Abstract
We investigated the smooth muscle contraction in response to noradrenaline (NA), endothelin-1
(ET) and 5-hydroxytryptamine (5-HT) in the omental artery and vein segments from a
67-year-old woman with idiopathic orthostatic hypotension. The blood vessels were
obtained during the abdominal surgery and investigated in vitro. Noradrenaline, endothelin-1
and 5-hydroxytryptamine all induced a contraction in the artery and vein segments.
Compared to the literature, the sensitivity to noradrenaline was 10 times higher than
expected in the vein. In the artery, the sensitivity to noradrenaline and in both
the artery and vein, the sensitivity to endothelin-1 and 5-hydroxytryptamine was similar
to that reported in the literature. These results suggest that the patient had developed
an isolated hypersensitivity to noradrenaline in the veins, probably due to an impairment
of the sympathetic activity.
