Renal osteodystrophy(RO) is characterized by skeletal changes in patients with renal disease and developed as a result of alterations in the metabolism of calcium, phosphate and secondary hyperparathyroidism. Bony changes in the craniofacial region include decreased bone density, radiolucent lesions(brown tumors), depletion of cortical bone and loss of lamina dura, but such changes rarely occur in the temporomandibular joint(TMJ). We report an uncommon case of bony changes and pain of both TMJs in a patient with RO. A 41-year-old man with RO came to our clinic due to TMJ pain and sounds. Occlusal change was also reported. Radiographs revealed degenerative changes of the both condyles. The patient had medical history of renal cancer therapy and hemodialysis. The patient was diagnosed with TMJ arthritis of RO and referred for systemic management through medication of calcium and vitamin D and parathyroidectomy. At 15-month follow-up, most of TMD symptoms disappeared and second radiographs revealed that bone density and cortical thickness of the mandible increased and the skeletal outline of the both condyles became relatively clear. As bony changes may begin in the early stage of the renal disease, dentists should be alert to detect the sign of the disease. In addition, it is important to differentiate TMJ arthritis of systemic cause because the treatment protocol is quite different.

Lesch-Nyhan syndrome is a disease caused by metabolic disorder of purine. General muscle stiffness and hyposomia are shown from infancy and symptoms can include involuntary or irregular movements of arms and legs, mental retardation, and compulsive self-mutilating behaviors. Self-mutilating behaviors begin at approximately the first year or sometimes at late teens. The patients bite their lips, especially lower lip, tongue, buccal mucosa, hands and fingers. Tongue and lips can be injured or mutilated in severe cases. As the patient gets older, self-mutilating behaviors become more serious and extensive and secondary infection of injured areas is possible. Periodic soft tissue damage due to self-mutilating may evolve to cancer. Medical treatment, appliance treatment, extraction of tooth and surgical operation was attempted to control self-mutilaing behaviors. We hereby report the case of child Lesch-Nyhan syndrome patient who has self-inflicted labial damage as chief complaint. When patient was treated with conservate therapy, such as removable or fixed appliance, the frequency of labial damage could be subdued and yielded favorable results.

Objectives: This study describes the results of a mass screening and secondary questionnaire conducted among sampled residents around Camp Carroll. Methods: The subjects were sampled based on Waegwan groundwater ingestion history via a primary health questionnaire survey. However, the study population included voluntary participants and there were no grounds for disqualification. Among the 1,033 residents, excluding people living outside Waegwan, 844 subjects age 30 and over were analyzed. History of physician-diagnosed disease (including detailed history of cancer), eating habits, drinking and smoking histories were queried through questionnaires. Health screening consisted of a blood pressure check and blood test (complete blood cell, liver enzyme, lipid, blood sugar test, etc.). Results: The proportion of abnormal gamma-glutamyltransferase levels was higher in the groundwater ingesting female group than the non-ingesting female group. The odds ratios of the ingested '1 to 9 years' and '10 years and over' groups were 3.09 and 0.87, respectively. Proportions of hypertension in males, abnormal serum triglyceride levels in all and in females, and abnormal serum high density lipoprotein cholesterol levels in males were higher in the '10 to 29-year' resident group than in the '1 to 9 year' group. However, there were no significant trends according to length of residence. Conclusions: Physician-diagnosed prevalence and laboratory test results are not different by histories of Waegwan groundwater ingestion and by length of residence. Even if there are partially significant differences, they do not tend to follow increases of exposure amount and trends.

Myelodysplastic syndrome (MDS) is a typical myeloid malignancy characterized by cell dysplasia in bone marrow. Currently, there is no therapeutic treatment for MDS. The only available therapies either relieve symptoms or prevent the development of acute myeloid leukemia (AML). This study aimed to report the effects of traditional Korean medicine (TKM) on MDS by presenting two case reports. The patient in Case 1 was diagnosed with primary MDS and regularly received acupuncture treatments and herbal medicine. In Case 2, a patient with ovarian cancer was diagnosed with secondary MDS, which resulted from an adverse reaction to chemotherapy. This patient took herbal medicine for four years and was hospitalized three times. In order to have their condition evaluated, both patients underwent regular blood tests. The patient in Case 1, who showed blood transfusion dependency, received only two blood transfusions after TKM treatment, and the person’s health condition was stable as of January 2016 without any signs of AML development. The patient in Case 2 also has stable health condition. TKM treatment effectively treated their MDS symptoms and improved their general health conditions without any adverse effects. It also prevented the rapid development of AML and maximized the effects of conservative therapy.
