| Outline of Final Research Achievements |
It came to be known that hydrogen sulfide was gas with a wide variety of bioactivity including vasodilator action, cytoprotective property, inhibitory effect of ischemic reperfusion injury, anti-inflammatory action. We paid attention to one of the hydrogen sulfide synthase 3-Mercaptopyruvate(3MST) using 3MST-KO and WT mouse. We found that 3MST-KO mouse was hypertension. Cardiac output was comparable between both groups, whereas peripheral vascular resistance was increased in a group of 3MST-KO. There were plasma PGI2 decrease and urinary 8-isoprostane increase in 3MST-KO, and it was suggested that an oxidative stress increase was associated with a part for a mechanism of the vascular resistance increase.
