OBJECTIVE: The presence of the various cytokines in human peritoneal fluid has been evaluated incompletely. Changes in cytokine lefels may be related to activation of peritoneal macrophage and T-lymphocyte, development of endometriosis, and infertility. This study assesses peritoneal fluid levels of interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-alpha) in infertile women with endometriosis and normal women without endometriosis. Design : Prospective and case-control study in university hospital. MATERIALS AND METHODS: Cytokine levels in peritoneal fluid obtained during laparotomy or laparoscopy from 21 patients in infertile patients in infertile patients with endometriosis and 24 controls undergoing laparotomy or laparoscopy with no evidence of pelvic endometriosis were determined by enzymelinked immunosorbent assay. RESULTS: The mean levels of interleukin-6 in infertile patients with endometriosis and controls were 72.7+/-23.7 pg/ml and 18.5+/-9.7 pg/ml respectively (p=0.02). Similarly, the mean levels of interleukin-8 in infertile patients with endometriosis was significantly higher than that of controls (445.0+/-89.6, vs 45.1+/-48.4, p=0.04). The mean concentration of interleukin-10 in infertile patients with endometriosis was significantly lower than that of controls (1.09+/-0.04 vs 2.19+/-0.03, p=0.03). The level of tumor necrosis factor-alpha was not significantly different between the two study groups. CONCLUSIONS: Increased IL-6 and IL-8 and decreased IL-10 levels in the peritoneal fluid may be related to pathogenesis in the endometriosis and infertility, suggesting that partially contribute to the disturbed immune regulation observed in infertili women with endometriosis.

OBJECTIVE: The results for finding the deficit in the anterior cingulate (ACC) in schizophrenic patients (SZ) have been inconsistent according to the studies that used different Stroop tasks, which is unlike the deficit in the dorsolateral prefrontal cortex (DLPFC). In order to explore for the core region that's responsible for the selective attention deficit in SZ, we examined the results of a functional neuroimaging study, which involved the performance of the Stroop task using high or low prefrontal cortex related loads in SZ. METHODS: Ten schizophrenic patients and healthy controls (HC) received functional magnetic resonance imaging (fMRI) during a Short/Long-term latency Stroop task. The changes in the neural activity were determined in well-known Stroop related regions of interest (ROIs) that consisted of the DLPFC, ACC, the parietal lobule and in the whole brain regions for both the main and interaction effects of latency, and the results of the short-term and long-term latency Stroop conditions were compared. RESULTS: The response times for both the congruency and latency effects were more prolonged in the schizophrenics than in the HC. For the congruency effect, the schizophrenics showed significantly less activation in the same site of the left DLPFC in both the short-term and long-term latency conditions, as compared with the HC. For the latency effect, the regions of the left-side language network were over- or under-activated in the schizophrenics, as compared with the HC. Any interaction effect was not found for both the behavioral and fMRI results. CONCLUSION: Our results indicate that the deficit in the left DLPFC is the core impairment of attentional processing in schizophrenics, regardless of other possible interactions such as the latency effect.

BACKGROUND: Increased left ventricular mass in patients with essential hypertension, coronary artery disease, chronic renal failure or in general population has been suggested as a useful predictor of increased cardiovascular morbidity and mortality. Many studies have reported that left ventricular mass is correlated postively with body size. Thereafter normalization of left ventricular studies, but it is uncertain which is appropriate. This study was designed to determine the appropriate method for normalization of left ventricular mass to exclude influence of body size in normal adults. METHODS: We measured left ventricular mass 100 normal adults by M-mode echocardiogram using ASE cube method without(Devereux and Reichek's method) and with correction(Devereux and Alonso's method). Left ventricular mass were normalized for body weight, height, body surface area, body surface area1.5, height2.0 and height2.7 RESULTS: 1) Left ventricular mass by Devereux and Reichek's method correlated well with that by Devereux and Alonso's method(r=1.0,p<0.001). 2) Corrected left ventricular mass correlated well with weight(r=0.64, p<0.001), height(r=0.49, p<0.05), body surface area(r=0.53, p<0.01) and body mass index(r=0.58, p<0.001). 3) Correlation coefficients of left ventricular mass/weight with weight, of ventricular mass/height with height, of ventricular mass/height2.0 with height, of ventricular mass/height2.7 with height, of ventricular mass/body surface area with body surface area and of ventricular mass/body surface area1.5 with body surface area were 0.12, -0.05, -0.29, -0.42, 0.13 and -0.11 respectively. 4) Peak systolic wall stress correlated with age and left ventricular mass, but end systolic wall stress did not correlated with left ventricular mass. CONCLUSIONS: The current indexation method of left ventricular mass for height may reduce the variability associated with body size. Furthermore, it could be used reliably in normal Korean adults.

Many reproductive women, at least 20-50%, suffered from premenstrual syndrome and 2-8% of them have premenstrual dysphoric disorder(PMDD). Prospective daily records during 2 menstrual cycles are required to differentiate PMDD from other various similar conditions such as concurrent psychiatric or medical diseases or their premenstrual magnification and also to determine the efficacy of treatment. The etiology of PMDD is largely unknown. Recently as several randomized placebo-controlled trial in women with PMDD have reported the efficacy of serotonin reuptake inhibitors(SSRIs), SSRIs have been preferred to other treatment regimens though response rates to SSRIs were variable with high placebo response rate and though their long-term and preventive effect were not yet determined.

