“…In leprechaunism the only report of HGH assay is an isolated measurement reported by Dekaban (1965) which is at the upper level of the normal fasting range (1-10 tlu/ml). The total lack of subcutaneous fat in Russell's diencephalic syndrome may be partly attributable to increased production of HGH, but the lipid mobilizing fraction (LM) isolated by Zarafonetis, Seifter, Baeder, and Kalas (1959) from the pituitary and the fat mobilizing polypeptide (FMS) isolated from urine by Chalmers, Pawan, and Kekwick (1960) may also play their part. These last two substances may be quite unrelated to HGH but Pawan (1971) suggests that FMS may in fact prove to be a degradation product of HGH.…”
