abstract background and aim: increased rate of micronucleus in buccal mucosa cells and its correlation with carcinogenesis is worth consideration. recently, occupation in dental laboratories has been proposed as a predisposing factor. therefore, the present study aimed to evaluate the effect of occupational exposure on buccal mucosa cells of dental laboratory technicians. materials and methods:...
Cytochalasine B is an indicator in the CBMN assay, but can also be geno- or cytotoxic. The aim of study was to determine optimal dose cytochalasine for Cytokinesis-Block Micronucleus (CBMN) assay domestic cat. results revealed a surprisingly high number micronuclei (MN) relation doses used. It found that concentration 2.5 μg/ml enough obtain binuclear cells, with minimal toxic effect on lymphoc...
Dear Editor, I was very pleased to find that the article” Micronucleus Assay of Buccal Mucosa Cells in Waterpipe (Hookah) Smokers: A Cytologic Study “(1) has attracted the attention of some readers and has created a few points for them. In my opinion, these points are good bases to overcome some concerns regarding micronucleus assay.
background: stress may cause damages to dna or/and change the ability of the cells to overcome these damages. it may also cause irregularities in the cell cycle and induce abnormal cell divisions through glucocorticoid-dependent functions. the abnormal cell divisions, in turn, lead to chromosomal mal-segregation and aneuploidy. in this study, the effects of the stress hormone, hydrocortisone (h...
crude oil is enriched in polycyclic aromatic hydrocarbons (pahs). many pah analogs have proved to potentially damage dna. dna damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. in this research the comet assay and micronucleus (mn) test were used to detect dna damages and cytogenetic changes following crude oil expos...
conclusions b. oleracea demonstrated similar anti-inflammatory properties to omeprazole in rats with gerd. however, omeprazole also demonstrated genotoxic and cytotoxic effects in rats without gerd. results rats with gerd developed esophagitis and esophageal squamous cell carcinoma. b. oleracea and omeprazole-treated gerd rats presented significantly decreased inflammation in relation to non-tr...
background: radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (ir). in this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by cho-k1 cells. materials and methods: whole blood and cho-k1 cells were cultured in rpmi-1640 complete medium. cells were separately irradiated with...
