| ergoloid mesylates | <chemical> Dihydroergotoxine monomethanesulfonate. A mixture of the mesylates of dihydroergocornine, dihydroergocristine, and the alpha- and beta-isomers of dihydroergocryptine. The substance produces a generalised peripheral vasodilation and a fall in arterial pressure and has been used to treat symptoms of mild to moderate impairment of mental function in the elderly. Pharmacological action: adrenergic alpha-antagonists, nootropic agents, vasodilator agents. Chemical name: Ergotoxine, dihydro-, monomethanesulfonate (salt) (12 Dec 1998) |

| ergometry | Any method of measuring the amount of work done by an organism, usually during exertion. Ergometry also includes measures of power. Some instruments used in these determinations include the hand crank and the bicycle ergometer. (12 Dec 1998) |
| ergon | <unit> A unit used to measure or represent the stability of a gene over the lifetime of a given organism. It is a function of the ratio of the adenine-thymine to the guanine-cytosine content of the gene, and is evidenced by the continual physical expression of the trait coded by the gene. (11 Nov 1997) |
