Sex differences in anaesthetic toxicity: fluroxene and trifluoroethanol in mice.
نویسندگان
چکیده
A sex difference in postanaesthetic mortality after fluroxene anaesthesia was found in Swiss Webster mice. More males succumbed than females. This toxicity was biotransformation-dependent and could be reversed by pretreatment with "opposite" sex hormones. The toxicity of the fluroxene metabolite trifluoroethanol also was more marked in male mice, but was only partially influenced by microsomal enzyme inhibitors or stimulators, or by sex hormones.

Metabolism and toxicity of 2,2,2-trifluoroethyl vinyl ether.
A review on metabolism and toxicity of the fluorinated anesthetic agent, fluroxene, is presented. Fluroxene anesthesia is nontoxic to man but fatal to many experimental animals. The fluroxene molecule (2,2,2-trifluroethyl vinyl ether) is composed of two moieties; both are toxic as a result of their metabolism: the vinyl moiety destroys heme of cytochrome P-450 while being metabolized to the fin...
متن کاملSister chromatid exchanges in human lymphocytes after anaesthesia with fluroxene.
The potential mutagenicity of fluroxene was investigated by the sister chromatid exchange (SCE) test using lymphocytes in peripheral blood from patients before and after anaesthesia. Twenty-five female patients, aged 21 -77 yr (median 36.5yr) were anaesthetized for gynaecological operations with fluroxene in nitrous oxide for 60-220 nun (median 110 min). The number of SCE per cell was the same ...
