|January 1, 1981
Abstract:
The postflight investigation of cell mediated immunity of seven cosmonauts showed significant increase in spontaneous activity of lymphocytes of peripheral blood and decrease in stimulation of lymphocytes cultured with PHA at R + O. Variations in these parameters were transient, remaining within physiological limits. Two cosmonauts displayed a stable increase in lymphocyte activity during blast transformation test with Staphylococcus aureus culture filtrate.
