Animal Models in Chemistry and Medicine
Animal models are used to learn more about a disease, its diagnosis and its treatment, with animal models predicting human toxicity in up to 71% of cases. The human equivalent dose (HED) or human equivalent concentration (HEC) is the quantity of a chemical that, when administered to humans, produces an effect equal to that produced in test animals by a smaller dose. Calculating the HED is a step in carrying out a clinical trial of a pharmaceutical drug.

Famous quotes containing the words animal, models, chemistry and/or medicine:
“All the lies and evasions by which man has nourished himself—civilization, in a word—are the fruits of the creative artist. It is the creative nature of man which has refused to let him lapse back into that unconscious unity with life which charactizes the animal world from which he made his escape.”
—Henry Miller (1891–1980)
“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
—Marshall McLuhan (1911–1980)
“Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes. It made a believer of me more than before. I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,—not an empty chamber, in which chemistry was left to work alone, but an inhabited house,—and for a few moments I enjoyed fellowship with them.”
—Henry David Thoreau (1817–1862)
“After you eat always take a walk, and you’ll never have to go to a medicine shop.”
—Chinese proverb.
