Variance of ACE and AT1 receptor gene does not influence the risk of neonatal acute renal failure
High neonatal activity of the renin-angiotensin system (RAS) is crucial for the maintenance of glomerular filtration of the newborn. The aim of the present study was to investigate whether genetic polymorphis...

Monitoring cardiovascular changes during hemodialysis in children
Hemodialysis (HD) causes rapid volume shifts and circulatory changes. In chronic renal failure (CRF) Na+/K+ATP-ase is depressed, whereas endogenous digoxin-like factor (EDLF) is elevated. Our aim was to character...

Normal kidney function and elevated natriuresis in young men born with low birth weight
The aim of our study was to characterize renal function and its relationship to blood pressure in healthy young Caucasian men born with a birth weight under 2,500 g (LBW). Urinary protein patterns, N-acetylglucos...

Renal excretion of endothelin in children
Endothelin (ET) is a peptide with profound vasoconstrictive potential. First isolated from porcine endothelial cell supernatant, it is produced also by smooth muscle, epithelial and circulating cells. Besides...

Endothelin excretion during ketoacidosis does not correlate with tubular dysfunction
Urinary excretion of endothelin was measured by radioimmunoassay in children with diabetes mellitus during severe ketoacidosis and 12 days later when blood pH and blood glucose concentrations were normal. Meta...

Atrial natriuretic peptide and sodium homeostasis in chronic renal failure
In order to evaluate the possible role of vasoactive hormones in the mechanism of exaggerated sodium loss due to reduced renal mass we measured plasma concentration of atrial natriuretic peptide (ANP), aldoste...

Effect of low-dose dopamine infusion on urinary prostaglandin E2 excretion in sick, preterm infants
In pharmacological doses dopamine (DA) will interact with several endocrine systems and both inhibit (prolactin, thyrotropin) and enhance (renin, angiotensin) hormonal release. In this study we have examined w...

REGULATION OF PLASMA ATRIAL NATRIURETIC PEPTIDE IN CHILDHOOD
A trial natriuretic peptide (ANP) is released from cardiac atria into circulation and induces diuresis and natriuresis. We studied plasma ANP in children using a sensitive radioimmunoassay.

CARDIOVASCULAR AND RENAL RESPONSE TO DOPAMINE IN PRETERM NEONATES WITH CIRCULATORY FAILURE
49 preterm infants (BW: 1700±385 g; GA: 31,8±1,8 w; PA: 9,8±6,8 h) were treated with dopamine (D) because of peripheral circulatory disturbance. A dosis of 2 μg/kg/min D was administered in mild circulatory fa...

The effect of dopamine administration on the activity of the renin-angiotensin-aldosterone system in sick preterm infants
Nine premature infants with birth weight of 1150 to 2500 g and gestational age of 28 to 35 weeks were given dopamine in a dose of 2–4 μg/kg/min to treat cardiopulmonary distress.

Cardiovascular response to dopamine in hypotensive preterm neonates with severe hyaline membrane disease
The effect of low dose (2, 4, and 8 μg/kg per min) dopamine infusion on blood pressure, heart rate and renal function was studied in 18 hypotensive, preterm infants with severe hyaline membrane disease (HMD). ...
