Blood vascular beds of the rat adrenal gland were filled with methacrylate resin and observed with a scanning electron microscope. The classical findings on mammalian adrenal glands of Flint (1900), Bennett and Kilham (1940), and Gersh and Grollman (1941) were confirmed. The cortical capillaries arise from the cortical arteries and converge at the corticomedullary junction into the peripheral venous radicles which flow into the tributaries of the central vein. The medullary capillaries originate from the medullary arteries and drain through the deep venous radicles into the tributaries of the central vein. No direct connection between the cortical and medullary capillaries was noted except for rare communications via the peripheral venous radicles. These findings show that most of the cortical blood, rich in glucocorticoids, flows in the medulla, not through the medullary capillary plexus but exclusively through the radicles of the central vein. Evidence for adrenal portal vessels could not be found.
将大鼠肾上腺的血管床用甲基丙烯酸树脂填充，并用扫描电子显微镜观察。弗林特（1900年）、贝内特和基尔汉姆（1940年）以及格什和格罗尔曼（1941年）关于哺乳动物肾上腺的经典研究结果得到了证实。皮质毛细血管起源于皮质动脉，在皮质髓质交界处汇合形成外周静脉分支，这些分支流入中央静脉的支流。髓质毛细血管起源于髓质动脉，并通过深部静脉分支引流到中央静脉的支流。除了通过外周静脉分支的罕见连通外，未发现皮质和髓质毛细血管之间有直接连接。这些发现表明，富含糖皮质激素的大部分皮质血液在髓质中流动，不是通过髓质毛细血管丛，而是仅通过中央静脉的分支。未发现肾上腺门脉血管的证据。
