endothelin
- noun

:
endotelina
- Doctors often measure endothelin levels to assess the risk of hypertension in their patients.
- plasma endothelin
- endothelin concentration
- endothelin release
Examples
-
Whether the lack of increase in plasma endothelin in patients with autonomic failure contributes to their orthostatic hypotension remains to be defined.
Academic text (1991) -
Needless to say, the possibility that patients with autonomic failure clear plasma endothelin more rapidly than do normal individuals cannot be excluded from our data.
Academic text (1991) -
In normal subjects, upright tilt did not change arterial pressure and significantly increased the plasma concentrations of endothelin and vasopressin.
Academic text (1991) -
In subjects with vasovagal syncope, arterial pressure dropped and the plasma concentrations of endothelin and vasopressin rose.
Academic text (1991) -
In patients with autonomic failure, upright tilt induced a considerable fall in arterial pressure, no rise in plasma endothelin, and a slight increase in plasma vasopressin.
Academic text (1991) -
Plasma concentration of endothelin was determined by radioimmunoassay employing anti-endothelin-1 antiserum, 125I-endothelin-1, and endothelin-1 standards (Peninsula Labs, Belmont, California, USA).
Academic text (1991) -
The finding (n3) that in normal subjects plasma concentration of endothelin increased with upright posture and decreased during volume expansion raises the possibility that endothelin is a circulating hormone involved in arterial pressure control.
Academic text (1991) -
Increased levels of endothelin can lead to higher blood pressure in patients with cardiovascular conditions.
-
Research shows that endothelin plays a significant role in the regulation of vascular tone.

Morphology
endothelin = endothelium (semi-transparent) = endothelium + in
Formally built from 'endothelium' + '-in' (a protein-naming suffix); this is predictable to readers familiar with biomedical naming but not to average B1 learners.
Etymology
The word endothelin comes from endo- meaning 'inside' and endothelium, the 'lining' of blood vessels, with the protein ending -in. So endothelin is a protein made by the vessel's inner lining that makes vessels narrow and can raise blood pressure.
