New Cervicography, a Pap smear adjunct test, is an innovative cervical cancer surveillance system. It is a relatively new technique in which a photograph of the cervix is obtained without the aid of colposcope after application of 5% acetic acid. The purpose of this study was to investigate the role of New Cervicography in diagnosis of cervical cancer. Pap smear and cervicogram data were obtained from 143 patients who visited the Department of Obstetrics and Gynecology, Chungnam National University Hospital from September 1996 to May 1997. Histologic specimens were obtained from patients in whom abnormalities were detected by either Pap smear or cervicogram. Specimens were taken either by colposcopically directed biopsy or large loop excision af the transformation zone. (continue)

Anthocyanidins, the aglycones of anthocyanins, are natural colorants belonging to the flavonoid family. Cyanidin is one of the anthocyanidins, used for their antioxidant properties. Furthermore, previous studies have shown anthocyanidin-rich material extracts or aglycone form inhibit growth and induce apoptosis of cancer cells. But, Tumor metastasis is the most important cause of cancer death, and various treatment strategies have targeted on preventing the occurrence of metastasis. This study investigated the effects of cyanidin on metastasis processes, including motility, invasion and activity of MMP-2 and MMP-9 in MDA-MB-231 human breast cancer cell lines. We cultured MDA-MB-231 cells in presence of various concentrations 0, 5, 10 and 20 micrometer of cyanidin. The cell motility was significantly decreased dosedependently in cells treated with cyanidin (p < 0.05) and cyanidin treatment caused the significant suppression of the invasion (p < 0.05). MMP-2 and MMP-9 activities, and MMP-9 mRNA express were not affected by anthocyanin treatment. In conclusion, cyanidin inhibits cell motility, invasion in MDA-MB-231 human breast cancer cell lines.

OBJECTIVES: Suicide is one of the most common causes of deaths in correctional institutions. This study aimed to examine the characteristics of suicide attempts and its related psycho-social factors in correctional institutions. METHODS: This study examined the characteristics of 101 suicide attempts from 2006 to 2007 in the two regional correctional headquarters. Thirty-seven male inmates (43 suicide attempts) and 40 matched controls were included in interviews and reviews of personal records. Psychiatric illnesses were examined using the Structured Clinical Interview for DSM-IV and medical outcomes of their suicide attempts with the Lethality Scale of Diagnostic Interview for Genetic Studies. RESULTS: Over a half of suicide attempts occurred in solitary cells and the most common method was hanging. Medically, 70% of the suicide attempts were more than severe. Poor social support, a lifetime history of suicide attempts, and incarceration were associated with suicide attempts. Additionally, psychiatric illnesses were more likely to increase the risk of suicide. CONCLUSION: This study implies that mental health issues and monitoring systems are important to reduce suicides in the correctional system. Regular checks and management of suicide risk and mental illness are crucial to prevent suicide in correctional institutions.

The Korea Food and Drug Administration (KFDA) revised the Health Functional Food Act in 2008 and extended the form of health functional foods to general food types. Therefore, this study was performed to investigate consumers' perceptions of the expanded form of health functional food and to predict consumption patterns. For this study, 1,006 male and female adults aged 19 years and older were selected nationwide by multi-stage stratified random sampling and were surveyed in 1:1 interviews. The questionnaire survey was conducted by Korea Gallup. The subjects consisted of 497 (49.4%) males and 509 (50.6%) females. About 57.9% of the subjects recognized the KFDA's permission procedures for health functional foods. Regarding the health functional foods that the subjects had consumed, red ginseng products were the highest (45.3%), followed by nutritional supplements (34.9%), ginseng products (27.9%), lactobacillus-containing products (21.0%), aloe products (20.3%), and Japanese apricot extract products (18.4%). Opinions on expanding the form of health functional foods to general food types scored 4.7 points on a 7-point scale, showing positive responses. In terms of the effects of medicine-type health functional foods versus generic health functional foods, the highest response was 'same effects if the same ingredients are contained' at a rate of 34.7%. For intake frequency by food type, the response of 'daily consistent intake' was 31.7% for capsules, tablets, and pills, and 21.7% for extracts. For general food types, 'daily consistent intake' was 44.5% for rice and 22.8% for beverages, which were higher rates than those for medicine types. From the above results, consumers had positive opinions of the expansion of health functional foods to generic forms but are not expected to maintain accurate intake frequencies or amounts. Thus, continuous promotion and education are needed for proper intake of generic health functional foods.

