Evaluation of the mutagenic potential of enflurane and isoflurane by sister chromatid exchange. 1987

R J Trudnowski, and M P Mehta, and M Rucinski

Chinese hamster lung cells were exposed to varying doses of enflurane and isoflurane mixed with oxygen, 5% carbon dioxide and nitrogen. Anesthetic concentrations varied between 0.5% and 4.0%. Controls were exposed to room air and 5% carbon dioxide. Following culturing and preparation, the number of sister chromatid exchanges were counted for each concentration. No significant difference occurred between the control and any of the drug exposed cultures. There was no correlation in the number of exchanges with the varying drug concentrations. Enflurane and isoflurane do not appear to be mutagenic under these conditions.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012854 Sister Chromatid Exchange An exchange of segments between the sister chromatids of a chromosome, either between the sister chromatids of a meiotic tetrad or between the sister chromatids of a duplicated somatic chromosome. Its frequency is increased by ultraviolet and ionizing radiation and other mutagenic agents and is particularly high in BLOOM SYNDROME.
