Reduction in plasma vasopressin levels of dehydrated rats following acute stress.

摘要: The development of a sensitive radioimmunoassay for plasma arginine vasopressin (pAVP) is described. Using this assay, the levels were determined in nondehydrated and dehydrated rats after exposure to ether or acceleration stress. Plasma AVP was also following nicotine administration. Nondehydrated showed no significant changes pAVP 1, 2, 5, 15 min 1 min. Dehydrated rats, on other hand, had significantly reduced ether.
