Haematological changes during acute mental stress.

摘要: Summary To study haematological effects of emotional stress, blood samples were obtained from 29 healthy, normotensive, non-smoking males aged 20–34 years before, during and after 10 min mental arithmetic. There significant increases in pheripheral cell count, haemoglobin concentration, haematocrit response to stress. Parallel these changes heart rate, systolic diastolic pressure observed. The relative increments leucocyte (8%) platelet (3·5%) count significantly higher than the increase concentration (2%). was a positive correlation between mobilization leucocytes, whereas erythrocyte showed correlations with rate reactivity. It is concluded that stress causes an could not solely be accounted for by concurrent haemoconcentration.
