The effects of zinc and metal alloy (Cu, Zn, and Fe) nanoparticles on transplantation capacity of tumors (mouse sarcoma 37, rat sarcoma 45 and Pliss lymphosarcoma) and the levels of exogenous Zn in tumor and non-tumor tissues of mice were studied. Preincubation (30 min, 37°C) of sarcoma 37 cells with zinc nanoparticles and sarcoma 45 with alloy… (More)
The effects of short single-walled carbon nanotubules functionalized by COOH- and NH2- containing groups (NT-COOH and NT-NH2), on the dynamics of transplanted Pliss lymphosarcoma growth were studied after tumor cell preincubation with nanotubules and after injection of nanotubules into the developing tumor. Tumor growth was inhibited and the lifespan of… (More)
Metal (Zn, Cu, Fe) nanoparticles, particularly Zn, induce regression of transplanted sarcoma 37 and increase the percentage of dead and degenerated cells. Antitumor effect of metal nanoparticles was not associated with leukopenia or coarse bone marrow abnormalities, but differential leukocyte and bone marrow counts remained changed.
