[Glycoproteins of mucus of gastric and duodenal wall surface during ulcerogenesis and the impact of fenugreek].

The comparative evaluation of qualitative and quantitative composition of glycoproteins of gastric and duodenal wall surface layer of protective mucus in the normal, at the modeling of ulcers in rats and at the introduction to animals with ulcerative lesions of fenugreek extract carried out. It was shown in control (normally) the general level of glycosylation of glycoproteins gastric mucus is 1.7 times more than the duodenum.

[Participation of cyclic nucleotides and phospholipidis in signal transduction of histamin receptor H3 of the gastric mucosa parietal cells in rats with experimental ulcer].

The goal of the work was to evaluate plasma membrane phospholipid composition in rat gastric parietal cells under the histamine H3 receptor activation. The content of cyclic nucleotides was also studied. It was shown that H3-receptor agonist (R)-alpha-methylhistamine increases the phosphatidylcholine (PC) and phosphatidylethanolamine (PE) level and decreases the phoshatidylinositole level in plasma membrane of rat gastric parietal cells and leads to attenuation of the cGMP production and enhancement of the cAMP production under the experimental stress--the induced stomach ulcer formation.

[Growth characteristics of Lactobacillus plantarum, Bacillus subtilis and Bacillus licheniformis at deep cultivation in the monoculture and coculture].

Active growth of some representatives of bacteria of Bacillus genus on earlier optimized nutrient medium for L. plantarum 8R-A3 is shown. Growth characteristics of the studied bacteria at mixed cultivation on this medium have been studied.

[Culture media for growth and spore formation of Bacillus subtilis and Bacillus licheniformis].

The nutrient media for deep cultivation of Bacillus subtilis 3 and Bacillus licheniformis 31 have been optimized. It has been shown, that the media caused much higher biomass production from 2.0 x 10(10) CFU/ml media for B.

[Development of nutrient medium for the cultivation of Lactobacillus plantarum 8R-A3 ].

Optimal nutrient medium providing accumulation of cell biomass of Lactobacillus plantarum 8R-A3 has been developed. According to this index the proposed medium meets the nutrition requirements of bacteria under study and is comparable with the basal (MRS) medium. Dependence of growth properties of Lactobacillus plantarum 8R-A3 on concentration of the medium basal components has been studied.
