Draize-Test
This test has been especially designed for the testing of
medical, cosmetical and chemical substances, but also for the testing of the end
products, like creams, lipsticks, mascaras, face-lotion, soap, shampoos, powder,
hairspray, toothpaste, lacquer, detergent and everything, which could perhaps
touch one’s skin someday somehow.
The number of rabbits and other animals, which are killed by
this procedure day by day, must be some millions.
The rabbits, which are immobilised, sit in long lines of
cages for 72 hours. Their eyes are kept open by metal- or plastic clamps, so
that they’re not able to twinkle. In short intervals chemicals, poisons,
toxics and acids are dripped into their eyes. The animals cannot lick or scratch
themselves, and they do not have the possibillity of diluting these aching
substances either, because they have no tear gland. (That’s one important
reason for the use of rabbits for these kinds ot tests.)
The effects of these tests are evaluated by machines.
Depending on the tested substance the rabbits’ eyes get red, their cornea
(this is the outer skin of the eyeball) is injured, the tissues are destructed
or they build abscesses. The eyes are destroyed systematically in layers. If the
eyes are only red, the animals will be used again time after time till they
die.
Neither an anaesthetic nor a painkiller is given to the
animals.
In other tests the animals are sheared and the skin is cut
open. Then the substances are placed on these cuts till you can see open wounds
or swellings.
Cigarette tests
Cigarettes are also “tested“ by animals. Some
years ago 86 dogs (race: beagle) were forced to smoke 455 cigarettes every day.
This procedure took about one and a half year. After this time 12 of them got
pulmonary cancer. Although this test doesn’t say anything about the
physical reaction of human smokers, it’s still done with other
animals.
Medicament tests (for people who have kidney
trouble)
A special kind of tube is inserted into the sheeps’
neck-vein. Through this tube the sheep are connected with the dialysis machine.
Different doses of test-medicaments are mixed into the blood. Then some
blood-tests are performed. Athough a lot of sheep have repellent reactions like
falling blood-pressure, difficulty of breathing, unrest, staggers and, of
course, a lot of pain, the experiments are repeated seven times with changed
conditions.
The sheep which didn’t die during the tests are killed
after the last one, because now they are useless for further
research.
The effect of a closed artery
In this experiment the necks of the mice are cut open in the
middle, so that the blood-vessels of the neck lie open and now some are
contracted with loops.
A clamp is fixed temporarily at the inner artery of the neck
so that the blood stream is stopped. After a cut into the other artery a tube is
pushed forward to the brain, towards shut the middle cerebral artery. Some mice
are infused a colouring substance into their hearts. A couple of minutes later
they are decapitated. The brains are cut out and then examined.
In the case of some other mice the artery occlusion takes
three hours. There some other special products are examined and a radio-active
substance is infused into the belly.
The experiments are finished by the freezing of the mice.
Then the brains are cut out and are examined.
