The purpose of this study was to investigate the taste sensitivity in patients with oral mucosal diseases(Oral lichen planus(OLP), Recurrent apthous ulcer(RAU)) using electrogustometer. One hundred and seventy three subjects were included for the study and they were categorized into 2 groups(control 100, patient 73) and patient group was investigated in the Department of Oral Medicine, Pusan National University Hospital from April, 2005 until January, 2007. Control group was investigated in the clinics at Inchen Metroplitan city and Cheongju city from February to August, 2006. The electrical taste thresholds were measured by using an electrogustometer for the 4 different sites(tongue tip, tongue lateral, circumvallate papilla and soft palate) in oral cavity. The results were as follows ; 1. The electrical taste threshold in patient group was significantly decreased than that in the control group(p<0.001). 2. The electrical taste threshold, in terms of the chronicity and lesion multiplicity, was not significantly changed in patient group. 3. The electrical taste threshold was not significantly changed in Dexan only and Dexan+Prs combination treated group. 4. The electrical taste threshold, in terms of treatment progress(no response vs half response vs complete response), was not significantly changed. However subjective index which was determined by NAS(Numerical Analogy Scale) was significantly increased in no response group but significantly decreased in complete response group(p<0.001)

Background: Urinary stones are known predisposing factors for upper urinary tract carcinoma (UUTC) which are commonly detected at advanced stage with poor outcome because of rarity and lack of specific criteria for early detection. Aims and objectives: The main aim was to evaluate the impact of age, gender andstone characteristics on risk of developing UUTC in patients with chronic nephrolithiasis. We also discuss the role of aberrant angiogenesis (AA) and immunohistochemical expression of p53, p16INK4a, CK20 and Ki-67 in diagnosis of pelvicalyceal neoplastic (NL) and pre-neoplastic lesions (PNL) in these patients. Materials and Methods: Retrospective analysis of pelvicalyceal urothelial lesions from 88 nephrectomy specimens were carried out in a tertiary care centre from June 2012 to December 2014. Immunohistochemistry (IHC) was performed on 37 selected cases. Computed image analysis was performed to analyse aberrant angiogenesis. Results: All UUTC (5.7%) and metaplastic lesions were found to be associated with stones. Some 60% were pure squamous cell carcinoma and 40% were transitional cell carcinoma. Odd ratios for developing NL and PNL lesions in presence of renal stone, impacted stones, multiple and large stag horn stones were 9.39 (95% CI 1.15-76.39, p value 0.05), 6.28 (95% CI 1.59-24.85, p value 0.000) and 7.4 (95% CI, 2.29-23.94, p value 0.001) respectively. When patient age was ${\geq}55$, the odds ratio for developing NL was 3.43 (95% CI 1.19-9.88, p value 0.019). IHC analysis showed that mean Ki-67 indices were $3.15{\pm}3.63%$ for non-neoplastic lesions, $10.0{\pm}9.45%$ for PNL and $28.0{\pm}18.4%$ for NL. Sensitivity and specificity of CK20, p53, p16INK4a, AA were 76% and 95.9%; 100% and 27.5%; 100% and 26.5%; 92.3 % and 78.8% respectively. Conclusions: Age ${\geq}55years$, large stag horn stones, multiple stones and impacted stones are found to be associated with increased risk of NL and PNL in UUT. For flat lesions, a panel of markers, Ki 67 index >10 and presence of aberrant angiogenesis were more useful than individual markers.

The explosion of the aging population is changing the social environment of today's older people. Traditionally in Korea, a large percentage(over 90%) of elderly parents have lived with their married first son. But today, the number of elderly who live with their married sons has decreased(65.6%) The number of those who live in a different situation such as with their married daughter, unmarried offspring, with a spouse or alone has increased (34.4%) We can expect that the number of the elderly who have to live in institution will increase. The objective of this investigation was to determine differences in the number of health Complaints of older people according to their living situation with a view to planning more effective health care. The sample consisted of 231 persons over 65 years of age, 60 living in an Old Age Home ana 171 living in their own home in Kwangju. Data were gathered from July 9 to 26, 1983 by nursing students using a Questionnaire which was a modified form of the Cornell Medical Index. The data were categorized according to the subjects, living, sex, educational level, previous occupation, hobbies and sexual activity. The date were analyzed for statistical significant differences using F and X²tests. findings included the following: 1. There was a higher number of health complaints from persons who live in the institution than those living at home, but the difference was not significant. 2. The highest number of health Complaints were from persons who live alone, followed by those living with their daughters, and then by those living in the institution. Persons who live with their sons had the least Complaints. The difference in the number of Complaints accord-ing to with whom they were living was significant. 3. Women had signincantly more Complaints than men. Persons who were not living with their spouses had significantly more complaints than those living with their spouses.4. The higher eductional level the persons had, the less health Complaints they had. The number of Complaints accoraing to educational level was significantly different. 5. The highest number of health complaints were from persons who had involved in Commerce and industry, followed by those in Agriculture. Persons who were civil servant had the least 6. There were more complains from persons who had no hobby than those with hobbies. The complaints. The difference was significant. difference was significant. 7. Persons who said they were sexually inactive had significantly more complaints than those who said they were sexually active. As age increased, sexual activity significantly decreased. Those who lived with their spouse were significantly more sexually active. 8. The highest number of Somatic Complaints were eye fatigue, followed by nocturnal frequency, lumbago, cramps in extremities, vertigo, stiffness in Shoulder, tinnitus, common cold and constipation. The order of Psychic Complaints from higher to lower were anger. sensitivity, anxiety, depression and loneliness. 9. This group of Elderly persons said they valued Health the most, followed by Harmony, Religion, Money and Honor.

