ABSTRACT
The fasting and 2 h levels of glucagon, somatostatin ( SS), and C-peptide during 75 g oral glucose tolerance test in 60 patients with type 2 diabetes and 34 normal subjects were determined. Compared with control group, the fasting levels of glucagon and SS and 2 h levels of SS after glucose loading significantly decreased,while the fasting and 2 h levels of C-peptide increased in diabetes group. The 2 h levels of these hormones were significantly higher than the fasting levels in two groups. Compared with control group, the increased folds of glucagon ( 1.40±0.48 vs 1.20±0. 30, P<0. 05 ) and SS( 2.79±2. 17 vs 1.14±0. 22, P<0. 01 ) levels after glucose loading were higher and that of C-peptide level ( 3.58 ±3. 10 vs 8. 33 ± 6. 99, P<0. 01 ) was lower in diabetes group. The levels of fasting glucagon were positively correlated with that of fasting SS in two groups( both P<0. 01 ). These results suggest that disturbance exists in hormones from α and δ cells besides the dysfunction of β cells in patients with type 2 diabetes.