Abeliophyllum distichum Nakai is deciduous shrubs of flowering plant in Oleaceae. It is important plant resources and consists of one species in the world. Also the endemic plant of A. distichum has been protected and designed endangered plant in Korea. For this reason, study on the immature seeds of A. distichum (ADS) hasn't progressed. In the present study, we evaluated the antioxidant activity and inhibitory effects on proteins and mRNA levels were related in the whitening effect in B16F10 cells. ADS was effective for reaction oxygen species (ROS). ROS causes various diseases such as aging, inflammation, cancer, and etc. Antioxidant properties were evaluated DPPH, ABTS radical scavenging activity and Reducing power. Plants were known that contained phenolic compounds were related in antioxidant activity. Phenolic compounds were phytochemicals commonly named natural polyphenols. These are secondary metabolites of plants involved in the defense against different types of stresses. In results, ADS suppressed the expression and transcription of Tyrosinase, TRP-1, TRP-2, and Microphthalmia-associated transcription factor (MITF). Tyrosinase, tyrosinase-related protein 1 (TRP-1), tyrosinase-related protein 1 (TRP-2) are known to play an important role in melanin biosynthesis. MITF regulated the expression and transcription of Tyrosinase, TRP-1, and TRP-2. In conclusion, ADS was effective in both antioxidant activities and whitening effects. Also, they were associated with the content of phenolic compounds. We suggested that ADS can be use antioxidants and skin-whitening functional cosmetics material derived from natural plant resources.
An efficient and reproducible procedure for the large scale propagation of Hovenia dulcis Thunb. is described. Shoot primodia emerging from the leaf surface was induced from MS medium supplemented with NAA. Stem cuttings were suitable explants for multiple shoot proliferation. They produced axillary shoots which branched repeatedly, yielding an average of 7 shoots per explants after 4 weeks in culture, when cultured on a woody plant medium (WPM) containing 0.1mg/l BA and 0.1mg/l NAA. Stem, leaf and root segments from axenic seedlings were used as explant source to induce somatic embryogenesis. A high frequency of somatic embryos were induced directly from leaf in MS medium with NAA, 2,4-D and in medium containing NAA, 2,4-D with BA. Somatic embryos were germinated in MS medium supplemented with 1mg/ l $GA_3$. Somatic embryos proliferated secondary somatic embryos rapidly after transfer to MS medium supplemented with 1mg/ l kinetin, 1mg/ l $GA_3$ and 2% dextrose.
This study firstly examined the socioeconomic and health factors associated with infiltration of private health insurance. Secondly, we compared health behavior, outpatient and inpatient use of private health insured with uninsured. The method of this study is that secondary analysis of the 2008 Korea National Health and Nutrition Survey was conducted for 7178 respondents aged 19 over. We use the logistic regression and t-test for data analysis. The first dependent variable was dichotomy which is divided to private health insured or uninsured and the second dependent variable was the presence and frequency of outpatient and inpatient use. The descriptive variables was gender, age, marital status, income, education, occupation, type of national health insurance, residential area, self confidence of health, prevalence rate of common disease, activity limitation, drinking and smoking status. The result of the major findings are as follows. First, 59 under aged person, married person, people in the higher brackets of income, national employee insured were more likely to infiltrate private health insurance. The poor self confidence of health, activity limitation, person with hypertension or allergic rhinitis and smoker were negatively related in infiltrating private health insurance. Second, private health insured did more preventive behavior such as self-paid health examination, cancer screening, regular exercise than uninsured. Third, private health insured was positively related with the presence of outpatient use and frequency of inpatient use

Purpose: Numerous techniques have been introduced to reconstruct the perineal area in order to preserve function of both the recipient and the donor site while satisfying aesthetic results. There are several advantages of using the pudendal aretery perforator based flap in that it provides thin coverage of defect area and a relatively excellent circulation through perforators. The perineal region can be divided into two areas : the urogenital triangle and the anal triangle. Since each area differs in structure and function so does its reconstructive plan. The authors of this article report clinical results obtained from pudendal artery perforator based reconstructed cases according to each differrent triangles. Methods: A total of 15 patients who underwent perineal reconstruction were enrolled in our study between the year 2002 and 2006. There were 4 cases of vaginal cancer, 4 cases of extramammary Paget's disease, 1 case of rectovaginal fistula in females and 2 cases of Paget's disease and 4 cases of Fournier's gangrene in male cases. The follow up period was on average 6 month. In female, superfical pudendal artery perforator based local flap were used to reconstruct the urogenital triangle defects, while internal pudendal artery perfoator based local flaps were used to reconstruct the anal traingle defects. In males the gracilis myocutaneous flap and internal pudendal artery perforator based local flaps were used in reconstruction of the scrotum and perineal defect. Result: In females, there was 1 case of partial flap necorsis that employed the superficial pudendal artery perforator but secondary repair through the internal pudendal artery perforator based local flap was done. In addition, there were 4 wound dehiscence cases in females and 2 cases in males. Conclusion: We believe that a better aesthetic and functional outcome can be achieved in perineal reconstruction if discrete surgical planning is carried out systematically categorizing the choice of flap employed acccording to distinct anatomical regions : the urogenital and the anal triangle.
