OBJECTIVES: The analysis of heart rate variability (HRV) is a useful non-invasive tool to investigate the autonomic nerve function. Previous studies on the relationship between HRV and depression have been reported controversial results. Similarly, the correlation between the serum lipids and depression is debatable. The purpose of this study is to examine the relationship between heart rate variability, lipid profile and depression. METHODS: A total of 42 patients with major depressive disorder (MDD) and 32 age and sex-matched normal subjects who had no previous history of major medical and mental illnesses were recruited for this study. A structured-interview was used to assess the general characteristics and psychiatric illness. HRV measures were assessed by time-domain and frequency-domain analyses. Psychological symptoms were measured using the Hamilton rating scale for anxiety (HAM-A), Hamilton rating scale for depression (HAM-D). In addition, the evaluation for lipid profile was performed by blood test. RESULTS: In serum lipid profile test, MDD group showed higher cholesterol (197.68+/-42.94 mg/dL vs. 176.85+/-34.68 mg/dL, p=0.044), TG (139.45+/-92.54 mg/dL vs. 91.4+/-65.68 mg/dL, p=0.018), LDL (130.03+/-33.18 vs. 106.62+/-27.08, p=0.004) level than normal control group. In HRV time domain analyses, the standard deviation of the NN interval (SDNN) was decreased in MDD group than normal control group, but was not significant (32.82+/-14.33 ms vs. 40.36+/-21.40ms, p=0.078). ApEn (Approximate Entrophy) was significantly increased in MDD group than normal control group (1.13+/-0.11 vs. 0.91+/-0.18, p<0.001). ApEn was correlated with LDL level (r=0.277, p=0.028), HAM-D scores (r=0.534, p<0.001) and HAM-A scores (r=0.470, p<0.001). CONCLUSION: MDD patients showed increased ApEn, one of the HRV measurement. And this ApEn was correlated with LDL, HAM-D and HAM-A scores. In this study, the analysis of ApEn would be a useful test of MDD.

Localized fibrous tumor is an uncommon submesothelial origin tumor found in pleura most commonly. Sixty five-year-old man with right lower quadrant pain was admitted. He was treated with resection of tumor and was diagnosed as localized fibrous tumor of pelvic cavity. He is now being followed up without any evidence of recurrence for 34 months. This case is presented with reviewing references.

OBJECTIVES: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. METHODS: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. RESULTS: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. CONCLUSIONS: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

PURPOSE: To identify effects of menstrual attitude, premenstrual syndrome, and stress response on quality of life of nursing students. METHODS: Subjects were 135 nursing students who agreed to participate in this study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation, and stepwise multiple regression. RESULTS: Premenstrual syndrome, younger than 20 years of age, and habit of eating bland food in everyday life were factors influencing quality of life of nursing students. These factors accounted for 17.6% of quality of life. Premenstrual syndrome toward quality of life was the most influential factor. CONCLUSION: Premenstrual syndrome is the most significant factor affecting the quality of life of nursing students. To increase their quality of life, it is important to develop and apply educational programs using factors influencing quality of life of the nursing students. Results of this study will be useful as basic data for improving quality of life of nursing students. Additional study is needed to test its effect in the future.

BACKGROUND: Nitrous oxide exposure for long periods during gestation causes the increased fetal wastage, growth retardation, morphological abnormalities in rodents. Most studies have explained deleterious effects of nitrous oxide on postimplantation embryo development. The aim of this study was to evaluate the effects of nitrous oxide on embryo after the fertilization in superovulated BALB/c mice. METHODS: Pregnant mice were exposed to 70% nitrous oxide in oxygen for 6, 12 and 24 hours on the day of gestation, and 2-cell stage embryos were cultured to blastocyst. Reproductive data were determined at cesarean section on 16th day of gestation based on embryonic developmental failure in vitro by 24 hours nitrous oxide. The protective effects of folinic acid or methionine against inhibition of 2-cell embryo development were also evaluated. RESULTS: Blastocyst development was significantly lower in 12 and 24 hours nitrous oxide group than in the control and 6 hours nitrous oxide group. The pregnancy rate and the mean number of implantations were significantly lower in 24 hours nitrous oxide group than in the control. No significant differences in percentage of the living fetus, the dead fetus, the resorption per implantation, the mean fetal weight and the crown-rump length were observed between nitrous oxide group and control group. There was no significant difference between the nitrous oxide group and the nitrous exposed group receiving methionine and folinic acid. CONCLUSIONS: The exposure to high concentration of nitrous oxide for a long time after the fertilization in mice may be possibility of the early abortion of embryos, whereas there is not any influence on fetus after the implantation.

I n some patients, eosinophilic gastroenteritis(EG) occurs in those with food allergy. We experienced a non-atopic asthmatic who had an EG associated with food allergy to fish and eggs, and blood eosinophilia. A skin prick test and RAST to causative food allergens showed a negative result. A fiber-optic endoscopic biopsy from the gastric mucosa showed an intense eosinophilic infiltration. We could find symptomatic improvement and a disappearance of eosinophilic infiltration in gastric mucosa after complete avoidance from the causative food and oral cortcosteroid. It was suggested that fiber-optic endoscopic biopsy might be needed to identify coexisting EG if an allergic patient with blood eosinophilia complains of severe gastrointestinal symptoms.
