Eight fasting students were given an infusion of porcine gastric inhibitory polypeptide (GIP) and glucose with or without atropine on two separate days. Mean serum insulin levels increased significantly and similarly on both occasions, indicating that both the glucose- and GIP-induced insulin release is unaffected by atropine. Plasma pancreatic polypeptide (PP) rose significantly during the GIP infusion on the day without atropine, suggesting a role for GIP in the intestinal phase of the PP release.
八名空腹学生在两个不同日期分别接受了猪胃抑制多肽（GIP）和葡萄糖的输注，其中一次添加了阿托品，另一次未添加。两次情况下，平均血清胰岛素水平均显著且相似地升高，表明葡萄糖和GIP诱导的胰岛素释放均不受阿托品影响。在未使用阿托品的那天，输注GIP期间血浆胰多肽（PP）显著升高，提示GIP在PP释放的肠期发挥作用。
