to define the mechanism ( s ) for the decrease of somatomedin concentrations in acute protein malnutrition , we have assessed the relationships between serum immunoreactive somatomedin-c/insulin-like growth factor-i ( sm-c/igf-i ) , serum immunoreactive gh and total ( mgcl2-treated homogenates ) as well as free ( water-treated homogenates ) liver somatogenic ( gh ) binding sites in growing rats fed a 5 % protein diet for 12 or 24 h and given an s.c .
