To investigate the effects of Xingnaojing (XNJ) on the impairments of neurological functions and intestinal injury in Intracerebral Hemorrhage (ICH) mice. In vivo , mouse ICH model was prepared with stereotaxic injection of collagenase into the right basal ganglia. ICH mice were treated with XNJ (2.5, 5.0, 10.0 mL/kg intra-venous.). Garcia test and brain edema were evaluated. The lipopolysaccharide (LPS), TNF-α and IL-1β in both blood and brain were assayed using Enzyme-Linked Immunoassay (ELISA) kits. The intestinal injury was also observed. In vitro, the model of gut injury was established using lipopolysaccharide-challenged Colon Carcinoma-2 (Caco-2) cells. And intestinal injury was evaluated by assaying Transepithelial Electrical Resistance (TEER) and FITC-D4 flux. In vivo , ICH mice exhibited a decrease in Garcia test score and an increase in brain edema. ICH induced a damage of intestinal tissue and increases of LPS, TNF-α, IL-1β. XNJ significantly improved the parameters mentioned above. In vitro , LPS induced a decrease of TEER, an expression of occludin, and an increase of FITC-D4 flux. However, XNJ not only augmented the level of TEER, expression of occludin but also reduced FITC-D4 flux in LPS-challenged Caco-2 cells. This study demonstrated that XNJ improves neurological function in ICH mice, in which, attenuating intestinal injury and inhibiting LPS translocation and the inflammation may play an important role.
