Inhibitory effect of colchicines on amylase secretion by rat parotid glands: possible localization in the golgi area

Inhibitory effect of colchicines on amylase secretion by rat parotid glands: possible localization in the golgi area

Colchicine inhibited amylase secretion by isolated rat parotid glands only 6 h after administration of the drug in vivo. This delayed effect was not the result of the inability of the drug to reach its reaction site. When parotid glands were emptied of their secretory granules by isoproterenol treatment, the subsequent replenishment of cells with granules was inhibited by colchicines. Colchicin...

Immunohistochemical and Immunocytochemical Localization of Amylase in Rat Parotid Glands and von Ebner’s Glands by Ion Etching-Immunoscanning Electron Microscopy

The distribution of amylase in rat parotid glands and von Ebner's glands was examined using ion etching-immunoscanning electron microscopy, which enables both light and electron microscopic observations of identical semi-thin resin sections immunolabeled with anti-α-amylase and immunogold in association with silver enhancement. At the light microscopic level, most acinar secretory granules (SG)...

Amylase mRNA synthesis and ageing in rat parotid glands following isoproterenol-stimulated secretion.

In the parotid, as well as in other exocrine glands, secretory protein synthesis declines with age. However, whether this decline in the steady-state rate of protein synthesis reflects the reduced digestive activity of the animal or actual cellular alterations that affect synthesis is unknown. Here the ability to synthesize amylase and its mRNA during the period of enhanced protein synthesis fo...
