Abstract

Excessive activation of the greater splanchnic nerve (GSN) has previously been determined to contribute to the progression of gastric ischemia‑reperfusion (GI‑R) injury. The present study was designed to estimate the protective effects of GABAA receptor (GABAAR) overexpression in the lateral hypothalamic area (LHA) against GI‑R injury. The GI‑R injury model was induced in rats by clamping the celiac artery for 30 min and then reperfusing for 1 h. Microinjection of recombinant adenoviral vectors overexpressing GABAAR (Ad‑GABAAR) or control adenoviral vectors (Ad‑Con) into the LHA was conducted in GI‑R and normal control rats. Significant protective effects were observed on day 2 after Ad‑GABAAR treatment in the GI‑R injury rats. Ad‑GABAAR treatment reduced plasma norepinephrine levels, plasma angiotensin II levels and peripheral GSN activity, but increased the gastric mucosal blood flow, as compared with Ad‑Con treatment. These results indicate that adenoviral vector‑induced GABAAR overexpression in the LHA blunts GSN activity and subsequently alleviates the effects of gastric injury in GI‑R rats.
