✦ Synopsis

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 of age, 24 +/- 2 pmol/l (n = 11) at the age of 2 days and 25 +/- 2 pmol/l (n = 15) at the age of 8 days. These levels were significantly higher than in 30 healthy control adults: 11 +/- 1 pmol/l (P less than 0.01). Gavage with breast milk on the 2nd day induced a significant decrease from 21 +/- 4 to 15-2 pmol/l in 60 min (P less than 0.05). This data shows that the high plasma levels in neonates correspond to the high density of somatostatin in the neonatal pancreas and digestive tract. It also indicates that somatostatin is regulated by feeding in the neonate.

Pancreatic somatostatin cells have been studied in human neonates and adults using an immunoperoxidase technique. Their volume density in the head, isthmus, corpus and tail of the gland has been estimated by morphometry. Somatostatin cells were about 20 times more frequent in the neonate (5% of all

Big plasma somatostatin (BPS) represents an artifact of measurement. High-molecularweight globulins (CY, 8, and y) in human plasma inhibit, in a concentration-dependent manner, the binding of radiolabeled somatostatin analogs to antibody directed against somatostatin. The magnitude of inhibition var
