Purification, Characterization and Evaluation of the Antitumoral Activity of a Phospholipase A2 from the Snake .

Nature presents a wide range of biomolecules with pharmacological potential, including venomous animal proteins. Among the protein components from snake venoms, phospholipases (PLA) are of great importance for the development of new anticancer compounds. Thus, we aimed to evaluate the PLA anticancer properties from venom.

Potential role of zinc in the visceromegaly regression and recovery of hematological parameters during treatment of visceral leishmaniasis in children from an endemic area.
