Olive leaf extract modulates permethrin induced genetic and oxidative damage in rats

Area of Science:

• Toxicology
• Environmental Health
• Natural Product Chemistry

Background:

• Permethrin is a widely used synthetic pyrethroid insecticide with known toxicity to humans and the environment.
• Previous research indicates permethrin exposure can lead to significant health concerns.
• Understanding protective agents against pesticide toxicity is crucial for public health and environmental safety.

Purpose of the Study:

• To evaluate the protective effects of olive leaf extract against permethrin-induced genotoxicity and oxidative stress in a rat model.
• To determine if olive leaf extract can modulate the adverse health impacts of permethrin exposure.
• To provide scientific evidence for the potential use of natural compounds in mitigating pesticide toxicity.

Main Methods:

• Rats were divided into four groups: control, permethrin-only, olive leaf extract-only, and combined permethrin and olive leaf extract.
• Genotoxicity was assessed using micronucleus and chromosomal aberration assays.
• Oxidative status was evaluated by measuring total antioxidant capacity and total oxidant status in serum samples.

Main Results:

• Permethrin treatment induced genotoxic damage and increased oxidative stress markers (total oxidant status) while decreasing antioxidant capacity.
• Olive leaf extract alone showed no adverse effects and increased antioxidant capacity.
• Co-administration of olive leaf extract significantly counteracted the genotoxic and oxidative damage caused by permethrin.

Conclusions:

• Olive leaf extract demonstrates significant protective properties against permethrin-induced genotoxicity and oxidative damage in vivo.
• This study provides the first evidence of olive leaf extract's ability to antagonize permethrin toxicity.
• Olive leaf extract can be considered a potential natural agent for mitigating the harmful effects of permethrin exposure.
