RADIOACTIVE IRON ABSORPTION BY GASTRO-INTESTINAL TRACT

Radioactive Iron Absorption by Gastro-intestinal Tract

Iron absorption is a function of the gastro-intestinal mucosal epithelium. The normal non-anemic dog absorbs little iron but chronic anemia due to blood loss brings about considerable absorption-perhaps 5 to 15 times normal. In general the same differences are observed in man (1). Sudden change from normal to severe anemia within 24 hours does not significantly increase iron absorption. As the ...

Absorption of radioactive iron by anaemic infants.

The oral administration of iron to anaemic infants often fails to restore the haemoglobin level as rapidly as it would in an adult. The reason for this failure could be either failure of absorption or failure to utilize the iron which had been absorbed, or deposition of all the iron in the tissue stores without any being incorporated in the haemoglobin. It was therefore decided to study the abs...

Functional Disorders of the Gastro-Intestinal Tract

Diabetes and the gastro-intestinal tract.

The autonomic nervous supply to the gut is affected by long standing diabetes. These may be responsible for the disorders of the gut. Segmental demy-elination, reduction in size of the neurons, altered vasoactive intestinal poly-pepticle (VIP), somatostatin (SS) and substance P in these neurons supplying the gut and axonal degeneration in the meissneri plexus are the abnormalities found in diab...
