Characterization of the rat parotid beta-adrenoceptor. 1981

B Carlsöö, and A Danielsson, and R Henriksson, and L A Idahl

1 The effects of various beta-adrenoceptor agonists on amylase secretion from the rat parotid gland were studied by means of two different in vitro techniques. 2 The dose-response relation for each agonist was established, as also were the ED50 values. 3 All drugs appeared to act directly on the acinar cells, as reserpine-treatment did not abolish their secretagogic effects. 4 Two groups of agonists could be distinguished: one group consisting of adrenaline, noradrenaline and the B1-selective agonist prenalterol (H133/22) with a high enzyme discharge potency and a second group consisting of the beta 2-agonists, terbutaline and salbutamol, with a markedly lower effect. 5 The present data further support the theory that rat parotid acinar cells are supplied mainly with beta-adrenoceptors of the beta 1-subtype, similar to those present in heart and adipose tissue.

UI	MeSH Term	Description	Entries
D010306	Parotid Gland	The largest of the three pairs of SALIVARY GLANDS. They lie on the sides of the FACE immediately below and in front of the EAR.	Gland, Parotid,Glands, Parotid,Parotid Glands
D011941	Receptors, Adrenergic	Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction.

D011943	Receptors, Adrenergic, beta	One of two major pharmacologically defined classes of adrenergic receptors. The beta adrenergic receptors play an important role in regulating CARDIAC MUSCLE contraction, SMOOTH MUSCLE relaxation, and GLYCOGENOLYSIS.

D012110	Reserpine	An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.

D000681	Amylases	A group of amylolytic enzymes that cleave starch, glycogen, and related alpha-1,4-glucans. (Stedman, 25th ed) EC 3.2.1.-.	Diastase,Amylase
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
