Abstract
After agar-agar and india ink mixture intrarenal injection, it is possible to measure precisely the glomerular afferent arteriole diameter and to evaluate its variations after theophylline perfusion. The increased diameter (+ 35.78%) confirms the peripheral vasodilating theophylline effect, often assumed, but never to our knowledge proven in situ.
摘要
在进行琼脂和印度墨水混合物肾内注射后，可以精确测量肾小球入球小动脉直径，并评估氨茶碱灌注后其变化情况。直径增加（+35.78%）证实了氨茶碱的外周血管舒张作用，这种作用通常被认为存在，但据我们所知，从未在原位得到证实。
