Popis: | The Harderian gland of rabbits has been studied with light and electron microscopes. The red part contains relatively wide alveoli with an irregular cuboidal epithelium. The stainability of the cytoplasm is poor. The white part has smaller alveoli with a low columnar epithelium. The cells show cytoplasmic basophilia removable with ribonuclease. The cytoplasm of both kinds of cells is very dense when examined in the electron microscope. The mitochondria show branched, closely packed cristae and a dense matrix. The Golgi apparatus displays few lamellae and rows of vacuoles. The endoplasmic reticulum is very finemeshed and partly associated with ribonucleoprotein particles. Both kinds of cells contain numerous lipid droplets, leaving vacuoles in the sections prepared for electron microscopy. They are fewer but distinctly larger in the red part. In both lobes pictures suggesting a secretion of lipid droplets have been observed. Cells showing signs of degeneration with subsequent discharge of the detritus have been observed in both lobes, but this process does not correspond to the “holocrine” secretion in sebaceous glands. Likewise, no apocrine secretion was observed. |
