title: Anti-inflammatory and anti-angiogenic activities of Gastrodia elata Blume.
abstract: Gastrodia elata Blume rhizome has been traditionally used as a folk medicine for centuries in Oriental countries. Its ethanol extract (GEE) and subsequent fractions were used to evaluate anti-angiogenic, anti-inflammatory and related activities of Gastrodia elata. GEE potently inhibited angiogenesis in the chick chorioallantoic membrane assay, and its n-butanol fraction (BuOH) exerted the higher inhibitory effect. In a dose-dependent manner, GEE inhibited vascular permeability induced by acetic acid. GEE and its BuOH fraction exerted an inhibitory activity on exudate production, leukocyte migration and nitric oxide (NO) level in rat air-pouch model. GEE caused a dose-dependent inhibition of acetic acid-induced abdominal writhing in mice. In addition, GEE inhibited NO production and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) upon stimulation by lipopolysaccharide (LPS) in RAW264.7 macrophages. In summary, we demonstrate some novel pharmacological activities of Gastrodia elata, such as anti-angiogenic, anti-inflammatory and analgesic activities, and in vivo and in vitro inhibitory activity on NO production.
