RESULTS: In the experimental group, 20 New Zealand rabbits molding success, 2 rabbits have not obtained data because of embolization excess and anesthesia excess, the success rate of 90%. Analysis on CT images of 100 lung lobes, In 2 hours group, there are 12 lung lobes texture sparse; In 1d and 3d groups there are 22 lung lobes in ground-glass attenuation; In 7d group there are 3 lung lobes consolidation. DEPI show low perfusion in experimental group. Pathological examination revealed: The lung tissue in 2 hours group was bright red, no structural damage and alveolar exudates; In 1 day group the lung tissue was edema, congestion, hemorrhage and inflammatory cell infiltration; The lung tissue in 3 day group was deep red, the alveolar interval broaden, a large number of inflammatory cells infiltration, some lung tissue necrosis; The lung tissue in 7 day group was dark red, lung tissue necrosis, the alveolar cavity is filled with exudates. The experimental group were found three New Zealand rabbit pulmonary artery lumen with gelatin sponge.
