Administration of HgCl2 at a dose of 5 mg/kg body weight/day for 15 days to male albino rats brought about a marked depression of the scavenging enzymes viz. glutathione peroxidase and glutathione S-transferase, in kidney. There was an adaptive rise in the levels of catalase and no increased lipid peroxidation was observed. The levels of both glutathione and glutathione reductase were decreased, whereas total thiol increased. In the intoxicated rats, Vitamin-E was effective in bringing back glutathione levels to normal. The adaptation in this group of animals is reflected by increased superoxide dismutase activities. Feeding of Vitamin-E alone could cause a depression of the scavenging enzymes like glutathione peroxidase and glutathione S-transferase along with a slight lowering of glutathione levels.

Vitamin-E-loaded nanoemulsion (Vit E-NE) was produced, and the effects of repeated oral administration of Vit E-NE (2 g/kg/day) for five days on hepatic gene expression and serum metabolites were investigated in rats. The mean particle diameter and zeta potential of Vit E-NE was 112 nm and 56 mV, respectively. Vit E-NE administered rats showed significantly higher triglyceride content than of standard diet (control) or Vit E control emulsion (Vit E-CE) group but no toxicity symptoms were found in blood biochemical analysis. Next generation sequencing analysis of rat liver revealed that several genes related to energy and xenobiotic metabolism (CYP1A1 and glutathione S-transferase) were significantly altered. Serum metabolites (B-hydroxybutyrate and palmitoleic acid) indicating ketone body production and activation of stearoyl-CoAdesaturase were significantly increased by administration of Vit E-NE. The results of this study suggest that excessive consumption of edible nano-sized food ingredients can possibly cause adverse effects.
