We report two cases of ectopic epididymal ducts and efferent ductules in the testicular appendices (TAs) of adult men with normally descended testes. In both cases, a sessile TA was incidentally found at the upper pole of the right testis during the scrotal hydrocelectomy. Microscopically, a few closely arranged tubules were detected within the TA. In the first case, the tubules were lined with a pseudostratified columnar epithelium with numerous, long microvilli, and were surrounded by a smooth muscle coat. In contrast, in the second case, the tubules had a wavy luminal surface, because ciliated columnar cells alternated with groups of cuboidal cells. In both cases, strong CD10 immunoreactivity was observed in the luminal border of the lining epithelium. Surgical pathologists should be aware of the presence of both ectopic epididymal ducts and efferent ductules that can occur in TAs, in order to avoid misinterpretation as transected, functional reproductive structures.

Acute pyelonephritis is a common disease, the clinical signs and symptoms of which have been well known for many years. Clinical observation was made from 342 cases of adult with acute pyelonephritis in the department of urology and internal medicine, Kyung Hee University Hospital, from March 1986 to February 1992. Intravenous pyelography(I.V.P.) and Voiding cystourethrography(V.C.U.G.) had very little diagnostic value as well as predictive value of prognosis and complication in adult with acute pyelonephritis. But there was screening value in male patients and female patients who had combined urinary tract anomaly or disease. The most common causative organism was E. coli(81.1%). In drug sensitivity test, nearly all Gram negative organisms were resistant to Ampicillin, which previousely was mainly used to acute pyelonephritis. Gentamicin resistant organisms are still being relatively increased. Amikacin and Quinolone derivatives were very sensitive drug to all Gram negative organism.

Between May, 1987 and July, 1991, 27 renal staghorn calculi were treated with EDAP LT-01 extracorporeal shock wave lithotriptor as monotherapy. Of the staghorn calculi 18 were complete and 9 incomplete staghorn. Of the patients 5 had urinary tract infection before treatment. Stone size in longest diameter was up to 4cm in 37.0% of the cases, 4 to 9cm in 59.2% and longer than 9cm in 3.7%, including complete or partial staghorn stones. Complete response rate was 59.3%, including complete staghorn in 44.4 % and partial staghorn in 14.8%. In the complete response cases, the number of shocks used varied from storage 60 to storage 2770 at 5/sec frequency, 100% adjust power. Complete response rate was not related with hydronephrosis, size of stones and configuration or the stones, but it was related with chemical composition of the stone. In the cases of struvite stones, they needed fewer number of shocks than any other composition for complete response. Of the stones 25.9 % were treated after double-J stents were inserted. Over aI1 25.9% of the patients needed ancillary measures, including ureteroscopic removal in 11.1%, repeated ESWL for steinstrasse in 11.9% and litholapaxy in 3.7%. Of the cases 11 developed post treatment fever and they were treated with antibiotics without clinical problems, therefore urinary tract infection is no longer contraindication of ESWL. The ESWL monotherapy is one of the recommendable treatment method for staghorn calculi.

The KFDA (Korea Food & Drug Administration) has performed a collaborative toxicogenomics project since 2003. Its aim is to construct a toxicology database of 12 compounds administered to mice at initial phase. We chose 6-MP (6-mercaptopurine) which has been used in the treatment of childhood leukemia. It was administered at low (0.224 mg/kg) and at high (2.24 mg/kg) dose (5 mice per group) intraperitonealy to the postnatal 6 weeks mice, then the serum and liver were collected at the indicated time (6, 24 and 72 h) after scarification. Serum biochemical markers for liver toxicity were measured and histopathologic studies also were carried out. The gene expression profiling was carried out by using Applied Biosystems 1700 Full Genome Expression Mouse. By self-organization maps (SOM), we identified groups with unique gene expression patterns, some of them are supposed to be related to 6-MP induced toxicity, including lipid metabolism abnormality, inflammatory response, oxidative stress, ATP depletion and cell death. The potential toxic effects appearing as gene expression changes are dependent of the time of 6-MP but independent of the dosage of it. This study would contribute to establishment of international database as well as national one about hepatotoxicity.

