PURPOSE The aim of this experimental study was to evaluate through a clinical and histopathological analysis the tissue reactivity caused by two monofilament sutures nylon and poliglecaprone 25 on the internal and external sutures in rats. METHODS For this study, we used forty male Rattus novergicus (Wistar rats). The experimental procedures were incisions and divulsions performed on the back...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...
