The external treatment of internal diseases was first recorded in Hwangjenaegyeong(黃帝內經), and two hundred and fifty odd cases were found in the Bonchogangmok(本草綱目) and Oechisusebang(外治壽世方). Bonchogangmok(本草綱目) is a technical book devoted to explaining materia media as well as the external treatment of internal diseases. Oechisusebang(外治壽世方) is also a technical book, which make 36 references to the disease patterns of internal medicine. The medicinals employed as external treatment of internal diseases are grouped into 300 classes. These medicinals do not set limits to trees and plants but also uses birds and beasts, reptiles, grains, feces and urine, soil, stone etc., applied to various disease patterns. This study researched the medical texts in order to treat the disease patterns of internal medicine.

A new algorithm for estimating bladder volume for portable bladder volume measurement system is proposed. Given the actual image of a bladder, edges between bladder wall and urine are extracted first. Axes are calculated from these data and actual cross section shape is obtained by filtering. Since ordinary shape of a bladder is irregular, two cross-sections(transverse and longitudinal) are considered. With the area of a longitudinal cross-section projected along the axes of transverse cross-section, or vice versa, two estimated volume are obtained. Averaging these two value yields the volume of the bladder. Applied to actual experiments, the proposed algorithm showed explicitly good results in comparison with the conventional techniques.

A case of nonsecretory multiple myeloma in a 66 year-old-woman is reported. At first, she complained severe neck pain and radiologic finding showed C2 pathologic fracture. She complained severe low back pain 4 month later and L1 compression fracture was found. The lumbar MRI showed a 1.4cm-sized round enhancing lesion in the body of T12. Bone marrow aspiration biopsy at L1 spine showed a few polymorphous and small nests of mononuclear cell. L1 lamina bone biopsy showed many abnormal plasma cells. Pathologic diagnosis was multiple myeloma. However, plasma electrophoresis and protein immunoelectrophoresis of serum and urine of patient were normal. So, it is a nonecretory multiple myeloma case and the incidence of nonsecretory multiple myeloma is known to about 1% of all multiple myeloma.

Oryeong-san which was first recorded in Shanghanrun describing the treatments of acute febrile disease is one of the frequently used oriental medicines. Oryeong-san has been prescribed for the treatment of symptoms accompanied by edema. The purpose of this study was to examine the diuretic effects of Oryeong-san by different routes of administration. Oryeong-san (100 mg/kg body weight) was administrated by three different routes in Sprague-Dawley rats: intravenous infusion, intraperitoneal injection and oral intake. Oral intake of Oryeong-san significantly increased urinary volume and excretion of $Na^+$, $Cl^-$, and $K^+$ compared to vehicle-treated control group. The effects were concentration-dependent. Intravenously administrated Oryeong-san increased urinary volume and electrolyte excretion but without significance in hydrated (0.02 ml/min/rat for 90 min) anesthetized rats. Similarly, intraperitoneally injected Oryeong-san had no effects on water and urine electrolyte excretion compared with saline control group. These findings suggest that Oryeong-san has different effects on water and electrolyte balance by routes of administration.

Methylmalonic acidemia (MMA) is an autosomal recessive metabolic disorder characterized by an abnormal accumulation of methylmalonyl-CoA and methylmalonate in body fluids without hyperhomocysteinemia. Cardiac disease is a rarely known lethal complication of MMA, herein, we report a Korean neonate diagnosed with MMA on the basis of biochemical and genetic findings, who developed cardiomyopathy, resulting in sudden death. The patient presented vomiting and lethargy at 3 days of age. Initially, the patient had an increased plasma propionylcarnitine/acetylcarnitine concentration ratio of 0.49 in a tandem mass spectrometry analysis and an elevated ammonia level of $537{\mu}mol/L$. Urine organic acid analysis showed increased excretion of methylmalonate. Subsequent sequence analysis of the methylmalonyl-CoA mutase (MUT) gene revealed compound heterozygous mutations c.323G>A (p.Arg108His) in exon 1 and c.1033_1034del (p. Leu345Serfs*15) in exon 4, the latter being a novel mutation. In summary, this is the first case of MMA and cardiomyopathy in Korea that was confirmed by genetic analysis to involve a novel MUT mutation.

