[The metabolic and structural changes in periodontal tissue in patients with hypothyroidism].

The bioptats of gingiva of 88 patients with different degree of periodontities on the background of hypothyreosis was studied. The histochemical and histoenzimochemical investigations were carried out. It was shown the decrease of fermental activity: mitochondrial breathing - oxydoreduqtases, glycolysis and in the same way terminal oxidation in the structures of ephythelial tissue and mucous membrane, especially in patients with middle severity periodontities.

[Vagotomy as a simultaneous intervention component in the treatment of duodenal ulcer].

For the 1970-1997 yrs. period 1357 patients were operated on for an ulcer disease using vagotomy, in 361 (26%) simultant operations were carried out, including in 340--for the abdominal cavity organs diseases and in 21--for intraoperative complications.

[Multi-layer musculo-aponeurotic repair in the treatment of patients with extensive median abdominal hernia].

A modified method for hernioplasty consisting in performance of multi-layer reconstruction of the abdominal wall with transfer and implantation of one of the cuspids of the hernial sac tissues beyond the contralateral musculus rectus abdominis has been suggested. Operated on were 20 patients with extensive, or giant abdominal hernia. Within 2 years after the operation, no hernia recurrence was noted.

[An experimental study of the mechanisms of damage of the periodontal tissues in thyrotoxicosis].

Morphologic studies of the periodontal tissue in rats have revealed that destruction of the maxillodental system in excess of thyroid hormones is explained by disordered mineral metabolism, resorbed osseous tissue of the alveolar process, energy shifts, and developed inflammatory process. Introduction of physiologically-based amounts of calcium, iodine, and fluorine in the animals' ration at the early stages of their development reduced the degree of the alveolar process osseous tissue resorption.
