TABLE V. EFFECT OF VARIOUS MONOAMINE OXIDASE INHIBITORS ON THE ACTIONS OF 5,7-DHT.
Values represent the mean ± S.E.M. of 5–14 determinations. Animals were pretreated with monoamine oxidase inhibitors 30 min before receiving 200 µg of 5,7-DHT intracisternally and were killed 21 days after treatment.
