Insulin resistance is a prevailing cause of abnormalities in postabsorptive excursion of blood glucose and postprandial lipid profile. Excess fat deposition renders a vicious cycle of hyperglycemia and hypertriglyceridemia in the postprandial state, and both of which are contributors to atherosclerotic change of vessels especially in patients with type 2 diabetes mellitus. Several therapeutic approaches for ameliorating each of these abnormalities have been attempted, including various antidiabetic agents or new compounds targeting lipid metabolism.展开更多

Delayed postprandial hypertriglyceridemia, diabetic gastroparesis, and the possible links between them were investigated using alloxan-induced diabetic mice. After the oral administration of olive oil, delayed and exaggerated postprandial hypertriglyceridemia and diabetic gastroparesis were markedly presented in alloxan-induced diabetic mice. Domperidone shortened the time of triglycerides (TG) peak levels in diabetic mice. After intraperitoneal and intraduodenal administration of olive oil, no delay of TG peak levels occurred in diabetic mice. Simultaneously, serum post-heparin lipoprotein lipase activities significantly decreased just at the time of prolonged and elevated TG peak levels resulting from diabetic gastroparesis, and further deteriorated postprandial hypertriglyceridemia in diabetic mice. The results indicate that diabetic gastroparesis can be one of the important reasons for delayed and exaggerated postprandial hypertriglyceridemia in diabetes mellitus.展开更多
