Abstract [en]

The possibility of using the presence of the glial-cell-derived protein S-100 in serum as a marker for neuronal damage caused by spinal cord injury and plexus avulsion injury was investigated in 144 adult rats. After a spinal cord injury had been induced at the thoracic level or a plexus avulsion injury at the lumbar level, blood samples were taken and analysed for S-100 protein by a monoclonal two-site immunoluminometric assay. The two types of neurotrauma changed the kinetics of serum S-100 in different ways. After spinal cord injury it rapidly increased and within 72 hours had reached a concentration about 5 times that of the control animals. Three peak concentrations occurred at 3, 12, and 72 hours, respectively, and differed significantly from those of the control group (p < 0.05). After six days the values had returned to normal. After lumbar plexus injury alone there was no significant increase in the concentration of S-100. These results suggest that the concentration of S-100 protein in serum may be used as an early diagnostic tool for detecting neuronal damage caused by spinal cord injury or plexus avulsion associated with damage to the root entry zone.
