NIMALS HAVE BEEN USED as subjects in
biomedical research for decades. But moral
concerns over animal experimentation have led
to the formation of several hundred anti-
vivisectionist groups opposed to animal use,
many of them begun in the 1970s.
Most scientists at Michigan say they haven't been targets
of actions by research opponents in defense of animals. They
are concerned, however, that objections to their work may
some day interrupt it.
That work involves a tremendous number of specimens.
According to statistics provided by the office of the vice
president for research, University researchers used 98,710
animals between October 1, 1985 and September 30, 1986.
Over 70,000 of these were mice and rats, and another 11,000
were fish. Scientists also used more than 2,300 dogs, over
500 cats, 3,012 rabbits, 108 chickens, one goat, and 57
assorted reptiles, including at least one alligator.
Experimentation is conducted under guidelines, relatively
new proceedures at the University.
Dr. Bennett Cohen, a veterinarian with a background in
physiology, came to Michigan in 1962 to create a
University-wide program regarding research involving
animals. He was confronted by researchers who feared outside
interference with their projects. At that time, individual
scientists ran their own labs, hired their own staffs, bought
their own animals - and worked largely without regulations.
In the early 1960s, Cohen developed comprehensive rules
for the use of animals in the Medical School and
subsequently for the rest of the University, and then helped
write national guidelines. The result was the Unit for.
Laboratory Animal Medicine (ULAM), a department of the
Medical School responsible for administering the use of
animals throughout the University.
Those efforts also led to the creation to the University
Committee on the Use and Care of Animals (UCUCA).
Now all projects that involve animals in research must be
approved by UCUCA. Last year, the committe approved 725
proposals involving animal research. Dr. Daniel Ringler,

who succeeded Cohen as director of ULAM in 1985 and who
is an member of the committee, said only one-third to one-
half of the proposals approved are carried out, largely because
the National Institutes of Health (NIH) does not provide
funding for all approved projects.
Researchers must submit a 10-page form describing their
experiment, purpose, whether the experiment can be done by
artificial means, why the number of animals proposed is
necessary for the experiment, and what the fate of the animals
being used might be..
Most proposals are reviewed quickly, but projects using
"dogs, cats, or monkeys are looked at the hardest," said Alan
Price, associate vice president for research. Researchers who
submit applications that are vague and unclear are questioned
by UCUCA, he said.
The Humane Use category asks researchers to describe
what level of pain an animal might be subjected to. Category
A indicates little or no pain. Category B means animal will
experience some pain, and Category C experiments have the
potential for severe pain or permanant injury.
Dr. Jill Becker, an assistant research scientist in
psychology and UCUCA member, said the division between
B and C is fuZzy. She favors classifying experiments in
category C if a chance for pain exists. "I don't think anyone
wants to see animals suffer," she said.
About two-thirds of all research involving animals is done
in the Medical School, Ringler said. LSA research is done in
natural science departments like biology and chemistry.
Animals are also used in research projects in the School of
Dentistry and the School of Public Health, among others.
Animal research is done in 23 buildings on campusat a total
cost of about $35 million in 1984-85.
Most Medical School research is administered through
ULAM, a department which now has five full veterinarians
and seven more veterinary assistants. ULAM's offices offices
are hidden deep in the basement of the Medical Science I
Building. Many doors have special locks, but while security
is tight, Ringler says neither he nor the University have
anything to hide.
"We will give tours to any responsible person and take
them wherever they want to go," he said.

ways to combat them are tested in animals. Researchers also
study animals with internal systems similar to humans to get
a better understanding of the human nervous and
cardiovascular structures. Many animals are used to obtain
cells or to make anti-bodies, proteins in the blood that
combat diseases, to try and develop immunizations and cures.
Animals are obtained from a variety of places, but "the
vast majority are bred specifically for research" in the labs,
Ringler said. Prof. Charles Yocum, head of the biology
department, said researchers in his department "breed their
own rats to maintain a constant genetic pool. A slight
difference in genetic makeup can ruin an experiment."
Other animals are purchased from companies that
specialize in breeding animals for research. Some dogs and
cats used by researchers come from pounds and shelters.
Animal dealers, who must be federally licensed, buy them
from pounds after they've been held for a minimum of four
or five days. Shelters sell them for $2 to $4; dealers check
their health, condition them for research, and sell them to the
University for about $35 each.
Ringler said the number of animals the University uses
from pounds is miniscule compared to over 500,000 animals
killed in animal shelters statewide every year.
