  • Title: Blood flow in normal and injured monkey spinal cord.
    Author: Bingham WG, Goldman H, Friedman SJ, Murphy S, Yashon D, Hunt WE.
    Journal: J Neurosurg; 1975 Aug; 43(2):162-71. PubMed ID: 1102630.
    Abstract:
    The authors used indicator fractionation techniques to determine blood flow in normal and bluntly traumatized spinal cords of Macaca rhesus monkeys. Normal flow rates were determined for several levels of spinal cord as well as differential values for white and gray matter from representative areas. Flow rates in traumatized tissue, obtained at several different time intervals up to 4 hours after injury, demonstrated marked differences in regional perfusion of the white matter and gray matter after trauma. Gray matter perfusion was nearly obliterated while white matter blood flow persisted and in fact was higher than uninjured controls. The findings do not support the concept of ischemia as a factor in white matter failure. If toxic pathobiochemical alterations are induced by trauma, it may be possible to reverse these changes by exploiting the preserved white matter blood flow for chemotherapeutic intervention.
