Effect of exercise training on liver antioxidant status of deoxycorticosterone acetate salt induced hypertensive rats
Bibliographic record
Abstract
Several animal models have been developed to study the pathogenesis of hypertension. Deoxycorticosterone acetate (DOCA) salt induced hypertensive rats are adrenal models used to mimic human Conn's syndrome. Because previous studies showed a beneficial effect of chronic exercise (swimming) on the development of arterial hypertension in spontaneously hypertensive rats (which appears similar to human essential hypertension), we decided to evaluate the effects of swimming on DOCA-salt induced hypertension and liver antioxidant status. Therefore, the aim of this experiment was to study whether the swim training would improve hypertension and liver antioxidant status in DOCA-salt rats. DOCA-salt rats and control Sprague-Dawley rats were trained to swim 1 h/day, 5 days/week for 6 weeks and were sacrificed 48 h after the last exercise period. Systolic blood pressure was recorded before the sacrifice, and liver antioxidant status was evaluated in hepatic homogenates after the sacrifice. Swim exercise did not decrease systolic blood pressure in control and DOCA-salt rats but induced changes in liver activities of antioxidant enzymes, showing that exercise provoked liver oxidative stress in control and DOCA-salt rats. In comparison with our previous studies using spontaneously hypertensive rats, we conclude that the beneficial effects of chronic exercise on systolic blood pressure in rats are dependent on strain and the type of experimental hypertension.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
