본 연구에서는 만성질환의 주요 위험인자인 비만을 예방하기 위한 식품소재로서 3T3-L1세포를 이용하여 탈피한 도토리의 항비만 효과를 알아보고자 하였다. 3T3-L1 세포에서 생존율(MTT assay)을 측정한 결과, AE와 AW 시료 모두 $500{\mu}g/mL$ 농도에서는 다소 생존율의 감소를 보여, $300{\mu}g/mL$를 최종 농도로 정하였다. 3T3-L1 세포의 지질축적 억제 효과를 측정한 결과, 농도 $100{\mu}g/mL$로 처리하였을 때 두 시료 모두 지질축적량의 증가를 보였으나, $200{\mu}g/mL$ 처리농도에서 AE 시료는 82%로, AW 시료는 74%로 감소되다가 $300 {\mu}g/mL$ 농도에서는 두 시료 모두 약 53% 수준까지 지질축적이 억제되었다. 3T3-L1 세포에서 중성지방 억제 효과를 확인한 결과, AE 시료의 경우 $200{\mu}g/mL$ 농도에서 11%의 감소율, $300{\mu}g/mL$ 농도에서 42% 수준의 감소율을 보였다. AW 시료도 $200{\mu}g/mL$ 농도에서 5%의 감소율과 $300{\mu}g/mL$에서 41%의 감소율을 보였다. 3T3-L1 세포의 ROS 생성량을 측정한 결과, 시료 농도 $200{\mu}g/mL$에서 AE는 42%, AW는 33%로 $300{\mu}g/mL$에서는 AE는 58%, AW는 52%로 ROS 생성량의 억제를 보였다. 3T3-L1 세포에서 mRNA 발현에 미치는 영향을 대조군과 비교하였을 때 두 시료(AE와 AW) 모두 $300{\mu}g/mL$ 농도에서 $PPAR-{\gamma}$은 54%와 38%, aP2는 40%와 18% 수준의 발현을 억제시키는 것으로 나타났다. 이상의 결과로 볼 때 탈피한 도토리는 3T3-L1 세포의 분화를 억제함으로써 새로운 항비만 소재로의 가능성이 있는 것으로 판단된다. This study aimed to investigate the suppressive effect of acorn extracts, by evaluating 70% ethanol extract (AE) and hot water extract (AW) using 3T3-L1 preadipocytes. We applied various levels (0, 100, 200, 300 and $500 {\mu}g/mL$) of AE and AW to 3T3-L1 preadipocytes. The cell viability of the 3T3-L1 preadipocytes was not affected by up $300 {\mu}g/mL$ of extracts, but was suppressed by level $500{\mu}g/mL$ of both AE and AW by 20% and 9% respectively. The accumulation of lipid droplets in differentiated 3T3-L1 preadipocytes was dose-dependently suppressed by AE and AW. Especially, at high concentrations ($300{\mu}g/mL$), AE (42%) was more effective than AW (41%). Reactive oxygen species (ROS) was also dose-dependently suppressed by treatment with AE (58%) and AW (52%). With regard to the mRNA related to differentiated 3T3-L1 preadipocytes, $PPAR-{\gamma}$ and aP2 were suppressed by treatment with AE (54 and 40%) and AW (38 and 18%). From our results, acorn extract (AE) has more suppressive effects than AW in differentiated 3T3-L1 preadipocytes. We therefore concluded that acorn has suppressive effects against obesity in differentiated 3T3-L1 cells due to antioxidation.

Objectives : Vulnerability marker in biological relatives of schizophrenia may be very useful in identifying the propensity for the development of schizophrenia. This study suggests that the relatives at risk for genetically developing schizophrenia have impairments in several domains of cognition, social function and affective function as a vulnerability marker. Methods : A neurocognitive function test, a social function test and an affective function test were administered to fifteen healthy relatives from families with two or more patients with schizophrenia (geneticallly high risk subjects). Fifteen healthy controls matched for age and gender were recruited in this study. Results : Compared to the control subject, the genetic high risk subjects performed significantly more poorly in the selective attention and recall memory of neurocognitive function. The high dsk subjects also had lower scores in independence-performance and independence-competence of the social function test and emotion control of the affective function test. Conclusion : Selective attention, recall memory, independence-performance, independence-competence and emotion control ability may be a valuable marker for genetic study of schizophrenia.

Objectives : The aims of this study were to identify the intake and following process for subjects at high risk of transition to schizophrenia and to examine the neurocognitive, social, and emotional functions of the subjects compared with healthy controls. Methods : Symptomatic individuals judged at high risk for schizophrenia ('clinical high risk') within Youth Clinic were assessed and followed up. They performed a neurocognitive function test, a social function test and an affective function test. Twenty healthy controls were recruited in this study. Results : Among eighty-two subjects contacted through the Youth clinic, sixteen subjects were judged as the clinical high risk group. Fourteen subjects among the clinical high risk group showed deficits in several domains of neurocognitive functions, such as visual recall memory, verbal short term memory and executive function. Social and affective functions are also impaired in the Cli-nical high risk group compared with healthy controls. Two of 15 subjects (13%) developed a psychotic disorder within 6 months. Conclusion : This study illustrates the state of follow-up study for a clinical high risk group. Despite low numbers and short durations, some impairment of several functions in the clinical high risk group suggests possible predictors of psychosis.

Anti-Allergic Effect of Oroxylin A from Oroxylum indicum Using in vivo and in vitro Experiments

( Ae Yeon Lee ),( Saeromi Kang ),( Soo Jin Park ),( Jin Huang ),( Dong Soon Im ) 한국응용약물학회 2016 Biomolecules & Therapeutics(구 응용약물학회지) Vol.24 No.3

Oroxylum indicum has long been used in Asian traditional medicine to prevent and treat respiratory diseases, diabetes, diarrhea and other conditions. Oroxylin A is a flavone that is present in Oroxylum indicum and in Scutellaria baicalensis. Because the root extracts of both plants have been shown to have anti-allergic effects, the authors investigated whether oroxylin A is likely to have beneficial effects on allergic asthma using female Balb/c mice and rat RBL-2H3 mast cells. Antigen-induced degranulation was measured in vitro by measuring b-hexosaminidase activity. A murine ovalbumin-induced allergic asthma model was used to test the in vivo efficacy of oroxylin A. Sensitization and challenge of ovalbumin induced allergic asthma responses, the accumulations of eosinophils and Th2 cytokine levels in bronchoalveolar lavage fluid and lung tissues. Oroxylin A administration decreased numbers of inflammatory cells, especially eosinophils, and reduced the expression and secretion of Th2 cytokines, including IL-4 and IL-13, in lung tissues and bronchoalveolar lavage fluid. Histologic studies showed oroxylin A reduced inflammatory signs and mucin production in lungs. These findings provide evidence that oroxylin A has potential use as an anti-allergic therapeutic.

Proteomic analysis of pulmonary sclerosing hemangioma

Jin, Lian-Jin,Shin, Bong Kyung,Jung, Woon Yong,Lee, Hyun-Juu,Cho, Su Jin,Han, Joung-Ho,Ha, Seong-Yeon,Kim, Ae-Ree,Sik Kim, Young,Sun Kim, In,Uhm, Chang-Sub,Kim, Han Kyeom WILEY-VCH 2006 Proteomics Vol. No.

<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>
