased compared to before treatment with RG. CMI and STAI scores in patients with CS were significantly (p<0.05) higher than those in patients without CS. SDS scores in patients with CS were also markedly (p<0.00l) higher than in those without CS. After treatment with RG, all scores decreased within normal range. DHEA-S levels in patients with CS were about a half of those without CS. Consequently, cortisol/DHEA-S (C/D) ratio was significantly(p<0.001) higher in patients with CS than in those without CS. Although the decreased DHEA-S levels were not restored to the levels in patients without CS, the C/D ratio decreased significantly (p<0.05) after treatment with RG. Conclusion; Reinforcement of vital energy and improvement of stagnant blood circulations by oral administration of RG were elucidated from the viewpoint of traditional KAMPO-medicine. From the viewpoint of Western medicine, effect of RG on postmenopsusal women with CS seemed to be brought about in part by not only an improvement of psychoneuroendocrine dysfunctions but also an amelioration of blood coagulation systems.

Childhood psychic trauma appears to be a crucial factor in the development of serious disorders both in childhood and in adulthood. Traumatized children show strong tendency to revisualize or re-feel a traumatic events. Play and behavioral reenactments are frequent manifestations of both the single blow and the long-standing traumas in childhood. Those children who suffer the results of single, intense terror appear to exhibit detailed memory, retrospective reworkings and misperceptions. In long-standing or repetitive trauma, children would show psychic numbing, self-hypnosis, dissociation and rage. Child's brain is undergoing critical and sensitive periods of differentiation. During this time, developing central nervous system is exquisitely sensitive to stress. Stressor-activated neurotransmitters and hormones can play major roles in neurogenesis, migration, synaptogenesis, and neurochemical differentiation. Internal opiate system operates in some trauma and causes the victim to fail to respond, to avoid, to shut off feelings. Evidence is also accumulating in traumatology that dysfuntion of locus coeruleus and ventral tegmental neucleus system leads to catecholamine receptors hypersensitivity. This change result in hypervigilance, increased startle, affective lability, and increased autonomic nervous system hyperreactivity. Another site of action of trauma on the brain is hypothalamic-pituitary-adrenal axis. Individuals with PTSD do not have enough cortisol to halt the alarm reaction. When children are exposed to long-standing extreme events, massive attempts to protect the psyche and to preserve the self are put into gear. These developmental traumas mobilize various kinds of defense mechanisms. Massive denial, dissociation, self anesthesia, identification with aggressor and aggression turned against the self often lead to profound character changes in the youngsters.
We know that humans are able to live comfortably when there is a balance between the living environment that surrounds us and us. Clothing, one of the necessities of life, serves a dual purpose of functioning as protection for the body as well as providing visual satisfaction, and so is the most effective bonding mechanism. A different type of comfort that has been provided through industrialization and advancements in technology has resulted in pollution problems in the environment, and it has reached a point of seriously thinking about its effects. The biggest problems in environmental pollution are air pollution and waste disposal, and something that cannot be ignored is that environmental hormones and harmful heavy metals have been discovered in the synthetic dyes used in the clothing product, and not only are they harmful to the body, but they also have adverse effects on skin allergies such as atopic dermatitis. Its effects on clothing, especially underwear and baby products, can become a serious issue. The use of natural vegetable dye can be considered the basis for the traditional Korean dyeing process, however not all natural dyeing process can be thought of as traditional Korean dyeing. This is because natural dyeing used to be the most common method of dyeing before synthetic dyes came along and became the dye of choice for most clothing. Natural dyes are beneficial to the body, and the nature colors, achieved from the natural materials, relieve eye strains as well as have a healing effect for people who are suffering from psychological instability such as stress. However, the use of mordant in order to increase the fastness and get better color effects can lead to even more damage to the environment, and it cannot be a dyeing method that is good for the body. Traditional natural dyeing is different from regular natural dyeing because it uses colors that the Korean people can identify with and applies specific methods in order to achieve those colors. Even though experimental study with dyestuff and practical use of the dyeing methods for traditional Korean dyeing has been started(Soh, H., 1983) and has been ongoing, it is still not easy for regular people to use the method on their own. At the present time, natural dye materials are getting made and sold more than ever, but there is a lot of confusion among consumers regarding the difference between traditional Korean dyeing and natural dyeing, as companies are using the two terms interchangeably to market their natural dye products. So getting a better understanding of the characteristics of traditional Korean dyeing and traditional colors should be considered first priority at this time. The purpose of this thesis is to study the traditional Korean view of color, which developed the culture of traditional dyeing in Korea, and the characteristics of traditional Korean dyeing, a method that pursued achieving Korea's color through natural dyeing.
