Abstract
Summary
Adult Sceloporus cyanogenys were treated with 250 μg of estradiol valerate for 5, 11, 15 and 42 days. The bones were studied histologically and the plasma chemistry was determined. No morphological changes were observed in the bones. The plasma calcium and inorganic phosphorus were significantly elevated from the controls within 5 days after the injection. The proteins did not increase significantly until 11 days after injection, and the elevation occurred only in the “gamma globulin” component. It is suggested that estrogen induces increased “gamma globulin” synthesis whose origin is in part in the reticuloendothelial system.
