Light microscopy images of peripheral nerves at 40x magnification, Masson’s trichrome staining.
A Normal appearance of myelin on Masson’s trichrome; myelin sheaths stain purple-red (black arrow). B Section of treated peripheral nerve at the center of the lesion showing absence of purple-red staining (arrow) indicating acute damage to the myelin sheaths. Asterisk (*) indicates subperineural edema.
