[The morphogenesis of polyps of the large intestine].

The proportion of so-called hyperplastic polyps among other colon epithelial tumours remains unclear. Colon polyps are studied in 400 patients: hyperplastic polyps are found in 107, a combination of hyperplastic polyp with tubular adenoma in 143, tubular adenoma in 72, villous adenoma in 41 and tubulovillous adenoma in 37 cases. Hyperplastic structures and formation of adenomatous structures were, as a rule, observed in a polyp tip, this corresponding to the increase of nuclei volume and DNA amount in the tip colonocytes. The determination of karyometric coefficient (the ratio of the colonocyte nuclei volume in the polyp tip to colonocytes in the intact mucosa) is proposed as a quantitative criterion of proliferative and dysplastic processes.

[Effect of the surgical treatment of duodenal ulcer on the immune status].

Under examination there were 51 patients with duodenal ulcer with the terms of 6 and 12 months after various methods of operations on the stomach. An analysis of results has shown that the alterations of the immune system found are dependent on the kind of operation. In patients with duodenal ulcer with the terms of 6 and 12 months immune insufficiency remains the same. It is less pronounced in patients subjected to organ-preserving operations with vagotomy. The immunocorrective therapy performed at the preoperative period results in the formation of more valuable immune reactions at remote terms after operation.
