Lung Matrix Metalloproteinase Activation following Partial Hepatic Ischemia/Reperfusion Injury in Rats
Figure 6
Representative sections of lung tissue from sham-operated animals (a, b, and c) and from animals submitted to hepatic ischemia/reperfusion (I/R) (d, e, and f). Hematoxylin and eosin staining. The sections from sham animals show the typical morphology of bronchi (B), blood vessels, and alveoli (alv) with associated capillaries; alveolar capillaries are recognizable in high magnification (c), by erythrocytes in the lumen. In the lung tissues of animals submitted to hepatic I/R alveoli appear to be dilated. (d, e) Dilated lymph vessels (L) surrounding arteries (A) and an abundant number of inflammatory cells (arrowheads) in the lumen and stroma of blood vessels (f).
