Abstract:
Intercellular junctions of the alveolar epithelium and the capillary endothelium in lungs from 4 sheep with oxygen toxicity and 3 control sheep were studied with freeze-fracture techniques. Electron microscopic examination revealed no significant difference existing between the number of strands, both in the epithelium and in the endothelium. in the oxygen toxicity group and in the control group. However, the incidences of the discontinuity, irregularity and free-ended strands were higher in the oxygen toxicity group than in the control group. The differences in most of these features between the two groups were highly significant(P
