Abstract:
:We analyzed the effects of acute and chronic oral administration of monosodium L-glutamate (MSG) on serum iron (Fe) levels and total iron-binding capacity (TIBC) in piglets. In the first experiment, 12 piglets were randomly assigned to two groups: one fed a standard diet (SD) and the other fed an SD containing MSG (10 g/kg). On day 30, serum, liver, kidney, and spleen samples were collected to determine the Fe levels. In the second experiment, six pigs were surgically fitted with a catheter in the jugular artery and vein to investigate the dynamic changes of serum Fe and TIBC. Blood samples were taken from each pig via the catheter every 30 min, for a period of 4 h. The results show that MSG increases Fe levels in the spleen (P < 0.05) and in serum obtained from the jugular artery (P < 0.01). In addition, TIBC in serum obtained from the jugular artery demonstrated an increasing trend in pigs fed the MSG diet; however, this trend was not observed in the jugular vein. In conclusion, MSG increases Fe retention by enhancing TIBC in serum.
