Abstract:
Objective To investigate the effect of seawater immersion on the hemostatic function of endothelial cells in dogs sustained burn firearm combined injury and the mechanisms. Methods Dogs with burn firearm combined injury were randomly divided into two groups: immersion group and control group. Dogs in immersion group were immersed in seawater for 4 h, and then taken out from seawater. Blood samples were collected from central vein before wound, immediately after immersion, at 4, 7, 10, 20, and 28 h after immersion to detect the changes in circulating endothelial cells (CEC), tissue type plasminogen activator (t PA), plasminogen activator inhibitor (PAI), and thromboxane B 2/6 keto prostaglandin F 1? (TXB 2/6 K PGF 1? ). Dogs were sacrificed at 28 h after wound for the purpose of pathological examination of the lung tissue. The indices detected except seawater immersion in the control group were the same as those in the immersion group. Results In the control group, the levels of CEC, PAI 1, and TXB 2/6 K PGF 1? increased, but the level of t PA decreased at 4 and 7 h after wound. However, in immersion group, the levels of CEC, PAI 1 and TXB2/6 K PGF1? kept increasing, but the level of t PA kept decreasing at 4, 7, 10, 20, and 28 h. Each index in immersion group from 4 h to 28 h after wound was significantly different from that in the control group ( P
