Abstract

Reticulated-siderocytes (reticulocytes which contain siderotic granules), obtained from the circulation of pigs after vigorous phlebotomy, were incubated in vitro. A rapid disappearance of granules from the reticulocytes was observed over 24 hr. Simultaneously with the decrease in granules, soluble ferritin accumulated in the media and siderotic granules developed in monocytes. The disappearance of the granules from the reticulated-siderocytes was oxygen-dependent and the loss of granules and the accumulation of ferritin in the media were both prevented by the addition of cyanide or dinitrophenol.
