Meningioma is generally regarded as benign and extracranial metastasis of intracranial meningioma is rare. About 60 cases of distant metastasis of meningioma have now been reported. Angioblastic meningioma, although a rare type, shows rapid growth and sarcomatous change frequently, and has higher incidence of metastasis than other types of meningioma. The authors report a case of malignant angioblastic meningioma arisen in left olfactory groove with multiple metastasis to skeletal system. The available literature regarding these tumors is reviewed.

BACKGROUNDS/OBJECTOVES: Family has an impact on dietary intake of children as a proximal food environment and family structures are changing and becoming more diverse. This study was performed to identify the association between family structure and food group intake of children aged 3-18 years in Korea. SUBJECTS/METHODS: A total of 3,217 children with complete data on variables for household information, dietary intake and sampling weights were obtained from 2010-2011 Korea National Health and Nutrition Examination Survey. Children's family structure was classified into 3 groups (Living with both parents, Living with one parent and Living without parents). To evaluate children's food group intake, scores of individual food groups ('Grains', 'Meat, Fish, Eggs and Beans', 'Vegetables', 'Fruits' and 'Milk and Dairy products') was calculated from percent adherence to the recommended servings of the Korean Food Guidance System (KFGS). 'Food group mean score' was obtained by calculating the average of five food group scores. RESULTS: After adjusting for age, sex, number of family members, and household income, children living with both parents had higher scores in 'Fruits' (P < 0.01), 'Milk and Dairy products' (P < 0.05), and mean score of individual food group score (P < 0.001) compared to children living with one parent. Individual food group scores and mean scores of individual food group scores were associated with different socio-demographic factors in study children. Family structure was associated with 'Fruits,' 'Milk and Dairy products' score and mean scores of food group scores. CONCLUSIONS: These results suggested that different approach might be required to solve nutrition problem in children depending on their family structure and other socio-demographic factors.

Present study aimed to investigate the immunological activities of cell wall associated protein antigen solubilized with Triton X-100 (TSP) from Mycobacterium tuberculosis H37Rv and conducted on 43 patients with pulmonary tuberculosis (newly diagnosed, medicated within 12 months and chronic refractory patients) and 17 normal healthy controls. These immunological responses were compared with those induced by the PPD or 30 kDa antigen from M, tuberculosis H37Rv culture filtrates, identified as biologically important secreted proteins. Proliferative responses to mycobacterial antigens were compared in peripheral blood mononuclear cells (PBMC) of healthy subjects and pulmonary tuberculosis patients. Signiticant blastogenic responses to the TSP were observed in healthy tuberculin reactors, newly diagnosed and some of antituberculosis drug-medicated patients by H-thymidine incorporation assay. IL-12 p40 and IFN-r mRNA expressions to the TSP were markedly increased, whereas IL-10 and TNF-a mRNA expressions were decreased at a 5 day-stimulation by PBMC in healthy tuberculin reactors, newly diagnosed and medicated patients. However, patients with chronic refractory tuberculosis exhibited more depressed IL-12 p40 and IFN-r mRNA expressions to all of the antigens than another groups. Interestingly, very low IL-10 and TNF-a mRNA expressions cultured with the TSP were also shown. These data suggest that the TSP may be involved in the macrophage activation by induction of Th1 stimulatory signals, such as IL-12, and suppression of Th1 inhibitory cytokine, IL-10.

