| Research Abstract |
This study suggested that the inflammation of salivary glands play a critical role in pathological conditions in the elderly oral dryness. In model animal experiments, we found that Redox related genes, which were expressed characteristically similar to the inflammation related gene, and hyposalivation was correlated with oxidative stress of serum and saliva. These results indicated that the inflammation of salivary gland is due to oxidative stress, which is increased with aging and lifestyle disease.
