This study was designed to assess plasma glucose levels (PLG) and insulin release in totally pancreatectomized baboons when challenged with intravenous glucose administration (IVGTT). Ten animals (Papio ursinus) were used and duodenectomy was intentionally avoided. The PLG at death was 18.0 ± mmol/L, and the mean K-value within 3 days after pancreatectomy was 0.4% ± 0.2%, indicating a significant impairment of glucose disappearance from the blood when compared to the control animals (P < 0.01). Plasma insulin levels before and after stimulation with glucose were below the lowest level of insulin assay sensitivity. We conclude that in the primate, as in the dog, surgical pancreatectomy produced a reliable diabetic model, which is uniformly lethal if left untreated.
