Key result
Dimethyl sulphoxide demonstrated moderate clinical and electrophysiological effects in rats with spinal cord injury, whereas naloxone improved electrophysiological outcomes without clinical effect.
Why the study?
Do methyl prednisolone, dimethyl sulphoxide, or naloxone improve electrophysiological or motor outcomes in rats with experimental spinal cord injuries?

In a rat model of spinal cord injury, DMSO provides moderate clinical and electrophysiological benefits, whereas naloxone improves only electrophysiological parameters.

Rat SCI findings on DMSO and naloxone are hypothesis-generating; further studies needed before clinical consideration.
The effects of methyl prednisolone (MPD), dimethyl sulphoxide (DMSO), and naloxone were examined in 38 albino rats after making an impact spinal cord injury on the midthoracic segments with a modified Allen's weight dropping trauma method. Somatosensorial evoked potentials (SEPs) were recorded before and 12 h and 14 d after the injury from epidurally inserted electrodes on the parietal cortex with sciatic nerve stimulations. Lower extremity motor functions of the animals were also examined. It may be concluded that in this study model, DMSO has a moderate effect which can be demonstrated clinically and through SEPs. Naloxone has no effect on the clinical outcome but causes reasonable improvement electrophysiologically.

Zileli et al. (1988) studied experimental spinal cord injuries (n=38). methyl prednisolone, dimethyl sulphoxide, and naloxone was evaluated on Somatosensorial evoked potentials (SEPs) and lower extremity motor functions. Dimethyl sulphoxide demonstrated moderate clinical and electrophysiological effects in rats with spinal cord injury, whereas naloxone improved electrophysiological outcomes without clinical effect.
