    Notizen: Summary Coiled bodies were investigated by means of ultrastructural cytochemistry. Preferential staining methods for localization of various proteins (ribonucleoproteins, basic proteins, phosphoproteins and glycoproteins) and DNA were applied. The results of cytochemical tests revealed that coiled bodies have a proteinaceous nature. They are composed of ribonucleoproteins, probably of nucleolar origin. They also contain phosphoproteins and glycoproteins but lack cytochemically detectable DNA. Coiled bodies present ultrastructural and cytochemical characteristics similar to the fibrillar part of the nucleous and to the interchromatin granules. The origin and possible functional role of coiled bodies are briefly discussed.

    Notizen: Summary Intracytoplasmic fibrillar inclusions, generally referred to as nucleolus-like bodies (NLBs) were studied by means of ultrastructural cytochemistry. The structure of these bodies was visualized by several different staining procedures: conventional electron microscopy and preferential staining methods for localization of various proteins including ribonucleoproteins, basic proteins, glycoproteins and phosphorylated proteins. The results of the cytochemical tests indicate that NLBs have an essentially proteinaceous nature. They consist of ribonucleoproteins, basic proteins and glycoproteins but do not contain phosphorylated proteins. These findings suggest that NLBs are, at least partially, of the same nature as nucleoli and coiled bodies. The origin of NLBs and their possible functional role is briefly discussed.
