Background: Cyclin D1 proto-oncogene is an important regulator of (G1 to S) phase progression in many different cell types. The Aims of this study were to evaluate the immunohistochemical expression of Cyclin D1 in mucoepidermoid and adenoid cystic carcinoma of the salivary glands and to correlate the immunoexpression of this protein with the clinicopathological findings. Materials and methods Retrospectively, twelve of archival formalin fixed paraffin embedded tissue samples of salivary Mucoepidermoid and fourteen blocks of adenoid cystic carcinomas obtained from the archives of the department of oral pathology / college of dentistry / Baghdad university, Al-Shaheed Ghazi hospital, were included in this study. Five micrometer sections obtained and immunostained using monoclonal antibody against Cyclin D1. The immunoexpression was detected by the presence of brown stain in the nucleus of tumor cell. The proportion of cells that expressed the stain was correlated with the clinicopathological data of the patients. Results: Cyclin D1 expression was found positive in all cases of MEC and AdCC localized in tumor cells. Non-significant statistical relation (p=0.588) was detected regarding Cyclin D1 expression in both types of tumor. Significant relation was found with stage of AdCC (p=0.04) and non-significant concerning other clinicopathological parameters in both tumor types. Conclusion: Weak expression of Cyclin D1 in MEC and AdCC might be explained by Cyclin D1 does not represent an exclusive factor consequently; other factors might be involved in the proliferation, progression and metastasis of both tumor types.
The article attempts to provide the theoretical fundamentals for the semiotic component of lacunae in a language. The definitions of the following notions have been represented: 1) lacunarity as a complex phenomenon that works in the modes of language, speech and speech behaviour; 2) lacuna as a gap, an empty space, which lacks something, which may be characteristic of a written work. The author of the article considers the main classes of lacunae, among which are: 1) generic lacunae, which reflect the absence of a common name for a class of objects; 2) species lacunae are the absence of specific names, names of individual types of objects or phenomena; 3) intralingual lacunae are found within the paradigms of one language; 4) interlanguage
