近10年病理生理学研究已证明,由血管内皮释放的一氧化氮是内环境稳定调节剂,具有强大的血管舒张作用和抗凝血酶原作用,能防止炎症灶和缺血灶白细胞和血小板活化引起的不良后果。一氧化氮有细胞保护作用,可防止内皮损害和剥脱。牙周病时局部聚集着大量活化的白细胞,本文研究中性粒细胞(PML)灭活一氧化氮的作用。 检查慢性广泛性牙周炎患者22例,年龄20～50 Nearly 10 years of pathophysiology studies have shown that the release of nitric oxide from the vascular endothelium is a stable regulator of the environment with a strong vasodilator effect and anti-prothrombin to prevent inflammatory lesions and ischemic lesions of white blood cells and platelet activation Caused by the adverse consequences. Nitric oxide has cytoprotective effects that prevent endothelial damage and exfoliation. Periodontal disease local accumulation of a large number of activated leukocytes, the paper studies the neutrophil (PML) inactivation of nitric oxide. Twenty-two patients with chronic periodontitis were examined, ranging in age from 20 to 50 years
