Objectives : JianTeng-Yuan(交藤圓) is said to be a prescription for preservation of health in ${\ulcorner}$HuaTuo ZhongZangJing(華陀 中藏經)${\lrcorner}$. It is known to have the effect of Bu-Shen(補腎: strengthening kidney) and Yi-Shou(益壽: prolonging the span of one's life). This study investigates whether JTY is effective on inhibition of oxidation stress. Methods : Sprague-Dawley Rats(12-week-old, weight $300{\pm}20g$) were divided into 3 groups. Normal group(n=8) was injected PBS(1ml/body, s.c) at the back neck's skin. Control group(n=8) was injected D-galactose(50mg/kg, 1ml PBS/body, s.c) to induce pathological animals. JTY group was injected the same treatment for the Control group, and fed containing JTY(10%). The whole groups were treated 1 time per day for 6 weeks. After rats were sacrificed and anti-oxidant enzyme(SOD, CAT, G-px) activity, GSH quantity of RBC and tissue(heart, liver and kidney), plasma Vit-C quantity were examined. Besides, the MDA levels of liver and kidney, lipofuscin of heart and endurance of erythrocyte membrane were measured. Results : In the JTY group, RBC's SOD activity decline was halted by 21% of the normal level, compared to the control group ; G-px activity(unit/g of Hb) increased significantly, compared to the normal group ; and the level of Vit-C in plasma increased by 16%. Heart's SOD activity was kept at the same level as that of the normal group ; and CAT activity decline was halted by 26%. Kidney's CAT and G-px activities were kept at the same level as that shown in the normal group, implying the existence of halting effect. Liver also showed a slight halting effect against the decline of anti-oxidant ability, but the effect was not significant(a=0.05). A comparison between the levels of peroxide in SD rats showed that the level of TBARS in plasma increased significantly in the control group and that it was normal in the JTY group. The livers in the JTY group, compared to those in the control group, showed 36% halting effect of the normal level while their kidney's indicated the level significantly lower than the normal level. Heart's lipofuscin increased significantly in the control group, but was alike in both the JTY and the normal groups. Endurance of erythrocyte membrane(%) decreased significantly in the control group while it was kept at the similar level in both the JTY and the normal groups, indicating the halting effect. Conclusions : This study suggests that JTY is effective to defend oxidation stress caused by D-galactose in the animals. It showed that the anti-oxidant ability was maintained and strengthened. On the other hand, it reduced the level of peroxide in animals. In sum, JTY appeared to have the equilibrium normal physiological function in SD rat.

Objectives : The purpose of the study is to test the antibacterial, anti-inflammatory and antioxidant effects of BPH, which is composed of Pini Densiflorae Nodi Lignum and Querci Acutissimae Fructus, Angelicae Gigantis Radix, Cnidii Rhizoma, Angelicae Dahuricae Radix, Angelicae Tenuissimae Radix. Method : Antibacterial and anti-inflammatory effects of BPH on Propionibacterium acnes, one of anaerobic bacteria species were evaluated by measuring the levels of 2,2-diphenyl-1-picrylhydrazyl (DPPH) elimination and lipid peroxidation. Result : When BPH was applied to CCD-986sk (Human normal fibroblast) to confirm the level of cytokine(tumor necrosis factor-alpha, interleukin-8), its level increased in proportion to that of BPH's concentration, which indicated dose-dependent relationship. Using the Disk diffusion to measure the bacterial growth inhibition zone varying BPH concentration, it was found that the antibacterial effect of BPH was less than that of erythromycin, the control group, but was higher than that of saline, and it increased with higher concentrations. In a liquid culture medium containing BPH, the growth rate of Propionibacterium acnes was decreased by more than 10% at 25% BPH. After adding P. acnes to THP-1 monocyte, and treated it with BPH, and measuring the concentration of TNF-a and IL-8, it was observed that the amount of TNF-alpha and IL-8 significantly decreased depending on the level of BPH concentration. The ability to eliminate DPPH increased with higher BPH concentration. The inhibition of lipid peroxidation was increased by BHT treatment in a dose-dependent manner. Conclusion : Using Propionibacterium acnes, an anaerobic bacteria, we confirmed that BPH has antibacterial, anti-inflammatory and antioxidant effects.

