Abstrakt		Osmium impregnation was used to show possible differences of reduction capacity of perinuclear space, rough endoplasmic reticulum and the Golgi apparatus of unstimulated mouse parotid gland and in the gland after repeated pharmacological doses of isoproterenol. There were some significant differences between the staining of acinar and duct cells. In all intercalated and striated duct cells the staining is dense in the perinuclear space and in the rough endoplasmic reticulum. Osmiophility was not detected in the Golgi complex of intercalated duct cells. The staining was also lacking in the perinuclear space and endoplasmic reticulum of the acinar cells. The cis face of the Golgi complex and numerous transitional vesicles in the acinar cells showed variability of the reduction capacity of their membrane segments. In chronically treated acinar cells Os black was lacking in the Golgi cisternae, except that the numerous transitional vesicles were heavily stained. These results reveal characteristic differences of reduction capacity of endomembrane compartments in different parotid glandular cells, as well as between untreated and treated acinar cells.
