^*Significantly (P < 0.05) lower uptake in lungs at 6 h after injection than at 2 h.

^†Significantly (P < 0.05) lower uptake in intestinal content after injection of 500 μg than after 1,000 μg.

^‡Significantly (P < 0.05) lower uptake in lungs at 24 h after injection than at 2 or 4 h.

Data are percentage injected radioactivity per organ (mean values and SD from all patients).
