Mitigating properties of vitamin E and olive oil on the teratomorphogenic impacts of lambda-cyhalothrin in developing...

Embryonic toxicity of lambda-cyhalothrin (LCH) and the mitigating properties of extra virgin olive oil (EVO) and vitamin E were investigated in golden black variety of chick embryos. Fifty fertilized eggs distributed in 5 groups received their respective group treatments at zero days of incubation were recovered after 14 days of incubation and fixed in fixative for 48 h for further studies. Results showed that treatment with LCH caused embryonic death, growth retardation and developmental abnormalities such as limbic developments, reduced muscular growth, and embryonic cataract. Post treatment with vitamin E and EVO alone significantly improved all these developmental defects. Morphometric readings also showed that embryos treated with combined dose of vitamin E and EVO had more resemblance towards the control group embryo. These findings suggested that the use of vitamin E and EVO together during pregnancy have the potential to curtail these accidental, environmental and work place exposures of LCH.
