[A decrease in the activity of the nucleolar organizers of the gastric and duodenal mucosal cells in peptic ulcer patients]. / Snizhenie aktivnosti iadryshkovykh organizatorov kletok slizistoi obolochki zheludka i dvenadtsatiperstnoi kishki bol'nykh iazvennoi bolezn'iu.

Silver plating of nucleoli was used to study the activity of nucleolar organizers (NO) in the cells of one-layer prismatic epithelium of the gastric and duodenal mucosae. The activity of NO was established to be lowered in patients suffering from ulcer disease and in patients with compression stenosis of the celiac trunk, which may point to the impairment of protein synthetic processes in the cells. Factor of ischemia as the most probable cause of the enumerated changes is under discussion.

[Blood flow in the gastric and duodenal mucosa in peptic ulcer]. / Krovotok v slizistoi obolochke zheludka i dvenadtsatiperstnoi kishki pri iazvennoi bolezni.

By means of a polarographic method, the decrease in the rate of blood flow in the gastric and duodenal mucosa at the period of exacerbation of ulcer disease, and its normalization at the period of ulcer healing were revealed. The role of the impaired blood supply of the mucosa in ulcer formation is discussed.
