Peri-vater divertieula may interfere with the normal flow of biliary and pancreatic secretion, thus leading to pancreatobiliary diseasa and the very presence of juxtapapillary diverticulum makes cannulation technically difficult and contributes to the low success rate. In this present series, the relationship between duodenal diverticula and age, sex, and biliary-pancreatic pathology was stud.ied in 1400 patients examined with ERCP. The results are as follows. 1) Duodenal diverticula was demonstrated in 73 of 1400 patients(5, 2%). 2) The incidence of duodenal divertieular increased with age and they were more frequent in men. 3) The cannulation of one or both duct system was suecessful in 69 of the 73 patients, the success rate was 94. 5%. 4) The biliary pathology was found in 41 of the 73 patients and the pancreatic pathology in 6 of the 73 patients. The rnost common finding was biliary calculi which were demonstrated in 35 patients(47. 9%).

Choledochal cyst of the common bile duct is usually considered to be large cystic dilatation that extends from the wall of the common bile duct. Choledochal cyst is a very rare cond.ition in adult, These cysts are commonly distinctive in childran under the age of ten. Even in this age group they are considered rare. The classicajl triad of a choledochal cyst inclule pain, jaundice and a palpable right upper quadrant mass. This triad was found in only 21~63% and the most common finding is jaundice. Diagnoais of choledochal cyst usually is made during laparotomy, In nonjaundiced patients, oral cholangiogram and/or intravenous cholangiogram may yield the diagnosis. In jaundiced patiente where the diagnosis may be more difficult to make, one may consider doing ERCP and/or percutaneous transhepatic cholangiogram. The percutaneous transhepatic cholangiogram seems to be very helpful in diagnosing jaundiced patients. It is being used more and more in recent years but this method is not without complication. With advent of ERCP, visualization of the biliary tree has become a simple procedure when performed by expert endoscopists. To our knowlege, no previous case of choledochal cyst diagnosed by ERCP has been reported. yet in our country This paper reports 4 cases of choledochal cyst diagnosed by ERCP.

Candida Albicans is a saprophytic organism under normal circumstances and a limited pathogen when presents in large numbers. The common site of infection are the mouth, skin, vagina and respiratory tract. It is a common inhabitant of the G-I tract, where it does not usually cause symptoms. With impared defense mechanism or long-term antibiotic therapy, however it can became a significant pathogen. The clinical symptoms and endoscopic findings present a spectrum of changes depending on the degree of esophageal involvement. Painful awallowing and substernal chest pain are most common symptoms. Esophgeal infection is an unusual but impartant form of the diseases and can easily be confirmed by esophagoscopy. Recently we have experienced 4 cases of esophageal moniliasis confirmed by esophagoscopy and tissue biopay.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most useful diagnostic tool in biliary and pancreatic disease. However, ERCP cannot be performed successfully in all patients. Cannulation failure is the most common cause of failure of ERCP. Mechanical pathologies, such as peri-Vater diverticulum, cancer of the papilla of Vater, and impacted stone were the common causes of cannulation failure. We experienced two cases of carcinoma of the papilla of Vater in whom cholangiography and insertion of the nasobiliary tube were performed througth an artificial choledoehoduodenal fistula made by a needle type diathermy knife, beacuse cannulation to the duct was failed due to the tumor.

This study was undertaken to investigate the efficacy of 5% PABA cream using mouse ear swelling reaction(ESR). Mice were exposed to 100mJ/cm of UVB, five times a week for four weeks, on the both ventral aspect of the ear, with application of 5% PABA cream on the right ear. The results were as follows : 1. The intensity of ear swelling reaction of 5% PABA protected group was reduced greater than unproteeted group after the first 3 days of UUR. 2. The intensity of ear swelling reached at peak after 1 week of the ultraviolet radiation. Thereafter it has decreased gradually the following 4 weeks. The difference of ear swelling between the two groups was the greatest after 1 week, and the sunscreening efficacy of 5% PABA cream has remained persisted for 4 weeks. 3. The number of mice which have shown severe inflarnmatory response after ultravioiet radiation was more in unprotected group than that in 5% PABA protected group. 4. Determination of mouse ESR is considered a good method for the evaluation of longterm efficacy of sunscreen preparation.

