S. Lal et al., EFFECT OF SLEEP-DEPRIVATION ON THE GROWTH-HORMONE RESPONSE TO THE ALPHA-2-ADRENERGIC RECEPTOR AGONIST, CLONIDINE, IN NORMAL SUBJECTS, Journal of neural transmission, 104(2-3), 1997, pp. 291-298
One night's sleep deprivation (SD) increased the growth hormone (GH) r
esponse to clonidine (2 ug/kg iv) in II normal men (p < 0.005). This f
inding may indicate that SD enhances alpha-2 adrenergic receptor funct
ion or that the GH response to GH releasing factor is increased by SD.