To investigate the diagnostic accuracy and applicability of barium enema(BE) and rectal suction biopsy with acetyl cholinesterase(AChE) histochemistry in the diagnosis of neonatal Hirschsprung's disease(HD), we retrospectively reviewed the findings of BE and AChE staining in 96 neonates with suspected HD during a 10-year period from January 1991 to December 2000. Sixty-nine cases of HD(58 males and 11 females) and 27 cases of non-HD are included in this study. In regard to BE, HD was based on definite transitional zone, suspicious HD on reversed rectosigmoid index(RSI <1), and non-HD on normal RSI(RSI>1). The histochemical criterion used for the diagnosis of HD was that of Chow et al(1977), i.e., the presence of many coarse discrete cholinergic nerve fibers in the muscularis mucosae and in the immediately subjacent submucosa regardless of infiltration of cholinergic nerve fibers in the lamina propria. Of 66 neonates with HD who underwent BE, transitional zone was identified in 33 cases(50 %) and reversed RSI in 19 cases(21 %), microcolon in 4 cases and normal finding in 10 cases(15 %) while of 27 neonates with non-HD, there was normal finding in 16 cases and reversed RSI in 9 cases(41 %). Thus diagnostic accuracy based on transitional zone was 64 %. The positive predictive value of reversed RSI for the diagnosis of HD was 68 %. Of 42 neonates with HD who underwent AChE histochemistry, there were 41 AChE-positive reactions and one AChE-negative reaction in a neonate with total colonic aganglionosis, while of 27 cases of non-HD, there were one equivocal AChE-positive reaction and 26 AChE-negative reactions. Thus AChE histochemical study showed a 97 % diagnostic accuracy with a 98 % sensitivity and a 96 % specificity. In conclusion, we believe that BE is valuable as a first diagnostic step since about 80 % of neonates with HD show significant radiologic findings such as a transitional zone or reversed RSI. AChE histochemical study was a more reliable diagnos tic tool showing a 97 % diagnostic accuracy, and is part.

This study aims to analyze the factors that affect quality of life and sensory processing abilities in older adults. Participants were 121 older adults aged over 65. Quality of life was evaluated with Life satisfaction Index for the Elderly and sensory processing abilities were measured with Korean-AASP. Korean Activiy Card Sort was utilized to assess their activity level. Low positive correlations were found between quality of life and activity level in total score(p<.01), IADL(p<.05), leisure(p<.01), and social participation(p<.01). Correlation coefficients between quality of life and sensory processing abilities showed low negative correlations in low registration(p<.01), sensory sensitivity(p<.01), and sensation avoiding(p<.01), however, there were low positive correlations in sensation seeking(p<.05). The importance of sensory processing was highlighted from the findings of statistically significant correlations between quality of life and sensory processing abilities. This indicates that improvement of sensory processing abilities is critical in occupational therapy service for older adults. Furthermore, the findings of close relationship between activity levels and sensory processing abilities need to be reflected in senior welfare policy.

Purpose: The present study was aimed to investigate the change of optical quality in fully cured eyes from central serous chorioretionopathy(CSC) and CSC under treatment, respectively. Methods: A total of 136 eyes(68 subjects) was divided into CMC under treatment and its asymptomatic contralateral eye, fully cured eyes after being diagnosed with CMC and its contralateral eye, and normal eyes. Objective scattering index, cut-off value in modulation transfer function, focusing rate, PSF(Point Spread Function) width at 50%, 10% and the contrast sensitivity were measured and analyzed. Results: CMC under treatment showed statistically significant decrease in all evaluations of optical quality compared with asymptomatic contralateral eyes, fully cured eyes and normal eyes. Although there was no significant difference in optical quality between asymptomatic contralateral eyes of CMC under treatment and fully cured eyes, there was tendence in optical quality decreasing compared with normal eyes. Conclusions: From the study, it was revealed that the optical quality was different according to the treatment phase in CMC. The use of optical quality assessment for the decision of complete cure and the evaluation of prognosis in CMC is also proposed.

