Abstract

It has been found that, besides ceroid-like pigment, the zymogen granules of the pancreatic exocrine portion, the ductules of the parotid gland, the stratum corneum of the skin, the hair cortex, and its external root sheath give a positive mercury-affinity reaction on paraffin sections. On the other hand, these tissues reveal a positive reaction when the colloidal iron method for SH radical is applied following pre-treatment with thioglycollic acid.