Background: The new type of diabetes treatment, SGLT2 inhibitors, has been approved for monotherapy and combination therapy, but medical insurance is only allowed in combination therapy with metformin, which is the first choice for type 2 diabetes treatment. Methods: The SGLT2 inhibitors prescribed in Korea are dapagliflozin, empagliflozin and ipragliflozin. A review was conducted using Pubmed to evaluate efficacy and safety for these medications with metformin combination therapy. 10 studies were selected by searching for keywords and related references and were reviewed in full. The mechanism of action, pharmacokinetics, and the economics of treatment with SGLT2 inhibitors were examined. Results: SGLT2 inhibitors had moderate glycemic control when added to the treatment of patients with type 2 diabetes who were not being regulated by metformin monotherapy. They also showed positive effects such as weight loss, as well as the lowering of blood pressure. Hypotension and serious side effects were relatively low. However, the risk of genital infection was increased. Conclusion: The SGLT2 inhibitors are a new class of drugs that promote glucose excretion in the urine. They are a good choice for combination therapy with metformin for the treatment of type 2 diabetes, with weight loss and very low risk of serious side effects.

Background: Korea has experienced rapid economic development in a very short period of time. A mixture of traditional and modern risk factors coexists and the rapid change in non-genetic factors interacts with genetic constituents. With consideration of these unique aspects of Korean society, a large-scale genomic cohort study-the Health Examinees (HEXA) Study-has been conducted to investigate epidemiologic characteristics, genomic features, and gene-environment interactions of major chronic diseases including cancer in the Korean population. Materials and Methods: Following a standardized study protocol, the subjects were prospectively recruited from 38 health examination centers and training hospitals throughout the country. An interview-based questionnaire survey was conducted to collect information on socio-demographic characteristics, medical history, medication usage, family history, lifestyle factors, diet, physical activity, and reproductive factors for women. Various biological specimens (i.e., plasma, serum, buffy coat, blood cells, genomic DNA, and urine) were collected for biorepository according to the standardized protocol. Skilled medical staff also performed physical examinations. Results: Between 2004 and 2013, a total of 167,169 subjects aged 40-69 years were recruited for the HEXA study. Participants are being followed up utilizing active and passive methods. The first wave of active follow-up began in 2012 and it will be continued until 2015. The principal purpose of passive follow-up is based on data linkages with the National Death Certificate, the National Cancer Registry, and the National Health Insurance Claim data. Conclusions: The HEXA study will render an opportunity to investigate biomarkers of early health index and the chronological changes associated with chronic diseases.

Hunter syndrome(Mucopolysaccharidosis type II, MPS type II) is an X-linked disorder of glycosaminoglycans (GAGs) metabolism caused by an iduronate-2-sulfatase (IDS2) deficiency. A 24-month-old boy visited the department of pediatrics with the chief compliant of chronic purulent rhinorrhea beginning at age one. He had a history of repeated acute otitis media and chronic rhinitis. On physical examination he had a coarse face, enlarged tongue, distended abdomen, joint stiffness, and Mongolian spots at his first visit. The urine GAGs level was elevated at 66.10 mg/mmolCr (reference range, <11.1) and iduronate-2-sulfatase activity in leukocyte was decreased at 0.21 nmol/mg protein/hr (reference range, 18.7-57). Finally with an IDS gene mutational analysis, recombinant known mutation between intron 7 and distal of exon 3 in IDS2 was detected. Recombinant iduronate-2-sulfatase therapy was started without any infusion related reactions. The author highlights the importance of suspecting Hunter syndrome when pediatric patients visit with chronic purulent rhinorrhea which is a common cause of hospital visits for infants and children.

BACKGROUND: In this study, we have attempted to identify a urinary biomarker to assess chlorpyrifos exposure in farmers. The major metabolite and the excretion pathway of chlorpyrifos is 3,5,6-trichloro-2-pyridinol (TCP) in urine. Herein, we describe an adequate synthetic method for TCP hapten for measuring urinary TCP of farmers. METHODS AND RESULTS: First, TCP was prepared by spacer attachment through hydrolysis of thiophosphate ester from chlorpyrifos. After reaction with benzyl bromide, the TCP was transformed into 2,3,5-trichloro-6-benzyloxypyridine. Next, the chlorine in the 2 ^nd position of the pyridyl ring was substituted into 3-mercaptopropanoic acid spacer arm. Finally, the phenyl group attached to the 6 ^th position in pyridyl ring was removed for producing the targeted product, 3-(3,5-Dichloro-6-hydroxy-2-pyridyl) thiopropanoic acid. CONCLUSION: Henceforth, this TCP hapten would be used in developing immunoassay studies for the detection and quantitation of urinary TCP of farmers.
