WHY sharks rarely get sick?
Powerful, swift, and deadly rulers of the seas – sharks – can cause conflicting emotions, people.
Primal fear, and sometimes disgust in an incredible way combined with admiration and a desire to learn, understand and… to get acquainted with the graceful and unpredictable of predators.
How ironic that a death threat stirs our interest and stirs the imagination, forcing to closely monitor the movements of sharks, at each moment trying to predict her behavior. Apparently, this “unhealthy” interest was inherited from distant ancestors, whose lives depended on careful observation of a dangerous predator, from studying his habits and habits.
But not only ancient instincts prompt the person to study this wonderful work of nature. The shark is a unique example of sustainability.
In addition, the history of sharks goes back many millions of years, the modern representatives of this species are striking in their invulnerability regarding various diseases, insensitivity to pain and ability to survive even after serious injury.
Modern scientists suggest that the viability of sharks – the result of an effective immune system. Most sharks live to extreme old age: 70, and 100 years. Their body is extremely resistant to various infections and the development of tumors. For example: of the 25,000 studied sharks the cancer is found in only one. And their ability to quickly heal even the most terrible wounds are legendary.
People are primarily interested in the resistance to cancer. Primitive but very effective the immune system of sharks produces antibodies that can recognize and destroy cancer cells. It is very important that these antibodies are able to survive and operate even in high temperatures, acidic or alkaline environment. This gives hope that they will be able to adapt and in the human intestine.
Already conducted successful experiments on the treatment of cancer through the introduction of shark antibodies. Similarly, the doctors plan to deal with a number of other diseases, including malaria and arthritis.
