On the collection of 35 people with ureterosigmoidostomy analyse the authors advantages and disadvantages of these operation. Suitable indicated operation can give to the patients good hygienical amenities, continention of stool and urinae give him full sociability. Nondesirable consequences of connection between urinary and intestinal tract can be influated by optimal medication. The authors detaily described operation technique with their modification and indication.

In resected portions of the stomach we find chronic atrophic gastritis of the corpus only in 10% of the patients with duodenal ulcers, and chronic inflammatory changes are, contrary to patients with a gastric ulcer, less marked. The difference is statistically significant. Consistent with some other authors, we find that great progression of chronic inflammatory changes occurs in patients operated on account of duodenal ulcers in the course of the first three years after operation. From six cases of regression of chronic inflammatory changes after operation, in two cases undetected atrophic gastritis was involved which was present in a severe form in the body of the resected portion beyond the vicinity of the gastric ulcer. According to the author's findings regression of atrophic gastritis is possible. The high score of chronic inflammatory changes in the antrum of gastric resectates (3.54) and in the close vicinity of gastric ulcers (4.0) confirms the frequency of severe antral gastritis in peptic ulceration and the intensity of the focal inflammation in the vicinity of gastric ulcers.

The pregnancy diagnosis in sows using direct radioimmunoassay of estrone-sulphate in the blood serum without sample extraction is described. It was found that for the pregnancy diagnosis the period between days 22 and 30 of pregnancy can be used since in this period the estrone-sulphate concentrations in all pregnant sows markedly exceeded those of 64 non-pregnant animals. The estrone-sulphate estimation cannot be used for the pregnancy diagnosis before day 22 and between day 30 and 40 because the estrone-sulphate concentrations in most samples collected in these periods were lower than 4 nmol.l-1.

Endocrine adenomatosis of Langerhan's islets (gastrinoma), parathyroid, pituitary gland and adrenals manifested itself at a proband by Zollinger-Ellison syndrome and perhaps hyperparathyroidism. Proband late brother's autopsy was reviewed and a similar morphology was found with Cushing's syndrome and peptic ulcer. Both brethren's mother died from a complication of recurring peptic ulcer.
