It was done by the researchers of University of Tehran and University of Pisa in Italy: Making biodegradable wound dressings with fast absorption capability

According to the Public Relations report of the University of Tehran, quoted from the College  of Engineering, "Alireza Khardvar Kalor", a Master's student in polymer engineering at the University of Tehran under the supervision of Dr. "Mohsen Shahrosund", a member of the academic staff of the University of Tehran, and Professor "Dario Poppi" from the University of Pisa, Italy, it has developed biodegradable wound dressings with fast absorption capability, which is currently in the animal (laboratory) stage.

Dr. "Mohsen Shahrosund", the supervisor of this student research project, explaining that these hydrogel dressings are based on gelatin and sodium alginate, said: "These dressings have no cellular and systemic toxicity to the body due to the use of completely natural materials, and their structure It is similar to the structure of collagen fibers in skin tissue.

He continued: "These dressings accelerate the four-step process of wound healing, including hemostasis, inflammation, proliferation, and tissue regeneration, and after using these dressings, a clot forms at the bleeding site, which is an obstacle to prevent blood loss. and the entry of pathogenic agents into the body.

Dr. Shahrosund continued: "In the inflammatory phase, the wound is cleansed of foreign particles, and then the process of granulation or the formation of new tissue and blood vessels at the wound site begins with the deposition of extracellular matrices, including gelatin and sodium alzinate, which gradually and within 10 to 15 The day is replaced by the collagen tissue of the skin and finally, in the regeneration phase, the wound tissue is closed.

A member of the scientific faculty of Caspian College  of Engineering of University of Tehran stated that wound healing with these wound dressings is without skin scars, and stated: "The use of wound dressings prepared by this research group improves the performance of all four stages of wound healing and due to moisturizing the skin, it prevents It leads to skin scarring after wound treatment.

He further noted: "The important point in the preparation of these wound dressings is that the substrates prepared are without any harmful and allergenic chemicals, and therefore consumers can use this type of wound dressings without any complications."

The supervisor of this student research project added: "The viscoelastic properties of these wound dressings are very similar to the natural skin tissue, and this is the reason why the performance and mobility of the damaged tissue does not decrease in any way after using this type of wound dressings."

Dr. Shahrosund stated that the finished price of these Iran-made wound dressings in the Caspian Technical College is estimated at 30 thousand Tomans, and noted that the similar foreign sample of this type of product in dimensions equal to 5x5 square centimeters is sold in the market at a price equal to 200 thousand Tomans.

According to him, the wound dressings produced in the Caspian Engineering College are undergoing animal tests and, if they attract capital, they can be directly supplied to the market.

The skin is the largest organ of the human body and plays an important role in maintaining life and protecting the body against damage and microbial invasion. This integrated structure is actually a buffer between the body and the changes in the surrounding environment, and any disturbance in this integrity and function of the skin can be defined as a wound, which is caused by various causes such as trauma, surgery, diabetes, and burns.

Rapid treatment of wounds resulting from injuries, accidents, burns and surgery is one of the problems of hospitals and medical centers today. The use of wound dressing with high efficiency and effectiveness is required by all hospitals, medical centers and even ordinary people today.
