Abstract:
Objective To investigate the dose response effects of Shenfu injection, an intravenous drug made from traditional Chinese herbs, on the ischemic spinal cord injury in rabbits Methods New Zealand white rabbits were anesthetized with halothane and spinal cord ischemia was induced with 20 min infrarenal aortic occlusion Animals were randomly allocated to 4 groups, in group A(n=6) without pharmacologic intervention, in group B (n=6) ,group C (n=6) and group D (n=6) Shenfu injection 5,10 and 20ml?kg -1 were infused intravenously at a constant rate within 30min before the aortic cross clamping, respectively Neurologic status was scored by the Tarlov system 1,4,8,12,24 and 48h following reperfusion The animals were sacrificed 48h following reperfusion to sample the spinal cord (L5 7) immediately for histopathologic study Results All animals survived during the experiment Compared with that in group A, the neurologic deficit score (NDS) increased significantly at each observing time in group B, group C and group D (P0 05), but there was no significant difference between group B, C and D NDS in group A,B,C and D 48h after reperfusion were 0 5?0 8,3 2?0 9(P
