摘要(Abstract)：

目的观察海水淹溺后家兔肺组织光镜下变化,并探讨三七总皂苷干预对海水淹溺后家兔肺泡巨噬细胞内TNF-αmRNA表达的影响。方法采用气管切开插入塑料导管、向气管内灌海水4mL/kg,双肺自主通气的方法模拟海水淹溺造成急性肺损伤模型,随机分为对照组、海水淹溺组、三七总皂苷治疗组。于淹溺后进行血气分析,采集支气管肺泡灌洗液,分离和培养肺泡巨噬细胞,并采集肺组织进行病理学分析,逆转录-聚合酶链反应(RT-PCR)检测肺泡巨噬细胞中TNF-αmRNA的表达。结果光镜下,海水淹溺兔肺组织炎症细胞大量浸润,经三七总皂苷治疗后肺组织损伤程度减轻。RT-PCR分析示淹溺后TNF-αmRNA表达显著增高,90min后达最高峰,而三七总皂苷可使之降低。结论海水淹溺急性肺损伤可能与肺泡巨噬细胞内TNF-αmRNA高表达有关。三七总皂苷可降低TNF-αmRNA的高表达,减轻肺损伤程度。
