Indian researchers have developed an ointment derived from wood that can speed up healing of burn injuries, check infection and preclude the need for repeated dressings.The starting point of the unique water-based gel is lignin, the major component of wood (15-30 per cent) and one of the most abundant renewable feedstock.<\/p>\n
\u201cThis hydrogel has multiple uses. It is a dressing material, an anti-infective ointment, a drug carrier and also has anti-inflammatory properties,\u201d scientist Ranadhir Chakraborty, of OMICS Laboratory, Department of Biotechnology, University of North Bengal (NBU), told IANS about the innovation documented in Nature Scientific Reports in April this year.<\/p>\n
Explaining the motivation for the work, Chakraborty highlighted the clever mechanism adopted by bacteria in infecting the burn wounds and avoiding the destructive effects of anti-biotics.<\/p>\n
\u201cWhat happens in burn wounds… when patients suffer from third-degree burning, they suffer from severe infection. The infection occurs not because of the burning but because the burn patient has to be dressed regularly and the wound dressing invites some nasty pathogens from air and that makes the whole thing untreatable,\u201d he said.<\/p>\n
\u201cBasically, these pathogens are bystanders, always present in environment, but in these cases they start growing on the wound,\u201d he added.<\/p>\n
Moreover, because these communities of bacteria grow inside their own protective bubble (called a biofilm), this shields them from action of anti-biotics.<\/p>\n
\u201cSo, we thought if we could design certain dressing materials which can stay on for a longer period of time and release the drug slowly to the wound, then that will be pertinent management for burn treatment. Repeated dressings and application of fresh ointment over the burnt region is not required with our innovated ointment,\u201d he said about the ointment tested on laboratory rats with skin burns.<\/p>\n
The work has been done in collaboration with scientists at the Indian Institute of Technology, Kharagpur, Jawaharlal Nehru University, New Delhi, NBU and Rush University Medical Center, Chicago.<\/p>\n
The paper states that the biocompatible hydrogel was developed from \u201crenewable lignin after surface modification with a hydrophilic polyoxazoline chain by chemical grafting approach which showed versatile benefits to speed up the wound healing process\u201d.<\/p>\n
