Figure 1: Serum iron profile levels in rats after N.O administration. (a) Total Iron (T.I) level continuously elevated after 3 h up to the studied time point. (b) Serum ferritin (F) showed increase only at 12 h with sudden decrease thereafter. (c) Total iron binding capacity (TIBC) levels in serum are shown with overall decline in the parameter, when compared to control values which were transformed to zero. These results are representative of three animal series (statistically significant at ; mean ± SEM).
