[Relations between the indicators of humoral immunity and psychological adaptation of pilots].

Peripheral blood serum A, M and G immunoglobulins were measured in 123 pilots, 22 to 42 years of age, distributed in groups as to the degree of frustrational tension (FT), related frustrational tension (RFT) and frustrational intolerance (FI). Inverse correlation was found between the indices of psychic adaptation (FT, RFT and FI) and the M immunoglobulin content. No evident correlation was traced between the levels of the circulating A and G immunoglobulins and the psychological peculiarities assessed in the pilots.
