Abstract

The nutrient pathway to the flexor tendons within the digital flexor sheath of adult chickens was investigated using tritiated proline. There was no difference in the uptake of the radioactive tracer by free segment tendons (detached from blood vessels) and the intact tendon lying in synovium. The uptake of tracer by tendons isolated from the synovium (but with unaltered vascular attachments) was significantly less than by the intact tendons. Radioactive tracer not only diffused across the synovium into the tendon, but along the course of the tendon itself. There was no difference in the uptake of radioactive tracer by 2-week-old tendon grafts with and without adhesions.

摘要

利用氚标记的脯氨酸对成年鸡指屈肌鞘内屈肌腱的营养途径进行了研究。游离段肌腱（与血管分离）和位于滑膜内的完整肌腱对放射性示踪剂的摄取没有差异。从滑膜中分离出的肌腱（但血管附着未改变）对示踪剂的摄取明显少于完整肌腱。放射性示踪剂不仅穿过滑膜扩散到肌腱中，而且沿着肌腱本身的走行扩散。有粘连和无粘连的2周龄肌腱移植物对放射性示踪剂的摄取没有差异。