Confluent and reticulated papillomatosis (Gougerot and Carteaud) is a rare but clinically distinct dermatosis of which the etiology is unknown. We report 2 cases. One case is a 16-year-old boy who had a hyperpigmented reticulated eruption on the trunk and both arms and the other case is a 33-year-old man who had a similar eruption on the chest and back. The former, with previous treatment with oral and topical antifungal agent in another clinic didn't show any improvement and the latter case, with initial treatment of itraconazole did not improve his skin lesion. The rashes of two patients virtually disappeared with administration of minocycline. These observations indicate that the role of microorganisms sensitive to minocycline or anti- proliferative effect of minocycline could be presumed.

Postcholecystectomy syndrome is the persistence or recurrence of symytom complex following cholecystectomy, The majority of the patients have mild symptoms. However, the cause of recurrent symptoms is often obscure and as a consequence, a plan of management is difficult to formulate. Recently ERCP has proved to be increasingly helpful in the investigation of postcholecystectomy patients. The purpose of this study was to test the effectiveness of the ERCP in the evaluation of patients with postcbiolecystectomy syndrorae. The results are as follows 1) 102 postcholecystectomy patients were studied by endoscopic retrograde cholangiopancreatography and successful cannulation with demonstration of at least one duct was achieved in 49 of 50 jaundiced patients and in 49 of 52 non-jaundiced patients. The overall success rate was 96. 1%. 2) The results of ERCP were normal in 26 patients(26.5%) and abnormal in 72 patients (73.5%), Only 3 of 50 jaundiced patients were normal, but 23 of 52 non-jaundiced patients showed no abnormal findings. 3) The most common abnormality was biliary stone in common bile duct and intrahepatic duct which were present in 51 patients(50%). Cholangitis without stone was next common finding which was in 13 patients(13%). Of the remaining patients have air biligram, 2 CBD stricture, 1 CBD aseariasis & 1 chronic pancreatitis. 4) Time lapse between onset of symptoms and cholecystectomy was variable. 31 patients were studied less than 2 years after cholecystectomy. 18 of these patients had jaundice and 13 had no jaundice. Within 2 years afte chklecystectomy, the biliary stone was most common finding which were present in 14 out of 31 patients.

STATEMENT OF PROBLEM: Implant abutment screw joints tend to loosen under clinical conditions. Abutment screw loosening results in loss of preload in function. PURPOSE: Anti-rotational inner post screw (ARIPS) systems were compared with conventional abutment screws to reduce screw loosening. Reverse torque values were evaluated. MATERIAL AND METHODS: 32 implant assemblies (Warentec, Co, Ltd, Seoul, Korea) were organized as the 30-Ncm-torque conventional groups and 30-Ncm-torque ARIPS groups in external and internal system. The specimens were tested to 10(6) cycles at a load of 200N. Preload reverse torque, postload reverse torque, and the ratio of postload reverse torque to preload reverse torque were evaluated. The data were analyzed with unpaired t-test in external and internal systems. RESULTS: In the ratio of postload reverse torque to preload reverse torque, the ARIPS groups showed significant differences than the conventional screw group in both external and internal system. CONCLUSION: Within the limitations of this study, abutment screw loosening was effectively reduced using ARIPS system.

Perutaneous Transluminal Angioplasty(PTA) is an effective initial treatment modality in renovascularhypertension. For determination of PTA effect, the pulse pressure recording of renal artery is not simple ascompared with in femoral artery stenosis. We tried to evaluate the PTA effect of renal artery stenosis withtracing the pressure of distal renal artery. We used the cardiac catheterization apparatus(VR-12 Honeywell) as apressure monitor in two cases of focal renal arterial stenosis. The renal artery pressure was doubled after firstattempt of ballooning, and the pressure elevated up to 94% and 79% of aorta pressure in two cases, respectively,after third attempt. We believe that renal artery pressure monitoring is a good method of determination of PTAeffect in renovascular hypertension.
