In this study

the plasma and erythrocyte（RBC）lipoperoxidation rates

the contents of antioxidant vitamin E（VE）and the activities of antioxidationenzyme SeGSHP

x

of plasma and RBC in the patients with burn were determinedon the 1st

3rd

5th

10th and 15th days after burn.The results showed that ascompared with healthy subjects

the contents of Iipoperoxide were increased

and thelevels of VE and the activities of SeGSHP

x

were decreased significantly.Thechanges became more significant with the time elapsing

and the most significantchanges were on the 10tb days postburn.In the meantime the percentages of RBCspontaneous hemolysis and the activities of SeGSHPx were increased

and thecontents of VE in RBC were decreased markedly.The regularity of the changes inthe lipoperoxidation rates of plasma and RBC was in accordance with that in thecontents of VE in them.The degrees of the changes in the LPO and VE contentsand the SeGSHPx activities in plasma were in relation to the extents of burn.Onthe 53th

65th and 85th days during recovery postburn

the changes were stillsignificant compared to the healthy subjects

although they had a tendency torestore.