PURPOSE: This study was done to identify the state of internet addiction and to investigate the relationships among internet addiction, depression and suicidal ideation in adolescents. METHOD: Participants were 1,670 high school students in an urban city. The Internet Addiction Scale was used to measure internet addiction, the DISC-MDD-SQ was used to measure depression, and the Suicidal Ideation Questionnaire-JR was used to measure suicidal ideation. RESULT: 38.1% of participants were perceived to be in the early stages of internet addiction and 1.5% reported heavy addiction. Overall the internet addiction scale score was 37.57(+/-12.52). The differences of internet addiction in sample characteristics were found to be significant in rank in class. The differences in DISC-MDD-SQ and IAS scores among the states of internet addiction were statistically significant. The level of internet addiction correlated positively to the level of depression and suicidal ideation. CONCLUSION: Based upon these findings, there were significant positive correlations among Internet addiction, depression, and suicidal ideation in adolescents. As schools are often the first line for the identification of potential life-threatening behaviors, nurses, especially school-based health professionals, need to be cognizant of measures and procedures for the assessment of Internet addiction, depression, and suicidal ideation.

PURPOSE: To analyze the baseline clinical factors and medication treatment strategy used in cases with medication treatment failure of benign prostatic hyperplasia (BPH). METHODS: From January 2006 to December 2009, 677 BPH patients with at least 3 months of treatment with medication were enrolled. We analyzed clinical factors by medication failure (n=161) versus maintenance (n=516), by prostate size (less than 30 g, n=231; 30 to 50 g, n=244; greater than 50 g, n=202), and by prostate-specific antigen (PSA) levels (less than 1.4 ng/mL, n=324; more than 1.4 ng/mL, n=353). RESULTS: Age, combination medication rate, PSA, and prostate volume were statistically different between the medication treatment failure and maintenance groups. By prostate size, the PSA and medication failure rates were relatively higher and the medication period was shorter in patients with a prostate size of more than 30 g. The combination medication rate was higher in patients with a prostate size of more than 50 g. The medication failure rate and prostate volume were higher in patients with a PSA level of more than 1.4 ng/mL. However, the combination treatment rate was not significantly different in patients with a PSA level lower than 1.4 ng/mL. Suggestive cutoffs for combination medication are a prostate volume of 34 g and PSA level of 1.9 ng/mL. CONCLUSIONS: The clinical factors associated with medication failure were age, treatment type, and prostate volume. Combination therapy should be considered more in Korea in patients with a PSA level higher than 1.4 ng/mL and a prostate volume of between 30 and 50 g to prevent medication failure.

Objectives: ：Although subclinical depression symptoms are associated with suicidal idea, most research have focused on clinical depression such as major depressive disorder or dysthymia. The aim of this study is to investigate network structure of depressive symptom and to reveal which symptoms are associated with suicidal ideation. Methods: ：We used part of data from the seventh Korea National Health and Nutrition Examination Survey. Participants were between 19 and 65 years of age (N=8,741). Network analysis with Isingfit model is used to reveal network structure of depressive symptoms and most central symptom and edges assessed by patient health questionnaire (PHQ-9). Results: ：The most two central symptoms were psychomotor activity and suicidal ideation. The strongest edge was psychomotor activity-suicidal ideation. Suicidal ideation also has strong association with depressive mood and worthlessness. Conclusions ：These results suggest that psychomotor activity and suicidal ideation can serve as treatment target for subclinical depression and psychomotor activity, worthlessness and depressed mood may be important factor for early intervention of suicidal ideation.

Arthroscopy has become an attractive modality in the diagnosis and treatment of joint diseases in toy breed dogs. However, the application of arthroscopy is limited by small joint space. Our objective was to evaluate the efficacy of a stifle lever for joint distraction during stifle arthroscopy in toy breed dogs. Paired stifles (n = 32 each) collected from 16 cadavers of toy breed dogs were randomly assigned to one of two groups: the stifle lever group or the external manipulation group. All stifles underwent arthroscopic cranial cruciate ligament transection, and the visualization of the medial meniscus was evaluated. Medial meniscal release (MMR) was then performed. Following arthroscopic examination, the success rates of MMR and damages of tibial and femoral cartilages were evaluated. Visualization of the medial meniscus was significantly better, and meniscal probing was significantly easier, in the stifle lever group than in the external manipulation group (p = 0.001). There were no significant differences between groups for MMR success or articular cartilage damage. Using the stifle lever on arthroscopic examination improved visualization and probing on the medial meniscus in toy breed dogs. The stifle lever can be used as a good modality in assessing medial meniscal pathology in toy breed dogs.

PURPOSE: Conflicting results have been reported for western populations on associations of serum insulin-like growth factor I (IGF-I) and major IGF-binding protein-3 (IGFBP-3) with the risk of prostate cancer. However, few data have been available for oriental populations. We undertook a matched case-control study in a low-risk Korean population to extend our knowledge about potential associations. MATERIALS AND METHODS: Serum IGF-I and IGFBP-3 levels were determined for 330 men (165 cases and 165 healthy age-matched controls). Conditional logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for the association between plasma IGF levels and prostate cancer. We also investigated the potential influence of the associations according to clinical risk for advanced disease at diagnosis. RESULTS: We noted that the risks of prostate cancer were unrelated to the IGF-1 level and IGF-I/IGFBP-3 molar ratio. In contrast, a strong inverse association was observed between IGFBP-3 levels and the risk for prostate cancer. Men in the highest quartile of IGFBP-3 levels had a 71% reduced risk of prostate cancer compared with men in the lowest quartile (OR=0.29, 95% CI: 0.11-0.64, P(trend)<0.001). Subgroup analysis revealed a significant inverse association between plasma IGFBP-3 and the likelihood of a high risk prostate cancer. CONCLUSIONS: Plasma IGFBP-3 levels were inversely associated with the risk of prostate cancer and the likelihood for high-risk disease, suggesting that IGFBP-3 plays a protective role against prostate cancer in the Korean population.
