Twenty five female Wistar rats, 8 weeks old, were pre-injected with plutonium-239 in the right femoral muscles and divided into five groups; thereafter Rats of four groups were injected intraperitoneally with 30 mmol/kg of DTPP, CAP, LIHOPO or Ca-DTPA respectively, once per day for 3 days, beginning 1 hr after plutonium injection on the first day. The other one group was used a control. On day 4, rats were sacrificed to obtain organs and serum. Urinary excretion rate of DTPP was higher, and followed by Ca-DTPA, LIHOPO at the first day and decreased. Feces excretion rate of LIHOPO was higher than other agents for 3 days. CAP had no effect. Total amount of excreted Pu in urine and feces for 3 days of LIHOPO was higher, and followed by Ca-DTPA and DTPP. In the concentration of organs and serum were LIHOPO=DTPP
