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...

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...
