AVALIAÇÃO DA ATIVIDADE GENOTOXICA E ANTIGENOTOXICA de Euphorbia tirucalli (Aveloz).

Abstract

The use of medicinal plants, including extracts, of popular use as a therapeutic resource is a widespread trend in the Brazilian population. Euphorbia tirucalli is widely used by Brazilian popular medicine in the treatment of lesions, infectious diseases, tumors and inflammatory diseases. Through this work. Objective: To evaluate the genotoxic and antigenotoxic activity of Euphorbia tirucalli (aveloz). Methodology: Latex was obtained from a plant specimen, in the city of Goiânia, and diluted to the concentration of 1mg / ml. To evaluate the genotoxic and antigenotoxic activity of the aqueous solution of Euphorbia tirucalli latex were performed by the micronucleus test in the hematopoietic bone marrow of mice. The cytogenetic analysis of the slides was performed in order to detect possible chromosomal changes and / or losses (micronuclei) in the polychromatic erythrocytes of the bone marrow of the animals submitted to the different treatments. Results: In the treatments concomitant with the aqueous solutions of latex of Euphorbia tirucalli and Mitomycin C, there was a decrease in micronuclei numbers in 2000 EPC. The results allowed to conclude that the aqueous solutions of Euphorbia Tirucalli latex presented genotoxic, antigenotoxic, cytotoxic and anticitotoxic activity and the concomitant use of the aqueous solutions of the latex of Euphorbia tirucalli and Mitomycin C was not indicated, as the genotoxic and cytotoxic effects of MMC were decreased And thus not achieving the expected effect of this highly genotoxic agent.