BACKGROUD/OBJECTIVES: This study was conducted in order to investigate the effect of peanut sprout extracts (PSE) on health indices in overweight and obese women (BMI > or = 23 kg/m2). SUBJECTS/METHODS: Subjects were divided into three groups by double-blind randomized trial; the Placebo group (n = 15) and the Low PSE group (2.6 g PSE/day, n = 15), and the High PSE group (5.8 g PSE/day, n = 15). Subjects consumed 12 capsules per day, three times a day, 30 min before meals, for 4 weeks. Anthropometric data, blood biochemical variables, and dietary intake were evaluated before and after the experiments. RESULTS: In the Low and High PSE group, the waist circumference showed a significant decrease between pre- and post-test. In the Low PSE group, the reduction of systolic blood pressure between pre- and post-test was statistically significant. Serum LDL or triglyceride levels in both Low and High PSE groups were significantly decreased, and serum alanine transaminase and aspartate transaminase were significantly decreased only in the Low PSE group. The parameters regarding erythrocyte and leucocyte counts showed no significant differences between pre- and post-test among groups, which suggested the safety of intake of peanut sprouts as a dietary supplement. CONCLUSIONS: This study indicates that PSE supplementation improves abdominal obesity and overall health indices. Therefore, an appropriate amount of peanut sprouts may be a plausible effective agent for obesity and obesity related health problems in obese women.

This study attempted to investigate the effects of resveratrol on the differentiation of adipocytes. After cells were treated with various concentrations of resveratrol (0, 10, 20, and 40 micromol/L), adipocyte proliferation, the protein expression of transcription factors, and MMPs' activities were determined. Cell proliferation was inhibited more within 4 days of incubation (P < 0.05), and lipid accumulation in adipocyte was significantly inhibited by 93.8%, 92.4% and 91.5%, respectively, after two days of 10, 20, and 40 micromol/L resveratrol treatment (P < 0.05). Six days of incubation with the three resveratrol concentrations caused a significantly decreases of 63%, 59.9%, and 25.1% GPDH activity as a dose-dependent response. The triglyceride concentration also decreased significantly with the increase of resveratrol concentration (P < 0.05). The protein expression of CCAAT/enhancer-binding protein (C/EBPbeta) was decreased significantly by 56% and 30% while PPARgamma was significantly reduced by 57% and 15% with resveratrol treatments of 20 and 40 micromol/L, respectively (P < 0.05). The protein expression of C/EBPalpha was decreased by 83%, 74%, and 38% to increased dosage levels, with significance determined for this decrease from 20 micromol/L of resveratrol. The protein expression of fatty acid binding protein (FABP4) was decreased significantly by 88%, 72%, and 46% with the increase of resveratrol concentration. The activity of MMP-2 was decreased significantly by 84%, 70%, and 63% while MMP-9 activity was decreased significantly by 74%, 62%, and 39% with the increased resveratrol concentrations of 10, 20, and 40 micromol/L, respectively (P < 0.05).

OBJECTIVES: Using two stimuli, this study was designed to evaluate variations of P300 in relations to reaction time of pressing the button for target tones in patients with schizophrenia. METHODS: The auditory oddball paradigm was used for the patients (N=22) and normal controls (N=23). The two stimuli were composed of target (20%, 2000 Hz, 75 dB) tone and standard (80%, 1000 Hz, 75 dB) tone, with 2 sec inter-stimulus interval, 50 msec duration and 10 msec rise or fall time. In each subject, P300s were acquired for both fast reaction time (FRT) and slow reaction time (SRT) to target response. RESULTS: P300 amplitude in patients with schizophrenia was lower than controls across FRT and SRT (p<0.001), but P300 latency was not delayed (p>0.8). In this study, even though the reaction time for the button pressing task might be faster in patients with schizophrenia (p<0.1), the P300 to FRT in patients with schizophrenia was lower than the P300 to SRT in controls (p<0.01). CONCLUSION: These results suggest that the lower P300 in patients with schizophrenia might be due to cognitive dysfunction and the patient's performance in reaction time for pressing buttons, both independently. Thus, P300 as well as reaction time may be used to further explore a variety of domains of cognitive function.

