title: [Reversibility of the leukocyte activation state studied in a model of endogenous pyrogen formation by granulocytes].
abstract: The pyrogen-releasing capacity of rabbit exudate granulocytes can be temporarily suppressed during incubation in the whole plasma and then recovered during cell transfer into 0.15 M NaCl or stimulation with the bacterial lipopolysaccharide, pyrogenal. The inhibitors of protein synthesis added to the granulocytes when they are being transferred from plasma to 0.15 M NaCl do not suppress the pyrogen release. The inhibitory action of the whole plasma on the pyrogen release is due to the presence in it of potassium and calcium ions. The inhibitory factors of plasma reversibly suppress the pyrogen release but do not eliminate the leukocyte activation.
