Tenascin-C In Betel-Quid Associated Lesions, Rosnah Binti Zain, Fukano H., Ikeda N., Kudeken W., Shrestha P., Ghazali M. N., Takai Y., Mori M.

Prof. Dr. Rosnah Binti Zain

The expression of Tenascin-C, an adhesion modulating or anti- adhesive extracellular matrix protein, was evaluated in betel quid associated lesions of oral mucosa showing focal hyperkeratosis (n=15), dysplasia (n=15), oral submucous fibrosis (n=7) and oral squamous cell carcinoma (n=8). All the patients were chewers of betel quid containing betel leaves, areca nuts, lime and tobacco. The results obtained from this study were compared to similar lesions in smokers and non-quid users cited in the literature (Shrestha et al, Oral Oncol, 1994). An enhanced expression of TN-C was observed in epithelial connective tissue interface of quid associated hyperkeratotic and dyplastic mucosa. …


Pcna Expression In Epithelial Linings Of Odontogenic Cysts And Unicystic Ameloblastoma, Sudiono J., Rosnah Binti Zain Apr 1999

Pcna Expression In Epithelial Linings Of Odontogenic Cysts And Unicystic Ameloblastoma, Sudiono J., Rosnah Binti Zain

Prof. Dr. Rosnah Binti Zain

Proliferating cell nuclear antigen (PCNA) is a nuclear protein synthesized in the late G1 and S phase of the cell cycle. It is a useful marker for the proliferating fraction of cells in tissue specimens. The purpose of this study was to describe the expression of PCNA within epithelial linings of odontogenic cyst and to compare the proliferative activities of these lesion using PCNA labeling indices. A total of 61 cases of odontogenic cysts and unicystic ameloblastomas (18 radicular cysts, 16 dentigerous cysts, 15 odontogenic keratocysts (OKC) an 12 unicystic ameloblastomas) was studied. It was found that PCNA staining were …
