Purpose: To observe the histological alterations in the liver and biochemistry in the blood that can happen in Wistar rat, after the ligature of right hepatic duct.
Methods: In this study were used rats (n=46) of Wistar pedigree. The animal groups (n=46) were distributed in 6 experimented sub-groups (n=6).
Purpose: To investigate the influence of castration in early periods of development on survival to experimental acute sepsis.
Methods: Four groups of 10 (ten) Wistar rats were used. The groups were comprised of males (M), females (F), males castrated on the fourth day of life (CM) and males castrated on the fourth day of life with testosterone replacement (CMR).
Purpose: To compare the use of polypropylene and PTFE meshes in the treatment of incisional hernias made experimentally on Wistar rats.
Methods: The experiment used 24 Wistar rats divided into three cohorts: C-A (ressection of a segment of abdominal wall), E-A (ressection and placement of PTFEe mesh), E-B (resection and placement of polypropylene mesh). After 28 days, the mesh and the surrounding tissue were removed and submitted to macroscopic analysis (assessment of the abdominal wall for presence of abscess in the surgical wound and/or skin necrosis, and adhesions) as well as microscopic analysis (presence of fibrosis, necrosis and abscess, counting of macrophages, mononuclears and polymorphonuclears).
Purpose: To evaluate the inflammatory response of potentially infected wounds treated with isotonic saline solution, chlorhexidine and PVP-I, seven days after surgery.
Methods: Thirty-two male rats were used, divided into 4 groups. All animals had their surgical wounds infected with a standard bacterial inoculum.
