Investigate the effects of Argon laser irradiation on the cat's spinal dorsal column.
Evaluate the role of photoactivation in laser-induced spinal cord changes.
Assess the utility of S.E.P. in understanding Laser-Photo-Biological-Effects (L.P.B.E.).
Summary:
Unilateral Argon laser irradiation (500 mW, 2 mm spot size) of the cat's dorsal column caused disappearance of early S.E.P. components and histological destruction.
Fluorescein photoactivation with Argon laser in the spinal cord produced similar S.E.P. and histological results as non-fluorescein groups.
S.E.P. measurements proved effective in demonstrating Laser-Photo-Biological-Effects (L.P.B.E.) in the spinal cord.
Impact:
Provides evidence for localized tissue destruction by focused laser irradiation in the spinal cord.
Demonstrates the applicability of S.E.P. as a biomarker for laser-induced biological effects.
Contributes to understanding the mechanisms of laser-tissue interaction in neurological contexts.
