Assessment of Salivary and Serum Proteins in Patients with Oral Tumors

Abstract

The qualified subjects for this study included 33 patients with benign and malignant oral tumors aged 15-75 years and 31 matched age and gender healthy subjects used as control. Proteins measurements included total protein, albumin, globulines in sera and saliva samples, and immunoglobulins (IgG, IgM, IgA) in sera samples of control and patients. Meanwhile, polyacrylamide gel electrophoresis (PAGE) was used to differentiate between protein patterns in both serum and saliva samples among the studied groups. The gel was also stained for glycoprotein to evaluate as well the changes in glycoprotein contents. For total protein, the results revealed a signifigant increase (P?0.01) in both samples (serum and saliva) of patient group. Albumin concentration shows presence of a high significant decrease (P=0.001) in sera samples but a significant increase (P<0.05) in saliva of the patients group in comparison to that of control group. Immunoglobulins concentrations also show significant increase in patients group in comparison to control group. This study aimed to estimate salivary and serum proteins in oral cancer patients and in healthy control group to evaluate their role in diagnosis and prognosis of oral cancer
