Abstract

Physical exercise exerts beneficial effects on the spatial learning and memory. High-intensity interval exercise (HIIE) has been proposed as a time-efficient physical exercise regimen. On the other hand, there were evidences that HIIE increased oxidative stress biomarkers and reduced antioxidant capacity, which resulted in oxidative damage. The present study aimed to investigate the effects of high-intensity interval exercise and moderate-intensity interval exercise on oxidative stress biomarkers and oxidative enzymes activity in the hippocampus and the spatial memory of ovariectomized rats. A total of 16 female Sprague Dawley rats aged 12 weeks were randomly assigned into 4 groups, i.e. the sham-operated (SO), ovariectomized without exercise (O), ovariectomized with high-intensity interval exercise (HIIE), and ovariectomized with moderate-intensity interval exercise (MIIE) groups. Rats of the exercise groups (HIIE & MIIE groups) performed 6 sessions of interval exercise per week for 6 weeks. The spatial memory of rats was measured using the Morris water maze procedure. The malondialdehyde (MDA) levels and activity of catalase (Cat) as well as glutathione peroxidase (GPx) in hippocampus were determined using spectrophotometry method. The spatial learning and memory retention of the moderate-intensity interval exercise group was significantly better than that of the high-intensity interval exercise group. The GPx activity of MIIE group was higher than any other groups. The SO group had the lowest hippocampal MDA level and highest Cat activity among groups. Moderate-intensity interval exercise reduces the ovariectomy induced-oxidative stress in the hippocampus and improves spatial learning and memory retention of ovariectomized rats.

Abstract

Background. Chronic stress caused by restraint stress induces an increase in corticosterone (glucocorticoid) that result decreased hippocampal vollume. Centella asiatica has long been used for various neurological disturbances in Southeast Asian countries. Aims. The research aims to investigate the effects of ethanol extracts of Centella Asiatica to prevent the decrease of hippocampal vollume after chronic stress. Methods. Thirty male adult rats (Sprague Dawley) with body weight of 250-350 gram was randomly subdivided into six groups of treatments: Nonstress control group was given 2% Pulvis Gummi Arabicum (PGA), Stress control groups( PGA 2 %), groups treated with fluoxetine 10mg/kgbw/day , and Ca150,  Ca300, Ca600 containing ethanol extracts of Centella asiatica with doses 150 mg/kgbw/day, 300 mg/kgbw/day, 600 mg/kgbw/day a, respectively followed by restraint stress.  After 21 days of stress, rats underwent Morris Water Maze test for 6 days, perfused, and hippocampus was collected for histological processing. Toluidine blue staining is used to asses the estimation of hippocampal volume. Results. The estimated hippocampal volume were 3.1512 ± 1.01 (nonstress), 2.4736 ± 0.10 (stress), 2.7018 ± 1.06 (Ca150), 2.7405 ± 1.19 (Ca300), 2.2678 ± 0.82  (Ca600) and 2.5818 ± 0.70 (Fluoxetine). Statistic test showed that there were no significant diferrence between stress control group and groups treated. Conclusion. There is no the significant effects of Ethanol extracts of Centella Asiatica to prevent the decrease of hippocampal vollume after chronic stress.
