BACKGROUND
The inflammatory cells documented in chronic otitis media with effusion (OME) spontaneously release oxidants which can induce middle ear (ME) epithelial cell damage. Glutathione (GSH), a major extracellular antioxidant in humans, plays a central role in antioxidant defense.
OBJECTIVE
To
Melatonin plays a role in the prevention of oxidative damage. In the present study, we investigated whether the increased oxidative stress in experimental otitis media with effusion (OME) induced by histamine is reflected in erythrocytes and middle ear effusion fluid. Lipid peroxidation in effusion
The aims of our study were to assess whether the increased oxidative stress in experimental otitis media with effusion (OME) induced by histamine was reflected erythrocytes and middle ear effusion fluid by lipid peroxidation; to survey the alterations in antioxidant enzyme activities in experimental
Context • Oxidative stress and tissue-damaging, oxygen (O2)-related, free-radical formation is inherent in human metabolism, and the tissues of the ear, nose, and throat (ENT) have an increased exposure to injury from those substances. Because glutathione (GSH) is a major component in an antioxidant
CONCLUSIONS
The high oxidant levels in chronic otitis media with effusion (OME) observed in our research and the improvement seen in children with chronic OME after antioxidant treatment suggest that oxygen-derived free radicals play an important role in chronic OME.
OBJECTIVE
OME is a common
Increasing evidence implicates free radicals in the pathogenesis of inflammatory disease, including otitis media. The anti-oxidant enzymes catalase, glutathione peroxidase and superoxide dismutase protect tissues from the destructive effects of free radicals. Our previous work has shown depressed
The aim of this prospective experimental animal study was to determine whether selenium had a protective effect on oxidative stress in rats with acute otitis media, by measuring the alterations of antioxidant parameters and lipid peroxidation on days 4 and 10 after inoculation into the middle ear.
OBJECTIVE
Antioxidant enzymes status was investigated in children with acute otitis media (AOM) and acute tonsillitis. The aim was to determine the effect of oxidative damage due to free radicals on the antioxidant enzymes status in children with AOM and acute tonsillitis.
METHODS
We measured
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
Reduced glutathione (GSH), a potential factor in the chronicity of human otitis media, was tested to determine its potency in the recurrence of antigen-induced otitis media in chinchillas sensitized with human serum albumin (HSA). GSH instillation into the healing middle ear bulla reproduced a level
OBJECTIVE
To underline the effect of oxidative stress in chronic otitis media with and without cholesteatoma and to compare the oxidative stress values in the serum and tissue specimens in these two forms.
METHODS
The study included a total of 75 individuals, 35 cases with chronic otitis media (COM;
OBJECTIVE
Vitamin A plays a role in the prevention of oxidative tissue damage. In the present study we investigated therapeutic role of this substance on healing of middle ear mucosa in experimental acute otitis media (AOM).
METHODS
Otitis media was induced by inoculating Streptococcus pneumoniae
OBJECTIVE
Determine the possible role of oxidants and antioxidants in the pathogenesis of otitis media with effusion in children.
METHODS
Randomized controlled trial, tertiary referral center. The study group was made up of children with otitis media with effusion who were to undergo bilateral
OBJECTIVE
Recurrent episodes of acute otitis media (AOM) and acute tonsillitis (AT) are a common problem in infectious disorders during childhood and are major cause of morbidity in children. The organism maintains defense systems including nonenzymatic antioxidants such as Vitamins A, E and C and
OBJECTIVE
The purpose of this study was to determine if free oxygen radicals (FORs) and antioxidant enzyme activities have some role in pathogenesis of otitis media with effusion (OME) in children with adenoid hyperplasia.
METHODS
Seventy-four patients were enrolled in three groups of this study.
