[Electron microscopic studies of experimental staphylococcal infections in mice as chemotherapeutic models].

Study of ultrastructural changes in the brain and renal tissues has shown that both intracerebral and intraperitoneal administration of staphylococcus in low infecting doses leads to the development in the brain and renal tissues of acute purulent inflammation, with a dramatic growth of infectious process and involvement of all parts of the organs under consideration. The presence in the brain tissues and in its meninges of inflammatory pyonecrotic foci might attest to the necrotic purulent encephalomeningitis, whereas the presence in the cortex and renal medullary substance of histiolymphocytic infiltration and foci of necrosis might be evidence of necrotic glomerulonephritis of bacterial etiology.

[Structural changes in renal tissue in experimental staphylococcal septicopyemia].

The structure of the kidney tissue in mice with staphylococcal septicopyemia due to intraperitoneal introduction of Staph. aureus in various doses was studied. It was found that the level of acute purulent inflammation in the kidney tissue was different depending on the site of the affection: the purulent component predominated in the cortical layer, while the necrotic component in the medullary layer and papillae.

[Electron microscopic study of the antiviral action of bonafton in experimental influenza infection].

Action of bonaphthon on influenza A virus was studied in experimental influenzal pneumonia of mice. Bonaphthon was shown to lower 1.5-2 fold the reproduction of influenza virus in pulmonary tissue as compared with control.
