Objective : "Dochangbup" is one of the therapies that remove pathogenic qi[邪氣] from the Emetic Method in the Miscellaneous Disorders part of Dongeuibogam東醫寶鑑. It is, in particular, the method of treatment that removes phlegm[痰], the cause of various disorders. Method : Application of "Dochangbup" had a long history in Korea as well. The meaning and application of "Dochangbup" are mentioned in various texts from early Chosun dynasty to the post liberation. Result : In China, there are a lot of medical texts by physicians throughout Ming and Qing Dynasty, with GeZhiYuLun格致餘論 at the top of the list, dealing with the meaning and applicable scope of "Dochang" method and pharmacy of "Hacheongo霞天膏". Most of the physicians are affiliated with Dan Xi School, regarding ZhudanXi朱丹溪 as a suzerain. In "Dongeuibogam", it is mentioned that "Dochangbup" can treat various disorders caused by phlegm. Though, when there is a possibility of harming original qi[元氣] during the treatment or grave deficiency in patients, it is requested to consider tonifying while purging. Conclusion : "Dochangbup" can be applied not only to the disorders mentioned in classical medical texts, like heart pain[心痛], leg disease[脚氣], urine turbidity[小便濁], involuntary discharge of semen[遺精], cough[咳嗽], blood spitting[喀血], but also to metabolic syndrome such as obesity, hypertention and diabetes, commonly found in the modern era.

G protein-coupled receptor(GPCR) family is a cell membrane protein, and plays an important role in a signaling mechanism which transmits external signals through cell membranes into cells. Now, it is estimated that there may be about 800-1000 GPCRs in a human genome. But, GPCRs each are known to have various complex control mechanisms and very unique signaling mechanisms. GPCRs are involved in maintaining homeostasis of various human systems including an endocrine system or a neural system and thus, disorders in activity control of GPCRs are thought to be the major source of cardiovascular disorders, metabolic disorders, degenerative disorders, carcinogenesis and the like. As more than 60% of currently marketed therapeutic agents target GPCRs, the GPCR field has been actively explored in the pharmaceutical industry. Structural features, and class and subfamily of GPCRs are well known by function, and accordingly, the most fundamental work in studies identifying the previous GPCRs is to classify the GPCRs with given protein sequences. Studies for classifying previously identified GPCRs more easily with mathematical models have been mainly going on. Considering that secondary sequences of proteins, namely, secondary binding structures of amino acids constituting proteins are closely related to functions, the present paper does not place the focus on primary sequences of proteins as previously practiced, but instead, proposes a method to transform primary sequences into secondary structures and compare the secondary structures, and then detect an unknown GPCR assumed to have a same function in databases of previously identified GPCRs.

Obesity and the metabolic disorders that constitute metabolic syndrome are a primary cause of morbidity and mortality in the world. Nonetheless, the changes in the proteins and the underlying molecular pathways involved in the relevant pathogenesis are poorly understood. In this study a proteomic analysis of the visceral adipose tissue isolated from metabolically healthy and unhealthy obese patients was used to identify presence of altered pathway(s) leading to metabolic dysfunction. Samples were obtained from 18 obese patients undergoing bariatric surgery and were subdivided into two groups based on the presence or absence of comorbidities as defined by the International Diabetes Federation. Two dimensional difference in-gel electrophoresis coupled with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was carried out. A total of 28 proteins were identified with a statistically significant difference in abundance and a 1.5-fold change (ANOVA, $p{\leq}0.05$) between the groups. 11 proteins showed increased abundance while 17 proteins were decreased in the metabolically unhealthy obese compared to the healthy obese. The differentially expressed proteins belonged broadly to three functional categories: (i) protein and lipid metabolism (ii) cytoskeleton and (iii) regulation of other metabolic processes. Network analysis by Ingenuity pathway analysis identified the $NF{\kappa}B$, IRK/MAPK and PKC as the nodes with the highest connections within the connectivity map. The top network pathway identified in our protein data set related to cellular movement, hematological system development and function, and immune cell trafficking. The VAT proteome between the two groups differed substantially between the groups which could potentially be the reason for metabolic dysfunction.

Objectives : Polygoni Multiflori Radix (Jeokhasuo in Korean) is a Oriental traditional herbs widely used in East Asian countries. Overconsumption of fructose results in hypertension, dyslipidemia, obesity and impaired glucose tolerance which have documented as a risk of cardiovascular diseases. This experimental study was designed to investigate the beneficial effects of an ethanol extract from Polygoni Multiflori Radix (PMR) in high-fructose (HF) diet-induced metabolic syndrome rat model. Methods : Sprague-Dawley (SD) rats were divided into three groups; Control group, receiving regular diet and tap water, HF group, and HF + PMR group both receiving supplemented with 65% fructose (n=10), respectively. The HF + PMR group initially received HF diet with PMR (100 mg/kg/day) for 8 weeks. Results : PMR significantly prevented the metabolic disturbances such as hyperlipidemia, hypertension and impaired glucose tolerance. Chronic treatment with PMR significantly decreased body weight, fat weight and adipocyte size, suggesting a role of anti-obesity effect. PMR led to improve the hyperlipidemia through the increase in HDL cholesterol level as well as the decrease in triglyceride and LDL cholesterol level. In addition, PMR suppressed adhesion molecules and endothelin-1 (ET-1) expression in aorta resulting in the decrease of hypertension. In muscle tissue, PMR significantly recovered the HF-induced insulin resistance through increase of insulin receptor substrate-1 (IRS-1), p-$AMPK{\alpha}1/2$, and p-Akt expression. PMR improved HF-induced metabolic disorders and its action was caused by energy metabolism-mediated insulin signaling activation. Conclusions : These results demonstrate that PMR may be a beneficial therapeutic for metabolic syndrome through the improvement of hyperlipidemia, obesity, insulin resistance and hypertension.

