Mental stress test-induced changes in pain sensitivity and haemodynamic variables

Changes in haemodynamic variables with thiopentone, methohexitone, propofol and etomidate.

Haemodynamic changes induced by prostacyclin in man.

Intra-arterial or intravenous infusion of prostacyclin at three dose levels (2, 5, and 10 ng/kg per min) in 10 subjects without evidence of coronary heart disease or cardiac failure, led to a distinct fall in peripheral and total pulmonary vascular resistances. This was accompanied by a drop in intra-arterial blood pressure, and the acceleration of heart rate. Stroke volume, cardiac output, mea...

Mood, performance, and pain sensitivity: changes induced by food constituents.

We examined the behavioral effects of the dietary constituents tryptophan and tyrosine on human mood, sensorimotor performance and pain sensitivity. Tryptophan and tyrosine are neurotransmitter precursors present in varying amount in protein-containing foods. Tryptophan (50 mg/kg) increased subjective drowsiness and fatigue but unlike many hypnotics did not impair sensorimotor performance. Tryp...

Immunologic and Cardiovascular Changes Induced by Mental Stress

Background Acute mental stress evokes responses in the cardiovascular and the immune systems. In particular, the subset of natural killer (NK) cells is found to be responsive to mental stress. The role of ,B-adrenergic mechanisms in these processes is the subject of this investigation. Methods and Results Healthy male volunteers (n=31) were subjected to two consecutive mental tasks. Subjects we...
