Outline of Final Research Achievements

In this study, we examined the roles of NO, CO, and H2S in the regulation of retinal blood flow. Our data demonstrate that NO plays an important role in the regulation of retinal blood flow. In contrast, we could not find that CO and H2S have any influences on the regulation of retinal blood flow. Further study is needed to examine the detailed mechanisms of Co and H2S in retinal blood flow using more powerful donors of CO and H2S.
