SEM image of alveolar macrophages and MWNT-7 in the lung, and MWNT-7 in the pleural or abdominal fluid. a An incompletely digestion alveolar macrophage from the lung of a male rat exposed to 0.02Â mg/m3 MWNT-7. b After complete digestion of macrophages, large cocoon-like masses of fibers were observed. The spacemen was collected from the lung of a male rat exposed to 0.02Â mg/m3 MWNT-7. c MWNT-7 from the pleural fluid. The morphology of the MWNT-7 fiber is single and straight. d MWNT-7 from the abdominal fluid. The morphology of the MWNT-7 fiber is single and straight
