[Chewing gum Dirol effect upon the status of oral cavity and gastric acid secretion in patients with hypersecretion of hydrochloric acid]. / Vliianie zhevatel'noi rezinki Dirol na pokazateli sostoianiia polosti rta i kislotoobrazuiushchuiu funktsiiu zheludka u bol'nykh s giperkhlorgidricheskim tipom sekretsii.

The purpose of our research was to learn the efficacy of the Dirol chewing gum upon the condition of the oral cavity and the stomach acidity in patients with hyperchlorhydratic type of secretion. It has been estimated that correct usage of chewing gum by patients with hyperacidity of the stomach in a month after its administration decreases the level of gastric acidity to a normal one. Thus, it has been proved that the Dirol chewing gum favorably changes the condition of oral cavity both from hygienic point of view, acido-alkaline balance and saliva condition.

[Plasma fibronectin in gastric and duodenal ulcer]. / Plazmennyi fibronektin pri iazvennoi bolezni zheludka i dvenadtsatiperstnoi kishki.

Solid phase enzyme immunoassay was made to measure fibronectin in blood plasma of 132 patients with ulcer and healthy controls. Exacerbations of ulcer occurred in a significant lowering of fibronectin concentration which tended to an increase with ulcer healing. In the scarring phase fibronectin levels returned to normal. A local stimulating action of a plasma fibronectin preparation on scarring of the ulcer defect is validated.
