[Patient age and CYP2D6*4/CYP2D6*3 genotype on maximal heart rate in patients after acute coronary syndrome treated with bisoprolol.].

We have analyzed influence of genetic variants CYP2D6*3 (2549delA) and CYP2D6*4 (1846G>A), as well as other factors on effects of bisoprolol in patients with acute coronary syndrome. The study included 97 patients with acute coronary syndrome. Mean age was 63±10 years; 60 men and 37 women.

[Isolation of influenza A viruses with a new antigenic formula from wild birds].

Three hemagglutinating agents were isolated from mixed pools of the viscera from black-headed gulls (Larus ridibundus) and robin (Erithacus rubecula) collected in the Byelorussian SSA and the Kaliningrad region of the RSFSR. Typing of the viruses by double immunodiffusion technique revealed antigenic relationships of the viruses with swine hemagglutinin (Hsw1) and human hemagglutinin H0. One of the strains had neuraminidase N2 the other two Nav2.
