    Author: Zieba D, Wegrzyn T, Cebrat E, Leroch Z.
    Journal: Pol Arch Weter; 1991; 31(1-2):109-14. PubMed ID: 1821029.
    Abstract:
    The influence of dopamine on the motility of the caecum were studied. The experiments were carried out on 4 sheep with chronic fistulas of the caecum. The contractions of the caecum were recorded by the balloon method. Dopamine infused intravenously at a rate 29-38 micrograms.kg-1.min-1 inhibited the motility of the caecum. Dopamine infused after beta-adrenergic blocker propranolol (0.5-1.0 mg.kg-1) inhibited the movements of the caecum, however administrated after domperidone (0.2-0.4 mg.kg-1) didn't change its movements. It has been concluded that dopamine inhibits the caecum motility in sheep through specific dopaminergic receptors.
