This study was carried out to search for the anti-inflammatory activities of ethanol extracts obtained from 5 kinds of oriental medical plant; Pleuropterus multiflorus extract (PME), Acorus calamus L. extract (ACE), Lithospermum erythrorhizon Siebold & Zucc. extract (LEE), Xanthium strumarium L. extract (XSE), Lonicera japonica extract (LJE), which have traditionally been used as a drug in oriental medical plants in Korea. XSE showed cytotoxicity at 100, $200{\mu}g/ml$ concentration in RAW264.7 cells (p<0.05) and ACE showed cytotoxicity at $200{\mu}g/ml$ concentration in RAW264.7 cells (p<0.05). But other oriental medical plants did not showed cytotoxicity was observed in RAW264.7 cells below $200{\mu}g/ml$ concentration. These extracts at non-toxic concentrations showed anti-inflammatory effects. PME, ACE, XSE and LJE showed a concentration-dependent inhibitory effect on NO production and $PGE_2$ production in LPS-induced RAW264.7 cells. In particular, XSE showed the highest NO production inhibition ($52.9{\mu}g/ml$, $IC_{50}$) as well as the highest $PGE_2$ production inhibition at $50{\mu}g/ml$ (73.6%). ACE and LEE showed cell proliferation effects on HaCaT keratinocyte cells. Especially, LEE showed 21.1, 53.5 and 99.6% proliferative activity by incubation for 1, 3, 5days at $100{\mu}g/ml$ concentration. ACE also showed 11.2, 26.0% proliferative activity for 1day and 3days at $10{\mu}g/ml$ concentration. As a result of this study, ethanol extracts obtained from 5 kinds of oriental medical plant showed anti-inflammatory activity and HaCaT cell regeneration effect.

The cosmetic and stimulating effects of lemon oil have been widely proven in the fields of beauty therapy and psychology therapy. But the lemon oil's proper effects on the anti asthma and the anti inflammation have not rarely been verified. This study was conducted to find out the lemon oil's effects on the anti asthma and anti inflammation in the OVA-induced allergic asthma mice model. OVA-induced allergic asthma mice were divided into 4 groups consisting of normal group, control group, positive control group and experimental group. 0.3% of lemon oil was nebulized to experimental group for 3 weeks on a basis of 3 times per week and 30 min each time. After 6 weeks from the initial experiment, the degree of hyper activeness of respiratory system, the hematological change, the amount of the cytokein in serum, the change of airway organization were evaluated. The results showed that lemon oil controled effectively the hyper activeness of respiratory system and restricted the multiplication of cells in acidophil in terms of statistical significance. It also turned out that lemon oil restricted effectively the infection of airway reaction and the hyper sensitiveness of respiratory system by controlling the creation of histamine(cytokein) and IgE.

Purpose: This study was conducted in order to investigate the protective effects of ethanolic extract of Acanthopanax koreanum Nakai (AE) against carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Methods: Male Sprague-Dawley rats were randomly divided into four groups in order to receive the following experimental diets with intraperitoneal injection of $CCl_4$ (2.0 mL/kg body weight, 20% solution 0.65 mL) for eight weeks (n = 8 per group): $CCl_4$ control (CON), $CCl_4$ + AE 1% (AE1), $CCl_4$ + AE 3% (AE3), or $CCl_4$ + acanthoic acid 0.037%, which is equivalent to AE 3% (AA). Results: Highest serum ALT activity and albumin level were observed in the $CCL_4$ control group, but showed a significant decrease by either AE or AA supplementation in a dose-dependent manner (p = 0.0063 and 0.0076, respectively). Both hemotoxylin and eosin staining and Masson's staining indicated remarkable prevention of $CCl_4$-induced liver damage in the AE3 group. $TNF{\alpha}$ and IL-6 production were significantly lowered in the AE treated groups, but not in the AA group (p = 0.0016 and p = 0.0002, respectively). The effects of AE3 were greater than those of AA for inflammation and liver toxicity biomarkers. Conclusion: Taken together, the results suggested that ethanolic extract of Acanthopanax koreanum Nakai provided hepatoprotective effects, leading to the reduction of inflammatory response. In addition, the effect of AE was superior to that of single compound AA.

Phallus impudicus var. impudicus L. is an edible mushroom that has long been used as folk medicine in China. The aim of this study was to evaluate the antioxidant, anti-cholinesterase, and inflammation inhibitory activities of a methanol extract of fruiting bodies of P. impudicus var. impudicus L. The extract exhibited good 1,1-diphenyl-2-picrylhydrazyl scavenging activity, excellent ferrous ion chelating activity, and moderate hydroxyl radical scavenging activity compared with BHT at 2.0 mg/ml. However, the reducing power of the extract was significantly lower than that the BHT positive control. Although the inhibitory activities of methanol extract on acetylcholinesterase and butyryl cholinesterase were significantly lower than the galanthamine positive control at the concentration tested, the inhibition of acetylcholinesterase and butyryl cholinesterase was 52.83% and 55.17%, respectively, at 1.0 mg/ml. The methanol extract also demonstrated excellent inhibition of inflammation-related activities, such as production of nitric oxide in lipopolysaccharide-induced RAW 264.7 macrophage cells and acute edema induced by administration of carrageenan on the hind paw of rats. The collective results suggest that the fruiting body of P. impudicus var. impudicus L. might be a good source of antioxidant, anti-cholinesterase, and anti-inflammation compounds.

In this study, the anti-inflammatory and antioxidant effects of aerial parts of Rumex acetosa L. extract were confirmed to prevent various inflammatory diseases and skin aging caused by excessive oxidative stress. As a result of ABTS assay, it was confirmed that the radical scavenging ability increased in a concentration-dependent manner. ROS inhibitory ability was confirmed through DCF-DA assay, and concentration-dependent inhibition of ROS production was confirmed. The effect of inhibiting cell nuclear damage according to ROS was confirmed through DAPI staining. In addition, it was confirmed that the mRNA expression levels of iNOS and COX-2 were inhibited in a concentration-dependent manner through qPCR. As a result of confirming the protein levels of iNOS and COX-2 by western blotting, iNOS was significantly decreased at all concentrations, and COX-2 was significantly decreased at 800 ㎍/mL. The inhibitory effect on the production of NO generated by iNOS was confirmed by NO assay, and NO was decreased in a concentration-dependent manner. In addition, phosphorylation of ERK and JNK in the MAPKs signaling pathway were inhibited. Therefore, Rumex acetosa L. has the potential to be used as an anti-inflammatory and antioxidant cosmetic raw material by showing anti-inflammatory and antioxidant effects through the MAPKs pathway.
