Actual date on which the first participant was enrolled.

PROTOCOL OUTLINE: Antihypertensives are held, beginning 3 days before the first study day. An oral challenge is administered as follows: clonidine on day 1, yohimbine on day 2. The order of administration is reversed in alternate subjects. Timed measurements of norepinephrine, glycerol, and free fatty acids follow each challenge. Structural gene sequencing is evaluated for each participant.
