The anastomosing occurred between the pleural superficial and the subpleural vascular networks on the capillary level or the precapillary level. The honeycomb vascular networks were also various in size and form at a low magnification. The venule connected with the pulmonary capillary networks directly at a high magnification. The single capillary networks were found in the alveolar septa. The longitudinal crests and dense round imprints of endothelial nuclei and the clear circular constrictions were found on the surface of the larger vessel in the lung parenchyma. The round imprints of endothelial nuclei also occurred on the subpleural venule and capillary.

In this experimental conditions, the VEC had not damnified obviously by perfusion with IECS in 4 hours. The pulmonary vascular resistance could decreased by POE1 and so vascular endolhelial cells would be protected. Mannitol not only increase osmotic pressure but also cleanse OFR. The addition of mannitol, POE1, glucose and osmotic pressure to IEC solution contributes to reduce the quantities of OFR.

2在本实验条件下所采用的IECS进行犬肺灌洗、离体保存4h之内肺血管内皮细胞无明显损伤，PGE；具有保护肺血管内皮细胞的作用；甘露醇具有增加渗透压和清除自由基的作用；灌洗前肺动脉内注射PGE；及增加 ECS渗透压和代谢底物、提高PH值使之略微偏碱均有助于抑制供体肺离体、低温、冷缺血保存期间OFR的产生。
