The purpose of this study was to investigate the characteristics or the potassium channels existing in the rat urinary bladders. Smooth muscle strips of rat detrusor urinae were examined by isometric myography. Relaxation responses of detrusor muscle strips to the three potassium channel openers pinacidil, a cyanoguanidine derivative, BRL 38227, a benzopyran derivative and RP 52891, a tertrahydrothiopyran derivative were examined. The potassium channel openers reduced the basal tone, and the rank order of potency was RP 52891>pincidil>BRL 38227. Procaine, an inhibitor of the voltage-sensitive potassium channel tended to increase the basal tone, but it did not affect the relaxant effects of the calcium-activated potassium channel opener did not antagonize the relaxant effects, but it reduced the Emax of RP 52891 and BRL 38227. Glibenclamide, an inhibitor of the ATP-sensitive potassium channel, antagonized the relaxant effects of pinacidil, RP 52891 and BRL 38227 reducing the Emax of RP 52891 and BRl 38227. Galanin which inhibits secretion of insulin through opening the ATP-sensitive potassium channels in pancreatic β-cells rather increased the basal tone of the isolated detrusor strips. These results suggest that the urinary bladder of the rat has mainly the ATP-sensitive, glibenclamide sensitive potassium channel, which is a different type from that in the pancreatic β-islet cells.

OBJECTIVES: Stigma resistance is an individual capacity to fight the stigma of mental illness and is an issue of ongoing research regarding the stigma. The aim of this study was to evaluate predictors of stigma resistance in patients with bipolar disorder. METHODS: Demographic, clinical, and psychosocial data were collected from 102 bipolar patients in a university mental hospital. Stigma resistance was measured using a subscale of the Internalized Stigma of Mental Illness Scale. Patients completed self-reported questionnaires including items on self-esteem, hopelessness, social support, and social conflict. RESULTS: Stigma resistance showed positive association with functioning, self-esteem, and social support, and showed negative association with depressive symptoms, hopelessness, and social conflict. In multivariate analysis, stigma resistance was predicted by sex, education, and self-esteem. Self-esteem was the strongest predictive factor of stigma resistance. CONCLUSION: In accordance with previous studies, self-esteem was a central role of predicting stigma resistance. A program for improving self-esteem and its related psychosocial factors will be helpful to enhancing stigma resistance in bipolar patients.

PURPOSE: To evaluate the usefulness of the coaxial technique in US-guided breast core biopsy. Materials andMethods : Using the coaxial technique, US-guided breast core biopsy was performed in 49 breast lesions (40patients). Under US-guidance the 17-gauge, 13 cm long introducer needle was positioned proximal to the lesion.Once the needle was in place, the central trocar was removed and was replaced with the core biopsy needle. We usedan 18-gauge, 16-cm-long core biopsy needle with a 17 mm specimen notch. Four to eight tissue specimens wereobtained from each lesion, and the quality and quantity of specimens, procedure time, and complications and theirrate were evaluated. RESULTS: For 48 of 49 lesions, specimens were adequate for histopathologic diagnosis, andthe findings were as follows : six cases of invasive ductal carcinoma, one of ductal carcinoma in situ, 29 offibrocystic disease, eight of fibroadenoma, two of chronic inflammation, and two of sclerosing lesion. In 12lesions agreement between the pathologic results of needle core biopsy and surgical results was 100%. Theprocedure time was about 15 minutes and no significant complications were noted. CONCLUSION: In breast corebiopsy, the coaxial technique is simple and time-saving, and compared with stan-dard breast core biopsy, may alsobe less traumatic and decrease the potential risk of seeding the biopsy tract with malignant cells.

