Neonatal alloimmune thrombocytopenia(NAIT) is a rare disease caused by maternal alloimmunization against fetal platelet surface antigen, which is mainly platelet specific alloantigen or human leukocyte antigen(HLA). During routine hemotology, we accidentally discovered thrombocytopenia in a female fullterm newborn admitted due to jaundice. We excluded NAIT due to human platelet alloantigen(HPA), because the HPA of the mother and baby were the same on PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). Mother's serum was tested for lyrnphocytotoxity against 36 donor lymphocytes, and anti-HLA A2, A24 and B58 were found. HLA typing of the father and baby revealed A2 antigen which was not present on the mothers lymphocytes. The patient received concentrated platelet and intravenous globulin. Her platelet count increased to 222,000/mm from 3,000/mm on the 11th day of life. We described a case of NAIT due to anti-HLA A2 antibody with a detailed clinical feature.

Quercetin is a natural flavonoid phytochemical that is extracted from various plants. Having an advantages due to its varied biological properties, such as anti-inflammatory, anti-viral, anti-oxidant, and anti-cancer effects, quercetin is used to treat many diseases. Recently, it has been reported that autophagy inhibition may play a key role in anti-cancer therapy. Therefore, in this study, we investigated the molecular mechanisms and anti-cancer effects of quercetin in human osteosarcoma cells via autophagy inhibition. We ascertained that quercetin inhibited cell proliferation and induced cell death, these process is demonstrated that apoptosis via the mitochondrial pathway and the caspase cascade. Quercetin also induced autophagy which was inhibited by 3-MA, autophagy inhibitor and the blockade of autophagy promoted the quercetin-induced apoptosis, confirming that autophagy is a pro-survival process. Thus, these findings demonstrate that quercetin is an effective anti-cancer agent, and the combination of quercetin and an autophagy inhibitor should enhance the effect of anti-cancer therapy.

BACKGROUND: The purpose of this study was to find the factors associated with becoming obese children during the past 2 years in 6th grade children of elementary school and then to evaluate the high risk groups for childhood obesity. METHODS: The 738 children from May to June, 2001 in 6th grade of 5 elementary schools in Busan were the subjects of this study. The children's height and weight in 4th grade and 6th grade were obtained from school health records. We calculated the body mass index in 4th and 6th grades and classified into 3 weight groups (normal, at risk for obesity, and obese) according to the age and sex-specific BMI established by the Korean Academy of Pediatrics. If children's weight group in 4th grade was changed to heavier weight group in 6th grade, we defined it as increased group. Otherwise, we defined it as non-increased group. The association between the increase in weight group and parental and children's characteristics were analyzed by x2-test, x2-test for the trend, t-test, ANOVA and multiple logistic regression. RESULTS: Among the total, 3.3% of children with normal weight and 16.9% of children at the risk for obesity in 4th grade were transformed to increased group in 6th grade, respectively (P<0.001). Children who had excessive appetite (P<0.001), watched TV greater than or equal to 2 hours per day (P=0.004) or had an obese father (P=0.044) were more likely to become increased group. After adjusting for father's obesity, appetite and TV watching time in children, the odds ratio of transforming to increased group after 2 years in children at risk for obesity or in obese child in 4th grade was 2.5 (95% CI: 1.09~5.55) compared to children with normal weight. Children having excessive appetite were 3.2 times (95% CI: 1.42~7.01) more likely to become the increased group after adjusting for father's obesity, TV watching time and weight in 4th grade. Children watching TV greater than or equal to 2 hours/day was 2.8 times (95% CI: 1.27~6.18) more likely to become increased group after adjusting for father's obesity, appetite and weight in 4th grade. CONCLUSION: The risk of becoming obese was higher in children at risk for obesity or obese children in those with excessive appetite or those who have watched TV> or =2 hours/day for the past two years. These findings suggest promotion of educational plan to prevent childhood obesity.

