Anti-infammatory, analgesic and ulcerogenic activities of fentiazac were investigated in comparison with those of acetylsalicylic acid, fenbufen, naproxen and phenylbutazone. On the anti-inflammatory activity in carrageenin-induced rat paw edema and the analgesic activity on writhing syndrome induced with acetic acid in mice, fentiazac displayed more potent effect than acetylsalicylic acid, fenbufen and pbenylbutazone. But the ulcerogenic action of fentiazac on gastrointestinal tract in fasting rats was less than that of reference drugs. From these investigation, fentiazac seemed to indicate a poor correlation between the extent of anti-inflammatory activity and ulcerogenic action.

The purpose of this study was to confirm the possiblility of Zingiber mioga as a cosmetic material. For this we carried out biologically activated material characteristic evaluation about anti-oxidant, anti-inflammatory, wrinkle reduction effects using Zingiber mioga extract. To carry out this experiment, we extracted Zingiber mioga extract from Zingiber mioga flowers exract (ZMF) and Zingiber mioga leaves exract (ZML) with 70% ethanol. In order to evaluate the anti-inflammatory effect, we tested the toxicity and the hindrance activity to nitric oxide of samples using macrophages (RAW 264.7 cells). After we measured DPPH radical scavenging activity, ABTS+ radical scavenging activity and superoxide dismutase (SOD)-like activity of the Zingiber mioga extracts, we knew that they increased depending on their concentration. ZMF showed higher antioxidant activity than ZML after the measurement of ABTS+ radial scavenging activity and superoxide desmutase (SOD)-like activity. According to the measurement result of Nitric oxide inhibition activity we knew that ZMF reduced NO productions in a concentration-dependent manner. After the measurement of the biosynthesis quantity of pro-collagen type-1, we knew that its excellent effect appeared 110% or more at the concentration of 25 ㎍/ml. And at the same concentration, the result of the measurement of metalloprotease (MMP)-1 inhibition effect showed the 20% activation. In conclusion, ZMF is expected to be applied as a cosmetic material for wrinkle reduction. Zingiber mioga is believed to be used as a natural cosmetic material because it has been proven to have antioxidant, anti-inflammatory, and wrinkle-improving effects.

This study is for checking the possibility of Lentinula edodes as cosmetic materials. For this we carried out biological active evaluation about anti-oxidant and anti-inflammatory effects by Lentinula edodes extracts. We extracted Lentinula edodes with water and 70% ethanol and then in order to evaluate anti-oxidant activity we treated samples by concentrations (100, 500, 1000) ${\mu}g/ml$ and carried out 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, the activity of 2,2'-azino-bis ( 3-ethylbenzothiazoline-6-sulphonic acid )-diammonium salt (ABTS) cation radical scavenging and superoxide dismutase(SOD) like activity. Also, in order to evaluate effect of anti-inflammatory the samples in macrophages(RAW 264.7 cells), we carried out evaluation of cell viability, nitric oxide inhibitory activity western blot. The results of DPPH, $ABTS^+$ radical scavenging activity and SOD-like activity of the Lentinula edodes extracts increased in dose-dependent manner. The cytotoxic of samples by MTT assay showed no toxicity at the concentrations of 10, 25 and $50{\mu}g/ml$ of Lentinula edodes extract. Nitric oxide inhibition activity results showed that the extracts reduced NO productions in a concentration-dependent manner. Expression of inflammatory cytokines as $TNF-{\alpha}$, $PGE_2$ and $IL-1{\beta}$ decreased in a concentration-dependent manner and iNOS and COX-2 proteins expression rates were decreased significantly in western blot analysis. From the results of the experiment, it was comfirmed that the Lentinula edodes extracts had excellent anti-oxidant and anti-inflammatory effect and could be used as a safe natural cosmetic material in the future.

We investigated the anti-inflammatory effects of aqueous extract of Artemisia capillaris Thunb. (AEAC), a traditional Korean herb for remedying liver disease, for suppression in the process of lipopolysaccharide (LPS)-induced inflammation in the liver of rat. Level of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) and lactate dehydrogenase (LDH) was increased in the serum of LPS-treated rats compared to normal, however, in the rats pretreated with AEAC, the increase of GOT, GPT and LDH value was arrested. More severe histological changes of liver such as cloudy swelling, hydropic degeneration, Kupffer cell reaction and inflammatory cells infiltration were demonstrated in the rats challenged with LPS compared with normal. Fewer scores of these changes were observed in rats pretreated with AEAC. Immunohistochemical analysis showed that while the expression of the nuclear factor (NF)-kBp65, inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-$\alpha$ and COX (cyclooxygenase)-2 tended to increase, that of inhibitory (I)-kBa was decreased in the hepatocytes of rats challenged with LPS. A slight decline of NF-kBp65, TNF-$\alpha$ and COX-2, but increase of I-kB$\alpha$ were observed in the hepatocytes of the rats pretreated with AEAC. These results suggest that AEAC may act as a therapeutic agent for liver disease through a regulation of inflammation-related proteins.
