ANF IN THE PAROTID GLAND IN RABBIT.

Abstract

It is well known that the presence of a particular type of granule population has been discovered in the atrial cardiocytes which represent the major site of synthesis of atrial natriuretic factor. The ANF has potent natriuretic, diuretic and vasoactive functions. However, ANF evidence occurs in extracardiac tissues such as the brain, intestine, lymphoid organs and in various glands involved in water and salt regulation adrenals, pancreas, lacrimal and salivar glands with respect to salivary glands the literature reportes that ANF presence was found in the acinar cells and on the contrary in the ductal cells. In order to eliminatethese discordances researchers conducted a previous study on rabbit parotid gland. The observations evidenced that the acinar cells were immunonegative while the ductal intraparenchymal cells were immunopositive in the present research we have extended the study on the main excretory duct of rabbit parotid gland.
