摘要

本研究旨在了解metavanadate (SMV)的降糖机制,结果表明口服SMV后肝脏葡萄糖激酶和肌肉己糖激酶活性迅速升高,血糖水平与这两种酶的活性密切相关,而与胰岛素水平无关;这表明SMV可以在不刺激胰岛素分泌的情况下改善糖尿病小鼠葡萄糖磷酸化的改变。这可能是SMV降血糖作用的机制之一。

Effects of vanadate on the activities of mice glucokinase and hexokinase.

This study aimed at acquiring knowledge on the hypoglycemic mechanisms of sodium metavanadate (SMV) showed that the liver glucokinase and muscle hexokinase activities increased rapidly after oral SMV was given, and that the blood glucose level was correlated closely with the activities of the two enzymes but not with the insulin level; which indicated that SMV could improve the altered glucose phosphorylation in diabetic mice independently of stimulating insulin secretion. This was probably one of the mechanisms of hypoglycemic effects of SMV.
