title: A morphometric study of the secretory granules of the granular duct in the submaxillary gland of the rat following stimulation with noradrenaline and isoproterenol.
abstract: In the present work, we carry out a morphometric analysis, at ultrastructural level, of the secretory granules of the granular undulated duct of the submaxillary gland of the rat, under basal conditions (Control Group or I), following stimulation for 10 minutes with 2 mg/100 g weight of Isoproterenol (Group II), and following stimulation with 2 gammas/100 g weight of Noradrenalin for the same time as in the former case. It is seen that in general, Noradrenalin produces the appearance of a greater number of small granules than does Isoproterenol or the control group; and that Isoproterenol induces the presence of larger-sized granules than does Noradrenalin.
