The Schultz-Dale reaction of the guinea-pig ileum: influence by beta-adrenoceptor agonists and theophylline

Agents and Actions

Abstract

One of the organs that can be used to study the Schultz-Dale reaction, is the guinea-pig ileum. The reaction is characterized by a specific pattern: a quick contraction, followed by a quick relaxation and a second, more slow contraction. A description is given of this typical reaction. Selective inhibition of the slow contraction could be obtained using beta-adrenoceptor agonists. Also theophylline inhibited the slow contraction, but this inhibition was only selective within a narrow range of concentration. These findings encourage further investigation about a possible involvement of cyclic nucleotides in the liberation of the mediators involved in the Schultz-Dale reaction of the guinea-pig ileum. Furthermore they provide more information about this preparation which could be used as a screening model for anti-allergic drugs of distinct pharmacological groups.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