Objectives The objective of this study was to investigate the differences in sociodemographic and clinical characteristics, temperaments, and quality of life between panic disorder (PD) patients with and without major depressive disorder (PD+MDD and PD-MDD patients, respectively). Methods We compared 411 PD-MDD and 219 PD+MDD patients. All patients who were drug-free for at least 1 month were assessed at initial outpatient visits before the administration of medication. The following instruments were used for assessment: the NEO Personality Inventory-Neuroticism (NEO-N) ; the Temperament and Character Inventory-Harm Avoidance (TCI-HA) ; the State-Trait Anxiety Inventory (STAI) ; the Intolerance of Uncertainty Scale-Short (IUS); the Anxiety Sensitivity Index-Revised (ASI-R); the Beck Depression Inventory (BDI) ; the Beck Anxiety Inventory (BAI); the Penn State Worry Questionnaire (PSWQ) ; the Generalized Anxiety Disorder for 7 item (GAD-7) ; the Albany Panic and Phobia Questionnaire (APPQ) ; the Panic Disorder Severity Scale (PDSS) ; the Early Trauma Inventory Self Report-Short Form (ETISR-SF) ; the Scale for Suicidal Ideation (SSI) ; the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF) ; the Sheehan Disability Scale (SDS) ; and the Short Form health survey (SF-36). Results Compared to the PD-MDD patients, the PD+MDD patients were younger and more likely to be unmarried. They showed higher rates of unemployment, lower levels of education and income, younger age of onset, more previous suicide attempts, a greater incidence of agoraphobia, and more previous treatments. The PD+MDD patients showed significantly higher scores on the NEO-N, the TCI-HA, the STAI, the IUS, the ASI-R, the BDI, the BAI, the PSWQ, the GAD-7, the APPQ, the PDSS, the ETISR-SF, and the SSI. In addition, the PD+MDD patients showed significantly lower quality of life than did the PD-MDD patients. In contrast with previous studies, we observed no significant differences between the two groups in terms of gender, duration until treatment, and psychiatric comorbidities. Conclusions This study showed that the PD+MDD patients have more early trauma experiences, higher levels of anxiety-related temperaments, more severe panic and depressive symptoms, and lower quality of life than the PD-MDD patients.

Objectives: Recently, the American Diabetes Association (ADA) redefined the criteria of prediabetes, which has lowered the diagnostic level of fasting plasma glucose (FPG) from 110 to 125 mg/dl, down to levels between 100 to 125mg/dl. The purpose of this study was to determine the predictive cutoff level of FPG as a risk for the development of diabetes mellitus in Korean men. Methods: A retrospective cohort study was conducted on 11,423 (64.5%) out of 17,696 males $\leq$30 years of age, and who met the FPG of $\leq$125 mg/dl and hemoglobin A1c of $\leq$ 6.4% criteria, without a history of diabetes, and who were enrolled at the screening center of a certain university hospital between January and December 1999. The subjects were followed from January 1999 to December 2002 (mean follow-up duration; 2.3(${\pm}0.7$) years). They were classified as normal (FPG <100mg/dl), high glucose (FPG $\geq$100mg/dl and <110mg/dl) and impaired fasting glucose (FPG $\geq$110mg/dl and $\leq$125mg/dl) on the basis of their fasting plasma glucose level measured in 1999. We compared the incidence of diabetes between the 3 groups by performing Cox proportional hazards model and used receiver operating characteristic analyses of the FPG level, in order to estimate the optimal cut-off values as predictors of incident diabetes. Results: At the baseline, most of the study subjects were in age in their 30s to 40s (mean age, 41.8(${\pm}7.1$) year). The incidence of diabetes mellitus in this study was 1.19 per 1,000 person-years (95% CI=0.68-1.79), which was much lower than the results of a community-based study that was 5.01 per 1,000 person-years. The relative risks of incident diabetes in the high glucose and impaired fasting glucose groups, compared with the normal glucose group, were 10.3 (95% CI=2.58-41.2) and 95.2 (95% CI= 29.3-309.1), respectively. After adjustment for age, body mass index, and log triglyceride, a FPG greater than 100mg/dl remained significant predictors of incident diabetes. Using the receiver operating characteristic (ROC) curve, the optimal cutoff level of FPG as a predictor of incident diabetes was 97.5 mg/dl, with a sensitivity and a specificity of 81.0% and 86.0%, respectively. Conclusion: These results suggest that lowering the criteria of impaired fasting glucose is needed in Korean male adults. Future studies on community-based populations, including women, will be required to determine the optimal cutoff level of FPG as a predictor of incident diabetes.

