Effects of Cholinergic Stimulation with Pyridostigmine Bromide on Chronic Chagasic Cardiomyopathic Mice

Figure 6

Immunohistochemistry for parasite antigens. Photomicrographs from left ventricular sections stained with T. cruzi antigens by peroxidase reaction. Panels (a) and (d): control nontreated mouse. Panels (b) and (e): chagasic nontreated mouse. Panels (c) and (f): chagasic mouse treated with pyridostigmine bromide. Top panels: magnification = 100x; bottom panels: magnification = 200x. Note the gray color labeling T. cruzi antigens throughout the sections in Panels (b), (c), (e), and (f).
