Research Topics

1. Study on the mechanisms by which omega-3 polyunsaturated fatty acids lower blood pressure.

2. Study on the effects of omega-3 polyunsaturated fatty acids on prostanoid receptors.

3. Study on agonists and antagonists of smooth muscle contraction.

DHA and EPA, the major omega-3 polyunsaturated fatty acids (PUFAs), contained in fish oil, which show antihypertensive effects, reduction of platelet aggregation and of plasma triglycerides. Our main research is focused on the effects of these PUFAs on prostanoid receptors regulating the vascular smooth muscle tone in hypertension. We have a good command of in vivo and in vitro techniques which allow us to study how these PUFAs exerts actions on the cardiovascular systems. The objectives of our research are to clarify the mechanism of hypertension and prove the effects of PUFAs contained in fish oil.
