Samples of proximal and distal tubular fuid were collected from control rats and from adrenalectomized animals maintained on 0.90/0 NaC1 solution. Plasma and tubular fluid were analyzed for Na 22 afber adequate isotope equilibration and for Na and K by microflamephotometry. Similar analyses were per
Plasma somatostatin concentration was measured by radioimmunoassay in 26 preterm neonates (mean gestational age 34 weeks). None were seriously ill and they were all fed with breast-milk 12 h after birth. In a longitudinal study the concentrations were (mean +/- SEM): 21 +/- 2 pmol/l (n = 8) at 2-8 h