Shikonin, a major ingredient in the traditional Chinese herb Lithospermumerythrorhizon, exhibits multiple biological functions including antimicrobial, anti-inflammatory, and antitumor effects. It has recently been reported that shikonin displays antitumor properties in many cancers. This study was aimed to investigate whether shikonin could inhibit oral squamous carcinoma cell (OSCC) growth via mechanisms of apoptosis and cell cycle arrest. The effects of shikonin on the viability and growth of OSCC cell line, SCC25 cells were assessed by MTT assay and clonogenic assays, respectively. Hoechst staining and DNA electrophoresis indicated that the shikonin-treated SCC25 cells were undergoing apoptosis. Western blotting, immunocytochemistry, confocal microscopy, flow cytometry, MMP activity, and proteasome activity also supported the finding that shikonin induces apoptosis. Shikonin treatment of SCC25 cells resulted in a time- and dose-dependent decrease in cell viability, inhibition of cell growth, and increase in apoptotic cell death. The treated SCC25 cells showed several lines of apoptotic manifestation as follows: nuclear condensation; DNA fragmentation; reduced MMP and proteasome activity; decrease in DNA contents; release of cytochrome c into cytosol; translocation of AIF and DFF40 (CAD) onto the nuclei; a significant shift in Bax/Bcl-2 ratio; and activation of caspase-9, -7, -6, and -3, as well as PARP, lamin A/C, and DFF45 (ICAD). Shikonin treatment also resulted in down-regulation of the G1 cell cycle-related proteins and up-regulation of p27(KIP1). Taken together, our present findings demonstrate that shikonin strongly inhibits cell proliferation by modulating the expression of the G1 cell cycle-related proteins, and that it induces apoptosis via the proteasome, mitochondria, and caspase cascades in SCC25 cells.

OBJECTIVES: The purpose of this study was to evaluate the predictors of metabolic syndrome in shipyard workers in the Southwestern part of South Korea and determine its prevalence. METHODS: The study subjects were composed of 1,198 medical check-up examinees, age 37 to 58 years who were examined in a general hospital from July, 2007 to August, 2008. Information about age, smoking, drinking and exercise was based on data from self-administered questionnaires. We collected job factors, education level and marital status from company personnel data and the indices of metabolic syndrome from the medical check-up. RESULTS: The prevalence of metabolic syndrome among the 1,198 shipyard workers was 15.0%. The prevalence of the components of metabolic syndrome was as follows: 26.9% for central obesity, 31.7% for hypertension, 32.2% for hypertriglyceridemia, 19.2% for low HDL-cholesterolemia and 5.2% for hyperglycemia. Adjusted odds ratio for metabolic syndrome was significantly decreased in productive workers (OR: 0.500, 95% CI: 0.327-0.764). Furthermore, factors such as age, smoking, drinking, exercise, work duration and job type were significantly associated with metabolic syndrome. CONCLUSIONS: Our findings suggest that even though shipyard workers work for the same employer, the prevalence of metabolic syndrome varies to job type, shift work and work duration. Therefore, general metabolic syndrome management programs for shipyard workers should be designed and tailor-made for specified job characteristics to prevent cardiovascular disease more effectively. Also, thorough control and management of the tailor made metabolic syndrome management programs is needed in the early stages of metabolic syndrome for good health outcomes.

Periodontal inflammation increases the risk of tooth loss, particularly in cases where there is an associated loss of alveolar bone and periodontal ligament (PDL). Histological and morphometric evaluation of periodontal inflammation is difficult. Especially, the lengths of the periodontal ligament and interdental alveolar bone space have not been quantified. A quantitative imaging procedure applicable to an animal model would be an important clinical study. The purpose of this study was to quantify the loss of alveolar bone and periodontal ligament by evaluation with micro-computed tomography (micro-CT). Another purpose was to investigate differences in infections with systemic E. coli LPS and TNF-alpha on E. coli lipopolysaccharide (LPS) in loss of alveolar bone and periodontal ligament model on mice. This study showed that linear measurements of alveolar bone loss were represented with an increasing trend of the periodontal ligament length and interdental alveolar process space. The effects of systemic E. coli LPS and TNF-alpha on an E. coli LPS-induced periodontitis mice model were investigated in this research. Loss of periodontal ligament and alveolar bone were evaluated by micro-computed tomography (micro-CT) and calculated by the two- and three dimensional microstructure morphometric parameters. Also, there was a significantly increasing trend of the interdental alveolar process space in E. coli LPS and TNF-alpha on E. coli LPS compared to PBS. And E. coli LPS and TNF-alpha on E. coli LPS had a slightly increasing trend of the periodontal ligament length. The increasing trend of TNF-alpha on the LPS-induced mice model in this experiment supports the previous studies on the contribution of periodontal diseases in the pathogenesis of systemic diseases. Also, our findings offer a unique model for the study of the role of LPS-induced TNF-alpha in systemic and chronic local inflammatory processes and inflammatory diseases. In this study, we performed rapidly quantification of the periodontal inflammatory processes and periodontal bone loss using micro-computed tomography (micro-CT) in mice.
