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%).

Neuroblastoma, ganglioneuroblastoma and ganglioneuroma are derived from primordial neural crest cells and can be conceptualized as three different maturational manifestations of a common neoplasm. To assess the validity of immunohistochemistry and DNA Ploidy in the diagnosis of neuroblastic tumor in terms of prognostication, histologic and immunohistochemical evaluation with NB-84, neuron specific enolase(NSE) and S-100 protein and flow Cytometric DNA analysis were done on 21 neuroblastomas and 19 ganglioneuromas. Thirteen of 21 neuroblastomas were undifferentiated and 8 differentiating in type. Eleven of the 19 ganglioneuromas were mature in type and 8 had immature foci. Eighty one percent of neuroblastomas were positive for NB-84, 100% for NSE and 67% for S-100 protein, respectively. All ganglioneuromas were positive for NSE and S-100 protein, in contrast, only immature foci in ganglioneuroma were positive for NB-84. B-84 reacted positively with undifferentiated and differentiating neuroblasts including neuropil but not with mature ganglion cells. In contrast, NSE reacted positively with all components of neuroblastic tumor and S-100 protein mainly with cells of Schwannian differentiation. Three of eight(37.5%) differentiating neuroblastomas were strongly positive for NB-84 in contrast with seven of thirteen(53.8%) undifferentiated tumors, reflecting that undifferentiated cells tended to be positive for NB-84 in neuroblastoma. Twenty two percent of neuroblastoma showed diploidy and 78% aneuploidy including 11% of near-diploidy. Seven of eight(87.5%) differentiating neuroblastomas in contrast with seven of ten(70%) undifferentiated tumors showed aneuploidy. By contrast, 53% of ganglioneuroma showed diploidy and 47% aneuploidy with DNA index ranged from 1.12 to 1.19. Three of nine(33.3%) mature ganglioneuromas in contrast with five of eight(62.5%) ganglioneuromas with immature foci showed aneupolidy. Differentiating neuroblastoma tended to be aneuploid and ganglioneuroma with immature foci tended to be near-diploid. In conclusion, immunohistochemistry for NB-84, NSE and S-100 protein is useful for confirming neuronal, both neuronal and Schwannian, and Schwannian differentiation, respectively. Immunohistochemistry together with flow cytometric DNA analysis would be helpful to confirm the immature foci in ganglioneuroma.

Biliary cystadenoma of the liver is a rare multilocular cystic neoplasm of biliary origin. it occurs most often in middle aged women and rarely in children. Histogenesis of this tumor is uncertain. It may be developmental in origin arising from aberrant hamartomatous bile ducts or ectopic rests of embryonic biliary cystadenoma of the liver discovered at 8 month of intrauterine fetal life. This case supports its congenital theory.

The frequency of HLA-B27 antigen in 24 patients with psoriasis vulgaris and 11 patients with psoriatic arthritis were examined using the standard micro-lympho- cytotoxicity technique. There was a high frequency of HLA-B27 in psoriatic spondylitis with or without peripheral arthritis (83.3%) compared to controls (4.7%) and the relative risk of HLA-B27 for developing psoriatic spondylitis was 82.5% which indicates a strong association between HLA-B27 and psoriatic spondylitis in Korean populations. However, there was no stastical significance observed in the groups of patients with peripheral arthritis alone or psoriasis vulgaris in regard to the frequency of HLA-B27.

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.

The study was performed to measure and compare the peripheral blood T cell and T subsets in normal controls and psoriatic patients. Thirty-two normal controls and fift:en psoriatic patients were subjected to the study and the percentages and the rati vs of peripheral blood T cell and T subsets were measured. The results were as follows: 1. Mean percentages of peripheral blood lymphocytes reactive with OKT3 monoclonal antibody in psoriatic patients were 72. 8+-8. 2%, They decreased significantl) as compared with these in control group(76, 6- i-4. 7%). Mc an percentages of peripheral blood lymphocytes reactive with OKT4 monoclonal antibody in psoriatic patients were 47. 3+6, 7p;. They increased as compared with these in control group(46. 5+-3. 9p;), but the increase was insignificant. 3. Mean percentages of peripheral blood lymphocytes reactive with OKT8 monoclonal antibody in psoriatic patients were 27. 2+5. 5g, They decreased significantly as compared with these in control group(30, 6- l-4. 3%) 4. Mean ratios of lymphocytes reactive with OKT4 monoclonal antibody to these reactive with OKT8 monoclonal antibody in psoriatic patients were 1.8+- 0. 48 They increased significantly as compared with these in control group(1. 6+ 0.34).

Primary cancer af the duodenum is rare. An extensive experience with fiberoptic eaophag-ogastro-duodenoscopy in our institution has indicated that duodenal cancer may be more frequent thsn suspeeted and readily diagnesed by this modality, With this in mied, clinical, pathological, diagnostic and therapeetie aspects of the 26 patients with primary duodenal cancer which had been endoscopically diugnosed were reviewed. The results obtained were as follows: 1) Ages ranged from 16 to 75, with the mean of 55.2 years. Seventeen patients were men and nine patients women being l. 9:1 of male-female ratio. 2) Hndoscoyic findings were 46. 1 percent ulcerative anld 34. 8 per cent ulcerative-infiltrative, 3) The diatribution within the duodenum was 50 per cent suprapapillary, 42. 4 per cent peri- papillary aecl 7. 6 per cent infrapapillary. 4) The twenty-three patients had adenocarcinoma, two patients leiomyosarcoma and 1 patient lymphoma. 5) Twenty patients were confirmed by duodenoseopic biipsies and six patients by operations. 6) The mast common presenting mmyliiints were abdominal pain, chronic blood lais leading anemia, jaundice, anorexia, indigestion, weight lass and palpable abdominal mass. 7) Of the 26 patients, eight patients underwent attempted curative resection, six patients underwent palliative bypasa procedures or exploratory laparotomy.

Vertebral pedicle screws have been widely used for secure posterior spinal fixation. When postoperative CT scan films were made, the blurring of pedicle screws were observed and we could not figure nut the exact diameter of screw and canal encroachment. There is no information in the difference hetween actual diameter and measured diameter of pedcile screws in CT yet. In this study, we try to find out partial voiume averaging artifact of pedicle screws made of stainless steel and titanium. Partial volume averaging artifact occurs when the shape of an object changes within the thickness of the CT slice or when a relatively small object is only partially included within the slice. Four pig cadaveric spinal column including 6 vertebrae each were prepared and CT scans were performed after insertion of C-D screws(stainless steel) to the left and TSRH screws(titanium) to the right pedicle. Another CT scans were performed after insertion of C-D screws to the right and TSRH screws to the left pedicle. The third CT scans were made after removal of all the pedicle screws. Actual C-D screw diameter was 6mm and CT scanned diameter was 8. I 6+/-0.66mm. Actual TSRH diameter was 6.5 mm and CT scanned diameter was 6.59+/-0.34mm. In conclusion, stainless steel has more partial volume averaging artifact than titanium. Safety margin of pedicle screw made of stainless steel is about 2mm and that of titanium is about 1 mm.
