Abstract
Abstract Objective In this study, we aimed to investigate the changes in the levels of oxidative stress and antioxidant enzymes on the mandibular bone caused by the expression of aquaporin-1 and aquaporin-3 proteins. Material and method 14 Balb/C white mice were divided into two groups of seven, based on whether they are young or old. Mandibular tissue samples were taken for biochemical and histological analysis. Results Findings of our study has shown that, AQP-1 and AQP-3 immunoreactivity significantly decreased in mandibular bone tissues of aged mice in comparison to younger mice (p < 0.05). MDA and AOPP levels, which are the indicators of oxidative stress, increased in elderly mice and antioxidant defense system SOD enzyme activity was decreased (p < 0.05). The TNF-α cytokine level, which is the indicator for inflammations, was found to be higher in older mice than in young mice (p < 0.05). Conclusion As a result, it was observed that cellular damage, disruption in water – electrolyte balance and increased inflammation that occur during the natural process of aging had caused serious and irreversible disturbances.
