Antimutagenic Activity of Cassia Auriculata Linn Fractions along with Anticancer Activity in Male Albino Mice

Background: In recent years, there has been a surge in interest in studying plant-derived materials and their impact on DNA. Herbal products include a number of natural substances that may help protect cells against mutagen-induced cell damage. Aim: The purpose of this research was to assess the genotoxic effects of Cassia Auriculata Linn flavonoids (CAF) and Cassia Auriculata Linn saponin (CAS) rich fractions on mouse bone marrow cells utilizing chromosomal aberration test and micronucleus assay. Methodology: The suppressive impact of CAF and CAS on 7, 12-dimethylbenz (α) anthracene (DMBA) and Croton oil induced skin tumor promotion in mice with topical administration twice weekly for 18 weeks is also investigated in this work. Three dosages of 100 and 200 mg/kg body weight were used. Single oral dosages of CAF and CAS Fraction at the three levels did not enhance the number of micronucleate polychromatic erythrocytes in the micronucleus experiment. Result: In mice bone marrow cells, a single oral treatment of CAF and CAS fraction revealed no significant alterations in mitotic indices or chromosomal aberration induction. The clastogenicity of CYP was considerably decreased by pretreatment with CAF and CAS fraction. As a result, it can be stated that CAF and CAS fraction had no genotoxic impact on mouse bone marrow cells. Conclusions: The portions of Cassia Auriculata have been shown to be non-genotoxic and non-clastogenic at the quantities utilized in this investigation. CAF and CAS Fraction might possibly be a promising skin tumor promotion reducing agent, according to this research.

Genotoxicity of aluminium oxide, iron oxide, and copper nanoparticles in mouse bone marrow cells

The aim of this study was to evaluate the genotoxic effects of Al2O3, Fe2O3, and Cu nanoparticles with chromosomal aberration (CA), micronucleus (MN), and comet assays on the bone marrow of male BALB/c mice. Three doses of Al2O3, Fe2O3 (75, 150, and 300 mg/kg), or Cu (5, 10, and 15 mg/kg) nanoparticles were administered to mice through intraperitoneal injection once a day for 14 days and compared with negative control (distilled water) and positive control (mitomycin C and methyl methanesulphonate). Al2O3 and Fe2O3 did not show genotoxic effects, but Cu nanoparticles induced significant (P<0.05) genotoxicity at the highest concentration compared to negative control. Our findings add to the health risk information of Al2O3, Fe2O3, and Cu nanoparticles regarding human exposure (occupational and/or through consumer products or medical treatment), and may provide regulatory reference for safe use of these nanoparticles. However, before they can be used safely and released into the environment further chronic in vivo studies are essential.
