This study was a preliminary study to establish diagnostic criterias and treatment for Orofacial Movement Disorders. The 33 Orofacial Movement Disorder patients who were visited in the department of Oral Medicine from September, 2007 to December, 2007 were selected for this study. We analyzed the age, sex, systemic diseases, the diagnosis and the cause of the patients' chief complaints, the self-consciousness and the types of orofacial movements. The obtained results were as follows : 1. Female were predominant in orofacial movement disorders(81.82% vs 18.18%) and mean age was 78.78(56 to 87) years. 2. They almost had systemic diseases(81.82%). Hypertenstion was the most common disease(22.41%) and diabetes mellitus(17.24%), depression(8.62%), gastritis(8.62%) in turns. 3. In clinical manifestation, temporomandibular disorder was the most frequently complained symptom(33.33%), and soft tissue disease(21.57%), burning mouth syndrome(17.65%), orofacial movement itself(15.69%), diffuse orofacial pain(6명, 11.76%) in turns. 4. Most orofacial movement disorders are idiopathic(72.73%), and related to prosthetic treatment(24.24%), related to antidepressant medication(3.03%) in turns. 5. The jaw-closing type was the most common type of orofacial movement disorders, and lateral type(33.33%), jaw-opening types(16.67%) in turns. 6. There were more patients who did not conscious of their orofacial movements than those who did.(54.55% vs 45.45%). In conclusion, dentists must be consider the orofacial movement disorders in patients who have orofacial pain. Also, dentists should obtain a proper history and perform a clinical examination to avoid misdiagnosis and inappropriate, irreversible treatment.

Breakthrough cancer pain is a transient exacerbation of pain that occurs despite relatively well controlled background pain with around-the-clock analgesia. It is highly prevalent in patients with cancer pain, with an overall prevalence of 70~90%. Breakthrough cancer pain has several negative effects on quality of life, including a decrease in functional status and social relationship, and higher incidence of anxiety/depression. It also places a detrimental burden on their families, society, and the healthcare system. According to the pathogenic mechanism, breakthrough cancer pain is classified into two categories: idiopathic (or spontaneous) pain and incident pain. Episodes of breakthrough cancer pain have typical characteristics, including rapid onset (5~10 min), severe intensity, and short duration (30~60 min). However, there are some variations in timing and severity of pain among patients and episodes. Therefore, a thorough assessment of pain episodes is needed and management plan must be individualized to provide optimal treatment. Several immediate-release formulations such as oxycodone, morphine, and hydromorphone are widely used despite relatively slow onset of action. Recent studies have shown that transmucosal fentanyl preparations were effective for faster control of breakthrough pain. We hope to improve management of breakthrough cancer pain with more efficient analgesics in line with currently available evidence.

This study compared the effect of different types of sounds(no sounds, sounds of nature, music, and sounds of children playing) on profile of mood states(POMS) in a healing forest. Data were collected from 231 respondents selected from among visitors to the 'Healing Field' in 'Jangseong Chukryongsan Pyeonbaek Healing Forest' in October, 2012. Each respondent was exposed to one type of sound. The results showed that there were differences in POMS among the different sound treatment groups. Sounds of children playing showed negative effects on POMS. Unexpectedly, however, sounds of nature and musical sounds had no effects on POMS. These tendencies were consistently found not only for total mood disturbance score (TMDS) but also for POMS by factors (i. e. tension, anger, vigor, fatigue, confusion, depression). Perceived crowding level was positively correlated with TMDS(r=0.568) and POMS by factors (range: r=0.331 - 0.571). This paper discusses the research results and suggests several managerial implications.

Purpose: The purpose of this study was comparing the efficacy of passive irrigation (PI) and passive ultrasonic irrigation (PUI) for ability to remove debriment of canals. Materials and Methods: Mandibular premolars were decoronated and standardized to 16 mm length. After root canal enlargement and half separating longitudinally, standardized groove of 4 mm length, 0.2 mm width and 0.5 mm depth were formed on the dentin wall of one half. Three depressions in the canal wall of the opposite half, 0.3 mm in diameter and 0.5 mm in depth, were formed. After each groove and depression was filled with dentin debris, two sections of each half were reassembled using impression putty material. In group 1 the canals were irrigated with 2.5% NaOCl by PI. In group 2 the canals were irrigated with 2.5% NaOCl by PUI. Before and after root canal irrigation, the root canal wall of the section was taken with a microscope and a digital camera as images. The amount of dentin debris remaining in grooves and depressions was assessed using a scoring system. Results: There was no significant difference between PI and PUI except for the middle 1/3 of the root canal (P = 0.004). Conclusion: At the middle 1/3 of the root canal, PUI removed more dentine debris than PI. But the removal efficiency of dentin debris is not significantly different between the PUI and PI at the apical area of root canal in mandibular premolars.

