Endoscopic ultrasonography (EUS)-a combination of endoscopy a.nd ultrasonography was one of the most useful tools for diagnosis of digestive system diseases. This technique was known to be very effective in the assessment of depth of invasion in gastric cancer and in pancreatico-biliary diseases. We performed EUS in 589 patients with upper gastrointestinal and pancreatico-biliary tract lesion prior to surgery for past 22 months and examined the diagnostic accuracy of EUS, respectively. The results were compared to surgical histology in esophagus and stomach cancer,to concordance witb endoscopic retrograde cholangiopancreatography(ERCP) results for pancreaticobiliary diseases. 1) In 589 patients diagnosed with EUS, the mean age of the patients was 55.9 years with a male to female ratio of 1.7: 1. 2) Patients were divided into three groups; post-upper gastrointestinal endoscopy, post ERCP and undiagnosed with other diagnostic tools. 3) Among post-upper gastrointestinal endoscopy, 64 cases were operated due to esophageal and gastric cancer and then compared to surgical histology. After compared, EUS accuracy on depth of invasion was 78.1% and sensitivity and specificity on lymph node metastasis in gastric cancer were 76.9% and 74.3%, respectively. 4) In post-ERCP cases, EUS results were compared to ERCP results and then concordance rate was 95.4%. 5) In undiagnosed cases, EUS was performed and results were reported.

Endoscopic Variceal Ligation(EVL) was developed as an alternative to endoscopic injection sclerotherapy(EIS) for decreasing of complication rate. This new technique involves placement of small elastic O-rings around the variceal channels in the distal esophagus. To evaluate the efficacy of EVL for treatment of the acute bleeding esophagea1 varices and the efficacy of prophylactic EVL, we compared EVL in 88 patients who had recently bled from esophageal varices(Group 1) and prophylactic EVL in 45 patients with large size(Grade 2 or 3 or 4) and red color sign on endoscopic finding who had not previously had upper gastrointestinal bleeding(Group 2). Also, we compared prophylactic EVL group(Group 2) and control group(Group 3) who did not performed EVL. At the time of treatment 28.4%(25/88) of patients had active bleeding. They were all treated acutely with EVL and repeated treatment for the long-term goal of variceal eradication. Initial hemostatic efficacy of EVL for acute bleeding varices was 92%(23/25). Varices were eradicated or reduced to Grade 1 in 68%(17/2S). Early mortality rate within 2 weeks was 8%(2/25). Among patients who had eradicated or reduced to Grade 1 varices by repeated EVL sessions, over a mean follow-up of 11 months there was no difference between Group 1 and Group 2 in recurrent rate(49.1%(27/63) vs. 46.8% (15/32)), rebleeding rate(10.9'Yo (6/55) vs. 9.3% (3/32)), rebleeding interval(average 75 days vs, 83.6 days). There was significant difference between prophylactic EVL group and con- trol group in bleeding rate(9.3%(3/~32) vs. 43.7%(14/32))~(p<0.05). Three patients(6.6%) died in prophylactic EVL group, two from ligation site bleeding of esophageal varix, one from hepatic failure. In conclsion, EVL is an effective method for treatment of acute bleeding esophageal varices with repeated sessions. Although prophylactic EVL can be used to prevent bleeding by eradication with lower initial morbidity are necessary because of EVL-related complications.

BACKGROUND: One of the difficulties we have in the management of anesthesia for the optimal liver transplantation is involved in coagulopathy. The purpose of this paper is to observe and investigate the variation of the heparin effects occurred before and after the fulfillment of reperfusion done in terms of native thromboelastogram (nTEG) or heparinase-guided Thromboelastogram (hgTEG). METHODS: In 134 patients who had a living related liver transplantation, by grouping them into four according to the presence or the absence of heparin effects, we are to observethe effects on the quantity of transfusion which each group shows and clinical variables like CTP score, UNOS classification, PT, and preoperative platelet count. RESULTS: It is found that 54 out of 134 patients (40.3%) had heparin effects before the reperfusion, while 101 (75.4%) had the effects after the reperfusion to the grafted liver. It is showed that there was no significant difference in a comparison between groups involved with packed red blood cell transfused, fresh frozen plasma, platelet concentrates, fluid by RIS. In the comparison between groups involved in clinical factors, it is disclosed that although there was no significant difference in four factors, that is, CTP score, UNOS classification, PT, and preoperative platelet count. CONCLUSIONS: We can confirm that the occurrence of heparin effect after reperfusion is remarkably increasing compared to that of heparin effect before reperfusion. Also, it can be reported that heparin effects can occur frequently during liver transplantation, but they have no direct relation to transfusion.

