Frogs were made into a collagen bandage for the treatment of trophic ulcers

Scientists from the Nanyan University of Technology of Singapore have developed technology for the production of collagen from frog skins; in the first stage, pollution is removed from the skin, the material is mixed into pasta from which pure collagen is extracted, and is used by developers to produce biodegradable and biocompatible bandages.

Researchers say that when applied to a complex trophic wound, such a "plastic" accelerates healing by creating a porosous layer to coagulate leukocytes and healing agents, and it also serves as a protective barrier that prevents bacteria from entering, while maintaining the humidity of the wounds.

The authors note that the collagen in the new Band-Aid functions as a construction forest: the cells create a support structure and allow the migration of neighbouring cells; as the skin cells reproduce, the Band-Aid is completely dissolved and replaced by new skin.

Although frog meat is considered to be delicacy and rare in many parts of the world, it is a popular product in Singapore, and the skins of frogs grown on the farm are usually simply discarded, which means that the manufacture of bandages will not cost much of the components.

Trophic ulcers are long-term tissue defects that are difficult to heal, most of which develop against the background of varicose vein expansion, which leads to chronic venous failure; these wounds heal for a very long time and it is important to protect against infectious infection.

Scientists believe that as the population ages and diabetes spreads, the need to treat complex trophic ulcers will only increase; a new patch is a possible solution.
