PURPOSE: To evaluate whether factors related to lipid and glucose metabolism have a potential role in the progression of prostate cancer, we measured the mRNA levels of the peroxisome proliferator-activated receptor (PPAR), fatty acid elongase (ELOVL), and two glycolytic enzymes in prostate cancer (CaP) tissues. MATERIALS AND METHODS: Prostate tissues, obtained from radical prostatectomy (n=10) and transurethral resection of prostate (n=18), were quickly frozen in liquid nitrogen for RNA measurements. Transcript signals of PPAR alpha, PPAR gamma, ELOVL2, ELOVL5, phosphoglycerate kinase 1 (PgK1) and phosphoglycerate mutase 2 (PgM2) were measured using a reverse-transcription polymerase chain reaction. RESULTS: The transcript signals of PPAR alpha and PPAR gamma were down-regulated in CaP tissues. In addition, the mRNA level of PgM2 in CaP tissues was lower than that in benign prostatic hyperplasia (BPH) tissues. However, the messages for ELOVL2, ELOVL5, and PgK1 were not significantly changed. CONCLUSIONS: These results suggest that lowering of the PPARalpha, PPARgamma and PgM2 messages may be involved in aberrant and uncontrolled prostate cell growth and differentiation.

Recently, mini-implant is popular in the orthodontic treatment due to its simplicity and convenient surgical procedure. The objective of this study is to provide the anatomical guideline for mini-implant placement by analysing the cortical bone thickness in Korean. Hemi-sections of sixteen maxillae and twenty-two mandibles with normal teeth were used. Interdental areas between the 1st premolar and the 2nd premolar (Group 1), the 2nd premolar and the 1st molar (Gruop 2), and the 1st molar and the 2nd molar (Group 3) were sectioned and then scanned. After setting the axis of teeth, the cortical bone thickness was measured at the distance of 2 mm, 4mm, 6 mm, and 8 mm from alveolar crest. The mean thickness of cortical bone in the maxilla according to distance from alveolar crest was 1.30 +/- 0.63 mm (2 mm), 1.49 +/- 0.62 mm (4mm), 1.72 +/- 0.64 mm (6mm), and 1.90 +/- 0.90 mm (8 mm) at the buccal side and 1.33 +/- 0.47 mm, 1.31 +/- 0.45 mm, 1.37 +/- 0.55 mm, and 1.39 +/- 0.58 mm at the palatal side. In the mandible, that was 3.14 +/- 1.71 mm, 4.31 +/- 2.22 mm, 4.23 +/- 1.94 mm, and 4.30 +/- 1.57 mm at the buccal side and 1.98 +/- 0.88 mm, 2.79 +/- 1.01 mm, 3.35 +/- 1.27 mm, and 3.93 +/- 1.38 mm at the lingual side. The buccal cortical bone thickness in the maxilla was decreased from Group 1 to Group 3, while the thickness of palatal side was no change. In the mandible, it did not show a tendency at the buccal side and it was decreased from Group 1 to Group 3 without significant difference at the lingual side. Therefore, the buccal side of the Group 1 and Group 2 in both the maxilla and mandible seems to be the most appropriate site for a mini-implant placement with taking the stability and retention.

OBJECTIVES: The aim of this study was to develop the Korean version of the Warwick-Edinburgh Mental Well-being Scale (K-WEMWBS) and to examine its factorial structure, reliability, and convergent/discriminant validity. METHODS: In this study, the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), a self-rating measure for assessment of mental well-being, was translated into Korean. It was completed by 222 respondents, including 117 healthy subjects and 105 psychiatric patients from both inpatient and outpatient clinics at Soonchunhyang University Hospitals in Bucheon, Cheonan, and Seoul. RESULTS: The K-WEMWBS showed good content validity. Confirmatory factor analysis supported a single factor structure. The Cronbach's alpha value for the K-WEMWBS was 0.944, which demonstrated good internal consistency. Test-retest reliability at 2-8 weeks was high (0.789). The K-WEMWBS showed high correlations with mental health, positive affect, and quality of life scales. Moderate negative correlation was observed between the K-WEMWBS and the negative affect scale. Discriminant validity was partially identified. Statistically significant differences in scores were observed between the psychiatric patient group and the control group. CONCLUSION: The results of this study indicate that the K-WEMWBS is a reliable and valid instrument for assessment of mental well-being, particularly the positive aspects of mental health.

