Effect of nitrite and nitrate supplementation on the levels of nitrite and nitrate in whole blood.

<p>C57BL/6 mice were divided into three groups. Control group received normal water (no treatment), second group received nitrite (0.1 g/L)-containing water and the third group received nitrate (1 g/L)-containing water for a week. All groups were fed standard diets during the treatment period. Nitrite (A) and nitrate (B) in the whole blood from each group were measured using a chemiluminescence NO analyzer (Sievers, Model 280 NO analyzer). Data are means ± SEM (n≥4). * p<0.05.
