[The virulence and antibiotic resistance of Escherichia isolated from man].

The virulence and antibiotic resistance of the same 75 strains of pathogenic Escherichia (PE) has been studied. Simultaneous determination of virulence in three tests (keratoconjuctival, intranasal and with the infection of cell culture) has permitted increasing detection of virulence strains to 97.4%.

[Effect of hypokinesia and physical loading on the ultrastructure of cardiac myocytes].

The experiments were carried out in rabbits and rats during 1--7.5 months. They demonstrated increasing disturbances in ultrastructure of the protein synthesizing myocardiocyte apparatus.
