Bacterial Cellulose Membrane Experimentally Implanted in the Peritoneum of Wistar Rats-Inflammatory Immunoreactivity and Oxidative Stress.

Bacterial cellulose (BC) has been used for various applications; however, studies investigating the immunohistochemical characteristics of the inflammatory and scarring component in BC implanted in the peritoneum in vivo have not yet been fully described. This study aimed to evaluate the systemic and organic safety of BC through oxidative stress, blood, and serum biochemical markers, as well as the late inflammatory response in rats, using histopathology and immunohistochemistry. Forty-three rats (26 males; 17 females) received BC in the peritoneal cavity (implanted group-IG), while twenty-seven rats (12 males; 15 females) served as the control (sham group-SG).
