We report a case of primary transitional cell carcinoma developed in bladder vdiverticulum with brief review of literatures. Patient was a 71 year-old man who had painless gross hematuria for 10 days. Excretory urogram showe a large diverticulum in the bladder. At cystoscopy a 0.5 x 0.5cm sized papillary mass was seen on diverticular mucosa. Urine cytology revealed class V transitional cell carcinoma. At pelvic CT, metastatic evidence was not seen. We carried out partial cystectomy involving diverticulum under the diagnosis of primary transitional cell carcinoma developed in vesical diverticulum. The histopathologic diagnosis was grade III, stage A transitional cell carcinoma combining with carcinoma in situ.

Rehmannia glutinosa is a perennial medicinal plant belonging to the family Scrophulariaceae with more than 300 species known in the world, especially in temperate regions. Its roots have been used widely in Korea for medicinal purposes. However, it is commonly infected by various pathogens during storage, causing great damage to the roots, and impedes the intensive farming of the crop. Therefore, an attempt has been made to isolate and screen a resistance gene against the pathogen Fusarium oxysporum using differential display. We treated salicylic acid (SA), and isolated a resistance gene that responds to SA. As a result, we found that SA was involved in plant defense mechanism in pathogenicity tests with SA treated and non-treted plants, and we isolated a partial PR-la gene through differential display polymerase chain reaction (DD-PCR) method.

PURPOSE: Preamplifier and amplifier are very important parts for developing a portable counting or imaging gamma probe. They can be used for analyzing pulses containing energy and position information for the emitted radiations. The commercial Nuclear Instrument Modules (NIMs) can be used for processing these pulses. However, it may be improper to use NIMs in developing a portable gamma probe, because of its size and high price. The purpose of this study was to develop both preamplifier and amplifier and measure their performance characteristics. MATERIALS and Methodes: The preamplifier and amplifier were designed as a charge sensitive device and a capacitor resistor-rsistor capacitor (CR-RC) electronic circuit, respectively, and they were mounted on a print circuit board (PCB). We acquired and analyzed energy spectra for Tc-99m and Cs-137 using both PCB and NIMs. Multichannel analyzer (Accuspec/A, Caberra Industries Inc., Meriden Connecticut, U.S.A) and scintillation detectors (EP-047 (Bicron Saint-Gobain/Norton Industrial EP-047 (Ceramics Co., Ohio, U.S.A) with 2"x2" NaI (T1) crystal and R1535 (Hamamatsu Photonics K.K., Electron Tube Center, Shizuoka-ken, Japan) with 1"x1"NaI (T1) crystal) were used for acquiring the energy spectra. RESULTS: Using PCB, energy resolutions or EP-047 detectors for Tc-99m and Cs-137 were 12.92% and 5.01%, respectively, whereas R1535 showed 13.75% and 5.19% of energy resolution. Using the NIM devices, energy resolutions of EP-047 detector for Tc-99m and Cs-137 were measured as 14.6% and 7.58%, respectively. However, reliable energy spectrum of R1535 detector could not be acquired, since its photomultiplier tube (PMT) requires a specific type of preamplifier. CONCLUSION: We developed a special preamplifier and amplifier suitable for a small sized gamma probe that showed good energy resolutions independent of PMT types. The RESULTS indicate that the PCB can be used in developing both counting and imaging gamma probe.

Buerger's disease (thromboangiitis obliterans) is an inflammatory, nonatherosclerotic, occlusive disease of small- and medium-sized arteries and veins that involves distal vessels of the extremities. Patients show symptoms related to ischemia of distal lower extremities and upper extremities (claudication, gangrene, rest pain, distal cyanosis). We report a case of progressive ascending motor weakness of the lower extremities in a Buerger's disease patient due to a metastatic bone tumor on the T3 level after lumbar epidural block and continuous cervical epidural block.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman. Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter. On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials. Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.

Progressive zosteriform macular pigmented lesion(PZMPL) is a chronic pigmentary dermatosis similar to progressive cribriform and zosteriform hyperpigmentation(PCZH). This dermatosis described by Simoes in 1980 is characterized by a uniformly tanned macular pigmented lesion in a zosteriform distribution preceded by multiple pruritic macular pigmentation in a part of the dermatome for a period. PZMPL is not a fully understood disease entity but it is thought to be a variant of PCZH. It is differentiated from PCZH by accompanying pruritus as a prodromal symptom, a characteristic clinical course, and histological findings such as pigmentary incontinence. We report herein a case of PZMPL in a 17 year-old girl with the pigmentary skin lesion extending from the left forearm to the left chest along the Blaschkos line. The histological findings revealed increased melanin pigments in the basal layer and focal pigmentary incontinence in the upper dermis. To our knowledge, this case is the first report of PZMPL in korea thought to be the same case reported by Simoes.
