A relatively rare and puzzling tumor of the testicular tunic is reported. The tumor, so called a fibrous pseudotumor of testicular tunics, in presented because of the clinical dilemma this rare entity causes urologists and pathologists. This report demonstrates the necessity for familiarity with testicular pseudotumors in order to avoid an unnecessary orchiectomy.

Nitrofurazone is a well known sensitizer and is widely used particularly in surgical department for the treatment of secondary infection, but the reports of all ergic contact dermatitis to nitrofurazone are rare in Korean literature. We experienced a case of allergic eontact dermatitis to 0.2% nitrofurazone in 31-year-old female after dressing the grafted wound on the left index finger with the gauze embedded with 0.2% nitrofurazone olintmnt. The patch test results revealed a strong positve reaction to 0.2% nitrofurazone ointment after 48 hours.

PURPOSE: To evaluate US and CT characteristics of small renal cell carcinomas with diameter less than 3cm. MATERIALS AND METHODS: We retrospectively analysed US and CT findings of the small renal cell carcinomas which were surgically confirmed. We analysed echogenicity, peritumoral hypoechoic rim, intratumoral cysts on US. We analysed CT with viewpoints of tumor margin, growth pattern, renal contour change, attenuation on pre- and postcontrast scan, homogeneity, and perirenal changes. RESULTS: The US characteristics of the small renal cell carcinomas were hyperechogenicity(89%), peritumoral hypoechoic rim(66%) and intratumoral cysts(44%). They had relatively well-defined margin(90%), smooth and round contour(90%), endophytic growth pattern(65%), and outward bulging of renal contour(75%) on CT. They had iso- or high attenuation(87%) on precontrast CT, and were relatively homogeneous low-attenuated on postcontrast CT. CONCLUSION: The constellation of US and CT findings may be helpful in the diagnosis and understanding of the internal architecture of the small renal cell carcinomas.

BACKGROUND AND OBJECTIVE: House dust mites have been known as the most important allergens in respiratory allergic disease. Since environmental factors may have influences on the pathogenesis of allergic disease, the study using Korean house dust mites for immune and biologic reactions in house dust mite-sensitive allergic disease is considered as significant. MATERIAL AND METHOD: We made two in-house allergenic extracts of Korean house dust mites (D. farinae and D. pteronpsssinus) and performed this study for the allergen standardization by in vivo methods and for the evaluation of the reliabilities for clinical applications. RESULT: As a results of biologic standardization using skin prick test teachnique, the activity of 1: 1,500w/v of D. farinae extract was estimated 1,000 biology unit(BU), concentration that elicits a wheal of the same size as that of histamine dihydrochloride 1mg/ml. The activity of 1: 1,000w/v of D. pteronyssinus was condiered as 1,000BU. The activity of 1:100w/v of both D. farinae and D. pteronpssiuns extracts were considered as 100,000 Allergy Unit(AU), based on intradermal skin testing of 30 subjects with strong sensitive reaction. The concordant rates between results of skin prick test done with 5,000BU/ml concentration of in-house allergenic extracts and thoae with the commercially available allergen(Bencard Co., UK) were 84.6% and 81.0% for D. farinae and D. pteronpssinus, respectively. The wheal erythema size and A/H ratios induced by in-house extracts were significantly correlated with those induced by Bencard allergen. CONCLUSION: This results suggest that in-house extracts of the whole bodies of two house dust mites have good allergenic activities in vivo. It is considered to be clinically useful and reliable allergenic extracts.

OBJECTIVE: SCC-Ag(Squamous Cell Carcinoma Antigen) is a tumor marker for patients with squamous cell carcinoma of the uterine cervix. It has shown that the SCC-Ag was well related with the response of cancer therapy and course of cervical cancer. The aim of this study is to investigate whether the presence of pelvic lymph node metstasis can be predicted by the measurement of the preoperative SCC-Ag levels in the patients with early staged squamous cell carcinoma of cervix. METHODS: The preoperative serum SCC-Ag levels were measured in 45 patients with stage I-II squamous cell carcinoma of cervix undergoing radical hysterectomy from September 1995 to December 1997. The serum SCC-Ag levels were analyzed for the clinicopathologic characteristics and other prognostic factors using univariate and multivariate analysis. RESULTS: The serum SCC-Ag levels of the patients exhibited pelvic lymph node metastasis were above 4.8ng/ml. An elevated preoperative serum SCC-Ag level, and tumor size were independent predictors for the presence of lymph node metastasis(p<0.01). CONCLUSION: The determination of the preoperative serum SCC-Ag levels provides a new prognostic factor in early staged cervical cancer.

Isolated rat thoracic aorta which is pharmacologically precontracted by phenylephrine induces photorelaxation when exposed to long wave length UV-light. The aim of the present study was to characterize the mechanism of UV-light induced by photorelaxation in the rat aorta. 1. UV light relaxed both endothelium-intact and -denuded rat aortic rings contracted by phenylephrine. The magnitude of relaxation on UV light was dependent on the exposure time and slightly greatly in endothelium-denuded rings than in endothelium-intact preparations. 2. L-NAME (10 nM-100 uM) but not D-NAME completely inhibited the photorelaxation in a concentration dependent manner. 3. The UV-induced relaxation was inhibited by methylene blue (1 -100 uM), and verapamil (100 nM), and removal of extracellular Ca2+. In contrast, UV-light induced photorelaxation was potentiated by N(w)-nitro-Larginine (L-NOARG) treatment. 4. In immunocytochemical analysis of UV-light induced iNOS and eNOS expression in rat aortas, at which expression levels were increased in a time-dependent manner on UV-irradiation in aortic endothelium and smooth muscle, respectively. These results suggest that UV light-induced photorelaxation may be due to nitric oxide from exogenously administered L-arginine as well as endogenous nitric oxide donors such as amino acid and arginine derivatives. Additional suggestion is that UV light stimulates the expression of nitric oxide synthases, and its activity for nitric oxide generation is dependent on cytosolic Ca2+ originated from extracellular space.

Traumatic dislocation of the testis occurs when a normally distended testis assumes, as a result of trauma, a non-scrotal position by passing along fascial plane and through normal anatomic aperture. Less than 50 cases of true traumatic dislocation have been reported. The etiology, classification and treatment of testicular luxation are reviewed briefly. If efforts at closed reduction are unsuccessful, management requires surgical exploration and orchiopexy. The prognosis for recovered or fertility potential after this repair of dislocation of the testis is good. We report the case that one testis has traumatic dislocation with a ruptured vas deferens and the other has a primary spermatogenic defect.
