摘要: Plasma ACTH, arginine vasopressin (AVP), and catecholamines were measured at 5-min intervals in the pituitary venous effluent of unanesthetized horse. Pulses ACTH AVP found to be surprisingly brief (usually less than 10–min duration) frequent (averaging between 15–25 min). A highly significant relationship changes concentration these two hormones was demonstrated (P > 0.0002) both rest after a mild hypoglycemic stimulus. Although there also correlation 0.005) simultaneous plasma values pulse amplitude ratio showed considerable variation. rise cortisol appeared have greater suppressive effect on pulses. The gradient hormonal jugular times over 50–fold for 500–fold AVP. epinephrine, norepinephrine, dopamine. ...
