in this study , ethanol , an agent that modulates peroxide metabolism by catalase and selectively inhibits the activation of guanylate cyclase by h2o2 but not by nitric oxide-related activators , was employed to further investigate the role of catalase in pulmonary arterial relaxation and guanylate cyclase activation by o2 and h2o2 .
