ABSTRACT
Evaluating the effect of infusion Cunila microcephala Benth on acetylcholinesterase activity (AChE) enzyme and on biomarkers of oxidative stress in farmers erythrocytes. We used samples from 16 rural workers exposed to pesticides for a minimum of five years, and a control group composed of 16 individuals not exposed to pesticides. The erythrocytes of farmers and from group A were exposed “in vitro” the saline solution (NaCl 0,9%). The other groups were exposed to the infusion of “poejo” at concentrations of 0; 5; 10; 25 and 50 g/L (Groups B, C, D and E, respectively). Then, it was realized the analitical determinations of AChE activity and TBARS, PCs and GSH levels. The results showed that “poejo” infusion 50g/L, increased the AChE activity and GSH levels. However, the TBARS e PCs levels decreased after the treatment with “poejo” infusion 25 e 50 g/L. The “poejo” infusion 50 g/L is able to revert “in vitro” the inhibition of AChE activity that occurs by exposure to pesticides and also demonstrates an important antioxidant potential, given that decreased lipid and protein damage and also it stimulated the production of the main non-enzymatic antioxidant endogenous.
