Atypical cilia in ciliated cysts of the parathyroid glands of dogs exposed to ozone.
This report deals with the occurrence of atypical cilia in ciliated cysts of parathyroid glands in dogs after exposure to ozone inhalation at 0.75 ppm close level for 48 h. Electron microscopic examination revealed cytoplasmic blebs with none, one, two ore more axial microtubule complexes (compound) surrounded by a single membrane and containing little or excessive matrix. Also seen where helicoidal cilia. The present anomalous behaviour of the cilia in the prevalent ciliated cysts in ozone treated dogs is consistent with the previously described effects of ozone inhalation on the parathyroid glands.
