Abstract
Summary
After 800 r of whole body irradiation to rats, a nucleoprotein-rich fraction of the intestine is diminished in amount and also in its content of total phosphorus, total nitrogen, dry weight, and ash. The greatest loss of phosphorus is derived from the nucleic acid fraction. In addition, the weight of the intestine, as well as the viscosity of its alkaline solutions, is significantly decreased after whole body irradiation. These data are interpreted as substantiation of the idea that one effect of whole body irradiation is the degradation of nucleic acid.
