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.

“When a woman drinks it’s as if an animal were drinking, or a child. Alcoholism is scandalous in a woman, and a female alcoholic is rare, a serious matter. It’s a slur on the divine in our nature.”
—Marguerite Duras (b. 1914)
“... your problem is your role models were models.”
—Jane Wagner (b. 1935)
“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)
“The only medicine for suffering, crime, and all the other woes of mankind, is wisdom.”
—Thomas Henry Huxley (1825–95)
