Animals in the IR and IPC groups underwent 30 min of intestinal ischaemia followed by 2 h of reperfusion. In the IPC group this was preceded by 10 min of ischaemia and 10 min of reperfusion. Animals in the third group underwent laparotomy but no vascular occlusion. Intestinal microvascular perfusion, oxygenation and portal venous blood flow (PVF) were monitored continuously. At the end of the reperfusion period, blood samples were obtained for measurement of lactate dehydrogenase (LDH) and biopsies of ileum for histological evaluation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>IPC improved intestinal microvascular perfusion and tissue oxygenation significantly at the end of the reperfusion period (P &amp;lt; 0\u00b7001). PVF improved significantly in the IPC compared with the IR group (P = 0\u00b7005). The serum LDH concentration was significantly lower in the IPC than the IR group (mean(s.e.m.) 667\u00b71(86\u00b78) versus 1973\u00b78(306\u00b75) U\/l; P &amp;lt; 0\u00b7001) Histological
