Proliferation of the vascular endothelium of the parathyroid glands of dogs exposed to ozone inhalation was studied. Direct observation of mitoses in the endothelial cells were made. Focal hemorrhages in the form of the presence of erythrocytes, clotting, and fibrin deposition in the extravascular spaces were seen. Ultrastructural analysis of transverse section of blood vessels showed intravascular platelet aggregation. Lymphoid cells were observed in the lumen of the blood vessels as well as in the perivascular areas as infiltrates. The possibility is discussed that present vascular reactions signify the morphologic equivalent of an immunologic response.
