| Popis: | Nonheme iron indices in the blood and brain tissues have been determined in a group of patients bearing glial brain tumours by quantitative electron spin resonance spectroscopy. Hyperferremia (statistically significant increase in transferrin iron concentration in the blood and plasma as well as in transferrin saturation in the blood relative to the reference data) and also an increase in ferritin iron concentration in the tumour and peritumoral brain tissue relative to respective values determined in the blood and in the adjacent apparently normal brain tissue are characteristics of malignant glial brain tumours in human beings. The revealed peculiarities of nonheme iron metabolism point to the new potentially useful approaches to glial brain tumour diagnosis using a set of iron exchange parameters and therapy using iron chelators as promising antiprolifirative agents. The question have to be arisen about iron overload as a risk factor for glial brain tumours in human beings and the genetic predisposition for glial brain cancer associated with homoor heterozygosity at the HFE locus. |
