title: Prolonged effect of psychological disturbance on macrophage chemiluminescence in the squirrel monkey.
abstract: The following study assessed changes in macrophage responsiveness after a 24-h period of psychological disturbance in mother and infant squirrel monkeys. Utilizing a luminol-dependent assay, an 80-min chemiluminescent burst was measured in blood monocytes in response to zymosan stimulation. Cells obtained from stressed mothers and infants showed significant increases in chemiluminescence (CL) as compared to baseline levels. Moreover, the elevated pattern of response persisted for at least 2 weeks after the mothers and infants were reunited. The initial change in CL was associated with increased pituitary-adrenal activity and leukocyte redistribution, but these measures returned to normal levels following reunion. Thus, this study has demonstrated a prolonged change in an immune parameter following a transient alteration in the psycho-endocrine status of the host.
