[Postmortem diagnosis of ventricular fibrillation in acute coronary insufficiency].

Occlusion of coronary artery in dogs has revealed differences in K and Na postmortal distributions in the heart and skeletal muscles after ventricular fibrillation and acute coronary insufficiency. A more dramatic reduction of K and Na content in the heart and skeletal muscles was noted in death caused by heart failure than death caused by ventricular fibrillation. The analysis of autopsy samples showed a more marked reduction in K content in a possible ischemic area (the middle third of anterior wall of the left ventricle) during slow death with short agonal periods as compared to sudden death and a significant reduction of K content in skeletal muscle during slow death in contrast to the absence of changes in sudden death.

[Experiment in infecting the green monkey Cercopithecus aethiops with a leukocyte virus isolated in hepatitis A].

The virus isolated in hepatitis A had been previously shown to passage in primary phytohemagglutinin-stimulated leukocyte cultures. The virus designated as leukocyte hepatitis virus (LHV) causes chromosome aberrations in the infected cultures. Some physico-chemical properties of LHV and its capacity for reproduction in other cell systems were studied.

[Effect of antihepatocytotoxic serum on processes of cellular and intracellular regeneration of pathologically altered liver].

The parameters of the liver regeneration: mitotic index, DNA synthesis, nucleolar size of hepatocytes and histological structure, were studied in adult female rats with CCl4-affected liver during administration of the gamma-globulin fraction of antihepatocytotoxic serum (gamma-AHCS). It was shown that in various periods after exposure to CCl4 either the cellular processes of regeneration are predominant or the intracellular ones. gamma-AHCS (0.
