Activity of the first line antioxidant defense enzymes in the liver of pubertal rats during stress

摘要

Activities of catalase, glutathione peroxidase (GPx) and superoxide dismutase (SOD) have been investigated in the liver postmitochondrial fraction of pubertal rats exposed to stress. Short-term immobilization of pubertal rats caused a decrease of catalase and GPx activities. Long-term immobilization was accompanied by activation of GPx and SOD in the liver postmitochondrial fraction of late pubertal and adult animals, but not early pubertal rats.
