Arterial plasma insulin, glucagon, and cortisol concentrations and hepatic blood flow during the preclamp and clamp periods
| Parameter and group | Before the clamp (330–360 min) | Clamp period (360–600 min) |
|---|---|---|
| Arterial insulin (µU/mL) | ||
| SAL | 5 ± 1 | 19 ± 2 |
| GLC | 6 ± 1 | 23 ± 2 |
| Arterial glucagon (ng/L) | ||
| SAL | 30 ± 4 | 31 ± 5 |
| GLC | 40 ± 4 | 39 ± 4 |
| Arterial cortisol (µg/dL) | ||
| SAL | 2.7 ± 0.6 | 3.4 ± 0.8 |
| GLC | 1.7 ± 0.5 | 2.8 ± 0.7 |
| Total hepatic blood flow (mL ⋅ kg−1 ⋅ min−1) | ||
| SAL | 34 ± 1 | 31 ± 2 |
| GLC | 30 ± 3 | 30 ± 4 |
Data are mean ± SEM (n = 6 dogs/group) for all time points during the indicated period. There were no significant differences between groups.
