[The mechanisms of adrenergic and cholinergic effects on the lymphatic vessels of reptiles].

Adrenaline and acetylcholine were shown to induce a dose-dependent increase in tonic tension of isolated strips of the tortoise lumbar lymphatic cistern and the lizard cardinal lymphatic vessel. The affinity of adrenaline to receptors in the lizard lymphatic vessel was higher than in the tortoise lymphatic vessels, whereas the affinity of acetylcholine was higher in tortoises.
