After about 10 days, doctors remove the bandage. The tilapia skin is applied directly onto the burned area and covered with a bandage, without the need for any cream. The fish skin has high levels of collagen type 1, stays moist longer than gauze, and does not need to be changed frequently. He says the tilapia skin treatment is more effective than bandages that need to be changed every two days. Patients, with limbs covered by fish skin, resemble creatures from a science fiction movie.Ĭar mechanic Antonio Janio badly burned his arm when a cylinder of soldering gas leaked. In medical trials, the alternative therapy has been used on at least 56 patients to treat second- and third-degree burns. Once cleaned and treated, it can last for up to two years, researchers say. University lab technicians treated the fish skin with various sterilising agents, and sent it to Sao Paulo for irradiation to kill viruses before packaging and refrigeration. The tilapia treatment can speed up healing by several days and reduces the need for pain medication, the Brazilian researchers say. "The fish skin is usually thrown away, so we are using this product to convert it into something of social benefit." "The use of tilapia skin on burns is unprecedented," said Odorico de Morais, a professor at Ceara University. In China, researchers have tested tilapia skin on rodents to study its healing properties, but scientists in Brazil say their trials are the first on humans. Scientists at the Federal University of Ceara in northern Brazil have found that tilapia skin has moisture, collagen and disease resistance at levels comparable to human skin, and can aid in healing. Tilapia is abundant in Brazil's rivers and fish farms, which are expanding rapidly as demand grows for the mildly flavored freshwater fish. Instead, gauze bandage, which needs regular changing - often painfully - is the norm. The researchers hope the treatment will prove commercially viable and encourage businesses to process tilapia skin for medical use.FORTALEZA, Brazil - Researchers in Brazil are experimenting with a new treatment for severe burns using the skin of tilapia fish, an unorthodox procedure they say can ease the pain of victims and cut medical costs.įrozen pig skin and even human tissue have long been placed on burns to keep them moist and allow the transfer of collagen, a protein that promotes healing.īrazil's public hospitals, however, lack human and pig skin supplies and the artificial alternatives easily available in Western countries. The tilapia skin, which has dried out and loosened from the burn, can be peeled away. Patients, with limbs covered by fish skin, resemble creatures from a science fiction movie.
