Table beet (<i>Beta vulgaris</i> L. var. <i>rubra</i>) contains bioactive agents, which have a wide range of different physiologic effects. These agents have beneficial antioxidant properties. The aim in the present study was to determine the gut protecting properties of bioactive substances of table beet in a model of ischaemic-reperfusion injury of the rat liver. Chemiluminescent intensity, H-donating ability, reducing power and free SH-group concentracion were determined by luminometry and spectrophotometry in duodenum and plasma. Lyophilized table beet increased significantly the free radical scavenging property of the plasma measured by chemiluminometry. Other antioxidant parameters of the plasma increased in rats fed table beet diet, and change in reducing power was significant. Beneficial effect of the treatment was found in changes of total scavenger capacity of the duodenum during ischaemia-reperfusion injury. H-donating ability and reducing power of the gut decreased in the table beet-fed group during ischaemia-reperfusion compared to normal group with ischaemia-reperfusion. Based on these data, it can be concluded that table beet can protect the entire body from the oxidative damage caused by ischaemia-reperfusion of the liver, but the effect of table beet treatment on gut mucosa needs further investigation.</p> <p class=MsoNormal> </p>
