SUMMARY 1. Ethionine administered acutely to the adult female rat markedly elevates and then lowers plasma iron concentration over several days. Liver iron undergoes a reverse cycle. 2. Ethionine does not cause changes in the blood parameters, including total plasma iron‐binding capacity and plasma iron clearance. Erythrocytes of rats injected with ethionine show altered responses to hypertonicity. 3. Increased reticulo‐endothelial activity of the spleen, indicated by increased uptake of 59 Fe‐labelled erythrocytes by liver and spleen, apparently contributes to plasma iron elevation. Also the liver releases iron which further raises plasma iron.
