检测幽门螺杆菌（HelicobacterPylori,Hp）感染胃炎患者鲁窦粘膜体外培养上消液中肿瘤坏死因子（TumorNecrosisFactor－α，TNF－α）和血小板源生长因子（Platelet－derivedGrowthFactor，PDGF）水平。结果表明，Hp阳性胃炎患者留其粘膜TNF－α含量和PDGF活性均明显高于Hp阴性患者和正常对照组，合并活动性胃炎患者胃窦TNF－α含量和PDGF活性也明显高于非活动性胃炎。 To detect the levels of Tumor Necrosis Factor-α (TNF-α) and Platelet-derived Growth Factor (PDGF) in the culture fluid of the patients with Helicobacter pylori (Hp) infection in the gastritis. The results showed that the contents of TNF-α and PDGF in mucosa of patients with Hp-positive gastritis were significantly higher than those in Hp-negative patients and normal controls. TNF-α and PDGF activity in gastric antrum in patients with active gastritis were also significantly higher than those in inactive patients gastritis.
