Effects of sodium salicylate on epithelial cells of the rectal mucosa of the rat: a light and electron microscopic study.

Abstract:

:Using a ligation method, rat rectal epithelium was exposed to 2% sodium salicylate, and light and electron microscopic methods were used to assay for: 1) permeability of the epithelium to a marker dye, trypan blue, and 2) damage expressed in terms of disruption of the epithelial surface. Rectal mucosa was exposed to salicylate at pH 4.8, 7.0, and 9.0, and the effects of pretreatment with phlorizin were also studied. Results indicated that 2% sodium salicylate does very little damage to rectal epithelial cells at pH 7.0 while enhancing their permeability to trypan blue, an effect that is reversed upon washing out the sodium salicylate. The major cellular change induced by salicylate was a reduction in the length or distribution of glycocalyx filaments on microvilli of epithelial cells. It was also noted that pretreatment with phlorizin counteracted some of the effects of salicylate treatment.
