Hair embolism in lungs of rats after intravenous injection into caudal veins.
In case of intravenous injection into caudal veins of rats, the occasional inoculation of hair particles into the lumen of the vein cannot be avoided. These hairs either cause a local thrombophlebitis or are floated with the blood stream until they are thoughout caught by the pulmonary filters, even if they measure less than 10 mu in length. In capillaries or alveoli of lungs phagocytosis by giant cells will start after about 3 days and will be fully terminated within four weeks.
