【摘要】 目的　研究中药辛夷二氯甲烷提取物的药理作用。方法　采用体外、体内多种动物模型对辛夷二氯甲烷提取物进行了抗炎、抗过敏方面的研究。结果　辛夷二氯甲烷提取物对组胺 (HA )、乙酰胆碱 (Ach)引起的豚鼠离体回肠收缩具有显著的抑制作用 ,并能抑制卵白蛋白 (OA)所致的豚鼠离体回肠过敏性收缩 ,对 HAc引起的小鼠腹腔毛细血管通透性增高具有抑制作用 ,能显著抑制角叉菜胶引起的小鼠足肿胀 ,并减少前列腺素 E2 (PGE2 )在炎症组织中产生。结论　辛夷二氯甲烷提取物具有明显的抗炎、抗过敏作用。更多还原

【Abstract】 Object To study the pharmacological effects of CH 2Cl 2 extract of Flos Magnoliae.Methods Anti inflammatory and antiallergic effects of CH 2Cl 2 extract of Flos Magnoliae were studied on various experimental models. Results The extract remarkably inhibited the contraction caused by histamine and acetylcholine, as well as the ovalbumin sensitized allergic constriction of isolated ileum smooth muscle of guinea pigs. It could inhibit the increase of capillary permeability induced by acetic acid in mice, inhibit the mice paw edema produced by carrageenin and reduce the production of PGE 2 in inflammatory tissues. Conclusion CH 2Cl 2 extract of Flos Magnoliae showed remarkable anti inflammatory and antiallergic effects.更多还原
