(-)-Epicatechin (1), a naturally occurring flavonoid compound was found to have reversed the diabetogenic action of alloxan in albino rats (2). (-)-Epicatechin administration in doses of 30 mg/kg (i.p.) twice daily for 4-5 days in alloxan induced (150 mg/kg, i.p.) diabetic albino rats (either sex), has brought down the high blood sugar levels to normal values. Concurrent histological studies of the pancreas of these animals showed regeneration of the beta-cell population of the islets which were earlier necrosed by alloxan. Immunoreactive insulin (IRI) studies showed that the regenerated beta-cells of the islets of pancreas are functional in nature.
(-)-表儿茶素(1)是一种天然存在的黄酮类化合物,已发现它能逆转四氧嘧啶对白化病大鼠的致糖尿病作用(2)。在四氧嘧啶诱导(腹腔注射150mg/kg)的糖尿病白化病大鼠(雌雄不限)中,每天两次腹腔注射剂量为30mg/kg的(-)-表儿茶素,持续4-5天,可使高血糖水平降至正常。对这些动物胰腺的同步组织学研究表明,胰岛的β细胞群发生了再生,这些细胞先前已被四氧嘧啶坏死。免疫反应性胰岛素(IRI)研究表明,胰腺胰岛中再生的β细胞具有功能。
