Intra-volley interburst intervals (A) are considered to reflect the frequency of bursts of GH releasing hormone (GHRH) secretion, while intervolley interburst intervals (B) represent periods of relatively or absolutely increased somatostatin secretion. Thus, multiple GHRH bursts during an interval of decreased somatostatin secretion may give rise to volleys of GH secretion. During periods of increased somatostatin secretion, the GH response to GHRH is inhibited. 6%. ) A third approach to the analysis of pulsatile hormone release is evaluation of the regularity or pattern orderliness of hormone release over time, using the approximate entropy statistic (Pincus, 1991).
Future studies of the effects of nutrition on GH secretion should further explore these age and gender differences. Sleep In most normal subjects GH secretion is maximal at night with a close association between slow wave (stages 3 and 4) sleep and GH secretion (Takahashi, Kipnis & Daughaday, 1968). This temporal relationship has been studied by obtaining blood for measurement of GH concentrations at 30-second intervals using a continuous blood withdrawal pump and a fraction collector during concomitant electroencephalographic (EEG) sleep stage recordings in healthy young men.
1997). The mechanisms responsible for the effects of nutrition on GH secretion are poorly understood. , 1985). 5. The effect of two days of fasting on specific attributes of endogenous growth hormone (GH) secretory bursts and GH half-life as derived from deconvolution analysis of serum GH concentrations measured at 5-minute intervals for 24 hours in nine normal men. For each individual, the 24-hour endogenous GH production rate (Panel A), expressed as g per L of distribution volume (g/Lv), was estimated as the product of the total number of GH secretory bursts (Panel B) and the mean mass of GH secreted per burst (Panel C).
