METHODS: (1) 40% total body surface area (TBSA) Ⅲ° burn model was made in Wistar males rats. Brain water (%) was examined at 24 h after burn. (2) NE levels in the rat brain tissue were determined by high performence liquid chromatography. (3) VEGF protein levels in the rat brain tissue were determined by Western blotting at 24 h of postburn. RESULTS: (1) Brain edema exhibited at the burns and burn with norepinephrine groups. (2) A increase in NE levels in the rat brain tissue was observed at the burns. NE levels increased significantly in burn with norepinephrine groups. (3) VEGF protein expression in the rat brain tissue was gradually increased with increasing in norepinephrine stimulating dose. VEGF protein expression in the burn rats brain tissue was significantly increased in burn with high dose of norepinephrine stimulation. CONCLUSION: Norepinephrine induced VEGF protein expression in rat brain tissue at 24 h after severe burn, suggesting that increases in norepinephrine level postburn induce brain edema.Read More