There are many causes of oral mucosal diseases, so accordingly, there are various treatments available. The most commonly used agents include adrenocortical hormones, antifungals, antivirals, antibacterials, and immunosuppressants. However, it must also be noted that improving oral hygiene and nutrition, and reducing stress are effective in symptom relief. Furthermore, patients with existing diseases of the oral mucosa should avoid behavior that may cause an increase in pain. Unfortunately, many patients are unaware of the activities that may lead to increased pain and therefore do not avoid these activities. The aim of this study was to investigate and analyze the behavior of patients with oral mucosal disease with regard to activities that led to increase pain. This cross-sectional study was performed on a sample of patients with oral mucosal disease selected from the Oral Medicine Clinic of the Pusan National Hospital during March to August 2013. These patients were randomly selected. From a total of 479 patients, 116 patients with mucosal disease were selected and 73 fully completed questionnaires were included in the analysis. Data were collected by using self-completed questionnaires. The results were as follows: Mean score of Question 13 (Not smoking) is $2.47{\pm}1.11$. Mean score of Question 11 (Not drinking alcohol or not using mouthwash containing alcohol) is $2.22{\pm}1.15$. The other questions resulted in scores lower than 1.5. The answers to the questions were scored according to the following assigned numerical values: not keeping = score of 0; little keeping = score of 1; often keeping = score of 2; always keeping = score of 3. In conclusion, patients with oral mucosal diseases unknowingly engage in activities that result in an increase in pain. Therefore, they need to be educated about how to behave to protect oral mucosal lesion.

The primary cilium protrudes from the cell body like a bio-antenna that has many receptors, channels and signaling molecules to sense and response to external stimuli. The external environment such as ultraviolet irradiation, temperature, humidity, gravity and shear stress always influences skin. Skin responds to external stimuli and differentiates by making melanin, collagen and horny layer. Ciliogenesis participates in developmental processes of skin, such as keratinocyte differentiation and hair formation. And it was reported that skin pigmentation was inhibited when ciliogenesis was induced by sonic hedgehog-smoothened-GLI2 signaling. When skin is exposed to ultraviolet irradiation, alpha-melanocyte stimulating hormones (${\alpha}$-MSH) increase melanin synthesis through activation of the cAMP pathway in melanocytes. We observed that ${\alpha}$-MSH and cAMP production inducers inhibited ciliogenesis of melanocytes. Therefore, we thought that regulation of ciliogenesis is potential candidate target for the development of agents to treat undesirable hyperpigmentation of skin. As a result, we found out that an ethanol extract of Glycyrrhiza glabra (EGG) root and 3,4,5-trimethoxy cinnamate thymol ester (TCTE, Melasolv) significantly inhibit melanin synthesis of normal human melanocyte by inducing primary cilium formation. This study proposed new theory to regulate skin pigmentation and cosmetic components for skin whitening.
