N/A Histopahological and histochemical studies were done in the bile ducts of clonorchis sinensis (CS) infested rabbits. The duration of clonorchis sinensis infestation in the rabbits was between 12 and 17 months and the number of clonorchis sinensis metacercariae which were infested orally was 50-150 per rabbit. Hematoxylin-eosin and avidin-biotin peroxidase complex lectin staining methods were used for this study. Pathological changes of the bile ducts of CS-infested rabbits were papillarv and adenomatous hyperplasia, goblet cells and mucus cells rnetaplasia, ductal wall fibrosis and infitra tion of eosinophils in the ductal wall. These pathological changes were noted both in peripheral and central protion of bile duct. The pathological changes of hyperplasia and metaplasia of ductal epithelium were more marked in the deep gland than surface one, and dysplasia of the epithelium was more marked in the suface gland than deep one. In clonorchis sinensis infested rabbits, the lectins of Soybean agglutinin (SBA), Dolichos biflours agglutinin (DBA) and Ulex europaeus agglutinin (UEA I) were labelled predominant]y in the luminal suface, supranuclear protion of epithelium, goblet cells, hyperplastic cells and metaplastic cells of deep gland . SBA and DBA were labelled weakly to intermediate and UEA I was labelled weakl y to strong, but Peanut agglutnin (PNA) was ]abelled very weakly to those sites in CS-infested rabbits. In non CS infested rabbits, lectins of SBA, DBA, and UEA I were only weakly labelled in the luminal surface of epithelium. In this study, IJEA i which binds specifically glycoprotein of fucose was more pronounced in rabbits infested with CS and so it is postulated that increased activity of fucosyl transferase should be associated with CS infestation.

N/A Liver biopsy by Menghini technique has a relatively low sensitivity and high risk in diagnosing space occupying lesions of the liver. Moreover, any biopsy method except exploratory laparotomy has not been useful in pancreatic lesions. Recently ultrasonically guided percutaneous fine needle aspiration cytodiagnosis is widely used in evaluating space occupying lesions of the liver and deep-seated organ, such as pancrea, because of its high sensitivity, safety and simplicity. Ultrasonically guided percutaneous fine needle aspiration cytodiagnosis was carried out to evaluating its diagnostic performance in 20 patients with space occupying lesions of the liver and in 3 patients with pancreatic lesions who were admitted to the Pusan National University Hospital from Oct. 1985 to Jan. 1986. The results were as follows: 1) Clinically diagnosis before ultrasonically guided percutaneous fine needle aspiration cytodiagnosis were primary hepatoma in 16 patients, liver abscess in 2 patients, hepatic cyst in 2 pateints, pancreatic cancer in 2 patients. 2) The cytodiagnosis in space occupying lesions of liver were as follows: The 14 patients of the 16 patients with clinically primary hepatoma were positive. All of the 2 patients with suspected liver abscess were confirmed. And all of the 2 patients with suspected heaptic cyst were same as clinical diagnosis. 3) The cytodiagnosis of the pancreatic lesions were as follows: Of the two patients with suspected pancreatic cancer one was positive and the negative patient were confirmed pancreatic cancer by the exploratory laparotomy. One patient with clinically pancreatic cyst was revealed as pancreatic cyst by the cytodiagnosis. 4) There was no complication in performing ultrasonically guided percutaneous fine needle aspiration cytodiagnosis.

Endoscopic biilary drainage (EBD) for malignant obstructive jaundice is performed mostly with EST. But EST carries early complications such as bleeding, perforation and pancreatitis. We evaluated safety and usefulness of EBD using endoscopic papillary balloon dilation (EPBD) without endoscopic sphincterotomy (EST). Fifteen patients were treated from Sep. 1998 to Feb. 1999 in Pusan National University Hospital due to malignant obstructive jaundice. EBD was performed using EPBD. They were investigated to estimate the usefulness and early complications of EBD using EPBD. Effective drainage was achieved in 13 patients (87%). Procedure related complications developed in two patients; acute pancreatitis in two(minimal or mild, 13%), hemorrhage in three (clinically insignificant bleeding) EBD using EPBD is a safe and effective treatment method for malignant obstructive jaundice. However, prospective study is thought to be need in large patients group especially as to stent diameter and papilla size.

