title: [Tissue distribution of orthotolidine and pathways of its elimination].
abstract: Distribution of the carcinogenic agent orthotolidine (OT) in the rat's body has been investigated by diazotizing technique. Levels of free amines were 1.5-2 times those in control 3 days after the last administration (total treatment duration-8 months). Zymbal gland, the target tissue, showed the highest concentrations. Also, bound amine concentrations in Zymbal gland soared up (8 times those in control). Similar results were reported 7 days after the last administration of OT: free amine level in the same site was 7 times that in control. Enhanced free and bound amine concentrations may point to its being withdrawn through Zymbal gland ducts. This may also promote carcinogenesis in them.
