title: The protective role of parsley extract against vincristine mutagenicity in Drosophila melanogaster.
abstract: In this study, Drosophila melanogaster males were treated with parsley plant extract and the anticancer drug vincristine (VCR) singly and in combined treatments (pre, co and post-treatments) to detect the mutagenic effects by using sex-linked recessive lethal test (SLRL) and estimation of cholinesterase enzyme (ChE) activities in order to compare the sensitivity of the two test systems. A wild type strain Oregon-R (Or-R) male flies of D. melanogaster were reared on a medium containing one concentration of each of VCR and parsley (4 ml/100 ml medium) in each single and combined treatment. Also the activity of ChE was estimated in some insects of the two generations: F1 females, F2 bar eye females (heterozygous) and F2 wild types males. The results indicate that both of parsley and vincristine did not cause significant increases of SLRL test in either the single or combined treatments. In contrast, estimation of ChE activities showed significant increase in all the broods within single and combination treatments, except female of the second generation of spermatid brood which treated with parsley and VCR at the same time. It is concluded that enzyme estimation is more sensitive than SLRL test for detection the mutagenic effect for parsley's extract and vincristine.
