It can also be injected under the skin, into a vein, or into the lining of the abdomen; mixed into the animals' food; inhaled through a gas mask; or introduced into the eyes. Experimenters observe the animals' reaction, which can include convulsions, labored breathing, diarrhea, constipation, emaciation, skin eruptions, and bleeding from the eyes, nose or mouth. Often to get the data they need, scientists have to repeat one test on many different animals. After the repeated torture, most animals are killed (if not already dead due to the experiment), to better examine what effect the drugs had on their bodies (Put Your"). .
The LD-50 test, which stands for Lethal Dose-50%, means that out of all the animals tested on, 50% of them died. To perform the test, scientists force tubes down animals' throats and noses to pump drugs into them. Even though the LD-50 test has been banned in parts of Europe and the United States, scientists still use this test to determine toxicity of drugs ("Animals "). Another regularly used test is the Draize test of which there are two common types: skin and eye irritants. Guinea pigs are the most commonly tested on animal for the Draize test. Their skin is cleaved and chemicals are rubbed on their exposed and bleeding flesh. They are then bandaged up and left with the burning chemicals on them for many days. For the eye irritant version of the test, rabbits' eyes are clamped open and have chemicals squirted into them. The suffering rabbits are then left in stocks to keep them from moving or blinking the chemicals out ("Animals "). Not only do private companies perform these inhumane and horrific practices for the 'benefit' of humans, the government is highly involved too. .
The government is behind most animal experimentation's, and requires all chemical companies to test on animals to simulate a human's reaction. The government does their own testing, and in just one experiment, could kill 2,000 animals.
