PURPOSE: To evaluate the efficacy of the arterial phase of dynamic spiral CT in the detection of pancreatic adenocarcinoma compared with the late phase. MATERIALS AND METHODS: Two phase spiral CT images of seventeen patients with pathologically proven pancreatic ductal adenocarcinomas were compared retrospectively. CT scans were performed with 5mm collimation at 1:1 pitch table speed. Images of arterial and late phases were obtained at 35 seconds and 180 seconds after initiation of administration of 100mL of contrast material(3mL/sec), respectively. Images of the arterial phase were compared with those of the late phase. RESULTS: Images of the arterial phase showed sufficient contrast between the tumor and adjacent pancreatic parenchyma in 12 cases, insufficient in four cases, and no significant contrast in one case. Images of the late phase showed sufficient contrast in five cases, insufficient in five cases, and no significant contrast in seven cases. Images of the arterial phase was superior to that of the late phase in 12 patients(70.6%). In six of the 12 patients, only the images of the arterial phase showed contrast between the tumor and the adjacent parenchyma. The images of late phase showed only one case of three metastasis detected on the images of the arterial phase. CONCLUSION: The arterial phase of spiral CT is superior to the late phase that is comparable with conventional CT in the detection of pancreatic adenocarcinoma.

This study describes an evaluation of the sonographic, cholangiographic, pathological, and immunological findings, and the protective effect shown by rats reinfected with Clonorchis sinensis. Eight experimental rat groups were, namely, a normal control, a primary infection control, a reinfection I (reinfection 7 week after treatment following 3-week infection), a reinfection II (reinfection 2 week after treatment following 8-week infection), a reinfection III (exploration of the intrahepatic bile ducts 1 week after reinfection 4 week after treatment following 4-week infection), a superinfection, a secondary infection control, and an infection following immunization group. Sonographic and cholangiographic findings showed moderate or marked dilatation of the bile duct confluence in the primary infection control, reinfection II, and secondary infection control groups. Juvenile worms survived in the intrahepatic bile ducts 1 week after reinfection following treatment in the reinfection III group. It was concluded that reinfecting juvenile worms found during the first week following reinfection failed to survive or grow further. Anatomical, pathophysiological, or immunological changes may induce protection from reinfection in rats.

This study was carried out to find out specific proteins from different organs of Clonorchis sinensis. Crude extract, organ-specific and excretory-secretory (ES) proteins were analyzed by immunoblot with infected human sera. The bands of 7- and 17-kDa were main component of intestinal fluid and ES protein and commonly found in all organspecific proteins. The 17-kDa protein was observed from ES antigen, intestinal fluid, eggs and sperms, 26- and 28- kDa proteins were from the uterus, vitellaria, and ovary, and 34-, 37-, 43- and 50-kDa proteins were mainly from the testis and sperms. Serum of mice immunized with sperms reacted to the 50-kDa protein by immunoblotting and immunohistochemical staining showed a positive reaction at the seminal receptacle and seminiferous tubule. The present results show that the 7-kDa protein is a common antigen of every part or organ of C. sinensis, but different organs express their specific antigenic protein bands.