N/A Objectives : It is known that nutritionally depressed patients are approximately 40 to 50% among all of the hospitalized patients and these patients are more vulnerable to complications and delaying in recovery from their diseases than nutritionally normal patients . Exact nutritional assessment and support are one of important measures in treatment of the disease. Both subjective and objective methods of nutritional assessment has been applied usually for exact nutritional assessment and anthropometry has been used for objective assessment of nutritional state. Methods : Author measured of anthropometry such as weight, height, triceps skin folds, midarm muscle circumference, and midarm circumference in order to get standard values of anthropometry in 2926 healthy korean adults from five different districts in Korea. Results: The mean values of the height of Korean were 169±5.9 cm in male, and 156.3±7.9 cm in female and the mean values of 50 percentile of the height were 170 cm in male and 157 cm in female. The mean values of the body weight were 64.2±20.2 kg in male, and 54.5±7.4 kg in female and the mean values of 50 percentile of the body weight were 63 kg in male, and 54 kg in female. The mean values of TSF were 11.7±7.1 mm in male, and 18.5±7.6 mm and the mean values of 50 percentile of the TSF were 10 mm in male, and 18.0 mm in female. The mean values of the MAC were 26.7±3.3 cm in male, and 25.77±.90 cm in female and the mean values of 50 percentile of the MAC were 26.5 cm in male, and 26 cm in female. The mean values of the MAMC were 23.0±3.5 cm in male, and 19.95±3.0 cm in female and the mean values of 50 percentile of the MAMC were 23.0 cm in male, and 19.8 cm in female. Conclusion : The values of this study could be used as the korean standard values having some errors due to different study members, because it was done in large subjects who are living in five different districs in Korea.

N/A Famotidinei(Gaster R ) is new H2-receptor blocker with an amide structure at the side chain of thiazole. We have treated 40 cases of endoscopically diagnosed peptic ulcers with famotidine for evaluation of the therapeutic efficiency. Famotidine was administered 20 mg two times daily for 4 weeks and then followed up by endoscopy. Over all improvement of peptic ulcers by endoscopy noted in 77.5% of the patients. 17 out of 22 cases (77.3%) of gastric ulcers and 14 out of 18 cases (77.7%) of duodenal ulcers had been healed up in 4 weeks. Manifestations of peptic ulcer had been improved in 33 out of 40 cases (82.5%) after 4 weeks medication with famotidine. No significant clinical side effects had been noticed with 4 weeks medication. In conclusion, famotidine is effective and safe medicine for the treatment of peptic ulcer diseases.

N/A Objectives: The causes of benign esophageal stricture were postoperative, corrosive, peptic and after esophageal sclerotheraphy, etc. The patients mainly suffered from dysphagia and insufficient nutrition. Recently, balloon and bougie dilatation were introduced to these patients. This study was performed to evaluate the effectiveness and safety of both procedures in different types of strictures Methods: 32 patients who presented dysphagia enrolled from March 1996 to August 1997 who visited Pusan National University Hospital. Balloon dilatation was performed on 22 patients and bougie on 10 patients. Results: 1) The causes of stricture were postoperative (18 cases), corrosive (10 cases), hypertensive LES (2 cases), peptic (1 case) and web (1 case). 2) Overall cure rate was 59% in e dilatation and 40% in balloon dilatation 3) The cure rate of postopertive stricture was 59% which is significantly higher than that of corrosive stricture (27%), and cure rate of hypertensive LES peptic stricture and web was 100%. 4) Tje cure rate of carrosive stricture was significantly higher on bougie dilatation than balloon dilatation. 5) The cure rate of postoperative stricture was similiar between balloon and bougie dilatation 6) The length of stricture was inversly affected on cure rate of both dilatation procedures. 7) Overall complication was 5.6% and similiar between balloon and bougie dilatation. Conclusions: These results suggested that bougie dilatation was recommended on corrosive stricture and balloon dilatation on postopertive stricture
