Conservation of iron and hemoglobin during induced hemolytic stress in the amphibian Taricha granulosa

1. 1. The capability of Taricha granulosa to conserve hemoglobin upon in vivo hemolysis has been investigated. 2. 2. 59Fe incorporation into Taricha hemoglobin was similar in rate to mammals and birds. 3. 3. Phenylhydrazine-induced hemolysis resulted in comparatively low levels of 59Fe and no discer...

Zusammenfassung:	1. 1. The capability of Taricha granulosa to conserve hemoglobin upon in vivo hemolysis has been investigated. 2. 2. 59Fe incorporation into Taricha hemoglobin was similar in rate to mammals and birds. 3. 3. Phenylhydrazine-induced hemolysis resulted in comparatively low levels of 59Fe and no discernible amounts of hemoglobin excreted after 10 days. 4. 4. The addition of 59Fe Hb to Taricha circulation resulted in relatively low levels of 59Fe excretion and significant amounts of 59Fe incorporation into new hemoglobin within 10 days.
