Evidence of morphological modifications induced by theophylline in the epithelium of urinary bladder of rana esculenta


, : Evidence of morphological modifications induced by theophylline in the epithelium of urinary bladder of rana esculenta. Bollettino Societa Italiana Biologia Sperimentale 56(10): 1019-1023

The morpho-functional action induced by theophylline on bladder epithelium was studied. The epithelium treated with theophylline shows important structural variations. The whole tissue thickness appears reduced with cell disposed in monostratified layer. They show a light grade of swelling with nucleus and cytoplasm less evident and boundary less marked. The permeability of the epithelium does not appear modified.
