Clonidine 0-9 somatoliberin Ovis aries 185-189 7905408-9 1994 These data suggest that clonidine acts centrally to stimulate hypophysial GH secretion in the sheep and that this effect is mediated through changes in GHRH, but not SRIH, release into hypophysial portal blood. Clonidine 24-33 somatoliberin Ovis aries 152-156 22517235-4 2012 Using a transnasal surgery technique in awake sheep that allowed accessing hypothalamopituitary portal vessels, our laboratory previously reported that the injection of clonidine in sheep induced a significant, immediate and short-lasting increase in peripheral GH and portal GH-releasing hormone (GHRH) levels. Clonidine 169-178 somatoliberin Ovis aries 276-296 22517235-4 2012 Using a transnasal surgery technique in awake sheep that allowed accessing hypothalamopituitary portal vessels, our laboratory previously reported that the injection of clonidine in sheep induced a significant, immediate and short-lasting increase in peripheral GH and portal GH-releasing hormone (GHRH) levels. Clonidine 169-178 somatoliberin Ovis aries 298-302 22517235-5 2012 In this study, we show that the clonidine-induced peripheral GH and portal GHRH increase in sheep appears to be mediated by the tachykinin NK2 receptor.