This study was conducted in order to investigate the association between picky eating behaviors of preschool children and growth outcomes. In this study, picky eating behaviors were defined as containing four constructs of 'eating a small amount (ES),' 'neophoic behavior (NB),' 'refusal of specific food groups (RF),' and 'preference for specific food-preparation methods (PP).' A 7-point scale was used for the multi-item questionnaire, which consisted of 21 items (three items for ES, two items for NB, nine items for RF, and seven items for PP), in order to evaluate picky eating behaviors of children. Subjects were recruited among visitors at a medical clinic in Seoul. A total of 150 self-administered survey responses from parents of preschool children were analyzed in order to investigate the association between picky eating behaviors of preschool children and growth outcomes. Height for age (HFA) and weight for height (WFH) z-scores were used for assessment of preschool children's growth. The prevalence of ES, NB, RF, and PP was 44%, 57%, 73%, and 53%, respectively. Children with ES had lower HFA (p < 0.05) and WFH (p < 0.0001) than those without ES, while children with NB, RF, or PP had HFA and WFH were similar to their counterparts. The mean HFA z-score of children with ES was less than 0 (p < 0.05) and the mean WFH z-scores of children with ES, NB, RF, or PP were less than 0 (p < 0.05). According to the study results, related growth outcome differed depending on constructs of picky eating behaviors. In particular, picky eating of ES showed a risk of faltering height growth in preschool children. Further comprehensive studies on the reason for ES and intervention approach is warranted.

We isolated Triton X-100 solubilized protein (TSP) antigen which may be preferentially associated with the cell wall of M. tuberculosis. In this study, the proliferative activities and cytokine mRNA expression patterns of the TSP antigen were investigated in peripheral blood mononuclear cells (PBMCs) and lymph node mononuclear cells (LNMCs) from 4 patients with tuberculous lymphadenitis. The results of the TSP antigen were compared with those of the PPD antigen, known as a major seretory protein antigen of M. tuberculosis. The peak proliferative response to the TSP by PBMCs was observed at 0.1 ug/ml, whereas that of LNMCs was at 1.0 ug/ml. All of the patients showed greater blastogenic responses for the PPD than those for the TSP. IFN-r, IL-2, and IL-2Ru mRNA production from PBMCs after stimulation with the TSP were greatly augmented after 48 hrs, whereas IL-4 and IL-10 mRNA were gradually suppressed. In addition, high levels of IL-12 p40 mRNA were detected by PBMCs to the TSP antigen at 3 hrs. Elevated IFN-r and IL-2 mRNA production were observed in freshly isolated LNMCs, whereas IL-4 mRNA production was undetectable in either freshly isolated or mycobacterial antigen-stimulated LNMCs. Furthermore, IL-10 mRNA expression from LNMCs was markedly increased by the PPD antigen, but it was considerably reduced by the TSP antigen after 18 hrs. These data suggest that the TSP antigen may be a strong inducer of cytokine mRNA such as IFN-r, IL-2, and IL-12 which are involved in Thl cell and macrophage activation, and inhibit IL-10 mRNA production in LNMCs. In conclusion, the TSP antigen can be used as a preferential Thl cell immunogen in tuberculous lymphadenitis.

It has been known that the immunological functions against cancer cells were diminished, and these phenomena result from the inhibition of cell-mediated immunity by substance(s) secreted from cancer cells. It was also reported that the immunological functions decreased in patients with stomach cancer, which is the most frequent cnacer in Korean. However, the nature and function of the inhibitory factor(s) orignated from stomach cancer have not been identified. To elucidate effects of immuological inhibitory factor(s) secreted from cancer cells, SNU-1 (stomach cancer) and SW480 P109/R3P2 (colon cancer) were used in this study. Jurkat T cell line, an acute T cell leukemia, was pre-incubated with fractionated cancer cell culture supernatant for 3 days, then was stimulated with PMA, PWVanti-CD28 mAb or PMA/ionomycin for 8 hrs respectively. Fraction of SNU-1 (3 - 10 kDa) and above 10 kDa of SW480 P109/R3P2 inhibited the expression of IFN-r mRNA when Jurkat T cell was stimulated with PMA. However, there were no difference in IL-2 and IL-4 gene expression response to either PMA/anti-CD28 mAb or PMA/ionomycin. These results show that cancer cells secret some inhibitory factor(s) acting on the immune response, especially IFN-r gene expression of the Jurkat T cells response to PMA. Therefore, it suggests that the inhibitory factor(s) secreted from cancer cells influences on. the PKC-dependent pathway related to the signal transduction by PMA.
