The Impact of Hepatitis C Virus Genotypes on Oxidative Stress Markers and Catalase Activity.

Hepatitis C virus (HCV) is a major cause of liver disease worldwide. Chronic HCV infections are usually associated with increased oxidative stress in the liver tissue. The intensity of oxidative stress may be a detrimental factor in liver injury and may determine the severity of the disease.

Determination of Salivary Myeloperoxidase, Immunoglobulin E, and Tumor Necrosis Factor-α after Complete Denture Insertion.

Objective: To detect activities of salivary myeloperoxidase (MPO) and concentrations of salivary tumor necrosis factor (TNF)-α as indicators of inflammatory reaction and salivary immunoglobulin E as an indicator of allergic reaction after complete insertion of acrylic dentures.

Subjects And Methods: Complete dentures were made for a uniform group of elderly patients, and saliva samples were taken immediately before they were given to the patients, as well as 2, 3, 7, and 30 days after insertion of the dentures, with simultaneous monitoring of changes in the oral mucosa.

Results: After 7 and 30 days of wearing upper and lower complete dentures, nonsignificant increases in salivary MPO and TNF-α were proven to be indicators of inflammation.
