Glucagon (1 mg) and glucose (60 ml of 50% solution) were infused over 60 min to three normal and one obese subjects and two insulinoma patients. Plasma C-peptide immunoreactivity (CPR) and immunoreactive insulin (IRI) increased during the infusion. Half time of CPR after cessation of the infusion was 20.1 +/- 4.0 min, and that of IRI 9.8 +/- 1.3 min, respectively. This difference partly explains the higher molar concentration in plasma of CPR than IRI.
向3名正常受试者、1名肥胖受试者和2名胰岛素瘤患者在60分钟内输注胰高血糖素（1毫克）和葡萄糖（60毫升50%溶液）。输注期间血浆C肽免疫反应性（CPR）和免疫反应性胰岛素（IRI）升高。输注停止后CPR的半衰期分别为20.1±4.0分钟，IRI的半衰期为9.8±1.3分钟。这种差异部分解释了血浆中CPR的摩尔浓度高于IRI。
