ラットの生体内ミネラル状態に及ぼすセレン欠乏の影響 -トルライーストとカゼインの比較

抄録

TY supplied a large extra minerals (Na, K, Ca, Mg, Fe, Mn, Zn, & Cu) than VFC except Se. Se and GSHPx activity were lower in TY-fed rats than VFC-fed rats and in -Se rats than +Se rats. Fe was higher in liver and muscle of VFC-fed rats and in plasma, heart, liver, and tibia of TY-fed rats fed -Se diet compared to the rats fed +Se diet, respectively. Compared to +Se rats, decreases of Mn concentration appeared in plasma, heart, and tibia of VFC-fed -Se rats and in brain, heart, liver and tibia of TY-fed -Se rats, respectively.

The results indicated that Se deficiency induced minerals imbalance in rat especially increase in Fe and decrease in Mn which was more severe in TY-fed rats than VFC-fed rats. TY can not be used to make a model for both Se and one of other minerals, e.g. Mg, deficiency because of the extra minerals except Se.
