Morphological changes of U-937 Human macrophage cell line after exposure to Crotalus adamanteus venom at different concentrations. (Ctrl) macrophage supplemented with medium without any treatment served as control; (PC), cells exposed with ceftazidime as a positive control. Macrophages were incubated with venom at different (0.05–10 mg/mL) concentrations (Other photos not shown).
