摘要:
The present invention relates to a composition for preventing and treating inflammatory disease containing an Ardisia tinctoria (Ardisia tinctoria Pit.) extract or a fraction thereof as an active ingredient. More specifically, it has been confirmed that an Ardisia tinctoria extract or a fraction thereof suppresses the production of nitric oxide which is sharply increased by inflammation induction, and it has been confirmed that the Ardisia tinctoria extract is effective in markedly reducing the amount of PGE2, IL-6 (interleukin-6) and IL-1 beta cytokine in a dose dependent fashion, and that it inhibits the expression of iNOS and the COX2 gene and protein and inhibits nuclear translocation of p65 protein and phosphorylation of signal transducers. Also, it has been confirmed that the Ardisia tinctoria extract and an ethyl acetate fraction are effective in suppressing inflammation in a carrageenan-induced mouse podedema model as well. Consequently, the Ardisia tinctoria extract or fraction can be used to advantage as an active ingredient in compositions for preventing and treating or alleviating inflammatory related diseases, or compositions for topical skin preparations, cosmetic compositions and health foods.

?Abstract? The present invention relates to an anti-aging and aging retarding composition which contains velvet apple extracts or fractions thereof as active ingredients. More particularly, the velvet apple extracts of the present invention exhibit DPPH free radical scavenging effects and ABTS free radical scavenging effects in a dose-dependent manner. Particularly, ethyl acetate of velvet apple and butanol fractions thereof exhibit excellent antioxidant effects, and therefore, the velvet apple extracts of the present invention may be valuably used as active ingredients of an anti-aging and aging retarding composition, a pharmaceutical composition and a composition for health food.

The present invention relates to a pharmaceutical composition for preventing or treating inflammatory diseases, allergic diseases or asthma, containing a Diospyros blancoi A. DC. extract as an active ingredient. More specifically, a Diospyros blancoi A. DC. extract inhibits the generation of NO and PGE2 which rapidly increases due to the induction of inflammation, which suppresses the transfer of NF-?B into a nucleus, thereby inhibiting the expression of iNOS and COX-2 and remarkably reducing the amounts of TNF-a, IL-1ß, IL-4 and IL-13. In addition, the Diospyros blancoi A. DC. extract inhibits eosinophilia in bronchoalveolar lavage fluid in the ovalbumin-induced asthma mouse model and inhibits the secretion of immunoglobulins and chemokines in bronchoalveolar lavage fluid and blood. Therefore, the Diospyros blancoi A. DC. extract can be beneficially used as an active ingredient for compositions used for preventing or treating inflammatory diseases, allergic diseases or asthma.

摘要:
The present invention relates to an assay system for quantifying Smad activity using a cell line that expresses a Smad transcriptional activity-dependent reporter gene, and the uses thereof, more particularly, an expression vector comprising i) a DNA fragment having repeating SBEs (Smad Binding Element), ii) a lucif erase gene as a transcription reporter, and iii) a selection marker gene; a transfectant transfected with the expression vector; and a method of screening anti-fibrotic agents, anti-cancer agents, or anti-inflammatory agents using the transfectant.
摘要:
The present invention relates to a composition comprising an extract of Tiarella polyphylla, and tiarellic acid isolated therefrom having anti-inflammatory, anti-allergic and anti-asthmatic activity. The extract of Tiarella polyphylla and the tiarellic acid isolated therefrom shows the inhibitory effect on the LTC 4 release in vitro test and the suppressive effect on the IgE level and the cytokine(IL-4, IL-5 and IL- 13) production, airway hyperresponsiveness, and leukocyte infiltration in OVA-induced asthmatic mice. Therefore, it can be used as the therapeutics or functional health food for treating and preventing inflammatory, allergic and asthmatic disease.

The present invention relates to a composition comprising an extract of Pseudolysimachion genus plant, and the catalpol derivatives isolated therefrom having anti-inflammatory, antiallergic and anti-asthmatic activity. The extractof Pseudolysimachion genus plantand the catalpol derivatives isolated therefrom shows potent suppressing effect on elevated IgE, IL-4 and IL- 13 levels and eosinophilia in the plasma and BALF, and mucus overproduction in the lung tissues in an OVA-induced asthmatic mouse model. Therefore, it can be used as the therapeutics or functional health food for treating and preventing inflammatory, allergic and asthmatic disease.

The present invention relates to an anti-aging composition containingan Elaeocarpus petiolatus extract or a fraction thereof as active ingredients, and more specifically an Elaeocarpus petiolatus extract or a fraction thereof of the invention exhibits a DPPH free radical removal effect and an ABTS free radical removal effect in a concentration-dependent manner in addition to a remarkable superoxide radical removal effect, thereby ensuring an excellent anti-oxidation effect. Therefore, the Elaeocarpus petiolatus extract or the fraction thereof is useful as active ingredients for anti-aging cosmetic compositions, pharmaceutical compositions, and health foods
摘要:
The present invention relates to a composition comprising Wercklea insignis extracts and fractions thereof for preventing and treating inflammatory diseases or asthma. The Wercklea insignis extracts and fractions thereof according to the present invention inhibit the generation of NO and PGE2 TNF-a which are rapidly increased by the artificial induction of inflammation in macrophages, inhibit the expression of iNOS and COX-2, inhibit MAPK protein phosphorylation, inhibit the nuclear transfer of NF-? ?, and reduce the quantities of cytokines IL-6 and IL-1beta, thereby inhibiting inflammation, inhibiting podedema in a carrageenan-induced mouse model, and significantly reducing the quantities of Th2-type cytokines IL-4 and IL-13 which increase in asthma or allergy. Therefore, the Wercklea insignis extracts and fractions thereof according to the present invention may be valuably used in a composition which is intended for medicine or health-promoting foods and which may require the Wercklea insignis extracts and fractions thereof as active ingredients for preventing and treating inflammatory diseases, allergies, and asthma.