The authors performed percutaneous antegrade pyelography guided by ultrasound on 33 patients, from J une 1982 to October 1984, at the department of radiology, Busan National University Hospital. The results obtained were as follows: 1. Of the 31 cases,17 cases (5 1.5%) were female and 16 cases (48.5 %)were male,and age distribution was nearly even, but most prevalent age group was third decade. 2. Comparing intravenous pyelographic findings with ultrasonographic findings, pyelographically non. visualized kidney 15 cases (45 .5%) were hydronephrosis 12 cases, multiple cysts 2 cases, and intrarenal cystic mass 1 case, ultrasonographically. Pyelographically hydronephrosis 9 cases (27.3%) were all hydronephrosis, ultrasonographically. Intrarenal mass 5 cases (15.2%) were all intrarenal cystic mass, NVK with air in kidney 1 case (3.0%) was air in perirenal space, partial NVK 1 case (3.0%) was per. irenal fluid , suprarenal mass 1 case (3 .0%) was suprarenal intrarenal and huge perirenal cystic masses, ultraso nograp h ically. 3. On technical reliability of antegrade pyelography under ultrasound gUide, 31 cases (93 .9%) could be done fluid aspiration and visualization, and 2 cases (6.1 %) could be only done fluid aspiration but failed visualization . 31 successful cases were visualization of collecting systems 23 cases, visualization of cyst 6 cases, i!nd visualization of perirenal space 2 cases. 2 partial successful cases were perirenal injection 1 case and parenchymal injection 1 case. 4. On fluid aspiration, 22 cases (66.7%) were clear, but 11 cases (33.3%) were not clear, which were pus 7 cases, turbid urine 2 cases, bloody urine 1 case, and bloody pus and air 1 case. 5. Comparing ultrasonographic findings with antegrade pyelographic findings, ultrasonographically hydronephrosis 21 cases revealed obstruction in 16 cases, antegrade pyelographically, which were consisted of ureteral stricture 14 cases, ureteral stone 1 case, and ureteral mass 1 case, non-obstruction in 4 cases, which were consisted of pyonephrosis 2 cases, posterior urethral valve 1 case, and megaureter 1 case, and other 1 case was visualization failure. Ultrasonographically intrarenal cystic mass 6 cases were simple renal cyst 4 cases, and infected renal cyst 2 cases, antegrade pyelographically. Multiple cysts 2 cases were lobulated huge renal cyst 1 case, and visualization failure 1 case, which was multi.cystic kidney. Air in perirenal space 1 case was emphysematous pyelone. phritis, suprarenal cystic mass 1 case was complete duplication with ectopic ureteral orifice, perirenal fluid 1 case due to kidney fracture was perirenal fluid , and intrarenal and perirenal cystic mass was per irenal abscess, antegrade pyelographically. 6. On ana lysis of anteg rade pyelography result as next diagnostic step of ultrasound, 31 successful cases were 27 conclusive diagnostic cases (87.1%), and 4 heplful diagnostic cases (12.9%) with percutaneous antegrade pyelography guided by ultrasound . 7. Antegrade pyelography provides significant diagnostic information on the nature of the obstructive lesion and can be performed as an adjunct to retrograde study or as an alterative to a pyelogram. 8. Ultrasonographic examination could be performed easiJy in diagnosis of renal and perirenal diseases as non.invasive method without risk of radiation hazard , and was not influenced by renal function. 9. Ultrasound is considered a most advantageous aid to the performance of antegrade pyelography and has yie lded valuab le diagnostic information in patients with obstructive hydronephrosis.

Since the first attemt of internal fixation not much more than a century ago, implants have come to play an important role in orthopaedic surgery. Yet little has been reported about complications which may result from implant surgery. During the period of May 1980 to April 1984, 32 cases of fixation failures were treated in the Department of Orthopaedic Surgery, Hallym College, Kang Nam Sacred Heart Hospital and results were obtained as follows: 1. The most common area involved femoral shaft, but the highest rate was distal femur. 2. The most common period of failure was between 2 to 4 months postoperatively. 3. The leading cause of failure was remaining defects at fracture site. 4. The authors recommend accurate reduction of fracture and bone graft, if necessary, adequate immobilization postoperatively and co-coperation of patient to avoid failure of implant.

The 8 kDa antigenic protein of Clonorchis sinensis was partially purified by ammonium sulfate precipitation and subsequently by a column chromatographic steps. The purified protein was separated into 7 and 8 kDa protein bands through SDS-tricine gel electrophoresis, while the protein was found to migrate to a 8 kDa band in 7.5-15% SDS-PAGE. The molecular weight of the antigen was estimated to be 110 kDa by Superose 6 HR 10/30 gel filtration. The purified antigen strongly reacted with the human sera of clonorchiasis. The hyperimmune sera of BALB/c mice immunized against the 8 kDa protein were reacted with both the crude extract and the excretory-secretory product of adult worms, but not with the metacercarial extract. Immunohistochemical staining demonstrated that the protein was distributed to the tegument and subtegumental cells and also to the seminal receptacle. The present findings suggest that the 8 kDa protein is a partition of the multicomplex protein originating from various organs of adult C. sinensis, and that it is composed of several 7 and 8 kDa proteins.

An 84-year-old woman had an ovoid shallow ulcer with an elevated, indurated, pigmented border on the left cheek. Histological examination revealed a moderately differentiated squamous cell carcinoma and a solar keratosis with abundant melanocytes and melanin pigment. Ultrastructurally, the keratinocytes contained numerous melanosomes in their cytoplasms and the melanocytes in the squamous cell carcinoma and the solar keratosis had mature melanosomes.
