Protective and prophylactic effects of chlorogenic acid on aluminum-induced acute hepatotoxicity and hematotoxicity in mice

- Chlorogenic acid (CGA) prevented increase of osmotic fragility in Al treated mice.
- CGA attenuated Al-induced oxidative stress and histological degeneration in liver.
- CGA can decrease the level of Al in liver and blood of the Al-treated mice.
- CGA supplementation may be favorable to avoid Al-induced biototoxicity for humans.

The possible health impact of the exposures to Al from environment would be inevitable for humans. Using chelating agents and natural antioxidants against Al-induced biotoxicity become a natural and modern way to prevent the adverse effects of Al in people. This study was undertaken to determine the effectiveness of chlorogenic acid (CGA, 5-O-caffeoylquinic acid) in preventing aluminum chloride (AlCl3) induced hepatotoxicity and hematotoxicity in mice. Control, Al-treated (a single injection of 25 mg Al3+/kg, i.p.), Al + CGA (2 h after, a single dose of 100 mg/kg, i.p.), CGA + Al (administered to mice daily for 5 days at 30 mg/kg before Al-treatment) and group of CGA per se (administered to mice daily for 5 days at 30 mg/kg) were used. The levels of Al in liver and blood, the activities of transaminases in serum and osmotic fragility were increased by comparison with the control, while the activities of superoxide dismutase and catalase decreased significantly in the Al-treated group. However, treating mice with CGA at either dosing regimens, post- or pre- Al administration alleviate Al oxidative damaging effects, stabilize cell membrane, prevent hepatocyte apoptosis. CGA supplementation may be favorable to avoid Al-induced hematotoxicity and hepatotoxicity for humans.
