The paste was made of calcium hydroxide and iodoform with the addition of silicone oil. Whole body, light, and electron microscopic autoradiographic surveys were used. Additionally, quantitative analysis using a liquid scintillation spectrometer was performed on the component dimethylpolysiloxiane. The calcium component moved to the bone tissue through the body fluid and blood, and some of it was excreted through the digestive tract. The calcium came partly from the calcium components of the paste in both types of heterotopic calcifications: dystrophic and matrix vesicle. Some of dimethylpolysiloxane component also passed into the digestive tract. Furthermore, the dimethylpolysiloxane played some part in the calcification caused by the embedded paste., Editor, Toshiyuki Kawakami, Language Editor, David M Carlson, viii, 232 p. ill.
