Design
Laboratory study
Subjects
Rats with spinal cord injury induced by a modified Allen's method; numbers not stated in the abstract
Dose used in the study
Palmitoylethanolamide; dose and route not stated in the abstract
Duration
Assessed at 1, 3 and 7 days after injury
What was measured
BBB locomotor scores; spinal cord histology; reactive oxygen species, acrylamide and MnSOD; NF-kappa-B, Bcl-2, BAX, PI3K/Akt, Nrf2, HO-1, TRX-1 and Raf-1/MEK/ERK proteins

What the authors reported

PEA reduced spinal cord injury in rats, inhibited inflammatory responses, reduced oxidative stress and apoptosis, and improved motor function recovery. It activated MEK and ERK phosphorylation, moved Nrf2 into the nucleus and raised HO-1 and TRX-1.

Limits of this study

A rat model of spinal cord injury; it cannot show effect in people. Dose, route and animal numbers are not in the abstract. The authors declare no conflicts of interest.
