M-mode, pulsed Doppler and Doppler color flow mapping, in addition to two-dimensional echocardiography, have greatly improved imaging of the fetal heart through identification of abnormal cardiac anatomy and rhythm in utero. The early detection of cardiac disturbance in utero permits alteration in obstetric management such as delivery in a high-risk center for optimal neonatal care and/or decision in optimal delivery time. We report two cases of the neonatal arrhy-thmia which were observed by fetal echocardiography. In the first case, female baby showed neonatal arrhythmias including tachycardia and brady-cardia until 3 days after birth, and then turned to bradyarrhythmia due to non-conducted atrial bigeminy. These events lead us to review the fetal echocardiographs of the patient carefully. Premature atrial contractions were observed in her fetal echocardiography. At 2 months after birth, the patient's electrocardiogram showed normal sinus rhythm. Severe neonatal bradycardia of the second case was due to congenital complete heart block, identified clearly by electrocardiogram after birth. This case also showed complete heart block in her fetal echocardiography. After insertion of the temporary pacemaker, cardiomegaly was improved. Both the neonate and the mother had positive anti-SSA/Ro autoantibody. But any other symptoms and signs of neonatal lupus did not appear in the neonate. Patient's mother also did not show any symptoms and signs of systemic lupus erythematosus. Since the prognosis depends upon the cause of bradyarrhythmia in fetus and neonates, differential diagnosis is important in obstetric management and optimal neonatal treatment.

The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed by Stoll's egg-counting technique, and praziquantel was administered to positive cases. The egg-positive rates for Clonorchis sinensis and Metagonimus species were 9.3% and 5.5%, respectively, and the double infection rate was 3.5%. The numbers of eggs per gram (EPG) of feces of C. sinensis and Metagonimus sp. were 918 +/-1.463 and 711+/-947, respectively. The egg-positive rates for C. sinensis and Metagonimus sp. in the riverside area were 14.2% and 8.4%, respectively, which were significantly higher than those of the inland area (3.2% and 1.7%, respectively). The egg-positive rates of C. sinensis and Metagonimus sp. in males (16.7% and 10.0%) were significantly higher than those of females (3.5% and 1.8%). However, there were no significant differences of EPG values between localities and sexes. The prevalence of clonorchiasis and metagonimiasis in this survey was significantly lower than that in the previous reports. However, there is still a high prevalence of infection with C. sinensis and Metagonimus sp. in this region, especially in the riverside area.

PURPOSE: The purposes of this study were to compare the degree of anger expression, assertive behavior, and self-esteem between a nursing student group and an educational student group, and to identify factors affecting their self-esteem. METHODS: This study adopted the descriptive comparative design. Data were collected by interviewing 97 nursing students and 89 educational students from three nursing schools and one educational school in Daegu, Korea from November to December, 2008. RESULTS: Major findings of this study were as follows. 1) The educational student group had a higher self-esteem score than the nursing student group. 2) There were significant correlations among anger expression, assertive behavior, and self-esteem. 3) Self-esteem was significantly associated with Grade Point Average (GPA) and assertive behavior in the nursing student group with 17.2% variance, and with assertive behavior and anger-out in the educational student group with 24.1% variance. CONCLUSION: These results may contribute to better understanding of hurt, anger expression, assertive behavior, and self-esteem in nursing students and educational students. Based on the results, there, it is required to develop programs that prompt students' self-esteem.

A granular cell tumor (GCT) is a relatively rare benign tumor that has been seldom reported since Abrikossoff first described it as a granular cell myoblastoma in 1926. While GCTs can occur anywhere in the human body, they are very rarely observed in the gastrointestinal tract and are especially rare in the large intestine. Most GCTs are small and asymptomatic and are often found by endoscopy, upper gastrointestinal series, and autopsy. We report two cases in which a submucosal tumor in the cecum was accidentally discovered by colonoscopy and was subsequently removed by colon polypectomy and endoscopic mucosal resection. Immunohistochemical analysis of the samples confirmed both cases as GCT. The literature review and reports of other growths in the gastrointestinal tracts support the necessity for proper identification of GCTs within the body to differentiate them from more malignant tumors.

