However, growing evidence suggests that epilepsy also impacts peripheral organs, including the gastrointestinal tract. The intestinal barrier, essential for maintaining homeostasis and immune defense, is particularly susceptible to oxidative stress, which can disrupt junctional proteins, leading to increased permeability and barrier dysfunction. This study aimed to investigate the effects of epilepsy on duodenal morphology and intercellular junction integrity, as well as to evaluate the potential protective role of\n                      <jats:styled-content style=\"fixed-case\">\n                        <jats:italic>Rosa Canina<\/jats:italic>\n                      <\/jats:styled-content>\n                      Seed Oil (RSO) in mitigating these alterations.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A pilocarpine\u2010induced rat model of epilepsy was employed in 47 male Sprague\u2013Dawley rats, randomly assigned to eight experimental groups, and treated intragastrically with\n                      <jats:styled-content style=\"fixed-case\">\n                        <jats:italic>Rosa canina<\/jats:italic>\n                      <\/jats:styled-content>\n                      seed oil (RSO) at doses of 0.125, 0.25, or 0.5\u2009mL\/rat\/day prior to epilepsy induction. Histomorphometric analysis was conducted to assess villus height, crypt depth, and mucosal surface area. Immunohistochemical staining was used to evaluate the expressions of key junctional and cytoskeletal proteins, including zonula occludens\u20101 (ZO\u20101), E\u2010cadherin, and vimentin.

RSO treatment demonstrated a dose\u2010dependent protective effect, with moderate and high doses partially restoring intestinal morphology and tight junction integrity. Notably, higher doses of RSO significantly restored ZO\u20101 levels and preserved vimentin expression, suggesting its role in stabilizing the epithelial barrier and cytoskeletal framework.
