Using low osmolality, nonionized contrast medium Io- pamiro-300, Bracco mixed with the mucus prepared from the seed flax (Linum usitatissimum, L), a dacryocistor- hinography was performed experimentally on 8 healthy mongrel dogs. Assessing the occurrence of local and general complications was the aim of the investigation. On the basis of a radiographic examination it has been shown that the mixture of the contrast medium and seed flax mucus appeared to be a very useful compound for dacryo- cistorhinography, especially for the evaluation of nasolacrimal duct system course and its patency. Clinical observations and a histological examination proved that this compound of the contrast medium was well tolerated by the mucous membrane of the nasolacrimal system and the external eye tissues.
