The.most.important.aims.of.the.treatment.of.burns.are.pain.alleviation,.prevention.of.wound.desiccation.and.body.fluids.loss,.prevention.of.microbial.
infection,.and.minimizing.or.preventing.excessive.scarring.
Nanostructured.microbial.cellulose.is.particularly.well.suited.for.the.treatment.of.burns,.irrespective.of.their.degree.and.wound.surface.area.(Bielecki.
et. al.. 2002).. It. not. only. substantially. reduces. pain. by. heat. absorption. and.
maintains.moisture.around.the.injury,.but.also.stimulates.the.processes.of.
necrotic.tissue.removal.and.granulation.tissue.development..Clinical.trials.
have. revealed. that. BNC. dressings. considerably. shorten. scab. demarcation.
and.burn.healing.processes,.give.excellent.cosmetic.outcomes,.and.are.very.
well.accepted.by.patients.
Hernia
Hernia. is. defined. as. the. protrusion. of. an. organ. or. the. fascia. of. an. organ.
through.the.wall.of.the.cavity.that.normally.contains.it..Most.commonly.it.
develops.in.the.abdomen..Postherniation.abdominal.wall.repair.was.found.
to.have.better.outcomes.when.mesh.scaffolds.were.used.(Melman.et.al..2011)..
These.scaffolds.are.synthetic.(polypropylene,.polyester,.or.expanded.PTFE),.
composite. (synthetic. meshes. covered. by. a. protective. membrane. against.
adhesion.to.bowels),.or.biological.(grafts.harvested.from.human.or.animal.
dermis,. pericardium,. or. intestinal. submucosa).. Studies. on. animal. models.