Precise and detailed clinical research and evaluation based on objective standards are imperative factors in securing reliability of a clinical test. Built on this principle, this clinical test has been conducted during the period between March 1999 and March 2000 dealing with 31 outpatients treated with ShiHo-GuizhiTang or ShiHo-GuizhiTang modify and ShiHo-GuizhiTang mixed prescriptions at the Sung-bo ORIENTAL MEDICAL CLINIC. A variety of information relating to those patients has been collected and analyzed under such criteria as precise diagnoses and their clinical effectiveness. The analysis was duly based on "The theory of cold syndrome". Then, the 31 patients' individual clinical information was compared one another by breaking down the results into sub-categories including gender, age, disease, main symptom, blood pressure, pulse beats, syndrome of abdomen, treatment period, modify and mixed prescription, and evaluation. The result of this clinical test can be summarized as follows: First, ShiHo-GuizhiTang appears to be more frequently prescribed in the case of female patients than in the case of male patients despite the fact that it does not necessarily need to be applied only to female. In addition, the numbers of prescriptions of ShiHo-GuizhiTang in the two age groups consisting of elementary school children and economically active adults respectively were the highest among other age groups. Second, ShiHo-GuizhiTang proved to be most effective in treatment for respiratory ailments and arthritis. Third, ShiHo-GuizhiTang brought down blood pressure of hypertension patients and at the same time benefited patients with normal or lower-than-normal blood pressure who were vulnerable to diseases due to low disease-resistance. Fourth, ShiHo-GuizhiTang was effective in the case of frequent pulse(rapid pulse) and thereby indicating the fact it carries Taiyang superficies syndrome. 지맥 arises from suppressed immune responses owing to adrenocortical hormones. ShiHo-GuizhiTang controls and revitalizes those suppressed immune systems which stem from slow pulse and, as a consequence of that process, helps them return to normal condition of pulse. Fifth, from the standpoint of syndrome of abdomen, feeling of obstruction in the epigastrium serves as an important standard in the process of diagnosing diseases and evaluating effectiveness of treatments. Sixth, according to the results of the clinical test with the 31 patients, a total of 81 percent of test subjects benefited from the treatment. The figure is the sum of 52 percent of I-class (both main symptom and accompanying symptoms had been eliminated) and 29 percent of II-class (part of main symptom and accompanying symptoms had been eliminated) respectively. All told it is safe to say that ShiHo-GuizhiTang can elect to be a viable clinical treatment. In conclusion, it is estimated that this clinical study has drawn up guidelines for objective diagnostic standards and evaluation on specific treatments' effectiveness. This will lead to more general application of ShiHo-GuizhiTang. On top of that, this study could also provide an opportunity to stress the significance of ShiHo-GuizhiTang and ShiHo-GuizhiTang modify and ShiHo-GuizhiTang mixed prescriptions as an alternative treatment for collagen disease which comes from environmental degradation and pollution.
Objective; Antistress effect of Korean red ginseng (RG) on postmenopausal women with severe climacteric syndrome (CS) were evaluated from the viewpoint of traditional KAMPO-medicine and Western medicine. Methods; All patients with CS were treated with daily oral administration of 6g RG for 30 days. Nine patients with CS were evaluated with the use of diagnostic scores for KI-deficiency (deficiency of vital energy) and OKETSU (blood stagnation) syndrome from the viewpoint of KAMPa-medicine. In the same patients with CS, peripheral blood levels of $\beta$-endorphin and total plasminogen activator inhibitor-1 (t-PAI-1) were measured before and after treatment with RG. In another group, 12 patients with CS, psychological test using CMI, STAI and SDS were performed from the viewpoint of Western medicine. Stress related hormones, such as ACTH, cortisol and DHEA-S in those 12 patients with CS were also measured before and after treatment with RG. Results; KI-deficiency score and OKETSU score in patients with CS were significantly (p<0.001) higher than those in patients without CS. After treatment with RG, both scores were markedly (p<0.001) decreased compared to before treatment with RG. ${\beta}-endorphin$ levels in patients with CS were significantly (p<0.05) higher than those in patients without CS. Total PAI-I levels in patients with CS were increased before treatment with RG. No significant difference, however, were observed between patients with and without CS. After treatment with RG, both levels of ${\beta}-endorphin$ and total PAI-l in patients with CS were significantly (p<0.01 and p<0.05, respectively) decreased compared to before treatment with RG. CMI and STAI scores in patients with CS were significantly (p<0.05) higher than those in patients without CS. SDS scores in patients with CS were also markedly (p<0.001) higher than in those without CS. After treatment with RG, all scores decreased within normal range. DHEA-S levels in patients with CS were about a half of those without CS. Consequently, cortisol/DHEA-S (C/D) ratio was significantly (p<0.001) higher in patients with CS than in those without CS. Although the decreased DHEA-S levels were not restored to the levels in patients without CS, the C/D ratio decreased significantly (p<0.05) after treatment with RG. Conclusion; Reinforcement of vital energy and improvement of stagnant blood circulations by oral administration of RG were elucidated from the viewpoint of traditional KAMPO-medicine. From the viewpoint of Western medicine, effect of RG on postmenopausal women with CS seemed to be brought about in part by not only an improvement of psychoneuroendocrine dysfunctions but also an amelioration of blood coagulation systems.
