Cellular oncogenes are expressed as an intrinsic part of the transformed or neoplastic phenotype. More than 60 of the known cellular oncogenes play a specific role in normal cellular development and differentiation. To examine the correlation between ras oncogene expression and the development of cervical cancer, this study investigated the reactivity of cervical intraepithelial neoplasia(CIN) and carcinoma of the uterine cervix by using anti-ras P21 mouse monoclonal antibody. The expression of ras oncogene significantly increased with the grade of malignancy from 11% in severe dysplasia, 30% in carcinoma in situ, 43% in microinvasive carcinoma, to 53% in invasive cancer. The expression of ras oncogene was not correlated with histologic type, tumor size, and nodal status of cervical cancer. It was concluded that expression of ras oncogene is related to early phase of carcinogenesis and tumor invasion of carcinoma of the uterine cervix.

Though the incidence of paragonimiasis has been remarkably decreased since 1970, it is still not a rare disease in Korea. Major problems in the diagnosis of pulmonary paragonimiasis on chest radiography are its differentiation from pulmonary tuberculosis and lung cancer. Chest radiographic findings have been described in detail, but little have been reported on CT findings. We reviewed CT findings of 10 patients with pulmonary paragonimiasis. The characteristic CT findings were similar to those on chest radiography, such as air-space consolidation (70%), nodular mass (50%), pleural effusion (40%), cystic lesion (30%), small low density within the mass (30%), linear density (20%), pneumothorax(20%), and burrow track (20%). CT depicted the cystic lesions and the burrow tracks more clearly and showed the small worm-retaining cysts within the mass that were not detectable on chest radiography. In conclusion, all of these CT findings are useful in the diagnosis of pulmonary paragonimiasis especially when differentiation from tuberculosis or lung canceris difficult on chest radiography.

Gastritis cystica superficialis (GCS) is a rare lesion which is characterized by glandular hyperplasia with regeneration and degeneration in the mucosa and muscularis mucosa. Recently, GCS is revealed as precancerous lesion, but most report has been associated with those found at the site of a gastroenterostomy. So, we report two cases with GCS who had not previous gastric surgery. A 45-year-old woman visited for epigastric discomfort and another 4Q-year-old woman for epigastric pain. They had not undergone any gastric surgery. The gastroscopy discovered one polyp on anterior wall of greater curvature, upper body and another polyp in the center of the fold of greater curvature, lower body. We removed it by snare polypectomy and the histologic finding showed the character of GCS.

PURPOSE: Pelvic floor muscle exercise (PFME) is a therapeutic option for urinary incontinence (UI). However, studies of the efficacy of PFME on UI in patients with cognitive impairment (CI) are lacking. Therefore, we evaluated the effect of PFME on UI in elderly women with mild CI. METHODS: A total of 150 women with mild CI or Alzheimer disease and UI were screened using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Cognitive function and behavioral symptoms were evaluated by the Mini-Mental State Examination and Barthel's Activities of Daily Living. The patients were randomly divided into a control group (n=46) and a PFME group (n=52, 6 sessions of PFME for 12 weeks). The primary outcome was the change in UI episodes measured with a frequency volume chart (FVC). The secondary outcomes were other FVC parameters and the ICIQ-SF scores. RESULTS: A total of 82 women (control group: 40 and PFME group: 42) completed the study. After 12 weeks of PFME, the mean number of UI episodes per 24 hours decreased by 1.6 (from 3.3 to 1.7) in the PFME group and by 0.5 (from 3.4 to 2.9) in the control group (P < 0.001 between groups). The mean number of micturition episodes and total ICIQ-SF scores improved in the PFME group to a significantly greater extent than in the control group (P<0.001). CONCLUSIONS: Supervised PFME can be a good therapeutic option for improving UI in elderly women with CI.

PURPOSE: Rotavirus is the main cause of infantile diarrheal disease worldwide, especially in patients 3-24 months of age. Infants younger than 3 months of age are relatively protected by transplacental antibody. So the purpose of this study is to evaluate the clinical features and severity of neonatal rotaviral gastroenteritis less than 1 month of age. METHODS: A retrospective chart review was established of 62 neonates less than 1 month of age and with a diagnosis of rotaviral gastroenteritis who had been admitted to Pochon CHA University between June 2002 through July 2004. The rotavirus was examined by stool latex agglutination. RESULTS: During 2 years, the total number of admitted patients for rotaviral gastroenteritis was 688 and among these, less than 1 month of age accounted for 9% (62). The occurrence was generally even distribution from January to July (7.14+/-1.0) but since then decreased (2.4+/-1.8). The most common chief complaint was mild fever (46%) when admitted which subsided within 1 hospital day in most patients. 4 patients had seizure and cyanosis with no typical symptoms of rotaviral gastroenteritis. During admission, all the patients had diarrhea. 17% of the patients had leukocytosis and positive C-reactive protein. In one patient, stool occult blood test was positive but there was no necrotizing gastroenteritis evidence. The mean period of hospital day was 5.8+/-2.5 and breast-milk feeding was 62.9%. CONCLUSION: Neonatal rotaviral gastroenteritis is not a rare disease. Most patients have fever and diarrhea and improve through conservative therapy but a few patients may have severe complications so we must be more cautious about the hygiene for prevention.