BACKGROUND/AIMS:
To investigate the drug survival rate of tacrolimus (TAC) and analyze the potential predictors of this rate in patients with rheumatoid arthritis (RA) in routine care.
METHODS:
2018-01-16: In this retrospective longitudinal study, we enrolled 102 RA patients treated with TAC from April 2009 to January 2014 at a tertiary center in South Korea. The causes of TAC discontinuation were classified as lack of efficacy (LOE), adverse events (AEs), and others. The drug survival rate was estimated using the Kaplan-Meier method and the predictors of this rate were identified by Cox-regression analyses.
RESULTS:
TAC was discontinued in 27 of 102 RA patients (26.5%). The overall 1-, 2-, 3-, and 4-year TAC continuation rates were 81.8%, 78.4%, 74.2%, and 69.1%, respectively and the median follow-up period from the start of TAC was 32.5 months. The number of TAC discontinuations due to LOE, AEs, and others were 15 (55.6%), 11 (40.7 %), and 1 (3.7%), respectively. The baseline high disease activity was a significant risk factor for TAC discontinuation after adjusting for confounding factors (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.16 to 5.35; p = 0.019). In addition, underlying interstitial lung disease was significantly associated with TAC withdrawal due to AEs (HR, 3.49; 95% CI, 1.06 to 11.46; p = 0.039).
CONCLUSIONS
In our study, TAC showed a good overall survival rate in patients with RA in real clinical practice. This suggests that the long-term TAC therapy has a favorable efficacy and safety profile for treating RA.

Purpose:
To analyze the degree of psychological distress experienced pre- and postoperatively in patients who underwent radical prostatectomy after being diagnosed with prostate cancer.
Materials and Methods:
Patients diagnosed with prostate cancer who underwent radical prostatectomy without history of psychiatric disorders were included in this study. The degree of psychological distress was evaluated using hospital anxiety and depression scale (HADS) and distress thermometer (DT) questionnaires preoperatively and at 1, 3, 6, and 12 months postoperatively.
Results:
Distress was high preoperatively and decreased over the entire period. In addition, HADS-anxiety and HADS-depression scores showed an improved severity, shifting from an abnormal state to a borderline state in some patients. However, the DT score, including emotional problems, spiritual concerns, physical problems, family problems, and practical problems, was slightly higher at 1 month postoperatively compared to preoperatively. Furthermore, even at 12 months postoperatively, about one fifth of patients surveyed had a DT score of 4 or higher, requiring psychiatric intervention.
Conclusions
Before and after radical prostatectomy, a significant number of patients complained of distress such as anxiety, depression, and insomnia, and they needed help from a specialist because of psychological distress even 12 months postoperatively.Therefore, a close evaluation of the patient’s psychological distress and supportive treatment are needed during the entire pre- and postoperative period.

We already reported that genetically engineered resveratrol-enriched rice (RR) showed to down-regulate skin melanogenesis. To be developed to increase the bioactivity of RR using calli from plants, RR was adopted for mass production using plant tissue culture technologies. In addition, high-pressure homogenization (HPH) was used to increase the biocompatibility and penetration of the calli from RR into the skin. We aimed to develop anti-melanogenic agents incorporating calli of RR (cRR) and nanoparticles by high-pressure homogenization, examining the synergistic effects on the inhibition of UVB-induced hyperpigmentation. Depigmentation was observed following topical application of micro-cRR, nano-calli of normal rice (cNR), and nano-cRR to ultraviolet B (UVB)-stimulated hyperpigmented guinea pig dorsal skin. Colorimetric analysis, tyrosinase immunostaining, and Fontana-Masson staining for UVB-promoted melanin were performed. Nano-cRR inhibited changes in the melanin color index caused by UVB-promoted hyperpigmentation, and demonstrated stronger anti-melanogenic potential than micro-cRR. In epidermal skin, nano-cRR repressed UVB-promoted melanin granules, thereby suppressing hyperpigmentation. The UVB-enhanced, highly expressed tyrosinase in the basal layer of the epidermis was inhibited by nano-cRR more prominently than by micro-cRR and nano-cNR. The anti-melanogenic potency of nano-cRR also depended on pH and particle size. Nano-cRR shows promising potential to regulate skin pigmentation following UVB exposure.

