Effects of Dihydroquercetin on Behavior of Albino Rat Offspring with Transgenerational Chemical Body Burden
Introduction. Lead pollution is a common environmental problem. Having no physiological functions, this toxicant has a negative polytropic impact on a body, including neurotoxic, reproductive, and transgenerational effects. The mechanism of lead toxicity is oxidative stress. Flavonoids have active antioxidant properties. They are widely represented in plant foods, are able to restore protective capabilities of cells and have chelating properties with respect to lead. One of the representatives of this group of substances is dihydroquercetin. The objective was to study the effect of dihydroquercetin on behavior of rats with hereditary chemical body burden exposed to lead at 60 mg/ kg during 25 days. Materials and methods. We studied the behavior of rat offspring in an open field and established their blood lead levels by electrothermal atomization atomic absorption spectrometry. For statistical processing the U-Mann - Whitney test was used. Results. In the present experiment, the effect of lead on the offspring of male albino rats exposed to 60 mg/kg of lead for 25 days caused changes in the activity of animals in the open field. The severity of changes was more pronounced in animals with a hereditary chemical body burden. These animals showed a decrease in orientation and physical activity and increased anxiety. In rats with a hereditary burden, changes in behavior were detected when administering dihydroquercetin. The activity of animals demonstrated a positive dynamics: we observed a statistically significant increase in physical activity and orientation. The number and duration of behavioral acts approached control values. Conclusions. The revealed effects of lead on the offspring of albino rats with a transgenerational chemical body burden require further study to understand the mechanism of the phenomenon.
