[Ultrastructure of the gastric mucosa in chronic renal failure].
Electromicroscopy (EM) findings of gastric mucosa from four patients with renal failure are reported. In these patients, the renal insufficiency appeared from different etiologies and ligth microscopy showed only corion edema. It was only through the EM studies that we could show great autophagic vacuoles in almost all surface epithelial cells; some of them, containing citoplasmic structure residues. In the four patients we found a remarkable activity of autophagocitosis. The autodestructive celular changes suggest two possibilities: a) the mucosal edema could obstruct a poorer nutrition of the tissues and/or b) It could represent a high flucagon activity.
