Intratracheal co-administration of antioxidants and ceftriaxone reduces pulmonary injury and mortality rate in an experimental model of sepsis.

Background And Objective: Recent studies showed that both sepsis and antibiotic therapy are associated with cell death and linked to reactive oxygen species generation. This study investigated the effects of intratracheal administration of combinations of antioxidants (n-acetyl cysteine (NAC), vitamins C and E) in the treatment of sepsis-induced lung injury.

Methods: Ninety-six male Wistar rats subjected to sepsis were treated with ceftriaxone plus NAC with or without vitamins C and E and compared to appropriate controls.

Analysis of fungal contamination and disinfection of toothbrushes.

The aim of this study is to determine the fungal species in the toothbrushes of residents of a neighborhood on the east side of Teresina - PI, and to assess the efficiency of a disinfection method based on 2% sodium hypochlorite. Fifty toothbrushes were divided into two groups: group A comprised 30 toothbrushes used by the residents and group B (control group) 20 new toothbrushes. Fungal evaluation was conducted in Sabouraud culture medium containing chloramphenicol and CHROMagar Candida.
