| 摘 要： | 目的探讨乙酰唑胺对大鼠高原肺水肿的预防作用及其机制。方法雄性Wistar大鼠随机分为3组,分别为对照组、安慰剂组、乙酰唑胺组。建立大鼠高原肺水肿模型,观察乙酰唑胺100mg/（kg·d）干预5d后大鼠的肺湿干比（W/D）,肺泡灌洗液（BALF）蛋白浓度,肺损伤病理积分,血清和肺组织中一氧化氮（NO）含量、一氧化氮合酶（NOS）活力的变化。结果安慰剂组大鼠肺W/D、BALF蛋白浓度、肺损伤病理积分明显高于对照组（P〈0.05）,乙酰唑胺组肺湿干比、BALF蛋白浓度、肺水肿及出血积分较安慰剂组显著降低（P〈0.05）。安慰剂组大鼠血清及肺组织匀浆中NO含量及NOS活力显著低于对照组,乙酰唑胺组大鼠血清及肺组织匀浆中NO含量及NOS活力显著高于安慰剂组（P〈0.05）。结论乙酰唑胺给药5d可有效预防大鼠高原肺水肿,其作用机制可能与上调血清及肺组织内NO含量及NOS活力有关。 |

| Abstract: | Objective To study the preventive effect of acetazolamide(AZ) on high-altitude pulmonary edema(HAPE) in rats and its possible mechanism.Methods Male Wistar rats were randomly divided into control group,AZ group,and placebo group.A rat HAPE model was established.Five days after the rats were interfered with AZ at the dose of 100mg/(kg.d),the wet/ dry(W/D) ratio,protein concentration in bronchoalveolar lavage fluid(BALF),pulmonary edema and hemorrhage score,nitric oxide(NO) level and NO synthase(NOS) activity... |