Binding of clathrin assembly protein to clathrin triskelia induces their assembly into clathrin-coated vesicle (CCV) in neurons. The clathrin assembly protein gene (rCALM) was cloned from rat brain cDNA library. rCALM deduced 69 kD molecule has overall 73% amino acid homology compared with that of AP180 protein. The N-terminal domain, where amino acid sequences are very similar with AP180, harbours binding sites for clathrin and inositides, as well as possible phosphorylation sites, but the proline rich C-terminal domain is different from that of AP180. The mRNA expression of rCALM and AP180 by in situ hybridization histochemistry revealed that the rCALM mRNA was more intensely expressed than that of AP180, and the distribution patterns were different from each other. These results suggest that the rCALM mediates the assembly of clathrin in neural and supporting cells of brain, and regulates the clathrin coated-vesicle formation through phosphorylation and inositide metabolism.

Nuchal fibroma (NF) is a rare, benign soft tissue tumor of the posterior neck, but can also occur extranuchally. Usually, it is a slow-growing, asymptomatic solitary mass that occurs more frequently in middle-aged males. Histologically, hypocellular dense collagens in the dermis and subcutaneous layer are characteristic. Careful total excision is necessary for the treatment and accurate diagnosis. We report an unusual case of a NF occurring at the lateral neck deeply under platysma muscle. This lesion should be included in the differential diagnosis of soft tissue masses arising in the posterior neck or rarely in the lateral neck as in our case, especially when the diagnosis is not definite.

PURPOSE: To characterize the patterns of p53 & H-ras mutations related to invasiveness and differentiation of transitional cell carcinoma in human bladder. MATERIALS AND METHODS: Tissues from 52 patients diagnosed as transitional cell carcinoma in the Chungbuk National University Hospital from 1992 to 1997 were used. Direct DNA sequencing was performed to detect the presence of mutated p53 and H-ras genes and to determine the types of mutations. RESULTS: 40.4%(21/52) and 11.5%(6/52) exhibited mutations in p53 and H-ras genes, respectively. In p53 gene, 26 mutations were detected in 21 specimens; 16 point mutations and 10 microdeletions-insertions in exon 7, 8, and 10, but not in exon 9. Three specimens showed mutations more than one, i.e., a triple point mutation, and two point mutation with microdeletions-insertions in p53 gene. ATG-->AAG point mutation at codon 243 was found most frequently(38.1%). Concerning the mutation of H-ras gene, 8 point mutations were detected from 6 specimens. Only one specimen showed triple point mutation. AGT-->AGA point mutation at codon 17 was the most frequent(50%). The mutation of H-ras was statistically correlated with differentiation but not with invasiveness, whereas the mutation of p53 was not statistically correlated with any of them. Mutation of both genes had correlations to differentiation(p=0.045). CONCLUSIONS: From theses results, the mutation of H-ras gene might be a useful factor to expect the progression of transitional cell carcinoma. However, the mutation of p53 gene was insufficient as a prognostic factor of transitional cell carcinoma.

An isolated unilocular renal hydatid cyst is very rare and to the best of our knowledge, no such case has been reported in the Korean literature. A 56 year old woman, who liked eating raw vegetables fertilized by dog feces, visited our department because of an incidentally found renal cyst. Ultrasonography and the computed tomography (CT) scan showed a typical daughter cyst within the 6cm sized mother cyst. We performed retroperitoneal laparoscopic cyst marsupilaization after aspiration of the cystic contents and injection of a scolecidal agent. No dissemination and no recurrence have occurred to date.

Herein, a rare case of port site metastasis, following a laparoscopic radical nephrectomy in a 62-years old male patient with a stage pT2N0M0 and Fuhrman grade III renal cell carcinoma, is reported. The patient suffered port site metastasis, with local recurrence. The port site metastasis was incidentally found in the patient during the laparoscopic examination for a laparoscopic mass resection of a local recurrent tumor. The most important appropriate surgical techniques are those where the port site metastasis can be controlled.
