Neuroendocrine parameters during the PET studies in eight subjects studied after euglycemia and nine subjects studied after approximately 24 h of hypoglycemia*
| After EU | After HYPO | P | |
|---|---|---|---|
| Glucose (mg/dl) | 64 ± 0 | 66 ± 1 | — |
| Epinephrine (pg/ml) | 302 ± 77 | 112 ± 34 | 0.032 |
| Norepinephrine (pg/ml) | 253 ± 29 | 208 ± 31 | 0.310 |
| Glucagon (pg/ml) | 118 ± 29 | 43 ± 8 | 0.012 |
| Pancreatic polypeptide (pg/ml) | 117 ± 35 | 38 ± 9 | 0.035 |
| Growth hormone (ng/ml) | 12.1 ± 4.8 | 10.6 ± 4.1 | 0.809 |
| Cortisol (μg/dl) | 14.2 ± 2.4 | 11.7 ± 2.1 | 0.430 |
Data are means ± SE.
* To convert glucose to mmol/l multiply by 0.0551, epinephrine to pmol/l multiply by 5.485, norepinephrine to nmol/l multiply by 0.005911, glucagon to pmol/l multiply by 0.2871, pancreatic polypeptide to pmol/l multiply by 0.239, growth hormone to pmol/l multiply by 44.15, and cortisol to nmol/l multiply by 27.59. EU, euglycemia; HYPO, hypoglycemia.
