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.
研究了多巴胺对盲肠运动的影响。实验在4只患有盲肠慢性瘘管的绵羊身上进行。采用气囊法记录盲肠的收缩情况。以29 - 38微克·千克⁻¹·分钟⁻¹的速率静脉注射多巴胺可抑制盲肠运动。在β - 肾上腺素能阻滞剂普萘洛尔（0.5 - 1.0毫克·千克⁻¹）之后注射多巴胺可抑制盲肠运动，然而在多潘立酮（0.2 - 0.4毫克·千克⁻¹）之后注射多巴胺则不会改变其运动。得出的结论是，多巴胺通过特定的多巴胺能受体抑制绵羊的盲肠运动。
