NEAVS Questions Boston Globe's Rat and Human Biology Article

February 9, 2001

Boston, MA 02107

Dear Editor,

Rats are biologically similar to humans??? The New England Anti-Vivisection Society (NEAVS) hopes readers will not swallow Marlene Cimons’ lopsided article Cheers, jeers on rat research (2-08-01). Cimons’ article states, "Typically, if a chemical causes cancer in rodents, it usually will cause cancer in humans too." The animal research industry wants us to believe that—and Cimons echoes their propaganda.

First, rat anatomy and physiology differ enormously from humans’. A few of the dissimilarities that could detrimentally affect research: rats rarely vomit; do not have a gall bladder; do not have sweat glands; cannot pant; are poor regulators of body temperature; have twice the concentrating ability for urine; and, have a heart rate four times a human’s.

Second, numerous rat studies of drugs were inaccurate when extrapolated to humans. A small sample: Flosint, an arthritis medication, proved fatal to humans yet was considered safe from testing on rats, dogs, and monkeys. Zelmid, an antidepressant, caused neurological damage in humans though tested on rats and dogs. Clioquinol, an antidiarrheal, caused blindness and paralysis in humans despite testing in rats, rabbits, cats and dogs.

One can find animal studies that show cigarette smoke, fiberglass, and saccharin are harmful – or harmless. This is true of almost any substance. Since animal research gives such varying results depending on species, sex, breed and a host of other factors, researchers’ results can be unintentionally or even intentionally misleading.

Then why do these antiquated, faulty animal tests continue? Because it is an enormous profit-driven industry.

Non-animal tests such as Corrositex, EpiDerm, EpiOcular, Irritection Assay System, are highly predictive for humans. Sadly, they do not get media attention. Rather, the animal industry’s stranglehold over the media continues to define science. Your readers deserve better, educated, and objective reporting.

Sincerely,

Theodora Capaldo, Ed.D.
