1.对大鼠肾上腺、黄体、内膜、颗粒膜、睾丸间质细胞和胎盘的线粒体进行了电子显微镜观察。2.在大多数类固醇分泌部位，线粒体的内部结构不是板状的，而是线粒体膜的管状反射。3.肾上腺线粒体的大小变化很大，甚至在单个细胞内也是如此；它们的直径可达2-3微米，几乎充满了小管。4.有人认为，虽然线粒体在许多地方都有管状成分，但肾上腺中的线粒体由于其巨大的尺寸和内部结构而高度专业化。
1. Mitochondria of the adrenal gland, corpus luteum, theca interna and granulosa of the graafian follicle, interstitial cells of the testis, and placenta of the rat have been studied with the electron microscope. 2. In most sites of steroid secretion, the internal structure of the mitochondria is in the form of tubular reflections of the internal mitochondrial membrane, rather than plate-like cristae. 3. The mitochondria of the adrenal gland have a highly variable size, even within a single cell; they may reach 2 to 3 µ in diameter, and are nearly filled with tubules. 4. It is suggested that while mitochondria in many places have a tubular component, those in the adrenal gland are highly specialized by virtue of their giant size and their internal structure.
