Anxiety, self-control and shooting performance.

55 rifle shooters were administered state-trait anxiety and self-control questionnaires. Shooting performance was recorded on 7 competitive occasions. Analysis indicated shooting performance is dependent more on anxiety state than on anxiety trait and self-control. Highly skilled shooters were less anxious and performed better across all competitions than moderately skilled shooters but did not differ on self-control and anxiety trait. The assumption that increased anxiety negatively affects performance through the mediation of self-control should be further studied.

Immunogenicity of inactivated influenza vaccine, purified by adsorption chromatography on porous glas.

A chromatographic process has been developed for a mass purification and concentration of influenza virus. The final virus suspension, purified some 400 times, is characterized by its antigenic properties and protein content. The virus was killed by UV-light and the resulting vaccine tried on 345 people. The immunity level is 8 times higher than the control. In mice which were infected after immunization with a homologous and heterologous influenza virus strains a high protection index was found (10(6) EID50 for homologous and 10(4) EID50 for heterologous strains).
