Total nitrite concentrations in rat tissues. (A) Tissue samples were homogenized by a rotary homogenizer40, then centrifuged (17,000 g, 30 min) after mixing with methanol for deproteinization. The supernatant was used for nitrite content measurement using a standard chemiluminescence method with triiodide. Data are plotted as average ± standard deviation (n = 4 ~ 6, * p < 0.05). (B) The change in each organ at 1-day and 3-day Na15NO3 supplementation (1 g/L) relative to control.