PURPOSE: The authors applied fetal stabilization and evaluated its efficacy as a therapeutic modality in the management of several congenital anomalies that can lead to perinatal respiratory distress, such as a congenital diaphragmatic hernia (CDH), large cervical lymphangioma or gastroschisis, etc. METHODS: Between Oct. 2000 and Dec. 2004, 12 newborns, with a congenital diaphragmatic hernia or gastroschisis, were observed and fetal stabilization was applied to 4 neonates. Their clinical characteristics were then retrospectively reviewed. The protocol of this procedure was as followed, (1) monitoring of the fetal respiratory movement and heart beat using Doppler ultrasonography, (2) the intravenous administration of morphine (20 to 30 mg) and diazepam (5 mg) to the mother, (3) proceed to a cesarean section when any interruptions in the fetal movement were confirmed, (4) an intravenous injection of a pancuronimum (0.5 mg) through the umbilical vein, (5) an immediate tracheal intubation before disruption of the placenta, (6) clamping of the umbilical cord, (7) attempt a mechanical ventilation after delivery, (8) maintain percutaneous intravenous catheterization (PIC) and (9) evaluation of the neonate. RESULTS: Of the 10 neonates with a CDH and the 2 with gastroschisis, fetal stabilization was applied to 3 CDH and 1 gastroschisis neonates, respectively. The survival rates were 85.7% that of conventional therapy, 66.7% for fetal stabilization in the CDH neonates and 100% for those with gastroschisis. Relatively, in those with a CDH where fetal stabilization was applied, large defects were observed and they were diagnosed at an earlier period, which could affect the mortality. CONCLUSION: In our experience, fetal stabilization seems to be useful as another alternative therapeutic modality for the control of respiratory distress in the management of a CDH and gastroschisis. However, further experiences with more clinical results will be required

PURPOSE: We evaluated the impact of bladder neck stiffness on lower urinary tract symptoms in the patient with benign prostatic hyperplasia using elastography. MATERIALS AND METHODS: A total of 384 patients divided into three different groups according to the bladder neck stiffness based on ultrasound with elastography. Patients age, prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), prostate volumetric parameters, residual urine volume, and laboratory data were collected and compared among the three groups. RESULTS: Group 1 (n=121) showed low stiffness in both bladder neck adenoma. Group 2 (n=157) showed low to intermediated stiffness, and group 3 (n=106) showed significantly higher stiffness of bladder neck and adenoma compared to adjacent prostatic tissue. Significant differences among the 3 groups were found in the total prostate volume, transition zone volume, transition zone index, total IPSS, IPSS-voiding, IPSS-storage, residual urine volume, and quality of life. As the stiffness increased, prostate volumetric parameters, and residual urine volume were increased, and lower urinary tract symptoms became exacerbated. No significant difference was found in the patients' age and PSA. CONCLUSIONS Bladder neck stiffness affected the lower urinary tract symptoms and prostate volumetric parameters. These findings suggest that the change of bladder neck stiffness can be a novel parameter for the development of lower urinary tract symptoms/benign prostate hyperplasia.

BACKGROUND/OBJECTIVES: An increasing life expectancy in society has burdened healthcare systems substantially because of the rising prevalence of age-related metabolic diseases. This study compared the effects of animal protein hydrolysate (APH) and casein on metabolic diseases using aged mice.MATERIALS/METHODS: Eight-week-old and 50-week-old C57BL/6J mice were used as the non-aged (YC group) and aged controls (NC group), respectively. The aged mice were divided randomly into 3 groups (NC, low-APH [LP], and high-APH [HP] and fed each experimental diet for 12 weeks. In the LP and HP groups, casein in the AIN-93G diet was substituted with 16 kcal% and 24 kcal% APH, respectively. The mice were sacrificed when they were 63-weekold, and plasma and hepatic lipid, white adipose tissue weight, hepatic glucose, lipid, and antioxidant enzyme activities, immunohistochemistry staining, and mRNA expression related to the glucose metabolism on liver and muscle were analyzed. RESULTS: Supplementation of APH in aging mice resulted in a significant decrease in visceral fat (epididymal, perirenal, retroperitoneal, and mesenteric fat) compared to the negative control (NC) group. The intraperitoneal glucose tolerance test and area under the curve analysis revealed insulin resistance in the NC group, which was alleviated by APH supplementation. APH supplementation reduced hepatic gluconeogenesis and increased glucose utilization in the liver and muscle. Furthermore, APH supplementation improved hepatic steatosis by reducing the hepatic fatty acid and phosphatidate phosphatase activity while increasing the hepatic carnitine palmitoyltransferase activity. Furthermore, in the APH supplementation groups, the red blood cell (RBC) thiobarbituric acid reactive substances and hepatic H 2 O 2 levels decreased, and the RBC glutathione, hepatic catalase, and glutathione peroxidase activities increased. CONCLUSIONS APH supplementation reduced visceral fat accumulation and alleviated obesity-related metabolic diseases, including insulin resistance and hepatic steatosis, in aged mice. Therefore, high-quality animal protein APH that reduces the molecular weight and enhances the protein digestibility-corrected amino acid score has potential as a dietary supplement for healthy aging.
