... peptide level (five patients) significantly increased from 7.6 k 4.6 pg/ml to 34.6 f 21.7 pg/ml ( P < 0.02) during the arrhythmia. There was no significant change in the plasma arginine- vasopressin level and a non-significant reduction in plasma renin activity. 4. This study has shown that induced...

...Felix Vargas; Maria J. Baz; Juan de D. Luna; Jesus Andrade; Esteban Jodar; Jose M. Haro 1. Urinary excretion of digoxin-like immunoreactive factor and arginine-vasopressin and other parameters related to salt and water metabolism were studied in hyper- and hypo-thyroid rats after different tests. 2...

...B. Ricciardelli; M. Volpe; B. Trimarco; M. Chiariello; F. Rengo; Mario Condorelli 1. The reflex control of arginine-vasopressin release was studied in 12 essential established hypertensive patients and in 12 age-matched normal subjects by comparing the effects of head-up tilt and a variable...

...W. Rascher; R. E. Lang; M. Taubitz; H. Meffle; TH. Unger; D. Ganten; F. Gross 1. The role of arginine-vasopressin (AVP) in the maintenance of high blood pressure in rats with deoxycorticosterone acetate (DOCA) hypertension was investigated. 2. Plasma concentrations of AVP were significantly...

...T. H. Thomas; S. G. Ball; J. K. Wales; M. R. Lee 1. Five normal subjects were studied before and during treatment with carbamazepine. 2. Plasma sodium, plasma and urine arginine-vasopressin and urine osmolality were measured during a day of water deprivation, before and during drug treatment. 3...

...T. H. Thomas; M. R. Lee 1. Rabbit antisera against arginine-vasopressin (AVP) were evaluated for sensitivity and specificity in a radioimmunoassay based on the extraction of AVP from plasma and urine on to Florisil. 2. Comparison of the immunoreactivity of AVP with analogues showed that one...

...A. M. Khokhar; J. D. H. Slater 1. The rate of renal excretion of arginine-vasopressin was determined during unrestricted fluid intake for 24 h and in response to fluid deprivation for 18 h in nine young men with very mild essential hypertension and compared with that in sixteen normotensive men...
