BACKGROUND Radix Scutellariae, a few papers reported its pharmacology activities including alleviate small intestines smooth muscles spasm, sedation, antihypertensive effect. However, the inhibition of its different organic extracts on immediate hypersensitivity has not bee researched. MATERIALS AND METHODS To investigate the anti-immediate hypersensitivity of three extracts including ethanol...

BACKGROUND KHU14, an ethanolic extract of Radix Gentianae Macrophyllae (Qinjiao), Rhizoma Coptidis (Huanglian) and Citri Unshiu Pericarpium (Wenzhou migan) was tested for its anti-inflammatory effects. METHODS Three out of 20 herbs were found to have anti-inflammatory effects. The formulation of these herbs, i.e. KHU14 was tested for croton oil-induced ear edema, carrageenan-induced paw edema...

background & aim: eugenia caryophyllata well known as clove is a tree from myrtaceae family that several parts of this plant traditionally used in dental care as an analgesic. this study aimed to assess the chemical composition, anti-inflammatory and anti-nociceptive activities of the essential oil extracted from clove buds. experimental: the essential oil of clove buds (eoc) was extracted ...

Pharmacological blockade of N-acylethanolamine acid amidase (NAAA) activity is an available approach for inflammation and pain control through restoring the ability of endogenous PEA. But the recently reported NAAA inhibitors suffer from the chemical and biological unstable properties, which restrict functions of NAAA inhibition in vivo. It is still unrevealed whether systematic inhibition of N...

The marine product variabilin was identified as a novel inhibitor of phospholipase A2 (PLA2), which exhibited IC50 values of 6.9 microM and 7.9 microM for human synovial secretory PLA2 and U937 cells cytosolic PLA2 activities, respectively. This compound was less potent on bee venom or zymosan-injected rat air pouch enzymes and failed to affect Naja naja venom PLA2. The production of leukotrien...

Background: Through this work we evaluated the potential of the aqueous extract of Annona muricata L. leaves (AMAEL) to treat inflammatory conditions. The use of decoction or infusion of this important medicinal resource is still not scientifically validated. Methods: Different doses of AMAEL were assayed in carrageenan-induced inflammation and tetradecanoylphorbol acetate (TPA)-induced edema i...

Erigeron breviscapus (Vant.) Hand-mazz (EB), Erigeron multiradiatus (Lindl.) Benth (EM), and Aster brachytrichus Franch (AB), confused under the vernacular name "meiduoluomi" by native people and traditional healers, have been used for the treatment of meningitis, polyneuritis, hepatitis, adenolymphitis, and enteronitis in traditional Tibetan medicine. In this study, the antiinflammatory activi...

The methanolic extract of Myrsine seguinii yielded three anti-inflammatory compounds, myrsinoic acids B, C and F, and their structures were elucidated from the spectroscopic data. These compounds suppressed the TPA-induced edema of mouse ear, myrsinoic acid F being the most active (IE 77% at a dose of 0.56 micromol).

BACKGROUND Volatile oils obtained from lemon grass [Cymbopogon citratus (DC.) Stapf, Poaceae family] are used in traditional medicine as remedies for the treatment of various diseases. AIMS In the present study, lemon grass essential oil (LGEO) was evaluated for its in vivo topical and oral anti-inflammatory effects, and for its in vitro antifungal activity using both liquid and vapor phases....

To investigate the involvement of protease-activated receptor-2 (PAR-2) in allergic dermatitis, we generated PAR-2-deficient (PAR-2(-/-)) mice. Ear thickness, contact hypersensitivity (CH) induced by topical application of picryl chloride (PC) or oxazolone (Ox) after sensitization, and vascular permeability after ear passive cutaneous anaphylaxis (PCA) were compared between wild-type (WT) and P...
