Four Unusual Animal Experiments

In the medical world of humans using animals as a tool in the development of an experimental drug discovery. Some of the animals that have a character similar to humans often once used as a sample for a drug test. Because the drug is often used in fact humans have ever tested on animals first.

One of the animals that often in the set as material tests by humans is a rat. Many of the animals that cause the problem in this House turns out to have in common is almost similar to humans. No wonder 95 percent of animal experiments in laboraturium is a rat. However, do you know if it turns out there are a lot of unusual animals out there that are used for animal experiments?

Despite the somewhat strange, and rare animals has some similarity with humans. So these animals used for experiments that are impossible in dangerous do directly in humans.

Fruit flies

Who would have thought fruit flies or Drosophila Melanogaster are animal experiments are important to humans? Yes, in the world of genetics, fruit flies have been a King of animal experiments for nearly 100 years.

Fruit flies used for research on the disease suffered by human beings. In addition to easy diternak, flies it can spawn hundreds of thousands in just one week. So scientists could easily observe if there are mutations.

Chromosomes of fruit fly is very large and easily mapped. And most importantly, about 75 percent of the human genes that are infected with the disease can be found in fruit flies. In addition, fruit flies, hox gene also has the same gene in humans that determines the growth of limbs while still in the womb.

Ferret

One of the shortcomings of the mouse when the animal will be made of the research was not sneezing, therefore it is impossible to put this animal as a Guinea pig for influenza or the flu. Fortunately, scientists have got a replacement mouse, namely the ferret. Ferret Mustela putorius furo, or is the furry mammals that are closely related to the otters and weasels.

Ferret could sneeze and suffered other respiratory diseases, such as flu. If the ferret could be sick like sick care of men, the ferret could be applied to humans. Therefore scientists have long been experimenting on vaccine and drugs for respiratory diseases in animals is funny.

Thanks to this, people can be one step ahead of flu virus infection problem, avoiding the large casualties due to the swine flu virus has now been evolved and lead to many dangerous diseases, such as swine flu.

Sea urchins

Believe it or not when it is still in the early growth stage, as in the womb, humans very similar to sea urchins or sea urchin (Echinoidea). The sameness will probably make you shocked, we and urchins alike grew out of the anus.

When humans first evolved in the womb, the first body part that appears is the anus then continues to grow in other parts of the body. This also happens on sea urchins, so scientists are studying the growth of early humans through animals. Making scientists don't have to bother and endanger research on pregnant women.

Moreover, embryonic sea urchins are more easily observed because it is outside the body. Different from human embryos stored safely in the birth.

Nematode worms

The worm Caenorhabditis elegans with the latin name is used as animal experiments not because of his similarity to humans, but due to the ' kesederhanaanya '. Yes, c. elegans has only a maximum of 959 cells in his body.

So it is very easy to research the development of every cell in the body of the worm. Not weird when c. elegans became the first order of gennya animals can be mapped by scientists.

Each cell of the worm is also very sensitive to RNA interference ' technique ' aka ' on/off ' genes. Using this technique, scientists can turn off and turn on the gene worm back repeatedly to uncover the function of each gene and its relation to disease.
