Abstract

Two control dogs and 2 dogs that had globoid cell leukodystrophy (GLD) were studied to document vascular alterations associated with the leukodystrophic lesion. Spinal white matter was sampled by transverse and frontal planes of section from dorsal and ventral halves of the lateral funiculus of five spinal segments. Vessel profiles were classified as capillaries or larger vessels. GLD lesion was associated with an increase in capillary mean diameter. Vascular density, estimated by profiles per area, was compared in affected and control tissues. Capillary density was not significantly different, but the density of larger vessels was increased in proportion to the extent of GLD lesion. The increased density is presumed to be the result of lengthening or proliferation of vessels which had normal density prior to lesion formation.