BACKGROUD/OBEJECTIVES: This study aims to find out the effects of peanut sprout extracts on weight controls and protein expressions of transcription factors related to adipocyte differentiation and adipocytokine in rats under high-fat diets. MATERIALS/METHODS: Four week-old Sparague-Dawley (SD) were assigned to 4 groups; normal-fat (NF) diets (7% fat diet), high-fat (HF) diets (20% fat diet), high fat diets with low peanut sprout extract (HF + PSEL) diet (20% fat and 0.025% peanut sprout extract), and high fat diets with high peanut sprout extract (HF + PSEH) diet (20% fat and 0.05% peanut sprout extract). Body weight changes, lipid profiles in adipose tissue, and the mRNA protein expressions, such as peroxisome proliferator-activated receptor gamma (PPARgamma), CCAAT element binding protein alpha (C/EBP alpha), leptin, and adiponectin, were determined. RESULTS: After 9 weeks of feeding, the HF + PSEH group had significantly less weight gains than the HF group (P < 0.05). However, the total dietary intakes or food efficiency ratios among groups were not significantly different. The weight of epididymal fat in HF + PSEH group, 3.61 +/- 0.5 g, or HF + PSEL group, 3.80 +/- 0.7 g, was significantly lower than the HF group, 4.39 +/- 0.4g, (P < 0.05). Total lipids and total cholesterol in adipose tissue were significantly decreased in HF + PSEH group compared to those in the HF group, respectively (P < 0.05). PSEH supplementation caused AST and ALT levels to decrease when it compared to HF group, but it was not statistically significant. The protein expression of PPARgamma in HF + PSEH group was significantly lower than the HF group (P < 0.05). Comparing with the HF group, the protein expression of adiponectin in HF + PSEH group was significantly increased (P < 0.05). The protein expressions of C/EBP alpha and leptin in HF + PSEH group were lower than the HF group, but it was not statistical significant. CONCLUSIONS: In conclusion, peanut sprout extract has anti-obesity effect by lowering the expressions of PPARgamma which regulates the expression of adiponectin.

In this study, 342 grade 4-6 elementary school students in Gyeonggi-do were recruited to determine their readiness to change food safety behavior and to compare their food safety knowledge and practices by the stages of change. The subjects were divided into three stages of change; the percentage of stage 1 (precontemplation) was 10.1%, the percentage of stage 2 (contemplation and preparation) was 62.4%, and that of stage 3 (action and maintenance) was 27.5%. Food safety knowledge scores in stage 3 (4.55) or stage 2 (4.50) children were significantly higher than those in stage 1 children (4.17) (P < 0.05). The two food safety behavior items "hand washing practice" and "avoidance of harmful food" were significantly different among the three groups (P < 0.05). Stages of change were significantly and positively correlated with food safety knowledge and practice. Age was significantly and negatively correlated with the total food safety behavior score (r = -0.142, P < 0.05). The most influential factor on the stage of change was a mother's instruction about food safety (P < 0.01).

Nonsteroidal antiinflammatory drugs(NSAIDs) are known as clinically effective agents for treatment of inflammatory diseases. Inhibition of cyclooxygenase has been thought to be a major facet of the pharmacological mechanism of NSAIDs. However, it is difficult to ascribe the antiinflammatory effects of NSAIDs solely to the inhibition of prostaglandin synthesis. Human neutrophil elastase (HNElastase; HNE, EC 3.4.21.37) has been known as a causative factor in inflammatory diseases. To investigate the specific relationship between HNElastase inhibition and specificity of molecular structure of several NSAIDs, HNElastase was purified by Ultrogel AcA54 gel filtration, CM-Sephadex ion exchange, and HPLC (with TSK 250 column) chromatography. HNElastase was inhibited by aspirin and salicylate in a competitive manner and by naproxen, ketoprofen, phenylbutazone, and oxyphenbutazone in a partial competative manner, but not by ibuprofen and tolmetin. HNElastase-phenylbutazone-complex showed strong Raman shifts at 200, 440, 1124, 1194, 1384, 1506, and 1768 cm(-1). The Raman bands 1194, 1384, and 1768 cm(-1) may represent evidences of the conformational change at -N=N-phi radical, pyrazol ring, and -C=O radical of the elastase-drug complex, respectively. Phenylbutazone might be bound to HNElastase by ionic and hydrophobic interaction, and masked the active site. Inhibition of HNElastase could be another mechanism of action of NSAIDs besides cyclooxygenase inhibition in the treatment of inflammatory diseases. Different inhibition characteristics of HNE-lastase by NSAIDs such as aspirin, phenylbutazone-like drugs and ineffective drugs could be important points for drawing the criteria for appropriate drugs in clinical application.
