PURPOSE The present study was an attempt to determine the spontaneous frequency of micronuclei (MN) in newborns from High Level Natural Radiation Areas (HLNRA) and the adjoining Normal Level Radiation Areas (NLNRA) of the monazite-bearing Kerala Coast in Southern West India using Cytochalasin Blocked Micronuclei (CBMN) assay. MATERIALS AND METHODS Human umbilical cord blood samples were colle...

Fish have defense systems that are capable of repairing damages caused by xenobiotics like benzo[a]pyrene (BaP), so the aims this study were to identify BaP toxicity in melanomacrophages (MMs) cytoskeleton, evaluate melanin area MMs, and analyze genotoxicity. Rainbow trout juveniles (n = 24) split 48h 7d treatments received 2 mg/kg BaP. After experiment, blood samples collected liver was remove...
Background: A radioprotective effect of amifostine as well as its ability to modulate the level of spontaneous and gamma-irradiation-induced genetic changes on human peripheral blood lymphocytes has been investigated . Amifostine, known as a potent radical scavenger, has been introduced as the most effective radioprotector, yet it is not completely approved for the clinical use. However, furt...
Background: The purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. Materials and Methods: Human peripheral blood lymphocytes were irradiated using proton beams (LET: 34.6 keV μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (CB) micronucleus (MN) assay. To determine th...
INTRODUCTION In the past decades, several authors have investigated the genotoxicity caused by exposure to chemicals, but there are no reports on studies analyzing such effects on children in Argentina. The objective of this study was to establish the micronucleus frequency in exfoliated buccal mucosa cells in children from urban areas with environmental exposure (through inhalation) and to com...
Anti-Genotoxicity Evaluation of Cratoxylum Formosum Dyer Leaves by Comet Assay and Micronucleus Test
Cratoxylum formosum Dyer is the Thai vegetable which commonly consumed a fresh leaves. In this study, we extracted Cratoxylum formosum with water and tested the extract for genotoxicity and anti-genotoxicity effects. We carried out the experiment using micronucleus test and comet assay in TK6 cells. In micronucleus experiment, we used cytokinesis-block proliferation technique to stop cell divis...
