幽门螺杆菌（Ｈｐ）感染可引起胃粘膜大量炎症细胞浸润、肿瘤坏死因子α（ＴＮＦ－α）等细胞因子产生增多和一氧化氮合酶（ＮＯＳ）活性增强。一氧化氮（ＮＯ）具有细胞保护和毒性双重作用，为探讨Ｈｐ感染时胃粘膜炎症程度、ＴＮＦ－α含量和ＮＯＳ活性的关系，对２２例...
Helicobacter pylori (Hp) infection can cause a large number of gastric mucosal inflammatory cell infiltration, tumor necrosis factor α (TNF-α) and other cytokines increased and nitric oxide synthase (NOS) activity increased. Nitric oxide (NO) has the dual role of cell protection and toxicity, in order to explore the degree of gastric mucosal inflammation Hp infection, TNF-α content and NOS activity in 22 cases of ...
