Thiocyclam does not induce structural chromosome aberrations in human lymphocytes in vitro

Abstract EN

Thiocyclam (trade name Evisect) is a broad-spectrum nereistoxin analogue insecticide used widely for agricultural applications.

The aim of this investigation was to determine its genotoxic effects in the chromosome aberration (CA) test and determining of mitotic index (MI), using lymphocytes from peripheral blood samples of healthy human donors.

A negative and a positive control (MMC) were also included.

Chromosomal analyses of the metaphase plates of the samples treated with 14 different concentrations (from 0.1 to 120 lg / ml) of thiocyclam, indicating the lack effect on chromosomes.

Thus thiocyclam is not genotoxic but highly toxic on cell proliferation in human lymphocytes.
