title: Glycine levels in the degenerated human spinal cord.
abstract: Tissues from non-degenerated tissue of 18 patients were assayed for glycine concentration in grey and white matter in the thoracic, cervical and lumbar regions. Confirming earlier results, glycine concentration was found to be maximal in the grey matter of the lumbar segments of the lateral column. Analysis of tissue from 11 human spinal cords showing unilateral Wallerian degeneration, 4 cords with amyotrophic sclerosis and 4 cords with bilateral Wallerian degeneration failed to show statistically significant differences when compared with control values. The results argue against a supraspinal origin of glycine and suggest that glycine levels are regulated locally or at a segmental level in the spinal cord in man.
