Etiological studies of diabetes and its complications showed that oxidative stress might play a major role, Therefore, many efforts have been tried to regulate free oxygen radicals for treating diabetes and its complications. Mori Fructus extract has been known to be effective for the antidiabetic, antihyperlipidemic and antiobesitic prescription, and composed of four crude herbs, The aim of this study was to investigate the effect of Mori Fructus extract in male ob/ob mouse with severe obesity, hyperinsulinemia, hyperglycemia, hyperlipidemia. Mice were grouped and treated for 5 weeks as follows. Both the lean (C57BL/6J black mice) and diabetic (ob/ob mice) control groups received standard chow. The experimental groups were fed with a diet of chow supplemented with 7.5, 15 and 30 mg Mori Fructus extract per 1 kg of body weight for 14 days. The effects of Mori Fructus extract on the ob/ob mice were observed by measuring the serum levels of glucose, insulin, lipid components, and the kidney levels of reactive oxygen species (ROS), MDA+HAE, GSH and also the enzyme activities involved in polyol pathway. Western blotting was performed using anti-AGE, anti-RAGE respectively. Mori Fructus extract lowered the levels of serum glucose and insulin in a dose dependent manner. Total cholesterol, triglyceride and free fatty acid levels were decreased, while the HDL-cholesterol level was increased, in Mori Fructus extract treated groups. Renal aldose reductase and sorbitol dehydrogenase activities were increased in the ob/ob mice, whereas those were inhibited in the Mori Fructus extract-administered groups. Mori Fructus extract inhibited the generation of ROS in the kidney. MDA+HAE level was increased and the GSH level was decreased in the ob/ob mice, whereas those were improved in the Mori Fructus extract-administered groups. Mori Fructus extract inhibited the expression of AGE, RAGE in the ob/ob mice. The results suggested that Mori Fructus exerted the antidiabetic and antihyperlipidemic activities by regulating the activities of polyol pathway enzymes, scavenging the ROS, decreasing the MDA+HAE level, increasing the GSH level and inhibiting the expression of AGE, RAGE in the ob/ob mice.

Objectives : Although the pharmacological effects of anti-inflammatory and antioxidant action of Atractylodes macrocephala Koidzumi water extract (AM) have been proven from many studies, reports on the antioxidant effect of AM on ulcerative colitis (UC) are scarce. Therefore, we aimed at evaluating the anti-oxidant effect of AM on the DSS-induced UC model. Methods : To induce ulcerative colitis, 8-week-old male Balb/c mice received 5% DSS in drinking water for 1 week. After 1 week of adaptation, mice were divided into four groups (n=8 each) for use as normal (Normal), DSS Control (Control), DSS + AM 100 mg/kg (AM100)-treatment, DSS + AM 200 mg/kg (AM200)-treatment. After 1 week of the experiment, the animals were sacrificed, and the extracted colon tissue was analyzed for protein through western blot. Results : As a result of confirming the macroscopic changes in colon tissues to confirm the therapeutic effects of AM, the decrease in colon length was suppressed in the AM treatment group compared to the control group. In addition, as a result of biochemical analysis, AM administration significantly reduced serum glutamic oxalacetic transaminase, glutamic pyruvate transaminase levels and tissue malondialdehyde levels. As a result of confirming the protein expression level through western blot, AM administration significantly decreased the expression of NADPH-related proteins such as NOX2, p22^phox, and iNOS, but significantly increased the expression of SOD, catalase, and GPx-1/2. Conclusions : AM may improve DSS-induced UC in mice by modulating NADPH and antioxidant-related proteins. In conclusion, AM showed an antioxidant effect through the improvement of oxidative stress on UC.

Overproduction of reactive oxygen species (ROS), including nitric oxide (NO), could be associated with the pathogenesis of various diseases such as cancer and chronic inflammation. Inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) are known to play key roles in the development of these diseases. Cedrela sinensis leaves have been used in Asian countries as a traditional remedy for enteritis, dysentery and itching. In the present study, we investigated the anti-inflammatory effects of Cedrela sinensis leaves in lipopolysaccharide (LPS)- stimulated RAW 264.7 macrophages. Powder of C. sinensis leaves was extracted with 95% ethanol and fractionated with a series of organic solvents including n-hexane, dichloromethane, ethyl acetate, n-butanol, and water. The dichloromethane (DCM) fraction strongly inhibited NO production possibly by down-regulating iNOS and COX-2 expression, as determined by Western blotting. Hydrogen peroxide-induced generation of reactive oxygen species (ROS) was also effectively inhibited by the DCM fraction from C. sinensis leaves. In addition, C. sinensis inhibited LPS-mediated p65 activation via the prevention of IκB-$\alpha$ phosphorylation. Furthermore, mitogen-activated protein kinases (MAPKs) such as ERK 1/2 and p38 were found to affect the expression of iNOS and COX-2 in the cells. Taken together, our data suggest that leaves of C. sinensis could be used as a potential source for anti-inflammatory agents.

비록 천연유래물질 중의 하나인 통초가 항산화작용, 항염증작용 및 해열작용과 같은 효능이 있다고 알려져있지만, 종양에서의 암예방효능에 대한 연구는 보고된 바가 없다. 본 연구에서는 사람 자궁경부암세포주인 HEP-2세포에서 통초메탄올추출물의 증식억제 효능 및 관련 분자표적을 확인하고자 하였다. 통초메탄올추출물은 세포증식을 유의성있게 억제하고, 세포사멸을 유도하는 것으로 나타났다. 또한, Bid의 발현에 영향을 주어 truncation을 유도하고, 이로 인해 cytochrome c가 마이토콘드리아에서 세포질로 이동하도록 유도하였지만, Bid 이외의 다른 Bcl-2 family에는 영향을 주지 못했다. 따라서, 이러한 결과를 종합해 볼 때, 통초메탄올추출물은 자궁경부암에서 암예방효능을 가진 잠재성있는 천연추출물이 될 수 있을 것으로 사료된다.

Luteolin is a plant flavonoid which exhibits anti-oxidative, anti-inflammatory and anti-tumor effects. However, the antiproliferative potential of luteolin is not fully understood. In this study, we investigated the effect of luteolin on cell cycling and apoptosis in human esophageal squamous carcinoma cell line Eca109 cells. MTT assays showed that luteolin had obvious cytotoxicity on Eca109 with an $IC_{50}$ of $70.7{\pm}1.72{\mu}M$ at 24h. Luteolin arrested cell cycle progression in the G0/G1 phase and prevented entry into S phase in a dose- and time-dependent manner. as assessed by FCM. Luteolin induced apoptosis of Eca109 cells was demonstrated by AO/EB staining assay and annexin V-FITC/PI staining. Moreover, luteolin downregulated the expression of cyclin D1, survivin and c-myc, and it also upregulated the expression of p53, in line with the fact that luteolin was able to inhibit Eca109 cell proliferation.
