The aim of the letter to editor is to provide some comments regarding the manuscript of DehghanNezhad et al.(1) recently published in the Iranian Journal of Pathology titled “Micronucleus Assay of Buccal Mucosa Cells in Waterpipe (Hookah) Smokers: A Cytologic Study.” In this article, the authors were able to detect high frequencies of micronucleus in buccal mucosa cells of waterpipe smokers whe...

Los herbicidas están siendo abundantemente utilizados haciendo que los mismos no solo lleguen al organismo específico sino también contaminen el medio ambiente donde son empleados. El herbicida 2,4-D es en la actualidad uno de agroquímicos más utilizado agricultura. peces blanco contaminación, éstos estar contacto con tóxicos desarrollan posteriormente alteraciones pueden ser estudiadas, por lo...

A replicate evaluation of increased micronucleus (MN) frequencies in peripheral lymphocytes of workers occupationally exposed to formaldehyde (FA) was undertaken to verify the observed effect and to determine scoring variability. May-Grünwald-Giemsa-stained slides were obtained from a previously performed cytokinesis-block micronucleus test (CBMNT) with 56 workers in anatomy and pathology labor...

The aim of this study was to investigate the genotoxic effects of flunixin meglumine on mice peripheral lymphocytes by in vitro and in vivo/invitro cytokinesis block micronucleus tests (CBMN). Flunixin meglumine was used at concentrations of 25, 50 and 100 μg/mL for the in vitro assay and 50, 75 and 100 mg/kg for the in vivo/in vitro assay. Mice were treated intraperitonally twice with a 24 h i...

Arruva, the R,R-isomer of monatin (sodium/potassium 2R,4R-2-amino-4-carboxy-4-hydroxy-5-(3-indolyl) pentanoate), an intense sweetener originally identified in root bark of the South African shrub Schlerochitin ilicifolius, was examined for its mutagenic and genotoxic potential via bacterial reverse mutation, mouse lymphoma and in vivo mouse micronucleus assays, all accomplished in the presence ...
