Bechet's disease(BD) is a chronic inflammatoroy condition involving several organs inclu-ding gastrointestinal tract. Gastrointestinal tracts involvement in BD has been identified throughout the entire alimentary tract and commonly accompanies ulcerative lesions in the small and large bowel. It is debatable whether BD could be included among seronegative spondyloarthropathy (SPA).SPA usually occurs without overt sign of intestinal inflammation, but significant number of patients have asymptomatic intestinal inflammation, usually affecting ileum. Since most patients with SPA in-cluding BD are treated with NSAIDS. However, NSAID may play a role in aggravation or provo-cation of intestinal inflammation. Special attention to asymptomatic intestinal inflammation is needed, especially when NSAIDs are used for management of arthritic symptom in SpA. We experienced a case of BD which was complicated by a massive small bowel bleeding precipitated by NSAID use. 저자들은 베체트병 환자에서 비스테로이드성 소염진통제 사용 후 발생한 대량 소장 출혈의 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Obesity can be defined as a disorder of lipid metabolism and the control of this process is regulated by enzymes involved in lipid metabolic pathway. Obesity is also characterized increases in the number and size of adipocyte differentiated from fibroblastic pre-adipocytes in adipose tissue. The aim of this study was to screen ethanol extracts of 21 fruits and vegetables cultivated in Republic of Korea for identifying natural sources of lipase inhibitor and to investigate the effects of several extracts resulting in suppression of triglyceride (TG) accumulation in 3T3-L1 cells. Among the tested extracts, Diospyros kaki L. showed the highest contents of total sugar and the content of total phenolic compounds was detected 17 species while there was not detected in Ixeris dentate root and Allium fistulosum C. etc. We were screened 26 extracts of fruits and vegetables for pancreatic lipase inhibitory activity compared with orlistat. The strongest lipase inhibitory activities were shown by extract of Allium sativum L. stem, Allium sativum L. bulb, Apteryx australis, Diospyros kaki L. Malus Pumila, Perilla frutescens and Prunus mume regardless of concentrations treated. Eight extracts including Brassica juncea var. integrilolia had no effect on lipase inhibition. During the differentiation of 3T3-L1 preadipocyte to mature adipocyte, the cells were treated with carrier or 7 extracts(1, 5 and 10 ㎍/ml), which was shown to highest lipase inhibitory effects. We were quantified lipid contents secreted mature adipocytes and stained with Oil Red O. All cells treated with the Apteryx australis and Prunus mume significantly decreased TG contents than the control. These findings suggested that the screened fruit and vegetable could be a promising source as the effective and safe lipase inhibitors for isolating bioactive ingredients and developing functional foods.

Macroporous titania crystallites were synthesized using an emulsion-assisted self-assembly method to prepare a photocatalyst for the decomposition of organic dyes such as methylene blue. The porous structure was prepared using polymeric particles as sacrificial templates, which were synthesized by large-scale dispersion polymerization. An in-depth study was performed to characterize the photocatalytic performance of the porous spherical titania particles by evaluating the rate constants of the decomposition reactions. Factors affecting the reaction rates were studied by controlling the size of macropores, the average diameter of the porous particles, the amount of photocatalysts and methylene blue in reaction mixture, and the power of the UV light sources. Enhanced photocatalytic performances were also observed for porous particles with hollow microstructure obtained using a rotating cylinder system, or bimodal porous particles.

Purpose: Purposes of this study were to understand the current trends on complementary therapy in relieving chemotherapy-induced nausea and vomiting and to suggest the future research direction. Method: Subjects were selected on CINAHL, MEDLINE, Korean Academy Data Base from 1980 to 2001 which used nausea, vomiting, chemotherapy and complementary therapy as key words in experimental studies. Eight korean articles and twenty-one international articles were analyzed in terms of general characteristics, research methods, and types of complementary therapy. Data were analyzed by using descriptive statistical methods. Result: Since 2000, researchers have more actively used complementary therapy. In subject characteristics, mean age was 35.5 years old, 45% of the researchers were performed with high level of incidence of chemotherapy induced vomiting, 14% of them set limit of consecutive cycle during research, and 65% of them did not comment the selecting criteria of sample. About 60% of them were designed post-test only control group: 35% used INV by Rhodes, 31% used Likert scale, and 24% used VAS for dependent variable. Muscle relaxation therapy was mostly applied for relief of nausea and vomiting. Conclusion: Further studies will be needed to control extrinsic variables affecting nausea and vomiting in research design and to accumulate evidence with studies applying various complementary therapies.

Utilizing the electrospinning technique nanofiber-based biodegradable scaffolds made of PLGA was suggested. Under various conditions, their diameters and porosity as well as mechanical strength were evaluated. In addition to those, cell(chondrocyte) proliferation and formation of extracelluar matrices were also investigated along with the conventional membrane type PLGA scaffolds for the potential use in tissue engineering. As conclusions, this type of scaffold showed a potential of application to tissue engineering in view of mechanical stability as well as cellular responses.

Objective: The favored method of preserving fertility in young female cancer survivors is cryopreservation and autotransplantation of ovarian tissue. Reducing hypoxia until angiogenesis takes place is essential for the survival of transplanted ovarian tissue. The aim of this study was to investigate the role of angiopoietin-1 (Angpt-1), angiopoietin-2 (Angpt-2), and vascular endothelial growth factor (VEGF) in ovarian tissue grafts that were cryopreserved using two methods. Methods: Ovarian tissues harvested from ICR mice were divided into three groups: group I (control), no cryopreservation; group II, vitrification in EFS (ethylene-glycol, ficoll, and sucrose solution)-40; and group III, slow freezing in dimethyl sulfoxide. We extracted mRNA for VEGF, Angpt-1, and Angpt-2 from ovarian tissue 1 week following cryopreservation and again 2 weeks after autotransplantation. We used reverse transcriptase-polymerase chain reaction to quantify the levels of VEGF, Angpt-1, and Angpt-2 in the tissue. Results: Angpt-1 and Angpt-2 expression decreased after cryopreservation in groups II and III. After autotransplantation, Angpt-1 and Angpt-2 expression in ovarian tissue showed different trends. Angpt-1 expression in groups II and III was lower than in group I, but Angpt-2 in groups II and III showed no significant difference from group I. The vitrified ovarian tissues had higher expression of VEGF and Angpt-2 than the slow-frozen ovarian tissues, but the difference was not statistically significant. Conclusion: Our results indicate that Angpt-2 may play an important role in ovarian tissue transplantation after cryopreservation although further studies are needed to understand its exact function.
