Levels of biological markers of nitric oxide in serum of patients with squamous cell carcinoma of the oral cavity.

The aim of the study was a determination of the levels of nitric oxide (NO) and its biological markers such as malonyldialdehyde (MDA) and nitrotyrosine in the serum of patients with squamous cell carcinoma (SCC) of the oral cavity and identification of the relationships between NO and those markers. These studies were performed on patients with SCC of the oral cavity before and after treatment. Griess reaction was used for the estimation of the total concentration of NO in serum.

Overexpression of B cell-activating factor (BAFF) in neutrophils of oral cavity cancer patients - preliminary study.

In the present study the expression of tumor-promoting B cell-activating factor (BAFF), a member of the tumor necrosis factor superfamily (TNF) in neutrophils from oral cavity cancer patients, was examined by real-time PCR. For the purpose of comparison, the expression of BAFF protein was assessed in autologous peripheral blood mononuclear cells (PBMCs). An important question of this study has also been to explain the role of NF-κB in the induction of BAFF molecule.

Tryptophan and its metabolites in patients with oral squamous cell carcinoma: preliminary study.

Purpose: It has been showed that tryptophan (TRP) degradation has been linked to modulation of cancer cell proliferation. The aim of our study was to estimate the concentration of TRP and its derivatives, such as anthranilic (AA) and kynurenic acid (KYNA) in plasma, saliva, squamous cell carcinoma (SCC) tissues and healthy oral mucosa in patients with oral SCC.

Material And Methods: The study was performed on plasma, non-stimulated, mixed saliva and squamous cell carcinoma tissues and healthy oral mucosa in patients with oral SCC.

Evaluation of secretory mucin concentration of patients with squamous cell carcinoma oral cavity.

Purpose: Secretory salivary mucins constitute a heterogenous group of glycoproteins, synthesized and secreted by submandibular, sublingual gland and small glands of oral mucosa. The most significant functions of mucins in case of oral cavity carcinoma are: participation in oral pellicle formation, lubrication and creation of heterotypic complexing. The aim of this study was to assess mucins concentration, and finally to establish the correlation between concentration of mucins in saliva and clinical advancement according to TNM.
