Objectives : Elastic fibers are found in the skin, lungs, arteries, veins and other structures. Elastases destroy the elastic fibers and cause the emphysema and pulmonary hypertension. Oxidative stress is needed for these pathologic changes. Accordingly, present study was designed to investigate the effect of Yukmigeehwang-hwan extracts (YHE) on elastase activity and anti-oxidative effects of YHE. Methods : The inhibitory effects on elastase and DPPH and NO free radical scavenging activities of YHE were measured. Results : The elastase activity was significantly inhibited by YHE. YHE significantly scavenged DPPH and NO free radicals as well. Conclusion : YHE showed the elastase-inhibiting effects and anti-oxidative activities in vitro. These results suggest that YHE may have potential roles in the treatment of pulmonary emphysema and pulmonary hypertension.

Purpose: In this study, we investigated the anti-thrombotic efficacy of "Eungapbang-gagam(EGB)" currently used in clinical treatment of PID Methods: We studied inhibitory effect of platelet cohesion, suppressive effect of GPIIb/IIIa activity, inhibitory effect of $TXB_2$ and $PGE_2$ biosynthesis, and oxidative damage suppression effects of "EGB" in vitro. Also, suppression of pulmonary embolism and changes of related factors in dextran coagulation condition model were studied in vivo. Results: In this study, EGB extract showed dose-dependent inhibitory effect on platelet coagulation induced by ADP, epinephrine, collagen, arachidonic acid. Also it showed dose-dependent inhibition effect on GPIIb/IIIa activities compared to the control group. EGB extract significantly suppressed the decrease of speed of bloodstream caused by blood coagulation in dextran coagulation condition model and increased the number of platelets and amount of fibrinogen, and decreased the APTT in dextran coagulation condition model compared to the control group. EGB extract showed dose-dependent decrease of oxidative damages caused by DPPH and superoxide anion radicals, whereas dose-dependent increase of superoxide dismutase like activity was observed compared to the control group. Conclusion: We confirmed the anti-thrombosis and anti-oxidative efficacy of "Eungapbang-gagam".

Methods : The extracts of HScF and HR were tested in vivo for their anti-oxidative effects. SD Rats were injected with the AAPH (2.2'-azobis (2-aminodinopropane) hydrochloride) to induce the acute oxidization stress, and the oxidized rats were administered with the HScF and HR decoction orally. The RBC, WBC and PLT populations in plasma, and the blood chemistry levels of the rats were measured to observe the overall changes in the blood. The anti-oxidative effects of the HScF and HR decoctions were investigated on the liver tissues of the oxidated rats. Results : 1. Thrombocyte decreased significantly in the group medicated with HScF. 2. Blood glucose increased significantly in the group medicated with HR. 3. SOD activity increased significantly in both the group medicated with HScF and that with HR. 4. NO concentration decreased significantly in both the group medicated with HScF and that with HR. 5.

Samul-tang (SMT), which was firstly described in (Hwajegukbang) Song dynasty, is well known remedy for blood diseases in Oriental medicine. SMT is traditional herbal-remedy composed of Rehmanniae Radix Preparat, Angelicae Gigantis Radix, Cnidii Rhizoma and Paeoniae Radix. Recently, SMT has known to have anti-oxidative action. However, the reports on anti-oxidantic action in neuroglial cells are rare. In addition, the exact mechanisms are unclear. For these reasons, we investigated the protective effects of SMT on cell death induced by oxidative stress using C6 glioma cells. In our results, SMT accelerated proliferation rates of C6 cells in vitro. In addition, levels of LDH release induced by oxidative stress were lowered by treatment with SMT. Finally, protective effects on cell death induced by chemicals such as paraquat and rotenone were observed. In conclusion, these results suggest the possibility to protect brain cell or neuronal cell from damage induced by oxidative stress.

Catalpol, an iridoid glucoside, isolated from the root of Rehmannia glutinosa Libosch. It possesses a broad range of biological and pharmacological activity including anti-tumor, anti-inflammation and anti-oxidant by acting as a free radical scavenger. Therefore, in this study, the effects of catalpol on blastocyst development, expression levels of reactive oxygen species (ROS) and apoptotic index were investigated in porcine embryos. After in vitro maturation and fertilization, porcine embryos were cultured for 6 days in porcine zygote medium 3 (PZM-3) supplemented with catalpol (0, 100, 200 and $400{\mu}M$, respectively). Blastocyst development not significantly improved in the catalpol treated group when compared with control group. Otherwise, the intracelluar levels of ROS were decreased and the numbers of apoptotic nuclei were reduced in the catalpol ($100{\mu}M$) treated porcine blastocysts (P<0.05). On the other hand, blastocyst development was significantly improved in the catalpol ($100{\mu}M$) treated group when compared with the untreated catalpol group under $H_2O_2$ ($200{\mu}M$) induced oxidative stress (P<0.05). Otherwise, the intracellular levels of ROS in catalpol ($100{\mu}M$) treated group were significantly decreased in the untreated catalpol group under $H_2O_2$ ($200{\mu}M$) induced oxidative stress (P<0.05). Furthermore, the total cell numbers of blastocysts were significantly increased (P<0.05) in the catalpol ($100{\mu}M$) treated group under $H_2O_2$ ($200{\mu}M$) induced oxidative stress, whereas numbers of apoptoic nuclei were significantly reduced (P<0.05). In conclusion, our results indicate that treatment of catalpol may have important implications for improving developmental competence and preimplantation quality of porcine embryos through its anti-oxidant and anti-apoptotic effect.

We aimed to assess the anti-inflammatory and antioxidative properties of KHG26792, a novel azetidine derivative, in amyloid ${\beta}$ ($A{\beta}$)-treated primary microglial cells. KHG26792 attenuated the $A{\beta}-induced$ production of inflammatory mediators such as IL-6, $IL-1{\beta}$, $TNF-{\alpha}$, and nitric oxide. The levels of protein oxidation, lipid peroxidation, ROS, and NADHP oxidase enhanced by $A{\beta}$ were also downregulated by KHG26792 treatment. The effects of KHG26792 against the $A{\beta}-induced$ increases in inflammatory cytokine levels and oxidative stress were achieved by increasing the phosphorylation of $Akt/GSK-3{\beta}$ signaling and by decreasing the $A{\beta}-induced$ translocation of $NF-{\kappa}B$. Our results provide novel insights into the use of KHG26792 as a potential agent against $A{\beta}$ toxicity, including its role in the reduction of inflammation and oxidative stress. Nevertheless, further investigations of cellular signaling are required to clarify the in vivo effects of KHG26792 against $A{\beta}-induced$ toxicity.
