The essential oils from the roots of Codonopsis lanceolata and the cultivated callus were analysed and compared by gaschromatography-mass spectrometry. In the experimental study of cell culture, it appeared that 2,4-dichlorophenoxy acetic acid in the culture medium induced higher production of essential oils in the callus than indole acetic acid. The growth of callus was inhibited by illumination of the light. The production of essential oil in cultured cells was increased by the addition of biosynthetic precursors. The essential oils from the roots of Codonopsis lanceolata and the cultured callus showed different compositions. Tetradecanoic acid, 1,1,-dimethoxyl 4-methoxy phenol, 9,12-octadecanoic acid and hexadecanoic acid were identified as main components of the cultured callus oil.

Haemophilus K-12 producing novel sulfotransferase was isolated from mouce intestinal flora. The enzyme catalyzed the transfer of sulfate group from p-nitrophenylsulfate to phenolic compounds. The optimum medium condition for the sulfotransferase production was 0.2% sucrose, 1% yeast extract, $Na_{2}HPO_4$ and 0.5% NaCl. The enzyme production was induced by donor substrate, but was not by accepters. When p-nitrophenylsulfate was used as a donor substrate, 1-naphthol was best substrate, followed by phenol, p-acetaminophenol and tyramine.

Morinda officinalis (Rubiaceae) is a medicinal herb that has traditionally been used for the treatment of skin inflammation. The present study was to investigate the inhibitory efficacy of matrix metalloproteinases-1 (MMP-1) of the extracts of the root of M. officinalis, which was autoclaved at $132^{\circ}C$ and $1.2kgf/cm^2$ for 15 min using an autoclave. The composition of the extracts were compared with that prepared without autoclaved treatment. Total phenol and flavonoid contents were analyzed for the autoclaved M. officinalis root extract (AME) and M. officinalis root extract (ME). Results showed that the autoclaved AME contained total phenol and flavonoid contents 1.5-fold times more than those from ME. AME showed DPPH and superoxide radical scavenging activities as 79.25% and 94.5%, respectively, at the concentration of $500{\mu}g/mL$. In anti-inflammatory assay, AME inhibited the activity of COX-2 and 5-LOX metabolites. In addition, AME showed higher an inhibition rate in MMP-1 expression than ME in UVA-irradiated human dermal fibroblast (HDF) without any significant cytotoxicity. UVB-induced cytotoxicity and cell death were effectively suppressed by AME. In conclusion, autoclaving the M. officinalis root increased the phenol and flavonoid contents. The extracts of the autoclaved M. officinalis enhanced the antioxidant, anti-inflammatory and anti-MMP-1 effects. Thus, the extracts could be an useful active ingredient in cosmetics.

Melaleuca leucadendron L. has been used as a tranquilizing, sedating, evil-dispelling and pain-relieving agent. We examined the effects of M. leucadendron L. extracts on oxidative stress and inflammation. M. leucadendron L. was extracted with methanol (MeOH) and then fractionated with chloroform ($CHCl_3$) and butanol (BuOH). Antioxidant activity of the MeOH extract and BuOH fraction were higher than that of both ${\alpha}$-tocopherol and butyrated hydroxytoluene (BHT). Total phenol content in the extracts of M. leucadendron L., especially the BuOH fraction, well correlated with the antioxidant activity. The anti-inflammatory activity of BuOH extracts were investigated by lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production, and cyclooxygenase-2 (COX-2) expression in RAW 264.7 macrophages. The BuOH fraction significantly inhibited LPS-induced NO and $PGE_2$ production. Furthermore, BuOH extract of M. leucadendron L. inhibited the expression of COX-2 and iNOS protein without an appreciable cytotoxic effect on RAW264.7 cells. The extract of M. leucadendron L. also suppressed the phosphorylation of inhibitor ${\kappa}B{\alpha}$ ($I{\kappa}B{\alpha}$) and its degradation associated with nuclear factor-${\kappa}B$ (NF-${\kappa}B$) activation. Furthermore, BuOH fraction inhibited LPS-induced NF-${\kappa}B$ transcriptional activity in a dose-dependent manner. These results suggested that M. leucadendron L. could be useful as a natural antioxidant and anti-inflammatory resource.

Gallotannin (GT) is derived from plant poly phenol and is associated with biological actions in a wide range of cells. In this study, we evaluated the effect of GTon apoptosis and cyclooxygenase-2 (COX-2) expression and attempted to shed light on the mechanism of action in A549 human lung carcinoma cells. We found that GT dramatically induced apoptosis as demonstrated by expression of p53 and active caspase-3 via western blot analysis and fragmented DNA as detected by DNA fragmentation and DAPI staining. We also observed that GT significantly causes COX-2 expression in a dose-dependent manner determined by western blot analysis. Phosphorylation of Akt and p38 was considerably increased by GT in A549 human lung carcinoma cells. Inhibition of Akt and p38kinase with LY294002 or SB203580 suppressed GT-induced apoptosis and COX-2 expression. Furthermore, we have shown that prevention of COX-2 with NS398 or indomethacin does not any effects on apoptosis induced by GT. Taken together, our present results suggest that GT regulates apoptosis and COX-2 expression through Akt and p38kinase pathway in A549, human lung carcinoma cells.

