    Notes: Summary Twenty-two strains of influenza A virus were isolated from caged birds which had been imported into Japan from India and Thailand and had died during transportation to Tokyo. Serological tests divided these strains into two groups. Viruses in the first group contained Hav7 hemagglutinin and were related antigenically to A/duck/ Ukraine/1/63 [Hav7 Neq2]; viruses in the second group contained Hav4 hemagglutinin and were related to A/duck/Czech/56 (Hav4 Nav1]. All strains contained Neq2 neuraminidase that was closely related to that of A/equine/Miami/1/63 [Heq2 Neq2] and A/duck/Ukraine/1/63 [Hav7 Neq2]. It was concluded that the strains in the first group were Hav7 Neq2 and those in the second group were Hav4 Neq2; both groups of viruses showed antigenic drift from the prototype strains.

    Notes: Summary Influenza C viruses did not possess neuraminidase activity when examined using either fetuin or sialyllactose as substrate. Purified preparations of influenza C virus inhibited hemagglutination by NWS hemagglutinin. The hemagglutination inhibiting activity was a bolished by treatment of influenza C virus with neuraminidase. These findings indicated the absence of neuraminidase activity on influenza C virus particles.

    Notes: Summary Blood circulation in guinea pig cochlea was studied using a new “Ultraparc”-microscope with especially intensive light source and long-distance focus. Alterations after application of ephedrinelike substances were observed. We assume that there are alpha- and beta-adrenergic receptors within cochlea vessels, that noradrenaline produces vascular disturbance of the cochlea vessels and that after administration of isoproterenol an vasodilating effect could be shown.
