A morphometric study of the secretory granules of the granular duct in the submaxillary gland of the rat following stimulation with noradrenaline and isoproterenol.

چکیده
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.

P-26: Histomorphological Study of Rat Prostate Gland
Background: Rat prostate gland which is used in various investigation has considerable morphological differences with other mammals. There are few reports about its structure. So, this study was carried on for determining of histomorphological structure of rat prostate. Materials and Methods: Five healthy adult male rats with average weight 20 ± 180 g and approximately 3 - 3.5 months age were s...

BACKGROUND: In the present study, the submandibularsalivary gland microscopic morphology of the adult Africangiant pouched rat was investigated. This study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. This becomes of evenhigher importance when considering th...

growth of the prostate gland, also development of benign prostatic hyperplasia (BPH) is an androgen-dependent functions. Testosterone plays a major role in the prostate gland. Rat prostate gland is one of the most widely used models of animals in investigation. The rat prostate gland consisted of five lobes; the ventral, anterior, dorsal, lateral type 1 and latteral type 2. The goal of present ...

The effects of in vivo administration of prostaglandin E1 (PGE1) on rat parotid gland acinar cells were studied and compared with glands removed from animals which had been either fasted or stimulated to discharge stored secretory granules by an injection of isoproterenol (IPR). Depletion of tissue amylase, increased plasma amylase, and alterations in secretory cell ultrastructure were used to ...

The fine structure of von Ebner's gland was studied in untreated rats and rats stimulated to secrete by fasting-refeeding or injection of pilocarpine. Cytological features were similar to those reported for pancreas and parotid gland. Abundant granular endoplasmic reticulum filled the basal portion of the cell, a well-developed Golgi complex was located in the vicinity of the nucleus, and the a...
