New plaster provides rapid wound healing

What do you do when you accidentally cut with a knife? Most likely, you kleetsya place a band-aid on the wound, which protects the wound site from dirt and bacteria and also pulls the wound edges and accelerates its healing. Apart from the usual plasters, there are drugs, which are impregnated with nicotine and help to quit smoking, and capsicum plasters for pain. So why scientists do not impregnate the tapes substances that speed up the healing of tissues? American scientists from Harvard University have made it and now claim that this patch can treat even severe wounds.

New plaster provides rapid wound healing

to create a new type of plasters scientists inspired by the children in the mother's womb in embryonic form. It is known that wounds on their body to heal as soon as possible, and do not remain any traces on their site. The same is true of the skin of an adult, but wound healing is much slower. But why?

Skin Recovery

The fact is that when taking damage, fetal tissues begin to actively produce protein fibers that quickly constrict, thereby squeezing the skin around the wound. In 2003, scientists discovered that the most important role in this process is played by proteins TGF-Beta-3 involved in the development of the embryo and in the formation of tissues.

Human Embryo

In the same year, an experiment was conducted, during which a group of people with minor wounds inflicted gel without adding any medications, and another - a drug with the contents of the aforementioned protein. As expected, the wounds treated with a second agent, heal much faster.

The patch for wounds

The structure of a new type of adhesive protein TGF-Beta-3 is not included - it's probably due to the fact that high levels of this protein can trigger the development of Alzheimer's disease, because of which severely deteriorating memory in humans. However, despite the lack of protein, it is still faster tightens the skin and promotes healing. According to scientists, tape created by them consists of the gels, which are activated by the heat of the human body and are held firmly in the skin than conventional plasters. Also, it is composed of tiny particles of silver destroying microbes.

The effectiveness of patches has been proven by the example of mice and pigs - wounds on their bodies actually healed more rapidly than when using conventional adhesives. It was also noted that the new patch does not cause inflammation, which indicates its health safety. To officially recognize the effectiveness of the new dressing, it remains only to test them on humans, but that scientists need to get permission from the regulatory authorities.

Treatment of ulcers

Scientists believe that they have created band-aid, not only can treat minor cuts, but also serious injury. For example, it can be used to treat ulcers arising from diabetes mellitus, and pressure ulcers occurring in patients with prolonged bed rest.

All of this can be quite realistic, but still before the new material in hospitals, it is necessary to carefully check on people. At a minimum, scientists have yet to figure out how to behave a band-aid at low temperatures.