To evaluate the role of nitric oxide (NO) in IFN-gamma production and apoptosis of splenocytes in genetically different strains of mice with toxoplasmosis, BALB/c (a toxoplasmosis resistant strain) and C57BL/6 (a toxoplasmosis susceptible strain) mice were infected with Toxoplasma gondii cysts orally and subsequently injected intraperitoneally with aminoguanidine, an iNOS inhibitor (AG; 35 mg/kg per mouse daily for 14 days). When BALB/c or C57BL/6 mice were infected with T. gondii without AG treatment, number of brain cysts, NO and IFN-gamma production by splenocytes, and percentages of apoptotic splenocytes were increased compared to uninfected control mice without AG treatment. AG treatment increased the number of brain cysts, and reduced NO and IFN-gamma production in T. gondii-infected C57BL/6 mice. In contrast, in T. gondii-infected BABL/c mice, the number of brain cysts, and NO and IFN-gamma production of splenocytes was not altered by treatment with AG. However, the percentages of apoptotic splenocytes in T. gondii-infected BALB/c or C57BL/6 mice were not affected by AG treatment. These results suggest that NO modulates IFN-gamma production in T. gondii-infected C57BL/6 mice, and that NO is involved in mediating a protective response in toxoplasmosis susceptible, but not resistant, mice strain during acute infection.

OBJECTIVE: This study was to investigate the expression of CDK inhibitors, p27(kip1) and p57(kip2) in mouse endometrium during the estrus cycle and pregnant period. METHODS: Total RNA and protein were extracted from endometrium of mouse sacrificed at diestrus, proestrus, estrus, and metestrus cycle, and at day 1-6 post-coitum (p.c.), then semi-quantitative RT-PCR and western blotting of p27(kip1) and p57(kip2) was carried out. RESULTS: p27(kip1) and p57(kip2) mRNA was highly expressed in diestrus and proestrus stage than estrus and metestrus stage. In comparison with estrus cycle, p27(kip1) and p57(kip2) mRNA level was highly maintained in gestational endometrium (except p27(kip1) of day 5 p.c). p57(kip2) protein level was relatively low from day 1 p.c. to day 4 p.c. But it was significantly increased in day 5 p.c. and day 6 p.c. CONCLUSION: These results show that p27(kip1) and p57(kip2) may play a role in endometrial differentiation for regular estrus cycle and implantation, and especially p57(kip2) may play an essential role in endometrial differentiation for maintenance of implantation.

OBJECTIVE: This study was to investigate the expression of CDK inhibitors, p27kip1 and p57kip2 during the growth and differentiation of mouse placenta. METHODS: Total RNA and protein were extracted from placenta of mouse sacrificed at day 12, 14, 16, 18 post-coitum (p.c.), then semi-quantitative RT-PCR and western blotting of p27kip1 and p57kip2 was carried out, respectively. RESULTS: p27kip1 mRNA was highly expressed in 18 days p.c. then other groups. But, p57kip2 mRNA expression was high in 12, 14, and 16 days p.c., then decreased in 18 days p.c. p27kip1 expression pattern was similar with mRNA. But, p57kip2 was higher in 14 days p.c. than other groups. CONCLUSION: This result shows that p27kip1 may play a role in late period of mouse placental development, and p57kip2 may play a role in middle period of mouse placental development.

OBJECTIVE: This study was to investigate the localization of CDK inhibitor, p57(kip2) in mouse endometrium during the estrus cycle and pre- and peri-implantation periods. METHODS: The p57(kip2) protein was immunostained from endometrium of mouse sacrificed at diestrus, proestrus, estrus, and metestrus cycle, and at day 1-6 post-coitum (p.c.). RESULTS: The staining in the luminal epithelium was very weak in comparison with glandular and stromal cells. In diestrus stage, immunoreactivity of p57(kip2) was heterogeneously strong in parts of decidualized or degenerated stromal cells. In proestrus stage, strong immunoreactivity p57(kip2) was largely found in stromal cells. But, p57(kip2) was showed low immunoreactivity in estrus stage. In metestrus stage, immunoreactivity of p57(kip2) was heterogeneously strong in decidualized stromal cells. In day 1-2 p.c., immunoreactivity of p57(kip2) was low in some endometrial stromal cells. In day 3-4 p.c., immunoreactivity of p57(kip2) was strong in some endometrial stromal cells. In day 5-6 p.c., immunoreactivity of p57(kip2) was strong in decidual cells. CONCLUSION: These suggest that p57(kip2) may play an essential role in endometrial differentiation for maintenance of implantation, especially decidualization of endometrial stromal cells.
