Influence of combined nitrate and fluoride intoxication on connective tissue disorders in rats gastric mucosa

Abstract

We established that chronic excessive fluoride or nitrate intake can cause oxidative and nitrosative stress-depended collagen degradation, simultaneously decreasing the concentration of anti-inflammatory GAG. Combined intoxication leads to even more severe connective tissue degradation, but subsequently activates compensatory mechanisms through increase in concentration of anti-inflammatory GAG.
