New patch ensures quick healing of wounds
Source:
What do you do when accidentally cut with a knife? Most likely, you will pull on the wound a band-aid that protects it from dirt and bacteria and also tightens the wound speeds up its healing. In addition to the usual patches that are impregnated with nicotine and help to quit Smoking, and capsicum plasters pain relief. So why would scientists not to impregnate these tapes are substances which accelerate the healing of tissues? American scientists from Harvard University made this and now claim that this patch can heal even serious wounds.
Creating a new type of plasters scientists was inspired by the children in the womb in embryonic form. It is known that wounds heal on their body in the shortest possible time, and in their place do not remain any traces. The same is true of the skin of an adult, but the healing is much slower. But why?
restoration of the skin
The fact that damage, embryonic tissues begin to actively produce protein fibers, which rapidly constrict, thereby squeezing the skin around the wound. In 2003, scientists have discovered that the most important role in this process is played by proteins of the TGF-Beta-3 involved in embryonic development and tissue formation.
human Embryo
In the same year an experiment was conducted in which one group of people with small wounds, apply the gel without adding any medicine and the other medicine with the content of the aforementioned protein. As expected, the wounds treated a second tool heal much faster.
Patches for wounds
The structure of a new type of adhesive protein TGF-Beta-3 is not included — this is probably due to the fact that high levels of this protein could trigger the development of Alzheimer's disease, because of which people have much worse memory. However, despite the absence of protein, it is still faster tightens the skin and accelerates healing. According to scientists, they created the adhesive tape consists of gels, which are activated under the influence of heat of the human body, and is held to the body is stronger than conventional plasters. Also it is composed of tiny silver particles that destroy microbes.
Schematic representation of wound closure
The effectiveness of the patches was demonstrated on the example of mice, and pigs — wounds on their bodies do heal faster than when using conventional plasters. It was also noted that the new patch does not cause inflammation, which means it is safe for health. To officially recognize the effectiveness of a new dressing material, we only test them on humans, but scientists need to obtain permission from the regulatory authorities.
ulcer Treatment
Scientists believe that they created the band-aid can treat not only small cuts, but serious wounds. For example, it can be used for the treatment of ulcers that occur in diabetes and pressure sores occurring in patients with prolonged bed rest regime.

All of this can be real, but still before using the new material in hospitals, you need to carefully check on the people. At least, scientists have yet to figure out how the plaster at low temperatures.
