The relativepotency of national TSH standard to 2~(nd) international reference preparation was 0.942. However, there was some difference between each immunoassay methods.
To determine the motor block minimum local analgesic concentrations (EC50) of levobupivacaine and ropivacaine, and compare the relativepotency of these drugs used in epidural space.
