[Stimulation of adenosine receptors on myeloid cells enhance leukocyte migration at the site of burn injury].

Adenosine, endogenous purine nucleoside, is an ATP metabolite that also acts as an extracellular signaling molecule. The concentration of extracellular adenosine rises during hypoxia and cell damage leading to numerous pleiotropic effects. Although a high concentration of adenosine was found at burn injury, the effect has not been well elucidated.

[Cytomorphological analysis of remodeling of the bronchial wall in different types of bronchial asthma].

The objective of the present work was to search for the tissue and cellular markers of remodeling of bronchial mucosa in the patients with different clinical forms of bronchial asthma (BA). The use of up-to-date morphometric techniques has demonstrated that mild and moderately severe forms of bronchial asthma are accompanied by the development of Th2-immune response associated with increased production of interleukin-4 and marked degranulation of eosinophilic granulocytes resulting in desquamation of epithelium and goblet cell hyperplasia. The severe BA phenotype of "chronic asthma with fixed obstruction" is associated with the development of non-atopic inflammation in the bronchial mucous membrane that manifests itself as the increased concentration of interleukin-8 in bronchial mucosa and its neutrophilic infiltration leading to the development of pronounced subepithelial fibrosis, thickening of the basal membrane, and atrophy of epithelium.

[Liver, kidney and a lung structure in rats after intravenous magnetoliposome administration].

This work examines the effect of magnetoliposomes on the basis of Fe3O4 nanoparticles following different time intervals after their single intravenous injection, on the liver, kidney and lung structure in rats. Sections were stained with hematoxylin and eosin, and Perls method was used to demonstrate Fe+3 ions. It was shown that shortly after intravenous injection of magnetoliposomes, hemodynamic disturbances developed in all the organs studied, which by day 14 were aggrevated by focal necroses and dystrophic changes in the liver and kidneys.
