The gaseous monoxides nitric oxide and carbon monoxide, generated within the blood vessel wall, have been identified as important cellular messengers involved in the regulation of intracellular cGMP levels, platelet aggregation and smooth muscle relaxation, The mechanism by which carbon monoxide activates soluble guanylyl cyclase is similar to that of nitric oxide, and involves binding and dislocation of its heme-iron to induce a conformational change and activation of the catalytic site of guanylyl cyclase.

一氧化氮是体内最重要的气体信使分子，不仅是维持血管正常舒缩功能的重要介质，而且还有抑制单核细胞及血小板与内皮的粘附、聚集、抑制血管平滑肌细胞的增殖等作用。近年研究表明，内源性一氧化碳是体内另一个重要的气体信使分子，它是由血红素氧合酶氧化分解血红素产生的，具有与一氧化氮相似的生理功能。

The results show that DCRP is indeed a excellent flame retardant. The material can reach the UL-94-V-0 level through choice different synergist. Many alternative synergists to antimony oxide are available for use. Zine and iron compounds are often used in place of the standard antimony oxide because of their lower cost and special properties. Additionally, synergist mixtures are also useful in obtaining specific properties.
