The goal of this study was to compare the cytotoxic and genotoxic effects of plutonium-239 alpha particles and GSM 900 modulated mobile phone (model Sony Ericsson K550i) radiation in the Allium cepa test. Three groups of bulbs were exposed to mobile phone radiation during 0 (sham), 3 and 9h. A positive control group was treated during 20min with(More)
Biomarkers of oxidative stress such as catalase (CAT), glutathione S-transferase (GST), glutathione reductase (GR) activity, and malondialdehyde and reduced glutathione content, as well as heavy metal concentrations (HM: Pb, V, Cr, Mn, Co, Ni, Cu, Zn, and Cd), were studied in Dreissena polymorpha tissues. Mussels were collected on three sites located on the(More)
We analyzed mutagenic and mitosis-modifying effects of silver nanoparticles (Allium test). Chromosome aberrations and laggings and micronuclei were simultaneously registered in the same sample. Mitotic and phase indexes were calculated. No mutagenic effects were detected after treatment with silver nanoparticles in doses of 1.0, 2.5, 5.0, and 50 mg/liter.(More)
The mutagenic and antimitotic activities of the standard antituberculosis drug isoniazid and the immunomodulatory drug tubosan were compared using the Allium test, which took into account the frequency of chromosome aberrations, chromosome lagging, and micronuclei and allowed the mitotic and phase indices to be determined. It was established that isoniazid(More)
