The juxtaglomerular apparatus in the kidney of the domestic fowl was studied with the light and electron microscope after fixation by vascular perfusion. The height of the macula densa cells was greater and the internuclear distance less than were those of other distal tubule cells. Goormaghtigh (lacis) cells were found in the angle between the hilar arterioles and the glomerulus. The branching pattern of the basement membrane of the macula densa was extensive, surrounding both the Goormaghtigh cells and the mesangial cells. The basement membrane ended in the walls of both hilar arterioles and in the glomerular capillaries. Thus, all juxtaglomerular and glomerular structures were linked together by the branches of basement membrane. The afferent and efferent arterioles were often found ramifying in the mesangial cell mass. Granular epithelioid cells and adrenergic nerves were found within the glomerulus.
采用血管灌注固定法，用光镜和电镜对家鸡肾脏的球旁器进行了研究。致密斑细胞的高度比其他远曲小管细胞更高，核间距更小。在肾门小动脉与肾小球之间的夹角处发现了球外系膜（拉西斯）细胞。致密斑的基底膜分支广泛，围绕着球外系膜细胞和系膜细胞。基底膜终止于肾门小动脉壁和肾小球毛细血管壁。因此，所有球旁和肾小球结构都通过基底膜分支连接在一起。入球小动脉和出球小动脉常分支于系膜细胞团内。在肾小球内发现了颗粒状上皮样细胞和肾上腺素能神经。
