[The humoral immunity indices of rhesus monkeys under the action of extreme factors in space flight].

Some features of nonspecific resistance of rhesus monkeys (G and A immunoglobulins and C3 complement component) are studied. Standards of IgG, IgA and C3 complement component in healthy rhesus monkeys are determined. The changes in the parameters of nonspecific resistance of the animals in all stages of their preflight training and shortly after flight experiment are examined. These alterations were appeared first of all as an increase in IgA level.
