<P><B>Abstract</B></P> <P>Heme oxygenase-1 (HO-1) has an anti-inflammatory action in acute pancreatitis (AP). However, its mechanism of action and natural compounds/drugs to induce HO-1 in pancreas are not well understood. In this study, we investigated the regulatory mechanisms of HO-1 during AP using desoxo-narchinol-A (DN), the natural compound inducing HO-1 in the pancreas. Female C57/BL6 Mice were intraperitoneally injected with supramaximal concentrations of cerulein (50 μg/kg) hourly for 6 h to induce AP. DMSO or DN was administered intraperitoneally, then mice were sacrificed 6 h after the final cerulein injection. Administration of DN increased pancreatic HO-1 expression through activation of activating protein-1, mediated by mitogen-activated protein kinases. Furthermore, DN treatment reduced the pancreatic weight-to-body weight ratio as well as production of digestive enzymes and pro-inflammatory cytokines. Inhibition of HO-1 by tin protoporphyrin IX abolished the protective effects of DN on pancreatic damage. Additionally, DN treatment inhibited neutrophil infiltration into the pancreas via regulation of chemokine (C-X-C motif) ligand 2 (CXCL2) by HO-1. Our results suggest that DN is an effective inducer of HO-1 in the pancreas, and that HO-1 regulates neutrophil infiltration in AP via CXCL2 inhibition.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Desoxo-narchinol-A (DN) is a natural compound of HO-1 inducer in pancreas. </LI> <LI> Mechanism of DN-induced HO-1 is mediated by MAPK/Activator Protein-1/HO-1 signaling. </LI> <LI> DN-induced HO-1 blocks neutrophil infiltration into pancreas via inhibition of CXCL2. </LI> <LI> DN inhibits cerulein-induced acute pancreatitis (AP) and AP-associated lung injury. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Objectives : To analyze the characteristics of the pediatric patients who visited the emergency room and outpatient department of secondary hospital in order to properly guide pediatric patients to use emergency room and raise the efficiency Methods : The authors investigated and analyzed sex, age, visit day, visit time, length of stay, hospitalization and diagnostic entities of the pediatric patients who visited the emergency room and outpatient department of Wallace Memorial Baptist Hospital from January 2003 to December 2005 in a retroactive approach with their medical records. Results : For the three years, the number of total patients who visited the emergency room was 56,051 and among them, the number of pediatric patients was 7,490 (13.4%). The age group of 1 to 2 years was the largest with 2,488 (33.2%). The male to female ratio was 1.34:1. Sunday was the day of the week that the largest number of patienst visited with 2,375 (31.7%) and nearly half (48.4%) of the patients visited the emergency room during the weekend. The time when the most patient visited the emergency room was between 8 pm to 12 am. Regarding the length of stay, the highest number of patients (65.0%) stayed in the emergency room for on hour or less, and the average length of visit was 1.5 hours, which was rather short. Most patients (68.8%) left the hospital after taking simple physical examination and procedure(prescription). The most frequent diagnoses for the pediatric patients who visited the emergency room were acute pharyngitis (26.0%), acute gastroenteritis (20.7%), fever (6.6%). During the same period, the total number of pediatric patients who visited the outpatient department was 125,513. The age group of 3 to 5 was the largest with 36,041 (28.7%). The male to female ratio was 1.34:1. 6.0% of total outpatients required treatment in a hospital. Most frequent diagnoses of the outpatients were asthma (24.4%), pneumonia (12.0%), vaccination (8.7%), febrile convulsion (8.4%), acute pharyngitis (6.6%), acute gastroenteritis (5.8%). Conclusion : It is considered that a large number of pediatric patients still have used emergency room for treatment of simple and mild diseases instead of visiting outpatient department and/or primary hospital. Thus further efforts are required to properly guide pediatric patients to use emergency room and to raise the efficiency of their use.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

DW-166HC (^(166)Holmium (^(166)Ho)-Chitosan complex) is a new radiopharmaceutic anticancer agent with a broad anti-tumorigenic spectrum, especially against human hepatic cancer. DW-166HC was evaluated for the appearance of micronucleus in polychromatic erythrocytes (PCEs) of mouse bone marrow cells after subcutaneous arid intravenous single administration. Bone marrow cells were prepared at 24 hr and 48 hr after DW-166HC-I (^(165)Ho-Chitosan complex : cold compound) administration and at 24 hr, 72 hr and 2 weeks after DW-166HC (^(166)Ho-Chitosan complex : hot compound) administration. The results showed there was no statistically significant increase of the numbers of PCEs with micronucleus in all DW-166HC-I administered groups compared with a negative control group but there was statistically significant increase of the numbers of PCEs with micronucleus at 24 hr arid 72 hr in all DW-166HC administered groups, which was recovered after 2 weeks from the drug administration. The results also showed the ratio of normochromatic erythrocytes (NCEs) to PCEs of all DW-166HC-I administered groups was not significantly different from that of a negative controi group but there was significant difference of this ratio at 24hr and 72 hr in all DW-166HC administered groups compared with that of negative group, which was also recovered after two weeks from the drug administration. These results suggested that DW-166HC-I may not cause any chromosomal damage but DW-166HC has in vivo mutagenic potential because of its radioactivity.

