Lansoprazole Improves Long-Term Neurological Function via Alleviating Intestinal Injury in a Mouse Model of Intracerebral Hemorrhage
Abstract
Intracerebral hemorrhage (ICH) can compromise the gastrointestinal tract and trigger intestinal injury, contributing to poor clinical outcomes. This study investigated the effects of lansoprazole on intestinal injury and neurological function in mice with ICH. Mice were stereotactically injected with collagenase to establish an ICH model. Neurological function, brain water content, blood-brain barrier permeability, intestinal injury, and intestinal permeability were evaluated. Levels of LPS and IL-1β in the blood and brain were also assayed. Lansoprazole treatment was associated with alleviated intestinal injury, reduced levels of LPS and IL-1β in blood and brain, decreased brain water content, and inhibited brain inflammation in ICH mice. While lansoprazole administration did not lead to improved performance in the Garcia, forelimb placing, and rotarod tests (short-term neurological function), it significantly enhanced learning and memory (long-term neurological function). These findings indicated that lansoprazole treatment was associated with improved long-term neurological outcomes and reduced intestinal injury in ICH mice.
