[The specific features of coronary artery lesion in patients with signs of high cardiac risk in non-ST segment elevation acute coronary syndrome].

The paper covers risk stratification for cardiac events in patients with non-ST segment elevation acute coronary syndrome. It defines an association between risk factors, the specific features of coronary artery lesions, and the outcomes of the disease in relation to the used treatment policy. Particular emphasis is laid on the factors that are a handicap to the detection of a symptom-associated coronary artery in this category of patients.

[Factors that cause a change in the antigenic structure of of the influenza virus hemagglutinin].

Crossing of norakin-resistant mutant NR1 of A/Waybridge (H7N7) strain of fowl plague virus (FPV) with human influenza virus strains produced recombinants inheriting the hemagglutinin (HA) gene of the NR1 mutant and neuraminidase (NA) genes of human influenza virus strains. The R120 recombinant produced by crossing of NR1 with A/Taiwan/1/86 (H1N1) strain, unlike other recombinants and NR1 mutant, lost the capacity of reacting in H1 test with two monoclonal antibodies (MCA) to HA7: 71/4 and 46/6. The ts mutant A/FPV/Rostok which has ts-mutation in HA-gene also had changes in the antigenic specificity of HA.

[Coagulation of experimental gunshot wounds of the liver and spleen using plasma argon flow].

Experiments were conducted on 26 dogs to study the possibility of debridement of gunshot wounds of the liver and spleen with plasma argon flow. The method was found to be highly effective in providing final hemo- and cholestasis. The elaborated ++plasma coagulation method allows organ-preserving operations to be undertaken and may be recommended for use in field surgery.
