Protective effect of carvacrol against parathion treated cultured human peripheral blood lymphocytes.
| Treatments | Concentrations used (μg/mL + μg/mL) | Metaphase scored | SCE/cell ± SE |
|---|---|---|---|
| Control | Untreated | 50 | 2.46 ± 0.16 |
| Parathion | 2.5 | 50 | 5.63 ± 0.52a |
| Parathion + carvacrol | 2.5 + 2.5 | 50 | 4.33 ± 0.12b |
| Parathion + carvacrol | 2.5 + 5.0 | 50 | 3.07 ± 0.14b |
| Carvacrol | 2.5 | 50 | 2.56 ± 0.19c |
| Carvacrol | 5.0 | 50 | 2.86 ± 0.21c |
| DMSO (−ve control) | 20 | 50 | 2.32 ± 0.17d |
a P < 0.05 (significance as compared to untreated), b P < 0.05 (significant as compared to parathion treatment), c P > 0.05 (nonsignificance as compared to untreated), and d P > 0.05 (nonsignificance as compared to untreated).
