background: critical macromolecules of cells such as dna are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. selenium and vitamin-e are natural compounds that have been shown to be a direct free radical scavenger. the aim of this study was to investigate the radioprotective effect of selenium and vitamin-e separately and sy...
The influence of genetic polymorphisms in GSTM1 and GSTT1 genes on micronucleus frequencies in human peripheral blood lymphocytes was assessed through a pooled analysis of data from seven laboratories that did biomonitoring studies using the in vivo cytokinesis-block micronucleus assay. A total of 301 nonoccupationally exposed individuals (207 males and 94 females) and 343 workers (237 males an...
The micronucleus and nuclear abnormalities assays have been used increasingly to evaluate genotoxicity of many compounds in polluted aquatic ecossystems. The aim of this study is to verify the efficiency of the micronucleus assay and nuclear abnormality assay in field and laboratory work, when using erythrocytes of the tropical marine fish Bathygobius soporator as genotoxicity biomarkers. Gill ...
The environmental impact of metal complexes such as organotin(IV) compounds is of increasing concern. Genotoxic effects of organotin(IV) compounds (0.01 mug/ml, 0.1 mug/ml or 1.0 mug/ml) were measured using the alkaline single-cell gel electrophoresis (comet) assay to measure DNA single-strand breaks (SSBs) and the cytokinesis-block micronucleus (CBMN) assay to determine micronucleus formation....
The use of artificial implants provides a palliative or permanent solution for individuals who have lost some bodily function through disease, an accident or natural wear. This functional loss can be compensated for by the use of medical devices produced from special biomaterials. Titanium alloy (Ti-6Al-4V) is a well-established primary metallic biomaterial for orthopedic implants, but the toxi...
Fluphenazine, an antipsychotic drug that belongs to the phenothiazine family, reduced the genotoxicity of direct- and indirect-acting mutagens in the Ames test, both in the presence and in the absence of promutagen-activating S9 fraction. In short-term tests on human lymphocytes, the inhibitory effect of fluphenazine on the genotoxicity of standard mutagens was strongest in the cytokinesis-bloc...
