1 Time-dependent inhibition of insulin release: suppression of the arginine effect by hyperglycaemia. Arginine insulin Homo sapiens
2 Brief stimulation of the pancreas with arginine causes a refractory state which reduces the insulin response to subsequent stimulations (time-dependent inhibition). Arginine insulin Homo sapiens
3 In control subjects, a pair of arginine injections (75 mg/kg) at a 30-min interval resulted in 20% reduction of peak and integrated insulin responses to the second injection. Arginine insulin Homo sapiens
4 In Type 2 (non-insulin-dependent) diabetic patients and in obese subjects, the inhibitory effect of repeated arginine stimuli was abolished. Arginine insulin Homo sapiens
5 This induced a three- to fivefold greater insulin response to arginine. Arginine insulin Homo sapiens
6 When the arginine stimulation was repeated 30 min later, no inhibition was observed, the second insulin response being instead augmented 1.5- to 1.8-fold. Arginine insulin Homo sapiens
