This study was done to compare the nutritional status of antioxidant vitamins between college women smokers and nonsmokers. Dietary intakes and serum levels of antioxidant vitamins were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Dietary intakes of vitamin A and C were determined by a quick and convenient dietary intake method. Serum vitamin C level was measured by 2,4-dinitrophenylhydrazine method and serum levels of vitamin A and E were measured by HPLC. The mean A intake of nonsmokers and smokers was 504.3 microgram R.E./day and 450. 4 microgram R.E./day and the mean vitamic C intake of nonsmokers and smokers was 51.6mg/day and 50.2mg/day, reapectively. There was no difference in the dietary intakes of antioxidant vitamins between smokers and nonsmokers. The serum vitamin A level, 0.71mg/1 in nonsmokers was not significantly different from that of 0.74mg/1 in smokers. However, the serum vitamin C level, 7.94mg/1 in smokers was 15% lower(p<0.05) than that of 9.30mg/1 in nonsmokers. The serum vitamin E level, 18.15mg/1 in smoders was also 34% lower(p<0.05) than that of 27.58mg/1 in nonsmokers. There was no significant correlation between dietary intakes and serum levels of vitamin A and C for both smokers and nonsmokers. These results suggest that cigarette smokers need more dietary intakes of vitamin C and E than do nonsmokers to reach the same serum level.

Perigraft seroma is uncommon complication of polytetrafluoroethylene(PTFE) grafts applied as an arteriovenous shunt for hemodialysis. It is a collection of clear, sterile fluid confined to nonsecretory fibrous pseudomembrane, most commonly localized around the middle and distal portion of graft. The possible etiologic factors of perigraft seroma include poor graft incorporation, mechanical graft damage caused by alcohol and povidone-iodine, intraoperative streching of the graft, variations in quality control at the time of manufacture and contributing factors such as anemia and coagulopathy in uremia. The best strategy for management of perigraft seroma is not clear. spiration or drainage alone is not effective, and some authors advocate graft removal. We report a case of perigraft seroma around arterial end of PTFE graft along with a brief review of the literatures.

PURPOSE: This study was intended to investigate the migrating motor complex (MMC) changes after ileal bypass in ex-vivo mouse models. METHODS: Partial (side-to-side) and total bypass (occlusion of proximal part of bypassed loop) were performed on ileums of female Institute of Cancer Research mice. After 2 and 4 weeks, the bypassed segments were harvested and MMCs were recorded at 4 different sites ex-vivo. Amplitude, duration, interval, direction of propagation, and the area under the curve (AUC) of MMCs were measured and compared to those of the controls. RESULTS: In control mice (n = 7), most MMCs propagated aborally (91.1%). After 2 weeks of partial bypass (n = 4), there was a significant decrease in both amplitude and AUC, and orally-propagating MMCs increased significantly (45%, P = 0.002). Bidirectional MMCs (originating in the bypassed loop and propagating in both directions) were also observed (10%). The amplitude of the MMCs remained decreased at 4 weeks after partial bypass (n = 4), and neither the AUC nor the direction of propagation showed significant changes compared to 2 weeks. Similarly, in the total bypass model, both the amplitude and AUC of the MMCs decreased significantly compared to controls. In contrast to partial bypass, 95% of the MMCs within the bypassed loop propagated aborally after 2 weeks (n = 6), which was similar to the control state. After 4 weeks (n = 5), however, MMCs either lost their temporal relationship or completely disappeared. CONCLUSION: The changes in propagation direction of the MMCs in the partially bypassed loop may contribute to stagnation of bowel contents and the development of blind loop syndrome.

In order to investigate the dietary intakes and physical characteristics in college women smokers, interviews using questionnaires were done on 33 smokers and 42 nonsmokers residing in seoul area. General living habits, dietary habits, food consumption frequency and nutrient intake by quick estimation were investigated through direct interviews with subjects. Subjects height, weight and blood pressure were measured, and body fat percentage were statistically analyzed using Bio-electrical Impedence Fatness Analyzer(GIF-891). All data were statistically analyzed by SAS PC package program ; percentage or mean and standard error were examined for each item, and the significant difference was evaluated by chi-square test or Student's t-test at alpha=0.05. In the analysis of taste and food preference, smokers consumed larger amount of alcohol and coffee than nonsmokers ; they also disliked sweet taste. The results of food consumption frequency data also showed that smokers consumed less fish, milk and fruits but consumed more instant foods than nonsmokers. As a result of anthropometric measurements, height, age, and body fat percentage showed no difference, but there was a significant difference in weight, BMI, systolic blood pressure, and diastolic blood pressure. Energy intake in nonsmokers was 1640 kcal/day(CHO : Pro : Fat=66.0 : 14.7 : 19.3), in smokers. Intakes of calcium, iron, vitamin C, vitamin A, vitamin B1, vitamin B2, and niacin in smokers were not significantly different from those of nonsmokers.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.

BACKGROUND: Hypothermia is a condition that can lead to serious complications and even to death in newborn. Although the temperature control is essential in neonatal care, it is often neglected during urgent transfer from local private hospitals. The purpose of this study is to evaluate the incidence and clinical outcomes of transfer induced neonatal hypothermia. SUBJECTS AND METHOD: In this retrospective study, subject is limited to transferred outborn babies with age less than 24 hours from June 1996 to May 1999. A total of 3,086 patients were admitted in NICU during the study period and inborn and outborn babies were 1,743(56%) and 1,343(44%) respectively. Among the 1,343 outborn babies, 212 babies were transferred from the private hospital within 24 hours of birth and were eligible for the study. Rectal temperature on arrival, transfer time, birth weight, gestational age, initial arterial gas study, and clinical outcome were compared. Statistical analysis has been done with chi-sqaure test and multiple logistic regression analysis. RESULTS: There were 84 cases(39.6%) hypothermia(<36degrees C> among the 212 babies and the rate of hypothermia in transfered babies have not decreased over the study period. There were significantly more hypothermia in lower gestational age (less than 28 weeks) and lower birth weight (less than 2,000gm) caused hypothermia significantly more than normal gestational age or normal range of birth weight. And time interval (less than 12 hour) from birth to arrival at emergency department was also significant factor in hypothermia. The mortality rate was three fold higher in hypothermia than normothermic or hyperthermic babies. CONCLUSION: This study shows that hypothermia during neonate transportation is a major cause of neonatal mortality and morbidity in prehopital care. Body temperature control during transport of neonates under 24 hours of age should be emphasized for the better outcome of treatment.
