Abstract
INTRODUCTIONIN A previous study (Chung et al., 1966) delayed heterologous bone marrow and thymus transplantation resulted in decreased stearic acid content and increased palmitic, oleic, linoleic, and arachidonic acid content in liver tissues of pigeons. Irradiation has been known to decrease palmitic acid and to decrease polyunsaturated fatty acids (Hansen et al., 1965; Notario et al., 1965).To further explain these fatty acid changes we attempted to study the fatty acid changes in the liver lipid fractions of pigeons after lethal-dose radiation and delayed heterologous bone marrow, thymus, and spleen transplantation.MATERIALS AND METHODSNon-inbred sexually mature pigeons, 6–10 months of age, and descendants from the White King colony were purchased commercially. Each bird was exposed to 2,500 rads total-body roentgen irradiation with a cobalt-60 radiation source at the Oak Ridge Associated Universities Medical Center. Dose response curves were established previously (Shaw and Vermund, 1961) and showed that .
