Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract A comparative study of the genotoxic effects of methylmethanesulfonate (MMS) and epichlorohydrin (ECH) was performed using bacterial E. coli biosensors and the comet assay method in mice. ECH was shown to induce weaker SOS response and expression of the alkA gene in bacterial cells compared to MMS. In vivo experiments on mice using the comet assay method showed DNA-damaging activity of ECH in cells of the liver, kidneys, and lungs after 3 h of exposure, same as of MMS. The levels of DNA damage caused by ECH in these organs after exposure for 3 h were lower than for MMS. The genotoxic effect of ECH after 18 h of exposure was statistically significant only in a dose of 20 mg/kg in kidney cells.
