Recommended irradiation dose and time window of local x-ray for spinal cord injury

The glial scar is the main inhibitor of axon regeneration and functional recovery in the central nervous system.

Appropriate dose X-ray irradiation has been shown to inhibit the formation of glial cells, thereby promoting axonal regeneration.

In addition, X-rays militate against the death and degeneration of neurons, and improve the recovery of locomotor function following . However, the optimal treatment time window and dose of X-irradiation for is still unknown.

Prof. and colleagues from have verified that X-irradiation at a dose of 8 Gy can inhibit at the injury site and alleviate the inflammatory reaction; day 7 post injury may be the optimal time window for topical X-irradiation.

These findings were published in the (Vol. 8, No. 17, 2013).