Stevia rebaudiana is a traditional herb used as a sweetener in Brazil and Paraguay as well as Korea and China. This study investigated the efficacy of Stevia rebaudiana methanol extract (SRE) to protect cells against the mitochondrial dysfunction and apoptosis in hepatocyte. To determine the effects of SRE on oxidative stress, we used the human derived hepatocyte cell line, HepG2 cell. Treatment of arachidonic acid (AA)+iron in HepG2 cells synergistically amplified cytotoxicity, as indicated by the excess reactive oxygen species (ROS) and mitochondrial permeability transition by fluorescence activated cell sorter (FACS) and immunoblot analysis. Treatment with SRE protected hepatocytes from AA+iron-induced cellular toxicity, as shown by alterations in the protein levels related with cell viability such as procaspase-3. SRE also prevented the mitochondrial dysfunction induced by AA+iron, and showed anti-oxidant effects as inhibition of $H_2O_2$ production and GSH depletion. Moreover, we measured the effects of SRE on AMP-activated protein kinase (AMPK), a key regulator in determining cell survival or death. Acetyl-CoA Carboxylase (ACC), a direct downstream target of AMPK. SRE increased phosphorylation of ACC, and prevented the inhibition of ACC phosphorylation by AA+iron. These results indicated that SRE has the ability to protect cells against AA+iron-induced $H_2O_2$ production and mitochondrial impairment, which may be mediated with AMPK-ACC pathway.

Azolla는 Azollaceae 속에 속하는 수생 양치류이며 물속에서 질소고정 박테리아인 Anabaena azollae와 공생관계의 식물로써, 현재까지는 질소 함량이 다량 함유되어 쌀 생산량에 크게 기여하는 식물인 것으로 알려져 있다. 이러한 이유로 인해서 중국이나 베트남 북부에서는 수생 식물의 유기 비료 뿐만 아니라 물속 정화기능까지 갖고 있는 것으로 인식되어 농업 및 수산 분야에서 연구가 활발히 진행되고 있는 실정이다. 그러나 이전 연구에서는 Azolla 속의 페놀성 화합물에 대한 연구가 미비하다. 이번 연구에서는 수생식물인 Azolla imbricata의 추출 및 분획을 통하여 Azolla imbricata fraction (AIF) 물질을 얻어 내었으며, DPPH 법을 통한 항산화능력 측정과 lipoxigenase 저해 활성 능력 측정을 통해서 Azolla imbricata의 새로운 능력을 부여하고자 하였다. 이 물질의 항산화 능력과 lipoxygenase 저해 활성능을 나타내는 물질을 분석하였으며, MMP-1 시험에서는 피부 탄력과 보호기능을 위한 콜라겐의 활성 저해율이 75 % 이상인 것으로 나타났다. LC-MASS와 FT-IR, 원소분석 (Element analysis) 을 통하여 구조 분석을 하여 Azolla imbricata가 함유하고 있는 페놀성 화합물의 구조를 알아내었다. 이러한 분석을 통해서 화장품 원료로 잘 사용되지 않았던 수생식물의 사용성을 증대시키고, 천연 화장료 개발로의 응용이 가능할 것으로 기대된다.

Noni has been used for medicinal purposes for more than 2,000 years in South Pacific Polynesia, China and India, and has been heavily ingested as an extract for its excellent antioxidant and anti-inflammatory effects. However, a recent study found that the noni extract causes digestive disorders, kidney problems, and liver diseases, which made it necessary to use it for other purposes than as an extract. In this study, we want to evaluate the potential of noni as an anti-oxidant, anti-inflammatory and anti-wrinkling agent. Methods: Noni was freeze-dried, extracted in water, and concentrated. Skin cells were treated with the noni extract for 24 hrs and then were exposed to UVB (55 mJ/cm²). After 48 hrs of incubation, pro-inflammatory cytokine, elastase, MMP-1 and type-1 procollagen levels were measured by ELISA. Results: To find out the antioxidant effect of the noni extract, the DPPH and ABTS radical scavenging activity experiments were conducted and the noni extract showed 97.0 % and 92.0 % antioxidant efficacy at 200 ㎍/mL respectively. The noni extract (50 and 100 ㎍/mL) decreased IL-6 and TNF-α in RAW 264.7 cells induced by LPS in a concentration-dependent manner. In the RT-PCR experiment involving NO production, the noni extract (50 and 100 ㎍/mL) inhibited NO production by strongly inhibiting iNOS mRNA expression, and also inhibited the elevation of MMP-1 and elastases caused by UVB irradiation by 25.0 % and 7.0 % respectively. In addition, type-1 procollagen was elevated by 20.0 % by the noni extract treatment in HaCaT cells. Conclusion: The noni extract has photoprotective ability by reducing proinflammatory mediators, elastase and MMP-1 production, and elevation of collagen synthesis. Our findings suggest that the noni extract might be a good natural substance to protect against UVB-induced premature skin aging.
