  • The aim of this study is to investigate the antioxidant and intracellular anti-inflammatory efficacy of blueberry leaf extracted with hot water (BLW), 70% ethanol (BLE), and 70% acetone (BLA) in RAW 264.7 macrophages. In order to evaluate the anti-inflammatory effect of blueberry leaf extracts, RAW 264.7 macrophages were stimulated with lipopolysaccharide (LPS) to induce the production of inflammation-related factors, which were measure by Western blotting and real-time PCR methods. i-NOS, COX-2 protein, and mRNA expression showed concentration-dependent decrease. The decreases in the mRNA expression levels of interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and prostaglandin $E_2$ ($PGE_2$) were concentration-dependent. Further, the antioxidant effects of blueberry leaf on total polyphenol contents, electron donating ability and $ABTS^+$ radical scavenging activity were evaluated. The total polyphenol contents of BLW, BLE, and BLA were $217.04{\pm}2.98$, $156.72{\pm}3.90$, and $182.88{\pm}3.02mg\;TAE/g$, respectively, while the electron donating abilities at $1,000{\mu}g/mL$ of BLW, BLE, and BLA were 81.7, 79.6, and 79.3%, respectively. The $ABTS^+$ radical scavenging activity was fond to be concentration dependent. The nitric oxide (NO) production inhibition activities at $50{\mu}g/mL$ of BLW, BLE, and BLA were 35.1, 42.4 and 42.7%, respectively. In conclusion, the antioxidant and anti-inflammatory test results indicate that blueberry leaf extracts (BLW, BLE, and BLA) can be used as potential anti-inflammatory agents.

  • Betulinic acid (BA), a pentacyclic triterpene isolated from Lycopus lucidus, has been reported to be a selective inducer of apoptosis in various human cancer and shown anti-inflammatory and immunomodulatory properties. We postulated that BA modulates the immunomodulatory properties at least two groups of protein mediators of inflammation, interlukin-1$\beta$ (IL-1$\beta$) and the tumor necrosis factor- $\alpha$ (TNF-$\alpha$) on the basis of the critical role of the monocytes and tissue macrophages in inflammatory and immune responses. TNF-$\alpha$ and IL-1$\beta$ were produced by BA in a dose dependent manner at concentration of 0.625 and 10 $\mu$g/mL. The production of NO associated with iNOS was inhibited when treated with LPS at the concentration of 2.5 to 20 $\mu$g/mL of BA whereas COX-2 expression was decreased at 2.5 to 20 $\mu$g/mL. These modulations of inflammatory mediators were examined in LPS-stimulated RAW 264.7 cells and peritoneal macrophages. The morphology of macrophage was also examined and enhanced surface CD 40 molecule was expressed when treated BA at 0.625∼5 $\mu$g/mL with or without LPS. Furthermore, BA (20 $\mu$g/mL) enhanced apoptosis by producing DNA ladder in the RAW 264.7 cells. Our results indicated that BA induced activation of macrophage and pro-inflammatory cytokines. This may provide a molecular basis for the ability of BA to mediate macrophage, suppress inflammation, and modulate the immune response.

  • Objectives : We compared with the effects of different parts (root head, root body and hairy root) of Angelica gigas Nakai (Angelicae Gigantis Radix, AG) with on middle cerebral artery occlusion(MCAO)-induced ischemic rats, and on LPS-induced inflammatory response in BV2 microglia. Methods : The 30% ethanol and water extracts of different parts of AG were prepared. Each extract (50 and 100 mg/kg) was administrated intraperitoneally once in MCAO-induced ischemic rats. We measured infarction volumes by TTC staining, and investigated the expression of iNOS, Bax, Bcl-2 and caspase-3 by Western blot. BV2 cells were treated with each extract for 30 min, and then stimulated with LPS. The levels of NO was measured by Griess assay. The expression of iNOS, Cox-2 and proinflammatory cytokines ($TNF-{\alpha}$, $IL-1{\beta}$, and IL-6) were determined RT-PCR and Western blot. The phosphorylation of ERK1/2 and JNK MAPK was determined by Western blot. Results : Among different parts of AG, the 30% ethanol and water extracts of hairy root significantly decreased infarction volume in ischemic brains and inhibited the expression of iNOS, bax and caspase-3. The extracts of hairy root significantly inhibited LPS-induced production of NO, $TNF-{\alpha}$ and IL-6 in BV2 cells, and suppressed the expression of iNOS and COX-2. The hairy root extracts attenuated LPS-induced phosphorylation of ERK1/2 and JNK MAPK in BV2 cells. Conclusions : Our results indicate that the root hairy of AG has a good neuroprotective and anti-inflammatory effects in ischemic stroke compared to other parts.

  • Ultraviolet B (UVB) irradiation induces both production of reactive oxygen species (ROS) and glucocorticoids (GCs)-mediated stress responses such as an increase of $11{\beta}$-hydroxysteroid dehydrogenase type 1 ($11{\beta}$-HSD1) activity in skin. In addition, ROS-induced inflammatory mediators and proinflammatory cytokines trigger skin inflammation. In this study, as $11{\beta}$-HSD1 inhibitor recovered a decrease of catalase expression, we investigated whether Trapa japonica (TJ) extract and its fractions could inhibit $11{\beta}$-HSD1/ROS-induced skin inflammation in HaCaT keratinocytes. TJ extract and its fractions inhibited expressions of $11{\beta}$-HSD1 as well as the increase of ROS in UVB-exposed HaCaT keratinocytes. Moreover, proinflammatory cytokines such as interleukin (IL)- ${\alpha}$, - ${\beta}$ and tumor necrosis factor (TNF)-${\alpha}$, and cyclooxygenase (COX)-2 and inducible NO synthase (iNOS) as inflammatory mediators were also inhibited in both mRNA and protein levels. Finally, prostaglandin $E_2$ ($PGE_2$) produced by COX-2 was inhibited effectively by TJ extract and its fractions. Taken together, these results suggest that TJ extract could be a potential anti-inflammatory ingredient to inhibit UVB-induced inflammation in skin.

  • Cheongpyesagan-tang (CP) is one of the traditional medicinal prescription to treat Taeumin (太陰人)'s disease. It has been commonly used for the treatment of stroke, arthritis, diabetes and obesity. In this study, we investigated an anti-inflammatory potential of CP water extract. We examined the effects of CP on the lipopolysarccharide (LPS)-induced production of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$). We also examined the levels of protein or mRNA of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and proinflammatory cytokines in RAW 264.7 cells. CP inhibited NO and $PGE_2$ production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, CP decreased the mRNA expression of interleukin-6 (IL-6), interleukin-$1{\beta}$ (IL-$1{\beta}$), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). These results suggest that CP has potential as anti-inflammatory therapeutic medicine.
