概要
BACKGROUND
Toxicity with paraquat can lead to serious damages to the liver.
OBJECTIVE
The study investigates the protective effects of Origanum vulgare leaf extract against paraquat liver damage.
METHODS
Rats were divided into six groups. Group 1, the control group; group 2, rats that received paraquat only; group 3, rats that received paraquat plus silymarin; and groups 4, 5, and 6 were treated with paraquat and O. vulgare leaf extract. Then, the serum and tissue parameters of the oxidative stress were examined.
RESULTS
In group 2, paraquat caused a remarkable increase in the level of serum ALT, AST, ALP, lipid profiles, and liver TNF-α gene expression compared to group 1. The groups which received O. vulgare leaf extract exhibited significant ameliorations in abnormalities of paraquat-induced liver damage and serum biochemical parameters.
CONCLUSIONS
O. vulgare leaf extract has inhibitory effects on paraquat-induced liver damage due to its antioxidant properties.
