Task: Answer Verification
Input (English): Question: Does tolerance to isoflurane occur in developing Xenopus laevis tadpoles?
Answer: We provide the first description of week-long exposures of vertebrates to surgical anesthetic concentrations of isoflurane, and the first report of such exposures in developing vertebrates. Tolerance to isoflurane does not occur in developing Xenopus laevis tadpoles. Taken together with studies in other organisms, the development of tolerance to ethanol but not isoflurane suggests that mechanisms shared by these drugs probably do not account for the development of tolerance.
Output (English): no
