RESUMO
The effects of septoplasty and sinus lifting simulation in rats on changes in the frequency domain of heart rate variability were compared. In the early postoperative period, the low-frequency component increases, and the high-frequency component decreases. The VLF range also increased. This indicates an increase in the activity of the sympathetic nervous system and a shift in metabolism under the influence of post-surgical inflammation.

Molecular masses of cholera bacteriophages 493, 7226 and Eltor II were defined by electron microscopic technique. DNA of these bacteriophages was digested by the restriction endonucleases PstI, BglI, MluI and SalI. The number and molecular masses of the obtained restricts were identified. The physical map of bacteriophage 493 was constructed using three restriction endonucleases. The obtained data can be used for classification and molecular biology research of cholera bacteriophages.

DNA-methyltransferases of Yersinia pestis EV, plague agent bacteria were isolated by P-II phosphocellulose chromatography. The methylating activity is eluated by two fractions at the 0.47 M and 0.53 M NaCl concentrations. Methylases of the plague microbe are specific with respect to two bases (adenine and cytosine) and are capable of modifying both native and denaturated form of DNA.
