These results indicate that glucose and insulin may play a role in the regulation of GHRH release following a mixed meal but circulating levels of GHRH and SMS are unlikely to be relevant to the abnormal regulation of GH in IDDM.

It is concluded that in Type I diabetes the GH response to GHRH is increased, even in well regulated patients, and that the serum IGF-I level is depressed.

To examine the effects of growth hormone-releasing factor (GRF) on islet hormone release, rat pancreas was perfused. rhGRF at the concentration of 10(-7) M or more enhanced insulin secretion stimulated by 16.7 mM glucose, hpGRF slightly enhanced insulin secretion as well.

In the present study we investigated the effects of the acetylcholinesterase inhibitor pyridostigmine (PD), which is hypothesized to decrease hypothalamic somatostatin tone, alone and in association with GH-releasing hormone (GHRH) on GH secretion in 18 type 1 diabetic patients and 12 normal subjects using a randomized double blind placebo-controlled protocol.

In poorly controlled insulin-dependent diabetes mellitus (IDDM), hyperglycemia fails to inhibit the pituitary response to growth hormone-releasing factor (GRF).

In an attempt to determine if increased somatostatin (SRIF) secretion is responsible for the decreased GH secretion, we studied the effect of modulating SRIF tone on the GH response to GHRH in normal and streptozotocin-induced diabetic rats.

In the present study we investigated the effects of modulating endogenous somatostatin (SRIF) on the GH response to growth hormone-releasing hormone (GHRH) in spontaneously diabetic BB/Wor rats and nondiabetic littermates.

The dose of 4 IU of rhGH increased significantly GH levels in diabetics with preserved beta-cell function with consequent increase in IGF-I levels and attenuation of GRF induced GH response.

In addition, neither increase in IGF-I levels nor suppression of GH response to GRF on rhGH treatment was observed in CpN diabetics.

Pyridostigmine (PD), an acetylcholinesterase inhibitor, elicits GH secretion when administered alone and enhances the GH response to GHRH in normal subjects.

The strategy used was to stimulate GH secretion in 8 young (20-24 years old, body mass index (BMI) 22.8 +/- 2.8 kg/m2) and 8 elderly (68-82 years old, BMI 23.4 +/- 1.6 kg/m2) male subjects on separate occasions by means of: (i) intravenous bolus 0.5 microgram/kg D-Ala2 GHRH(1-29)-NH2 alone; (ii) 0.5 microgram/kg GHRH after pre-treatment with two oral doses of 50 mg atenolol (to inhibit somatostatin secretion); (iii) 1.25 mg oral bromocriptine alone (to increase endogenous GHRH and/or inhibit somatostatin); (iv) 50 mg oral atenolol plus 1.25 mg oral bromocriptine; and (v) 0.5 microgram/kg GHRH after pre-treatment with 1.25 mg oral bromocriptine.

Here, we demonstrate application of PICUP to cross-linking of three amyloidogenic proteins the 40- and 42-residue amyloid beta-protein variants (Abeta40 and Abeta42), and calcitonin, and a control protein, growth-hormone releasing factor (GRF).
