After fixation by low pressure retrograde perfusion the electron microscopic picture of the rat JGA was studied and compared with the picture obtained after fixation by dripping and immersion. The most conspicuous difference was the presence of the basal compartments of the macula densa cells, which might land electron microscopic support to the tubulo-glomerular feedback theory. Among the JG granular cells, desmosome-like connected structures were seen. Crystalline and granule in granules specific secretion forms were frequent in the epitheloid cells.
通过低压逆行灌注固定后，研究大鼠球旁器（JGA）的电子显微镜图像，并与通过滴注和浸泡固定后获得的图像进行比较。最显著的差异是致密斑细胞基底室的存在，这可能为肾小管-肾小球反馈理论提供电子显微镜支持。在球旁颗粒细胞中，可见类似桥粒的连接结构。上皮样细胞中常见晶体和颗粒等颗粒特异性分泌形式。
