To evaluate the relationship between eating behavior and neurotic trait in middle school students, the authors applied eating scale, Middlesex Hospital Puestionaire and Zung's self-reting depression scale to 419 middle school students(male : 187, female : 232) in Taegu city in 1993. There was no significant relationship between weight devided groups. Female middle school students showed significant high scores(p<0.05) in all scales compared to male middle school students. The correlation between eating scale and the other two scales showed significant correlationship(p<0.05) Among psychosocial factors, the items related to dissatisfaction to present and future self image(each p<0.05, p<0.05), dissatisfaction to present environmental status(p<0.05) and dissatisfaction to future attitude showed significant high score in both sex. The item related to dissatisfaction to present interpersonal relationship (p<0.05) showed significant high score in male middle school students. The items related to eat consumption rate of 61-90% (p<0.05), unsatisfied to relationship with family(p<0.05), unsatisfied to childhood family atmosphere(p<0.05), unsatisfied to past self image(p<0.05) and unsatisfied to present relationship between parent(p<0.05) showed significant high score.

Infrahepatic interruption of the inferior vena cava with azygos continuation is relatively infrequent cardiovascular developmental anomaly occurring both in association with congenital heart disease and as an isolated anomaly of no hemodynamic importance. During the past 5 years, we observed 38 cases of infrahepatic interruption of IVC with azygos continuation out of 2,397 cases of congenital heart disease catheterized at Yonsei Cardiovascular Center. We conducted the study with a view point of position of the heart and abdominal organs and segmental analysis of the underlying congenital heart disease. We also analysed the associated exracardiac vascular anomalies The following results wer obtained: 1) The incidence of this anomaly among congenital heart disease was 1.7% and the sex ratio 1.4:1. Twenty four cases(63.1%) was below 5 years of age and 30 cases (79.0%) had cyanosis. 2) We observed 21 cases (55.2%) with the malposition of the heart and 17 cases (44.8%) with malposition of the abdominal organs. The ventricular loops revealed D-loop in 25 cases, L-loop in 5 cases and in the remaining 7 cases, it was uncertain. Eighteen showed normally related great arteries and malposition was present in another 18 cases. 3) Associatcd cardiovascular anomalics wcre as follows: right-sidcd aortic arch: 12 cases, patentductus arteriosus: 10 cases, pulmonic stenosis: 19 cases and bilateral superior vena cava: 9 cases. In conclusion, the presence of this anomaly should alert one to seek the severeintracardiac anomalies which are usually associated with it. Also, it is essential that, if any patient with this anomaly should come to thoracotomy, the azygos vein be not sacrificed.

PURPOSE: To evaluate the accuracy of CT using water as an oral contrast material in a prone position in determining the depth of tumor invasion in gastric cancer patients. MATERIALS AND METHODS: Thirty three patients(19 male, 14 female) with surgically confirmed gastric cancer were studied. We performed CT in a prone position after ingestion of 1 liter of pure water. CT findings were classified into 4 groups by the morphologic appearances of infiltrates in the perigastric fat plane :normal perigastric fat(SO), fine mottled densities(S1), irregular aggregated or linear densities(S2) and direct extension and invasion of tumor into contiguous structures(S3). Also we prospectively compared the CT staging with pathologic T staging according to the TNM systems. RESULTS: The overall accuracy of CT staging in determining the pathologic T factor was 69.6%. As we regarded T1 and T2 lesions as one group on CT, the accuracy of CT staging was increased to 80.2% because of a limitation of CT for distinguishing T1 from T2 lesions. CONCLUSION: Prone position CT using water as an oral contrast agent is quite accurate in determining the T staging of gastric carcinoma.

