Submicroscopic Structure of the Interphase Nucleus of Salivary Gland Cells under Experimental Conditions

抄録

Fine structural aspects of interphasic parotid gland cell nuclei treated with pilocarpine or atropine were the subject of observation. Pilocarpine caused an increase of the amount of interchromatin and perichromatin granules and a slight electrondensity of the interchromatinic substance. Atropine, on the other hand, caused a decrease or disappearance of perichromatin granules, an increase of the amount of interchromatin granules and electrondensity of the clumps of chromatin and interchromatinic substance, and the folding of the nuclear membrane. The authors described for the first time the occurrence of the so-called interchromatin canaliculi in the atropinized nuclei.
