Incredible application of the web for medical purposes Bashny.Net

This group of arthropods is called up mixed feelings. Most people doesn't like spiders, unfriendly and looks like a spider web, if she had the misfortune to meet on the way. Meanwhile, the use of the web for medical purposes, and not only allows you to include it in the category of interesting, unusual, environmentally friendly and healthy natural materials.

 




The piece of amber, scientists have discovered the oldest spider's web, preserved to our times. Her age is about 140 million years. Earlier I found the amber, which well preserved the ancient spider, his age of 120 million years. Thus, spiders are quite ancient creatures than previously assumed scientists.

 

What is web



The web is a protein that is secreted from the numerous spinning tubes spider and enriched in alanine, glycine and serine. In the process of forming a web of fabric, is a structural change of a protein, it hardens on the outside but still liquid inside.

 

The combination of two types of proteins: durable spidroin-1 and elastic spidroin-2, form the basis of a frame thread. This combination explains the unique properties of the web.

 

Using the web for medical purposes



Among the recipes of traditional medicine are the following: to stop the bleeding from the abrasion or wound, you need to put purified from insects and debris the web. She not only has hemostatic effect, but also promotes rapid healing of tissues.

 

Valuable properties of the web could not go unnoticed by modern medicine, and now research in the field of its practical application. In the newest material interested surgeons and transplantation, for use as a tool for sutures, artificial ligaments and tendons.

 

Possessing antibacterial properties, spider fiber in the form of films, could serve as a healing covering for burns and wounds, which accelerate the regeneration of the skin and not rejected by the body.

 

Not yet able to synthesize these kind of proteins by chemical means, but some of the successes scientists can boast. For example, the artificial analogue of spider thread, which is only 4 times less durable than natural. It can already be considered an achievement because the gap it higher than tendon or bone.

 

Hanover scientists also conduct research in this direction and declare that soon there will be new methods of plastic surgery, based on stitching people have damaged nerves. They note that the web possesses all the necessary qualities: elasticity at break, camerastore in the body and improved "survival" without inflammation.

 

In turn, the creation of artificial skin based on web for those people who needed a transplant.

 

Success has crowned the experiments and a team of researchers from tufts University (USA). In the course of the experiments was obtained the modified proteins of the web, which are joined to diseased cells, ignoring healthy. This was a kind of platform for transporting therapeutic genes into the cells of the body.

 

Extensive use of web for medical purposes requires a huge amount of spiders, therefore, scientists are in search of such a synthetic silk, which would have the properties of natural spider silk, but it was available for practical use.
