Abstract

BackgroundThe purpose of this study was to investigate the therapeutic effects and mechanisms of hyperbaric oxygen HBO treatment on rats following spinal cord injury SCI.

MethodsA total of 45 Sprague-Dawley SD rats were randomly divided into three groups. Sham-SCI group was surgically exposed but not subjected to the SCI procedure. SCI-control group was administered SCI and treated with regular air. SCI-HBO group was administered SCI and HBO treatment. Neuromotor functions were examined using the Basso, Beattie, and Bresnahan BBB locomotor rating scale and the inclined plane assessment at before SCI baseline and after SCI. Superoxide dismutase SOD activities and malondialdehyde MDA levels were measured.

ResultsStarting from Day 1 after SCI but except Day 2, the SCI-HBO group has significantly higher BBB scores than the SCI-control group. After SCI, the maximum inclination angles at which rats could maintain were significantly lower in both SCI groups. But the maximum angles were significantly bigger for the rats in the SCI-HBO group than those on the SCI-control group at 5, 10 and 20 days after SCI. SOD activities in SCI-HBO rats were significantly higher and MDA levels were significantly lower than in SCI-control rats, at two and five days after SCI. There was also less cystic degeneration of spinal cord in SCI-HBO rats, compared to SCI-control rats.

ConclusionsThese results suggest that HBO treatment has a therapeutic value in treating SCI. Increased oxygen free radical scavenging and reduced lipid oxidation may be one of the mechanisms.
