염증성 장 질환에 일반적으로 사용되는 설파살라진은 고용량 및 장기 섭취 후 다양한 부작용이 있다. 본 연구에서는 TNBS로 유발된 마우스 대장염 모델에서 설파살라진, 육계와 시호 복합추출물의 항염증 및 세포 자멸 개선효과를 확인하고자 하였다. 실험은 정상군, TNBS 대조군, Sulfasalazine (30 mg/kg)군, Sulfasalazine (60 mg/kg)군, Sulfasalazine (30 mg/kg)+육계 및 시호 혼합 (30 mg/kg)군, 총 5개의 군으로 나누었으며, 7일간 경구투여 하였다. 염증 및 세포 자멸 단백질은 western blot을 통해 발현량을 확인하였다. SCB 투여는 염증 단백질 및 세포 자멸과 관련된 단백질의 억제에 유의한 효과를 나타냈다. 이러한 결과로 보아 설파살라진, 육계와 시호 복합 추출물은 염증과 세포 자멸의 억제를 통해 염증성 장 질환을 개선시킬 수 있으며, 염증성 장 질환의 치료 대안 가능 물질로 사료되는 바이다. Inflammatory bowel disease (IBD) is including Crohn`s disease and ulcerative colitis. Sulfasalazine commonly used in IBD, possibly has various side effects after high dosage and long term intake. The present study aimed to investigate the sulfasalazine and combination with herbal medicine on 2,4,6- trinitrobenzene sulfonic acid (TNBS)-induced in mice model. TNBS-induced mice were injected through a flexible catheter 4 cm in length 1.6 mg TNBS. Animals were divided into five groups (n=12): Normal group, TNBS control group, Sulfasalazine (30 mg/kg) group, Sulfasalazine (60 mg/kg) group, Sulfasalazine (30 mg/kg)+Cinnamomi cortex and Bupleuri radix mixture (30 mg/kg) (SCB) group. Administration groups were fed extract during 7 days. The inflammatory, and apoptotic protein levels were determined using western blotting. SCB treatment showed an outstanding effectiveness in counteracting the IBD, as assessed by reduction of body weight loss, down-regulation of proinflammatory proteins and cytokines, and by inhibition of proteins related to apoptosis. This is the first report that sulfasalazine and Cinnamomi cortex plus Bupleuri radix mixture improve the severity of experimental IBD through the inhibition of both inflammation and apoptosis. We confirm that the SCB treatment instead of sulfasalazine alone may be promising as an alternative therapeutic plan against IBD, without any evidence of adverse effects.

Objectives : Obesity is caused by the excess accumulation of fat in the body due to energy imbalance, and it causes various diseases. The aim of this study was to investigate an anti-obesity efficacy and an antioxidant activity of water from herbal mixture extract (SM17). Methods : The antioxidant activities were evaluated through radical scavenging assays using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals. To evaluated anti-obesity effect of SM17, we used a high fat diet fed mouse model. The SM17 (150 mg/kg body weight/day, p.o.) was treated every day for 6 weeks to C57BL/6 mice. Body weight and food intake were measured every day. The changes of reactive oxygen species (ROS), alanine aminotransferanse (ALT), aspartate aminotransferase (AST), triglycerids (TG) and total cholesterol (TC) in serum were analyzed after experiment. Also, expression of lipid metabolism related proteins were investigated by western blot analysis. Results : It was effective in antioxidant measurements, SM17 administration inhibited the biomarkers of lipid metaboism in serum and tissues. The administration of SM17 showed a significant reduction of body and tissue weight. Morever, it decreased ROS, ALT, AST, TG and TC in serum, compared with those of the obese mice. Adipogenesis-related protein expressions increased in obese mice compared to normal mice. However, SM17 group exhibited the down-expression of these proteins. Conclusion : A SM17 aqueous extract has a great effect on the stimulation (AMPK) activation, and may have a benefit to reduce a fatty acid metabolism through inhibition of lipid accumulation.

