The Photocatalytic decolorization and degradation of commercial dyes were studied using a batch reactor. Degussa P25 titanium dioxide and H_2O_2 were used as the photocatalyst and proved to be effective for dyes degradation when they were irradiated with UV light. The light source was a 20W low pressure mercury lamp. Three different kinds of dyes, such as direct dye(congo red), acid dye(acid black) and disperse dye(disperse blue) were tested. Extending the UV only treatment up to 120min, direct dye was decolorized to 60% and degraded to 30% as COD. On the other side, acid and disperse dyes were eliminated less than 10% as color and COD. But, color and COD were eliminated about 90% for all of the three dyes by UV/H_2O_2 system. And then the most effective decolorization was done for direct dye with 96% removal efficiency by UV/TiO_2 system at 120min 500mg/L of TiO_2.

<P>Sclerosing hemangioma (SH) is a rare benign pulmonary tumor derived from the primitive respiratory epithelium. However, the pathogenesis of SH has not yet been clear. Surfactant protein, thyroid transcription factor-1, epithelial membrane antigen, cytokeratin, and vimentin have been identified in SH by immunohistochemistry and electron microscopy. To identify proteins specifically regulated in SH, 2-D PAGE was performed using SH and paired normal tissues. Ten selected differentially expressed protein spots were identified by PMF, MALDI-TOF-MS, and database searching. Apolipoprotein A-1, antizyme inhibitor, heat shock 27-kDa protein 1, and antioxidant proteins, such as peroxiredoxin II (Prx II) and GST, were identified among the down-regulated proteins in SH. Western blot and immunohistochemistry confirmed reduced expressions of Prx II and GST in SH versus normal lung tissue. This study is the first report on the reduced expressions of Prx II and GST in SH.</P>

<P>Postinjection transmission positron emission tomography (PET) may be useful for shortening the total scan time. In this study, the effect of post-transmission scanning was assessed using PET on a phantom (NU4) and actual rat brain.</P>

Henoch-Schonlein purpura (HSP) is a vasculitis of the small vessels of the skin, joints, gastrointestinal tract, and kidneys characterized by immunoglobulin A deposits in the involved organs. HSP is typified by the classic tetrad of purpura, arthralgia, abdominal pain, and renal involvement. It is common in childhood, but may also occur in adults and can be accompanied by severe complications. Gastrointestinal symptoms occur in up to 85% of patients,and gastrointestinal involvement can manifest as severe problems including intussusception, obstruction, and perforation. The disease course is often self-limited, but severe manifestations occasionally require surgical intervention. We report the case of a 24-year-old man with HSP who presented with abdominal pain and vomiting. Computerized tomography revealed thickening of the ileal wall and multifocal disrupted prominent mucosal enhancement. These findings suggested hemorrhagic enteritis and mucosal necrosis. After treatment with high dose corticosteroids, the lesion improved and surgical intervention was avoided. Our experience suggests that corticosteroid therapy may help in controlling HSP with suspicious small bowel necrosis. (Intest Res 2011;9:148-152)
Haplotype Analysis of Prostate Stem Cell Antigen and Association With Prostate Cancer Risk
Joung, Jae Young,Lee, Yeon-Su,Park, Sohee,Yoon, Hyekyoung,Lee, Sang Jin,Park, Weon Seo,Seo, Ho Kyung,Chung, Jinsoo,Kim, Sook-young,Hong, Seung-Hyun,Kim, Jeong Seon,Lee, Kang Hyun Elsevier 2011 The Journal of urology Vol.185 No.6
<P><B>Purpose</B></P> <P>Prostate stem cell antigen has become a promising target as a potential biomarker for prostate cancer, but to our knowledge there are no reports of a genetic variation of the PSCA gene associated with prostate cancer risk. We determined the potential association between specific variations of the PSCA gene and prostate cancer in Korean men.</P> <P><B>Materials and Methods</B></P> <P>In this hospital based, case-control study 194 patients newly diagnosed with histologically confirmed prostate cancer were enrolled. Visitors for cancer screening served as healthy controls. We genotyped 12 PSCA gene single nucleotide polymorphisms in 194 cases and 169 healthy controls.</P> <P><B>Results</B></P> <P>Men with the rs1045531 AA genotype were at higher risk for prostate cancer than those with the CC genotype. Individuals with the CCCAGGTACGG haplotype were at significantly increased risk for prostate cancer. When considering clinical factors, rs3736001, which is a nonsynonymous cDNA single nucleotide polymorphism (Glu39Lys), showed an association with prostate specific antigen 10 ng/ml or greater and prostate cancer risk.</P> <P><B>Conclusions</B></P> <P>Men with the rs1045531 AA genotype of PSCA were at higher risk for prostate cancer. On haplotype analysis CCCAGGTACGG and CGA haplotype carriers showed a significant association with prostate cancer risk. To our knowledge this is the first report of PSCA genetic variation associated with prostate cancer risk.</P>
서울시내 일부 저소득층 비급식국민학교 아동의 식생태에 관한 연구
모수미,정상진,최선혜,이수정 한국식생활문화학회 1991 韓國食生活文化學會誌 Vol.6 No.4
A study of eating behavior was conducted among 274 children of Nan Hyang elementary school, located in low income area of Seoul, where a school lunch program is not operated. During weekdays, 19.6% of children ate breakfast and 18.4% ate supper alone or with their siblings. The school provided boxed lunches for 10.5% of the children with governmental funds, who were chosen by the school based on their household income. But the percentage of the children skipping breakfast was 14.6%, lunch 10.3% and supper 8.0%. The results of nutritional analysis of the children who had three meals a day and those of children skipped one of the regular meals were compared. The group who had three meals consumed more nutrients except vitamin C than the group skipped meal (p<0.01). Most common meal pattern was consisted of cooked rice, Kimchi and side dishes. When the children didn't have afternoon classes, 10.0% of the children ate Ramen only at home without any side dishes. Among the protein sources, the beans and bean products were the most common items. When we studied the three different lunches such as A) the boxed lunches provided by school, B) the boxed lunches from home and C) the lunches ate at home, the A) lunches provided the most common items. When we studied the three different lunches such as A) the boxed lunches provided by school, B) the boxed lunches from home and C) the lunches ate at home, the A) lunches provided the milk products, fruits, ice cakes…etc. Their favorite foods were fruits, yoghurt, Chinese black noodle, and sweet potatoes whereas being not prefered foods, were aromatic vegetables. It seemed that the increasing rate of working mothers and the overflooding of instant foods have caused to neglect children's meal management. To solve these problems, nutrition education and extend of school lunch programs should be emphasized.
