Using a specific antagonist of the pressor activity of vasopressin, we found no significant effect on heart rate, mean arterial pressure, cardiac output (thermodilution), and peripheral vascular resistance in the control animals and in the rats with aorto-caval fistula. Captopril resulted in a ...
Vasopressin tends to decrease heart rate and cardiac output. The pressor effect is proportional to the infusion rate of exogenous vasopressin. The pressor effect reaches its peak within 15 minutes. After stopping the infusion the pressor effect fades within 20 minutes. There is no evidence for ...
Heart rate (=0.025) and oxygen requirement (=0.021) also declined after initiation. Serum sodium declined initially and recovered by 72h (=0.017).Although there is limited experience with vasopressin use in neonatal HOCM, our case series suggests it may be beneficial for improving systemic ...
Similar quantities of intravenous fluid were given to all groups, and total fluid balance, serum lactate levels, and heart rate were similar in all groups (eTables 4-7 in Supplement 2). Serum creatinine levels were lower and urine output slightly higher over the first 7 days in the vasopres...
The vasodepressor action of prostacyclin (PGI2) and its effect on plasma angiotensin II and vasopressin in unanaesthetized normotensive and hypertensive rats. The action of prostacyclin (PGI2) on arterial pressure, heart rate, plasma concentration of angiotensin II and vasopressin was studied in groups...
The heart: a target organ for estradiol Autoradiographic studies of rat heart reveal that tritiated estradiol concentrates in cell nuclei of the myocardium of the atria and auricles, similar to t... W Stumpf,M Sar,G Aumuller - 《Science》 被引量: 423发表: 1977年 Canine vascular tissues ar...
In addition, angiotensin II has been shown to participate in baroreflex regulation of blood pressure, heart rate, cardiac output and vasopressin and ACTH secretion. A second aim of this proposal is to determine, using specific receptor antagonists, whether endogenous angiotensin II affects baroreflex...
Methods Eight healthy men were instructed to performed isotonic and resistance exercises, respectively, with the same target heart rate and the same exercise duration, in which both exercises-induced changes of plasma renin activity (PRA), aldosterone (ALDO) and antidiuretic hormone (ADH) were observ...
Effects of Microinjection of Vasopressin into Medial Amygdaloid Nucleus on Blood Pressure and Heart Rate in Spontaneously Hypertensive Rate Our studies were done to determine (1) the cardiovascular effects of electrical stimulating and microinjection of vasopressin (AVP) into the medial amygdal... L ...
Coincident with the fall in PAP were similar reductions in cardiac output and heart rate. Similarly, bolus administration of AVP reduced PAP, and this effect was augmented during hypoxia. Another series of experiments examined the effect of endogenous AVP released by arterial hypoxemia on pulmonary ...
