No frequent dressing changes were needed. Resultsįish skin-dressed wounds showed a significant ( P < 0.0001) reduction in microbial counts (Total viable bacterial count, Staphylococcal count, and Coliform count), a significant ( P < 0.0001) decrease in the wound size, and a significant reduction ( P < 0.0001) in the epithelial gap compared to the untreated wounds. Wounds were evaluated microbiologically, grossly, and histologically on days 7, 14, and 21 post-wound inductions. Wounds on the right metacarpals (treated wounds, n = 9) were dressed with sterile fish skins, while wounds on the left metacarpals (control wounds, n = 9) were dressed with sterile non-adherent dressing pads without any topical applications. Bilateral, circular full-thickness excisional skin wounds (2 cm in diameter) were created on the dorsal aspect of the mid-metacarpals of each donkey. Here, fish skin dressings were obtained from fresh Nile tilapia (Oreochromis niloticus and sterilized by immersion in silver nanoparticles (AgNPs) solution for 5 min, with no change in collagen content. The study was conducted on nine clinically healthy donkeys ( n = 9). ![]() The aim of the present study was to evaluate the Nile tilapia skin as a biological dressing for full-thickness cutaneous metacarpal wounds in donkeys. Jeanne Lee, the interim burn director with the University of California at San Diego, told Stat News.The use of biological dressings has recently emerged in the management of burns and wounds. “I’m willing to use anything that might actually help a patient," Dr. Eventually, though, the practice could spread to other countries, including the US. Once the packaged skin is treated to sterilize it and kill off any viruses, it can be refrigerated and will keep for up for two years.įor now, the method is still in clinical trials, with 56 people receiving treatment with the skins already. That's in part because it's considered fish-farm waste. The tilapia skin is also relatively inexpensive, costing 75 cents less than traditional bandages per application. In my case, I did not need it, thank God." Car mechanic Antonio Janio used the treatment after getting a burn on his arm. Tilapia skin also appears to relieve some of the pain. Here, doctors wrap a child's burnt skin with tilapia skin. But in more extreme cases, the tilapia needs to be changed out, though not as frequently as the gauze-and-cream combination does. ![]() In some cases, the sterilized tilapia skin can be left on until the patient's skin starts to scar. Tilapia is a common fish found in Brazil's rivers and fish farms, which makes the skin readily accessible for the experimental treatment. Edmar Maciel, a burn specialist at the institute told Stat News. “We got a great surprise when we saw that the amount of collagen proteins, types 1 and 3, which are very important for scarring, exist in large quantities in tilapia skin, even more than in human skin and other skins,” Dr. ![]() When they analyzed the tilapia's skin, they found something unexpected. So the team looked for other options, including sterilized tilapia skin. But at the José Frota Institute, doctors were only able to use burn creams and gauze that had to be changed out frequently, a painful process. Using tissue can often help speed up the healing process. Second- and third-degree burns are painful, and occasionally deadly depending on how widespread they are on the body. Here's the story of how the team discovered this unconventional new approach. That shortage led researchers at the José Frota Institute to turn to tilapia as an alternative treatment for people in the community who suffered from burns. In Fortaleza, Brazil, however, those tissues weren't readily available. Traditionally, burns are treated using pig and human tissue, which transfer collagen, a healing protein, to the victims' skin. Here's how the team came to the unconventional approach.īrazillian doctors are taking an experimental approach to treating burns: using tilapia skin. A city in Brazil is using tilapia skin as an experimental approach to burn treatment.
