One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or

To evaluate the effects of reflected glare on eyes, authors assessed the periodic health examination(1991-1996) and self-administered questionnaire data of a semiconductor producing company. The 13 lead frame(LF) department workers have been exposed to high reflected glare in the process for examining the silver plating products. We compared the data of connector(14) and clerical(12) workers as the non-exposed ones. Among LF department workers, 100% felt their visual acuity worsened(connector:81.8%, clerical:85.7%), and 70% had worn the glasses or contact lenses(connector :14.3 %, clerical :40%) since working at the company. Major ophthalmic symptoms of the LF workers are asthenopia, tearing, decreased visual acuity, congestion and glare. Decrease of visual acuity by Hahn's line change of the LF workers is significantly high during a 5-year follow-up(p<0.05 by simple regression) compared with connector, clerical workers.

Korean Journal of Urology 2003;44(5):452-459
PURPOSE: The aim of this study was to demonstrate that the combined systemic administration of apomorphine (APO) and sildenafil have a synergistic effect on the erection in conscious rabbits. MATERIALS AND METHODS: The erections of the male New Zealand White rabbits (2-3kg, n=12) were assessed by measuring the length of the uncovered penile mucosa (LUPM) and duration of the erection, both before and after the intravenous administration of agents. After the injection of APO (0, 0.05, 0.1, 0.4mg/kg), sildenafil was administered intravenously in a dose-response manner (0.5, 1, 5mg/kg), followed by measurements for 0-120 minutes. In additional experiments, the effect of increasing the dosages of sildenafil, combined with APO, on blood pressure were evaluated. RESULTS: The intravenous administration of sildenafil caused a concentration dependent increase in the LUPM. There was a statistically significant increase in the LUPM with the administration of APO compared with no administration. The dosages of sildenafil and APO showing the greatest efficacy of sildenafil potentiation were 1mg/kg and 0.1 mg/kg, respectively. The intravenous administration of APO at a dose of 0.1mg/kg was more effective than those of 0.05 and 0.4mg/kg, with dosages of sildenafil of 0.5 and 1mg/kg. There was no additional increase in the duration of erection on the administration of APO. The intravenous administration of sildenafil caused a concentration dependent decrease in blood pressure, but there was no additional decrease on administration of the APO. CONCLUSIONS: We have shown that apomorphine elicits a stronger response on the erection induced by sildenafil in conscious rabbits, with no additional decrease in blood pressure.

Malakoplakia is an uncommon granulomatous disease most frequently found in the bladder or ureter. Howevcr, it has been reyorted in almost every ather organ and structure, the colon is the most common site of malakoplakia outside the urogenital tract and colonic carcinoma is the most commonly associated disease. A case of malakoplakia of the colon in a 54-year-old female is reported. Sigmoidoscopy revealed multiple whiteyellowish nodules simulating polypoid lesion at 10cm from the anal verge. The biopsy showed characteristically comprised submucosal proliferations of histiocyte and chronic inflammatory cells with typical cytoplasmic inclusions known as Michaelis-Gutmann bodies. Intravenous pyelogram showed no evidence of involvement of the urinary system. These nodules were removed by endoscopic polypectomy, So far, this is the first case of isolated colonic malakoplakia in Korea.

PURPOSE: Nitric oxide (NO) and phosphodiesterases (PDEs) play key roles in mediating relaxation of corpus cavernosal smooth muscle by increasing intracellular cGMP level. Here, we investigated effects of NO-donor (sodium nitroprusside, SNP) and penile specific type-V PDE inhibitor (zaprinast) in human and rabbit corpus cavernosal cells and tissues in vitro. MATERIALS AND METHODS: The cultured smooth muscle cells and tissues of human and rabbit corpus cavernosum were treated with increasing concentrations of SNP or zaprinast for 5 and 20 minutes, respectively, and intracellular cGMP levels were measured by radioimmunoassay. Organ bath study was performed to measure the relaxation effects of drugs on precontracted corpus cavernosal muscle strips. RESULTS: Although both NO-donor and type-V PDE inhibitor effectively stimulated the accumulation of cGMP in a dose-dependent manner, magnitude of cGMP increase and specificity of drug were found to be species-dependent. In human corpus cavernosal tissues, cGMP was increased upto 10- and 5-folds by SNP and zaprinast, respectively. However, magnitude of increase was much less in cultured smooth muscle cells. In rabbit, SNP effect was most prominent in cultured cells and effects of SNP and zaprinast were modest in tissues. Both agents also resulted in effective relaxation of human and rabbit cavernosal tissue strips. Similar patterns of dose-response curves were shown between results from the organ bath studies and cGMP radioimmunoassay with cavernosal smooth muscle cells. CONCLUSIONS: Present results show that effects of SNP and zaprinast are not coincident in different species, suggesting possible species-specificities of these two agents. Measurement of cGMP changes in cultured cavernosal smooth muscles cells could be reflected to the relaxation effects of drugs on corpus cavernosal muscle strips.

We experienced a case of non-Hodgkin's lymphoma presented only as right side pleural effusion, that is primary effusion lymphoma (PEL), in a 75 year-old male patient in Korea where is the endemic area of tuberculosis. He visited our hospital complaining of exertional dyspnea. He did not have B symptoms. The breathing sound was decreased on the right side chest, but we could not find external lymphadenopathy or hepatosplenomegaly on physical examination. Simple chest radiograph showed right side pleural effusion. The cells of pleural fluid were lymphocyte-predominant and the pH, protein, lactate dehydrogenase, adenosine deaminase of the fluid was 7.31, 38 g/L, 381 U/L, 31 U/L, respectively. The biopsy specimen of the parietal pleura was diagnosed as non-Hodgkin's lymphoma of small lymphocytic type. Computed tomograph of the chest, abdomen and pelvis, and the biopsy of bone marrow were negative for disease. We tried up to 3 cycles of chemotherapy with adriamycin, vincristine, cyclophosphamide and prednisolone and there was a marked decrease in the amount of the pleural effusion.

Meigs' sydrome is a relatively uncommon and the unusual condition of ascites and fluid in the chest associated with benign and solid tumors of the ovary with the gross appearance of a fibroma. The mechanism of this syndrome is not completely understood, but various lymphatics through the diaphragm seem the likely route for ascitic fluid into the chest. We present a case of Meigs' syndrome associated with fibrothecoma and elevate CA 125 with the brief review of literature.

Phantom limb pain is a painful sensation from an absent limb. The onset of pain is generally early, with 75% of patients developing pain within the first few days after amputation. The frequency and duration of attacks tend to be reduced with time, although the prevalence and intensity remain constant. We report here a case of a 38-year-old man who exhibited the signs and symptoms of phantom limb pain due to the above-knee amputations of both legs. He was not responded to opioid therapy and a continuous intravenous infusion of ketamine, an N-methyl-D-aspatate receptor antagonist, reduced his severe pain.