Negative myoclonus (NM) is a shock-like jerky involuntary movement caused by a sudden, brief interruption of tonic muscle contraction. NM is observed in patients diagnosed with epilepsy, metabolic encephalopathy, and drug toxicity and in patients with brain lesions. A 55-year-old man presented with NM in both his arms and neck. He has taken medications containing tramadol at a dose of 80-140 mg/day for 5 days due to common cold. He had no history of seizures. Acute lesions were not observed during magnetic resonance imaging, and abnormal findings in his laboratory tests were not noted. His NM resolved completely after the discontinuation of tramadol and the oral administration of clonazepam. Our case report suggests that tramadol can cause NM in patients without seizure history or metabolic disorders, even within its therapeutic dose.

3-methylcrotonyl-coenzyme A carboxylase (3MCC) deficiency is an autosomal recessive disorder in which leucine catabolism is hampered, leading to increased urinary excretion of 3-methylcrotonylglycine. In addition, 3-hydroxyisovalerylcarnitine levels increase in the blood, and the elevated levels form the basis of neonatal screening. 3MCC deficiency symptoms are variable, ranging from neonatal onset with severe neurological abnormality to a normal, asymptomatic phenotype. Although 3MCC deficiency was previously considered to be rare, it has been found to be one of the most common metabolic disorders in newborns after the neonatal screening test using tandem mass spectrometry was introduced. Additionally, asymptomatic 3MCC deficient mothers have been identified due to abnormal results of unaffected baby's neonatal screening test. Some of the 3MCC-deficient mothers show symptoms such as fatigue, myopathy, or metabolic crisis with febrile illnesses. In the current study, we identified an asymptomatic 3MCC deficient mother when she showed abnormal results during a neonatal screening test of a healthy infant.

The release of hormones and the metabolism of human body are controlled by the circadian rhythm related to sleep-wake cycle. Growth hormone, prolactin, thyroid stimulating hormone, cortisol, glucose, and insulin-secretion rates fluctuate according to the sleep-wake cycle. In addition, sleep is related to the appetite regulation and carbohydrate and other energy metabolism. Hypocretin (orexin), an excitatory neuropeptide, regulates waking and diet intake, and the poor sleep increases diet intake. The short sleep duration increases one's body mass index and impairs the function of the endocrine and metabolism, causing increases in the risk of glucose intolerance and diabetes. The poor sleep quality and sleep disorders have similar impact on the metabolic function. In short, the sleep loss and the poor quality of sleep have a detrimental effect on the endocrine and energy metabolism. The improvement of sleep quality by the future research and appropriate clinical treatment would contribute to the decrease of the metabolic diseases such as diabetes.

Disorders resulting from defects in peroxisomal biogenesis include Zellweger syndrome, neonatal adrenoleukodystrophy, and infantile Refsum disease. The three diseases are now considered as a continuum of clinical features. Neonatal adrenoleukodystrophy is intermediate between Zellweger syndrome and infantile Refsum disease in severity, and is characterized by profound hypotonia, intractable seizures and premature death. We report a cases of neonatal adrenoleukodystrophy presenting with neonatal seizure and hypotonia. At the age of 43 months, she had clinical evidence of adrenal insufficiency with skin hyperpigmentation and electrolyte imbalance. She was diagnosed having neonatal adrenoleukodystrophy based on abnormally high levels of plasma very long-chain fatty acids, pipecolic acid and phytanic acid.

BACKGROUND/OBJECTIVES: Mulberry leaves contain quercetin derivatives, which have the effects of reducing obesity and improving lipid and glucose metabolism in mice with obesity. It is not clear whether or not mulberry leaves can directly affect metabolic disorders, in the presence of obesity, because of the interaction between obesity and metabolic disorders. The aim of the current study was to assess the direct action of quercetin derivatives on metabolic disorders in non-obese conditions in short-term high-fat diet fed mice. MATERIALS/METHODS: C57BL/6N mice were fed a high-fat diet, supplemented with either 0% (control), 1%, or 3% mulberry leaf powder (Mul) or 1% catechin powder for five days. Anthropometric parameters and blood biochemistry were determined, and hepatic gene expression associated with lipid and glucose metabolism was analyzed. RESULTS: Body and white fat weights did not differ among the four groups. Plasma triglycerides, total cholesterol, and free fatty acids in the 1%, 3% Mul and catechin groups did not differ significantly from those of the controls, however, plasma glucose and 8-isoprostane levels were significantly reduced. Liver gene expression of gp91phox, a main component of NADPH oxidase, was significantly down-regulated, and PPAR-${\alpha}$, related to ${\beta}$-oxidation, was significantly up-regulated. FAS and GPAT, involved in lipid metabolism, were significantly down-regulated, and Ehhadh was significantly up-regulated. Glucose-metabolism related genes, L-PK and G6Pase, were significantly down-regulated, while GK was significantly up-regulated in the two Mul groups compared to the control group. CONCLUSIONS: Our results suggest that the Mul quercetin derivatives can directly improve lipid and glucose metabolism by reducing oxidative stress and enhancing ${\beta}$-oxidation. The 1% Mul and 1% catechin groups had similar levels of polyphenol compound intake ($0.4{\times}10^{-5}$ vs $0.4{\times}10^{-5}$ mole/5 days) and exhibited similar effects, but neither showed dose-dependent effects on lipid and glucose metabolism or oxidative stress.
