Effects of life events and stress on neutrophil functions in elderly men

We investigated the relationships between neutrophil function measured using the nitroblue tetrazolium (NBT) reduction test and measurements of psychological stress and life events among 81 men aged over 60？years.The numbers and scores for life events were significantly higher (p？<？0.01, respectively) in a group with values reflecting phagocytosis below the median than in a control group.Chronic psychological stress due to life events decreases neutrophil functions among elderly men.
