Kaposi's sarcoma is a rare tumor comprising 0.1 per cent of all malignancies worldwide. There is, however, an increased ineidence following renal transplantation, immunosupression and in the acquried immunodeficency syndrome(AIDS) Kaposi's sarcoma has been shown to involve every organ of the body except the brain. Gastrointesinal involvement is the most common extracutaneous site of involvement. Gaatrointesinal Kaposis sarcoma is preaent in approximately half of patients with cutaneous Kaposis sarcoma and the acquired immune deficiency syndrome(AIDS). Although usually asymptomatic, gastrointestinal Kaposi's sarcoma may cause pain, bleeding, diarrhea, obstruction, intussusception, perforation. malabsorption, and protein-losing enteropathy. Three distinct gastroscopic appearances of Kaposi's sarcoma have been described: maculopapular, polypoid, and umbilicated nodular lesions. We report a case of Kaposis sarcoma of the stomach.

The potential of malignant melanoma to metastasize to all parts of the body is well known. Metastatic melanoma of the stomach may present with vague gastrointestinal symptoms, abdominai pain, or gastrointestinal bleeding. When gastrointestinal symptoms occur in a patient with known melanoma, gastric metastases should be considered. Melanoma metastatic to the stomach develops multiple small ulcerating masses. These sharply delineated submucosal lesions have been described as having a "bull's eye" or "target" configuration. Barium X-ray study, endoscopy, cytology study, and biopsy may yield the diagnosis. The prognosis is poor. We report a case of metastatic melanoma of the stomach with the review of the literature.

The purpose of this study is to compare the osteogenic activity of pBMP combined with the following, freeze-dried allogeneic bone, surface demineralized allogeneic bone, and demineralized allogenic bone powder in rats. So, authors made partial purification of the pBMP. Using rat calvaria, an 8mm size in diameter boney defect was grafted using pBMP-ibm in the experimental group A as the control group, freezed dried allogeneic bone graft plus pBMP-ibm in the experimental group B, surface demineralized allogeneic bone graft plus pBMP-ibm in the experimental group C, and demineralized allogeneic bone powder plus pBMP-ibm in the experimental group D, respectively. The rats were sacrificed at the week of 1st, 2nd, 4th, 8th after implantation and examined grossly, biochemically, biomechanically, microscopically. The results were as follows 1. Ares of Implanted defect acquired osseous union at post op 4th week. 2. According to the result of hardness test, the experimental group B was most rigid than any other experimental groups at post op. 4th week. And the experimental group B, C and D were more rigid than the experimental group A at post op. 8th week. 3. As time goes on, calcium content of implanted area has increased gradually in all experimental groups except the experimental group B. 4. In the early stage of grafting, the new cartilage formation & new bone formation were more active in the experimental group B, C and D than in the experimental group A, but in the late stage of grafting, there was no significant difference in the new bone formation among the experimental groups. 5. New cartilage and new bone formation occurred as follow, first in the experimental group D, then the experimental group C, the experimental group B, the experimental group A, respectively.

Behcets syndrome is a multisystem disorder presenting with recurrent oral and genital ulcers as well as uveitis, Gastrointestinal involvement associated with ileal ulcer is rare, but its outcome may by fatal. We have recently experienced a 43-year-old man who had Behcets syndrome with ileal ulcer penetrated to 3rd portion of the duodenum. He had been updergone right hemicolectomy and ileocolostomy for ileal inflammation of unknown etiology 20 years ago. Thereafter he had had relapsing oral and genital ulcers, and abdominal pain intermittently. From 15 days ago before visiting our hospital, he had severe abdominal pain and dark blood-colored stool. The colonofiberscopic finding revealed a large, deep penetrating ulcer and multiple shallow ulcers on the ileum. Deal segmental resection, gastro-jejunostomy and jejunal patch at 3rd portion of the duodenum were performed with marked improvement.