Purpose: Whole-body PET using radiopharmaceutical is one of the imaging study methods for physiological changes of body. High specificity of the PET-CT examination is used to detect an early stages of cancer and metastatic cancer by imaging a physiological changes. During the imaging process, PET image has been characterized by a relatively low image quality due to its low sensitivity and the acquisition of random and scatter coincidences as well as patients figure. Therefore, the image quality as the changes of the acquisition times of patient weight was evaluated in this study. Materials and Methods: Thirty patients who presented to our hospital were enrolled. They were divided to normal, overweight, and obese group using BMI index, respectively. The patients with a liver disease and diabetes were excluded. $^{18}F-FDG$ was administered to the patients as 5.2 MBq per kg. After an hour from an injection, image acquisition was obtained as List mode in a part of liver in 1 bed. SNR (signal-to-noise ratio) of each groups acquisition times were confirmed from the calculated radiation counts and random fractions. The statistical significance of three groups was confirmed through one-way ANOVA test. On the basis of the counts of 2 minutes on normal group, the SNR of overweight group and obese group were compared. Results: The SNR were increased with loger aquisition time in 3 groups. In the condition of same acquisition time, the SNR had a statistical significance (P<0.05). The SNR were decreased to the normal, overweight, and obese, respectively. Liver activity had no significance difference on each group and RF had the significance differences (P<0.05). On the basis of the counts of 2 minutes on normal group, there were no statistical significance in a three minute acquisitions of overweight group and two minute acquisitions of obese group (P=0.150). Conclusion: In this study, the administrated amount of radiation dose did not adjust as the change of the patients weight. Increasing the acquisition time when the administration of the same amount of dose was able to get a good result of SNR. When the Based 2 minute on normal group, if overweight and obese case the increased acquisition time of 3 minute was able to obtain a similar SNR. On the basis of the normal group, the acquisition times of overweight and obese group were increased to 3 minutes per bed and the SNR were similar to the normal group.

The aim of this experimental study was to evaluate the anti-tumor effects of Chungsimbohyeltang through investigation about viability of tumor cell by MTT assay, survival period of mice transplanted with L-1210 cells, growth inhibition on the tumor cell, body weight variation in mice transplanted with sarcoma-180 cells and its immunomodulatory effects through the investigation on delayed type hyper-sensitivity, the hemagglutinin and hemolysin titers for humoral immune response, the appearance of rosette forming cells for cell-mediated immune response, the natural killer cell activity, the transformation of lymphocyte, the productivity of Interleukin-2 and phagocytic index K was performed in immune-depressed ICR mice induced by methotrexate treatments. The results were as follows ; 1. $IC_{50}$ of Chungsimbohyeltang treated group was 5.85mg/ml in SNU-C4 cell, 1.38mg/ml in SNU-396 cell, 0.21mg/ml in SNU-1 cell, so it had low anti-tumor activity. 2. The both groups of Chungsimbohyeltang extract 10mg/kg and Chungsimbohyeltang extract 20mg/kg had no toxicity and the group of Chungsimbohyeltang 20mg/kg which was shown 120% in ILS had the effect of life prolongation in mice transplanted with L-1210 cells. 3. In the growth inhibition on the tumor cells, only the group of Chungsimbohyeltang extract 20mg/kg was noted and in the weight variation in mice transplanted with sarcoma-180 cells, both groups of Chungsimbohyeltang extract had a significant effect. 4. In the delayed type hypersensitivity and appearance of rosette forming cells, both groups of Chungsimbohyeltang extract didn't have any significant effect. 5. The hemagglutinin titers was slightly increased with no significance, and the hemolysin titers was significantly increased in the only group of Chungsimbohyeltang extract 20mg/kg. 6. The natural killer cell activity of the Chungsimbohyeltang extract groups was significantly increased in the ratio of 100:1 of effector and target cells, but it was not significantly increased in the ratio of 50:1, 10:1. 7. The transformation of lymphocyte and the productivity of Interleukin-2 were increased significantly and in dose-dependent manner in both group of Chungsimbohyeltang extract. 8. The phagocytic effect of macropage was significantly increased in both groups of Chungsimbohyeltang extract. Considering the results above, we could conclude that Chungsimbohyeltang have an indirect anti-tumor effect through the modulation of immunme response, although it had not toxicity on the tumor cell it self.
