title: Toxicity and teratogenicity of inhaled anesthetics in Drosophila melanogaster.
abstract: The toxic and teratogenic effects of inhaled anesthetics were assessed in an in vivo assay using the fruit fly Drosophila melanogaster. Eggs were exposed during development (metamorphosis) to enflurane, isoflurane or halothane at a vapor concentration of 0.1 or 0.2% (v/v), to fluroxene at 0.025 or 0.05% (v/v), or to nitrous oxide at 20 or 40% (v/v). Flies produced in each group were counted and were examined for morphological abnormalities within one day of hatching. All the anesthetics except nitrous oxide produced a dose-dependent increase in the duration of metamorphosis and a decrease in the number of flies. Despite these effects on development, no morphological abnormalities were observed in any fly.
