Abstract
Context: Ovarian hormone deficiency observed in menopausal women increases the production of reactive oxygen species, which could be implicated in central sensitization subjacent in chronic functional pain syndromes. Aims: To examine the hyperalgesic state induced by ovariectomy in adult rats and its relation to some oxidative stress outcomes. Methods: The female Wistar rats were divided into normal, sham ovariectomized (OVX) and OVX groups, which were tested for mechanical and thermal hypernociception during 6 weeks and a single acetic acid-induced test 6 weeks after surgery. Redox biomarkers determinations of superoxide dismutase (SOD) enzyme activity, glutath...
