| Popis: | The distribution of colloids and labeled cells in organs is influenced by their intrinsic properties and by the state of the investigated subject. Iron deficiency remains an unsolved nutritional problem all over the world; one of its severe consequences is anemia. Because iron metabolism principally takes place in the liver, spleen, bone marrow, skeletal muscle and blood, we studied the effect of iron deficiency anemia on the biodistribution of 99mTc phytate, 99mTc gelatin colloid and 99mTc RBC (red blood cells labeled with 99mTc). Our results show that iron deficiency anemia modifies the pattern of biodistribution of the two colloids assayed. However, this behavior is different for both of them. This work contributes to studies that kinetically and statistically establish that iron deficiency anemia induces a significant inversion in the spleen-liver activity relationship when centellographic studies are performed with colloids such as 99mTc phytate. |