Objective: Diseases of the respiratory system are one of the main causes of death and include situation such as chronic obstructive pulmonary disease, pneumonia or asthma. Medicinal plants have beneficial effects on multiple diseases include respiratory disorders like asthma and bronchitis. The aim of this study was to evaluate the effects of U. dioica and L. Album on tracheal smooth muscle contraction. Material and methods: Hydroalcoholic extracts of L. Album and U. Dioica aerial parts were prepared by maceration method and standardized based on their total phenol content. The effect of the extracts on the KCl-induced contraction of rat trachea was examined in an organ bath chamber. Data was analyzed with spss software 22. Results: The extract of L. Album (5 mg/ml), similar to theophylline (20 mM), significantly reduced the KCl-induced tracheal contraction. On the other hand, U. Dioica (1 mg/ml and 5 mg/ml) augmented the KCl-induced contraction. Conclusion: The relaxant effect of L. Album on the trachea makes it as a candidate for the managing patients with asthma and obstructive pulmonary diseases. But because of U. Dioica potential constrictive effect on the trachea it is suggested that patients avoid consuming it.

A multi-walled carbon nanotube (MWNT) support with dual properties, an ionic property via tetra-amine and unpaired electrons via tri-amine, was prepared by radiation-induced graft polymerization of glycidyl methacrylate (GMA) and the subsequent amination of its epoxy group. The electrochemical microbial biosensor (EMB) was then fabricated by immobilization of a microbe (Alkaligenes spp.) onto the dual property-modified electrode, which was prepared with the mixture of the MWNT support and a $Nafion^{(R)}$ solution on a glass carbon (GC) electrode surface by a hand-casting method. The sensing range of the prepared EMB for phenol in a phosphate buffer solution was 0.005~7.0 mM. The total concentration of phenolic compounds in a commercial red wine was also determined using the EMB.

Purpurogallin, a natural phenol obtained from oak nutgalls, has been shown to possess antioxidant, anticancer, and anti-inflammatory effects. Recently, in addition to ultraviolet B (UVB) radiation that induces cell apoptosis via oxidative stress, particulate matter 2.5 ($PM_{2.5}$) was shown to trigger excessive production of reactive oxygen species. In this study, we observed that UVB radiation and $PM_{2.5}$ severely damaged human HaCaT keratinocytes, disrupting cellular DNA, lipids, and proteins and causing mitochondrial depolarization. Purpurogallin protected HaCaT cells from apoptosis induced by UVB radiation and/or $PM_{2.5}$. Furthermore, purpurogallin effectively modulates the pro-apoptotic and anti-apoptotic proteins under UVB irradiation via caspase signaling pathways. Additionally, purpurogallin reduced apoptosis via MAPK signaling pathways, as demonstrated using MAPK-p38, ERK, and JNK inhibitors. These results indicate that purpurogallin possesses antioxidant effects and protects cells from damage and apoptosis induced by UVB radiation and $PM_{2.5}$.

Estrogens induce pronounced structural and functional changes in male and female reproductive system, but the exact mechanisms of estrogen are not fully understood. In relation to estrogen's function, the present study was designed to identify effects of estrogen receptor agonist, 4,4',4"- (4-propyl-[1H]-pyrazole-1,3,5-triyl)tris phenol (PPT) in the reproductive organ of the female mouse. The PPT was subcutaneously given to adult female mice at a weekly dosage of 3 mg in a volume 0.06 mL of vehicle for 3, 5 or 8 weeks whereas controls received weekly injections of the castor oil vehicle. Effects of PPT on reproductive organs were analyzed using a light microscope. PPT induced decreases of body, ovary and adipose tissue weights with experimental time. Ovary diameter of PPT treatment group was reduced as compared with control group. The number of Graffian follicle and corpus luteum was reduced in PPT treatment group. The luminal diameter of uterus was increased in relation with decrease of myometrium and endometrium height by PPT administration. The number of uterine glands was decreased by PPT treatment. These data indicate that PPT treatment induced morphological change of female reproductive organs resulting in alteration of fertility.

In vitro, we measure total phenol contents, total flavonoid contents, DPPH free radical scavenging activity, ABTS cation radical scavenging activity of Gamikyejakjimogawusul-tang, effect of GK extract on ROS(Reactive Ooxygen Species) production to estimate a anti-oxidant capacity, and we also measure effect of GK extract on NO (Nitric Oxid), IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF production in RAW 264.7 cells to estimate a anti-inflammatory efficacy. In vivo, we compare a rheumatoid arthritis manifestation between control and experimental group and estimate a AI. Then we check effect of GKHA on the level of WBC, neutrophil, lympocyte, monocyte in the blood to see the effect of immune cells in blood. In addition we measure effect of GKHA on the level of hs-CRP, IgM, IgG, IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF in serum. We observe effects of GKHA on imaging of cartilage degeneration using micro CT-arthrography in paw hind. And we calculate effects of GKHA that reduced BV ratio, BS/BV ratio using 3D Micro-CT. Lastly we observe effects of GKHA histopathologic examination analysis. Results : 1. The toxicity on liver and kidney was disregardable and the cytotoxicity against RAW 264.7 cells was also disregardable. 1. Total phenol contents and total flavonoid contents in GK extract were in high level. 2. DPPH free radical scavenging activity and ABTS cation radical scavenging activity were increased according to concentration of GK extract 3. ROS production was significantly decreased in GK extract (at 10, $100{\mu}g/ml$). 4. NO, IL-6, TNF-${\alpha}$, MCP-1 production were significantly decreased in GK extract(at 10, $100{\mu}g/ml$). IL-17, GM-CSF production were significantly decreased in GK extract(at 1, 10, $100{\mu}g/ml$). IL-$1{\beta}$, IL-21 production were also decreased but there was no statistical significance. 5. 25x observation after H&E and M-T staining, infiltration of immune cells and subsidence of the cartilage and damage to the synovial cells were decreased.
