Abstract
Radiation effects on permeability of liposomes with different lipid compositions and the content ratios were investigated using X-rays. Liposomes constituted from an unsaturated phosphatidylcholine (PC), a saturated PC, and cholesterol were selected. As a result, we found that a PC with bis-allylic hydrogen, particularly dilinoleoyl PC (DLOPC), is essential for the radiation sensitivity in permeability, and it can be controlled by changing DLOPC content and dose rate. These characteristics are contributive to a novel pharmaceutical and a new-conceptual radiation dosimeter.