The monoamine oxidase (MAO, EC 1.4.3.4) plays a central role in the metabolism of many amines including the neurotransmitter monoamines. MAO is a flavoprotein found exclusively in the mitochondrial outer membrane, occuring in the MAO-A and MAO-B subtypes. MAO-A deaminates serotonin and noradrenaline much better than phenethylamine (PEA) or benzylamine (BA), and is preferentially inhibited by clorgyline, whereas MAO-B prefers PEA and BA as substrates and is preferentially inhibited by deprenyl. MAO inhibitors were among the first drugs used in the treatment of depression, and it is known to be the inhibition of MAO-A which is important for the antidepressant effect of MAO inhibitors. For the purpose of evaluating MAO inhibitory activities from natural resources, three kinds of edible mushrooms were screened by tracing the inhibitory activities against rat brain mitochondrial MAO-A, utilizing serotonin as a substrate and rat liver mitochondrial MAO-B utilizing benzylamine as a substrate. Among the tested mushrooms, Ganoderma lucidium and Lentinus edodes showed the weak inhibitory activities against MAO-B.

Fluoxetine is used widely as an antidepressant for the treatment of cancer-related depression, but has been reported to also have anti-cancer activity. In this study, we investigated the cytotoxicity of fluoxetine to human gastric adenocarcinoma cells; as shown by the MTT assay, fluoxetine induced cell death. Subsequently, cells were treated with 10 or 20 µM fluoxetine for 24 h and analyzed. Apoptosis was confirmed by the increased number of early apoptotic cells, shown by Annexin V- propidium iodide staining. Nuclear condensation was visualized by DAPI staining. A significant increase in the expression of cleaved PARP was observed by western blotting. The pan-caspase inhibitor Z-VAD-FMK was used to detect the extent of caspase-dependent cell death. The induction of autophagy was determined by the formation of acidic vesicular organelles (AVOs), which was visualized by acridine orange staining, and the increased expression of autophagy markers, such as LC3B, Beclin 1, and p62/SQSTM 1, observed by western blotting. The expression of upstream proteins, such as p-Akt and p-mTOR, were decreased. Autophagic degradation was evaluated by using bafilomycin, an inhibitor of late-stage autophagy. Bafilomycin did not significantly enhance LC3B expression induced by fluoxetine, which suggested autophagic degradation was impaired. In addition, the co-administration of the autophagy inhibitor 3-methyladenine and fluoxetine significantly increased fluoxetine-induced apoptosis, with decreased p-Akt and markedly increased death receptor 4 and 5 expression. Our results suggested that fluoxetine simultaneously induced both protective autophagy and apoptosis and that the inhibition of autophagy enhanced fluoxetine-induced apoptosis through increased death receptor expression.

The oriental medicine based on the traditional Chinese medicine has developed characteristically according to the history and racial character respectively; China, Korea and Japan. Japan, among these nations, has accepted western medicine earlier than other nations and has tried to compare western and oriental medicine and combine them. In Japanese traditional medicine, it is characteristic that the old medical classics focusing on Sanghannon (傷寒論) and Geumgyeyoryak(金?要略) has developed The recent tendencies of clinical medicine and researches in Korean oriental medicine are mostly about the study of oriental medicine in view of western medicine and the combination of western and oriental medical treatment like Japan. But the study on the Japanese oriental medicine hasn't so far been tried before in Korea. From now on, we should not overlook that a more interest on Japanese oriental medicine will be very useful. Therefore we have surveyed the background of its origin and the process of development of the theory of ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$. What we wish to show in this paper is to provide a source for the basic understanding by explaining a fundamental theory of physiology and pathology of Japanese oriental medicine. Concepts of ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$ suggested by Nangai Yoshimashi in 1792 is the way of thinking that the circulation of 3 factors- ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$ nourish human body. Among these 3 factors, if Qi does not function smoothly, it causes the condition of a disease like Qi-deficiency, imbalance of Qi-distribution or Qi-depression and stasis; in Blood's case, deficiency of Blood and Blood stasis; and as for Body Fluids, stasis of Body Fluids. In the recent trend of study, there's a try to combining the western and oriental medicine, Qi is considered as psychoneurotic system, Blood as circulatory and endocrinologic system and Body Fluids as immunologic system.

