[Ultrastructural changes of epitheliocytes and vessels of the small intestinal microcirculatory system in rabbit pups infected with cholera vibrions].

10-12 days old suckling rabbits-pups were infected by cholera vibrions of 01329 serogroup (16063 and M045 strains). Ultrastructural changes in small intestinal epitheliocytes and microcirculatory vessels were studied. Both strains caused typical cholerogenic syndrome, dystrophic and necrotic changes in epitheliocytes, epitheliocytes and lymphocytes, increase of vessel permeability, rheological disorders.

[Morphofunctional changes in the small intestinal mucosa in dynamics of physiological pregnancy and lactation].

Histostructural changes of small intestine mucosa of intact, pregnant and lactating rats were studied by optic and electron microscopy and morphometry. Increase of mucosa thickness, vili height, crypt depth, quantity of enterocytes and crypts were studied in dynamics of pregnancy. Period of lactation that followed labour was characterized by opposite processes, i.

[Lung tissue changes in experimentally induced inflammation and its treatment].

As a result of the investigation of experimental models of pneumonia, three stages of its development and peculiarities of epitheliostromal interrelations in walls of bronchi and in lung respiratory region characteristic for every stage were established. Administration of benzonal as an inductor of the surfactant system along with polyunsaturated fatty acids exerted stimulating effect on the adaptive processes at acute and subacute stages in pneumonia. The number of macrophages increased, their function enhanced, which, along with type II alveolocytes proliferation indicated the activation of regenerative processes.
