text: However, at anesthetic concentrations in rats, methionine synthase activity is inhibited rapidly; 50% nitrous oxide exposure decreased methionine synthase activity within 30 min, and the activity was virtually undetectable after 6 h. 48 Because nitrous oxide readily crosses the placenta, this inhibition has been recorded in both the fetus and the dam, with 60 min of nitrous oxide (50%) inhibiting methionine synthase activity to 11% and 18% in maternal and fetal livers in rats, respectively.
