Combined Chelation Therapy with Deferasirox and Desferrioxamine In Removing Lead from Rats

Abstract

The present study aimed to evaluate the potential e fficiency of Deferasirox (DFX) and Desfferioxamine (DFO) as chelating agents in removing lead from rats as a biological model. Two different doses of lead (II) chloride (40 and 80 mg kg -1 body weight) were used for 45 days. After this per iod, all rats showed toxicity symptoms through loss of hair, greenish mottling on the live r, appearance of red dots around eyes and weakness. After lead administration, chelation therapy was done in removing the toxic metal from the biological system . The abilities of DFX and DFO chelators in removal of le ad from the body were studied for 10 days. Lead and iron concentrations in different tissues were measured b y Flame Atomic Absorption Spectroscopy (FAAS). Our results showed that two chelators can be more effec tive as combined therapy than as single therapy in removing lead from the body and also, toxicity symp toms are decreased. It could be concluded that DFX and DFO chelators could be used for the treatment of co mplication of lead intoxication symptoms.
