NON-activated protein C as post-treatment after spinal cord compression injury in rats

Background. Neuroprotective effects of recombinant human activated Protein C (rhAPC) in models of Spinal Cord Injury (SCI) and ischemic stroke have been reported in rodents. To rule out immunogenicity of rhAPC and to possibly maintain the physiological PC/thrombin balance the use of zymogen PC in SCI might be preferable. Although activation of Protein C (PC) has been demonstrated in rats, the efficacy and drug safety of NON activated PC has not been previously tested in experimental SCI.
