ABSTRACT
<p><b>AIM</b>To investigate the effect of paraventricular nucleus (PVN) stimulation and the c-fos expression within PVN and nucleus tractus solitarius (NTS) of the rat following gastric ischemia/reperfusion injury (GI/RI).</p><p><b>METHODS</b>The rat celiac artery was clamped for thirty minutes and reperfused for sixty minutes, using Fos immunohistochemical method (ABC method) examined the c-fos expression within PVN and NTS.</p><p><b>RESULTS</b>(1) Both electrical and chemical stimulation of the PVN obviously attenuated the GI/ RI. (2) Bilateral electrolytic lesion of NTS could eliminate the protective effect of electrical stimulation of the PVN. (3) The Fos-like immunoreactive neurons were increased in bilateral PVN and NTS by GI/RI.</p><p><b>CONCLUSION</b>The function of PVN and NTS could be affected by the GI/RI noxious stimulation. PVN, NTS were involved in the regulation of GI/RI.</p>
