Cystic mesothelioma of the peritoneum is a rare benign neoplasm that occurs predominantly in young to middle-aged women and tends to recur locally. Pelvic viscera is the most common predilection site of cystic mesothelioma. Authors report a case of multicystic mesothelioma of the pelvic pelvic peritoneum. The pelvic ultrasonography showed a large, confluent, and thin-walled multilocular cystic mass occupying the pelvic cavity and lower abdomen. The cystic mass was flattened and elongated. Each cyst of variable size was separated by thin septa and filled with translucent fluid. Cystic mesothelioma should be included in the differential diagnosis of the cystic peritoneal masses, especially in reproductive-aged women.

We report a rescently experienced case with atypical radiologic manifestation of solid and papillary epithelial neoplasm of the pancreas in a 37 years old female patient. The tumor had heavy calcification on its capsule wall and septa. Instead of the usual encapsulated lesion with partly solid and partly cystic-hemorrhagic components, the lesion consisted of numerous fine cavitations containing air without fluid component except focal abscess fluid.

BACKGROUND: Alcohol has much effect on our lives as a taste food that people in almost all of the world generally have had. The effects of alcohol cause social problems as well as physical and psychological problems. Recently, interest about drinkirg increasingly rises as the rate of drinking accident increases in Korea. For this, our study examined the amount of alcohol consumption and early at-risk alcohol intake. METHODS: The prepared questionnaire was presented to subjects who were employees in Inchon . The anonymous, self-administered questionnaire was composed of questionnaire concerning alcohol consumption, early at-risk alcohol intake and doctor's role in drinking behaviour. RESULTS: Among 305 subjects, there were 189 (62%) men, 116 (38%) women whose mean age was 37. 9years. 87(28.5%)subjects were classified as high alcohol group and 218(71.5%) low alcohol group. High alcohol group was defined as early at-risk alcohol intake for men who were consuming 135g of alcohol per day, 630 per week and for women 90g per day, 270g per week. Low alcohol group was defined as early at-risk alcohol intake for men whose consumption was 90g per day, 450 per week and for women 45g per day, 270g per week . Mean alcohol consumption of drinker was 158.9g per week. 3 days per week people should not drink in order to avoid risk Although 54% of respondents thought doctors should ask about their drinkirg habits, only 16.4% of respondents reported ever being asked about alcohol intake on the subject. CONCLUSION: Early at-risk drinking subject in the study was much more than those suggested by NIH(National Institutes of Health). We conclude that primary care physicians should take more interest in screening, treating and preventing alcohol related problems and advise and educate patients to cut down or quit drinking.

OBJECTIVE: This study was conducted to identify 3 to 5 years of future management issues in hospital information systems (HIS). METHODS: Two rounds of interview surveys were conducted based on the sample survey of 50 managers from 28 hospital information centers utilizing the Delphi method. RESULTS: From the survey, management issues in HIS were identified in the following order: 'top management support', 'close relationship with users', 'PACS', 'disaster recovery', improving IS strategic planning'. Compared with the 1999 survey, the issues that rank within the top 10 management issues were as follows: 'top management support', 'security and control', 'close relationship with users'. Recently surfaced issues are 'disaster recovery' and 'standardization'. The issues that dropped out of the top 10 ranks were 'network management', 'recruiting and developing IS human resource'which were very fundamental issues in the initial state of the introduction of the hospital information system. CONCLUSION: The two main significance of this study involves predicting future management issues based on the comparison of the current issues with the 1999 issues and recommendingmanagement strategies based on the classification of issues by importance and persistence.

The authors studied the lung injury induced by endotoxemia and the effects of proteolytic agent on the lung changed by endotoxemia. Sprague-Dawley rats were intraperitoneally administrated with a single dose of endotoxin (4 mg/kg, E. coli 025 : B6 lipopolysaccharide) or with endotoxin and gabexate mesilate (200 mg/kg), a proteolytic agent, concomitantly. Rats of each group were scarificed at 9, 18, and 27 hours after injection. Light and electron microscopic examination were done. The results obtained were summarized as follows: Light microscopic exmination revealed congested capillaries and neutrophilic infiltration in both groups. Electron microscopic findings were interstitial and alveolar neutrophilic infiltration, endothelial swelling with increased pinocytotic vesicles and cytoplasmic process formation, and interstitial edema. Decrease of osmiophilic bodies in the type II pneumocytes had appeared at 9 hours after endotoxin injection. These changes were increased in severity at 18 hours and 27 hours after endotoxin injection. In the group of concomitant treatment of gabexate mesilated and endotoxin, there was no edema at 9 hours after injection. After 18 hours welling of endothelial cell and interstitial edema had appeared. However, the severity of the edema was markedly decreased. Type II pneumocytes showed well preserved osmiophilic bodies. According to these results, it is considered that administration of gabexate mesilate can significantly redeced the lung injury induced by endotoxemia.

BACKGROUND: Many trials have been conducted on the prevention of pain induced by intravenous rocuronium. The aim of this study was to assess the effectiveness of lidocaine preinjection compared with rocuronium premixed with lidocaine in minimizing pain on injection. METHODS: Seventy five patients, ASA physical status I or II, were randomly allocated to one of three groups. In the control group (n = 25), patients received saline 3 ml, followed 20 slater by rocuronium (0.6 mg/kg) only. In the lidocaine premixture group (PM, n = 25), normal saline 3 ml and rocuronium(0.6 mg/kg) premixed with lidocaine 30 mg were given intravenously, and in the lidocaine preinjection group (PI, n = 25), lidocaine 30 mg was administered before injection of rocuronium (0.6 mg/kg). Pain was assessed verbally as none, mild, moderate, and severe by the same observer. RESULTS: There was a significant reduction in the incidence and severity of pain in the PI group. Only 6 patients (24%) in the PI group experienced pain as compared to 16 patients (64%) in the PM group and 22 patients (88%) in the control group. CONCLUSIONS: Lidocaine 30 mg given before the administration of rocuronium significantly reduced the incidence and severity of rocuronium induced pain. But, lidocaine rocuronium premixtures did not significantly reduce the incidence of pain.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.

BACKGROUND: IGF-I is an important mitogen in many types of malignancies. Tumors also express many IGF binding proteins, which modulate IGF action. The purpose of this study was to evaluaste the effect of IGF-I and IGFBP on cell proliferation in mouse lung cancer cells (3LL). METHODS: The cellular proliferation of 3LL with the treatment of growth factors was evaluated using MTT assay. Western ligand blot was performed in order to determine whether 3LL cells secrete IGFBPs and we evaluated the effect of IGFBP on cellular proliferation. RESULTS: The treatment of 3LL cells with IGF-I increased cellular proliferation in a serum free media. Western ligand blot of conditioned medium of 3LL with 125I-IGF-I demonstrated one single major band with an estimated molecular mass of 24 kDa. This band was identified as IGFBP-4 with immunoblot analysis using antisera. The addition of anti-IGFBP-4 antibody to abrogate the effect of IGFBP-4 resulted in increased cellular prolife ration suggesting that IGFBP-4 inhibits cell growth. CONCLUSION: IGF-I increases cellular proliferation, however the secreted IGFBP- 4 has an ingibitory function on cell growth in 3LL. These findings suggest that IGF-I and IGFBP are involved in the cell proliferation.