Objectives : This study aimed to effects antioxidant activity of citrus peel extract (CPE) and effect on its glucose metabolism in L6 rat skeletal muscle cells. Methods : Antioxidative activities were evaluated by using 10 kinds of natural materials, and total polyphenol and flavonoid contents were examined. The L6 muscle cells toxicity of CPE was examined by MTT assay. Expression of glucose-related genes in L6 muscle cells by CPE treatment was analyzed by real-time PCR and western blotting. Results : The IC₅₀ values of DPPH and ABTS free radical scavenging activity of CPE were (15.47 ± 0.26 ㎍/㎖ and 12.07 ± 1.23 ㎍/㎖, respectively), effectively clearing DPPH and ABTS. CPE showed total polyphenol and flavonoid contents (20.30 ± 0.38 and 64.20 ± 0.52, respectively). The selected CPE were used in experiments using an effective concentration that is not toxic in L6 muscle cells. We investigated insulin receptor substrate-1 (IRS-1), phosphatidylinositol 3-kinase regulatory (PI3KR), Akt, and glucose transporter 4 (GLUT4). mRNA analysis by realtime PCR showed no significant difference, but CPE-treated cells showed a tendency to increase in concentrationdependent manner. However, analysis of protein expression of Akt and GLUT4 by western blotting showed that CPE treatment significantly increased concentration dependent (p<0.001). Conclusions : As a result, citrus peel extract with high antioxidant activity regulates glucose metabolism in L6 muscle cells. Therefore, CPE can be a potential treatment for the treatment of diabetes.

조정민,류병곤,박성우,김경조,백기태,Cho, Jung-Min,Ryu, Byung-Gon,Park, Sung-Woo,Kim, Kyeong-Jo,Baek, Ki-Tae 한국지하수토양환경학회 2009 지하수토양환경 Vol.14 No.1

Zn, Ni 및 불소로 복합 오염된 토양의 정화를 위해서 동전기 정화(Electrokinetic remediation)기술을 적용하였다. 토양에서 탈착된 불소는 음이온 형태이고, Zn, Ni은 양이온으로 존재하기 때문에 간극수가 이동하는 전기삼투(electro-osmosis)와 이온이 이동하는 전기이동(electro-migration)의 두 가지 기작에 의해 제거되는 경향이 달랐다. 불소는 알칼리 조건에서 토양으로부터의 탈착이 증가하고, Zn과 Ni은 산성조건에서 탈착이 증가된다. 두 가지 탈착 특성이 다른 오염물질을 순차적 pH조절을 통해 효과적으로 제어할 수 있었다. 정전압 하에서의 영향을 평가하기 위하여 2V/cm를 적용하여으며, 2주간의 실험을 통해 Zn은 20.5%, Ni은 2.5%, 불소는 57.4% 제거되었다. Zn과 Ni의 제거율은 낮았으나 토양 ph조절을 통해 이동 가능함을 확인하였다. 토양 pH조절을 통하여 특성이 다른 복합오염물질을 동전기 정화 기술로 제거할 수 있을 것으로 사료된다. The feasibility of electrokinetic remediation was investigated in the laboratory to treat contaminated soil with Zn, Ni and F. Electro-migration and electro-osmosis are the major removal mechanisms because fluorines desorbed from soil exist as an anionic form in soil pores, and Zn and Ni exist as a cationic form. Desorption of fluorine was enhanced under the alkaline condition, but that of Zn and Ni increased under the acidic condition. Sequential pH control was effective to control the mixed wastes from contaminated soil. 2 V/cm was applied to reactor to evaluate the effect of constant voltage gradient, after two weeks, the removal efficiency of Zn, Ni and F was 20.5%, 2.5% and 57.4%, respectively. Even though the removal of Zn and Ni was very low, the pH control enhanced transport of Zn and Ni significantly. As a result, sequential pH control is a effective method to remediate mixed waste-contaminated soil.
