[Discussion of the immunomorphological role of interactions between mast cells and in the gastric mucosa].

Helicobacter pylori induced gastritis accounts for 70% of cases in the structure of this pathology. Features of the long-term inflammatory reaction of the mucous membrane are directly related to the mechanisms of bacterial pathogenicity, and features of immunogenesis within narrow limits of the specific tissue microenvironment of organ structures. Mast cells appear to be one of the key players (promoters) in the regulation of the inflammatory mediator cascade and the formation of cytokine-induced expression.

Combined histochemical approach in assessing tryptase expression in the mast cell population.

To increase the efficiency of interpretation of mast cell's contribution to the state of a specific tissue microenvironment, it is necessary to detail the molecular composition of their secretome and analyze the pathways of degranulation. Developed method of combining immunomorphological and histochemical staining protocols contributes to the most objective detection of the integral level of tryptase expression in the intraorgan population of the skin mast cells. Novel technique for tryptase detection expands the possibilities of morphological analysis, provides researchers with additional data on the structure of the mast cell population and helps visualize the processing and cytological features and structural targets of tryptase during the development of adaptive and pathological reactions.

Essential hypertension and psychoneurologic state of civil aviation pilots.

Tests helped to evaluate psychoneurologic state in civil aviation pilots with various stages and grades of essential hypertension. Findings are that increase of essential hypertension intensity from borderline stage to 1 stage 2 grade reliably influences psychoneurologic state of pilots. Worsening was seen for parameters of volitional attention and spatial representation (test <>), ability to operate spatiel representations (test <>), ability to extrapolate, rapid sensomotor reaction (test <>), accuracy of dynamic eye assessment and balance of main nervous processes in visual analyzer (test <>).
