Early fragmentation of polyester urethane sheet neither causes persistent oxidative stress nor alters the outcome of normal tissue healing in rat skin

Sandro M. Sgrott, Rodrigo dʼEça Neves, Armando José d'Acâmpora, GERALDO J.S. BERNARDES et autres

Silicone breast implant is associated with complications inherent to the surgical procedure. Prosthesis coating with polyurethane, however, commonly reduces the incidence of such complications. In this paper, the authors evaluated the inflammatory histomorphometric profile and oxidative damage associated to the implant of …

Effects of perioperative hypothermia and reactive oxygen species in the healing of colonic anastomosis in rats

João Carlos Costa de Oliveira, Camila Helena de Oliveira, Henrique Eduardo Oliveira, Aline Pereira et autres

PURPOSE: We evaluated the hypothesis that induced perioperative hypothermia (32 ± 1ºC) affects the redox balance in the tissue of colonic anastomosis in rats by modifying biochemical enzymatic and non-enzymatic markers related to oxidative stress. METHODS: Forty-eight male Wistar rats were randomly …