BACKGROUND/AIMS: In HCC with low AFP. we have to use repeated imaging study to evaluate residual viable rumor or recurrence after TACE ( transarterial chemoembolization). We performed the study to know that sICAM-1 in HCC can be a tumor marker of diagnosis and has cor relation with tumor size or clinical staging. The results were compared with PIVKA- , an another tumor marker of HCC. METHODS: Previously untreat ed 39 pat ients with HCC were evaluated. Serum sICAM- 1, AFP and PIVKA-II were measured by EIA, immunoradiometric assay and EIA, respectively. Tumor size were meas ured by abdominal CT and angiogr aphy. RESULTS: Range of sICAM- 1 levels with HCC patients were 189.0 to 983.6 ng/ mL, and mean value was 668.3+- 254.4 ng/ mL. Thirty four of the 39 patients (87.2%) with HCC showed sICAM- 1 levels higher than 306.4 ng/ mL (mean of 131 healt hy controls + 2SD level). Range of PIVKA-II level with HCC patients were 25.3 to 2,779.3mAU/nL, and mean value was 1,340.1+-1,091.1mAU/mL. seven of the 39 patients(94.9%) with HCC showde PIVKA-II levels higher than 40mAU/mL. Range of AFP levels with HCC patients were 4.2 to 57,520ng/mL, and mean value was 4,215.6+-10,807.2ng/mL. 10 patients (26%) showed AFP lower than 20ng/mL, and 17 patients(44%) were AFP lower than 100ng/mL. All of the 17 patients with alphaFP lower than 100ng/mL had s ICAM-1 levels more than reference range (mean of 131 healt hy cont r ols + 2 SD level), and PIVKA-II levels also more than reference range. Positive correlation was observed between PIVKA-II level and tumor size in 18 patients without vascular invasion. Accor ding t o HCC clinical staging, 10 patients (25.6%) belonged clinical stage II. 5 pat ients (12.8%) III, 24 pat ients (61.5%) IV. Both of PIVKA-II and sICAM-1 levels of stage showed significantly higher than stage II. PIVKA-II showed more positive correlation with tumor size and clinical stage than sICAM- 1. No correlation was found between AFP and sICAM-1, and positive correlation was AFP and PIVKA-II. CONCLUSION: In HCC patients with low AFP, sICAM-1 and PIVKA-II correlated with tumor size and clinical stage. sICAM-1 and PIVKA-II may be a useful marker of diagnosis. So, we need to further study to evaluate whether sICAM- 1 and PIVKA-II can be used as a marker of disease progression or prognosis.

The double pylorus-is a fistulous communication between the gastric antrum and duodenal bulb, usually extending from the lesser curvature of the stomach to the superior aspect of the duodenal bulb, and seperated by septum or bridge of normal mucosa. Although its incidence is rare, reports concerning double pylorus are increasing with the recent development of upper gastrointestinal endoscopy and more awareness of this abnormality. We recently experienced two cases of double pylorus; an aquired one in 72-year old male who had an another opening with healing ulcer at the superior aspect of the original pyloric channel, central erosion with clubbing and fusion of mucosal folds at the greater curvature of the lower body and a 3 x 4 cm sized ulcer at the lesser curvature of the lower body, and the other congenital one in 53-year old male who had an another opening at the superior aspect of the original pyloric channel with histologically intact muscularis mucosa in the pyloric septum with no evidence of chronic peptic ulcer scarring. We report here two cases of double pylorus, one-acquired, and the other-congenital, with a review of the literature.

OBJECTIVES: We assessed the public acceptance of a health information exchange (HIE) and examined factors that influenced the acceptance and associations among constructs of the Technology Acceptance Model (TAM). METHODS: We collected data from a survey of 1,000 individuals in Korea, which was administered through a structured questionnaire. We assessed the validity and reliability of the survey instrument with exploratory factor analysis and Cronbach's alpha coefficients. We computed descriptive statistics to assess the acceptance and performed regression analyses with a structural equation model to estimate the magnitude and significance of influences among constructs of TAM. RESULTS: Eighty-seven percent of the respondents were willing to use the technology, and the average level of agreement with the need for the technology was 4.16 on a 5-point Likert scale. The perception of ease of use of the technology significantly influenced perceptions of usefulness and attitudes about the need for HIE. Perceptions of usefulness influenced attitude and behavioral intention to use HIE, and attitude influenced intention. Age showed a wide range of influences throughout the model, and experience with offline-based information exchange and health status also showed noteworthy influences. CONCLUSIONS: The public acceptance of HIE was high, and influences posited by TAM were mostly confirmed by the study results. The study findings indicated a need for an education and communication strategy tailored by population age, health status, and prior experience with offline-based exchange to gain public buy-in for a successful introduction of the technology.
