Abstract:
AIM: The influence of the seawater on the lipid peroxidation of the muscle tissue wounded by firearm was studied. METHODS: Both two limbs of rabbits were wounded by the steel ball of 250 mg. The wounded rabbits were divided into two group: One is seawater immersed group (SIG), which was dipped in artificial seawater for 30 min. Another is the single wounded group (SWG), which wasn't dipped in seawater. Then, muscle tissues 0.5 cm (A area), 1.5 cm (B area) and 2.5 cm (C area) from wound edge were cut for biochemical analysis at 3, 6, 12, 24 h of post-wound, respectively. The contents of ATP, MDA and SOD activity of all these tissues were detected, pre-wounded muscle tissues were used as control group. RESULTS: The content of MDA in SIG increased obviously at 3, 6 h, respectively, but it decreased slightly at 12 h and increased again at 24 h. The change in MDA in SWG is similar to that in SIG but more slightly. The changes in both the activity of SOD and the content of ATP in two groups is similar to that of MDA. CONCLUSION: Seawater induced more serious lipid peroxidation in the muscle tissue wounded by firearm.
