Spongy bones in prehistoric America.

A well-preserved mummified child from about A.D. 1200 was recovered fron Canyon de Chelly in northeastern Arizona in 1971. Striking skull changes were found and microscopic, ultrastructural, and cytochemical studies confirm the diagnosis of porotic hyperostosis that resulted in spongy bone appearance. We suggest that a possible cause for this condition could be iron deficiency of a severity seldom found in modern societies.

Angiotensin II: rapid localization in nuclei of smooth and cardiac muscle.

Five to ten nanograms of labeled angiotensin II rapidly injected in the left ventricle of adult rats was found to induce significant ultrastructural endothelial changes, resulting in net increases in number and size of pinocytotic vesicles as well as widening of intercellular spaces. This effect was followed by preferential localization of the compound in the nuclear zone of vascular and cardiac muscle cells. The selective cellular localization of angiotensin II suggests that this vasoactive agent or some of its metabolic fragments may have specific effects on nuclear function.
