[Release of antidiuretic hormone (ADH) under the influence of gastric distention in the rabbit. Demonstration by radioimmunoassay].
In this investigation, are studied in rabbits, the effects of gastric distention upon plasma concentration of vasopressin; the arginine-vasopressine is determined by a very sensitive radio-immunologic method. Increases of intragastric ballonet pressure up to 10-20 cmH2O induce significant rise in plasma vasopressin concentrations averaging 21 +/- 3,7 muU/ml (base line 6,25 +/- 2,3 muU/ml). Increase of vasopressin is associated with significantly lowered diuresis. Intravenous injections of nicotine induce similar decrease in urine flow and increase of plasma AVP concentrations up to 12,01 +/- 1,7 muU/ml.
