[The pathomorphological changes in the pleura of rabbits with artificial pneumothorax and uropolin pleurography].

The results from artificial pneumothorax in 25 rabbits with intrapleural administration of Uropolin (10 rabbits) as well as of 10% solution of NACl (7 rabbits) were described. Thoracotomy was made on 7th, 14th and 12 21st day and the parietal, diaphragmatic and visceral pleura with underlaying tissues were examined. Proliferation of the mesothelium [correction of mesother] and growth of the connective tissue, which were more manifested in rabbits treated with Uropolin, were established histologically. The authors think that pathohistological examinations confirm the clinical observed favourable effect of intrapleural administration of Uropolin for obliteration of the pleural cavity.