The authors studied ED50 of bethanechol on the contractilities of the smooth muscles isolated from various organs of rat under the presence of atropine (a classical competitive blocker of cholinergic muscarinic receptor) or minaprine (a newly developed antidepressant drug) to investigate the peripheral anticholinergic effect of minaprine. The results were as follow: 1) There was no significant difference between ED50 of bethanechol in the control group and that under the presence of minaprine 10⁻⁸M and 10⁻⁷M in the smooth muscles isolated from the duodenum. 2) There was no significant difference between ED50 of bethanechol in the control group and that under the presence of minaprine 10⁻⁸M and 10⁻⁷M in the smooth muscles isolated from the ascending colon. 3) There was significant difference between ED50 of bethanechol in the control group and that under the presence of minaprine 10⁻⁸M and 10⁻⁷M in the smooth muscles isolated from the urinary bladder (P<0.01) 4) There was significant difference between ED50 of the atropine 10⁻⁸ and minaprine (10⁻⁸M) in the smooth muscles isolated from the urinary bladder (P<0.05).

The purpose of this study was to investigate the inhibitory role of vitamin A with respect to activation of Ito cells in fibrosis of the rat liver induced by common bile duct ligation(CBDL). The liver was examined by immunohistochemical staining for a-smooth muscle actin,the known marker of activated Ito cells, and light and electron microscopy after CBDL andCBDL with intraperitoneal injection of retinoic acid (Sigma, USA) 1 mg/Kg in 3 times per week. The results were sumrrlerized as follows: After CBDL, the bile ductules were markedly proliferated in the periportal areas extending toterminal hepatic veins. Interstitial fibrosis and inflammatory cell infiltration appeared, however,cholestasis was minimal. Retinoic acid treatment with CBDL decreased bile ductular proliferationand interstitial fibrosis compared to CBDL only. After CBDL, proliferated and activated Ito ceIs showing positive reaction in smooth muscle actin were present in the periductular andperisinusoidal areas, and areas of increased interstitial fibrosis. Activated ito cells weredecreased in number after CBDL with vitamin A treatment. Electron microscopically,intracytoplasmic fat droplets and the cytoplasmic processes of Ito cells were decreased afterCBDL. Myofibroblasts were frequently appeared in the interstitial fibrosis after CBDL. But,intracytoplasmic fat droplets of Ito cells were well preserved, and myofibroblasts were found lessfrequently after CBDL with vitamin A treatment. The results suggest that vitamin A plays an inbitory role in the activation and fibrogenesis ofIto cells after CBDL.

OBJECTIVES: Nasal continuous positive airway pressure (nCPAP) is the treatment of choice and has been shown to reduce the frequency of nocturnal respiratory events, improve sleep architecture, and decrease daytime sleepiness in patients with obstructive sleep apnea syndrome (OSAS). However, little is known about the compliance of nCPAP treatment in Korea. Our objective was to look into the nCPAP compliance and examine the factors influencing it. METHODS: We reviewed the records of one hundred and twenty consecutive patients with OSAS referred for nocturnal polysomnography with nCPAP pressure titration during the period of January 1995 through April 1999 to the Seoul National University Hospital. We performed a telephone interview and obtained data from eighty-three patients. RESULTS: In sixty patients who had accepted nCPAP treatment, twenty-six patients (43.3%) were still using nCPAP device, while thirty-four patients (56.7%) stopped using it. Fifteen patients (25%) were using nCPAP device everyday. In thirty-four patients who discontinued nCPAP use, twenty-five patients (73.5%) did within the first three months, and thirty-one (91.2%) within the first year. Significant predictor of long-term nCPAP use was the presence of subjective daytime sleepiness before nCPAP application. CONCLUSIONS: Long-term compliance with nCPAP treatment appears to be associated with the presence of subjective daytime sleepiness before nCPAP application. Long-term compliance with nCPAP may be mostly predicted from the usage pattern within the first three months of use.

A case of Epidermolysis Bullosa Dystrophica is reported with review of pathogenesis with literatures. Epidermolysis Bulloaa Dystrophica is a rare genetic disease which is characterized by the formation of blister upon the minor trauma or friction to the skin. A 7-year old boy was referred to our dept. in Aug. 1976 because of a severe bullous eruption primarily on his hands and feet. On admission tense bullae were noted on the dorsa of hands and feet which is usually serous but may be hermorhagic tendency. Soon thereafter tbis bullous lesion tend to break down into painful shallow denudation which may leave depigmented scars and milia after healing. Family history was negative for skin disorders.
