Fig. 11From: Neoboutonia melleri var velutina Prain: in vitro and in vivo hepatoprotective effects of the aqueous stem bark extract on acute hepatitis modelsHistological changes in Concanavalin A-intoxicated mice. Animals were pretreated with either NVH extract or methylprednisolone during 3 consecutive days and acute liver injury was immediately induced with Concanavalin A intravenous injection after the last treatment. All animals were sacrificed 8 h after Concanavalin A injection. Liver sections were fixed and paraffin-embedded before haematoxylin-eosin staining. CTR: Control mice with normal liver structure; ConA: Concanavalin A treated mice with a damaged liver; ConA+NVH (15 and 75): Concanavalin A and extract treated mice with some persistent necrotic areas; ConA+MP: Concanavalin A and methylprednisolone treated mice without lesions. NVH: Neoboutonia velutina aqueous extract; MP: Methylprednisolone; ConA: Concanavalin A; CV: centrilobular vein; L: necrotic area. HEx100Back to article page
