Outline of the department
Research in this department is directed toward pharmacological and biochemical
analyses of vascular disorders such as vasospasm, hypertension, insulin-
resistance and so on. The main research projects focus on :
1) Regulation of vascular smooth muscle contractility by endogenous substances
released from endothelial cells and nerves innervating the vascular wall. Our
attention is currently focused on regulation of synthesis of the endothelium-
derived relaxing factors including nitric oxide (NO), EDHF, etc., and on
characterization of the perivascular nerve in which NO acts as a
neurotransmitter.
2) Pre - and postjunctional mechanisms of vascular actions of chemical and
physical stimuli, and biochemical and biological measurements of inter- and
intracellular modulators involved in these actions.
3) Elucidation of the pathophysiology of vascular disorders by comparing the
vascular function, especially endothelial function, in control animals and
pathological animal models (hypertension, insulin-resistance,
hypercholesterolemia, etc.).
4) Nitrergic nerve function related to penile erection
5) Pharmacological and biochemical studies of the vascular renin-angiotensin
system and NO-cGMP pathway.
6) Mechanisms underlying re-perfusion injury in the heart
7) Heterogeneity of vascular function in relation to age, animal species,
organs and tissues.
