肺泡表面张力

肺容积和肺泡表面张力对肺血管阻力的影响

Effects of Lung Volume and Alveolar Surface Tension on Pulmonary Vascular Resistance

表面活性物质B（surfactantproteinB，SP-B）是肺泡表面活性物质的基本成分，起着减小肺泡表面张力的作用，对于出生后呼吸适应是必需的。

Surfactant protein B ( SP-B ) is an essential component of surfactant . It plays a role of diminishing alveolar surface tension , and is required for postnatal respiratory adaptation .

肺表面活性物质由磷脂和与其特异性结合的蛋白即肺表面活性物质相关蛋白（SPs）组成，前者能有效降低肺泡表面张力，而后者是磷脂发挥作用必不可少的部分。

PS is composed of phospholipid and the specific combined proteins ( surfactant associated proteins , SPs ) . Phospholipid can reduce the surface tension of alveolus , SPs are the necessary part in this process .

结果经NAC治疗后spamRNA表达增强，静态肺顺应性增加，肺泡灌洗液表面张力特征恢复正常，Ⅱ型细胞板层体恢复至正常形态。

Results After the application of NAC , there exhibited an increase in SPA mRNA expression and static pulmonary compliance , and the restoration of the BAL surface tension to normal .

方法采用烟雾吸入性损伤的大鼠模型，观察NAC治疗后spamRNA表达情况，并检测静态肺顺应性、肺泡灌洗液表面张力及Ⅱ型细胞板层体形态。

Methods Wistar rats inflicted with smoke inhalation injury were employed as the model . The expression of SPA mRNA , the static pulmonary compliance , the surface tension of the alveolar lavage and the morphology of lamellae bodies ( LB ) of type ⅱ alveolar cells were examined .
