Abstract: Abstract: Objective To study the influences of lipid peroxidation and antioxidant capacity of organism for traumatic． Method Choose 11 new zealand rabbits on ordinary level were collected blood samples，bilateral ear edge venules repeated puncture after collecting，every other day，2—3 times in a row，form animal model of trauma，blood samples were taken after the completion of the animal model，to detection serum malondialdehyde ( MDA) ，superoxide dismutase( SOD) ，hydrogen peroxide enzyme( CAT) ，glutathione oxidation reductase( GSHPx) ，total antioxidant capacity ( T-AOC) of the two groups before and after the build animal model，and be statistical analysis． Ｒesult MDA: A group ( 3. 048 ± 1. 259) ，B group( 3. 251 ± 1. 695) ，Group A less than in group B; T-SOD: A group ( 384. 314 ± 50. 122) ，B group ( 348. 942 ± 45. 852) ，A group higher than group B; CAT: A group ( 6. 121 ± 4. 097) ，B group ( 4. 563 ± 2. 223) ，A group higher than group B; GSH-Px: A group ( 377. 808 ± 72. 726) ，B group ( 349. 942 ± 54. 021) ，A group higher than group B; T-AOC: A group ( 5. 537 ± 2. 128) ，B group ( 4. 633 ± 2. 074) ，A group higher than group B; there were no statistically significant difference between the groups( P ＞ 0. 05) ． Conclusion There was certain influence to the lipid peroxidation and antioxidant capacity of organism for trauma ，and there was no significant influence．
