Here, alveolar walls are no longer visible because there is early abscessformation.

Extensive acute inflammation may lead to abscessformation, as seen here with rounded abscesses (the purulent material has drained out after sectioning to leave a cavity) in upper lobe and lower lobe.
The biodegradation pattern in vivo was similar to that in vitro. There was no abscessformation and tissue necrosis surrounding the implanted materials.
