Effect of mixed ligand complex therapy on the retention of 95Nb and 144Ce in mice.

We have examined in mice the effects of mixed ligand treatments with desferrioxamine B (DFOA), Na3Ca-diethylenetriamine pentaacetic acid (DTPA), and DL-penicillamine (PA) on the retention of a mixture of 95Nb and 144Ce. The results show that 95Nb + 144Ce could be mobilized effectively by simultaneous application of specific agents (i.e.

Effect of 60Co-Gamma whole body irradiation and treatment with radioprotector on the retention of 144Ce, in mice.

In animal experiments the effects of 7.5 Gy whole-body irradiation (LD50/30) and/or of radioprotecting compound (WR-2721) on the retention and elimination of 144Ce were investigated. It was stated that in the first three days there was an increase in the deposition of 144Ce after whole-body irradiation and upon treatment with radioprotective compound WR-2721.

Influence of mixed-ligand complexes on retention and distribution of radioniobium in mice.

The individual effects of desferrioxamine B (DFOA), Na3Ca diethylenetriaminepentaacetic acid (DTPA), Na-salicylate, DL-penicillamine, and 2-aminoethylisothiouronium bromide hydrobromide, as well as the effect of mixed-ligand treatment on the retention and elimination of 95Nb in mice have been examined. It was found that 95Nb could easily be mobilized by a single dose of DFOA, but the best result was obtained with the DFOA and DTPA combination. Mixed-ligand treatment did not change the deposition characteristics and translocation kinetics of 95Nb.
