THE INFLUENCE OF AMINO ACIDS AND SOMATOSTATIN ON PROLACTIN AND GROWTH HORMONE RELEASE IN MAN
By P. Bratusch-Marrain and W. Waldh\l=a"\usl
ABSTRACT The effect of
an
iv load of individual amino acids
histidine, leucine, phenylalanine, and valine)
(alanine, arginine, prolactin (Prl) and healthy adult males
on serum
growth hormone (GH) concentrations was studied in (n=5). A rise in both, Prl and GH with a maximal increment of 15.9\m=+-\6.7 (se) ng/ml, and 12.4\m=+-\4.9 ng/ml above basal levels, respectively, (P< 0.05) was observed after iv arginine. Following iv phenylalanine the mean peak level of Prl rose from 9.9 \m=+-\3.5 to 29.9 \m=+-\7.3 ng/ml (P