Objectives: The purpose of this study was to develop a non-suicidal self-injury (NSSI) prevention program for adolescents and confirm its effectiveness in primary prevention by applying dialectical behavior therapy skills training (DBT-ST). Methods: From September to December 2021, 217 first-year students in three middle schools in the Chungcheong Province were tested for changes from before and after the program using the Responses to Depressed Mood Questionnaire and Difficulties in Emotion Regulation Scale-16 using paired t-tests. McNemar’s test was conducted to confirm the changes in the perception and attitude scale of NSSI for each question. Results: A comparison of the changes from before and after the program revealed that the response to depressed mood (t=7.93, p<0.001), ruminant response (t=5.18, p<0.001), and distractive response (t=6.07, p<0.001) which are subfactors of the response to depressive moods, were significantly affected. There was a significant decrease in the difficulty in performing goaloriented behavior (t=3.34, p=0.01) and lack of emotional clarity (t=2.52, p=0.012), which are subfactors of emotional regulation difficulties. Also, in the comparison of the perception and attitude towards NSSI, statistically significant changes were confirmed in 7 out of a total of 9 questions (p<0.001). Conclusion It was confirmed that this program developed by applying DBT-ST was effective in the primary prevention of NSSI for adolescents.

A 32-year-old man is being presented with a 1-week history of erythematous annular flat plaque with scales on his scalp. He displays only a solitary skin lesion on his scalp without any presence or other histories for other skin lesions or constitutional symptoms. It is difficult to consider the possibilities of syphilis based on such clinical findings. A diagnosis of syphilid is being made on the basis of clinical, serological and histological findings. Herein, we report an interesting case of secondary syphilis which is presented as a solitary annular plaque on the scalp.

PURPOSE: MMP-2, 72 kDa-type IV collagenase, plays a major role in the migration and growth of tumor cells, a process that requires the disintegration of basement membrane. Activation of MMP-2 is correlated with the invasiveness of various tumors. The aim of this study was to determine the sequence-specific phosphorothioated oligodeoxynucleotides (ODNs) inhibiting the translation of MMP-2 mRNA and the subsequent invasiveness of tumor cells. MATERIALS AND METHODS: Eight types of antisense ODNs were designed and each (8micro gram/ml) were transfected into HT1080 cells. The effects of these antisense ODNs on MMP expression were examined by gelatin zymography, Western blot, Northern blot and matrigel assay. RESULTS: Antisense-5 (+904~923), antisense-6 (+1274~+1293) and antisense-7 (+1646~+1665) reduced the MMP-2 activity of the culture supernatant in HT1080 fibrosarcoma cells. Treatment with antisense-6 showed inhibition of MMP-2 mRNA and protein, and in vitro invasion in a dose-dependent manner. CONCLUSION: Antisense-6 might be one of the therapeutic candidates for tumor invasion and metastasis.

Gastric cancer is not only one of the most common cancers in the world but also one of the most important malignant tumors in terms of incidence in Korea. In spite of it's clinical significance, the mechanism of malignant transformation in the stomach has not yet been well characterized. Recent studies disclosed enormous data suggesting that the p53 protein and the c-erbB-2 proto-oncogene have a critical role in the tumorogenesis of gastric cancer. More recently, the expression of the p53 protein has been associated with increased proliferative activity, but serves as a poor prognostic indicator in the case of patients for whom aggressive adjuvant therapy is required. Amplification of the c-erbB-2 oncogene has also been reported in gastric cancer. In the case of breast cancer, it has been demonstrated that no close correlation exists between the c-erbB-2 expression and the prognosis. However, no reports describe the relation between c-erbB-2 expression, p53 expression, PCNA expression and the prognosis for patients with gastric cancer. So this study was done to evaluate the expression of the p53 and c-erbB-2 and to assess the prognostic value in patients eith gastric cancer. The results are as follows: 1) The overall expression rates for p53 and c-erbB-2 were 38% and 20%, respectively. 2) There was no close relation between the expression rate of p53 and the tumor size, the Borrmann type, the nodal involvement, distant metastasis, Ming's classification, or Lauren's classification. The expression rate of p53 was closely related the tumor stage. 3) The expression rate of p53 in tumors which expressed PCNA was higher than that in tumors which did not express PCNA (p<0.05). 4) The expression rate of c-erbB-2 in large tumors(>5 cm) was higher than that in small tumors(<5 cm)(p<0.05). 5) The overall cumulative 5-year survival rate in the positive expression group for p53 was lower than that in the negative group, but the difference was not statistically significant(p>0.05). 6) The overall cumulative 5-year survival rate in the positive expression group for c-erbB-2 was lower than that in the negative group and the difference was statistically significant(p<0.05). In conclusion, it is suggested that p53 expression can not used as a prognostic factor for gastric cancer, but c-erbB-2 may be such a prognostic factor.