Load distribution in group piles is an important matter of consequence for the safe design and the economical design. In the group piles, the model tests were to investigate the effects on spacing-to-diameter ratio of pile, number of piles and arrangement of the pile. The tops of pile were all set to rotate freely. This paper considered the load distribution by the location of the pile as compared the behavior of group piles with single pile. For a three row pile group at 3D spacing, the measured individual row distributions were 35~38%(lead), 32∼34%(middle) and 27∼30%(tail). This results were compared very favorably to those by McVay et al(1995). The shadowing effect for the parallel direction of lateral loading appears to be more significant than the one for the perpendicular direction of lateral loading.

In this study, we designed the microfluidic device system based on the separation membrane for generating monodisperse emulsion droplets with diameters ranging from hundreds of nanometers to several micrometers. To generate fine droplets, T-junction and flow-focusing geometry are integrated into the microfluidic channel. Also put the membrane into the microfluidic device to make droplets effectively. PDMS devices can be easily, quickly, and inexpensively fabricated with superb resolution. However, PDMS devices are swelled other organic solvent. So we could produce droplets using fluorocarbon oil. The droplet size was controlled by adjusting the flow ratio between continuous phase flow and dispersed phase flow and also membrane pore size

OSAS(obstructive sleep apnea syndrome) is becoming more and more of importance nowadays. Therefore the study concerning OSAS is very important. Most of the studies which have been reported were comparison of upper airway size and change of skeletal class Ⅰ group and skeletal class Ⅲ group respectively. But, most of the showing OSAS have pharyngeal narrowing combined with more or less distinct maxillary and mandibular deficiency. Therefore the aim of this study is to see posterior airway space and hyoid bone position in patients affected by class Ⅱ malocclusion and treated with orthognathic surgery. we measured the lines between selected upper air way landmarks on lateral cephalometric x-ray films of skeletal class Ⅱ 30 persons who had not been operated yet, were within 2 weeks after operation, were 6 months after operation. And we compared them respectively and analyzed them with pairing t-test, pearson correlation coefficient and multiple regression analysis. The results were as follows. First of all, skeletal class Ⅱ group was increased in all the level of PAS, especially PAS(MK) and PAS related to hyoid bone(H-phW, H-PhW(Me-H)) was significantly decreased within 6 months after operation but that was larger than preoperation. And then the PAS was increased after mandibular advancement surgery. While there was no significant correlation between PAS and surgical methods, there was statistical significance between PAS and a number of surgical movement. At last, the hyoid bone was advanced within 2 weeks after operation but relapsed within the follow up period. In the end of the study, it was turned out that PAS was always wider without distinction of the region after the operation and that there was significant correlation between the moving volume of hard tissues and the changing quantity of PAS( ; how much PAS was changed according to the moving degree of hard tissues). After this, to be based on the study, I consider that OSAS demands further study and that it is necessary to do more practical applications to the patients.

This study exploratory examined the relationship between auditory images and clothing style images of young consumers by their personality types, sex and clothing interest. A questionnaire was developed to measure auditory images, clothing style images, personality types, clothing interest and demographic variables. Scale items were adopted from prior studies on clothing self images and Myers-Briggs Type Indicator (MBTI) known to measure psychological types. 120 undergraduate students with diverse majors were the respondents of the empirical study. MBTI categorized respondents into one of 3 personality types, IFT (Introversion and Thinking or Feeling, n=23), EF (Extroversion and Feeling, n=73) and ET (Extroversion and Thinking, n=24). ANOVA results indicated that, among 13 auditory images measured in the study, rational, self-confident and social images were significantly different across three personality type groups. Overall, ET group showed higher level of the the auditory images. Among clothing style images, social images were significantly different. IET group showed significantly lower level of social images. In addition, respodents' age and level of clothing interest influenced auditory and clothing style images. Correlation coefficients indicated that there were significant relationships between most auditory and clothing style images included in the study except for the self-confident image.
