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.

Anatomy of the Intestines
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
Small Intestine
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...
Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
