Crystalline phase of calcified lesions in heart and tongue of DBA/2NCrj mice was analyzed either chemically or using an X-ray diffractometer. The uncoated surfaces of the calcified lesions contained calcium and phosphorus together with very small amounts of other elements. The Ca/P weight ratios of the calcified deposits from heart before and after heat-treatment at 400℃ for 3 hr were 1.30 and 1.64, and those from tongue before and after heat-treatment were 1.46 and 1.81. Furthermore, while the X-ray diffraction patterns from heart and tongue deposits before heat-treatment did not show any diffraction maxima, the patterns after heat-treatment from both heart and tongue deposits were coincident with those exhibited from hydroxyapatite. From these results, it was suggested that the crystalline phase of calcified deposits in heart and tongue of DBA/2NCrj mice might be hydroxyapatite.