PURPOSE: Replication error is an important mechanism in carcinogenesis. The microsatellite instability (MSI-H) of colorectal cancers is associated with the development of multiple cancers. The influence of MSI-H on the development of multiple gastric cancers in sporadic gastric cancer patients has not been defined. This study was performed to reveal the association between the clinicopathologic features and MSI in sporadic gastric cancers. MATERIALS AND METHODS: Between July 2004 and March 2009, the clinicopathologic characteristics, including MSI status, were evaluated in 128 consecutive patients with sporadic gastric cancers. None of the patients had hereditary non-polyposis colorectal cancer of familial gastric cancer. The markers that were recommended by the NCI to determine the MSI status for colorectal cancers were used. RESULTS: MSI-H cancers were found in 10.9% of the patients (14/128). Synchronous gastric cancers were shown in 4 patients (3.1%). Synchronous cancers were found in 2 of 14 patients with MSI-H gastric cancer (14.3%) and 2 of 114 patients with MSS gastric cancer (1.8%; P=0.059, Fisher's exact test). Among the patients with synchronous cancer 50% (2/4) had MSI-H cancer, but 9.7% of the patients (12/124) without synchronous cancer had MSI-H cancer. MSI-H (RR, 24.7; 95% CI, 1.5~398.9; P=0.024) was related with to synchronous gastric cancer, but age, gender, family history, histologic type, location, gross morphology, size, and stage were not related to synchronous gastric cancer. CONCLUSIONS: MSI is associated with the intestinal-type gastric cancer and the presence of multiple gastric cancers in patients with sporadic gastric cancer. Special attention to the presence of synchronous and the development of metachronous multiple cancer in patients with MSI-H gastric cancer is needed.

Thromboembolic complications (TECs) are clinically important sequelae of nephrotic syndrome (NS). The incidence of TECs in children is approximately 2%-5%. The veins are the most commonly affected sites, particularly the deep veins in the legs, the inferior vena cava, the superior vena cava, and the renal veins. Arterial thrombosis, which is less common, typically occurs in the cerebral, pulmonary, and femoral arteries, and is associated with the use of steroids and diuretics. Popliteal artery thrombosis in children has been described in cases of traumatic dissection, osteochondroma, Mycoplasma pneumoniae infection, and fibromuscular dysplasia. We report of a 33-month-old girl with bilateral iliac and popliteal arterial thrombosis associated with steroid-resistant NS due to focal segmental glomerulosclerosis. Her treatment involved thrombectomy and intravenous heparinization, followed by oral warfarin for 8 months. Herein, we report a rare case of spontaneous iliac and popliteal arterial thrombosis in a young child with NS.

OBJECTIVE: To evaluate the usefulness of percutaneous umbilical blood sampling (PUBS) and prevalence of fetal infection in the pregnant women with suspicious fetal rubella infection. METHODS: Between June 1996 and May 2002 in Chonnam National University Hospital, the rubella specific IgG, IgM antibody and RT-PCR were checked in fetal blood obtained from 31 pregnant women with high risk of rubella infection. Eighteen women (58.1%) had rubella specific IgM, 11 women (35.5%) high titer of rubella specific IgG, and 2 women had a history of recent rubella vaccination within 3 months. RESULTS: PUBS was performed in all cases, successful in 27 cases (87.1%) and failed in 4 cases (12.9%). Cardiocentesis was performed in failed cases. Performing the PUBS, fetal bradycardia was observed in 7 cases (25.9%), fetal tachycardia in 1 case (14.8%), and preterm labor in 2 cases (7.4%). Performing cardiocentesis, fetal bradycardia was observed in 1 case (25.0%), fetal tachycardia in 2 cases (50.0%), and preterm labor in 1 case (25.0%). There was no fetal death. All samples of fetal blood were positive for rubella specific IgG but rubella specific IgM was detected in only 1 case. RT-PCR was negative in all cases. CONCLUSION: Fetal blood sampling is relatively safe and a great precaution is necessary before termination of pregnancy with suspicious fetal rubella infection and without typical maternal rash to reduce unnecessary termination of pregnancy. Several tests such as rubella specific IgM and PCR from placental villi, amniotic fluid, and fetal blood should be considered before termination of pregnancy.
