RESUMO
Controlled compressive injury to rat spinal cord was chosen to test therapies that might attenuate the progression of tissue destruction and locomotor deficits that characteristically occur after spinal injury. A highly significant reduction of damage was achieved by immediate postinjury treatment with a combination of the following: an antiinflammatory substance, indomethacin; a stimulator of cytokine secretion, bacterial lipopolysaccharide; and the parent steroid, from which all other steroids arise, pregnenolone. This treatment reduced histopathological changes, spared tissue from secondary injury, and increased restoration of motor function. Remarkably, 11 of 16 of the animals treated with the above combination were able to stand and walk at 21 days after injury, 4 of them almost normally. The results were far superior to those obtained in controls or in animals to which the substances were given separately or in combination of two. This approach may prove to be applicable to nervous system injury, in general, and to injury in other tissues.
