Abstract

The usages of medicinal plants as therapeutic agents have been practiced in a large scale of applications that make studies of their mutagenicity and/or anti-mutagenic /anti-carcinogenic effects very essential. The current investigation is focused on the anti-mutagenic effects of the Tamarix nilotica (Ehrenb) crude extract using chromosomal aberrations analysis in mice bone marrow. In fact, a single plant may have diversity of phytochemicals ranging from bitter compounds that stimulate digestive system, phenolic compounds for antioxidants and many other pharmacological properties, antibacterial, and antifungal, tannins that work as natural antibiotics, diuretic substances and alkaloids, etc. Tamarix is represented in Egypt with two indigenous species which are Tamarix aphylla (L.) (H.Karst) and T. nilotica (Ehrenb.) Bunge (T. nilotica (Ehrenb.). In addition, it was used in Egyptian traditional medicine as an antiseptic agent. Extracts of Tamarix species have been widely used in traditional medicine in Asia and Africa mainly for their antiseptic, astringent, diaphoretic and diuretic properties. The current investigation is focused on the anti-mutagenic effects of the Tamarix nilotica crude extract using chromosomal aberrations analysis in mice bone marrow. Mitomycin C (MMC) was administered to mice as a positive control alone before and after treatment with 5 or 0.5 mg/ kg b.wt Tamarix crude extract as acute (24 and 48 h) and sub-acute (15 consecutive days) doses respectively. Results indicated that the Mitomycin C (MMC) exposure induced statistically significant increase in chromosomal aberrations compared to the control, however T. nilotica revealed slight insignificant effect on aberrant mitosis rate. Chromosomal aberration domain structural and numerical aberrations.
The frequency of chromosomal aberrations (CA) and mitotic index (MI) decreased with increasing the dose and time of T. nilotica treatment, especially pre-treatment (plant + MMC). This effect was found to be dose-dependent. In conclusion, the results showed that T. nilotica could be considered as a good anti-mutagenic agent.