Sleep plays an important role in maintaining overall human health. There is increasing interest regarding the impact of sleep related disorders on metabolic diseases. Obstructive sleep apnea (OSA) is a common health problem, and in the last decade, the emergence of increasing obesity rates has further led to a remarkable increase in the prevalence of OSA, along with more prominent metabolic diseases. Obesity is the strongest risk factor for OSA. However, OSA is also known to cause obesity, suggesting an interaction between OSA and obesity. Although the underlying mechanisms leading to OSA-induced metabolic diseases are probably multi-factorial and are yet to be fully elucidated, the activation of inflammation and oxidative stress and the dysregulation of appetite-regulating hormones have emerged as important pathophysiological components of metabolic dysfunction and obesity observed in patients with OSA. Here, we will review the current state of research regarding the association of OSA with metabolic diseases and the possible pathophysiological mechanisms by which OSA could lead to such diseases. This will enhance our understanding of the potential interactions between OSA and obesity and between OSA and metabolic dysfunction.
The purpose of this study was to determine the effects of photoperiod and light intensity on milk production, milk composition, hormones levels and blood metabolites indices of Korean Holstein dairy cows in automatic milking system (AMS). A total of 24 Holstein dairy cows were selected and used to four subsequent treatments for the experimental periods of 60 days. The light programs consisted of (1) Control: the natural photoperiod with 14.2 h of the light period and 9.4 h of the dark period (below 10 Lux); (2) T1: 16 h of the long day photoperiod (LDPP) with 50 Lux of light; (3) T2: 16 h of LDPP with 100 Lux of light; and (4) T3: 16 h of LDPP with 200 Lux of light, respectively. Importantly, there was a significant difference in the thurl activity of dairy cows between the different light intensity programs (p < 0.05). Milk yield was higher in T1 and T2 (40.80 ± 1.71 and 39.90 ± 2.02 kg/d, respectively) than those of Control and T3 (32.18 ± 1.51 and 35.76 ± 2.80 kg/d, respectively) (p < 0.05), but DMI was lower in T1, T2, and T3 compared to Control (p < 0.05). Also, milk fat percentage, the contents of milk fat and total solids were higher in T2 than those in the others (p < 0.05). The average daily melatonin level in milk was high to T3 (28.20 ± 0.43 pg/mL), T2 (24.62 ± 0.32 pg/mL), T1 (19.78 ± 0.35 pg/mL), and Control (19.36 ± 0.45 pg/mL) in order (p < 0.05). Also, the cortisol levels in milk and blood were lower in treatment groups than in Control (p < 0.05). The results of this study showed that it will be effective to improve the milk yield and milk composition, and to reduce the stress of dairy cows when the light conditions regulate to extend the photoperiod to 16 h at a light emitting diode (LED) intensity of 100 Lux under the AMS in dairy farm.
