Abstract

  • 1.

    1. A urinary polypeptide (FI) from the urine of lipoatrophic diabetics and a similar peptide (BPI) from bovine adenohypophysis induced significant fasting hypoglycemia and increased glucose tolerance in the mouse.

  • 2.

    2. The effects of FI and BPI on blood sugar levels were absent in mice pretreated with alloxan and D-mannoheptulose.

  • 3.

    3. Plasma immunoinsulin was significantly increased after FI and BPI administration and significantly decreased in mice pretreated with D-mannoheptulose.

  • 4.

    4. It was concluded that FI and BPI induction of fasting hypoglycemia and enhanced glucose tolerance is mediated by endogenous insulin release.

垂体和尿肽诱导小鼠空腹低血糖和高胰岛素血症
1.1. 从脂肪萎缩性糖尿病患者的尿液中提取的尿多肽(FI)和从牛腺垂体提取的类似肽(BPI)在小鼠中诱导了显著的空腹低血糖和葡萄糖耐量的增加。在四氧嘧啶和d -甘露庚糖预处理的小鼠中,FI和BPI对血糖水平的影响不存在。给予FI和BPI后,小鼠血浆免疫胰岛素显著升高,给予d -甘露庚糖预处理小鼠血浆免疫胰岛素显著降低。综上所述,FI和BPI诱导空腹低血糖和糖耐量增强是由内源性胰岛素释放介导的。