Recently, as consumers' interest and importance in health care have significantly increased, they prefer natural and organic foods that do not use chemical pesticides. Since sprout vegetables effectively promote health and prevent diseases such as cancer and cardiovascular disease, the consumption of sprout vegetables, a highly functional and safe food, has been increased significantly. This study aimed to investigate the effect of light on the growth and bioactive compounds of seven different sprout vegetables. After sowing the seeds of various sprout vegetables (kale, Chinese kale, broccoli, red cabbage, alfalfa, red radish, and radish), the sprouts were cultivated under light conditions (20℃, RGB 6:1:3, 130 μmol·m-2·s-1, 12 hours photoperiod) and dark condition for 7 days. Sprouts samples were taken at 1-day intervals from 4 to 7 days after treatment. The fresh weight, dry weight, plant height, total phenol content, and antioxidant capacity were measured. Brassica species (kale, Chinese kale, broccoli, red cabbage) and Medicago species (alfalfa) had significantly higher fresh weight values under dark conditions, while the content of bioactive compounds was increased considerably under light conditions. In contrast, the fresh weight of Raphanus genus (red radish, radish) significantly increased under the light condition, but the antioxidant phenolic compounds were significantly higher under the dark state. A negative correlation was observed between the growth and secondary metabolites in various sprout vegetables. This study confirmed the effect of light and dark conditions on different sprout vegetables' growth and nutritional value and emphasizes the importance of harvest time in producing high-quality sprout vegetables.
Ettringite $(Ca_6[Al(OH)_6]_2(SO_4)_3{\cdot}26H_2O)$ is a sulfate mineral that shows a complicate property in concrete. It is often called as "a cancer of concrete" because secondary ettringite formation in hardened concrete often cause expansion and cracking of concrete due to its expansive crystal structure. In the present study, we tested the possibility for crystal growth inhibition of secondary ettringite by crystallization inhibitors that are commercially used for scaling inhibitors in Korea. For the test, we developed a method of ettringite solution synthesis. Three types of crystallization inhibitors were selected and examined the effects On ettringite growth inhibition. The experimental results of ettringite solution synthesis indicated that ettringite was successfully synthesized under condition that the mass balance between calcium hydroxide saturated solution and aluminum sulfate solution was attained. Monosulfate and semisulfate were synthesized when the ratio of $Ca^{2+}$ ions to ${SO_4}^{2+}$ ions was increased. The induction time of ettringite crystallization was less than 2 min. and crystallization was almost completed within an hour. The experimental results of ettringite crystallization inhibition showed that organic PBCT (2-Phosphonobutane-1,2,4-Tricarboxylic Acid) and inorganic SHMP (Sodium Hexametaphosphate) were relatively less effective on ettringite crystallization inhibition under experimental conditions. However, organic HEDP (1-Hydoxyethylidene-1,1-Diphosphonic Acid) effectively prevented ettringite growth with producing amorphous gel phase materials up to inhibitor concentration 0.1 vol.% of aluminum sulfate solution.
