    • Topical exposure of nitric oxide gas to wounds such as chronic non-healing wounds may be beneficial in promoting healing of the wound and in preparing the wound bed for further treatment and recovery. Nitric oxide gas may be used, for example, to reduce the microbial infection and burden on these wounds, manage exudate secretion by reducing inflammation, upregulate expression of endogenous collagenase to locally debride the wound, and regulate the formation of collagen. High concentration of nitric oxide ranging from about 160 to 400 ppm may be used without inducing toxicity in the healthy cells around a wound site. Additionally, exposure to the high concentration for a first treatment period reduces the microbial burden and inflammation at the wound site and increase collagenase expression to debride necrotic tissue at the wound site. After a first treatment period with high concentration of nitric oxide, a second treatment period at a lower concentration of nitric oxide preferably ranging from about 5-20 ppm may to provided to restore the balance of nitric oxide and induce collagen expression to aid in the closure of the wound.
    • 一氧化氮气体局部暴露于伤口如慢性非愈合伤口可能有益于促进伤口愈合和制备伤口床进一步治疗和恢复。 例如,可以使用一氧化氮气体来减少这些伤口的微生物感染和负担,通过减少炎症,上调内源性胶原酶的表达来局部清创伤口并调节胶原的形成来控制渗出物分泌。 可以使用约160至400ppm范围内的高浓度一氧化氮,而不会在伤口部位周围的健康细胞中引起毒性。 此外,在第一次治疗期间暴露于高浓度可减少伤口部位的微生物负担和炎症,并增加胶原酶表达以清除伤口部位的坏死组织。 在具有高浓度一氧化氮的第一次治疗期后,可提供较低浓度的一氧化氮优选约5-20ppm的第二治疗期以恢复一氧化氮的平衡并诱导胶原表达以帮助闭合 的伤口。
