What do you do when you accidentally cut with a knife? Most likely, you glue adhesive tape to the wound site, which protects the affected area from dirt and bacteria, and also tightens the wound edges and accelerates its healing. In addition to the usual adhesive plasters, there are also medicinal plasters that are impregnated with nicotine and help to quit smoking, as well as pepper plasters to eliminate pain. So why do scientists not soak up these adhesive tapes with substances that accelerate tissue healing? American scientists from Harvard University have done this and now insist that even serious wounds can be treated with this plaster.
To create a new type of patches of scientistsinspired children in the womb in fetal form. It is known that the wounds on their body heal as soon as possible, and in their place there are no traces left at all. The skin of an adult also has the same property, but wound healing occurs much more slowly. But why?
The fact is that when receiving damage,embryonic tissues begin to actively produce protein fibers, which quickly narrow, thereby squeezing the skin around the wound. In 2003, scientists discovered that TGF-Beta-3 proteins play the largest role in this process, both involved in embryo development and tissue formation.
In the same year an experiment was conducted, duringwhich one group of people with small wounds inflicted gel without adding any medication, and the other - a medicine containing the above protein. As expected, the wounds treated with the second remedy healed much faster.
The composition of the new type of patch protein TGF-Beta-3 is notincluded - probably due to the fact that a high content of this protein can trigger the onset of Alzheimer's disease, due to which people have severely impaired memory. However, despite the lack of protein, it still quickly tightens the skin and accelerates healing. According to scientists, the adhesive tape created by them consists of gels that are activated by the heat of the human body and are held on to the skin more tightly than regular patches. It also contains tiny silver particles that destroy microbes.

The effectiveness of patches has been proven by the exampleMice and pigs - the wounds on their bodies did heal faster than with ordinary patches. It was also noted that the new patch does not cause inflammation, which indicates its safety for health. To officially recognize the effectiveness of the new dressing material, it remains only to test them in public, but for this, scientists need to obtain permission from regulatory authorities.
Scientists believe that they created the adhesive plastercan cure not only small cuts, but also serious wounds. For example, it can be used to treat ulcers that occur in diabetes mellitus and pressure sores that occur in patients with prolonged bed rest.

All this can be quite real, but stillbefore using the new material in hospitals, it must be carefully checked in humans. At a minimum, scientists have yet to figure out how a plaster behaves at low temperatures.
