ABSTRACT
Porphyrin-fulleren-based nanoparticles (NP), containing magnetic isotopes 25Mg, 67Zn and zinc of natural isotope composition (Zntotal-NP), have been tested on leukemic cells of patients with T-ALL, B-ALL, AML and lymphocytes of healthy donors. Reliable differences in action of magnetic and non-magnetic zinc isotopes for some types of cells were obtained. Magnetic magnesium isotopes and pure nanoparticles of porphyrinfulleren did not demonstrate any effects. 67Zn-NP induced high cytotoxicity in cells of acute B-lymphoblastic leukemia with LD50 almost three times lower, than those for healthy donors, and 4 times lower in comparison with Zntotal-NP. Also evaluation of apoptosis process in granulocytes of healthy donors in the case of the preparates were performed by method of flow cytometry.
