<unk>  means "loves eosin", and refers to the staining of certain tissues, cells, or organelles after they been washed with eosin, a dye.
Eosin is an acidic dye, thus the structure being stained is basic.<unk>  describes the appearance of cells and structures seen in histological sections which take up the staining dye, eosin. This is a bright pink dye that stains the cytoplasm of cells as well as extracellular proteins such as collagen.
Such<unk>  structures are generally composed of protein.
The stain eosin is usually combined with a stain called haematoxylin to produce a haematoxylin and eosin stained section (also called an H&E, HE or H+E section). This is the most widely used histological stain in medical diagnosis - for example when a pathologist looks at a biopsy of a suspected cancer they will have the section stained with H&E.
Some structures seen inside cells are described as being<unk> , for example Lewy bodies, Mallory bodies.
