Background: Onopordum carduiforme, Centaurea verutum, and Achillea santolina are medicinal plants grown in Syria and commonly used in traditional medicine. Such as antibacterial, antioxidant and anticancer properties. However, the genotoxic effects of these plants have not been studied. Aim and objective: the aim of this study was to evaluate the genotoxic effects of hydroethanolic extracts of these plants on human lymphocyte cultures model by evaluating the cell proliferation, determination of mitotic index (MI), and their effects on chromosomes. Methods: the hydroethanolic extracts of the aerial parts of the three plants were extracted using an Ultrasonic bath. Then the genotoxic effects of hydroethanolic extracts of these plants on human lymphocyte cultures was conducting by determination of mitotic index (MI). Results: the results showed that all three plants decreased non-significantly the mean of mitotic index in comparison with negative control (normal MI) (p>0.05) at concentrations (1, 3, 5 mg/ml) and the mitotic index values ranged was between (2.25±0.07 and 3.3±0.28). However, C. verutum showed the lowest mitotic index (3±0.14 at 1 mg/ml) and (2.25±0.07 at 5 mg/ml), and did not induce chromatid or chromosome breaks or gaps. Conclusion: these preliminary results on cytotoxicity and mutagenicity of these plants provide valuable information about the safety of using them in alternative medicine.                    Peer Review History: Received: 11 November 2021; Revised: 13 December; Accepted: 28 December, Available online: 15 January 2022 Academic Editor:  Dr. A.A.

Abstract In this investigation, the genotoxic properties of mestranol were examined in vitro. Human lymphocyte cultures were exposed for 72 h to mestranol at concentrations of 7.5, 15 and 30 µg/g. The genotoxic effects of the chemosterilant were assessed by numerical and structural chromosome aberrations. Mestranol induced certain genotoxic effects in human lymphocytes. There was a dose-dependent significant (p<0.01) increase in the number of numerical aberrations in comparison to the control, but without significant differences (p>0.05) between the doses applied. Further, structural aberrations increased significantly (p<0.01) in the presence of mestranol, being most frequent in cultures exposed to the highest mestranol dose. The frequency of Robertsonian translocations increased significantly only in cultures treated with mestranol at concentration of 30 µg/g in comparison both with the control (p<0.01) and the lowest chemosterilant dose (p<0.01). There were significant differences (p<0.01) in the levels of chromosome gaps and fragments compared to Robertsonian translocations, whilst the frequencies between gaps and fragments were not significantly different (p>0.05).

Abstract The aim of this study was to investigate the in vitro genotoxic effects of the anticancer drugs fotemustine and vinorelbine on human lymphocytes and to determine individual and sex-related responses to these drugs. Fotemustine is a DNA-alkylating drug while vinorelbine is a semi-synthetic Vinca alkaloid. The study was carried out with twenty independent healthy donors for each drug. We have tested the ability of these drugs to induce chromosome aberrations (CAs) and sister chromatid exchanges (SCEs) as well as effect on the mitotic index (MI) in cultured human lymphocytes. Fotemustine was shown to induce CAs and SCEs at all concentrations tested (2, 4 and 8 μg/ml) in a dose-dependent manner. Additionally it also decreased the mitotic index in a similar dose-dependent manner. Vinorelbine had no effect on structural CAs, but it significantly increased the numerical CAs at all doses tested (0.5, 1 and 2 μg/ml). Vinorelbine also induced SCE events and increased the MI values. Two-way analyses of variance were used to compare the individual and gender-related susceptibilities to fotemustine and vinorelbine with respect to the CA, SCE and MI values. The results indicated that individuals in fotemustine treatment groups showed different genotoxic responses with respect to CA and SCE induction and additional findings indicated a gender-specific response in this group. Individuals in the vinorelbine test group also exhibited statistically significant numerical CA, SCE and MI responses to vinorelbine. A statistically significant gender-related SCE response to this drug was also evident. This study indicates that these drugs have potentially harmful effects on human health.

Micromeria pulegium (Rochel) Benth. is an endemic species of Lamiacea family that includes frequently used plants in culinary and folk medicine. As cytotoxic potential of some species of Micromeria genus has been confirmed, this study aimed to test unknown antiproliferative and genotoxic potential of M. pulegium, endemic bh species, aqueous leaf extract in normal (human lymphocytes) and cancer (human melanoma GR-M) cells in order to protect small populations of native M. pulegium populations or promote its controlled micropropagation or cultivation. Cytokinesis-block micronucleus cytome assay was applied for human lymphocyte cultures, while trypan blue exclusion assay was used for evaluation of cytotoxicity in human GR-M melanoma cells. Results demonstrate no genotoxic effects up to concentration of 0.2 mg/ml in human lymphocyte in vitro but significant reduction of cell viability in human GR-M melanoma cell line cultures treated with 0.3 mg/ml of Micromeria extract.

AbstractThis study evaluated direct and metabolic genotoxic effects caused by Lannate-90®, a methomyl-based formulation (90 % active ingredient), in human lymphocyte cultures using sister chromatid exchange assay (SCE). Two processes were used for the plant promutagens evaluation: in vivo activation, applying the insecticide systemically in plants for 4 h and subsequently adding plant metabolites containing extracts to lymphocyte cultures; and in vitro activation, where the insecticide was incubated with Vicia faba S10 mix plus human lymphocyte culture. Direct treatment with the insecticide significantly increased SCE frequency in human lymphocytes (250-750 mgL−1), with cellular death observed at 1000 mgL−1 concentration. Using the extracts of Vicia faba treated with Lannate-90® to treat human lymphocytes, a dose-response relationship was observed. In lymphocyte cultures treated directly with the insecticide for 2 h, a negative response was obtained. When S10 mix was added, SCE frequency did not change significantly. Meanwhile, a mixture of S9 mammalian metabolic mix and Lannate-90® increased the SCE frequency, with an observed concentration-dependent response. Although Lannate-90® induced cellular death at the highest concentrations, it did not cause a delay in cell proliferation in any of the treatments, confirming its genotoxic action. This study is one of the first to evaluate and compare the direct effect of Lannate-90® in two bioassays, animal and vegetal, and the effect of plant and animal metabolism on its genotoxic potential.

Tritiated Thymidine Uptake

The action of dichlorvos (2.2-dichlorovinyldimethyl phosphate) was studied with a short-term in vitro system which utilizes human lymphocytes. The parameters studied were the action exerted by the pesticide on scheduled (semiconservative) and unscheduled (reparative) DNA synthesis measured as tritiated thymidine uptake. The results obtained show that dichlorvos affects semiconservative DNA synthesis, damages human lymphocyte DNA inducing low reparative synthesis, and interferes with DNA repair processes after damage exerted by ultraviolet rays.
