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.

Ameliorative Effect

The effect of dietary lead exposure on immunomodulation of broilers and possible ameliorative effect of Andrographis paniculata were studied. One hundred broiler chicks were randomly divided into five equal groups of 20 each. Group T0 served as control while group T1, T2, T3 and T4 birds were provided commercial diet with lead acetate at the dose of 300 ppm in feed. Powder of dry leaves of Andrographis paniculata was mixed in the feed of group T2, T3 and T4 chicks at the dose of 2 gm, 3 gm and 4 gm/kg of feed respectively and fed for 4 weeks. Significant decrease in HI titres in T1 group and significant increase in T4 group suggested increased haemagglutination titre (HI) response. The maximum skin thickness and diameter on 24th and 48th hours was observed in control group birds (T0) and was comparable with T4 group. Microscopically spleen, thymus and bursa of fabricius revealed increase in lymphoid population in birds fed lead acetate along with Andrographis paniculata compared to T1 group. We concluded that Andrographis paniculata has immunomodulatory effect during lead toxicity in broilers.
