Increased endoneurial fluid pressure in galactose neuropathy

Abstract

Abstract Edema and increased endoneurial fluid pressure developed in peripheral nerves of rats that received a diet containing 40% galactose during a study of the role of sugar alcohols in producing neuropathy. Fluid pressure was elevated starting in the third month and progressed to a fivefold increase over control values by the fifth month. Microscopic examination confirmed the presence of edema as predicted by the sorbitol theory, which is often invoked to explain the pathogenesis of diabetic neuropathy.
