Eugenol Attenuates TiO2 Nanoparticles-Induced Oxidative Damage and Toxicity

Strategic Insights -

Research conducted at the Aligarh Muslim University in India has found that eugenol, a dietary antioxidant, can mitigate the toxic effects of titanium dioxide (TiO2) nanoparticles on rats. The study, published in the Environmental Science and Pollution Research journal, exposed adult male Wistar rats to TiO2 nanoparticles and observed significant oxidative stress, liver and kidney damage, and DNA damage. However, co-treatment with eugenol significantly reduced these effects, suggesting its potential as a chemoprotective agent against TiO2 nanoparticle-induced toxicity.

Key Takeaways:

  • The study exposed adult male Wistar rats to TiO2 nanoparticles (150 mg/kg body weight) by intraperitoneal injection (i.p.) and observed significant oxidative stress, liver and kidney damage, and DNA damage.
  • Co-treatment with eugenol (1-10 mg/kg body weight) reduced the toxic effects of TiO2 nanoparticles, including oxidative stress, liver and kidney damage, and DNA damage.
  • The study concluded that eugenol can be used as a chemoprotective agent against TiO2 nanoparticle-induced toxicity.
  • The research was carried out in vivo, using adult male Wistar rats, and observed the effects of TiO2 nanoparticles and eugenol co-treatment on the rats' organs and DNA.
  • The study demonstrated the potential benefits of eugenol in mitigating the toxic effects of TiO2 nanoparticles, which are commonly used in food, edible dyes, and other commercial products.

Statistics:

  • The study used 14 days to observe the effects of TiO2 nanoparticles and eugenol co-treatment on the rats.
  • The TiO2 nanoparticles were administered at a dose of 150 mg/kg body weight, while the eugenol was administered in doses ranging from 1-10 mg/kg body weight.
  • The study observed a significant increase in hydrogen peroxide levels in the liver, kidney, and spleen of treated rats, indicating oxidative stress.
  • The study also observed a significant decrease in glutathione level and antioxidant enzyme activity in the kidney, liver, and spleen of treated rats.
  • The study used inductively coupled plasma mass spectrometry to analyze titanium (Ti) accumulation in various tissues.
