چکیده مقاله:

Background and Objective: Lead entry into the body causes considerable damages to the brain in the long term. We aimed to investigate the effects of exercise (treadmill running) and flaxseed oil on lead acetate-induced behavioral deficits in male rats.  Materials and Methods: 60 rats were divided into 6 groups: Control (C), Exercise (Ex), Flaxseed oil (FO), Lead (L), Lead- Exercise (L-Ex), and Lead- Flaxseed oil (L-FO). Groups L, L-Ex, and L-FO obtained 100 mg/kg of lead acetate, and groups FO and L-FO received 4 ml/kg (by gavage) of flaxseed oil for 28 consecutive days and Ex, and L-Ex groups ran on the treadmill. At the end of the session, spatial memory, depression, and anxiety behaviors were examined utilizing Morris water maze, forced swimming test, and elevated plus maze respectively.  Results: Lead acetate impaired learning and memory and led to depression and anxiety in rats. Treadmill running and flaxseed oil, both, improved learning and memory and decreased anxiety, but unlike treadmill running, flaxseed oil could not prevent depression resulted from lead consumption. Conclusion: Exercising (treadmill running) and flaxseed oil prevent lead-induced behavioral deficits.

  Objective(s): ABC transporters comprise a large family of transmembrane proteins that use the energy provided by ATP hydrolysis to translocate a variety of substrates across biological membranes. All members of the human ABCG subfamily, except for ABCG2, are cholesterol-transporter.

Protective role of flaxseed oil against lead acetate induced oxidative stress in testes of adult rats

Even though the toxic effects of lead compounds had been studied over many years, inconsistent results have been obtained about their oxidative stress in the testes of adult rats. Lead acetate (20 mg/kg) alters the histology of testes as well as enhances lipid peroxidation and nitric oxide production in both serum and testes with concomitant reduction in glutathione (GSH) and antioxidant enzyme...

Heritability of treadmill running endurance in rats.

Treadmill running was evaluated as a phenotype for selective breeding for high- and low-endurance performance from a starting population of 18 male and 24 female outbred Sprague-Dawley rats. Each rat was exercised to exhaustion once per day for 5 consecutive days. The treadmill was set at a constant 15° slope, and the initial velocity of 10 m/min was increased by 1 m/min every 2 min. The total ...

Treadmill exercise alters histone acetylation differently in rats exposed or not exposed to aversive learning context.

Epigenetic modifications have been linked to memory formation after learning context exposure and to exercise effects on memory performance. The aim of this study was to investigate the effect of treadmill exercise (20 min/day during 2 weeks) on H3K14 acetylation and H3S10 phosphorylation levels in the hippocampi of 3-month-old Wistar rats exposed and not exposed to aversive learning context. M...
