[Functional morphology of gastric mucosa in the syndrome of celiac artery stenosis before and after decompression].

Under study were morphological changes in the gastric mucosa in 40 patients with the syndrome of abdominal ischemia due to a varying degree of stenosis of the celiac artery, and in 8 patients without any changes in the celiac artery. In 10 cases the mucous membrane was studied histoenzymologically. In a marked stenosis of the celiac artery there was observed an atrophy of the mucosa and decreased general activity of succinate-, lactate, and NAD-N-dehydrogenases on account of a decreased number of cells, in which these enzymes are revealed. In early stages of the disease restoration of blood flow would result in normalization of the mucous membrane structure.
