title: Oral Zn-DTPA treatment reduces cadmium absorption and retention in rats.
abstract: This work was performed to evaluate the possibility of using early oral diethylenetriaminepentaacetate (DTPA) therapy for decreasing absorption and retention of cadmium. Albino rats (6 days and 6 weeks old) were used. 115mCd was administered orally. Zn-DTPA was also given orally (3.64 mmol/kg) immediately after 115mCd and 24 h thereafter. Radioactivity in body and organs was determined 6 days later. In sucklings this treatment decreased whole body and gut retention 7-9 times and kidney and liver retention 2-3 times. In older rats it decreased whole body, gut and organ retention 4-5 times. This finding deserves attention since it is generally believed that DTPA is not indicated for early treatment, i.e. while the toxic metals or radionuclides are still in the gastrointestinal tract.