PURPOSE: Paraquat (1,1-dimethyl-4,4'-bipyridylium chloride) is widely a used non- selective herbicide. In spite of efforts to improve the outcome in patients poisoned with paraquat, the mortality rates still remains high. The purpose of this study is to identify initial stat laboratory parameters which can affect the survival rate of these patients. METHODS: A retrospective analysis by chart review was done on 67 patients who had ingested paraquat and who had presented to the Emergency Medical Center of Chonnam University Hospital from June 1997 to July 2001. RESULTS: The results were as follows: 1) Survivors were significantly younger than the nonsurvivors (38 years vs 44 years, p=0.03). The volume of paraquat ingested by survivors was significantly smaller than that ingested by the deceased (1 mouthful vs 3 mouthfuls, p<0.001). 2) The WBC count and the levels of serum AST, BUN and serum creatinine in the deceased were significantly higher than those in the survivors. The levels of serum potassium and bicarbonate, arterial pH, and base excess in survivors were significantly higher than those in the deceased. 3) A multivariate analysis revealed that serum creatinine, serum potassium, and arterial base excess were associated with the fatality rate. CONCLUSION: Initial stat laboratory parameters including arterial blood gas analysis, renal function test, and serum electrolytes could be used to predict the outcome of patients poisoned with paraquat. However, the development of readily applicable and reliable indices predicting outcome is desired for the future.

PURPOSE: The purpose of this research was to evaluate the factors predicting recurrence and the characteristics of patients who recurred after the treatment of spontaneous paroxysmal supraventricular tachycardia (PSVT) with adenosine. METHODS: From January 1999 to December 2001, 62 patients with PSVT were enrolled in this study. The conversion group included patients who had had a therapeutic response, which was defined as the occurrence of a change in the sinus rhythm after adenosine administration. The recurred group consisted of all patients who had not had a therapeutic response. Clinical features, the results of treatment, ECG findings, and the hemodynamic statuses were analyzed. RESULTS: The treatments were vagal maneuver (5 pts, 7.5 %), adenosine 6 mg (37 pts, 55.2 %), adenosine 12 mg (14 pts, 20.9 %), verapamil 5 mg (9 pts, 13.4 %), and cardioversion (2 pts, 3.0 %). Twenty-five of the 62 patients failed to have a therapeutic response, yielding a recurrence rate of 40.3 %. Atrioventricular reentrant tachycardia (AVRT) was more prevalent in the recurred group. The most common symptom at presentation was chest pain. The recurred group had increased heart rate, and increased blood pressure. When patients were monitered after adenosine, unifocal premature ventricular complex was the most common rhythm encountered in the conversion group, but atrial fibrillation, and multifocal premature ventricular complex was the most common rhythm encountered. CONCLUSION: Age, heart rate, difference in systolic blood pressure from presentation to discharge, previous history of heart disease, and rhythms encountered after adenosine administration were factors predicting recurrence.

OBJECTIVES: This study investigated on the severity of dry mouth in the hansen people and the association between dry mouth(low, moderate and high) with pre and post wearing denture satisfaction. METHODS: Data were obtained from a cross-sectional survey of 104 hansen people(mean age=69.3). Data were collected by means of a personal interview from April 30 through to Jane 20, 2014. Pre and post wearing denture satisfaction was measured by the 24-items and dry mouth was measured by the 4-items. The data was analysed with t-test, One-way ANOVA, and Logistic regression using the SPSS program. RESULTS: Regarding perception of dry mouth, the subjects achieved a mean of 6.13 out of a maximum 12 points. Scores were categorised as high(8~12), medium(5~7) or low(1~4) and the proportion were 24.5%(9.56), 42.2%(5.81) and 33.3%(4.00) respectively. Those who were older and had fewer natural teeth felt that their perception of dry mouth was more severe. A logistic regression analysis showed that the subjects perception of dry mouth had a significant impact on their gender (OR=2.73), comfort (OR=0.21), aesthetic appreciation (OR=7.56) satisfaction. CONCLUSIONS: Based on the findings, the perception of dry mouth has a significant and negative impact on denture satisfaction. These results suggest that oral health promotion should be considered various factors related dry mouth in the elderly with removable denture.
