title: The Anti-Inflammatory and Antioxidant Effects of Curcumin in Middle Ear Infection.
abstract: OBJECTIVE
  To investigate and analyze the anti-inflammatory and antioxidant efficacy of curcumin in experimentally induced middle ear infection.
  
  
  METHODS
  Twenty-four Wistar albino rats with otomicroscopic examination findings within normal limits were included in the study. Study groups were established after Streptococcus pneumoniae was inoculated into the middle ear cavity of all rats. No medication was administered to Group 1, the control group. Group 2 was administered 50 mg/kg/day amoxicillin intraperitoneally. Group 3 was administered 50 mg/kg/day amoxicillin together with 30 mg/kg/day curcumin intraperitoneally. Blood specimens and temporal bones were collected on the 10th day of medication from the 22 rats in which acute otitis media developed. Serum glutathione peroxidase and superoxide dismutase activities and malondialdehyde levels were measured. Inflammatory cell infiltration, vascular proliferation, and epithelial proliferation were assessed histopathologically in middle ear mucosa specimens, and the results were compared among the groups.
  
  
  RESULTS
  Malondialdehyde levels in the group given curcumin were significantly lower than those of the control group, while serum glutathione peroxidase activity was also lower compared to that of the control group. No significant difference was observed among the groups in terms of superoxide dismutase activity. Although there were no significant findings in terms of histopathological data, epithelial proliferation in the groups receiving antibiotherapy was suppressed compared to the control group. Similarly, curcumin was observed to have a positive effect on inflammatory cell infiltration. No significant changes were observed in terms of vascular proliferation.
  
  
  CONCLUSIONS
  With its wide and safe dose range, curcumin represents grounds for optimism in terms of anti-inflammatory treatment in acute otitis media.
