Functional studies of the ureter: its behaviour in the domestic pig (Sus scrofa domestica) as recorded by the technique of Trendelenburg.

摘要: SUMMARY 1. The ureter of the domestic pig was examined histologically. muscle coat does not have two distinct layers: probably there is a spiral arrangement single coat. 2. Even with specialised stains no sign plexus nerve fibres and cells as in niyenteric gut: were seen only adventitia. 3. lends itself to study vitroin Trendelenburg's apparatus. 4. Acetylcholine has powerful motor action easily abolished by atropine. 5. Noradrenaline adrenaline are also powerfully action. In presence phenoxybenzamine this effect replaced inhibition. 6. lsoprenaline inhibitor inhibition pronethalol. 7. There seem therefore be α β adrenergic receptors ureter. 8. discussion speculation about significance such findings for an explanation vesico-ureteric reflux man.
