  • Title: A comparison of some activities of arginine vasopressin and lysine vasopressin on kidney function in conscious dogs.
    Author: ALI MN.
    Journal: Br J Pharmacol Chemother; 1958 Jun; 13(2):131-7. PubMed ID: 13536276.
    Abstract:
    Comparison was made on conscious trained dogs of the effect of highly purified arginine vasopressin and lysine vasopressin on the rate of urine flow, the excretion rate of Na and K and the renal clearances of creatinine and diodone, and of the actions of the vasopressins when administered together with oxytocin. The vasopressins were used in doses causing a maximal antidiuresis.The results showed, first, that the antidiuretic potency of arginine vasopressin was greater than that of lysine vasopressin and that its action lasted longer; second, that during water diuresis arginine vasopressin increased only Na excretion while lysine vasopressin increased both Na and K excretion; third, that arginine vasopressin had a potency about 5 to 6 times that of lysine vasopressin in antagonizing the augmentor effect of oxytocin on glomerular filtration rate and renal plasma flow.
