In complete series of histological sections through the entire abdomen of one normal Wistar-rat, one untreated and two bilaterally adrenalectomized, spontaneously hypertensive Wistar-rats accessory suprarenal glands were found in each case. The detailed findings in the various groups of animals investigated were as follows: (1) In the normal animal 10 accessory suprarenal glands were present. They consisted of tiny aggregates of cortical cells and were surrounded by a thin layer of collageneous fibers. The diameters of the accessory suprarenal complexes were in the order of 0.3 mm. (2) In the untreated, spontaneously hypertensive rat three accessory suprarenal glands were found. However, in contrast to what was seen in the normal rat, these complexes were larger and had diameters of up to 1 mm. Some of these accessory suprarenal glands consisted almost exclusively of small, chromophobe cells, whereas in others a rim of such cells was seen to surround a central core of larger and more acidophile cortical cells. There were few and collapsed capillaries. (3) In the bilaterally adrenalectomized, spontaneously hypertensive rats three, respectively four, accessory suprarenal glands were found. They were situated in the retroperitoneum and partly within the adipose capsule of the kidney but never in the place of the exstirpated main suprarenal glands. In one case an accessory gland was found within the fibrous capsule of the kidney and seen to compress the renal parenchyma. In the bilaterally adrenalectomized animals the average diameters of the accessory glands were larger than in the other groups reaching values of up to 5 mm. At least in both animals one of the accessory glands had a diameter comparable to that of the normal suprarenal gland of an untreated animal. The capillaries were dilated and their number was increased in comparison to what was seen in the other groups. In certain regions the cortical tissue of the accessory glands had an appearance resembling that of zona fasciculata and reticularis.
在对一只正常Wistar大鼠以及一只未处理的和两只双侧肾上腺切除的自发性高血压Wistar大鼠的整个腹部进行的完整组织学切片系列中，每种情况下均发现了副肾上腺。对所研究的不同动物组的详细发现如下：（1）在正常动物中，存在10个副肾上腺。它们由皮质细胞的微小聚集体组成，并被一层薄薄的胶原纤维包围。副肾上腺复合体的直径约为0.3毫米。（2）在未处理的自发性高血压大鼠中，发现了3个副肾上腺。然而，与正常大鼠中所见不同的是，这些复合体更大，直径可达1毫米。这些副肾上腺中的一些几乎完全由小的嫌色细胞组成，而在其他副肾上腺中，可以看到这样的细胞边缘围绕着较大且嗜酸性更强的皮质细胞的中央核心。毛细血管稀少且塌陷。（3）在双侧肾上腺切除的自发性高血压大鼠中，分别发现了3个和4个副肾上腺。它们位于腹膜后，部分位于肾脂肪囊内，但从未在已切除的主肾上腺的位置。在一个病例中，在肾纤维囊内发现了一个副肾上腺，并观察到它压迫肾实质。在双侧肾上腺切除的动物中，副肾上腺的平均直径比其他组更大，可达5毫米。至少在两只动物中，其中一个副肾上腺的直径与未处理动物的正常肾上腺相当。与其他组相比，毛细血管扩张且数量增加。在某些区域，副肾上腺的皮质组织外观类似于束状带和网状带。
