The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database.

Term:
vasoconstrictor-induced blood vessel contractile force expressed as percent of force at baseline
A calculated measurement in which the difference between the contractile force of a blood vessel in response to a vasoconstrictor and the baseline contractile force exerted by that vessel in the absence of any external stimuli, is divided by the baseline contractile force measurement and the result expressed as a percentage. A vasoconstrictor is any agent or condition that narrows blood vessels by constricting the smooth muscle in the vessel walls.
