Abstract

Vitamin E is known as a preventive agent against the development of atherosclerosis.1 On the other hand, prostacyclin (PGI2) generated by vascular endothelial cell is considered to play an important role to keep the homeostasis in vascular wall.2–4 The reduction of PGI2 production can be proposed as one of the possible causes of atherosclerosis. In our previous study, human plasma derived serum (PDS) showed a prostacyclin stimulatory activity (PSA) on cultured bovine aortic endothelial cells. Furthermore, the reduction of PSA in PDS was observed in diabetic rats and diabetic patients.5,6 Since PSA can be one of the key modulators to the development of vascular lesions, the present study was done to evaluate the effect of vitamin E on PSA when stimulated by PDS.
