Recovery Effect of Highly Polymerized Homologous Liver Deoxyribonucleic Acid injected into Lethally Irradiated Rats : Histological Examination of the Digestive Organs

IN our earlier reports it was pointed out that X-irradiated rats ( LD 100 ) treated with highly polymerized nucleic acids survive lethal doses of radiation. The data obtained showed that the treated animals survive the critical 30 days period, gain in body-weight and the contents of their splenic nucleic acids reached normal values within a short interval of time 1–3 . The adrenal glands also seemed to be less damaged than in the irradiated untreated animals 4 .