Objectives: The purpose of this article was to evaluate the health related quality of life (HRQoL) of cancer survivors and to identify its predictors according to gender. Methods: The research was conducted with the data for 203 (cancer survivors?) taken from the 6th wave of the Korea National Health and Nutrition Examination Survey and the EQ-5D index score was used for the measurement of the health-related quality of life (HRQoL). The independent variables inluded socio-demographic data, health related factors (survival duration, disability, subjective health recognition), and psychosocial factors (stress, unmet medical needs). The data were analyzed by the t-test, ANOVA, and hierarchical multiple regression analysis. Results: the HRQoL of the female cancer survivors was significantly worse than that of the males in terms of their mobility, usual activities, pain/discomfort and anxiety/depression quality of life. The only statistically significant factor affecting the HRQoL of the male cancer survivors was their subjective health recognition. In the case of the female cancer survivors, the statistically significant factors were their age, subjective health recognition and unmet medical needs. Conclusions: the results of this study showed a different pattern of predictors according to the gender of the cancer survivors. Therefore, gender should be considered when assessing and addressing the individual care needs of cancer survivors, in order to obtain optimal treatment outcomes.

Sertraline HCl, (1S-cis)-4-(3, 4-dichloro-phenyl)-1, 2, 3, 4-tetrahydro-N-methyl-l-naphthalenamine hydrochloride, is a potent and selective serotonin reuptake inhibitor which is used in the treatment of depression and obsessivecompulsive disorders. The purpose of the present study was to evaluate the bioequivalence of two sertraline HCl tablets, Traline tablet (Myungin Pharm. Co. Ltd.) and Zoloft$^{(R)}$ tablet (Pfizer Inc.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The in vitro release of sertraline from the two sertraline HCl formulations was tested using KP VIII Apparatus II method with various dissolution media. Twenty four healthy Korean male volunteers, $23.50{\pm}1.74$ years in age and $64.09{\pm}7.10\;kg$ in body weight, were divided into two groups and a randomized $2{\times}2$ crossover study was employed. After a single tablet containing 50 mg as sertraline HCl was orally administered, blood samples were taken at predetermined time intervals and the concentrations of sertraline in serum were determined using an online columnswitching HPLC method with UV/Vis detection. The dissolution profiles of two formulations were similar in all tested dissolution media. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated, and computer programs (Equiv Test and K-BE Test) were utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and un-transformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, Zoloft$^{(R)}$ tablet, were 0.04, 3.26 and -1.29% for $AUC_t$, $C_{max}$, and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log0.8 to log1.25. Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Traline tablet was bioequivalent to Zoloft$^{(R)}$ tablet.

Trigeminal neuralgia is defined as "a sudden, usually unilateral, brief stabbing recurrent pain in the distribution of one or more branches of the fifth cranial nerve" by the International Association for the Study of Pain(IASP). Trigeminal neuralgia is classified as an idiopathic trigeminal neuralgia with no apparent cause and a symptomatic trigeminal neuralgia which is caused by a structural lesion such as brain tumor. Over 80% of the tumors are meningioma, acoustic neuroma, and epidermoid tumors. Symptomatic trigeminal neuralgia can not be excluded even if old-aged patient does not have abnormal neurologic sign and symptom, and good response to pharmacotherapy. Therefore, initial examinations such as MRI or CT are essential to exclude symptomatic trigeminal neuralgia. When compared with CT, MRI, especially gadolinium enhanced MRI, has an increased sensitivity in the detection of intracranial lesions. The most effective medical treatment of trigeminal neuralgia is carbamazepine. The most common side effects of carbamazepine include drowsiness, dizziness, unsteadiness, nausea, anorexia. Hepatotoxicity, bone marrow depression are the most feared side effect of carbamazepine therapy but occurs rarely. It require periodic complete blood cell counts as well as hepatic and renal function tests. It has been recommended that complete blood cell counts is done every 2 weeks for the first 2months and then quaterly thereafter. Oxcarbazepine can be used if neutropenia occurs.
