Ultrastructural study on nuclear bodies of the rat parotid glands. 1991

Nuclear bodies of types I, II, III and IV are constantly present in rat parotid glands. They become apparent on the 21st day and afterwards. Type IV nuclear bodies were chiefly found in the striated ducts. Nuclei containing 3 and more nuclear bodies were found as early as the 3rd month, although only in the striated ducts. Nuclear bodies are not related to glycogen or DNA replication but probably to rRNA metabolism. This study leads to a better understanding of nuclear bodies modifications which can be observed ultrastructurally in human salivary glands pathology. Their increased number in some nuclei may be the expression of an alteration of the cell metabolism.

D001973 Bromodeoxyuridine A nucleoside that substitutes for thymidine in DNA and thus acts as an antimetabolite. It causes breaks in chromosomes and has been proposed as an antiviral and antineoplastic agent. It has been given orphan drug status for use in the treatment of primary brain tumors.

D002467 Cell Nucleus Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Cell Nuclei,Nuclei, Cell,Nucleus, Cell
D005260 Female Females
D006003 Glycogen
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
