Abstract

This study investigated the neuroprotective efficacy of local hypothermia in a minipig model of spinal cord injury (SCI) induced by a computer‑controlled impactor device. The tissue integrity observed at the injury epicenter, and up to 3 cm cranially and caudally from the lesion site correlated with motor function. A computer‑controlled device produced contusion lesions at L3 level with two different degrees of tissue sparing, depending upon pre‑set impact parameters (8N‑ and 15N‑force impact). Hypothermia with cold (4˚C) saline or Dulbecco's modified Eagle's medium (DMEM)/F12 culture medium was applied 30 min after SCI (for 5 h) via a perfusion chamber (flow 2 ml/min). After saline hypothermia, the 8N‑SCI group achieved faster recovery of hind limb function and the ability to walk from one to three steps at nine weeks in comparison with non‑treated animals. Such improvements were not observed in saline‑treated animals subjected to more severe 15N‑SCI or in the group treated with DMEM/F12 medium. It was demonstrated that the tissue preservation in the cranial and caudal segments immediately adjacent to the lesion, and neurofilament protection in the lateral columns may be essential for modulation of the key spinal microcircuits leading to a functional outcome. Tissue sparing observed only in the caudal sections, even though significant, was not sufficient for functional improvement in the 15N‑SCI model.
