The present study was conducted to investigate the effect of iron-enriched cereal supplement and nutrition education program on nutritional status and life style of children. Elementary school students (n = 170) aged of 11 years old at Seoul were participated. Subjects were supplemented with iron-enriched cereal for breakfast and provided with 2 sessions of nutrition education during 3 months. Intake of carbohydrate, iron, sodium, zinc, vitamin A, vitamin B1, vitamin B2, vitamin C, niacin, and folic acid was significantly increased after cereal supplement. Caloric intake was similar to KDRIs during both before and after cereal supplement. There was no improvement on exercise and dietary habits after nutrition education. Male students tended to sleep later, wake up early, and ate snack less than female. Cereal supplement was effective on improving nutritional status, but short-term nutrition education had no effect on modification of life style. Thus, further studies are required to develop long-term education program effective on improving life style and eating habits in children.

To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.

OBJECTIVES: Estimation of the anterior lower uterine segment (LUS) thickness difference who underwent prior cesarean delivery measured with transvaginal sonography at or after 36 gestational weeks (sonographic thickness) and a ruler during elective cesarean section (operation thickness) Methods: One hundred sixty women who underwent prior cesarean delivery had the thickness of their LUS measured with transvaginal sonography at or after 36 gestational weeks. The LUS thickness was measured with a ruler during elective cesarean section. We compared group I whose LUS was fairly well visualized 4 cm or more from the uterine cervix to group II which had less than 4 cm. RESULTS: The mean sonographic thickness of LUS was 1.7 0.8 mm and that of operation thickness was 1.9 0.5 mm. The mean difference of the two (thickness difference) was 0.5 0.5 mm. In 31.3% the sonographic thickness was same as the operation thickness and in 70.7% of the total with 0.5 mm or less difference, the sonographic thickness could be regarded as accurate. The thickness difference with the sonographic thickness with 2 mm or more was smaller than those with 1 mm or less (0.4 0.5; 0.6 0.6) and that of group I was smaller than that of group II (0.4 0.4; 0.9 0.6) (p< .05). CONCLUSION: The thickness difference was 0.5 0.5 mm and it was smaller when the LUS thickness is 2 mm or over, clearly visible 4 cm or over from the cervix.

Osteoblasts from alveolar bone may have an important role in the bone regeneration for periodontium, but their culture and characterization are not determined yet. The purpose of this study was to investigate the biological characteristics of primary explant cultured osteoblasts(PECO) from alveolar bone. Osteoblasts were isolated and cultured from alveolar socket of extracted tooth in children. To compare the characteristics, osteoblasts and gingival fibroblasts were cultured with DMEM at 37degrees C, 5% CO2, 100% humidity incubator, and human fetal osteoblasts cell line(hFOB1) were cultured with DMEM at 34degrees C, 5%, CO2, 100% humidity incubator. To characterize the isolated bone cells, morphologic change, cell proliferation and differentiation were measured. Morphology of PECO was small round body or cuboidal shape on inverted microscope and was similar with hFOB1. PECO became polygonal shape with stellate and had an amorphous shape at 9th passage in culture. PECO had significantly higher activity than that of gingival fibroblasts and hFOB1 in alkaline phosphatase activity. The expression of osteocalcin and bone sialoprotein in PECO was notably increased when compared with hFOB1 and gingival fibroblasts. These result indicated that PECO from alveolar bone in children has an obvious characteristics of osteoblast, may be applied for the regeneration of bone.

BACKGROUND: Chronic pain is often associated with changes in the immune responses, which highlights the need for the aggressive pain control to obtain a better prognosis. This study examined splenic NK cell cytotoxicity in an attempt to assess the possible changes in the immune function under chronic neuropathic pain after a partial transsection of the sciatic nerve. METHODS: After confirming tactile allodynia in response to the von Frey filament, a modified lactate dehydrogenase (LDH) release assay was used to determine the cytotoxic activity of splenic NK cells on the YAC-1 cell line in C3H/HeN (H-2k) mice (n = 6). NK cells as effector cells were mixed with YAC-1 cells as target cells (1 x 10(4)/100microliter), resulting in an effector-target ratio of 1 : 25, 1 : 50, 1 : 100 in the culture medium. RESULTS: At 1 and 2 weeks after the nerve injury, all the subjects showed significant mechanical sensitivity compared with those observed before surgery. The percentage of NK cell cytotoxicity of the neuropathic mice increased significantly 1 week after the nerve injury but decreased within 2 weeks compared with the normal mice. CONCLUSIONS: In terms of the altered NK cell cytotoxicity, neuropathic pain can cause changes in the normal performance of the immune function.

PURPOSE: Cardiotoxicity following cancer chemotherapy or radiotherapy is an emerging issue for breast cancer patients. The purpose of this study was to analyze the current domestic research trends for exercise intervention for Korean breast cancer patients under chemotherapy or radiotherapy, focused on cardiovascular indices as study outcome measures and to make suggestions for future nursing studies. METHODS: A literature search was done using PubMed, CINAHL and two Korean databases to identify experimental studies reported in Korean or English between 2,000 and 2015. We identified five studies independently reviewed by two reviewers. The quality and risk of bias of the selected studies were assessed by RoBANS criteria. RESULTS: Tai-chi exercise was used in three studies and aerobic exercise programs or yoga and walking exercise in the remaining studies. Two studies evaluated cardiovascular outcomes and showed positive findings for breast cancer patients. For cardiovascular indices, heart rate and blood pressure were used. CONCLUSION: This study showed the need for conducting well-designed experimental studies including clinical cardiovascular outcomes to generate evidence on exercise intervention for cancer therapy-induced cardiotoxicity prevention. Additional studies are warranted to accelerate the potential use of exercise as a nursing intervention for cancer patients under chemotherapy or radiotherapy.

PURPOSE: A papillary carcinoma of the breast is relatively rare. Only about 1 to 2% of the breast carcinomas have been reported to be papillary carcinomas. So far, we have not found any report of a clinicopathological analysis of a papillary carcinoma in Korean women. METHODS: The records of 13 women diagnosed as having a papillary carcinoma were reviewed. The H&E and specially stained microscopic slides from each case were re-examined. The clinical data, tumor sizes, lymph node status, hormone receptor status, surgical procedures, and recurrences were analyzed. RESULTS: The 13 cases of papillary cancer represented an incidence of 1.28% of all breast cancers diagnosed at the Keimyung University Dongsan Medical Center. The mean age of the patients was 47.08 11.79. The tumor was frequently located centrally (61.5%), and the most common symptom was a palpable mass in the breast (92.3%). Four out of the 13 patients (32.5%) had axillary lymph node metastases. Hormone receptors were positive in five of seven patients (71.4%). Only one patient with advanced disease at the time of operation experienced distant metastases within 17 months after surgery. CONCLUSION: A papillary carcinoma is a rare type of breast cancer and has a favorable prognosis. The clinical outcome and histolgic characteristics were similar to those in other reports, but the mean age of the patients in this report was lower than that of Caucasian women.

Simple bone cyst (SBC) is very rare in adult ribs. The diagnosis basically relies on conventional radiography and occasionally on CT. There has been no earlier publication on PET/CT diagnosis of SBC. We report a case of adult costal SBC diagnosed by positive 18F-fluorodeoxyglucose (FDG) uptake. Histology showed the FDG uptake to be associated with reactive woven bone formation and nonspecific chronic inflammation. Correlation of PET, CT, plain radiography and sonography are also described.
