Abstract:
:The effect of two polyamino-polycarboxylic acids, N-(2-hydroxyethyl) ethylenediamine triacetic acid (HEDTA) and diethylenetriamine penta-acetic acid (DTPA) and two thiol-chelating agents, sodium diethyldithiocarbamate (DDC) and dimercaptosuccinic acid (DMS) on the excretion of manganese (Mn) in rabbits given Mn i.p. was studied in order to investigate the affinity of this metal to N, O and S-containing compounds. HEDTA and DTPA were effective, and DDC and DMS were ineffective, in enhancing urinary and faecal excretions of Mn, indicating a greater binding capacity of Mn with chelators having N and O, than with those having S as electron donating centres.
